Pretty good numbers. Mine put down 334 rwhp & 325 rwtq through the cat & full exhaust with the mods below except for the dyno was done on the stock converter. I cant wait to get it back to the dyno after I put the M6 in it and get a few pulls with the offroad pipe on.

Edit: Forgot to mention that was on a DynoJet.

I plan on the following:

P&P Heads (Stock Valves, Maybe 2.0/1.56)
Intake to match
CC 987 Springs
Hardened Push Rods
CC Lifters

Maybe Custom Camshaft....$$$.

Nice numbers, especially for a Mustang dyno.

Looks like you gave up an extra 5-10-rwhp by shutting down early. Looks like the curve was still moving up.

Yes I noticed that. I told the guy to run to 6000, but I forgot to mention my tach was off a little.

I also logged Knock on both runs which gave me retard of 5 degrees . My WOT Timing is set to 42 degrees and dropped to 37 when knock was detected.

I'm confident I could made a sure 10 more rwHP if I fix this knock and run it a little higher.

BTW, I have a 93 so an LT4 KM isn't needed, maybe I'll drop timing a few degrees...

ALso, what wasa your A/F? Playing with that can net some serious power/torque.

Don't know, didn't have the wideband hooked up.

Don't have a bung for it. Maybe next time.

I hear 12.1 ~ 13.1:1 is best for N/A... any thoughts?

With a wideband they just stick it in your tail pipe. 12.8-13.0 is about where you want to be.

The guy I talked to at the Shop said it's best to have it as close as possible to the engine.

Maybe if I get my H-Pipe exhaust setup, I will put one in the middle.

They wanted only $15 to use the clip on Wideband... should've paid for it.

No. But that's from what I've read on this board. 93s seem to have a less sensitve KM to begin with.

For getting your heads p&p and a custom cam talk to nighttrain66. Cool guy and will help you with your setup. At the moment he's working my heads over and I went with the LE3 package which cam is matched to the flow of my cylinder heads. A member of the board made 409rwhp with this package on the stock bottom end.
