GTM Stage 2 Supercharger Preliminary Testing Results

Dzel · 05-24-2011, 12:53 PM

Thanks guys for the eye opener. I am for sure leaning towards a SC now.

Shouldn't the Main concern be about Compression in PSI, and not necessarily the amount in boost?

11:1 at 10 lbs of boost = ?? PSI

VS.

9.5:1 at 18 lbs of boost = ?? PSI

I don't think it's the about of boost, but the amount of compression in PSI that blows up motors.

I'll be running a 10:1 compression as recommended by Sam, 11:1 is not the safest IMO

Great to get a basic understanding of how the Supercharger version seems to make more sense than Turbo version.

I've always wondered why Lotus opted for Supercharged 1.8 & 3.5 liter Toyota units (apart from the throttle response issue). They probably came to similar conclusions.

Please everyone get SC kits so we Turbo guys can remain a rare breed!

NewYorkJon34 · 05-24-2011, 08:53 PM

It all comes down to personal preference really & how much your willing to spend.

KaienZ34 · 05-24-2011, 09:17 PM

If money was no issue, it would be TT for me.

My only concern with the TT setup is the temps it brings the motors up to. My car is a daily driver so you can see my cocern. I am keeping track of the single Turbp that 98intique is perfecting. Might go that way depends on the results in the next year.

I have logged over 8k daily driven stage 2 boosted TT miles in Texas weather with not one issue. I have currently retired her for a while since I have another car to drive and simply cause I have well over 35k invested etc. As far as temps go, I can run the sh!t out of it with out any oil temp issues. It is a street machine only. Not into the whole "track" biz, so no track data to hand out. However I can speak on the fact I can rip she sh!t out of her time and time again in the Texas heat and sustain nice temps no prob. I just got a new DSLR and I am working on some vids for you guys to drool on maybe I will capture oil temps for some of you too.

So yes people buy all the SC's up! That way Turbo guys can stay exclusive a little while longer

What your saying will never happen people will always go turbo first if they can.Most of the time it comes down to the cost /simple install of a supercharger.

By the way what kind of flavor hatorade are you drinking

KillerBee370 · 05-25-2011, 02:00 AM

I've got no problem going supercharger. I drove a turbo car... one that was stock WITH a turbo. Z's are a N/A engine and as such I will have to worry a lot less with fussy maintanence in the long run.

You turboheads can remain exclusive... it's all good.

My concern is also the shock that you get on your internals from a TT kit. If they had a perfected single I would jump all over it. Sam made that very clear earlier. That's a big factor to think about when your gonna run stock internals for a bit.

Just letting everyone know, We are in production for IAT Gauge and Intercooler In & Out Temp Gauge. Just sayin, for all you worry bees!

Good info sam. As far as running a single turbo on the 3.7l motor, With proper tunning the TQ curve can be less aggressive, input?
