180 track car project

[Noobrider]

well had it on the rolling road last weekend and I was pleased but dissappointed at the same time.

Having removed the balance valve from the plenum, I was pleased with the torque curve, which considering it was done on a power run day with a wide variety of cars on the rollers, the operator commented that this was the run of the day with the best curve and consistency over the two runs.

Dissappointing though that so many horses have escaped despite decatting and inner wing filter...down to 166 bhp (165.9) with 156 ft/lb torque.

there was a definate pick up at 4250 as the power valves opened so I am going to jam oped the power valve and take it back on the rollers to see what effect that has on torque curves

if the torque is at the wheels, that is very good - check tho, it could be fly.

165bhp at the wheels is good also for a car with std cams.

can you post up the graph? might not be all that bad

balance usually opens at 2980rpm, so the only losses (assuming all else works) will be below that - on track, you'll never be that low in revs anyway.
