From my experience, not really. It will raise your stall, but I'd run it.

Thanks Chip, When I sprayed my smallblock I had a tighter converter and it increased the stall quite a bit. I will give it a shot. I don't think it'll hurt anything, it just might not be optimal.

the first hit would be a 150 hp hit off the line with a 250 hp hit in 2nd gear.

motor is built for nitrous with forged pistons and proper ring gap.

I was told not to do that by guys that know a lot more about nitrous than me. You need a separate regulator for the 2nd kit. Not only to set the pressure for just the 2nd kit, but b/c of a supply issue at the regulator.


ok, thanks. Thats the kind of info I was looking for. Should I put in a "Y" after the blue pump to another regulator, or a "Y" off the tank and run a separate pump and regulator

fasteddie...I'd put a Y after the pump and use another regulator. One blue pump should be able to feed both systems easily.

The only issue I've heard of using a small pump like a Holley Blue deadheaded for the nitrous side is that when the solenoids open, the pump can't recover from the pressure drop as quickly as a big pump can and you can have a lean condition at the hit. Now, having said that, I know a lot of folks who have run setups like yours for years and never had an issue. I ran one too for a while, one dedicated holley blue to feed just a 150 shot, and never had any trouble w/ it.
It'd be ideal to have a return system so the fuel isn't sitting there banging against the solenoid until it opens.

Pretty slick tool for spark plug reading. If I ever get my car running and hit the button I may have to buy one of these.

I wanted to thank everyone for the help i get on a regular basis from this site Ive always got solid info and a bunch of different opinions.
Im making good progress on my build and now that the suspension is done and my placement of the turbos will work ive moved back into the engine bay to work on plumbing the turbos in. I decided to change how I initially had the hot side run to free up some space and I think its alot cleaner now. So I just wanted to share a pic

Looks good. Are you going to intercool?

No intercooler Im running e85 i do have a meth injection setup wired up in the car but I never used it with the turbo slant, but it will get plumbed in just in case. Im going to get the wastegates mocked up later this week I had to order a couple SS transition to mount them. The downpipes are going to be tricky but I think ill beable to run it how I planned and if all else fails I'll stub them up thru the tops of the fenders like Trendz suggested.

Save your money and your plugs. Just buy an "ottoscope" read the plugs and use them again. I use this one...http://www.medsupplier.com/adc-diagnostix-5211V-standard-veterinary-otoscope.aspx

Monte what's your opinion of the NX RNC single entry crossbar with the 375 solenoid ? They claim it flows a lot even with a -6 line

OK SO WHATS THE BEST OPTION?

.375 SOL WITH 10-15 DEGREE LAUNCH RETARD FOR ?? 1.5 OR 2 SEC
THIS SOLENOID PROGRESSES BUT FROM 50% ON , I KNOW NOT A LOT OF CONTROL OF IT

.175 TRASH CAN AND PROGRESS IT FROM 20 30% ?

are these plugs a good plug to run on a cheater plate with a .055n/.045f at 5psi,timing 30 total .ngk r5671a-7 or r5671a-8.motor is a dodge 340,9.8 compression iron head.currently running champion rc9yc at .025 gap.

We us the Ngk in my sons magnum 360 but we use -9 , watch the heat on the straps. Better to use a colder plug if possible

Maybe my question from earlier got overlooked?

When building a nitrous motor, is it better to use a bigger intake (extra plenum & runner volume)? Meaning an intake manifold that's too big for the motor in N/A form.
Seems like I've always heard the more plenum volume the better w/ nitrous.

I'm using a plate system, but it doesn't seem like this would matter as much w/ a fogger?

A solenoid with a pressure balanced plunger, which those .375s are.......will never consistently pulse at any percentage. Don't care what NX tells you.

A nitrous motor of any kind always responds to plenum volume
