GTM Stage 2 Supercharger Preliminary Testing Results

SAM@GTM

I was hopping that you got more out of what i have posted earlier. but to simplify things the less power and boost you are making the less tear and ware you engine is taking.

Well thats pretty much sums it up for me. I didn't read the whole thread call me lazy! I'm looking to get a supercharger about this time next year. I haven't found any single turbo kits, and the TT kit brings the temps way to high for me especially if its my daily driver. So I'll probably run 9psi on commutes 10psi when I get on it.

You should read that post... it is very informative. The amount of PSI isn't that big of a factor compared to what Sam posted.

Sam, that was a lot of good info and greatly appreciated. It makes me wonder because I really have no idea what my true IAT's are, could be really hurting my reliability, but we didnt really see any knocking on the dyno. Thanks for taking the time to make the illustrations and to post the pictures of the rods. Also the bit about the peak cyl pressures at peak torque are good to know and makes me feel a bit better about turning up the heat. At the same time it's kinda scary that Miami Summer is coming and Stillen never showed info on the IAT's after the cooler. Wish they would chime in and give us some info.

Much appreciated.

This is what you need PLX Devices Inc. - Single Gauges, Wideband Air Fuel Ratio, Air Intake Temperature, Exhaust Gas Temperature, Vacuum/Boost, Oil Pressure, Fluid Temperature

Scroll down to the Air Intake Gauge.

Good post SAM I think its a good thing that you take time out to show other members.

^I've learned more in that one post than me reading the other threads of people just yapping away.

Good stuff, Sam!

I believe Sam made a post similar in another thread. I don't remember which it was, but he explained the stain that F/I motors see and endure. This seems to be a much more detailed version which also displayed a pretty good apples to apples comparison. Great job again Sam.

BTW I love how he shows the Stage 2 TT vs SC.

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!
