I see the excuses...but I don't see the et. Am I missing something?
You are missing the 112 mph trap speeds with 5 psi. Not bad. If you want to really gauge h.p., look at the mph over E.T. Especially if he is running stock susp and stock tires..

those do like normal stock power numbers...my 93 made 264/300 and i had a 2400 stall as my only mod.

my bad.......since our cars were rated 275hp stock, i figured theyd dyno around 250ish rwhp.

Wow you guys are a little testy with your sts aren't ya? FWIW...I don't care if it performs or not. Someone asked simply for an ET and I didn't see ET and I was genuinely curious as to what it could have been.

112 out of 5psi is awesome especially considering that 5psi is prolly not in the optimum efficiency range for the turbo...I was just asking for an ET...geesh!

Don't sweat it... The STS concept has been flogged on the Utah Board, Florida Board, and several other boards. It has been up here periodically but the big thread was removed. Don't take it personal, the STS guys have been beaten up for the last 6 months.

Sit back and enjoy the game... go Carolina... love them underdogs!!!

5psi is right in the turbo's efficiency range (76% i believe)

Make sense now? Or do you want him to give you a number so you can say, "See, I told you so. That kit is garbage. Look at the numbers is produces."? All while forgetting to notice his 60' time, and forgetting that he mentioned QUITE CLEARLY that he DID NOT launch well.

Anybody notice his last sentence? No problems with the system since install.
:crickets chirping:

Good numbers, Luke. I'm looking forward to what happens when you get it tuned. Keep us updated. I for one want to know because I'm looking forward to the same type of setup.
if that is in fact the case,the mph numbers arent totally true due to traction/tire spin. interesting numbers though from an interesting setup. just dunno if it would do what im looking for when i swap to FI from the bottle......

That may be true, but for how long? You could bolt up 2 T3 60 trim turbo's to an LT1 and run them at 15 psi, They will run thru the peak efficiency range as well, for only for the first few thousand RPM, then will drop off the chart.

I'd be willing to bet this happens with the STS as well with only 1 smaller turbo.

if i did my calculations correctly, its at the 76% efficiency at redline.

I dont understand while the system is knocked so much! What a society of ignorant people afraid of change. If yall would think before you opened your mouth and not just look at the pictures and go "Oh my goodness the pipe is so long, thats stupid it will never work". The idea is ingenious and yes it does work, could it be better? The answer is yes. Ceramic Coating on the exhaust would help and fins to increase the surface area on the intake tube would help cool the intake charge, but with the methanol injection this isnt as necessary. The kit is awesome, it delievers on a stock car, the methanol injection makes it safer on the motor, and it has massive potential with increased boost, different turbo, fuel, ignition, tunning, etc. Next time someone knocks it, please do so like you are an educated person. Read everything about it, analyze its downfalls and strong points, etc, etc, dont just open your mouth. It is so anoying and it just makes you look stupid.

for me, its because the company was using Gtech numbers instead of real numbers when they started trying to impress people..........that led a lot me to be skeptical of its real world performance. i could care less that its a "different" design........i just dont like seeing someone quoting Gtech crap.

so far, i havent seen any REAL world numbers on the stock motor that impress me. 409hp and 447tq would be acceptable, if it wasnt for the fact that hes having to spray methanol to get that number. id like to see those type of numbers WITHOUT the methanol.

Hasn’t G-Tech been proven to be quite accurate on some of its readings?
