Hi fellaz,
I just got a mail-in flash along with a 3" full turboback with test pipe, MBC set at ~20 PSI. I just went to Bristol Motor Dragway last night and ran terrible. My best run with a 4500 rpm clutch slip and shifting at redline was a 14.516 with a 2.253 60'.
Possible reasons

1. This was my first night out at the track. However, I still expected at least 13's.

2. Bristol is pretty high in elevation (1475') and is slightly uphill.

3. My flash is designed for once I get the walboro fuel pump and a k&n filter which I have not yet installed.


I have seen people with my mods well into the 12's. Any ideas on why this is happening?

Trap speed?

Best trap speed was 97.49 mph on a 14.928 run. On my best E.T. I ran 95.58 mph.

Ouch, that's pretty bad and probably only good for low 14s. Were there any other Evos there? If so, did you compare times? The elevation is obviously a big factor but so's the weather, was it hot & humid too? Even so, I would imagine you should be trapping around 106 at sea level and running high 12s so your times really are way off even factoring in elevation & temp.

One problem is that the you have not replaced the fuel pump, the settings that were programmed are with the upgraded fuel pump. So you probably are still running rich.
Altitude also plays a factor. Well replace the pump and let us know how it turns out. It should only take about 1 and 1/2. maybe more it right under the back seat.

Took the car to the track here in Houston, well Houston Raceway Park in Baytown.
60' time was 1.841 with a 1/4 mile time of 13.374 @ 101.43mph.

Only Have a full 3" Exhaust, S-Afc I, Boost controller @ 20psi, and Hks racing intake. It was very hot and hummid. But then againg that's Houston.
