So a friend (Tomz28) of mine that I had previously tuned, decided to install an APS kit. We tuned it on the street to get the fuel right, since he had installed green tops. On the street it felt ferrousious! He took it home and told me stories of whipping cars left and right. Well today we had a chance to put it on the dyno and see where the power is and possibly extract some good numbers from his stock bottem end. I was figuring close to 600rwhp. First and only pass churned out 694rwhp and 617rwtq!!! So I check why it is soo high, the boost hit 12.46psi! Yeah, I decided not to continue until he either controls the boost or gets a forged low compression short block. It wanted to go higher, and if built we may see high 700s. Here are the numbers from the APS standard kit, as well as the boost we logged through the dyno.

This is on the Ford Green top injectors?

12secSS

iTrader: (30)

Yes, the are the Ford SVO green tops (42#). He has his fuel pressure at 62psi, so these are 51# on that pressure ... no wonder they were at 95% duty cycle while running 11.7 AFR.

wow awesome numbers. Is this the combo with the stock 317s & a Z06 cam? I feel bad for that stock shortblock

Great numbers Congrats and nice work.

APS kit is awesome.
So stock Bottomend? H/C/I??

12secSS

iTrader: (30)

Correct , just stock 317 with the ZO6 cam. This is beyond what I would safely feel like pushing a stock bottom end.

Longer downpipes , did it not fit your exhuast ? What exhaust is on the car ?

Whats the setup .. engine /drivetrain / fuel system ?

tomz28

iTrader: (20)

i didnt want exhaust i like the way it sounds right now it not that loud at all
we just add about 20 inchs to the down pipes it made a hell of a change in the sound

the funny part is that AFR was rich as hell and that was only 12 degrees of timing on 91 pump gas how much power is still in there ******* scary !!!!!!

So, reading the graphs, are you sure thats RWHP? It says that its fly wheel HP??

did you run the car at the track yet? AWESOME numbers i'm installing my kit now and i've got heads and cam on the car now can't wait to see what mine will put down

gallardo259

not to hijack the tread, but i was wondering if the aps kit fits on lt1's...with a little modifying or not?

Cchris1109

iTrader: (11)

i dont wanna sound like a jealous person or what not, but I do believe that this is fly wheel hp and not rear wheel power. rwhp would be 569 with a 18 percent drivetrain loss and i believe that is more realistic on that car with 12.5 psi

edit: on a side note that is good numbers even if its 570 whp @ 12.5 psi

tomz28

iTrader: (20)

thats just the way the dyno display it and if i took you for a ride you would it was right

I made 569rwhp 6spd 3:73's 10bolt on 9psi with my Vortech S/C setup when I went to my first dyno day at MTI, so I am tossed up on his power although it does seem a little high, but those Zo6 cams do work well on turbo setups. Congrats! What dyno is that just curious. On another note you have to subtract the boost from the base FP if it isn't boost referenced IE: 62lbs -12.5= 59.5 for the injector flow rates to be pretty accurate etc...
