How Much Nitrous...?
I've posted a few times before about running nitrous on a SER1 L67, but I realized most people haven't really had any experience with these motors. Today I hooked up a 50hp wet shot to my car with the stock pulley on and it responded quite nicely. I'd like to step up the shot to a 75, but I'm not really sure what the motor is capable of handling. Injectors aren't an issue since I'm running a wet kit. I'd like to know what the fuel pump is capable of supporting horsepower wise, although I don't have to worry about running lean since I'm running a fuel pressure safety switch.
I remember there was another forum member with a SER1 L67 in a fiero and was running a 100 shot with a smaller pulley. I probably won't go that extreme. I'm thinking of either running a 2.1" Pulley with a 50 shot, or running a 75 shot on the stock pulley.
Any info/suggestions are welcome.

75 shot is the most anyone has run here, and few have. We try to stay away from nitrous.
I suspect you'll have major problems with KR, even with the nitrous if you step to a 2.1" pulley.
The stock Series 1 L67 fuel pump in GOOD condition (new) is capable (believe it or not) of supporting more than the Series 2 L67 fuel pump. Ours is good for 400hp.

Welp at least the fuel pump should be good for what I'm doing then. I ended up running a 2.1 pulley and a 50 shot last night. The outside temp was 62 degrees and I raced my buddies supercoupe for comparison. He has intake, exhaust, gears, and 10% pulley. I pulled about a car from the stop and stayed there. Then we went from a roll and he pulled about a car and then stayed there. I was hoping to do a little better than that, so KR probably is an issue here. I'll swap back to the stock pulley and put a 75 shot on it and see if it performs any better that way.

I have been running 100 shot for almost a year now. I am running walbro 255lph fuel pump it handles the 100 shot great , I dont care much about the series1 and am swapping out to a series 2 shortly so I will be trying a 125 shot very soon, and continue to go up from there. motor has 75k miles hate to toast a good motor but we will see how much it can handle with stick injectors etc.
