N2O is armed, I'm in second gear at 3000rpm, I floor it and in less than 1 sec I have to shift to 3rd (105 shot is F**king awsome) when in 3rd gear it boggs and wont go any faster. I think fuel pressure drops and the fuel pressure safety switch kicked in, shutting the n2o feed off(n2o jet - 52 and fuel jet - 35). I know the fuel jet is high and making it rich, but it gives me piece of mind that its not lean.
So I'm guessing I gotta do one of two things:
adjust the safety switch to kick on at a lower fuel pressure (scary)
or get a better fuel pump.
The car runs fine without n2o. What do you all think?

what's your A/F at through 2nd and 3rd? The meters aren't super accurate, but do you get a spike in either direction at any time?

Dunno, don't have an A/F meter in, nor a dyno nearby.

thats cool bio, sorry for the loss, i read your other post. but thanks for doing some research into n20 at 105. not too many people have balls to this. by the way, i think it said u went 14.4 at 50 or 75 shot, have u ever ran the quarter at 105 shot?

Thanks, 75shot @ 14.4 on 17" rims and crappy tires.
On 105shot I have not ran in the quarter yet.
Guessing 13.0 to 13.5 with 15" drag radials and my setup.

I'd get a new fuel pump, Comptech sells an in-tank pump designed for the Supercharged S2000, I'm pretty sure it'll work for the Si too.
