Now when you say corrected, you mean that you corrected it from hp to the crank, to hp to the wheels?TT_6SPD_95 said:Well, I have done 486 (corrected) at the wheels so far w/o the use of nitrous so the injectors are ok for that amount of hp.
I am using a wet system on the nitrous so mainly all I need is extra fuel going to the fuel selonoid to flow 50-100 shot of nitrous...thats all I want.
I am not sure if nitrous takes less fuel to make the same amount of hp that making the hp on turbo alone would so I am not all that sure that the stock fuel pump will handle this kind of flow now if I try to spray it.
I did 486 RWHP "off the bottle"
I want to do ~586hp "on the bottle"....need to figure out a good way to get fuel to the wet setup of the nitrous.
You have iridium spark plugs.deavenly1 said:IM INTERESTED IN THIS ALSO, I TRIED TO SPRAY (50 SHOT) AND THE CAR HESITATED AT BOOST, I DON'T KNOW IF THIS WAS DUE TO PLUG'S OR INSUF. FUEL DELIVERY?
DaveH said:Ok, since you are using a wet system we can eliminate the fuel injectors from the mix. At 580rwhp you will be exceeding the stock fuel pump capabilities. I would add a second pump and wire it off of a relay. Change your fuel filter (if it hasn't been changed recently) and your fuel line will be fine. Get a FPD Bypass kit with the tee in it to run to your nitrous solenoid and you are set.
A 100hp shot is pretty big for the stock twins, it wouldn't surprise me if they don't last too long.
What would you wire the relay off of to turn on the pump...boost pressure or maybe fuel pressure? I could run it off of boost pressure but I guess that might be bad if I am not running the nitrous...I guess I could put an override switch for the fuel pump though to make the pump stay off. Thanks for your comments, they are really helpful.DaveH said:Ok, since you are using a wet system we can eliminate the fuel injectors from the mix.

At 0psi I run 43lbs of fuel pressure and at full boost (~20psi) it runs 67lbs of fuel pressure. That is a little more than 1lb of fuel pressure for every pound of boost, but that is how it is in my car. This info was attained by replaying back the defi gauges peaks and seeing what exactly the fuel pressure was against the boost pressure.Zerosoul said:Tony,
off topic, I was wondering what fuel pressure you are running at idle, 0psi, and full boost again....you gave me those #s before but the new server deleted old posts.
thanx!
