Do you have a buschur downpipe or invidia downpipe?

buschur downpipe .

 

this would only happen if he drove around WOT all day long on pump gas. i run the '03 @ 25psi & spike it to 27 @ the track. the motor is fine & will hold up to 550 crank hp b4 blowing up. remember the basic 4G63 design has been around since the mid 80's...

 

oh my goodness, this is some sick stuff. can't wait to get my 9 and do "minor" mods to it for huge gains

 

I went to the track yesterday

Did 3 runs with my evo 9 I run 12.6 at 111.44 mph my 60’ 1.921 , (very cold) my tires
did not hook .I have to go when its little wormer like 60, it looks like I can do low 12 s or even high 11s

 

good luck man on your goal of 11's. what does your a/f ratio look like? it looks like you could gain some torque if you take out a little fuel on the topend...

 

a/f ratio 11.9
