Ill have to track down a 6mt quite soon then.

Very interested in the results of cryo-treating. Been trying like hell to find abuse stories about Honda Goldwing rear ends, but all I can find is they never have failures even when towing long miles, but that 800 lbs. bike with a trailer is still much less abuse than my 3-wheeler would dish out and I'd like to get an idea if cryo-treating would do enough to allow me to sleep well at night.

The tranny I just put in tuesday is fully cryo'd, but its not mine. I built it for a friend's 700HP impreza. I'm just "testing" it until his motor is done. And cuz i need to get it on the dyno in 2 weeks.

Cryo treating should be the answer.

Rigoli's are running low 8's launching from the transbrake with a 1000 plus HP with slicks and not blowing them up. This tranny is the same as a rigoli but without the rear drive bias conversion.

My tranny is not cryo'd yet. it also doesn't have a full manual reverse pattern transbrake valvebody. I still use the TCU.

Also if anyone has a 3.90:1 ring and pinion for a Phase 1 4eat to donate or sell let me know

well this is neat. I should venture out of suspension and brakes every once in awhile.

You called me out on nasioc, lol. I like it. When we have actual dyno results, a new thread will be born.



F*** all the naysayers. Honeywell knows what they are doing. The fact that people said that the exhaust housing would melt is hilarious. It takes at least 2100 degrees at just over 2% carbon to melt cast iron. 2800 degrees at anything normal under 2% carbon. And I'm being very rough.

Anyone who said a diesel turbo couldn't handle the heat doesn't know anything about diesels or much about engines at all. Knowing how a diesel works, hearing somewhere, anywhere, about how lean they run (never mind HOW they work in the first place) should knock some brain cells together to point of them realizing diesels have higher exhaust temps than gas. If they don't know that, they know nothing, so why say anything? What's that about a fool opening his mouth? The concern I could see someone mentioning would be possible slower spooling due to reduced exhaust energy and heat on a gas engine and diesels traditionally being large engines, but technology is changing.

Yeah, I know diesels are high compression, I don't know how high, but compression makes things run hotter. Right? How much compression does it take to make a diesel work?

Yeah, its not an instant spool by any means. It basically acts like my GT2871R did, but with much more headroom. A boost threshold of 2500 rpm is pretty decent for such a large unit on a 2.2. Nothing like the off-idle response it has on the 6.0L though.

Me and Dan(93forestpearl) did a little tuning yesterday and made a Video of a 20Psi launch that didn't break the tranny.

http://www.youtube.com/watch?v=y4lDkm6Xj5g Turn up the sound it sounds like a jet taking off

I might hook the transbrake up this week and see if i can break an axel or something.

My wheels look funny on that thing.

wow thats awesome do a vid from inside the car too !

That's crazy.....does sound like a jet!

You should hear my straight piped 6.0!

That thing is nasty. So would you honestly say the auto when built properly can handle 30psi on your setup? Transbrake?

^ It's coming down to whether or not the transfer clutch can launch without slipping. If you notice in the vid the front wheels spin about one rotation before it goes. That tranny has an extra disk in the transfer clutch for a total of seven, verses six in the SS auto and five in the N/A auto. The rest of the tranny will hold it no problem especially with the full manual valve body and the extra line pressure associated with it, among other things.

BMS ended up creating a shaft and other parts to turn it into AWD or RWD with the flip of a switch. No chance for AWD slippage with their setup. It's $2500 worth of parts though

Nice launch vids. Do you have anything to measure how many G's of acceleration that is?

Ive been thinking about a powerglide in my touring wagon. This makes me more interested in doing it.

This tranny, as built will hold a 1000HP it is a essentially the exact same thing rigoli's use without the switchable rwd/awd conversion.

Yes transbrake. This valve body is a full manual reverse shift pattern (PRN1234) with a transbrake. There is just 2 wires going to it. One for transbrake and one for the duty c sol. for AWD.

Here are some vids of the Tony Rigoli Performance WRX

Also if some of you are interested I did snap a few pics when i built this transmission.

I've got the same impact gun I have a thread asking about the clutch pack replacement on a 4eat. Looks like you would have the info I need I'll be looking through you're pics now...

wow.....

So if you dont mind me asking, how much is invested in the transmission to hold this power? Did you replace the flexplate with a stronger one?

I just finished taking out all the auto wiring in my wagon so if i go this route ill need it to be manual shift body, and i can wire in a wire for the duty c lol.

some people have made their own shifters for electronic 4sp autos like the jeep AW4. basically all the gears are selectable by giving power to or not giving power to certain shift solenoids. they put a switch on the TC lockup solenoid as well for more control over compression braking and such. and even incorporated a switch to give the TCU control over the transmission again for just cruising around.
seems like that sort of thing would be straightforward to build for a 4eat if you could figure out the signals the TCU sends the trans to shift. I'm not sure how a setup like that would compare to a full manual VB in terms of shifting performance, reliability and usability.

That is amazing. Awesome launch. Nice quality videos too I was impressed. You should get a wideangle lens for inside the car.

Yeah this thing launches pretty hard. The car the tranny was built for has more power and is lighter (2-door GC impreza). Im just Testing/borrowing it until his motor is built.

As for the cost of this tranny, just parts is about $3700 plus a torque converter and a rebuildable core, and labor.

Keep in mind this tranny is not meant to be used as a daily driver. The off boost shifts are extremely harsh there is no engine breaking in 1st,2nd,3rd gear and no converter clutch. It is meant for street/drag racing only.

Im running a brand new stock wrx flexplate and a rebuilt stock stall wrx converter as they're a little more durable that the phase 1 converters.

As far as comparing a manual valvebody to a manually actuated electronic valvebody. There is none. The manual VB is designed for maximum line pressure at all times. When i say maximum i mean more than even my Trans-go Reprogramming kitted stocker can dream of. All of the shift control orifices are like a quarter inch in diameter. The manual VB shifts are very very quick even at full load. but it comes at a cost of a around $1600.

That said I do not want a full manual VB in my own car although it is very neat to play with for a while, but it does get old. I like to just put it in drive sometimes and let the computer do the rest.


My camera does not accept lenses at all. It's just a Canon Powershot SD780 IS

I will try and get the transbrake hooked up and get a video of a transbrake launch. Or at least a vid of it breaking an axel
