New times with BR clutchless 4 speed
the flexplate is what holds the torque converter to the crank. on some vehicles flexplates have ring gears attached so they do indeed look like a thin flywheel. the mitsu stuff however has the ring gear mounted on the torque converter.
That has to be one of the coolest pulls I've ever seen.
I'd imagine at some point I'll dyno the car, I have had no interest to date because so far it was a struggle to get it all to work and any time I can put on the trans I want to put on it attempting to drive it or make passes, not waste them on the dyno. From the very first pull I made the tune has been 100% spot on from when it was a 5 speed, so there was no tuning needed, no need for the dyno. I know it makes less power to the wheels, it's impossible for it to not have lost WHP, I don't particularly want to see some low number, actually I don't want to see a low number at all. So my attitude will stay better by busting some ET *** at the track and knowing what I am doing is making the car more consistent, reliable and quicker.
I may throw it on the dyno once it runs the ET I want to see it run to do a comparison of some sort of what kind of power it had when it ran 9.04 on the 5 speed and what it has if and when it goes into the 8's.
When my car ran 9.0 at 159 it only made about 684 whp on our dyno. Since then we've had a bunch of combination in the car that have made the same or more and have been back into the 9.1'-9.2's many-many times and have also run 158-159 trap speeds but have never run 9.0's again since and that 9.0 run was in 2008! So to see the car dropping back down and doing it so effortlessly so quickly on this trans is very encouraging to me, although watching it is a bit boring now because it's so damn smooth! haha
I spoke with Kiggly tonight and he is going to get right on making the new flexplate we need, I hope to be back out next week, maybe Friday night at D42.
BTW and I could be totally wrong on this, I think there is another good tenth in this next change we are going to make to the trans. While it's holding the power perfectly (from all we can tell) we are pretty sure there is time being lost in the shifts. Based on how "poorly" it shifts off boost and out of power we are hoping this next change is going to speed the shifts and pick up some ET and MPH. Right now out of boost the car on the shifts feels like it is almost in two gears at once, hard to explain, very mushy shifts and not crisp/firm at all. The first trans we were using that simply is not going to hold up, was real firm but we had changed some other things in it. That is the next step with this one and we are going to do it while it's out. The shifts at WOT seem good but it's not actually possible for the low side to poor and higher side to be good, this change is needed it seems and should give us a little more.
wow that is amazingly smooth. it really does look like it will eliminate the stress on the drivetrain altogether, could pay for itself for those out there driving hard enough to break stuff.
Just for an update. We are simply waiting right now on Kiggly to make some custom flexplates for us. I was going to half *** the car together again to make some runs but don't want to do it. I'd like to get it together so we can actually run it and make some passes and prove it's going to hold up or address whatever is next to break, fixing the same thing over and over from short cutting it is stupid though.
So if all goes well next week we will run again.
