Well I just got a built C4 from Jay at Broader Performance for my 88LX foxbody. This is the first time I have dealt with him and he seems like a pretty stand up guy. Anyways, my car weighs about 2900lbs with me in it. It has a single turbo on it with a bone stock 5.0 in it. car makes [email protected] and [email protected] car went [email protected] with a DA of over 5000ft. My problem is the trans break goes up to 4k at the line. I think thats a little high. I was thinking a 2500 would be better with my motor setup. Also, it seems I'm getting a lot of converter slip, everytime I shift the car doesn't go below 4500 and it feels like its not moving down the track like it was with the stock converter. But, It still trapped the same with the stock AOD and converter. I thought that was strange. It is also crossing the traps at 6k which is higher than with my stock AOD and I put 28 tall tires on this time. I ran 26s with the AOD. Lastly, the tranny temp goes through the roof just driving around town for 10 min. Like 210. At the track on the T brake it would get to 240 at the end of the track. I talked to Jay at Broader and he is going to build me a 12inch converter that will stall at 2500-3k, so he is taking care of me. So what are all you turbo guys running in your C4's? Should I do this 12inch converter or is there something else I need to get the right stall and the temp down.
