Supercharged LT5

[Eagle_4]

I looked on the forum in the search engine for a supercharged LT5 and couldn't find one. Anybody know about this or anybody that has done it? What times did they run? Any information would be helpful. Thanks!

Hello and welcome to the forum,

I have searched hi and low for the exact same thing, all i get is hearsay and stories! Someone even told me he HAS one on LS1tech.com but he wont tell me who makes it,.... hmmmm sounds fishy to me. My mechanic who works almost entirely on ZR1s and ZO6s says he has never heard of one. Good luck and God speed on such a worth quest! Maybe someone will mercifully shed some light on this for us, good topic!

While we are on the subject of stuffing air, check this out... coming soon, this maybe even better than that elusive supercharger.

(Look at the bottom of the page,... yeah thats right they are making a twin turbo kit that is supposed to be relatively inexpensive for the ZR1 coming out this month, hell even if its unvieling postponed it is something to definetly look forward to.



(thats 2 for me Zfactor! ;) )

[Eagle_4]

Wow, I'm liking this already. If I could do the 550 hp option I saw from a company in Georgia and then put the twin turbo on I'd be set and one happy white boy. Maybe it'll be out before too long and relatively in expensive as well. Thanks for the site!

Welcome to the forum Landon.

I've heard that there are a few blown Z's, but never have seen any proof of them existing. The TT's however do exist, so that will probably be your best bet.

Welcome to the forum Landon.

LPE did 4 TT zr1s, callaway, gieger, mallet, and now SGC is building one.

the TTS folks are planning one too.

while a supercharged zr1 is probably doable, I've never seen one.

I HAVE seen John L (rest his soul) make some 9.4x passes in Norm K.s TT LPE ZR1 @ 140+ at BG which isn't the fastest track in the world.

car launched pretty soft and struggled for traction.

this is a fully streetable car on slicks with skinny fronts and not at all a "drag car"

the SGC stage I car is targeting 55x rwhp and is going to be designed for low boost on a stock lt5. a stage II to follow with a build 368 and another 200 or so HP on top of that. these will be very streetable and reliable combinations and a nice alternative to the radical 415 builds making similar power.

I have an LPE 390 that makes 505 rwhp, but I can tell you it will be TAME in comparison to even the stage I TT ZR1. the torq curve of the turbos is just amazing.

I have been running around in a Turbo Buick since 1987 I can tell you first hand that the big boost turbo power is for real.

just look at the dyno numbers the supras put down. like the vettes, they struggle to hook it all up but trust me, they are fast!!!

I spoke to aaron last week, and the project is going ahead with the goal of having a car done by BG. lets hope so. it will be amazing.

Any idea of the cost for either stage I or II at this point?

Also, I know what you mean about boosted rides as I use to have a Turbo bike with vitually no lag, and it flew.:cool:

[rkreigh]

SGC hasn't finished the prototype or established pricing. but the target is somewhere around the mid 20s, not cheap but competative.

it will all depend on how much time and effort it takes.

the results are likely to be spectacular.

SGC does awesome work and Aaron is great to work with.

Final tuning complete and the verdict is in.
550hp@wheels
520ft-lbs@wheels
Hats off to Jim Smith for his relentless effort in tuning this thing. Thanks for not giving up.
Special thanks for Graham Behan of LPE for his continual technical support throughout this build. Graham was also supportive in helping us tune this motor and work through some of the problems we were having. :cheers:
Can't forget to give KUDOS to Aaron Scott and SGC for bringing me onboard to work on this project. Aaron has a nice shop and I would recommend him to anyone who wants some good honest work.
Finally, I would like to thank myself for doing a damn good job on this PIA project!:crazy:
I had the pleasure of driving the car today and it indeed feels strong. First and second gear are worthless at full throttle and third gear fights to stay hooked up. Car pulls strong to 7K and doesn't seem to give up any power. Real power comes on ~3.5K rpm when peak torque begins to hit. Look forward to seeing some track results with this thing, but I expect to see well over 130mph.

:thumbsup: =D>

Congrats to everyone involved :handshak:

Now that you have the experience the question is, are you going to be building any more in the near future?

:cheers:

[240Z TwinTurbo]

I believe SGC has plans to copy the kit and make it available through an install at his shop. It is too much work to sell as a kit and have someone install themselves.
BTW, new numbers on the car today.
565hp/532ft-lbs@wheels with 7.5psi of boost.

Any clue as to a price range yet?

[240Z TwinTurbo]

Please contact SGC for pricing.

I'll check with Aaron, but it will be more out of curiosity than any realistic chance I would buy the set up. Other than a few reversible mods, I'm going to keep my 1990 stock.

Thanks for all the info on the project. You and everyone involved deserve a hand. =D>

[supercowboy]

Is this done with the stock compression? Was The head gasket replaced with a thicker one?

[tomtom72]

After reading this all I can say is holy cow!! That is almost doubling the out put of a LT5!!! :cheers: to all the guru's of HP! Amazing results.

It makes me wonder what our motors would have been like in the newer chassis. That would be a sweet ZR-1 with all the advances in technology the C5's & C6's have. Tom

I don't know the answer to your question, but wanted to welcome you to the forum. :handshak:

Hopefully 240ZTT will be back to let you know.

Well I would not want the giant rear end or Barbie looks of a C-5, and I'm still undecided about the C-6's integrated headlights. However, I see you point.

:cheers:

[tomtom72]

Hi Z Factor, I agree with you! I wasn't thinking of the body stlye although I should have said that. I actually had a picture in my mind of my 90 Z body sitting on a C5 or C6 chassis' technicial achievments. Sorry, my apologies to the stylists at corvette. I mean no disrespect to 5's & 6's, but I like my Z's boby style just fine.

Although those cars have the only fat a$#'s I've seen that I could like!

May I say this? Oh heck I'll say it..."Hail the King! Long live the King!"
I'm sorry my Z is new to me! :cheers: Tom

[Is this done with the stock compression? Was The head gasket replaced with a thicker one?]

Supercowboy, The Stage I turbo was done with stock comp. (11.0:1) and hg's just like yours and mine. I believe the only mods to the car prior to the turbos was p&p intake, headers & B&B exhaust. Then they finished the test by adding an Xpipe. Stage II will involve lowering the compression. I will be seeing Aaron next week and verify this info.

I believe they would remove the headers for some type of manifolds is my guess there.
Here are a couple of questions that I have;
Did they use bigger injectors?, What system are they useing to tune it with?, Are they using an fmu or not?, How many pounds of boost was this with? What kind of turbos are they useing?

Cowboy, To answer a couple of your questions, here is some information I got from reading some other posts. 7.5psi with two Garrett GT30R turbochargers. 565rwh/532rwt- before the Xpipe.

I just realized that after my post. Thanks for pointing that out. I feel like a blonde :-D

[rkreigh]

the stage I is now going back to be converted to a stage II with lower compression and high boost. same basic setup for the manifolds, turbos, plumbing, and intercooler.

the stage II is the one to really watch. with high compression, only low boost is really possible, but it allowed to sort out the configuration and get an idea of how well things will work. the stage II will really run some big numbers but obviously will cost more since you need to do the 368 conversion too.

only way to fly IMHO. turbos and high compression only work really well with race gas or alchy if you are running enough boost to make it worthwhile.

SGC definitely got some impressive numbers out of the stage I, but the stage II will be the monster.

stage I is a great alternative to a full boogie 415 as it produces very similar power numbers and a stock idle.

the stage II will rotate the earth, with those same great street manners!!

my daily driver is a buick turbo, and it does really well for a bent 6 buford.

the turbo tech is where it's at!!!

[RiceEatingZR1]

Holy Cow! so those numbers were from a Stage I with stock Compression. any update on the Stage II?

[ZROne]

Ron, do you know if they are going to integrate with existing 368's or will SGC be doing these only on their own builds?

Chris
1994 ZR1 (Yellow)

[rkreigh]

engine will be redone with low compression pistons but a 368 would save the bucks on liners/rods, ect..

I have a pristine rotating assembly from my stock 95 lt5 *lpe take out parts from my original car* cool stuff

I believe it will take some time to sort all this out as these projects take alot of r&d

great to see SGC doing this stuff. I think a 390 TT should be in my future but it's a way out. gotta wear out this stroker first.

[Kevin]

Give it to me Ron.....I'll ware it out during my 45 mile round trip commute.

[zr11990broken]

Hy guys I decided to see what you are talking about over here. I like the babes section. I wish my wife looked like that but I bet shed be a real pain in the butt if she did and I couldnt afford her anyway. Back to the subject, Bill Kirchhoffer told me he built a S/C lt5 talk to him about it.

[cuisinartvette]

That's a real healthy torque curve! I can only imagine how it must feel to be sucked through the back of the seat! Who's going to be first?
