I know there are suggested starting points when it comes to nitrous/fuel jetting, but does added compression affect the suggested (starting point) fuel jet?

I'm pretty sure not enough to alter it. I'm 11.5 compression and run a 52/28 for my NX 100 shot, which is standard

cool, thanks. I'm new to nitrous and just want to be sure before I go and screw something up with a stupid mistake.

Just pull a little extra timing and you will be fine.

This. Race fuel helps with the timing, as you already probably know. Higher compression doesn't affect the fuel jet size, but more timing will have to be pulled.

I was planning on pulling 4* for a 100-125 shot. Should I pull 5* for the added compression?

For reference, with my compression I ended up pulling 3 degrees for a 100 shot

What compression ratio are you running?

It's only 11.5:1

I'm also running a window switch. I'm running a larger converter that was designed for a max effort n/a setup. Do you think I should set the switch to cut out @ 6700?

I would set it to cut out about 200 rpm's before the rev limiter. At 11.5:1 I would just pull 3-4*per 100hp and go from there.

So you think I should spray through the shifts? The current tune is for n/a, I wasn't shure if it would bounce the rev limiter if I were to spray through the shifts.

My a/f was 11.8 with 3 degrees pulled for the 100 shot, and the pills were 52/28. You'll be fine at 3-4 degrees

That's where a window switch comes in handy. I would use the MSD 8969 on your application if you decide to go with one. Otherwise, you don't want nitrous spraying off the limiter. No bueno. Haha.

I only needed 4 degrees pulled for my 150 at 10.5 cr. I have nothing pulling the timing and didn't lose anything noticeable from being down the 4 degrees. If you want some help installing let me know, I would be more than happy to help.
