I have a 98 Cobra with an 03 motor. Pushing around 450hp to the wheels now. Came across a NOS wet kit with all the goodies minus a bottle warmer for cheap. Comes with a 75,100, and 125 jet. Window switch, purge...etc I was just going to use the 75. Of course I'd get it tuned. I have the right plugs. Stock 03 fuel system is in the car. The question is, how safe is it to run juice through the blower? Does it still work as well? Any other safety concerns than any other vehicle? Thanks.

Well I just mean running nitrous though the blower is no problem right? I've never had a blown/nitrous car.

blower cars pick up alot from spray. i recall someone on here making 500/500 with a ported car then spraying a dry 50 and making 590/640. i just sprayed a 125 wet shot on mine and made 557/594 in 95 degrees of heat with about 7 previous pulls (no cooling mods aside from a H/E). i cant wait to see how much i pick up this winter.

You will not have a problem with running nitrous thru the blower unless you have a poor tune for it.
Make sure you use good octane in the tank 93 or better on that 75 shot and remove at least 2 degrees of timing in the tune.

The one issue you will run into is that the fuel rail you tap into for the wet side of the nitrous will start to run that rail lean on activation only.
It's a momentary spike that some guys are OK with... I'm not okay with that so I run a stand alone fuel cell on my wet system.
This way I don't have to run a tune separate for the nitrous and worry about the lean spike.
Plus I can run a larger shot with the cell. I run 110 octane in the cell, 93 octane pump in the tank, and a 150 shot of spray with no problems on 14 PSI boost. Do yur homework and you'll be OK.

And you just put the nozzle in the intake like any other car? No problem?

Yes, before the throttle body but after the mass air flow meter. There is a fitting you put into the tube and tighten down. Then you screw the nozzle into that. You should start small on a wet kit and work your way up.

going on 5 years now that vie been on the bottle on my Cobra. Have run 60 to 125 and the car loves it. you will probably need a BAP and SCT MAF / MAFia though. might be ok without but it might be really really close at 500-520rwhp


isn't the car for sale?

I see you're flying with your set up? How much does your car weigh? Can you pm me your number , I'd like to speak with you.

I have 04 cobra with 2.76 pulley cai magma flow catback sct chip. Car has been tuned. It made 498 whp (I know sounds high ) anyway if I spray 100hp wet will I need a MAF? I'm planing on buying a bap.

if you didnt need a maf with the 2.76, you wont with the spray. THe car wont be getting any more air from the atmosphere, its getting the extra oxygen for combustion from the nitrous.

I think you are probably close to maxxing out the maf though anyways, i run a 2.76 and i am very close in cold weather.

definitely get a bap or a fuel cell/pump if you plan on spraying.

dont be scurred to run that 150 either... i have for a long time. car made 700 ft lbs

interesting.....I would say happy dyno though....or you have a much bigger jet

you'd have to make 550-575 on the Eaton to accomplish that on a "150 shot"
