    For us around here this is the strip. Lol. Been wanting to make it to real strip to see what I can get it to do but can't get off work to go then having some issues with the ucon. The gauges don't wanna display and data logs don't wanna function while Luanch control is active and the ucon kills the power because it runs to lean Idk what's wrong. I Think it is a software issue myself. When I transfer the utune program over to a different pc it started doing stupid crap. So idk hopefully it can be a quick fix. It's prolly because I like to party and run the biggest blower with the smallest pulley. Lol

    Well I must be to much for the -92 blower. Had to put my old -81 back on. The -92 was blowing fluid out of the oil tank under boost and throwing it out the compresser outlet. Output shaft seal must be out.

    So you've been burning rotrex traction fluid in your engine? :oops:

    Man that doesn't sound. I hope you can get the unit replaced under warranty.

    Yeap burning a small amount of it, most of the fluid was blowing out the vent cap tho. Yea I'm hoping I can to, I already miss the -92. While it was out I measured the compressor wheel. 70mm inducer and 105mm exducer.

    Didn't buy the -92 from urd. Gadget can't help me with warranty claims. I'm in contact with the ppl I bought from so hopefully I get a new unit and it don't cost me a arm and a leg again.

    Update no warranty will be made on -92 . Said I was at fault so sent it to have it rebuilt. And now It seems I’ve tore another center section out of a clutch again. Fml

    Man, how do you manage to do those things to your truck?

    They can, but Rotrex doesn't recommend it. I've seen rebuild parts for the -81, but never seen someone selling -91/92 parts.

    all c38 units have same drive sections seals bearings and what not. I have output shaft seal out. Guy in Texas rebuilds them and sells parts for them. 250$ To get it fixed. And the clutch idk, the last one did the same thing but lasted a few years. This one didn’t make it long at all. Stage 3+ isn’t made for drag racing is all I can say. Going with solid hub this time around.

    I use urd clutch’s. After the last one broke it got sent back to see what caused it and they said the alignment of the trans, no pilot bearing and input shaft having slack and me ramming and jamming on it cause flexing while the clutch spun out of center and it rips the center out after some much of it. Comes down to these shitty transmission. I’m getting gadget to make me a solid hub disk. I’m gonna try that see how it holds up. Maybe something else wil break this time. I’ve got plans for a t56 swap when the trans breaks.

    Just curious but what did they say you did to cause the failure?

    But yeah. These are by far the shittiest transmissions ever put in any vehicle lol.

    Said that because this trans doesn’t have a pilot shaft and bearing no support for input shaft will cause the clutch to clamp and spin out of center causing lots is of flex and The misalignment of then trans to the engine. Lazy cheap toyota design leads to flexing and making the metal weak over time Not so bad under normal power but put 450hp plus and some drag tires and the problems become worse a lot faster T56 swap will cure this problem tho. For the most part anyways Lol. I’m the only person to break the urd clutch tho.
