I went to Silver Dollar yesterday to test out my setup before heading up to MIR this week. The first couple motor runs were clean runs, and as usual my 60's suffered due to no track prep, and spinning out the hole:




Nitrous Dyno numbers were 597rwhp/800rwtq on the Dynamics Dyno. As a reference I dynode 360rwhp/415rwtq bone stock. The green numbers were motor runs:



First Nitrous pass

I was a little concerned with the amount of TQ the gas made, and after 5 dyno runs and on my first track pass, the stock trans let go. You can hear in the vid right after it shifted into second, the motor becomes disconnected from the trans, and that was all she wrote. The trans was stuck in second with cels reading "trans slipping."



I will look into mating a V12 Twin Turbo trans to my E55 motor. In the meantime, I have a spare e55 trans that I hope to install this week, so I can still make MIR.

***** out. That's a monster. Damn Craig!
Tranny out no big deal..

i bet it felt good before that.

Now that's a way to take out a trans!

Do not waste your money on the v12 trans. They just have larger gear sets in them really no more clutches. Just build a standard transmission. Tighten up the clearances and add a few clutches to the packs. It is pretty easy to add a one or two cluthes to most clutch packs. Getting the clearances tight is the most important. When you start making a lot of power you can blow through a shift pretty fast causing limp mode. Also you may have hit a torque limiter if it went into neutral.

Yes it went in limp mode when that happened. I will know more tomorrow when I take a look at it.

Nice numbers and tranny death

Was that the original trans? If so how many miles did it last?

damn Craig, see this is why I let you chase the numbers. And you better get that thing ready for MIR. We need both cars up there!!

blackbenzz

Wow your car is moving even without the spray. Can only imagine what it will do on spray and traction. What was your 60' on spray?

chawkins2001

Yes, that was the original trans and it had 56k miles on it.

My 60 ft was 1.85 on that run brotha.

I thought I saw some activity at the shop during a drive by.

I was going to bring mine in on Friday...but my o2's seem fine after a clear. Weird.

chawkins2001

Yes, there was activity and I just saw you a little bit ago in the beast

The trans is done as it is slipping under normal driving conditions now.

TheOtherDodge

Nice motor runs! Can't wait to see it once back together!

chawkins2001

Thx brotha, appreciate it. I am just going to rebuild the stock tranny with A LOT more clutches than stock with tighter clearances. No sense in turning back now.

WHTEVO

I think you can upgrade the clutches to the ones from the V12 trans which are beefier if i recall. Good luck man!

SterlingE55

Haha. Just watched the video. "WHY'D HE LET OFF!!!".....

chawkins2001

After I watched it, I said I told Jason and Mike I did not let off homes, it slipped like a **** and popped

ArmoE55

Are you running open headers? That car is LOUD.

Hope you get the car squared away soon ...

This car deserves better, and HD cameras are dirt cheap these days.

That vid was with the new I Phone, so I am not sure why it turned out like it had a potatoe lens

ArmoE55, I always run with my cutouts open, so that is open headers on my setup.

BI-Performance

The tear down of a 20K mile good tranny begins, we had a spare at the shop from a donor e55 that was salvaged. We will be building it with much tighter clearances, and stuffing in as many clutch packs as possible.

Building it this way will have harder firmer shifts with less ability to slip under heavy torque loads. After testing it with a few bottles, we will offer the next one for sale:

looking foward to the results
