benifits of super vs turbo

[mysweetvt]

I have been quoted $9500 for a complete turbo setup for my vt calais,which would be quite unique, but i know you can get superchargers for much cheaper than this, what are the benifits of each against eachother? im looking for power but most of all i want it to last a long time and not need checking up on all the time, and to handle some curry down the quater mile. My calais is a 3.8 v6. Thanks rohan :bang:

Basically the turbo will develop more power, the supercharger will develop it early. So the turbo should be faster in a straight line, however it you put that much cash into a supercharged v6 it would be pretty quick. I would like at a different model with a ls1 for that amount before pouring cash into a normal ecotec.

The normal ecotec is a l36 and the supercharged engine is a l67. There are a fair amount of different components in the two engines. Including fuel delivery etc. The l36 is meant to be able to handle a supercharged setup but once you increase boost the l36 is not your best option. One of the differences is the compression ratio, which apparently needs to be different for forced induction.

Have a read over the fit website as they have a heap of info on the whole deal.

In particular read this, Forced Induction Technologies - Australia's V6 Supercharged Specialists

super - no lag, but used engine power to drive it. cheeper

turbo - lag. no powerloss to run turbo. deerer.

insurance may also be a bit unhappy with having a turbo commodore.

if you do turbo it, PLEASE dont put a gay blowoff valve on it, nothing is funnier than a vl turbo phhhhhhhsssssssh tu tu tu

go the turbo mate nufin more exciting then seeing a v6 turbo commdoore go down the quarter , everyone has a cammed ls1 that runs 12 and everyone has l67's with high boost and and intercolled but how often do u see a turbo ecotec ? , i rkeon the 9500 is well worth it and makes your car alot more original

9500??? wow thats steep, do some research and turbo it yourself, well not yourself, get brackets and pipes made buy and intercooler and a decent turbo wastegate and manifold and you will be cruising in parts i reckon it would set you back 4k for a real decent setup. and about 800 for someone too put it on properly.

if u want ur car 2 last a long time dont get either stick 2 how it is

you can have my setup for 5g, and includes everything cept sump and tune. including 3" exhaust, polished aluminium pipework, ceramic coated manifolds and turbo housing. polished comp cover. reversed plenum, 32lb injectors. i also have a larger comp cover and wheel just hasnt been fitted. with larger comp cover and larger injectors would easily see 220rwkw. boost pulls hard and full at 3000rpm running 8psi.

Wouldn't it be better if you just drop a V8 in there??
I mean if you are just looking for more power.

If you want your car to be quite unique, then turbo is good but you need to strengthen your engine's internals before you chuck the turbo on.

 

[holden007]

Turbo will cause you trouble in the long run, thats why the engine should be rebuilt (strengthened).

You want something in the long run with power, go V8 (LS1+) as AttaBoy as mentioned.

Has power on the spot, has standard components so it doesnt cost an arm and leg to service (cost wise) and you'll have that nice crisp V8 sound (i.e with exhaust).

i dunno where you people are getting the idea of lag, in most cases the v6's are using a T3/T4 which is very daily driveable and come to the line to race, bring the revs up to 2500rpm and bang your gone and even on the highway overtaking there is no lag, with my 5 speed i knock it back to 4th before i overtake and just before i step out its back to 3rd and i'm around the car quicker then you know it.

so with a 2500rpm stally for a auto there would be pretty well no lag off the line. and you can run usually up to 7-9psi before you will look at doing the internals
