The brake is an aluminum block with passages machined through-out it with a solenoid. I feel it would be fairly easy to duplicate but being professional about it, I choose to purchase them directly from Carl. Anyone interested in the a set up feel free to contact us. To answer a big question before I get flooded with this question, You must remove the transmission and make internal modifications for the transbrake to function. It is not a simple bolt in.
DAMM run a trans brake and a 2 step like dr. phil does on a twin c5.......

rodney will definitely get my biz if anyone is serious about going stick, my car also has a nice textralia clutch. I would love to find someone that can work with me and we can both ride into rodney and switcheroo.
I'm also interested in the aftermarket paddle shifters.
a built slushy, with a brake, and a paddle (also with a decent floor shifter) would be the bomb.
I know I will reduce the rwhp with this mod but the convenience and drag potential of the setup really interests me. I need something that will hold 1k rwhp as I will likely step up to a bit more boost and a stronger engine down the road if that's indeed feasible.
also interested in the new c6 6 spd. it's a bit early for that one as no trick convertors are out, but I'm a patient man.
I'm not talented enough to launch a stick car and don't want to deal with the frequent breakage of "hammering" the drivetrain, and really like the idea of lightly t braking to build boost to get the 60 ft times down without killing the rear.
also looking to go to a 3.42 gear to increase the top end. I have a 3.90 gear in there now. thanks folks! this is really interesting.

sounds like a beefed rear end with a hardened gear set will be needed. My car has the big shafts which hopefully can be reused.
sounds like this will be more around 8k before all is said and done which is OK.
would you folks enlighten me about the 2 step?? is this a 2 stage boost controller that has a launch setting?? I'm not sure what we are talking about as a two step typically is a rpm limiter on a drag car that sets the launch rpm when using the transbrake.
I'm not going to beat my car to death on the drag strip but I certainly will make a few passes to validate the performance
dyno numbers are nice but I like the ET and MPH numbers better!!
the vettes typically 60 ft pretty lousy with the stiff suspension, but these mods sure sound like they will help there.
I haven't been able to do much with a 6 spd, my clutch foot isn't that talented.

I would leave the line with about 4 psi, at 4500 rpm.
thanks for the explanation. it's exactly what I thought, just like the RPM limiter I have on my drag car. cool. is this an MSD box??? the one I have had RPM pills that you used, but if the newer ones could dial up the rpms that would be better.
I've heard all that banging around on the line and it sounds pretty bad but doesn't hurt anything. I hadn't thought about the spark chop spooling but yes, that extra fuel dumping into the manifolds will spool those bad boys nicely.
I know the rally cars even use an injector to dump and ignite raw fuel in the exh to spool coming off corners. that's a bit too much for me!!
the turbo tech is just way cool. thanks for the 411 on the 2 step.

Not a problem. The one that I have is from Harlan (Harlan Engineering). He is not currently making them anymore but it is rumored that they are coming out with another one.. just no timeframe that I am aware of.
Rick has some that they are making too. I have not used one, but the same principles apply.
I will not get into the benefits of combining several of the things here because I am looking forward to whipping the bajesus out of the forum boys the next time we get together...

It is funny, it stays warm here relative to you... our track will actually stay open through January as long as it is over 40. They open on Saturday and/or Sunday afternoons.
Pretty cool.

If someone can post all the part besides the tranny that would be helpful. Even recomended converters etc, this way i can start collecting all the parts over the winter and just get the tranny from Rodney when ready. I would like to do the swap so it looks as factory as possible-is this possible? Does ECS do these swaps?

I'd like to explore the parts list and the transbrake more. it seems like you wouldn't need such a loose conv. with the turbo as "grunting" the turbos would build boost faster.
rodney is the man but you still will need to scrounge up the parts for him to redo them.
let's see
torq tube
4l60e
3.42 diff with hardened gears
PCM tuning and reflash for automatic (any wiring needed??)
driveshaft?
DTE brace?? (is that for manual trannys only, probably??)
convertor (multi disk, precision??)
new console
shifter
what I'm looking to do is figure out the best "shopping list" to start stockpiling so I can drag the whole enchilada for the swap.
if anyone is really serious about this and wants a nice Rodney level 5 6 spd let me know. I'm not in any hurry as I just bought the car but I think overall the performance with the automatic would be better
my textraila clutch holds well but it "barks like a seal" if I let the clutch out quickly. almost sounds like a bad bearing or something. really strange noise. I don't think anything is wrong, but I have been pretty ez on it coming out of the hole as it makes me nervous.
thanks!!
