Well, my goal with the car has always been to hit 600rwhp. I am currently at 516/463 but thats without spraying the meth yet. My tuner doesnt think I'll pick up too much power by adding meth though because my IAT's are not high at all and I'm already intercooled. So even If i'm in the 540rwhp range after meth...I just want to see what you guys think I can do to hit 600rwhp. Real quick rundown is listed below:

97 GT block .20 over
Manley 18cc pistons
Manley H beam rods
Cobra crank
All arp stupds
MMR stage 3 pi heads
Custom grind blower cams (533/571, 220/230 duration, 114lsa)
Port matched Edelbrock Vic Jr. manifold
SLP longtubes, SLP off road x, SLP catback
6061 sheetmetal plenum, 75mm throttle body

Power adder setup:
Vortech V2 SI
8 rib conversion
powerpipe
Vortech mondo bypass
2.95 blower pulley with 10% over drive crank pulley
Paxton FMIC
Ais tri nozzle meth setup (which is what I'll be getting tuned for this winter)

Tranny and drivetrain:
Built 4R70w w/ 3500 stall, custom valve body, 3.73s w/ built rear and aluminum driveshaft

Fuel:
sumped tank, twin 300lph pumps, twin 6 feed lines, edelbrock rails, fuelab fpr, 60# injectors
------------------

Just a real quick rundown. My last dyno I was seeing 17.5 psi, the car pulled to 6400rpms but I wasnt making any power past 6000. Timing is at 15-16. Do you guys think that the auto is just eating up power? Do you think I'm past the efficiency of an SI trim blower? Just looking for feedback from guys that have had blower setups in the 600rwhp range through an auto. Thanks a lot

since your running meth you could run a higher CR now if you wanted. You could go 9.5 or 10 to 1 and you would hit 600 then. Or a 75 shot of nitrous?

I know your gonna wait for this but once you upgrade to a ysi and youll be there no problem.

Or even with a t trim you may be there

with your setup i think you've peaked the efficiency of the blower and looks like time for an upgrade

My setup now should yield 9.5:1. I dont know if I want to go much higher than that considering I'm at 18psi already, and my meth is going to be spraying pre-blower so possibly i could pick up 1-2psi from that as well. But no doubt a little higher CR and i'd pick up some more power.

Thats pretty much what I've figured with the blower. I'm thinking thats why I wasnt picking up any power past 6k, it was probably just hot air at that point.

Gt04

what you planning for an upgrade?

97stanger

well, I really dont see the point in going to a T trim as I dont want to max that out. I have it between a V7 JT or YSI, and for a $200 difference to the YSI I would probably go that route. The only thing I would be afraid of is spending almost $3k on a blower like that...and what if I pick up 10hp from the swap? ya know

Da**! Here I am trying to hit 400 and you're trying to get 600... I hate you, lol!

What are u running for fuel?

For some reason I would think more would be left in your blower if you're hitting 516/473
a member on another forum was able to squeeze over 600rwhp from a v1 s trim with hp292 cams members name is Jivepepper also another member with a v2 aftercooled hit 517/456 at 11psi with a 3.33 pulley with mhs1 blower cams on a stock shortblock member Bullitt5566 http://www.moddedmustangs.com/forums...ned-today.html i dont know how but I think you should be able to get more out of that blower looking at some of the numbers some have put down with the v1 and v2 on other forums.
