Will I need a new fuel pump?
Will I need a new fuel pump? Im looking at doing nitrous in my 00 WS6. First, with everything in sig, wet or dry?Which kit? How much with forged internals?
Now for the main question, will I need a new fuel pump to even think about a nitrous kit?I was planning on it sometime in the future, but havent done it yet. Would a 75-125 adjustable shot be too much for the stock pump?If my stock pump is ok to use, should I be looking at a wet or dry kit?No direct port, no intake for it yet.
Where would be the best places to spray a wet or a dry?Lid?B/W MAF TB?B4 MAF?????
Thanks for all the help in advance

You're in new fuel pump territory. Take a look at the Racetronix systems, they are good for 600 out of the box, and can be pushed 700+ with a BAP.
Wet or dry is harder to answer. My suggestion would be to do a search and figure out which way would be a better fit. I have a feeling that you may start off with a 125, but with you bottom end built you'll want to go on to a 200 or more shot pretty quickly.

im no expert, but from what i have heard, the stock pump is good for around 450hp. with those mods im guessing u are somewhere around 400, so a 100 shot would be exceeding the capiblities of the pump, at least with a safe margin of safety. one thing that would determine if dry is even an option is to determine what duty cycle your injectors are at at WOT with what you have right now.

Ive done some research here and have found many opinions, not sure of a correct system came up. Will a wet kit work spraying through lid, or somewhere in that area?Wet would be nice for the extra TQ that comes with it. Which is harder to tune in, or is it a bolt up system and run kinda thing?Im new to nitrous(with my own cars) but have been around it and know some things about it, but now considering it on my baby,I want to make sure I know ALL THERE IS, so all the help is great
VENDERS WELCOME TO HELP AS WELL
Thanks Matt, further imput throught here or PM would be great as well
I was wondering about this too...
Is it possible to test the pump to see how good of shape its in, what are some numbers to look for?
Heres a good article on testing fuel pressure
http://www.findarticles.com/p/articl...05/ai_n9271473
Im at 375hp and looking to do a 100 wet shot. I know this is on the edge so Im trying to figure out a little more info.
What about adding an inline pump to boost the fuel supply a little, how would this compare to a new fuel pump?
Are in lines reliable? What are some of the pros cons?

I hope I am over 400 HP!!!need to hit that dyno soon....I know my injectors are fine, I have 42's.
Input anyone on the topic at hand?read through the posts and let me know what everyone thinks.
The easiest way to test is also the riskiest way. That is to hook up a fuel pressure gauge and watch the pressure when you spray it. A good rule is if you're above 350 NA and want to spray a 100+ shot a fuel pump is a good idea. At the very least it's cheap insurance to keeping your motor together.
I don't recommend running an inline pump. It's a band aide fix to the problem at hand. How is an inline going to support more volume if the limiting factor is still in front of it?

No, a wet kit will have to be sprayed post MAF. A dry kit is positioned pre-MAF. As far as tuning in A/F I find that wet kits have a bit more of an edge over dry on LS1s PCMs. It's pretty easy to just swap jets out instead of playing with tables in edit/tuners.

I agree with Matt about the inline pumps. I personally don't like them because, like Matt said, they are a band-aid fix to the problem. Plus, they provide the chance of cavitating the fuel line and completely cutting off the fuel supply.
I have seen guys using the stock pump make some ridiculous hp/tq numbers (way more than most people think is possible) without any drop in pressure, but then again I've always considered an upgraded pump just part of the equation in modifying a car. It's something that you can do now and not ever worry about it later down the road.
