NNBS with Racestars/M&H 390's
#11
Not sure how well they work compared to the 15", but they did a 1.69 60ft off idle, I tried building boost at the line and built way too much, and they spun pretty good. I havent put the caltracs bars in the top hole yet, but would like to try that. they hook really good on the street though too. That was on my turbo 03 though. On the 07, with the 275/55/20s it would roast the them through first and part of 2nd, and spin pretty good on the 1-2 shift, with the M&Hs on, it hooks on the street, and the track, and doesnt spin at all on the 1-2 shift. I like them so far.
