Suncoast valve body
Does anyone have any info on the machined valve body that suncoast had at PRI? I saw one picture of it, but no information.
|
Looked like it had it own controller sitting there beside it.
|
It was a whole different concept that uses dump valves and a captured clutch torque converter. Not going to be on the market for a good while.
|
Been doing a lot of research on the REs and their overpriced valvebodies recently. They’ve already had their valvebody with shift valves for every gear available...
|
No, stop ^^
What was showcased at PRI is a completely different concept for anything 47/48 lockup style trans. more along the lines of GM 4L, Allison 1000, fomoco 6R captured clutch style torque converters/valvebodies but instead uses dump valves and suncoast proprietary fairy dust. |
I understand the torque converter is different... what’s so different about the valve body that they already offer for 1200 bucks or whatever plus tuner? You keep on saying “dump valves” like they are something special? A standard shift solenoid that these transmissions already use for lockup and OD ARE a dump valve... is there some terminology that i am missing somewhere? The fairy dust comment made me chuckle though. Lol Do they have a link or something with video posted up somewhere? A picture? Anything?
|
I saw something on their facebook page with a video of a torque converter for a 47/48re but it was a very short video that didn't mention hardly anything....

Transbrake FMVB's are already available and have been available from one vendor or another for several years. The biggest advantage to the Cope VB is it allows OD to be commanded with a shifter rather than a toggle switch. And it's built on a simplified "billet" body to eliminate some of the factory casting problems. The new OD command with the manual valve works well for guys using shift noids or racers that want to bang the shifter for all shifts including overdrive.
I believe the main concept for the new billet SunCoast VB is to create a race-specific VB that is super reliable, and addresses some of the current issues the big power racers are facing: torque converter control during spoolup, weird pressure drop issues, inconsistent performance as fluid temp/VB temp changes, etc. The real problem with current FMVB setups using a factory casting is there are over 300 individual parts and pieces in a factory VB with numerous places for fluid bleeds, cross over, sticking valves, etc. With that many moving parts, it's amazing they work as well as they do. Most of the other drag racing specific transmissions have "race-only" simplified "billet" VB's with the minimum amount of moving parts, it's time for the A618 (47re/48re) to get it's own billet VB. |

How many people actually have a t brake that won't wreck an intermediate shaft shortly after letting go of the button. Serious question because I don't see them at any ODSS race |

The fit issues are fixed.

This from a customer in Indy
"That is the most consistent pressure on a transmission I have ever seen" |

What other vendor's besides cope and suncoast? |
there is no other vb like mine on the market anywhere. all gears on the shifter
P NR 1 2 3 4 with automatic or manual lock up. No TCM. No kick down. No governor senors & solenoids. NO delay going into overdrive that you get with shift solenoids. The trans brake solenoid is from a Power Glide used in racing for over 30 years, you can buy or find anywhere. if failed, you dont have to buy my trans brake solenoid cause it is a universal Power Glide solenoid. My VB has the most consistent pressure bar non. The VB may be new, but I am not. 25 years in Chrysler racing, the 48RE VB stems for out from out CRT 727 & CRT 904 VB that has set NHRA national world record in Factory Super Stock G Any questions feel free to call my shop 219-374-0100 John Cope Cope Racing |
Game changer..

Every tb vb out there has issues right now. We put a lot of time into making the goerend vb work, but pressure drops are still excessive at lockup and 1-2 shift. I am in close contact with people that have cope and suncoast as well. We are working together to come up with the best setup, but there isn’t a clear winner at this point. Dump valves will be needed, and suncoast Seems to be the only company that is working on that. |

I know copes first few vbs were 727 based. Since figuring out a few issues its moved over to 618s. Any chance the folks your in contact with using the 727? |

Back up a little bit, cope has been building mopar trans for decades. He released the from scratch full manual transbrake vb a couple years ago for 727(gas) and has a bunch of them out. Towards the end of 2017 he offered that same from scratch full manual transbrake VB for the 618 (diesel) |

We made some changes to JP's Goerend vb and it helped with some issues and it works however it is not perfect.

This is pretty much the only reason I havnt pulled the trigger on one. I have not seen any that work without problems. I want to see one actually go rounds. I went 65+ passes on my Trans last year. I don't want to deal with rebuilds between rounds ect. I would love to test them but for the initial price that's a huge investment. |
