I agree. It is just a quick and dirty gauge that cannot substitute track time or a dyno. But if you're in a pinch, it helps. For preliminary data it should be ok, but for solid proof... I agree with you. At the point that theories are backed and become as statements, then they should use valid/standardized forms of measure.

Besides, a quick download of any car in a dyno is pretty cool advertising

 

Why not? Jordon ran 130 traps with ~500 rwhp in his car. I don't think it was stripped either. I'd guess around 3500 lbs. My friends 4000+ lb. mustang vert went 125 killing the tires to the 1/8th, and it dyno'd ~550. What I've usually seen on G-techs is anywhere from 5 - 8 mph high on trap speed, so lets say it ran 124 - 127, sounds dead on, since it takes a bit more power for the same mph on a boosted setup from what I've seen. If the car was a stipped down hardtop, it could weight in less than 3300, 100 lb driver, there ya go, right near 132 traps.

 

FYI, i ran that 130mph traps on a VERY good weather day :-D

 

I raced the STS turbo LS1 in my vette. My car goes pretty consistent 12.6 at 110 NA with a density elevation that is usually 7k. At sea level, my car trapped 121 pretty regular. Stock LS1 cars here are lucky too break ino the 13's.

I killed the car off the line (IRS) and figured he'd have no chance in hell of running me down. At about 100 he came trucking by me pretty good. I would say the LS1 STS car would go mid 12's at 115 or so. That's a 1.5 second improvement over stock. At sea level, it would be interesting to see what an STS car would do.

The owner of the STS car too me for a short ride after the race. I haven't ridden in a conventional turbo LS1, but the lag didn't seem that bad. In first gear, from a 5 mph punch, he would see full boost by 3300 or so. As he shifted (its a 6 speed), it would take a split second for the boost to come back, but nothing too drastic. I doubt you could snap your fingers in the length of time it took for the boost to come back between gear changes. We never did any punches form a high RPM in a higher gear (like 65 in third) but he said the boost comes on real fast in a higher gear that puts more load on the engine.

Anyway, the cars are pretty quick for the cost of the kit.

What if you were to run some cooling fins down the length of the charge pipe? Or header wrap the exhaust? there are lots of things that "could" be done to improve this kit. It hasn't been out long enough, tested enough, or put on enough cars for anyone to say its good or bad.

 

Random Thought...

Since the system is located in the back, it will create more exhaust back pressure (2.5-3:1 ratio on the Exhaust-To-Intake).

Air under pressure creates heat.

If the air in the exhaust is under pressure, then heat is induced... which will sustain more heat than an open exhaust.

In other words, if a typical exhaust temp is 1800 at the Exhaust Valve and 1200 at the tailpipe... The backpressure would induce some heat and perhaps a temp of 1500 is possible (relative with the variables of ceramic coatings and the turbine housing orifice).

Even if the temps dropped down to 1400 that is still not as low as 1200...

Again, it is an interesting concept but I would like to run some temp and backpressure tests on this system.
