Hi Lamont,
Sorry it took so long to reply. Been at the track a bunch as well as offshore fishing the last 2 days. Was really good seeing you as well and glad you enjoyed riding the chopper and playing with the nitrous. Thanks for the nice remarks.
Lots of things to talk about with nitrous. Someone (I believe Jeff) mentioned the Sniper system. That's what I'm using. Good value and enough (up to 150 hp) for the bikes. I wish it had the jet setup in the line by the solenoids like the CompuCar system. Easier to change jets that way vs at the plate. Easier on the chopper cause of the open access and lots of room. Don't have to mess with moving the tank as on the Hoss but once you settle on the right jetting combo, you shouldn't have to mess with it.
Speaking of jets, Gary and I are at 100 horse squirts. The choppers have the hyperteutectic pistons unfortunately and anything over 140 horse is going to crap them out. Have seen quite a few non forged pistons go to crap from too much nitrous. In our case, the 100 horse is just right. We're not into smoke shows these days but rather best times at the track and the balance of gearing, weight and nitrous application are very important. We kill the notrous bigblocks because they're using a 150 or 175 horse shot and the tire goes up in smoke with little linear acceleration. Bottom line here is if you have a need to go with more than a 125 horse squirt, you need forged pistons. The other bottom line is too much of a good thing can be too much. Speed/time....not tire smoke, at least for me. A single rear tire can only accommodate so much hp. Trikes, a different story.
Adrian's bottle comment is exactly what I do. Sniper system came with a 10 lb bottle that is my fill bottle. I bought two polished 2 lb bottles, Gary uses a single 2 1/2 lb. They are identical in diameter but different in height. Freeze the polished 2 pounders, but your big bottle in front of anything that will warm it a bit, and whooosh...you're filled. Be sure to weigh them as we have often overfilled blowing the safety when guessing volume. Thank goodness for paintball gun spares.
On a similar subject, you may have some problems in your neck of the woods as the colder temps mean lower pressure. Unless you have 900 lbs or better, you aren't going to get the bang you want. Sometimes it degrades performance if the pressure is too low as you're getting a big addt'l gas squirt but not the right volume of nitrous. On the trike I used bottle warmers (fantastic) and would heat it to 1,100 lbs +. The more pressure, the bigger the jolt. Under 800 lbs it's a total waste.
On the Edelbrock and NOS systems, those small solenoids are only good to 175 horse. If you want bigger jetting, you need to go to the bigger solenoids. There is apparently a lot of discussion on single plane vs dual plane intakes and max nitrous hp but I've seen a number of the local guys using up to 250 hp on a stock Boss intake.
On the solenoid issue, I know a lot of guys use the horn button as their trigger. It's a cheap ass switch and I've seen some spark at night and know for a fact it's not the best method for your trigger. Some solenoids (Compucar) are very sensitive as far as electric and without a relay, the solenoids are apt to be intermittent or not fully open. Careful here. I personally recommend a high quality switch for your trigger.
Be very sure when you're doing the plumbing that you include a filter on the gas side, and watch the teflon taped getting anywhere near the fitting ends. Nitrous flow with gas restriction = puked motor.
We run seperate fuel pumps devoted to the nitrous system. Again, part of the above equation. I also like seeing a fuel pressure gauge.
We do not use a micro switch where you have to be at WOT. Tom Breedlove is one to talk to here. What he can do with his bigblock and the real quick squirt while cruising Main Street is incredible. That bigblock revs faster than any smallblock during his fast gun-ups.
I'm sticking with the real clean, simple look on the chopper. I don't have the nitrous controller (computer) and for the fun stuff of jucing it on the street don't feel the need for one. For anyone serious though and especially for the track, they're awesome. If you have room, love gadgets, have the extra bucks, and want the very best performance with your nitrous system, controllers are the answer.
I couldn't run at the track Friday night as my headers are off being modified and I haven't chucked my damn Demon and put the new Holley on yet. Gary had major carb problems and a bad fuel pump but in spite of those woes, his first run was a 6.48 @ 118 mph. We feel certain that once we get rid of the Demons, run the new EK530 chains, and a few other minor tweaks, we'll be running much lower 6's.
Again, great seeing you in Daytona and hope you get your nitrous system soon. It's definitely "you" Lamont. Best regards,
Elliot
