Its not in the car yet but I have been in one built by protrans & it was awesome. It was perfectly mannered on the street, shifted smooth & crisp & no lag. With the right combo they can be every bit as streetable as the zf without the worry of software issues, slipped clutches & broken input shafts for me that makes them every bit streetable as the zf. We're gonna play with diff gear options to see what we need at the track but it'll either be 2.73's or 3.23's.If the issue continues give me a yell, by then I should of had the box in the car & I can tell ya exactly how it is. 1 Link to comment Share on other sites More sharing options...

Give ALI a call he knows those boxes inside out and could possibly shed light on the issue Link to comment Share on other sites More sharing options...

It's easy to make that on the dyno & take it on the street due to wheelspin taking alot ot the stress away but has solid testing & durability tests really been done. Its all good to say it'll do it but to test & prove is another thing??? 1 Link to comment Share on other sites More sharing options...

Launching 1.5 60 fts and still going for more.Two 9 sec passes also.What's BTA done, put up a video of him driving down a street and pushes himself into the seat to make it look like his punching it ,so it doesnt go into limpmode. 1 Link to comment Share on other sites More sharing options...
