Which do you install on your GTO? I was talking with my friend last night and he said S/C all the way. What is your opinion on this matter?

 

[GTOdriver7]

i have not seen ANY turbo setups for the GTO. thus i could not really give a fair comparison
if you can show me some, then maybe i will vote

 

[desertgoat]

When my warranty runs out, I am driving my goat straight to Howie at Arrowhead and would tell him to install the best supercharger money can buy. Now all I need to do is to get to 72 mos/ 50 K miles as fast as could and I will have a goat that has 450+hp in it...

 

[Shocker]

I would say sc turbos I hear are harder to maintain.

 

[goatwrx]

turbos are a bit harder to maintain, and after spirited driving it is essential for most turbo equipped cars to cool down before they are shut off to stop the oil from baking, see turbo timer. Plus lag will be an issue with a turbo, all though with the V8 grunt of the 350 there won't be notical lag. But I still say supercharge it.

Man If I had the extra cash right now I would do the magnacharger and not think twice about it!! :burnout: :burnout: :burnout:

 

[Dbluegoat]

I am getting the magnacharger before xmas....turbos cost more too

PD blower for me

In Australia we have LS1s fitted with
- PD blowers
- centrifigal blowers
- single turbo
- twin turbo

The thing I like about the twin turbo applications I have seen is that you cannot see the turbos, and most cannot pick any change in the engine bay. Lift the hood on a blown motor and you can see it straight away.

Can you post any pictures of these setups?

are you talking about this one?

Thanks, any other pictures?

Twin Turbos. :secret:

 

[flyinlow]

V type engines are alot easier to put superchargers on than turbos. You almost have to do a twin turbo on a V engine, and now you're talking big bucks. The advantage is you can do alot of playing around with them.

That is not the reason to do twin turbos. Look at the Grand National, single turbo V6 engine. Reason to do twin turbos is to either stager them in a sequential order, one small to come in quicker (thus reducing the so called Turbo Lag) and a larger one that spools up later to produce more power. The other reason is to help modulate the power by runing two smaller turbos to spool up quicker rather than one larger turbo to make better midrange hp.

Look at all the HIGH horsepower street machines. Supras, Skylines, etc... The Higher Horsepowered machines are using a single HUGE Turbo to make power. Sure the PEAK numbers look great on the dyno, but have you seen the curves? YUCK.... peddle to the floor....nothing.....nothing.....nothing...HOLYSnikeys !!! Where as a dual turbo will give better midrange.

Its all about your end goal. Ease of maintainence and installation with decent gains - SC. Better gains with a little more installation pain SC with an intercooler. BEST gains will always be a turbo. Its more efficent in its flow giving better results. Look at the majority of setups between a turbo and a SC. The same PSI will not give you the same power from each. A turbo will usually have higher torque level and a flater torque curve then that of a SC.

BTW - The myth of turbo lag is virtually non existant today. Better turbine design and ball bearings have virtually eliminated this previously plaguing problems.

haha, yes we have all seen STi dyno curve.

very true.

are the fuel system and injector upgrades necessary while getting the magnacharger or can we just strap it on the stock motor and be ok?

I have seen some sites saying you can purchase and bolt it on however I wouldn't recomend that. It seems to get what you want out of the magnacharger a few more things need to be tweeked however I'm sure some other people will know more about it than I? :eek2:

 

[flyinlow]

Uh, top of the line Skylines and Supras are twin turbos and most of the modified ones I have seen in the magazines also stay twin turbo.

If turbo lag is non existent, how do you explain STi's torque curve, which looks like a mountain peak.

 

[JZ 97 SS 1500]

Lag is all a variable of cubes, and which turbo unit you use. With the right turbo on any motor, it will blow away a S/C.

BTW I vote for twins T's. How can you go wrong with this GTO/HSV.....
