First off I want to send I HUGE thank you to Tim and Keith at Razors Edge for staying late to get me on the dyno tonight. I was under the gun to get a tune after installing the KB, as the custom tune on my Predator wasn't cutting it. I really want to run the truck this weekend at a club track event and almost gave up hope. Keith burned me up a program with the Revolution software and I am very impressed with the results.

Max Power 450.9 @ 4750 RPM
Max Torque 533.9 @ 4250 RPM

Mods: 4lb lower, 3" on KB, LT's full exhaust, BaBolt TB, 90mm MAF, hot air kit, e-fan & pump.

Before installing the KB I made 402/499. (Going from faded memory, have to pull the sheet)

Pull was made from 65 to 95 MPH which was about 3200-4750 RPM. It was a hot lap also as the first was only run up to 80 mph to make sue all was well with the fuel and timing before running it hard. The HP hadn't quite peaked yet and the torque was over 500 all the way

These are pretty handsom for a Mustang Dyno (add about 13% for Dynojet readings 509.5 HP/ 603.3 ) and there is definately some power to be had in the tune. Keith didn't even make any tweaks to the program yet.

We will see how she runs at the strip Saturday and I will post the sheet when the gallery is open again.

Once again Keith and Tim can't thank you enough. Let's tear it up(hopefully not the stock block) at the strip Saturday.

Ps. I'm not sure if this "officially" puts me in the 500/600 club?

 

 

 

CONGRATS ERIC

Can't wait to hear your ET's

 

Excellent

 

You in "the club" d00d ...

 

HEY!!!! What event is this.....................tell me tell me!!!

BTW, sweet numbers
We'll pray for your block!

Now go out there and get a number. Let us know how you do at the track. -Mat-

 

stock block go boom.

 

how many lbs you running with the 3" upper and 4lb lower? NIce number hope she runs good.

 

Just because you put a KB on a stock block DOES NOT automatically mean the damn thing is going to blow up!! The KB is exponentially more efficient than the Eaton. As long as you keep the boost levels(cylinder pressures) in check(under 15psi), and have a safe tune(verified on a dyno with A/F readings), and are mindful of the power under foot, then you should be fine!

I'm pushing 500rwhp (2lb lower/ 3" upper) with mine, and have had it on for several thousand miles, and upwards of 30 1/4 mile passes thus far, with nary a whimper out of the stock longblock. I have run back to back to back 11.60's at over 116mph, after driving 150 miles to the track one way!

I have since backed the boost down a bit (2lb lower/3.25" upper) in the cooler weather (to 12.5-13psi), and the truck still pulls much harder than it ever did with the Eaton, and with a SAFER A/F ratio!

Had to edit because I noticed I'd hit a wrong key....damnit!

 

owheelies,
I just noticed your pulley combo. My truck with a 2lb lower and 3"upper (as I mentioned above), produced 15psi. With a 4lb lower and 3" upper you're probably pushing 17+psi at peak, which is definitely pushing the envelope in terms of cylinder pressure. Just be careful! Goodluck! Nice numbers by the way!

Later,
Rob

 

Nice #s!! Be careful on the strip.

 

on the numbers. Are the before numbers on REM's mustang dyno too?
