Is a YS-trim streetable?

I was just wondering if it's possible to underdrive the YS to around 12-15 pounds of boost on a 355? Will it still be streetable?
Would it be possible to use a serpentine belt (maybe a 12-rib) to drive this thing. I used a 12-rib belt on the ati pretty successfully, with the exception of the tensioner.
And my final question is regarding the Vortech aftercooler. Why can't you use a big blower like the YS on this, where is the restriction? Is the piping too small or are the heat exchangers too small. You would think if they designed a system for high performance, it would accept a race blower, right? I e-mailed Vortech with the same questions and got no reply.
It seems to me they should make a race kit for the Z28. Look at all the stuff for the 5.0. No money in it I guess.

Thanks,
Ed

You can pulley it to run the boost that you are looking for and be totally streetable .The Vortech Aftercooler will be sufficent on a YS at these levels. I build custom brackets for a YS on an lt1 with a very trick tensioner setup. This is the same setup I run on my car with 24lbs of boost and a large FMIC.No belt problems last 25 passes!all at 9.1 or quicker

Gee, thanks for that info. I'm not looking for that much boost, just around 12-15 pounds max, but possibly more potential in the future. I have the aftercooler with V2 right now, brand new. I've also got the ati twin intercoolers, if your familiar with those.

I'll see if Vortech wants to exchange their V2 for a YS, plus all the other stuff I didn't use in the kit. I was kinda concerned because the V2 looked a lot smaller than the ati P600B!. Please e-mail me with any more details about the custom brackets-pulleys you can make. :D Sounds good.

I have a set of Z'8s custom brackets for a YSI on my new set-up. They are beautiful pieces. Thanks again Chris :D

I am pretty sure Vortech with do an exchange for an upgrade but don't quote me on it you'll have to contact them to be sure.

Your question regarding the streetability of a YS, well I plan on running my YSI on the street more then the strip so I would have to say yes to it being steetable. How streetable is the question that both you and I have at the moment. I am sure I will be going through alot of tires this summer. ;)

We'll ya, I figured that.

Tom,
What pullies are you using? Is is serpentine or cogged?

How loud is the YS trim btw? Similar to an S trim?
Thanks for the replies guys.
Ed :cool:

>are saying thats acceptable ? :confused:
I would sell it on ebay to get your money back for the head unit that you don't want .

Bowtie, after reading up on the exchange program, I see what you're saying now. I thought you meant if you exchanged the t-trim and gave Vortech the $750, you would get a YS in exchange. To get a $750 credit for a brand new blower is ludicrous IMO. Looks like selling it on e-bay may be the best option.
Thanks for the heads up!

>I think it really dumb that they won't exchange a brand new in box head unit and some cash for an upgraded head unit .
I too will upgrade to a YSi -trim after I get some use out of this T -trim first .

My buddy bought a YS-trim and was hoping to use the ATI twin high flows. Using the stock Vortech bracket there was no way to rotate the blower and have the outlet point straight down. Your best bet would be to stick with the aftercooler. :)

I'm not familiar with the ATI setup, but why couldn't you make the blower exit parallel with the ground towards the driver's side, then to the intercoolers? This is how I'll do my t-trim with an intercooler, unless the YS trims are just that gargantuan that they can't point to the side either...

No need to have the YS point down. I have my YSI pointing torwards the drivers side wheel where the piping comes from the intercooler. Fits perfectly fine.

That's exactly what I figured out too by looking at the V2 bolted on the bracketry. The problem is the bracket design, specifically the lower bracket. It will be in the way if you try and rotate the volute so the outlet is facing down. Like Tom said though, it is possible to point the blower outlet towards the driver side wheel.
If this is true, it shouldn't be too hard to use the twins, it would probably be necessary to custom pipe the outlet to the intercoolers though.

I own the YSI on an LS1 and it makes a very undesireable street car.

I dont see how a blower would really effect streetablity. Will it make boost down low? no. is it a good choice for a street car?not really.. BUT, when you are just driving around.. you shouldnt even notice the blower.(aside from the whine)

It's obvious that you don't own an YSI.

So are you going to tell us why it doesnt make for a good street blower?.

If your only gonna run 12-15 psi, why bother going YS. Vortech makes a complete kit that uses a T-trim. That would good enough for 800-900 hp.

I have a 3.12 Vortech pulley for sale, that might keep the boost down.

I would sell my YS Trim at a loss to get a YSi, email me at prostockjohn@hotmail.com it has a grand total of 15 dyno pulls on it.

A blower is just a blower. Won't affect streetability at the 1200-1600 cfm level.

A T-trim will not make 800-900 hp on an LS1, unless you add NOS.

Stealth, any particular reason you think that Vortech went through the time and trouble to get the YS series smog certiified?

I made 746rwhp, unlocked T400, with a YS trim (1500 cfm), Griffin FMIC, FAST system, VP C12 (108 motor octane; leaded), and 17 lbs of boost at 6800 rpms. That was with the 8.0 crank and 2.85 blower pulley setup. 8 rib stuff.

So in my mind I would be looking at blower pulleys in the 3.12 up to 3.3 range.

Why not.. it has made over 900 on a 414CID LT1 why not an LS1?

Thanks for all the replies guys.

I've finally decided to give the V2 SQ trim a try first and see what it does, as I might be happy with it after all. I am going to have to relocate part of my fuel system to install the aftercooler too, and possibly relocate the battery and install a bigger reservoir tank. At least the gear whine will be gone, the car sounds better without it IMO.

If this don't work, there is always the YS trim waiting in the wings :p
Maybe by then Vortech will wake up and build a kit for the LT1.

Id say go for the T-trim the first time ;)

I thought the Ls1 blowers were reverse rotation. How exactly would this work on an LT1?

Sounds like an internet rumor to me. The T-trim makes 1200 cfm, which cannot be converted into 900 rwhp on a 414 CI motor. We could ask Vortech, but I have not even heard of a 1600 cfm YSI-trim making 900 rwhp on an LT1 or LS1.

FLYWHEEL HP! Not rwhp.. rwhp its out of its range...

Vortech said that S-trims where rated to 680 flywheel HP... and there where cars making 630rwhp!!!

As for the T-trim...
If its a rumor i dont know...

http://96silverz.cz28.com/

Check that one out.. he did 825 on pump gas and 925 with a 402CID, sorry not a 414 I was mistaken.

Well, my first question is, how did he measure flywheel hp, was it on an engine dyno? I doubt it.

Second, I raced an S-trim for 2 years on a 346 LS1. It will make around 8 lbs of boost and maybe 490 rwhp with a 4L60E, heads, cam, headers, aftercooler, etc. I'm skeptical about these Vortech numbers.

We need to be clear here. If I could figure a way to bolt an S-trim to my 622 BBC, it might make 1000 hp, but that would not be relevant to LT1 and LS1s or "blower" performance.

I've made ~775 rwhp with a YS and I will dyno my new YSI setup in a week or two, but I doubt that a 400 ci LT1 or LS1 will make 850 rwhp with a 1600 cfm YSI blower.

I could probably make about 800rwhp with my 348ci, a YSi, and C16. Might be able to squeeze 825rwhp out of it depending on how well the fuel upgrade worked.

An s-trim is capable of the same thing more or less depending on efficiency of the engine, but it has a range... An engine regardless of its size or configuration can make the HP given by how much air it ingests vs how much air it expells... If the engine can ingest (bbc) more than the supercharger can send there will be 0 boost... No matter in what engine the Supercharger or turbo has the same range potential.. In that case it will NEVER make 1000rwhp on a bbc.

That dyno WAS on an engine dyno....

George baxter and znines did a bit more HP than 800rwhp with a YS-trim... I would love to know why you say this is impossible?

Regarding streetable.. I think we are way beyond the limits of streetable when we start talking about 700rwhp+ why? because pump gas will not support it, and I dont think that crusing around town with a car that sucks 13mpg on $8.5-$9 a gallon is something that is streetable. If you lower boost to run pump gas then its another "setup" and it doesn't count as street performance.

Z8's (chris) car makes over 900rwhp..... this in unlocked t400, small a/w, hydraulic roller cam, and stock lt4 heads/intake... this is also proven by the 159.64mph trap speeds accomplished at 3450 race weight...

I have made well over 800rwhp with 306, hydraulic roller, NON intercooled, serpentine belt driven, unlocked auto with 6200 stall converter, YSi combo... it is common day in the renegade world of mustangs..

My street car, with 93octane, run a YSi making 11lbs of boost (3.33 pulley upper and 8 inch lower)... i spin the car to 6200rpm and it will run bottom 10s all day long on pump gas...

The YSi is a very versatile blower... it is the head unit included in MANY street kits ranging from BBC carb kits to 5.0 mustang tuner kits... Vortech has spent a ton of money to have the YSi Smog certified.. It was DESIGNED for the street...

The YSi is the blower to purchase... you can grow into the capabilities and not have to spend another dime..

my car can be located on the vortechsuperchargers.com webite frontpage..

thanks

This is your first post.. congratulations and welcome to the forum..

What about running in the range of 700-720rwhp@12-13psi boost.. how does it handle boost down low? does it create enough boost down low?

THanks

THat was also one of my major concerns and why I chose the T-trim. Although I feel that at the same Peak HP (700s)level the YS should be more efficient than teh T and that should be a lot more power from the YS, but really unsure as I have not tested it yet.

i believe 700rwhp on pump gas with no cooler etc is a little out of range... the YSi's impeller was created for low rpm boost.. like i said, it is the best of all worlds.. Good low end, great mid end, and even better top end..

FYI, i tune and drive Z8's LT1 camaro and I have been involved with forced induction for over 10 yrs..

thanks

Looks like we've confirmed that everyone has a different view of the topic. Not surprising.

Good to know... 700rwhp with vortechs aftercooler... I will use a tank located in the trunk.

Now im interested in a YS-trim... I always thought that the YS trim was a little lazy from what mustang guys tell... and that the Novi 2000 was better in that dept

actually, it is completely the opposite... I ran a novi 2000 for 3 yrs while being sponsored by Paxton... I am very familiar with the Novi and the datalogger showed that the Novi had about a 3lbs drop off on the gear shift compared to the YS or YSi...

You may be confusing your info with a "Y" trim from back in the day..

YSi just came out in the late fall of last year so the YS has been going high 8's and low 9's in Renegade for over two years.

No, not confusing, just retelling what I read on the mustangs forum... But, since now there are more people running them I guess it wouldn't be such a problem..

I wonder how the YS-trim will perform with vortechs aftercooler, since its 3" only. There is a guy here that did 752rwhp with the vortech aftercooler and a ys-trim.. his car was white.. I cant remember his name.

I was thinking about the Novi 2000 also, since it has helical cut gears like the V2. Maybe that is the reason for the boost drop off during shifts.
Anyway, same story. Paxton don't make a bracket for the LT1. Neither does Vortech for the YS or YSi. Go figure. It couldn't be that hard, could it?

Well if you "modify" the vortech one you could convert it into a Novi bracket.. how hard can it be? i mean... If bob bishop makes brackets for c5 brakes, why cant a single or dual plate bracket be made similar to the S/T trim to support a novi?

Anyways the S/T-trim bracket can be modified to accept a YS-trim which is what people have been doing.

Z8's ran modified S trim brackets for a long time before coming out with his custom brackets.

The Highlander-
whats cool about FI, is you dont have to build a setup that only gets 13mpg to make 800+rwhp! my turbo 383 got over 20mpg on the highway, and 16 or so in the city depending how I drove it.

Also, with ablower you can easily just not shift as high and/or pull timing to run the car on the street. With my turbo it was even easier, only run 12psi (660rwhp) on pump fuel, and then turn it up if I wanted to faster. I am pretty sure I coulda made 700rwhp on pump gas, but never had the chance to try.

Actually my goal is to do 690-705 on pump gas... @ 12psi or so on boost...
And then im done :rolleyes:

But... I will hope and see if that mark is possible on pump gas and 8.8:1 CR.
