Dyno & Bench Racing Forum - How much will it lower ET's

The car is a 99 Z28 with lid, P&P TB, LS6 intake, Pacesetter LT's, ORY, LM1, and a tune. Also added 3.73 gears and LCA's, relo brackets, SFC's, and PHB. So a bolt on car with some suspension stuff added. Have run a best of 12.91 @ 110 mph and on well worn street tires. Managed to get one 1.99 60' but usually in the 2.0's.

So how much quicker should I run with an SS4000 and a set of M/T ET Streets on a set of stock 16 in. rims? Looking for gains others have got from adding that combo.

hey man i think i met you at the track rental....i ran on my streets 12.6@112, put james dr on my car first time out not power shifting 2nd gear 12 flat then as the track got stickier i finally got that 11.80@118 so I SAY YOULL LEAST DROP .80 of a sec with better dr honestly i can run high 12's all day with my junk sumis
