Dude,
I want to use the 200hp shot on my motor. I sprayed 3 times, but with the platinum plug and probably a lean tune.
Add that a almost like water oil, and the result was a cap busted.
What was ur problem with the Nitrous? I know the bottom end can hold it and have forged pistons and use only race gas when using NOS (110+oct), but is there a tune issue.
I have a wet ZEX system.
Have a walbro replacement pump in the tank and a Wlabro aux in line that Allen send me, have 42 injectors.
Check the presure at wot and check on 52-53psi all the time.
Can you lead the way?

From what I have been told, the walbro pump is good to 550 HP. If you're building more than that with the HP of the engine plus the desired amount of boost you need a larger pump to provide more fuel for both devices or a seperate pump just for the spray. That is what I am going to do next after replacing the the LSD unit. I want about a 2 gallon fuel cell and a inline fuel pump with it's own corvette fuel pressure regulated fuel filter feeding a consistant 58 lbs of fuel pressure to the nitrous kit fuel line. What happened to mine was I tried to make more HP than my fuel pump could keep up with. Definitely get a fuel pressure safety switch on that thing so that if you go under the desired pressure the nitrous will shut off. No need holing out another piston or burning the tips off the spark plugs because you're lean. Get the correct plugs, too. I had NGK TR6s when mine died but I still didn't have the FPSS or an RPM window switch installed. For what it's worth, one gallon of fuel is approximately 6" x 6" x 6" in volume if I remember correctly.
Don't forget to retard the timing back 2 degrees for every 50 shot of juice.

Readheart,
I have the Exact cross over on ur NGK TR-6 now, but in champ, thanks to the reference cross over you send me.
About the engine making more than 550HP I doubt it. My guess is between 380-420hp most at the crank!!!!!
By Allen instructions, I'll be testing from 100HP shot with a Fuel pressure gauge and the AEM WB O2 and then climb up as we succed with the tune.
Where can I buy that presure sensor to turn of the NOS?
-
If you make 420 HP at the crank and then want another 200 HP from the Nitrous, that's 620 HP fuel required from the 550 hp fuel pump. Hello lean burn and rebuild number 2?
dynotunenitrous.com or nitrousoutlet.com can fix you up with the fuel pressure safety switch.
-
Got it dude...no need to spooke me more!!!!! :(
Anyway I'm in the way of reciving my 60 injectors and my new cam so I guess I'll need a new more powerfull pump!!????
Checking the sensor right now
-
You have the choice of running the current pump to power the engine and add a new pump and fuel source for the nitrous or just add a bigger pump. The Walbros are only 255 litres per hour, not much. The GS340 they sell pumps only 255 LPH, also. I can't remember the larger pumps Billy uses. They're a little more expensive but bigger = better = more money. :eek:
-
Teh NEVER ENDING STORY DUDE....................moo money always!!!!!
-
How much is that Walbro pump and where is a good place to get it? How muck N20 can the stock pistons take safely? I have a TNT Power Ring that I'm thinking about using on my 5.3L Silverado. Thanks
-
Allen sells Walbros at NelsonPerformance.com or you may shop around. Be sure you get one that will work for your application. Do you need a factory replacement unit or an external inline pump?
Guys run 150HP shots religiously on the stock pistons but they've got their systems dialed in perfectly. If you run that much, be sure to install all the right parts, pieces and safety devices and controllers. You cannot be cheap on a nitrous kit unless you like rebuilding engines. To do it correctly you're going to spend at least $1000 on all the stuff you'll need for a wet kit.

I can get a walbro in line just as the one that NElson sold me here.
I decided to go with the separate fuel system for the 200 NOS
Remember that I have a Walbro replacement in tank AND a Walbro In line in the zone of the fuel filter.
How much Pressure pump do I need t the new pump for the separete NOS set up?
-
Run the same pressure as the fuel system. I will run the 2000+ Corvette fuel filter that has the built in regulator at 58 lbs that way it's consistant with my system. The trucks seem to run low on pressure at idle but boosts the pressure up under performance mode. With the stand-alone system you can do anything to your truck you want without worrying about running out of fuel for the juice.
With a fuel pressure safety switch installed in the stand-alone system all you have to worry about it too much bottle pressure or running low on nitrous. Too much, lean, too little, rich. I'd suggest getting an electronic bottle gage if you can afford one. My bottle is in the bed of the truck and I don't have time to get out and check the pressure. On a hot day I've seen 1300 lbs of pressure on the gage! I think you're only supposed to spray between 900-1050 PSI. Tune it for 1050 and let it be fat on gas should it run a little lower. BTW, Dynotunenitrous.com has a bottle heater with a FPSS for about $100.

My dad always say "he who listen advices live longer"
I'm going with the seprate system and tell you so step by step.
BTW, I' buy today the in line walbro for FI veicles that click on 60PSI that for real push around 53-55 most.
For the filter Can I use any filter for FI engine, like the the normal in the trucks, or the ones that just plug with clips? They also use a pressure around 50+ PSI?
-
Yeah, that kind of filter is fine. That is what the Corvette filter is, it clicks on. When you get the new inline pump, hook a FP gage to it and see how much pressure it puts out without a regulator. You may find yourself needing a regulator or the corvette return style filter(much less expensive).
-
You can always run a dual intank setup with a relay for activation
-
That last one sounded really nice!!!
Cause I was checking the place to fit a 5Glns plastic tank under the Truck, but as I always use racing Das for Racing and NOS use, I can set from the same OEM tank....!!!!!!
Any Ideas on how to this and Pros and cons?
-
Running race gas through an engine with less the 11:1 compression is just pissing money down a hole. You only need it for the high compression built during events like extreme boost levels with some kind of forced induction or nitrous blasts. The rest of the times you wouldn't notice any difference in your times versus pump gas. l've seen a lot of guys pissing and moaning about paying $10 a gallon for race fuel and thier times weren't any better than running on the regular pump unleaded.
-
Reasheart,
$2.5 the gallon here the 110 oct Gas
$2.18 the Gallon the 92 oct (that really is about 89)
$1.48 the Galon of Regular 88 oct (that really is about 85)
So in that matter I feel like I.m not throwing at all my money. mostly on daily driving issues I mix some race and "92" oct gas.
For Racing only 110oct (imported that's why I thrust Oct numbers)
My Truck is Build on 9.4:1 Static CR.
About taking a line from the OEM Tank, there's some cons, pros?
-
Is that 110 octane aircraft fuel? Aircraft fuel is rated differently and it contains some additives to introduce oxygen into the fuel mix for higher altitudes. The true R+M/2 formula we use here in the states isn't used for av-fuel.
I don't see why you can't tap into the stock tank for fuel but I don't know about tapping into the stock fuel pump to feed fuel for both pumps unless you put a boost-a-pump or boost the voltage up to a solid 16v at the pump. That would give you more volume for the in-tank pump.
-
Redheart,
I'll Go for the separate platstic 5glns then!!!
No AV Gas...here is leaded and cost $6.00 per galon and yeap, it has diferent quimicalls to induce oxigen at higher altirudes, but as uses in Boxer engines like the Cesnas and Robison Helicopters, the roof of those air crafts is not that high!!!!!!!!!& #33;!
There's a Avition mecanic around here I think.
Here the Company has have a 98 Cessna SkyHawk and a 2001 Robinson R44 Helicopter.
So I guess putting AV Gas 100/130 will induce more heat to the combustion chamber maybe!!!!!! or something like that!!!?????
We use here VP Racing fuel that a friend brings from who know where!!!!!!!????? and don't care for the price.
-
I think I'm going for the 3 gallon aluminum tank from www.summitracing.com. They have a blue tank on sale for just at $100. I'll pay the little extra for the raw aluminum tank.
-
The platic 5Gln is from a boat and is for free, and is the same model I use in the camaro Trunk!!!!!!!
I just need a place to fit it on!!!!!!!!!
