Time for a tighter converter Well it seems I have too much converter for nitrous. The car blows through the converter with a 150 shot. I downed it to a 125 shot and went 11.1@121. The converter I have is a Hughes 3500 loosened to 4000. I originally loosened the converter because the car was a dog all motor. 1.8 60fts and the car wouldn't idle in gear well. The cam I'm using is built for nitrous Comp .562/.581 lift 248/258@.050. Next year I'm going to a 408 stroker and I'm going to use the the same cam. What would be a good converter for 250 shot, most likely dual stage?

Its hard to get a converter that performs in both enviroments well. I have heard of some people geting the converter set up well withall motor and then locking it on spray with decent results.But you would need a multi disk converter for that.

Nitrous cams are famous for not making power on motor. I am not surprised at your comments. Hate to see you dealing with trying to make a combo work.
Sometimes it is hard to have the best of both worlds. Indeed that converter is way too much for the N2O. As far as the idle condition with a 3500 stall converter.. I would think that condition could be tuned. But hey, maybe it can't. A 3500 rpm converter is fairly loose to begine with, especially when we are talking about idle quality. A nitrous converter is going to naturally be on the tight side of course, but I would be surprised to see your engine slaving at idle with it.
Good Luck with it.

I have an Art Carr 3600/3800 that is too tight IMO. it is built for 700+rwhp and a 250 shot of nitrous...
It does 1.70 60fts on motor
1.48 60fts on the bottle
It stalls to 3200 on the footbrake. A transbrake is a good cure for a tight converter.
Mine has 600-800 street/track miles on it. I will sell for $450.00! I want to buy a Neil Chance for $1k+........ pm me!
