I've seen many a dyno done with a torque power menifold. They all fell over around 6000rpm. If your running 2V heads that cam will fall over around 6300-6800rpm. No point using a manifold thats going to fall over before the cam.
If you want a dyno queen with bragging rights of peak power, dont use the Torque Power.
But in realitiy the 200 or 300rpm you loose at the top, will well and truley be made up and more, with the ultra high torque you made at low and mid range.
What would be a great test is a 12 second car with a TFC or FW and do a 1/4 mile run, then swap to the Torque Power the same day and do some more runs. I think people would be surprised of the results.
I know someone that has tested one. 11.4 no torque power 11.8/11.9 with. Remove the torque power and back to 11.4's.
What happened due to it falling over with the gearing it had. He simply ran out of rpm. doh!
Yeah, you are probably right. The set up still favours the hirise. Maybe adjusting gears, stally and tune to be optimum for the TP too would make it fairer. We'll just have to wait for some keen guys to try.
(brenx, what manifold did they use against the TP?)
