Turbo vs. Supercharger

[JL8Jeff]

If he's just looking to pick up 100 hp then a supercharger is the way to go. He could even get away with the Powerdyne setup to keep costs as low as possible. But I would look into the Powerdyne, ATI or Vortech superchargers. They will range anywhere from $3000-$5500 with the ATI and Vortech being more expensive but also giving more room for expansion in the future. If the car won't be driven like a daily driver then the rear mount turbo is still not a bad idea. I just don't like all that extra stuff hanging on the bottom of the car.

The guys in the shop there do some nice work, I've gotten the chance to inspect one of their TT Z06's up close while they were fabricating the mounts for the intercooler. After past experiences, I just wouldn't let them tune the car....

this car is a daily driver for now but i wanna be able to make an even bigger point on the street than i do now. I also wanna be able to take it to either E-town or Island and run some nice numbers . im still undecided on which set up i wanna go with :-/

[Brando56894]

if you wanna do that then id say go with a turbo and get an electronic boost controller. you could run 3 psi on the street and 10 at the track (that is obviously if your car/engine is setup for it but u get the point)

Jakes list of things you need to replace is a bit on the "cover your ass" side. You dont need everything on that list, but you definitly need the fuel system stuff. more air going into the motor means you'll need more fuel.

If this is just a street car that will see the track every now and then, I'd go with a centrifugal supercharger. There is nothing wrong with either power adder when set up properly, but the supercharger will be a simpler install (dont have to change exhaust setup amongst other things).

Turbos are better overall than superchargers for a ton of reasons....but definitly not cost . Turbos are more tune-able and will make more power in a max effort motor (ever notice that turbo cars have the most handicaps in bracket racing?), but thats only gonna happen in a race car, not a street car.

either way you decide to go, you're gonna love it! good luck.

Okay, not like it matters, and I dont read all of the posts, cuz I dont have the patience for that ****, but, my opinion, is, your eventually going to need to build up your bottom end, 100hp, isn't that much when talking boost, this is why I say eventually, the stock bottom end can't handle large amounts of boost for too long. Turbo is always the way to go, they are more efficient. They take exhaust gases, and put them to use, superchargers rob power, in order to make power. I've seen a couple turbo cars turning some serious numbers at the track, that were completly spooled up, at 2500 rpm...This is possible with small to mid size turbos, I've always been a TT kinda guy as well...THis way you dont have to worry about turbo lag, I know i guy that had a twin turbo 93 rx7 when i lived in Japan...he then "upgraded" to a Large 90mm turbo...He actaully saw a drop in his drag times...and no, the fact that i'm talking rotory motor, doen'st have anything to do with it...just my two cents...as usual...

You might want to check one of the magazines like Car Craft,Hot Rod,or Super Chevy. Iremember reading an article about a new type of supercharger that has the benefits of both without the drawbacks. I believe the company is called Rotrex. Sorry I can't remember which mag but it was published within the last year.

he'd be lucky if he could spool up a powerstroke turbo, let alone an international turbo

[NJLT1SS]

My first choice would be a turbo kit from PTK (mounts under the hood), followed by a centrifical supercharger. I have seen 2 F-Bodys with the rear mount turbo setup, and I think its a horrible setup. The pipes hang really low, pressure tubing runs under the axle, its just really ghetto lookin to me.

Don't doubt the power!!! I already have the specs...

[PureSpeed]

the rotrex is a centrifugal supercharger thats fairly small but will provide sufficient amounts of boost. only downside is that you dont get the traditional supercharger "whine" See i wanna be able to pull up next to a cobra and when they rev at me i wanna rev back and make them cry

TTP has done several STS installs and tuned for them as well. they also happen to be sponsors of the club

OOOOHHHHH! well if thats what you're going for, I think Kenne Bell makes blowers for LSX motors now

[rgaynor85]

but they dont fit under an fbodys hood that ledge over 1/2 the motor prevents it only the vettes use them magnacharger makes them to

[PureSpeed]

mmmmm kenne bell twin screw..haha yea thats what i origionally wanted but i read in this thread that kenne bell doesnt make one for and ls1 :/ And if they do make a blower for the ls1 and it doesnt fit under the hood...then ill just get a massive hood scoop haha

[rgaynor85]

its not the hood thats the problem its that large ledge than comes out over our engine.

They make a blower for the LSx motors, but it won't fit under the F-Body cowl.

[Brando56894]

bah who needs a cowl anyway??

[Savage_Messiah]

Brando proves himself "slow" once again

[rgaynor85]

oh im used to callin a cowl a hood not that thing but ok

[Savage_Messiah]

technically that area is referred to as the cowl... cowl hoods are actually called, IIRC, cowl induction hoods due to the opening being at the cowl...
