Guys, I'm in the market now to go with a Supercharger and N2O combination and I'm wondering what the largest Supercharger is that you've installed on an LT1/LT4 and what was the engine build and hp that you produced.

I'm looking at building a Callies forged bottom end 383 4-bolt mains engine with a 50-100 shot of N20 to run on top of the Supercharger.

On the ATI side of the house....

I'm currently looking at the ATI ProCharger D-1SC and the F-1. I've heard that the F-1 won't just drop in place as you'll need to do some modifications to the block (grinding), but it will fit the D-1SC bracket. I'd actually love to go up to an F-2.

Here is the ProCharger Model Specifications Matrix

On the Vortech side of the house....

I've not yet explored what I could go with on this side of the house, but I'd like to hear what you guys have done.

Here is the Vortech Supercharger Specifications Matrix

Thank you all for taking the time out to read this and assist where you can.

 

How much power are you looking at making? What kind of budget are you on?

As far as ATI blowers I would recommend going with an F1 if you want to keep the install somewhat simple. The only thing you will have to do is grind away a little of your block (not a big deal at all). If you want to go anything bigger than that you will need to hack up your car up. Plus you will need a custom bracket.


If you want to go with a Vortech then I would recommend going with either a YS-trim or a YS-I trim. I have heard that you have to modify your existing bracket to get the YS to fit. There is a guy on here by the name of Chris Sikora that does custom brackets for Vortechs.

 

Thank you for the response....and I'm sorry I went too quickly on my keyboard without inputting more in detail.

The engine has not been built yet, but I am pushing for 450-500 flywheel hp prior to the power-adders.

As for the budget....I don't want to exceed $12k on the build and power-adders. I'm partially sponsored by NX as well as ATI, so it definitely helps the pocket book on the power-adders side of the house.

I just want to ensure that I make some sound decisions here and this is why I'm hitting up the audience here to see what others have found worked for them or others.

The goal is to get my slug into the 9s, whether it's high or mids and still keep it a weekend cruiser a couple days out of the month.

 

If you are wanting to get into the 9s, a D1SC on a built motor will get you there...as for the $12k budget, well, that is another issue all together.

 

I think the F1 will fit, but the F-1R will require some cutting by the freeze plug and maybe some notchin' on the frame.

I thought George Baxter was running a bigger blower than a YS(X-trim maybe??). I know there's a couple YS-powered LT1s around and there was just a YS-trim kit for sale about a month ago for an awesome price.

 

IDOXLR8, I attempted to PM you with this, but your inbox is full and I didn't find an email address for you.

Sounds like you got yourself a very nice set up....and I also want to thank you for your response as well on the site.

Do you mind showing me some pics of your set up as well as any pointers. It's looking like I may just go the F1 route on the ProCharger.

I'd like to see how you have your fuel system, etc.

Thank you very much for your help once again.

 

i agree you might be able to do it on a d1sc with your mentioned bottom end as far as $12,000 dont know if that will be posible unless you want to up the n2o i had similar set 383 with d1sc and put approx 600-640 and i had aproxx $20,000 into it

 

If you are going for nines, I'd go straight to the F1sc. It will at least leave you some growing room rather than maxing out a D1sc off the bat. I would also do a custom front mount intercooler as opposed to something like ATI twin intercooler kit.

 

You don't want to use a blower any larger than you need. However, you don't specify if this car will maintain street accessories or not. That makes a huge difference in mounting a blower. As has been stated, the Procharger F1 or Vortech YS are as large as you can fit in the "standard" location (lower front drivers side) without major work. In addition, This combo can generate large amount of hp. I have an LT1 F1+N2O combo and without getting all the bugs worked out last year it drove my 3,850lb car plus 250lb me (4,100lbs) to 10.2 @ 140.4 with more left in it.

So, how fast do you want to go and how much do you want to spend? Does your $12K budget include the fuel system? Drivetrain upgrades? A shortblock is going to be $4-6,000 and then you will need a valvetrain, heads, fuel system, etc. Not to mention the blower. Specific parts depend on the budget. I have good luck a Callies crank, Lunati Pro-Mod rods, and JE "blower" pistons. This year, I am cranking it up and using a Callies crank with JE pistons again but stepped up Oliver billet rods.

Did I mention you are going to need one hell of a fuel system?

Thank you all for the replies, and whether you realize it or not...you are definitely all helping me look at different angles on this and that is just what I was hoping for.

The Z is located at: www.projectspeedy.com

It's a 1997 Z drop top and I've been working on the weight issues. As for what I've already completed in preparation for the engine, which I'll just list the major components....

Drivetrain - Moser 9" (spooled), Spohn Extreme Duty Driveshaft

Transmission - TH-400 with Manual Valve Body

Suspension - PA Racing Chromoly K-Member/Upper and Lower A-Arms, HAL 12-Way Adj Shocks, HAL Front Drag Springs, Spohn Adj Torque Arm

As for fuel system...I don't have anything in place as of right now and this is why I've also been in search for custom setups to gather ideas.

Tuning, I'm looking at the DFI system.

I had mentioned previously that I would like to bring this slug into the mid to upper 9s, and on a YS or F1 and a 50-100hp of 'squeeze' I'm sure I can get there.

As I've now been putting more thought into the dollar amount that's totalling up.....it's looking like yes....we will definitely be above my beginning mark of $12k as I don't have the fuel system done and some of the miscellaneous areas that will need to be taken care of which I'm willing to work with.

Rich, what have you gone with as for a fuel system? I'm still in search of people's setups as I'd like to look over pictures and see what everyone has already found what works....and what doesn't work. Why recreate the wheel....

Again, thank you all for the great comments and I surely welcome more of your thoughts to this ongoing build as I'll be checking in frequently on this thread.

Sorry, I currently do not have any pics of my car. I am in the process of putting my car back together. I am converting over to a front mount intercooler. I was way out of the efficiency zone of the twin high flows. If you do decide to get an F1 then I would recommend just getting the blower. The stock tensioner is garbage. I would highly recommend contacting Scott at SD Concepts. He make an awesome spring loaded tensioner. Also you may want to look at having a hard inlet pipe made. If you have any more questions please feel free to email me at phatct@aol.com..

 

As far as fuel systems there are two ways to look at it. Do you want to run a big external pump? If so I would highly recommend going with a Weldon pump, voltage regulator and AFPR. In order to get the most out of the setup you will have to sump your tank and have your fuel rail modified.

Another way to look at it is to run a twin intank setup. I am making over 700 rwhp without a problem.

 

I've got a twin external setup. The second pump is activated only under boost. No pics, sorry. I can describe it in detail if you wish though. Twin intanks may be a better way to go. The system I have (including pumps, filters, hose, relays, modififed rails, regulator, tank work, etc.) cost ~$2,000 However, it's intended to support up to 1,200hp which is probably overkill.

My previous system was much simpler and cheaper and supported 733rwhp. Single Bosch 255lph intank, stock lines, rails, and regulator, and a Kenne Bell "Boost-a-Pump".

I think if you do a lot of research into head units, it will lead to pick only one company...

Vortech.

ATI does not furnish compressor maps, and there has only been one 9 second F1 LT1 car in the last ten years, the Green Z formerly owned by Madman's buddy.

There have been a number of YS LT1 cars that have run in the 9's and even the first one to run 8's (Chris Sikora's car) has a YSi.

I also looked into running an F1R but I could not run the rpms to make the power with that head unit.

I'm an LS1, but I have a 348ci 9:1 motor and thru an unlocked T400 the car has pulled 720-746rwhp on several dyno pulls. By the end of March I anticipate it doing 775-800rwhp if the crank holds up. The only F1 LS1 like mine is at 598rwhp, but hopefully once Scott does a better intercooler we can see how close he can get.

 

Funny because the F1 has not been out for the last 10 years. Also you are going based on what you hear on the internet. There are plenty of people out there that have fast cars that do not post on the web.
