From 100% Stock LS1 to 11sec LS1 T/A Mod List Ok guys, I bought this car when it was 100% stock and I mean STOCK!!!! That was cool for me because I got to see what it would do from stock to when I got my stuff done. Below I will show what it did stock and then what I did after and what it did then. I hope this helps some people see some differences. On the modded side all the parts are brand new and the swap and tune and break-in period of driving and going to the track to test for after results were all done in a month!!!

And I know I'm holding some tenths back. I think with a better DA, driver loose 50lbs (lol), put the DR's psi maybe down to 15psi, and a better intake for the cam and the air supply it needs after 5,200rpms maybe just maybe 11.3-11.5's????????
Oh and this is all on Chevron 91 octane pump gas here in California.

Wow...crazy. Crazy numbers! With that MPH it seems to me you are probably making way more power or race weight is lower than the scale said?
I mean generally cars that heavy need ~50-80 more rwhp to trap that high.

I went 11.13@123 with a stock fuel pump,and 42's. Congrats! Great times the 120mph is killer for that weight. My car was #3230 with me in it on the scale at the track,at a scale close to home it was 3180. So they do differ in weight. Im curious to see if the 102/102 helps. I bought my 102 because the 92's were all but gone,and it was the same price if not cheaper.

Patroit Performance Stage 2 "243" P&P CNC'd Cylinder Heads
No problem with piston to valve clearance? Are the valves in the 243's recessed into the head?
