Here you go guys here is the set up i will have dyno charts and videos to come in a few days

APS kit
Stock Bottom end
Heads and cam- SLP LS6 stage III heads with 236/236 .590/.590 112lsa
underdrive pully
corsa exhaust
twin 255 walbro pumps
60lb injectors
stock rails and lines

On a MUSTANG DYNO it put down 587.6 rwhp and 522.8 rwtq
that was with only 7LBS OF BOOST with a II bar speed density tune. The boost never creeps up at all not even on the street which i thought was good. The car feels great however i wish it put more torque down but i think its the cam that is restricting the torque.
Anyways i believe on a dynojet the HP would be in the 600's.
not sure if i will turn it up to 10lbs of boost because i still have the stock rear end and only a spec stage III clutch, not sure how long any of that will last with 10 lbs.
What do you guys think?

Great power for 7 psi. A cam change would definitely benefit you. I would say you are walking a thin line on stock internals. Good luck!

Those are great numbers.

I would say leave that cam in there untill you have a chance to put in a new shortblock. No need to squeeze every bit of power out of the car if you are on running close to the limits of it.

yea i hear ya i was actually figuring that i'm better off with the TQ being way lower than the HP so that things will last a little bit longer. the good thing is the car is a toy not a daily driver

Timing makes a huge difference in torque . Are you running alc /meth injection.If so then you can dial up more timing. More boost would of course give more hp and torque but I would not push a stock short block past 7psi or so. Better safe than sorry unless you can buy new engine right quick.Greedy and stock bottom not a good thing. What do you have for rear end gears.?.And wonder how much more power that spec 3 will hold?Nice to see another aps car completed.
I am so tired of looking at everyones cars done already .I am waiting on my 408 maybe should have run the stock motor for a bit.

I hear ya loud and clear, thats what I decided to do. Just fired it up a couple days ago. Should have the rest of my parts next week than off to the dyno!

To the OP, I think you are running to much boost for the bottom but good luck though and enjoy it!

Thanks guys!! I'm no way near ready to build a motor i have a baby on the way which is way more important. Besides the wife will kick my *** if i drop another dime in the car lol . I'm on a stock rear end too which sucks, but thats my next step is a rear end before the motor. not running meth

If u have a baby coming do not turn up the wick your at the hp level now where stock parts break

Have a cc ready you will need it

Agreed, but way past where the stock parts berak IMO. Good Luck though, would hate to see it sit after all that time and money!

590rwhp on a Mustang dyno is very close to 650rwhp on a dynojet. And at 7psi? Somethings not adding up. You would need closer to 12psi to hit those numbers unless your tune is very aggressive and even then you would still need 10psi easy.

BTW, do you have any problems with your driverside air intake rubbing your steering linkage?

Great numbers. For sure don't up the boost. You should smoke just about anything out there.

thanks guys. i don't think it would make that much more on a dyno jet my tuner said 7 - 10% more which should be around 615 - 620 . In the beginning i had a problem with the driver side air intake you have to re adjust it so it won't hit. it just makes it

Congrats man those are great numbers with such low boost.

So you made 522rwtq with 7psi on MUSTANG DYNO and your not happy huh???
I would be the very very happy.

SS Stolen what dyno numbers do you have for comparison? and how do you get a 348 iron block. I thought all 6.0 are 370 or is that only if you overbore them a bit?
Part of the reason he might have those numbers is he is still I thnk on stock compression? For sure up in the 10 to 1 range. That has to help but can't see how aggressive his tune can be if he isnt' on alc/meth. He does have heads though and fairly big cam as well. And his car is an m6 not auto.

thats correct the car is a m6 and stock compression. The power makes sense. There is another stock aps car on here i forgot his forum name, however he is completely stock 98 ss on 7 psi he put down 515rwhp and 508rwtq. now you have to figure i have the ls6 intake manifold plus heads and cam and my car before the kit put down 440rwhp 390 rwtq. The heads and cam gave me right around 80-90 more wheel hp when i had bolt ons. Now add that plus maybe 20 more hp on my set up now with the boost you figure the power is right on. Heads and Cam give more power to a forced induction application than a n/a application. it makes sense

I just got off the dyno at 3pm today, the car ran just under 8lbs at 7.9PSI, hit 610RWHP and 595lb of TQ on the dynojet in Albuquerque NM at The Dyno Edge.

91 octane pump gas, stock rear, stock shortblock, stock clutch, stock trans, stock driveshaft, stock tires.

All I put on it was 60# mototrons, bmr k member, racetronix with hotwire, patriot dual gold springs, chromoly pushrods

This car only has 8800 miles on the clock, so it still has the tires is came from the dealer with.

I have 317 heads that were milled .010" to lower compression and they were ported to hell!

I expected no more than 540rwhp but my part choices and tuner really got it all running great.

I have dyno vids and power graphs that I will post soon.
