Fuel press ???? NOS
 

I need to get 85psi of fuel in my fuel rail. Right now I have 70psi. What is the best way to achieve this? I am going to make my system 150hp but it takes 85psi.

Why not come play with the big boys and use a wet kit. I just plain don't trust dry kits when it comes to that much hp.

But if you insist, you just have to get the right jet in the nitrous T that has the vaccum line going to the FPR. But if that still doesn't do it, you may not have enough of a fuel pump to do it.

FYI, I switched from a dry kit to a wet, and on the same "shot" jettings, I went 3-4tenths faster.

just a thought

What size fuel pump is in your tank? I to run a dry 150 shot...I have a 155lph intank pump + an MSD 200gph inline pump. That assured me plenty of fuel volume as well as consistent pressure. You may be able to achieve your 85psi. with just a 190 or 255lph intank...and not have to run an additional inline pump...but I couldn't say for sure. Back when I bought my 155lph pump there really weren't many bigger fuel pumps out on the market...so when I stepped up the the 150 shot...I had to get the inline pump too.

I used to run a 255 intank with a 150 shot. It was too lean. It had the fuel pressure, but the volume was not adequate.

You will either need the Walbro Gss340 high vloume 255 intank, or add a booster pump like the T-rex from Vortech.

I run a 255Lph intank pump on 24 lbs. injectors on the same shot and run just fine....@38lbs @regulator near perfect mix.
