Hey guys. I've totally torn down the top half of my motor. It was just running 270's, but now I've installed dual valve springs, 1mm oversize valves, and 280s, along with quite a bit of port work. Anyone have any idea what I can expect to gain? I'm really excited to get the car back out on the track.

 

Except 11.1@132MPH or so with good driving..Good luck is going to be 10's.

 

That would be awesome, but, the track is kinda crappy here. Mainly the air. With a 35R and C16 I trapped 124. It'd be great if I gained 8mph, I'll let you guys know in a few weeks.

 

Boy do I love Bench Racing

 

My car isn't running...it's driving me nuts. I wanna think about what it WILL do while I'm working on it to keep me motivated. And just wondered about how fast I should be thinking it will go. Thanks for the help guy.

 

That beast is gonna hit a 10, drive it like you stole it! How many PSI and what clutch do you have?

 

Running 30 before the headwork, but my new tuner out here is saying 35 is a possibility. Clutch is an Exedy Twin Disc.
