Timing questions

This morning I went down to the local mustang dyno for the first time. I was kinda supprised when he showed me the results. 318/968 @ 1200* 35psi Will advancing my timing 1-2* and adding more fuel help level out my #s, or should I be happy where I am?


Thanks,James

Holy Crap! That is a lot of torque! Awesome numbers, Jim!

What RPM did it start to fall off? The stock lift pump seems to starve the injection pump for fuel at higher RPM, if the numbers peaked at 2000 RPM then fell right off you would make more power with high flow banjo bolts and the piston lift pump.

Wanna,

I wish I knew, the print out I got does not have rpm. It only has speed in mph isn't that weird?

Nope. They must not have an optical tach for the diesels. Kinda lame though.

You can work out the RPM for MPH given what gear you used for the run, your rearend gear, and your tire size.

Thanks, I'll have to do a little math this evening. The curve never really falls off since I told him to stop at 3000rpm, I didn't see any reason to go higher my trans shifts at 2500rpm.

318/968???

That is a very low HP/Torque ratio, isn't it?
It's insane...
