well auto whenever they hit it its going to jump to 4500 and it will prolly be near 450 or more ft lbs and drop to around 400 at 7000

hp will be id guess 390 at 4500 and go up to about 425-425 at 6500 and drop to about 410 at 7100 or so

should be pretty close...flow numbers on the heads will help a lot

It should run strong as hell at the track if you have all the supporting mods. 10's shouldn't be that hard to hit. Your 3600 stall might be a litttle on the small side though.

well i got some numbers with DTD but since i don't have all my cam specs yet since i waiting for it to be ground I used the 847 with 1.5rrs i would have done it with 1.6rrs but didn't feel like doing the math.

power at FW cam to be 574 @7000 and 493@5000

considering at 25% drive train loss it would be

431 RWHP and 370 RWTQ.

tq looks a little low but it's just to give an example and seems like the hp would be pretty close

Mine are still waiting to go out i sent them and email to get some flow numbers. they average around 275-285 for there stg 2 depending on casting i also used the thread asking about everyones flow numbers to estimate.

Like i said its just estimated its not perfect or exact the cam is have is very different from the 847 so i really don't know what it will make but should be close.

if you want give me some info and i can put it in for ya. will need the cam card though deck height. piston to deck height gasket thickness chamber volume and head type average flow numbers vith valve size

508@6500 479@5000 flywheel hp thats with the cam I had in still using 1.5rr specs.

subtract about 25% for rwhp. it will show a little low though. I would say you will probably be around 400-410RWHP

you cam specs would be needed for a better estimate also i cant add bigger injectors or the EWP. so those are probably really off
