pre dyno pull question - ZR-1 Net Registry Forums

ghlkal · 07-18-2013

Now that I have #2180 running well (at least I think I do), I want to do a base line dyno pull before I do any mods.

The local place has a Mustang dyno, and like pushrod was, I’m hoping for about 320rwhp (375crank * .85). If I got numbers like pushrod did, I’d be very happy (see http://www.zr1.net/forum/showthread.php?t=20712)

The shop said I should have AF measured during the run. I don’t think that’s necessary since this isn’t a dyno tune. They’d have to weld a bung in (and charge for that), but once I replace the manifolds with headers, that would be useless.

So here’s my question – is there any reason to have AF measured during the dyno pull? (What haven’t I considered?)

Thanks
