One practical revision was done - and that is to run the charge valve and gauge out the rear where it can be accessed with the body on, to facilitate re-charging the system after a run without having to remove the body. I considered moving the tank and switch to the rear as well, but it would...
So, the jury is in on this setup, it works extremely well. (see the "Hissed Off" thread for a recent video that demonstrates it vividly) Here is one that is fully finished:
Note, I did replace the purge valve at the bottom of the pic with a better one, as those plastic ones leaked, slightly...
Started on another one last night. Waiting on the gauge to arrive to finish it.
The system as shown with what is on the car during a run, weighs in at a whopping 2.8 oz :D That's pretty light given the power increase. The key to this system is that the cartridge and regulator don't need...
Radio switch. In theory you could hit it off the line (wouldn't recommend doing that with a big block), and let off the button, and hit it again if needed. It packs quite a bit of NO2 in the expansion chamber.
Finished the system this weekend. Had beautiful weather on Saturday for testing, but I was short one (major) part, and didn't finish until last night. Next week looks like we have a chance for some near 60 deg temps on Saturday, so maybe then.
I did adjust the valves and test the...
While looking for some fittings, I stumbled across something that changes a lot of the design - pneumatic tubing/fittings kit for dental equipment, in 4mm OD size. Total game changer.
Much cleaner, lighter, and has zero swelling/expansion when charging the pressure lines. This presented a...
Was able to do a little bit of testing at long last :D
It wasn't warm enough for a true, full pass, but I did do some 50-70 ft stuff, at about 58 degrees last week. I typically refuse to do full passes under 60, simply because I like my car and don't want to cartwheel it when the rear tires...
Catching a weather break this week with a day or two in the low 60's, so I might have a little time to at least run the thing and see if it leans out. I already have the contingency parts on order. Rather than a fuel bulb which surely would inflate, I found a decently large, clear fuel filter...
Well I had a 3 day weekend, and I learned a lot. I must say, a lot of hilarity was involved :D
First, on the pressure side, well, you cannot use nitro line! It blew up like balloons. Ditto for the fuel bulb. So I inserted them into 1/4 inch rib tubing, creating somewhat proper pressure...
That's another good question. I haven't weighed the parts yet. They aren't terribly heavy though - and the bulk of that is the tank/regulator, which I put on the front where it's badly needed. So, I'm thinking it should, but won't know for sure until I get to testing in a week or so when the...
Way back when I first started my first nitro drag car setup, I had thought about adding nitrous to it, and was (correctly) talked out of it. While they "sort of" work (and you'll hear a lot of passionate, varied opinions on that), the implementation really isn't useful, IMO. Back in the day...
