Like I said that is just where the idea came from that is just how he ran it back then maybe he could have done it diffrent. Here is the only problem trying to get more fuel out of a blown through carborated setup. If you get it so it dumps enough fuel down the venturis at wide open boost you are pig rich down low in the fuel curve. When you dont have so much boost. You dont have the luxury of tweaking the fuel pressure or modifying the computer to make it just perfect all the time like we do. Lets lay to rest the arguement if he was doing it wrong or right with his car and move on to if it will work for our cars and give the advantage of lowering the boost which will inturn lower the potential to blow our junk up. That is why I brough the idea to the forum.

"If you're looking at using it for the power gains, why not just inject pure Nitro, or a higher nitro:meth concentration to boost the power even more?"

The reason is that you dont want to blow up your stuff. I am looking at useing this setup to get my car further from the edge of blowing up and haveing the fail safe of when the mix runs out the engine does not go lean. Yes you probably could run the concentration up and get even more power but you are just creeping closer and closer to the edge. We have whole barrel full of parts at the shop that shows what happens when you get to much nitro and go lean. I will lay it out this way if you mess up the mix, get stupid and get greedy for the HP with nitro you will not just burn pistons you will jack the head right off the motor and like your ARP head studs where not even there. That is if the rods and the bottom end dont give up first. Yes if we put our stuff on a dyno and put egts in all four cylinders were going for every last bit of HP we can squeeze out or the nitro injection setup we could probalby put more nitro to the mix. This being said it is something that needs to be creaped up on and not the guy on the internet said he ran 40% in his injection I think I can do that. I know it was a long winded answer but that is why we dont want to get greedy with the nitro. That and for all you guys know of me I might be full of BS. I will have this setup on my omni if I get a chance between races this year. I will assure you that it will work but like I said you dont know me from adam. If you are scared to try it...dont...but I will keep you all posted on the progress. On the other hand if you want to try it I have all the resources to help you with your setup. Especially if you bring your car up to Memphis.

I also apologize for sounding mean or sarcastic but I dont know most of you guys and you dont know me. I just want to make sure I am comeing across clear. The computer gets in the way of most peoples BS meter. I just really busy most of the time. Like tormarrow we are leaving Las Vegas and will not get chance to get on here for three days or so. Sometimes I get going and dont get to post for weeks. I will say I have done my homework. I will not steer you guys wrong. If you feel the need to get to know me or just want to shoot the shit before you try out my diffrent ideas give me call at 509-679-0765. Either that or we will be testing out in Vegas this weekend. I will also be at all 23 NHRA races this year putting the head on the Knoll Gas motorsports car.

Don't worry sarcasm comes with the board!

As for my findings I found that any mix above 2% would start to fall out in four days i.e. settling.

Nitro: specific gravity: 25/25ºc 1.124-1.129

vs.

Methanol: Specific Gravity @ 68º F .795

If you do not use a "binding" agent of some sort (an inert filler that is molecularly sticky) you get fall out.

Nitromethane has less BTU than methanol or gasoline BUT is does release oxygen upon ignition thus fueling the fire itself. I could quote scripture but, you seem one to read and learn.

Be mindful of how much you nitro you add to your mix! If you add say over 10% and do not add a good bit of timing you will destroy turbine wheels or explode exhaust manifolds. But its damn cool to do though!

I may give you a yell on your # sometime and shoot the bull.

MSDS's for the two fuels. Buttloads of info to use there.

I will be talking to my friend in the next couple days. I will see if he ever ran into the same problems. The only thing that I dont know about is if the upper lube that we mix in the nitro would help keep it from settleing. I also would say that even if we have more then 10% the size of the jet and pressure would make a large diffrence. As he was using a 70jet on his at 15psi on his V8. This is why I brought the idea here. I dont know a whole lot about regular alcohol injection. What sort of jets are guys running with the setup. What sort of line pressure is an alcohol injection setup running. What sort of volume of alcohol to boost are people dumping in. I will ask our crew chief a few questions about the nitro this weekend and get a little more info for us.

TFMech · **Ah you are right**

It does sperate with or without upper lube in it. The upper lube doesent make a diffrence in the seperation. What do you guys think about running two tanks one for alky and one for nitro. Then use a fogger nozzle, just putting a smaller jet in the nitro side to get the mix right. I think this setup will work but it will not be as safe as mixing it. Either that or add a circulation pump to the fuel cell. Anyone have any input.

I've been contemplating trying this for a while now. The problem is I cannot find any locals that sell nitro or have experience with it. So I plan on using RC car fuel. Next issue is with the castor oil, how bad is that stuff for the nozzles and combustion? I can find 10-30% mixtures but I haven't looked into it very thoroughly yet. I believe there is also 4stroke rc engine nitrometh available. God know's what that will cost.
Next issue is how much timing to add. I am currently running an Htrim stage 3 .82 at 22psi and making about 400rwhp using a shurflo pump, autospeed progressive controller. I've tuned for mid 11 afr's. I can run 28deg's advance with no detonation. How much to add for nitro, what egt's am I shooting for? The car is not a turbo mopar, but the same principles should apply.

TFMech · 02-08-2007, 12:16 AM

I would stay away from the R/C car fuel and find the real thing. The oil will just make it more prone to detonating. You really will not need that much. Usually if you hang around a race track you can run into someone that has or can get nitro. As far as egts you are looking to run the same egts....aluminum still melts at the same temp. You also want to start with cool egts and creep on to it. This is really a slow trial process start with a little and make sure everthing is right then move to a little more and so on. The idea here is to get you car tuned till it is running right on just gas or gas with alcohol injection. Then turn down the boost and add nitro sparingly into the alcohol injection.
