I think we are on two different wavelengths here, which is fine.
Here's an idea, why don't you completely remove the water/meth setup from your car, and then retune it for 93 pump only...and then redyno. After you see your new dyno numbers, let me know if you think it's the same as comparing ICs....
yea...you're missing my point...I never said compare WI to larger ICs. I meant compare Stock ICs to Larger ICs....since the larger ICs should lower IATs.

right!!
Stock IC vs large IC's = performance advantage
WI vs pump = performance advantage
Race Gas file vs pump file = performance advantage
Race slicks vs street tires = performance advantage.
The issue is how much of an advantage. And the article shows that it can be as much and possibly more than C16.

just face it your running a race file so what. nothing wrong with that at all. I'd rather run a WI race file than a C16 race file. WI burns cleaner better for the environment, keeps things cooler. To many benefits over C16.
I run a pump + WI file daily. Yes the tune can run more boost then just an OTS pump file and yes, it can run more timing. But my Race file runs more of both!
My car has 5 Bar FPR and k24/18g that's it, all pump gas. I beat the same 997tt with flash that Vince OP (GT28 w/meth) raced. He is not on the forum. We both pulled 4-5 cars easy. Yet the 997 tt flash is running 8 sec same as my car.
K24/18g with only a 5 bar FPR at 1 bar boost is equal to a K24/18g with injectors running 1.3 bar unless you run a race gas file (1.3 bar) and race gas.
We proved this by racing my car against Jasons car.Our cars are dead even. So we think the ECU pulls timing at high boost unless you are running race gas.
Now the GT28 car with Meth is a Tiptronic , so more transmission losses so the power is same as our k24/18g cars.
I dont think anyone here has answered one question...why is the GT28 Tiptronic car that made 530awhp still running 8sec 60-130?? There isnt much technique to running a tip car, every single time op starts from 20 mph and floors the car ...same results.
I think all k24/18g cars running pump gas are pretty much the same power wise and should run the same 60-130 with the same driver, same weather conditions, same location etc...There should not be statistically significant variances like we see here.
Yes if you run race gas, drag radials, 200 lbs weight reduction...the times will improve , but highly doubt there will be a 2 sec improvement. At this point , i dont really understand what the goal of these 60-130 times are ? cars are different , conditions are different. It gives us an absolute answer , not a good comparision tool.

Okay. Let's just agree to disagree. This is getting tiresome.
Ok guys...i did a calculation between my worse file(7,04sec) and my best file(6,32sec)on the 6,32 when the car reached 130mph it needed 282meters...ON THAT TIME(6,32SEC) on my worse run i run 275meters...(and had a speed of 124mph)so at a finish line of 282meters starting from 60mph,the faster will be 7meters in front,equals to almost 2 car lenghts...

interesting that the 24/18's did not benefit from the larger injectors. Definitely counter intuitive. I would for sure thought that there would have been a huge difference between the two. but then again inj duty cycles could be different etc. with the larger injectors you can flood the cylinders with more fuel to prevent knock and be able to increase boost.

I think the larger injectors increase your safety margin, that's it. Its not a power adder until you add octane and run high boost.
at some point i will do injectors when my clutch goes, Doing it all at same time saves labor

Thanks..now that would be possible. I can see some cars of same setup pulling 4 cars. Esp the one's running race gas, cold weather and weight reduction.

If you keep stock injectors with k24/18gs at boost levels over 1,0bar the duty cucle of the injectors is over 90%...So they do not flow properly and even...this might cause many troubles...so it is better to replace them with larges ones...for safety and for more power,when boost gets raised...So a properly tuned k24/18g with injectors is faster than any without them...
