You should be making more power than that. But without specifics (ie. what trim vortech you have? I thought i remember it being a T-trim), what your a/f is (show dyno graph) and total timing.
You should make closer to 600rwhp, if not 600rwhp on a good race tune with added timing. The aftercooler is going to be your limit though. I'd suggest looking into water injection. It's safe and will bring your ambient temps along with your aftercooler down into or below 0* |
My engine comp was 9-1 when it first was done, after my huge ordeal this summer I was/am unable to cuntact the ahole who put my cams and springs in.
I bought a compresssion kit and it should be here friday.
Yes I should be making 550+ hp I totally agree!!!!!!!
And yes the Shop I am at now (MMP) totally suggested the methanol injection as my next step...
Right now my steering rack is shot, my front springs are too short...(rubbing my cats everywhere!) so sat I am putting on a new rack and ford racing front springs to lift me .75-1" up in the front.
I have another tuner/dyno lined up to do another dyno run at a different shop.
BTW---I lucked out that my motor was built well and wasn't crapped together......no leaks anymore......But I got shitted on the specs...
I have the first gen Sc from vortech...bought it in 2000.....But we put a 2.65" pulley on it........was 3.?? somthin.
I am getting about 15lbs of boost at peak........
10 degrees of timing street tune 475 hp
12 degrees of timing race tune 530hp
My air temp stays about 116-120 degrees (a bit high)
I am definatly going to re tune it cause the Dyno I am going to is "state of the art" and they actually have compression tools...DoH!
I wasn't aware that Lonestar perf. was underdeveloped in the dyno area.....it was pretty getto......he had to fuk with his Y-band for 30 min to get it to even work.......
Yeah...Yeah.....I didn't get the best service, but live and learn.....
I am still happy though.....3rd and 4th scratchin is fun and she runs strong......I can launch crazily from first and raise the wheels a bit if I stick (17X8 nto1's) and it's weird having so much power in 5th gear with this TKO 500
tranny. It used to be so sluggish.
Thanks for all the feedback.....
We'll see what this next tune does....
I got Dyno'd ...... :)
