Default Nitrous Setup Question

My nitrous system will be in as soon as i get the computer tuning issues resolved.

I am considering 3 setups.

1) 100 dry shot.
2) 100 wet shot on stock fuel system
3) 100 wet shot with fuel system upgrades.



For # 3, I am considering either an inline pump or a upgraded intank pump. Im not sure how the inline pump would work considering it would be sucking through the stock pump.

This is on a '98 with stock injectors and fuel pump. The car has a hotcam, are stage2 heads, Mac headers and orp and, it is running 116 mph in the 1/4 on the motor right now.

With your current setup and HP levels I would most definately go for #3. That would be the safest route by far and also give room for future increase of HP levels.

So I guess the old saying of you can never go overboard on building your fuel system is correct in this case.

Oh yeah...forgot to add like Rich said...take the time and do the intank pump. It will be worth it in the long run.

Thanks for the replies....

Looks like I have some work ahead of me!

Does anyone know the stock specs for the '98 pumps? I figure I will go up to a 255lph, but I am curious how much of an improvement that is.

Nevermind...the search button is a wonderful thing.

Looks like the '98 is rated a 114 lph.

Just make sure you research the aftermarket pumps also. The Walbro 340lph pump is enough pump for a decent shot of go-juice, but it has been reported to affect the N/A performance. The Racetronix looks to be a nice easy simple upgrade. The twin Walbro 255lph pumps modified by ARE seems to be a good pump set up too.

FYI ...the twin pump setup is a Racetronix product as well <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

At the HP levels you are contemplating you will require an external regulator system up front.
A single GSS340 with PnP harness might get you by.
You can always add the voltage enhancer to the setup to boost the single pump by as much as 30%.
