Dyno numbers are in!!

Fast stang16 · Feb 19, 2015

I was finally able to get down to the dyno tuner. My lean problem was due to timing being set to 41 degrees. I adjusted it down to 10 degrees and changed a few things on the chip and it's putting down 280 hp at the read wheel 315 ft/lbs. Based on my set up, are these good numbers?

1994 5.0 forged internals, 12:1 Pistons, x303 cam, edelbrock upper and lower intake, trickflow heads, 70mm throttle body, 1.6 rockers, msd ignition, 24lb injectors, underdrive pulleys, bassani exhaust, 4.10 gears, 5 speed

Are you really running 12.0:1 compression?

That's what the guy I bought it from told me?? Kinda hard to tell with out tearing it all down

That is like some super high compression. That's getting up into the land of FI and race-built engines... I hope to god you are running at least 93 octane and pulling some timing. I don't know how your engine didn't blow up at 41 degrees of timing.

12.1? Gonna need some race gas all the time in it. Definitely doesn't sound right to me.

I only run premium! I cant say whether it does or not since I did not build it. That was info passed along from the prev. owner. As far as numbers, how do they sound?

Should be making over 300whp with that compression. The cam is probably holding you back a bit... and I doubt it's 12:1. You'd need to be running dome pistons.

I'm going to try to get my hands on a bore scope to see what I'm working with, any other suggestions?

My guess is it's closer to a 10:1 compression ratio, at 12:1 you would have a problem if you're not making over 300 horse. And at 40* of timing I don't know how you didn't detonate!

I'll say I've seen a stock short block 5.0 with a lesser top end set up than yours end up with 335 hp.

RichV · Feb 20, 2015

41??? I don't think it would even run. You did have the spout out right?

Whatever the PO told you is most likely BS. But an aluminum headed, cammed, (and intake) 5.0 should be over 300 all day long.

Your #s aren't bad, just not the norm. Maybe the guts aren't what you were told. Go get that scope!

Fast stang16 · Feb 21, 2015

Yes the spout was out! If y'all have seen my previous post I had been having a problem of it "bucking" at a steady rpm, as soon as we timed it right all that went away! I was thinking it was kind of low my self, me and the tuner were talking it doesn't really sound as if it has a xcam, you can hardly hear any lope? He said he thought It was probably a b-cam

The 4.10 gears can make your dyno numbers lower. Also what kind of dyno was your car on? Pull a plug and shine a light down in the chamber and see what the pistons look like if you can. I'm thinking its a stock short block hci car. Not to upset you but the info from the previous owner is vague regarding the bottom end.
