debating boost.

[tbird31]

One of my best friends has a 99 GT with a built motor and Novi 2k. He's making in the 500s...his car is awesome. Truely a beast car. Granted I've only had the car together for a little while, and I built it to be N/A, but being around boosted cars has given me the itch.

Now, I have all supporting mods. I have a CC503 cam and 11.3:1 compression. I know that boosted motors like low compression as opposed to high. I'm completely new to the game here. I'd like to run a centrifugal S/C. A good friend of mine, Alvin, used to run a T-trim and he made 500s as well. Granted I believe he had a custom cam and some head work.

What would I need to get off the ground and prepare my motor to run a S/C somewhat efficiently. Basically this thread is about knowledge, to let me know if I truely can boost the motor I have without going back into it, which is what i really DON'T want to do. If so, then I'll put this idea on the shelf with many others...haha.

If your engine is not forged, then I would really stay away from boosting. Your going to want to boost it alot (higher boost opposed to lower) because lets be honest, you wont want to stay low boost for long. With a CR that high you can run into trouble with even moderate boost. Sure theres a safe way to do it with any setup, but if your going to be boosting it dont you want it setup perfectly for that?

Plus if it does get taken too far and something pops, all that H/C work you did could be at risk. It most likely will survive, but you never know. Its really up to you, but I dont think I would knowing I had all that $$ into it and its not really prepared for boost.

with 11.3:1 compression you might want to look more into N2O than boost. you wont be able to run that much boost with that high compression

[Fixxer99TA]

Yes, N20 would be a much better option.

Would yield about the same power when setup correctly also (obviously depends on how much boost your running on the charger, but you know what I mean).

Not to mention it will be thousands of dollars cheaper to run/setup initially.

That good friend....did he happen to be running that T-Trim on a 93 Forumula??? Just wondering if this is the same Alvin that I know.

Frankly, with a 11.3:1 static compression ratio, these guys are right. It's a bit much for boost. I would NOT do it. If you're wanting to boost the motor, plan on a fresh go-through, a bit lower compression, and a LOT of money as going FI is not a cheap endeavor.

haha...maybe...yea. That car was rediculous. He should've never taken it apart it was awesome. Basically his setup is what I'm thinking of.

Honestly I already have a N2O system waiting to be put on the car but I guess I'm just wanting a more, all the time power, sort of deal. Like I said though this thread is just gathering info. The more studying I do the more I'll be able to make the decision. The motor's coming out next summer anyways so perhaps I'll just spray it till then.

Plans next summer will either be FI or H/C LS1 with future plans for a roots blower. We'll see what the future yeilds...lol

Yeah, he had that thing dialed in quite nicely. The Eaton was a nice touch when it was on there though. Honestly, if you want to duplicate his setup, talk to him. He KNOWS WTF he's talking about with these cars. I've worked with him for a long time with the 93 stuff and he's never ceased to amaze me.

Too much compression for boost, I would stick witht the spray on that setup!

[Ponyhntr]

Listen to these guys... once you lower the compression with some forged slugs-then you can boost it! :D

Not only boost it, but boost it until your crazy hearts content. And you wont have to worry all the time where your pistons are :D

[KissMyWhtSS]

deff lower your compression before you boost it.

[Lcvette]

My question would be bwhat is inside the motor as far as parts? is it a stocker with some higher compression pistons? or is it a forged crank/rods/pistons?

if the latter, you can always swap pistons to a dished piston unless you went 6" rod and a stroker crank. give some more information.

if it were me though I think I would look into RealQuick turbo setup... if you think you like riding in a blown V8, you should definately yank a ride in a turboed car.. I own both and to my personal taste there is no comparison. my blower car makes 511rwhp with a P1SC on a 9.8scr budget 355ci LT1. nothing too fancy about it stock ported heads with a baby 219/219 .525 .525 112 cam.. not ideal but it does ok for 10psi.


turbos are the new hotness..lol

motor has SCAT rods and SpeedPro pistons, the rods are forged I believe but the pistons are hyperutectic. I bought the block used from a friend with low miles. They are flat top pistons.

I think I've decided to spray the car for now while I try to decide whether to go route A or route B.

Route A:
Forged 383ci
P/P heads
custom cam
low compression for boost
1.) Eaton (like Alvins OLD setup)
2.) centrifugal S/C setup

Route B:
LS1
heads/cam
eventually maggie/kenne bell :secret:

[Grr]

or you could buy my complete blower setup for $3k! lol, honestly im a turbo guy, but this car is way too much fun with the blower

[SS#1230]

without forged pistons, dont even think about it.

im running hyp. pistons at the stock 10.5 comp ratio and im waiting for a piston to break. then im gonna go to 9.0 with forged pistons then turn the boost up (if i dont do the rebuild before).

at 5psi im still hangin tough....
