Cafiax

whats the highest a 7AT has gotten with this kit? how does the transmission/torque converter handle the new load? O.o any incidents involving blown transmissions for a 7AT yet with this supercharger kit?

It seems that at this point, the 7ATs start to fail once power levels reach the 500rwhp mark. No word yet on the effectiveness of the upgrades yet, once there are more upgraded 7ATs, we will be able to see how much power it can truly handle.

Out of curiosity, what information do you have to substantiate that 500whp is the limit? At this point, nobody really knows. So far there doesn't seem to be an exact number this transmission breaks at. There are a lot of factors that have a direct impact on an AT surviving forced induction.

I'm not ignoring Cafiax's post, just been extremely busy and I want to come back with a good detailed answer to address his question. Our 7AT upgrade press release is right around the corner and we'll address this in our press release.

It is based off of observations. Shumby and Andrew, those are my main reference points. I stated 500whp as the point where I would not feel that long term durability has been shown to be possible, based off of a few examples.

Since there has been no information released about the valve body upgrades and transmission PCM changes, I was trying to answer the poster's question to the best of my abilities.

Hey Sam

Any updates on the press release for both the 7AT upgrades and the radiator?
