Anybody have F Body APS Results? Dyno and or 1/4 times I know the F Body APS kit has been out for almost 9 months now and i purchased in the first batch and i'm still installing mine. Has any one finished and have dyno numbers and 1/4 mile times? If you guys can post your setups whether its completely stock or if you have a built motor or a stock bottom end with heads and cam that would be cool. Just curious to see where i'm going to be at with a stock bottom end with heads and cam running 7lbs of boost.

Kwikkar is your car an auto or stick? 720 seems a bit low to me if Jms hit 700 at 10psi. What heads on the car and cam and intake? Maybe from turbo problem its lower than it should be or maybe it just needs more tuning more timing,leaner afr ..what octane? Any
alc/meth injection?
I was really hoping to see 800 for sure at 15psi or a bit higher and hoping can get 850rwhp out of these standard snails on the 408. On alc/meth though.
APS also if you search has some dynos on previous threads ,their dyno is cam dynamics and it reads lower than dynojet. They were running only a 346 though forged up with afr heads, fast90/90 combo and gt11 lingenfelter cam. As you can see I am going to be running similar with afr 225s, fast 90/90 and milder gt-7 cam for starters but in 408. Oh one aps was on standard wheels in the turbos. One was on different wheels they were testing out. And not talking the dyno on the old tired bone stock ls1 on their website.
Anyway looks like JM should be well into the 9s soon and anything 10s is more than fast enough for me.Street cars dont' need to do 9s.At least not mine..

I think that with this kit you would most likely make more power with a built 346 or 370 than with a 403 because of back pressure, having said that, the kit should make 800+ anyway but I do not think that it will make any more on a 403 than on a 346.

Well I guess we will see what happens. I am not totally fixated on that number. If can run 10.99 will be happy camper. I wanted the 408 for off boost torque and bigger engine will spin the turbos up a bit faster as well.Went 9.5 compression,will run alc/meth injection.I guess find out shortly what jm dynos at higher boost levels but he is also an auto and I am an m6 and hoping to stay m6. M6 of course should have more rwhp than an auto if they are similar combos. Jm build and mine are not that comparable. I think mine is more comparable to the aps build with the standard turbo wheels.

Oh don't expect more hp necessarily. More torque off boost and expect to make same power as 346 or 370 at lower boost. Lower boost has some advantages .I realize max airflow of the standard turbos should be around 1000 engine hp from their figures of 50 pounds per minute on their website. Can always pick up some more with small shots of spray. Have a wet kit just sitting around the house if need be.

my ride has zo6 cam , 317 heads ls6 intake good fuel setup and on a dynapak dyno at 12psi it made 694rwhp at 6000 rpm and was still going they stop it short because its on a stock bottom end that has just ARP rod bolts they didnt want to kill it. instead of turning the boost down (too much fun) need something better (370ci) i want 850rwhp or more but need a few things frist so do it up guys turn the boost up and let us all know how it works out good luck to all i love this ****
