I did a little editing (thx for vid wannabe)

[Joel]

you and your fancy video editing

[My NOva]

what program did u use therejim??? and does he have a vid of it with nos???

[Joel]

He didn't run n2o that I'm aware of. It's fricken hilarious. A under 600 pony supra is running faster times than supra's upwards of 900 horse. Way to go Dave!

Cool. I did the swap in that civic hatch. Nice to see that he got a decently strong motor at least.

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.

I don't doubt that dave- the converters soak up soooo much power- alot of good race powerglides only take 20-30 HP to turn (which is minute) and I find alot of drag race guys that put 900 on the engine dyno only turn 550-650 on the chassis dyno. Time for 5 speed dyno time again???

I was saying to Stephen and TJamz that your turbo should be making 700+ rwhp. I was trying to figure out if the timing was conservative, the boost real low, or I had my numbers backwards.

Makes more sense now. Can you lock your converter up????

[DaveH]

That lockup stuff is like $3000... too expensive for my cheap azz.

Andy, don't forget to add me to the dyno top ten now! 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

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.:D

I was always wondering why you run with auto instead of manual. (dave h)

[weshole]

Consistency!!!! Alot less chance of missing a shift and possibly destroying an engine. Those 2 would be my first guesses.

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.

Thats what i was thinking, just wanted second opinion.

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.

[DaveH]

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.

[92TSIpos]

Lets all switch to auto
