I do have a 2.5" DP and a 2.5" muffler delete pipe. Besides an exhaust upgrade to a full 3" or cams, can anything be done in the flash to give me more top end?

 

You could get a AFC and pull some more fuel out on the topend with race fuel , and i had it backwards 2.5 dp and stock mid section . Just for a refrance the best i could do with afc , mbc and cone airfliter was 12.9@105 BUT with some race fuel , truning up the boost and take out some fuel on the top end I got to 12.5@109 hope that helps out ?

 

Al, any thoughts on the above question?

 

I think its your driving. You picked up 3 mph with the same ET. ET is all driving. MPH is a better measure of horsepower. At 106 mph you should be running high 12s. You also ran a better 60 ft this time with more MPH as opposed to a slower 60ft and less MPH last time. Slower 60 fts would normally mean more MPH if your spinning at all, but this time it was a quicker 60 and more MPH, so your definetly making more HP then before. Get the 60 ft down to low 1.7s and shift faster and you should be there!

 

OMG, don't go to Mason Dixon. Go to 75&80! It's been 7 years since I dragged raced and I live in California now but my 3000GT VR4 ran a best time of 13.32 at Mason Dixon but 12.88 at 75&80. Most people I talk to say there is a small uphill at Mason Dixon before the 1/8.
