What is you RPM at WOT on a SBC?
 

What are you guys running rpm wise on your sbc 5.7 at WOT?

Fixx
 

average 5800, on the high side 6200 but mine is far from stock...

Stock 6.2s 5200 but I need perfect conditions for that mostly WOT is 5100.

On our old 272 with 383's was 5700 rpm

Stock 6.2's turning labbed 28" pitch Bravo 4-blades.

Mines a 406 pretty mild hydraulic roller idles like a kitten

It can spin faster but it signs off at just under 6.
(In my experience accessories dont like to spin much faster than that anyway.)

Makes 500HP and about 515Ft lb.
Ive spun a 4 blade 26 61-6200
It'll shoot this little tunnel across a lake or river at just a hair over 90 and handles like slot car-

About 5300 WOT for me.. roller cam ZZ430's...used to run 5800 on another setup but seemed abusive for long periods of time..so I repropped :eek:

406 solid roller. Usually run 4800-5000. Have turned 6200 with a 27p Hyrdo QIV but let out of it. Made 594hp at 6300rpm 540 tq at 5400rpm.

I have to ask:grinser010:

Is everyone running alpha drives?

Im running TRS drives and only turn up to about 4500 at WOT. I thought it should be higher more like around 5000. Looks like some prop work is in the future.
