Made 306.2hp@12psi on a Mustang dyno. In spring of '03 I dynoed at 278. Over last winter I did a basic rebuild due to low compression (no porting or new housings), added a Blitz FMIC, hard intake pipes (probably negligable gains), and changed from a Greddy SP catback to a Racing Beat dual tip, a potentially lower flowing exhaust. And I picked up 28hp. I'm happy with it.

I was having problems with traction at the transition on the dyno, so we had to put sandbags in back. haha

Pretty sweet man, good job! Can't wait to get mine on the dyno...once the rebuilt street port is in of course :o

 

302rwhp is great for mustang dyno !

You hold nice tq up high. Comparing to my graph:

You seem to hold tq much longer up in the revs (although mine was done with stock IC and something like stock CB on old plugs).

We will have very similiar mods (except for PFS SMIC vs Blitz FMIC and your flywheel) and I'm interested to see the results once I install straight through exhaust

You're still on stock plug wires ? Do you get any ignition breakup up top ?

Your AFRs look nice though.

 

Wow Ryan, you we're kidding when you said your torque "curve" was flat across the RPMs. Nice.

 

I'll never get used to the mustang dyno's graph. It looks like a hand drawn line with a markee felt tip pen. That and there's not much change in hp to the wheels when the transition happens. You drop from 13 to 12 psi but lose little to nothing to the wheels...torque wise. Not to start a dyno debate, just give me a dynojet anyday, mainly since I've used it since 98 and feel comfortable with it's data and data presentation.

That's because there was no transition I had my switch in NS.

I initially wanted to get sequential numbers and non-seq numbers, but for some reason, I was overboosting like crazy when the secondary came on. I can go out and beat on my car all day on the street with no overboost, but when I was on the dyno I couldn't get it to stay under 14 psi.

Also, even in NS, my boost it a little bit erratic because of my boost controller. Once again, on the street, it is fairly solid, but on the dyno it varied quite a bit.

 

My plug wires are getting a little old. They were changed right before I bought the car, about 3.5 years ago. They were fresh plugs though. I didn't notice any ignition break up.
