LT1 Twin Turbos?

Is there any kits? How much? Whats a good estimate to run a setup @ 500 hp as a daily driver and what kind of other mods to the car would be recommended? Please help.

Currently No. There is no tt kits available. One single but no twin.

What is needed to run 500 hp daily.

*aftermarket computer for starts. Can be done with a stock computer and tuning but to make the car work to its optimum might as well get a system that will compliment the car best.
*stronger bottom end, maybe just some forged pistons but a bit more freindly in case you detonate.
*Fuel system can be just a better fuel pump intank and one inline.

Around how much should I expect to spend on parts alone? And an approx. labor fee? any ideas?

Thanks

I know Gale Banks is working on a system to be completed by the end of the year!..You can contact them direct for more info as it has been discussed on this board before...good luck

brady_96z is building kits. I would talk to him about options. I'm not sure what the prices are, but there is no doubt his WORKS!! I've seen him run at the track. This past friday he won the Street Car Shootout at the Mobile Dragway in Irvington, Alabama .......That car is BAAAAAADDDD!!!!

Cant wait to see what Brady builds havent heard that he was building a system. The kit he has on his car was made by Burheader headers. I am sure he has seen alot of ways to improve on that kit though.
The gale banks system has been being built for a while and has not come through yet. From the prelim pics it should be interesting though.

meathead is just that: a meathead.

We're going to build something, but not anytime soon.

I'm going to work on a single turbo setup first, packaging twins requires alot of work. More work than most people are up for.

Don't get your hopes up, it's still a long time before we offer anything publicly.

sorry for the local loudmouth http://web.camaross.com/bb/wink.gif http://web.camaross.com/bb/biggrin.gif

I bought a "kit" from burhead headers, it didn't fit. Not even close. We spent about 3 months working out all the bugs, including re-working the headers to fit properly. I learned alot from the experience and decided that I (with help) can build a better "kit" than I bought.

I'm not competing for any business, I'm not trying to make a living, but I will build someone a nice turbo kit for their car http://web.camaross.com/bb/smile.gif I like working on cars, especially fabrication.

We just need a little time to get things in order, we'll let y'all know when we are ready for a customer.

...Brady http://web.camaross.com/bb/smile.gif

I want to be your first customer. I know that there are a lot of guys out there looking for a good twin turbo kit, and I am one of them. I would be willing to shell out the dough for that kind of power. I know that they won't be out for a while, but I will be waiting.

------------------
95 White t-top Z28 M6 Mods include: Hotcam, Macs w/ offroad pipe, flowmaster, airfoil, TB bypass, !EGR, !CAGS and a B&M ripper shifter. Many more to come. I will have some times after I break in my motor.

http://www.chargedair.com/

Good luck getting a kit from CAS...hehe Only 2 things out there right now is the Turbotech kit and the PTK kit. I would lean towards the PTK kit over the Turbotech one.

Jose

i saw you guys said there were one turbo kits...are these like one gigantic turbo or does it run off of only one side...and who makes these. there has gotta be alot of lag though, right?

Check out my signature for some picts of my twins:)
Everything is done I just have not uploaded picts to my site.

There is a Twin Kit coming out from www.Turbolocity.com I know its been awhile since they started this but my car is the prototype car for there kit and it will be coming home this weekend with the completed kit on it.
Contact Brad at the web site and talk to him about pricing and availability. The kit is top notch and should put out some good numbers when I get it on the dyno in the next few weeks...

Tom

we should have a tt kit available with in the next 3 months.

probably just like that Banks kit that was gonna be out 2 years ago.

our progress has been hindered by lack of capitol at the moment, hehe. we have given up on the twin kit for the time being, as we didn't see much purpose in it when our single kit is looking like it'll be good for about 500 rwhp on a stock engine. in any event i will post updates shortly on that particular kits progress and i'm terribly sorry for the delay. trust me it's killing me.

david

It would be a cool idea to snap some photos periodically and post on your website. Good luck!

Here is a twin kit advertised... don't know anything about it though.

http://www.nothingbutperformance.com/LT1turbokit.asp

I wish they would show some pics of the kit. I'd like to see the plug access as well as the overall fit. $7K is a steep price. I'm thinking of registering my car in Nevada because Cali won't permit any system without their kickback... I mean CARB approval label.

they had pics posted here , haven't checked in a while

How much are we talking for your turbo kits. I am assuming there would be no possible way your kit would be smog legal, or at least that is what I am assuming. How much power could you make with a 383. I am looking for a pretty moderate setup that when smashed to the floor board will spin the rollers and put on a little show. However I use the car for daily driving. Is the setup you are building strictly for racing. Would I be able to get away with a 91 octane gas in California. What parts are you including with the kits. I checked the site and did not really see much info on them. What are some of the differences between your kits and the competitors. Will your kits include items like fuel injectors or fuel systems, proper blow off valves, wastegates and upgradeable turbos and intercoolers. Also out of curiousity would the items be available separately from the total package you are putting together in case a client wanted to build the car in steps or little by little. THanks

I think they Improved the CARB approval process. STS will take 3-4 months to have their system approved... If all goes as planned.

Gale Banks has announced the release of their twin-turbo setups for Chevy 350 applications. They also have a complete crate program as well.

http://www.torqueandchrome.com/350twinturbo

You can PM me with any questions you may have. At this time, the valve covers are not available, but can get the manifolds by themselves if you would like. $900

A complete twin-turbo package is running $5995, so find your best offer, put it together in a weekend, and fly to work on Monday.

Cat-Backs as well..

torqueandchrome - it looks like a great package but I think we'd have to cut a hole in our hoods for the unit to sit on top of the intake manifold... or get a new hood. How high does the pressure chamber rise above the intake? It looks like it fits on a carburetor-type intake manifold with fuel injection... how will that work with the MAF?

Is it CARB approved?

The Exhaust will need to be fabricated after the turbine... right? Or does it bring the exhaust down to the y-pipe then out the stock exhaust?

Is there a smaller kit for 600 HP? I've only got a 10 bolt in the rear... 500 RWHP is enough for the street... for now ;)

Air filters? They don't come with the kit? How do they hook up to the LT1 or LS1 f-bod?

Sorry about the questions but to make it work, someone's going to have to open the door. :)

On to the turbo questions:

It is applicable for the TPI camaro/firebirds and has been designed to
accomodate those hood tolerances.The valve covers are something that is
included on the complete engine package,but not yet avail for sale
separately.I am working on that for my own car!!!

the system is designed as a injected setup.If a customer has a Carb,then let
me know and I will see if I can dig up a price on our old carb kit for
you.If a customer has a TPI setup then he/she could use it but they would
need larger intake runners/manifold and ported stock plenum as well as some
modification to the boost tube assembly.We recommend using our plenum and
getting an Accel DFI or holley commander engine management system which
includes the new throttle body,ECM and all the necessary programming to run
the engine seemlessly!

the kit on that page is a generic kit for 350 sbc's...........its NOT for the LT1 in any way and it wont come even close to fitting.

it would probably work for 3rd gens, but i dunno. for sure.

Brady, Blownengineering, etc. Put me on a list for info on a twin turbo kit when it's on the horizon. I should be done working on my boat early this year, so then it's back to the car.

For some odd reason, my website still gets an average of 600 user visits per day, even though I have not updated it in over 2 years. The next project (TT383) will be covered extensively.

The project goals are 900+rwhp...more than enough for the 200mph daily driver goal.

Here's the report from Gale Banks on the Twin Turbo manifolds for the 3rd Gen F-body

If you want the manifold kits I have them IN STOCK now ready for
shipment!...List price is $900 for standard port heads. We are also releasing a style of manifolds to work on the newer LS1 Fbodys and Corvettes soon as well,but I do not have a part # or price on that as of yet. Other components such as the wastegates,turbos etc will be avail as part #'s separately with pricing but as of now I have not been given that information as of yet.

The kit will fit in an 3rd gen Fbody as its original design that we made back in the 80's was based off of those cars.This new kit with the additional of its fuel injection capabilities will allow the kit to be adapted in a much broader application range,such as trucks, Corvettes, hotrods, etc.etc.

if you have any further questions let me know,but i can ship manifold kits now!

I leave you with information. You can contact me for more info..

Damian Walsh

Just wanted to let you guys know that there are twin turbo manifold set which are available to ship. The below text is from an email that I have been using to respond to many questions about the 350 SBC twin turbo packages from Gale Banks Engineering.

The question that I have had answered relates to the availability of just the manifolds.

Here's a reply from Banks' I got this morning..Plus the other email with more FAQ.

Hi,

It's Damian from Torque and Chrome. I wanted to let you know
what I was doing with the twin turbo setups from Gale Banks,
and how I will be getting as much information from Banks as I can regarding the parts.

3 top FAQ that I am trying to get answered:

"What other modifications do I need to do to my TPI Stock engine"

Banks includes in the information on there systems, that to operate
"seemlessly" is the addition of this multiport system.

HOLLEY COMMANDER 950 MULTI-POINT FUEL INJECTION SYSTEM

These are complete systems engineered to provide all components and hardware
needed for your custom installation. The intake manifold, billet throttle body,
billet fuel rails, injectors and related miscellaneous parts are
factory-assembled and tested prior to packaging. Holley takes this extra step
in quality assurance to verify the performance, quality and integrity of the
system.

Holley Commander 950 System Benefits: - Vastly improved fuel distribution and
cylinder filling; - Excellent throttle response, drivability and fuel economy;
- Impressive torque and horsepower gains over standard carbueration; - Superior
idle, warm up and part-throttle driving characteristics.

Commander 950 Software: The Holley software included with the Commander 950 is
Windows-based (3.1, ‘95 or ‘98) and is much easier to use than software that is
DOS based. This software enables the user to program system parameters in real
time. Changes are instantly sent to the 950 Commander ECU or “on the fly” for
immediate evaluation. All sensor data is viewable from the fuel map screen. The
spark and fuel maps can also be viewed in a graphical form, which helps to
better visualize the data. Sample fuel maps are included to help you get
started. Fine-tuning, however, is required in all installations for best
operation. A data acquisition feature is included for evaluating on-track
performance.


Commander 950 System Features: These stand-alone systems are pre-assembled at
the factory and contain all components necessary for installation, including a
detailed installation guide:
Commander 950 ECU - control functions are accessible with supplied Holley
software and fully programmable with a personal laptop computer with WIN 3.1,
’95, ’98, NT.

Throttle bodies available in the following styles:
1000 CFM billet w/4-bbl square bore and 5” air horn;
2000 CFM billet w/Dominator flange.

Fits the following Chevrolet engines:
Small block w/23-degree standard port heads (early & late);
Small block w/Vortec cylinder heads;
Big block oval port heads;
Big block rectangular port heads – including tall decks.

Sensors - include throttle position, MAP, engine and air temperature, exhaust
oxygen and idle air control motor.

Wiring harness - designed for “plug-in” installation; temperature-insulated and
weather-sealed.
Separate systems available for naturally aspirated, forced induction (up
to 14.7 psi) and forced induction (14.7-29.4 psi).

Adjustable timing - is available with any of the following distributors:
Any distributor that has a “locked” mechanical advance and a magnetic pick up;
Any distributor that is set up to work with a crank trigger (either magnetic or
Hall Effect)
The Commander 950 ECU’s adjustable timing feature will also work with any CD
ignition that does not have timing control (such as HP Annihilator, P/N
800-100) if used with one of the above-listed distributors.
Base fuel maps available at the Holley Web site. http://www.holley.com/HiOctn/TechSe...fo/950MAPs.html

Commander 950 Engine/Hardware Compatibility: 4-, 6-, and 8-cylinder engines;
Can operate as a “speed density” system; uses engine vacuum to sense engine
load;
Can operate in Alpha-N mode; uses throttle position as indication of engine
load;
Engines with wide fluctuations of manifold vacuum at idle due to radical cams.
1-, 2-, or 3-bar MAP sensors; naturally aspirated engines; forced induction
engines.
GM/Chrysler-style IAC motor - idle stabilization and control;
Knock sensor; - Will operate in either open or closed loop;
A closed loop system uses an oxygen sensor to monitor and adjust the
fuel/air ratio for optimum performance.
Port fuel injectors; - Controls up to 8 high impedance injectors / up to 4 low
impedance injectors;
Throttle body fuel injection systems;
Throttle body with progressive linkage; Throttle body with 1:1 linkage.
Fuel control for: - Initial cold start and warm-up; - Acceleration enrichment;
Start-up enrichment; - 16 x 16 fuel map.
Controls CD ignition timing; - Holley Annihilator ignition;
Programmable RPM scale.
Programmable fuel pump control.
ECU size is 5.5” x 4.75” x 2.0”.

"Can I purchase just the manifolds?"

Torque and Chrome is currently finding out how hard it is going to be to get
just the manifolds. If I am able to secure that they will ship quickly enough
(21 days) then I will do that as well. Please note that if the manifolds go by
themselves, the list is going to get bis as to who's getting them first. I
believe that there were issues the last time Banks' offered this setup, so
we'll all be finding out together.

"What about downpipes, and connecting the system to an exhaust?"

I am going to have to find that answer out as well. At least I will get a good
idea on how to do it better than others. I will let you know what I find
out...

Allright!

I hope this will at least let you know that we are working on the answers. The
systems are being advertised, we will wait to see what shakes out.

I will more than likely post what happens with this offer on a page you can
reach from our Gale Banks web page. That should happen over the weekend.

Thanks again for asking,

HOLLEY COMMANDER 950 MULTI-POINT FUEL INJECTION SYSTEM



wait...are you saying after you buy the turbo kit, you also have to buy the holley commander system?

thats like another $1k (accoprding to summit), on top of the $6k for the kit?....hmm.

What would make the task of tuning and operating your twin turbo package easier, would be the Commander 950 system.

You do not "Have to".....but, it would probably make the job of tuning the system much, much, easier. They have included this information so that if you have the budget, you can get this system in addition, and have an easier time of insuring your package runs great from the get go.

There are many additions you can add, and many items you can probably take away from the package, but at what cost to the performance of your $5k investment.

I think it's a good thing that they have supplied us with the information to make our lives easier if we choose. That, I think is the reasoning.

Folks have been putting together turbo packages from scraps. AND, performance has probably suffered due to many setups not being able to get properly tuned. this additional engine management system probably is a system that would help even the project turbo packages operate on a higher level of performance than just test and tune setups.

ahh......ok, thats all i was asking.

Well, I checked, and here's the low-down on that one:

THE KIT CAN BE ADAPTED TO AN lt1 APPLICATION...the
manifolds,wastegates,turbos etc all ca be used.On that type of an
application the customer would want to use his stock plenum and have is
ported.Our plenum would not be applicable for that type of a setup
generally.We would deduct the plenum out of the price of the kit.Programming
would be done via the F.A.S.T system or other system like DFI or Commander
950.Items such as the Alternator,A/c etc need to be relocated for the system
to work or a customer could purchase our Front drive system with all the
accessories included to work on that application.

have they tried fitting those turbos into a 4th gen engine bay with that setup...........maybe it just looks decieving, but i dont think the hood would close

There's a question that many folks have asked, and I can't say for sure at the moment one way or the other. What I have gotten out of them is that the fit will be very tight, and some applications would have to mod the hood for fitment of the system.

BUT, I'm not going to say that's the final word. I will find out from Banks or from other folks who have the system installed what they have had to do to get it to fit in height.

Anyone out there have an answer that would help us???

Sorry to have to butt into this thread for this, but we gotta be fair to all.

torqueandchrome:

Not meaning to be rude, but do you relaize this site is supported by vendors who pay for their advertisements and the right to promote product here?

It would be unfair to not ask you of the same.

Before continuing, please have a look at our advertising information here:
http://www.camaroz28.com/advertise/
And contact us to hopefully get something up.

We'd appreciate it! Thanks!

i havnt heard of any one using them yet but charged air systems offers a tt kit for the lt1 camaro. its a little less than $7000 but it seems to come with every thing you need including injectors and programing. if any one else has heard good or bad things about this please post.

austin

theres one guy on ls1.com with the CAS twin kit on his ls1 with pretty good numbers...........havent heard of anyone using it on an lt1 yet even though its been out awhile......i think its just way overpriced......most of the guys who are serious about twins just custom build the kit for much less.


as for buying from CAS, i would only do that if i was picking up the parts in person........many threads on other boards have been dedicated to CAS being late on sending parts after payment.

That's good news. I wonder how much it costs for the "complete" kit to bolt and go (Intake manifold, waste gate, boost controller, etc).

Just my opinion...if I'm going to spend that kind of money (and I am at some point) on a kit, I would want it built for my car from the ground up, to ensure as much as possible that I will not run into problems. I woudn't want something that "can be adapted" to my application...sounds half-assed.

well the kit isnt half-assed, it just isnt meant for the lt1 or 4th gen engine bay.

id just be pissed if i paid that kinda money and didnt get an intercooler, wth?

Still means I'd have to do things to make it fit in the car. A specific kit should be basically bolt-in.

thats my point.......its NOT a specific kit for us.

On the previous post it was stated that if you buy the system with the accessories, for a front drive package. then it will hook up directly. Only problem is, that the system as you see it, and with your stock accessories and brackets, is not prepared for this package "as-is". I really don't think that when you look at any of these twin turbo installations will you find someone saying "oh, it's like the car was made for this system" , or vice versa. The manufacturers did not plan on Banks introducing these kits, and they did not make their engines like they were going to market a twin turbo themselves.

It's you and me who do the work to get our vehicles powered-up, we need to find good quality equipment, then find the best setup to work within our engine compartments, and budgets. If one is out of whack, then the other one usually does not follow behind.

The system IS a "generic" setup that has to be perfected for use by each person who purchases the equipment. Banks has been giving us the information to cover all the bases, now all that has to be done, is to hit the homerun.

If you decide to install one of these on an LT1, then be prepared to spend a little more (time and money), it was made with the another vehicle in mind, but as they grow the line, you will see that there are OPTIONS that allow you to get the best results out of the system with whatever your SBC application is.
