Performance estimates?
I just fixed my secondary turbo issue and getting a 11-8-10 pattern now, only mods are chopped airbox with new stock filter and a 3" downpipe
it feels pretty good now with the boost on par, what should it run in the 1/4?
what top speed should it hit?
can it walk ls1 fbodies?

1/4, about 13.5 if you drive pretty good.
Top speed, however fast you can go. I have seen people peg the speedo.
Can it walk ls1 f-bodies. NO. Unless they suck at driving.

You're hitting 11psi with only a chipped airbox and DP?
This eludes me to my small preminition that perhaps even the 3 mod rule shouldn't be encouraged. I have a feeling (from what I read of other's experiences), that going the DP/CB/Intake route (those being the ONLY 3 mods) will result in "some" boost spike. While 11-8-11 may be bearable, it certainly isn't "right". Lean or rich are both problems if left alone for a while.
I think I am going to invest in a PFC before most other mods than the DP/CB I am about to have in order...hmmm

I've hit 160-165 in stock trim.
It's certainly not aerodynamically pleasant, but certainly possible to get close.

I thought a strong all stock FD can hit 13.5 in the quarter with a good driver
with the cheap airbox mod and a DP the same good driver can do better...
It depends on how well you drive the beast.
Wanna go try out in Milan Dragway this Thursday (6/9)? Gates open at 5pm for a private event that I was invited to and I can bring some others with me. $40 entrance fee for 3 hours of racing with a limited number of cars so you get more passes. Check www.mirotaryclub.com for more details

For comparison:
Vehicle Year and Model Cd Area (m2 ) Area (ft2 ) Cd x m2 Cd x ft2
1994 Mclaren F1 0.310 1.784 19.20 0.55 5.95
1993 Mazda RX-7 0.290 1.796 19.34 0.52 5.61
From the factory, the car is aerodynamically limited due to the lack of horsepower to the max speed (with no wind conditions helping/hurting, nor incline) of 164.85 MPH @ 6595 RPMs.
With 325 BHP and 285 TQ, the car will achieve 175.61 MPH @ 7011 RPM's.
With 385 BHP and 330 TQ, the car will achieve 182.58 MPH @ 7279 RPM's.
With 425 BHP and 380 TQ, the car will achieve 185.53 MPH @ 7392 RPM's.
With 475 BHP and 415 TQ, the car will achieve 189.68 MPH @ 7552 RPM's.
With 500 BHP and 435 TQ, the car will achieve 191.49 MPH @ 7621 RPM's.
Now, take out the 4.11 rear end and insert the automatics 3.90:
With 325 BHP and 285 TQ, the car will achieve 177.96 MPH @ 6755 RPM's.
With 385 BHP and 330 TQ, the car will achieve 186.07 MPH @ 7052 RPM's.
With 425 BHP and 380 TQ, the car will achieve 189.74 MPH @ 7185 RPM's.
With 475 BHP and 415 TQ, the car will achieve 194.38 MPH @ 7355 RPM's.
With 500 BHP and 435 TQ, the car will achieve 196.47 MPH @ 7431 RPM's.
With the 4.11 rear end and a 5mph tail wind:
With 255 BHP and 217 RQ, the car will achieve 167.97 MPH @ 6299 RPM's
With 325 BHP and 285 TQ, the car will achieve 181.39 MPH @ 6739 RPM's.
With 385 BHP and 330 TQ, the car will achieve 189.48 MPH @ 7059 RPM's.
With 425 BHP and 380 TQ, the car will achieve 193.15 MPH @ 7191 RPM's.
With 475 BHP and 415 TQ, the car will achieve 197.81 MPH @ 7358 RPM's.
With 500 BHP and 435 TQ, the car will achieve 199.78 MPH @ 7428 RPM's.

brought back from the dead:
i did 13.4 at 102 with a 1.99 60 ft on stock sized street tires, my first pass at the track, with a downpipe and intake.
i now have a high flow cat and a catback is on the way, do you think i can get into the 12's with that?
