we made/make a 400 turbo that is 100% air operated here at our shop. We ran in it our pro mod car and also in Ron Muenks 63 corvette pro mod. Everything was air operated inside the transmission. first we just had it shifting with CO2 then after realizing 4 wheel disc brakes werent enough to hold the car back at a just off idle launch, we included a trans brake. With CO2 timers that times down to like hundred ten thousands, it was the fastest releasing transbrake in the world. Also fastest shifting transmission. that being said, yes air co2 operated stuff can be quick for whatever. Problem with the bruno's basicly thier design freakin sucks. Always leaking, tearing pumps up, customer service sucks (they wouldn't work with us even to get a pump), they are so touchy on pressures its retarded.
As for lencodrive and electric trans brake. You know we run in our dragster. The last weekend we were out, i ran pro tree heads up racing. (two passes anyway before valvetrain let go.) Anyways, i went -.011, then added .015 to the delay box (yes i had delay in it on a pro tree) and went .007 on the green side. I know dragsters and door cars react totally different. From what i've seen, i wouldn't be worried on trans brake releases and all that. Look at all the super gas guys, they run pro tree with majority on electric brakes cuttin hell good lights.
As for the B&J tranny's. From what i hear they're a good piece. Lots of pro mod guys use em. We've never ran em to get a good perspective on them.
If you get a lencodrive and a good convertor (stay away from neil chance, jus my opinion), you'll never need spare parts. We opened ours up jus to check stuff out and it looks like new inside yet. We dont even run a cooler on it. I recommend a cooler, it started gettn pretty warm after some back to back runs at eddyville since we were running both quick 16 and super pro at a few races. I think most guys to testify on my finish line driving habits with this car too. I drove the damn thing like a super comp car pedaling the stripe. (retarded i know, jus habit from other cars i guess). Anyways what i'm gettn at is if'll live through what i put it through, its gotta be a great piece. We had no parts what so ever for it. Hell we didnt even change the fluid in it til we tore it apart for inspection.
Thats jus my 2 cents. if its worth that haha. Hope it helped out in some way.
