Put down 309 @ 6174 rpm with 280-290 tq. This was on a mail order tune on a Mustang dyno. Gonna be sending the logs to NP and see if they can find any tweaks that might need to be made to the tune.
I don't fell bad though. A 6.0 cam/exhaust/M6 camaro put down 320
Sounds like a very tight dyno haha
mods? motor?
5.3 block bored and fitted with ls1 rotating assembly. TSP228r cam, PRC .650's, full exhaust, K&N drop in, 241 heads milled for 11:1cr, efans, Flt lvl 5, 2800 converter, 4.10's, and mail order tune.Quote:

I thought the same thing but everyone was dynoing much lower than they expected. A pretty sick Cobra put down 601 on a dynojet a few months ago then only put down 488 I this mustang dyno.Quote:

That's less than what a stock 5.3 puts down! There's definitely something going on with that dyno!
Stock 5.3s put down way under 300 to the tire.Quote:

Well, regardless of what it put down, I can hang nose to nose with with a 5th gen SS from 25-90. In a 4400lb truck I don't consider that bad at all.
I'll just use this number as a reference point for more mods.
The dyno sheet could come in handy suckering someone into a race!
Don't put too much thought into dyno numbers. They're only useful for tuning and doing testing after various mods. They're all calibrated differently. Know how DynoJet got there initial calibration? They ran a Yamaha VMax bike on it, took Yamaha's power numbers and told the dyno what the bike ran. Ever single number ever put up by a DynoJet since is based on that number.
Interesting, so that explains all these 800 hp supras getting beat by 400 hp cars lol, so is there any way to really know hp numbers? Maybe there should be a standard that every1 uses.
There is a standard.... 1/4 mile times
Yeah dynos are so varied it hurts but that sound low.
Like pl4boy said dyno doesnt matter 1/4 mile is the standard.
And with my current best 1/4 time I'm keeping up or quicker than most current sports cars.
what are your times?Quote:
