I may bolt in the 5-speed and head down.... we'll see.You got a clutch that will hold it?? BTW, Chris in Bismark is buying a Carbon \ Carbon - borrow it quickly with my tranny and make a few pulls.
$3k for lockup is ridiculous.
Timeslips are better than dyno graphs
Fvckin machine took my quarter

I'm not sure what the clutch will hold... it's a 6-puck ceramic. Prob about 591rwhp is where it would die.
I took the auto trans out tonite... step 1.:DDaveH

I was just talking to the owner of BoostLogic this morning. He dyno'd almost identical to me with a 71mm turbo (my turbo is 72mm). He made ~570rwhp on boost. He had a lockup converter and with the converter locked up he made 730rwhp! I knew there is a lot of loss through a high stall converter, but that seems just crazy.Ive seen it before, not quite those drastic of #'s but pretty far out there. it's not that your loosing hp. It's that the higher the stall, the more slippage at higher rpm's.
O.K., it's loosing hp no matter how you look at it.

Consistency!!!! Alot less chance of missing a shift and possibly destroying an engine. Those 2 would be my first guesses.
I gonna go with that he wouldn't be nearly as quick. The quickest 6 speed Supra is 9.6 something, and that is with over 1000HP. Also, it was difficult to get clutches to hold the power. -
Ethan is mostly right, it's really tough to get a clutch that will launch a (relatively) high HP car at the track. You can drop $4k on a tilton carbon/carbon but I think I'll pass on that. Plus with the auto, you can use a transbrake and build all the boost you want off the line. And finally, with a big turbo there is lag after you shift a manual trans... with the auto you just hold it to the floor and move the shifter.... keeps full HP going the whole pass.

After reading this I think I need to do the lockup mod on my TC (mine requires $25 in parts to accomplish lockup.....glad I don't own a supra.....did I just say that??!?!?!)

Dave is your 3rd gen running?

I had lockup on the built Toyota tranny that I had, but the clutches weren't strong enough and wouldn't hold at WOT. To get lockup on a Glide is serious coin.
I messed up 2 pistons on the MKIII a couple years ago (accidental 30+ psi). I got parts, I just need to put it back together again. I'll have supra number 3 here in a couple weeks.

what year supra are you getting now and is it turboed? -
Dave, have i ever mentioned that if you decide you have too many supras and feel like making a charitable contribution to a worthy cause, my favorite organization is the Chuck Wants A Supra From Dave Foundation?
