I have stage1 kit, WGA @ 20psi boost hold redline running 262hp / 312 tourque. I just bought my nitrous kit and im wondering if the stock Fuel pump will support a 75 -100 wet shot of nitrous. Also, where can i put the fuel lines for the nitrous, some people say at the end of the fuel rail, others say near the beggining. Please let me know.

What is the maximum Flow of the Stock Fuel pump?
What is the maximum HP recommended on the Stock Fuel Pump?

Thank you guys for all your help for those who are generous. Thank you

 

For the price of a Walboro I'd just upgrade it anyways. Its so cheap it really cant hurt the car any, and it can help your cause. As for running nitrous Im not too sure.

But....Stage 1 doesnt really get along too well with boost that high. Nor does your intercooler. Your intercooler only flows efficiently until 19PSI, anything above that and its just not doing any good. If you intend on running such high boost, Id suggest a larger intercooler, at first you may see a loss of 2psi in boost, but with supporting mods youll sustain it, and in the end gain more out of it if this is the route your going. But definitely turn the boost down.

 

okay your running to much boost for S1. id turn it down asap. to like 17 and not to red line you dont have enough fuel for that.

as for nitrous the main problem id see is your fuel injectors not your pump. for a 75 shot id have at least s2 injectors on and it would be better with a fuel return kit.

 

I took it to the dyno and did 4 pulls. at 21-20 psi boost my air/fuel is 11.9-12.0. So i should lower boost, Get fuel pump, and i should be fine?

So....
- Turn down the boost
- Up the injectors to S2
- Fuel return line kit
- Fuel Pump is optional

And you should be set.

 

Couldn't say it better, myself.
