Well I think I'll be pretty fine with 100 shot or maybe 125 but doubt that much doesn't really help my situation when you guys keep saying you went up and ended up blowing your motors. I don't want that yet got another project truck I'm working on too.

I'm getting all excited now hearing things that I WANT to hear. We should see when I'm done hopefully I'm not the 1% that got a not so good lt1 and create major issues for myself.

btw the nitrous is on a progressive system which is the reason the torque is lower, eliminated the torque spike

I'm spraying a 125 shot on top of the cam and other mods below. I have to wait about a second after launching before hitting the spray. If not I would never get traction and the rear would probably explode with sticky tires. New heads are going on in the spring. So far so good.

I have a racetronix in-tank pump with the hotwire kit. Injectors are nothing special but SVO #30's.

I'm doing a similar build 503, heads, N2O, etc. I have 30lbs red tops already, I was wondering is the upgrade to the bigger fuel pump a must? I was thinking the stocker would provide enough fuel & pressure for a 100 to 150 shot. But if not I'd like to know so I can change it out while the car is down.

my numbers were made on a stock pump, at the end of the dyno mine started to lean out where my pump was running out at 500hp. I would recomend a new pump for saftey.

I would recommend a new pump. My car is a 97 with roughly 75k and I just didn't want to risk running out of fuel or having a failure. Just good insurance.

FWIW, I'm spraying 150 on a stock pump.

The walbro's fail too, best is to have a FPSS installed so no matter what the cause, if fuel pressure drops, kit wont spray.
