to run a 150 wet shot, all you need is a larger fuel pump to be safe. nothing else? will the stock Ls1 clutch hold up? thanks for the info.

I'm running a 180 wet shot with no upgraded fuel system and I'm running WAY too rich (a tuning issue I need to work out). So I think that's all a myth. I'd say you're good to 200 without upgrading, but that's just me. Read my disclaimer in my sig.

Always err to the safe side. Start out with a small shot, tune and work your way up. There are people out there running a 250 to 300 shot on a stock shortblock. Personally I think it's crazy but it's being done. Crazy is fun too.

Is this 180 rwhp shot?

I'm sorry, my mistake, this is 160 rwhp, I was wanting to run 180 rwhp but didn't have the jets (this number stuck in my head for some reason).
I started out using 65/35, but was too rich. By the end of the day I was running with 65/31 which was still too rich.
I'm pretty sure the rich condition is a tuning issue (everything usually is). I believe it's because I used the IFR table to get my fuel trims slightly negative (newbie tuning method, which I never changed after learning more about tuning) instead of using the VE table. But that's discussion for another forum.
i would add the fuel pump to be safe. i have a h&c car w/tnt 100 shot,all i did was add the 255 pump. or a better way to look at it is...if by some chance you blow the motor,do you have the $$$ to build another one. safe is better then sorry.

i couldnt agree more.Sam at TNT(the owner) told me straight up;"DONT RUN THE 150 JETS IF YOU DONT HAVE THE 255-LPH FUEL PUMP!" Strictly because TNT crams SOOOO much more fuel in,that the stock pump will be maxxed out and MIGHT not be able to handle it.i agree, rather SAFE than SORRY.

Good info. I am thinking about spraying a 175 ( at the flywheel) shot with my nitrous work kit. How much pressure did you have in the bottle when it was 75% duty cycle. I sprayed mine with 650 psi and i was at 89% duty cycle. Maybe it was high because of the pressure not sure. I am going to use a 62/ 35 pills and see what happens. The difference between me and u is I dont have any tuning. 12's or bust I guess.

Magic chicken: How much pressure was in your bottle when you had 75% duty cycle on your injectors ? Since I had 650 psi in the bottle do you think that might be why my injector duty cycle is so high on a 125 wet shot ?
Thanks for the input.
