Just wondering if it's worth supercharging a V8, and would you get much of a power increase from it?



It's a HSV GTO

Red goes fast.

Black goes the fastest.

Well think about this for a bit, of course your going to get more power. But depends on the cost if its worth it. You might be better off just working the LS1, they have a lot in them. Despite what a lot of people say. Or you could turbo it?

i would personally twin turbo it and considering the cost of this car it would probley be in the budget. my therory is supercharger is too boring and isnt really adjustable ie. its a bitch to change boost!!

single turbo is not good for v8s and v configurated engines for that matter due to exhaust manifolds having to be hugely wrapped around etc usually under the engine and to one side!! this also puts bank back pressure out!!. it also looks messy. twin turbo its a win win situation. a turbo on both sides(room permitting) equal back pressure on banks, more linear power band, and looks unbeliveble. personally i wouldnt do it too the engine unless you beef up the internals. lets just remember that holden had to fully rebuild heaps of these engines due to oil consumption!!! but i think gto being 300kw twin turboing it would be some where round 500kw but i think you would be looking at over 10k. As you can see i can write alot of shit about nothing and i just keep going and going and goin.

Hmmm, sounds like a mean car, btw the GTO is 255KW the GTS was 300kW.



Would supercharger would last alot longer on the engine, (what i mean is a TT would wear it big time wouldn't it)



this car ain't cheap so i want it to last.



What about a Super and a turbo? tongue.gif

I agree with posty, blowing the gen3 is the way to go. First I'd be going to chiptorque and getting them to chip it, set of headers won't go astray either.

Dont go twincharging, the computer to run it costs about $20-25 000, just isnt cost effective.

ill get some photos tonite of what we are doing to the old mans car, its not supercharging but its still going o make 450 hp at the flywheel normally aspirated,





speak to BOB ROMANO at mansfeild he knows his shit, but if u supercharge it get a vortech blower, bore it out port polish etc and get a motech cpu, then u will haul ass.



he also does good wrx' as well

whats this bull shit bout turbos wearing your engine hell bad?

done properly whats the difference from somthin like a 200sx?

you would drop the compression to run safe and being twin turbo isnt as much stess as single turbo either cause its not a sudden powerband! ohhh and is it auto or manual cause if its auto forget super or turbochargin it because it wont be too long before the auto will start slippin and melt

Well atm it's auto, but when im rich or something i would like it manualed, maybe i'll just sell a few kidneys.



Not mine tongue.gif

Lemme guess i need to win the lotto to be able to afford a auto/manuel conversion?



Would i really need it that bad if i was to supercharge it though?



Had an XU6 auto, that was fine, but it was also really low boost. (as are most stock blowers)

My uncles got a Silver one and is getting a V8 supercar exhaust

Bosch top of the line stuff, its absoulty nuts what it can do tho', if its controlled by the computer you can play with it. I mean if you have the money to waste go for it.

Dude ill get ya a number for Colin Loyde, owner of headsence, talk to him he knows fuckin shit loads more than what i do , and he builds performance cars. To be honest, i would supacharge it, 1 its more direct and, its instant, with no lag like turbos get, but that come down to preferance



and cams the pc to run the twin turbo think is a motech and its 3800 the old man has one on order for his car.



im still tryin to get all the pics ill have em tommorow





how much u lookin to be spending ?

No idea yet.

Not even sure if i can get insuranec on it yet

atm its all in bits, but u will get the gist



there is a guy also at lawnton who has made a slide throttle body its a sweet set up, but its exy, but u will make heaps of hp at the wheels im talkin FN HEAPS



ill get more details as well

Post #28

yea man it will cost u like 10g 2 blo it but u gotta watch the engine internals if u giv it a hammerin alot, and u get like 40% power increase

Turbos wont have "lag" on a V8, damn things will be almost on boost just at idle.



Supercharging is more bogan, also a lot cheaper cause there is fuck-all pipework to do on a supercharged engine, whereas a Turbo V8 is almost definately going to be a twin turbo configuration so you get the cost of 2 turbos as well as a SHITLOAD of pipework.



Turbo (or TT) is gonna give a LOT more power than a supercharger, but will also cost alot more. Supercharging will give more progressive power, (eg: as revs increase, power increases in a linear fashion) as opposed to turbos which will give you a massive kick in the pants midway (eg: exponentional(?) power increase).



Turbo will give more power up high, supercharger will give more down low.



Get a TT setup, you'll be the ducks nuts. But since you aint even got the car yet .....

well, let me get out the big guns tongue.gif hehe



Mr krawler, tt is good but a supercharged v8 will kcik ass, there is a guy ( DCIEVE ) who is doing 700 hp at the wheels witha supercharger. i know what u think bout bogans tongue.gif u know what i think too.



i got bits n peices on shet about both ill dig it up scan it and post it biggrin.gif

Thats great, there are multiple TT V8 setups running 1000+HP.

For the street a TT V8 would be better. As you can drive it off boost, and change the boost with ease.

... You can also get a clutch on the superchargers that works like an A/C clutch (eg: flick a button, you get boost)

But then whats the point of that if we already decided twin turboes are better... tongue.gif

I say turbos are better, but its always good to compare the good and bad points of the two sides of any arguement.



In this case I'd say supercharge or turbo it, who cares, cause the guy doesnt even have the car so its just a make-believe fantasy atm.
