mentioned in another thread, has got me wondering...what are these things? Beefed up GM automatics? Are they streetable?
A friend of mine, Ivan at AMS/ Turbo240.comSean, have you ever used a prepped auto on a jap turbo engine? Im thinking of doing this with Nissan SR20DET and would be grateful for any ideas at the moment. Was wondering if a C4 box would be ok with 10 or 9 inch converter. The car will have around 500hp(fly) and idelly used on the road with some drag work.
Got to agree with that Sean, plenty of super gas (9.90) cars using autos all season without any trouble.A friend of mine, Ivan at AMS/ Turbo240.com
runs a C4 behind his KA turbo 240. He has also ran a 300ZX TT auto tranny behind it. Its gone 9.22 @ 156 mph.

The thing with autos is getting the converter right. Too loose is lots of heat. Too tight and it wont come up on boost without a big shot of spray.
An auto is much more consistant. I can't see the point in running a sequential in a 10 or 9 second car.
Last I checked, they only gave the prize money to the guy that wins, not to the guy that shifted it 5 or 6 times.It takes a good driver to manualy change gear 5 / 6 times on a 1/4 mile run:bowdown1:
what skill do you need to push a button to work a airshifter
or even worse just having to keep your foot on the floor with a auto box
700R4 is weak. I know. I have broken about 7 of them behind my Syclone and Typhoons. My Syclone has a broken trans in it right now.Ive seen 2 speed powerglides behind 1000hp 2JZs.
Hell anything is possible if you have the time and money. Put a feckin TH700-r4 behind your RB if you want.
There are companies that will build you an adaptor to your spec.
Wouldnt mind a deal like that :chuckle: Have you got a contact for boxes?C4 Autos only weigh about 75lbs, so they are not that heavy, and can support over a 1000hp if built correctly. For drag racing, autos are the way to go. The one I have will support 1000hp, and it cost me £300 for everything.
