Take a guess at what my HP and Torque should be with my new combo. Also what should I be at in the 1/4 mile? My car still has the stock 2.73's in it

TFS Twisted Wedge Heads, TFS Stage 1 Cam, Edelbrock Performer 5.0, FMS 65mm TB, BBK Long Tubes, O/R H-Pipe, Flowmaster 40 Series 2 Chamber, Pro 5.0 Shifter, 17x9 2003 Cobra R 245/45/17 Nitto 555's up front, 275/40/17 Nitto 555R's out back

I'll keep an eye on this one, as my h/c/i is the same, and my exhaust is similair.

295rwhp. Im about to to buy the exact same combo as u except with the trick flow intake.

Hope to see good numbers either way.

i say 285 rwhp. Do you have pulleys? For tracks times im gonna guess 13.7's.. The 2.73's will kill you on the track.

290RWHP and 320RWTQ

280-290rwhp seems like the most common response and no I don't have any pullies on my car. I would have thought that I'd be somewhere around 13.4 or 13.5 with the 2.73's then a high 12 with 3.73's after I get a new balancer and a few other little things fixed, I'm getting a rearend rebuild kit and some 3.73's to put in.

trickflow stage 1 cam
scorpion 1.6rr

I would deff get some pullies as well, they are cheap and proven HP adder on our cars.

Only reason i said 13.7's was cause when i had 2.73 gears (all the bolt ons and cobra mani) on a 100 shot all i could manage was 13.8's on street tires. The 2.73 gears just plain blow. Once i went to 3.55's i was running 13.9's without the juice but i was on nitto's which was also a big help.

Theres alot of other factors when comparing two totally diff setups.. i guess the only way to find out is to run the car.

let me know about pulleys... I have a set I just got, but decided not to use them as I already have them apparently

-ASP Aluminum pulleys... brand new, never used, black to match the others...
