What times/horsepower would you expect from a stock m6 ls1 with a 150 shot??

 

Well, you didn't say what year the car is?

The 98-99 LS-1s have less advertised HP than the 00-01.

With that being said here are AVERAGE #'s...

a 98 LS-1 M6 should be capable of 13.6-13.9 @ 102ish.
ADD a 150 shot and you got 12.1-12.7 @ 109ish.

an 01 LS-1 M6 should be capable of 13.3-13.7 @ 105ish.
ADD a 150 shot and you got 12.0-12.5 @ 113ish.

Either way, it is capable of going 11's in the right conditions.

Good luck and get some sticky tires to harness all that HP to the ground!

 

i plan to use a 150 shot ... most stock ls1 cars run about 107 through the traps so id hope id be going faster than 109-113

 

I know 2 guys here with stock LS1s, (a lid and muffler), and they both have a 150 shot. 1 runs low 12s @ 122. The other usually runs 12.4s @ 115, but his best has been an 11.4 @ 118. Don't know why the one car traps so high, but it freakin MOVES. Both are A4s so I'd hope that any LS1 would run at least a 12.4 @ 110 on a 150 shot. There are LT1s doing that.

 

Not an M6 but my 00 went 13.24@104.85 stock ,on stock tires and everything.
Then added drag radials and ran the same times on the motor but also added a 150 shot of go faster juice and ran a best of 11.78@115 with a 1.72 60ft.(everything else stock except NGK TR6 plugs for nitrous)

Then added stall convertor and E/T streets ,long tube headers and custom y-pipe and ran 12.7@108 with 1.72 60ft on motor .

Then same 150 shot i ran 11.60@119 with a 1.56 60ft with the wheels off the ground.
LS1's really like Nitrous!!!
