Why would you have gone with T72 over the T66, why not run smaller injectors like 720's?iturk said:BLK-SP64,
Thanks man, I should have dynoed a long time ago. You guys are right...I have a small turbo for the injectors. If I had to do it over again I would have probably gone with a T-72 and maybe a 272 on the exhaust side.
Yes I do have a lightened flywheel. Guess that should be good for 10-15 rwhp or so. So what is the outer limits for a T66 (w/o cams) at 28 psi I'd imagine 650 rwhp, about the same as an SP-63? I don't have a UD pulley though.
The correction factor was ~5% according to AAM. It was around 55 degrees and I am only ~300ft or so above sea level.
Now I just need to beat that damn LPE-C5TT. We ran again last month again before I was tuned but I was at 1.7 bar on cam2 116 octane and I was only 1/2 car behind from 10-100mph.
Will post the dyno this week.

I'm just asking this to learn...
You aren't happy with the numbers the T66 put down, and would be willing to have extra lag with the T72 which is equivalent to the size of a T88, right?
iturk said:I went with bigger injectors in case I wanted to upgrade to a larger turbo. I still am not used to the lag. At 3K rpms my car makes only 100 rwhp, I made 200 rwhp in my BPU. I have such a short powerband of 5-6.5K rpms where rwhp goes from 480 to 585.
In need to get the GForce...what will that let me tack to? 7.6 or 8K rpms? What does the Gforce do besides removing the 7K rpm fuel cut?
So the T72 is bigger than the T88? Is the 72 the largest you will usually find on the Supra?
