Ok so we have tested the inlet change and the results were interesting. We did 30 runs changing air bleeds, timing, lash and a cool can.
The Air Gap performed well and the 830HP carb was right on target, we ended up with a 20rwhp increase and 41rwfp of torque. Here's what happened.

Temperature was 24.2c, Humidity 80% and pressure 1017.0hpa
Playing with the air bleeds and timing yielded the best result, tightening the lash from 32/28 to 28/24 we lost 7.4rwhp no mater what we changed. The cool can was good for 4.1rwhp which surprised me as I didn't think it would do much.

End result was 335.9rwhp and just on 500rwfp of torque both of which was disapointing. The power curve move considerable as it now came's in a lot earlier at 2500rpm and stays well into the mid 5000rpm, with peak power at 4200rpm which is a big improvement.

I still have a fuel pressure problem in the upper rpm range, as the carb is emptying the float bowls, we increased the float level until it flooded and then backed it off until it run and the power stayed longer every time we did this until the pump couldn't keep up.

I have a Carter 130gph mechanical pump with no regulater and is a deadhead system, now there could be a diaphragm problem in the pump or I hust might need an electric pump and reg.
What do you think?
