Water/Methanol Injection CAN increase power if TUNED for it on a Dyno. I have personally seen over 10 cars with kits LOSE power, and in particular mid range torque with Water/Meth Injection kits before being tuned properly. John's car has not been tuned on a dyno for his kit yet, which is why it is probably hurting his mid range and top end at the moment. With tuning he will no doubt go 133mph+ and probably get down to a 10.5 or so.
Yes, meth injection can cause a loss in low power no tune cars. In high power cars with a tune it is not loosing power but adding tons of it. Unless you have a stupid tuner in which case they should not use it.

Why don't you guys start a new thread about quarter mile times? This thread is about road racing. Which is really what these cars were designed for.
I would guess that the 1/4 issue is that it gives an idea as to the power a car puts out. That is the only reason I reference it. But I agree that if we wanted drag cars we could just buy an old plymouth aspen or dart, stuff a big block crate motor and stick a supercharger on it and bam 9-10 second et's all day long.

Trojan: that's disappointing to hear from you. Are you committed to 200 pages or not?
Be nice, Chris...it is the holidays, after all...

That was a good one.

dude, meth injection is like running race gas. A car tuned on meth is like a car tuned on C16, except better because meth cools off the engine. Now that explains how the car ran what it did. I was actually thinking it was a freak car. lol
Actually our highest trap yet (129.5) came before we put the meth kit on the car. I've been dying to take it off the car but my mechanic insisted on it until we can get to a dyno a properly tune the car. (He wanted to make extra sure we avoided detonation.)
I can assure you, this meth kit IS robbing the car of torque.

Thanks for the info John. Just as I thought, without tuning the car on a dyno, you are using the Meth kit as a buffer to avoid detonation with a mailed in tune on your Cobb Accessport. This is seriously affecting your mid range and top end power. Keep us posted when you go to the dyno and get that GT-R tuned! I am sure your traps will go past 133mph easily with a good tune. It would be good to see a baseline dyno, and then what you ended up with just by actually tuning the ecu.
How does Meth injection work its way into a RING Time?
It's easy, man...
Methanol + hydrogen + carbon monoxide over a cobalt/iodine catalyst + heat/pressure = ethanol.
Nissan engineers + ethanol = 7:29

How does Meth injection work its way into a RING Time?
HAHAHA!! I think we can all come up to the conclusion that the ring times did not occur in as-delivered condition as much as several loyalists would love to believe. Too many tests out there to prove it. Common sense and physics cannot be defied by that much. Sure Nissan has a video with time, but videos don't show horsepower numbers. The car had to have been running higher-than-stock boost and the suspension had to have been tweaked just for the circuit with an appropriate set of tires.

Apparently when Suzuki uses Meth injection, his Ring times are 8-12 seconds faster. Some American drivers have unsuccessfully attempted to shave lap times using combustion/inhalation Meth technology, but the Asians have clearly shown that direct injection is more potent.
