has any body used a f-246 with the torque power manifold or any similiar cam like the previous thead were they used a smaller cam and any known results or any dyno results

I seen a article in a performance ford magazine about these manifolds. They seem to be a very good manifold. If i am right i think the crane f246 cam has a rev range of 3800-7000 rpm.

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.

Use a TFC or Funnel Web. There is a new manifold out you may want to consider? http://www.network54.com/Forum/11941...PLANE+MANIFOLD

I wonder how a F238 and torquepower manifold (port matched) with 4V heads would go? both cam and manifold seem to be limited to 6000 rpm?

I'd imaging it'd work well. F238's seem to run out @ 6300rpm ish.

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.

[edit]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?)

brenx

Can't remember off hand but it was a single plane.

Use TFC if you can, i had stock 4v f-246, a holley strip dominator and a rooted bottom end, it made 226rwkw.
