How much will you lose on a drag truck if you dont run a IC, but run nitrous?

i know it doesn't anserw everything but could you not monitor air temp just befor the motor and then ditch the IC and compare?

IMO i would get rid of the IC with the NOS your using there is no need for it and you will have better spool up.
 
what brand is the best. The nitrous express kits are the nicest looking, but the ZEX kits seem to be best bang for the buck. Any advise?
 
Best bang for the buck, piece one together yourself. It can be done better and cheaper than most kits out there.
 
Id love to do a progressive controller, but, i dont see that happening.

what would you recommend for a parts list.

Yep.

Working on building a plate system right now, should come in much cheaper and better than any of the kits out there.

What are you looking for in a progressive controller? You can easily set up a time based PWM controller...

progressive based on boost
 
Purple bottles are a great value, and i beg to differ that you can peice one together, lines and soleniods are expensive, and depeding on how big of a shot you need to make sure the soleniods are big enough.

If i remember right there is a dude out of florida or texas ( i cant remember) that goes by nitrous dave and he has some of the best prices on nitrous controllers. Ill do some more digging though.

I think this is him, his site looks different though...Nitrous Outlet Nitrous Accessories
Nitro Dave's Performance
 
theyre regular kit looks pretty nice, good price too, I still cant spend for the progressive controller.

I cant decide if i want to run single or dual stages now LOL

Honestly two stages works pretty well, and it should be "progressive" enough, though i might be wrong

how much nitrous do you want to run?

It depends on what you're looking for. It may very well be a wash if you're looking for a basic setup, but if you want something a little more complicated or out of the ordinary then building the system yourself is going to be the way to go. The plate system I'm working on should come in at about half of what similar kits would go for.

Great point. I guess i should have been more specific.
 
When I first setup my kit I ran a small shot .047 solenoid on a WOT switch. I then had a bigger shot (.125) on a button that I would hit after I hit second gear. This was on a -4an line. There was definately a hit when you hit the button.. I like the progressive controller I have now, works very nice. I think that it will (over time) save its purchase price in saving parts.

Agreed depending on the shot.

im thinking a 50 shot at 10-15psi and another 50 at 30-40 psi

ill have to figure out the jet sizes but you need like a .048 in the first stage and around .099 in the second to make it work right, i need to find the formula for calculating jet sizes with more than one jet.

im assuming you mean to run the 1st stage from 10 to 30 and the 2nd from 30-max

i think im just going to set them up to run 10 to max and 30 to max, both around .035's to start

No actually i mean run the first stage of .048 then run the .099 the combination of jets only equals like .110 i think...
 
I ran a 50hp shot, .036 jet and it didn't do anything lol I put an .052 on a push button and that jet seemed to be what the motor wanted. IMHO if you have the fuel and a big single, I wouldn't run anything smaller than a 80hp shot for spool up. Mines likes a 100hp at 10psi. But that's just what worked for my set up

Agreed, some kind of controller is a good idea if you're looking at dumping a bigger amount of nitrous into a motor. IMHO, a lot of parts get broken by dumping a big shot of nitrous into a motor all at once.

Think that is how your motor died?
 
Well now that I have had a chance to disect the motor, I am really starting to think that I had a catrophic chain of events. I think I added a little too much timing, coupled with an injector sticking open slightly, not enough boost, too much nitrous...... BOOM. It definately ignited while the piston was on the way down. The head and the top of the bore were not touched in any way shape or form. But the bottom,, wooo it was a mess
