Had the car tuned this week at Performance Specialties Inc. in Glen Burnie, Maryland. Final numbers were 348/355 on their mustang dyno. It was a little more than I was expecting, my mods are in my sig. Basically LT's, ORY, cat back along with Lid, LS6 intake/P&P TB and some minor extra's. The car has 62k miles.





Is it true that Mustang dyno's are about 5-7% lower than dynojet's? I'm no bench racer, but that would mean around 366-370 on a dynojet, that seems a little fishy for a bolt on car. Maybe the mustang dyno was feeling generous that day

The car trapped 107 before the LT's, ORY and tune. I'll find out shortly what it traps now

Nice numbers!

I hope i can put down similar numbers

I think your right on track. most bolt on cars I see are in the 360rwhp range so your probably close with the 5-7% conversion.

Yeah those numbers are just about dead on. I bet she's a blast to drive now.

I can't tell on the graph, but I do see that you made both 3rd and 4th gear pulls. Did you get the numbers you posted in 3rd or 4th gear? Just curious.

most likely 4th.

That's what I figured, I'm just curious though. I've never seen anyone dyno a T56 car in 3rd.

From my understanding, you're supposed to do all pulls in the gear where you have a 1:1 ratio, 3rd in the 4L60/E, and 4th in a M6. My tuner told me he was adjusting the tune and kept doing pulls, but did the pulls in 3rd gear so that the car went through the rev range quicker in comparison to 4th gear, causing less strain on the car. Once all of the adjustments were made and the tune was completed, a final run in 4th gear was made for the final numbers you see, under "run #1".

I think I that's what he meant anyways.

Anyways there are still bolt ons/better combinations that the car doesn't have, ASP pulley, fast 90/90, electric waterpump etc. Are some of you bolt on M6 guys seeing 370's rwhp on dyno jet's?

I figured that was only possible with a small cam.

dude congrats...

same set up on an 01 m6 z28 all bolt ons no tune. I did around the same. Yes I did see around 370 on a dyno jet. I will find my dyno sheets and post them again!

I trapped 114 with all bolt ons!

I had near the same mods + ASP but - PP throtle body on a dynojet and had 345 & 360tq. Nice #'s

wow, can you say factory freak!?!

Yeah I knew it was supposed to be in the gear closest to 1:1, I was just wondering why any pulls were done in 3rd. Thanks for the clarification.

My 00 M6 did 360/370 w/ mods in my sig SAE uncorrected on a dynojet. Very strong numbers there man.

347fairless

I trapped 115.45 Bolt ons full weight.

So you only gained 2 mph w/the cam??

Nice numbers. I had Jeff tune my car as well. I put down 334/348 with LTs, catted Y-pipe, Lid, catback.

They were probably the highest bolton numbers I think Ive had on our dyno to date honestly, and with a part or two not yet to be full boltons to boot.

For comparison to ravensfan car for example, grannys car with the same mods but stock catback made 349/370 on a dynojet. BW Id guess yours would make a little over 36change/375 or so on a dynojet, but we dont dyno race too much round here That hp is capable of trapping 112 on accident, 113-4 on a decent pass or better at full weight, little bit better than what grannys car did Good driving, good air thats capable of 115-116 and change mph at your weight

BTW we did the first couple pulls to get the car in the ballpark in 3rd, not sure if you guys are aware of the load a Mustang can put on a car, but we have had people overheat cars on a pull or two because they are leaning on them too hard. We here "well weve made a bunch of pulls on a dynojet and it never gets EGTs like THAT".... well thats because theres no load Low geared cars can take something like 7-10 seconds sometimes to make a full pull in 4th on our dyno. His car was wayyy lean to start with so we got that in the ballpark, then kept it in third so the gains could be seen from first pull to the final tune (thats the bottom two curves) Then we did a final pull or two to make sure the hella load doenst make it knock any in high gear where the timing was. if its cal'd right and used right these dynoes make for awesome tuning tools (weve pulled 3600-3700 lb cars off the dyno and ran new bests on the first full pass a bunch of times, anything from 11 second cars to 8.90 cars) Used wrong and they are worth less than even a dynojet

I too feel the MD is a better tuning tool due to beeing able to load the car. I actually like it when people think my numbers are low since it was on a MD then the car traps well to prove it. I feel these MDs get more torque and midrange out of cars too. Everyone says the T-Rex has no bottom or mid range. Well mine feels better than the stock cam did and I have the dyno curves to prove it. What was worse is not only do the numbers seem low due to it beeing on an MD, but I also ran a 9" with 4.56 gears and real heavy wheels with 26" tires (Idealy should have been a 28" tire).

Nice numbers. Get it to the track now.

Im hopefully heading up your way soon jeff, put on the ls6 intake over the weekend and im putting in new valvesprings and clutch soon, so im hoping to pull out at least these numbers if not higher

Really, bolt-on cars around here are like 335-350.
I guess we have tuff dynos lol.
