So my car n/a around 335-350FWHP - has 24# injectors and - good for up to 358HP according to the chart. If I up the fuel pressure to 70 psi, I will be good/safe for a 100 shot up to 474HP...BUT..without the nitrous on, isn't it going to run like crap??

if you get a wet kit it doesn't matter, because the fuel is being supplied by n20 system.

and dry kits only bump up your fuel press when your spraying

Until you get to a BIG dry shot. I have to bump my pressure manually to run the 125 shot. I crank it up to 43 and the car doesn't run too good N/A like that.

100 shot I let the Zex kit push the difference. If you want to go BIGGER than 100, I would look into a wet kit.

Go WET. like was said it sprays the fuel with the n20,

Oh! I did not know that. So there is no need for an adj fuel pressure regulator then right? The only thing you really need to do is adjust your timing and get a larger fuel pump right?

With a wet kit all you need is a good fuel pump. No need to change the fuel pressure or anything else.

I'd get a wet kit.

I really don't want all those solenoids on a wet though ..and isn't a dry kit easier to install? Also, are you saying with a wet kit there is no need to adjust timing at all? Thanks.

IMOP wet kits are really not that much more difficult to install or place noids than a dry. their are some kits that claim if your engine is stock and your running stock timing, you don't have to change it. that just means you should have been running more timing NA. I recomend about 1 deg per 50 shot assuming you got your timing curve nailed down already. down't forget to run premium and drop down your spark plug heat a few ranges

Ok, thanks.

Stick with a proven/cheap used nos 5115 Dry kit. The kit spikes the FP, you do NOT have to manually change it when you wanna squeeze. I've had both and my dry kit was better. A 255 high press pump is a smart move.

With something as volitile as nitrous oxide, I would stray away from a used kit. Buy new...it is still cheap in the scheme of things.

Zex has a wet kit.... it's tiny compared to the old dry kits like I have. All solenoids are in the box too. It would actually be EASIER to install than my dry kit was, just because it's smaller.

How does the dry kit spike the pressure?

Not sure on the NOS brand, but on my Zex the box basically splices into the vacuum line between your intake tree and the fuel regulator. It then bumps the fuel up when you start spraying the juice.
