Turbo or Supercharger..... Hi folks, my name is chris. (easytoremember from clubgp and many other forums)
I did an L67swap into my 95 gp, and built it up to run 12.3 with stock heads an no ic.... then added an ic, and ported heads, and popped two pistons (yea messy)
Anyway, I am here to start research for my next project.
with the grand prixs, the power hitters are taking off the supercharger and going turbo...
going v8, someone said supercharger over turbo..... thoughts? (ps i want about 1000 hp on the dyno and about 700 on the street)

Turbo is going to out do a supercharger pretty much every time... The power is linear and good. Also doesn't come at the cost of taking power from the motor. Stay turbo. When I had my 02 lightning people were putting holes in the motors at 500whp on the s/c but if they went turbo route they didn't see problems till about 600whp.

Finding a reliable source for a good F Body turbo kit can be a nightmare, and can land you in bankruptcy and in need of a good counselor. lol You will just have to check around, and be careful with your money. Bob

I had a CAS twin turbo kit on my LS1. I loved the power, didnt like the lag (my 4:10 gears didnt help) but ill say this, it was a pain in the *** to work on and theres alot of little stupid BS that goes on. and if you dont have a lift and the tools to work on a Turbo car I feel bad for you because the cost of labor to work on a turbo LS1 SUCKS!!!
I sold the TT kit to get outta debt. it cost alot more than I planned.

You should bone up on turbo engine combinations and speak in depth to engine builders that have built both turbo and belt driven blower combinations. The builders that measure fuel flow will educate you on BSFC numbers. Turbos often use more fuel per hp....this means their parasitic loss can be even higher than a comparable blower combo. Besides, there would be no parasitic loss if there was no power adder. You're missing nothing.

So what if you take two engines that has the same cubes, cam, heads, intake, compression, etc. And then you put them on the dyno to make sure the make about the same hp. And then from there, one gets a centrif blower and the other gets a turbo of around the same flow capacity as the blower...At any given psi level, which do you THINK would make more power???And I know you said CAN be, but at what level? Im just curious to know, and I hate to compare them because its like comparing a windmill to a watermill...
turbos rule, superchargers drool. nuff said. Sure you have deal with potential overboost, nonlinear power and extra complication inckuding boost controllers and wastegates, there is nothing more street friendly than a good turbo. add a proper boost controller and a bunch of tuning work and you have a winner. OR bolt on a supercharger and go. dont know if I'd go across the country like that, but go... local.
