Default Long Tube ET Gains?

After the Hooker LTs install I went from 13.8@102 to consistent 13.4s at 104.

I just got MID-Lengths installed by ICON and all I can say is WOW. The car feels completely different. The headers really wake these engines up. I haven't been to the track yet but I would say probably .5-.7 improvement.

A solid .4 and a 2 MPH increase. That was with a full tank of gas etc. compared to what I ran at the track previously.

Alright guys so about 4. to .6 tenths seem to be the consensus, I'm going for 12.5s with bolt ons. Before headers the car ran 8.5 in the 1/8 on a 2.0, wish I would have gotten some drag radials on it to see how well i could get it to hook with the QA1s and new back suspension.

I had the same set up as you minus the gears, with the long tubes it really wakes the car up, when I would flash the stall before car felt choked in the power band. Now it just pulls really hard mid way to up top, dpwn low if you flash it on street tires, before it would spin, not it just skates all over the place, deff picks up a ton of power out these old Lt1 mills, car feels really responsive too. Works great with the vigi stall I have
