Race Proven Motorsports 9.46@143 STOCK LS7!!!
We installed a 4l80E in a customers car from Quebec. The car ran a best of 9.9 at 143 before when it was a 6 speed once. It was consistant 10.0 car. It had a Vararam, Twin Disc clutch and a 185 shot.
We installed an RPM 4L80E Swap, Qa1 Shocks and a CCW Drag Pac and he added Headers and bumped it to a 200 shot. I couldnt beleive when i heard what he ran. 9.46@143.8 mph 6.05 @ 114.1 1.32 60' This was also the first time out. Alittle more tuning and i think it can go 9.2-9.3 We are talking about adding a cam and trying to get into the 8's on a STOCK besides cam LS7 |
That unreal, :cheers:

The C6Z is a great building block for a low 9/high 8 second car , but when you add up the price of the car plus some form of forced induction an auto trans conversion it's still big bucks , but at least the prices on used ones continue to drop , and a nitrous kit is definitely the cheapest way to run a big number . |

:lol: A 427 LS7 with headers and a 200 shot and an auto , in a light C6Z running 9.40's is pretty much running at it's max potential and impressive , but an LS7 427 is no joke even with " stock " heads and cam . :lol:

Final number last week, with the same rich tune, low timing:
1.32 60' 5.97 @ 116 mp/h 1/8 9.34@ 143.8 mp/h Rich afr and low timing hurt the 1/4 mp/h. Better time to come stay tune. Later, Sébastien |
