MG MGB GT V8 Factory Originals Technical - wilwood clutch slave?

Has anyone used this with a T5 and stock MG master Cyl yet?? Has anyone used it at all?? I am thinking abotu using it to replace my HTOB and use stock mustang clutch assembly...

I am using the Wilwood master cyl with remote reservoir. 0.75" although the slave is I think SD1 on R380 bellhousing. Works fine. The original V8 master measured at 0.75"

I have a hyd clutch setup on my T5 with the 5 L Ford. Dale Spooner improved on the setup I used and wrote it up in the last V8 newsletter. We both used a CNC slave cylinder and he refined by using a Girling 0.700 master cylinder which bolts right into the stock location.
It makes for a good clutch --a bit heavy for some maybe -but I like it.
The article in vol XII No 1 covers the whole thing nicely
All the best --Gil

HRMMM, How much are those CNC units?? mostly just the slave. THe Wilwood unit is a puller type slave, so it could mount to the place where the mustang's cable assembly is held on the bellhousing.

I appreciate that there are numbers on bore sizes too heh that helps quite a bit so I can figure out what I may need to do..

As listed the bore on that unit is .88" which should give great pedal feel. Right now mine is a bit to hard for the wife to manage. I will have to see if I can get some $$ put aside to use that.. Right now I am looing at pulling the motor AGAIN, to try and adjust the HTOB as the openging is to small to get a hand and feeler gauge in when installed to set it properly..

Larry---I used the CNC push slave cylinder part # 305B its about $50.00 from Car Shop Inc.I made my own push rod from a 3/8-24 UNF X 6 in grade 8 bolt --just cut off head and round off end to fit the piston--works fine.
I dont know if there is room for pullertype --I didnt even try.

A buddy at work has a CNC uoll type slave at home from one of his sandrails. I am going to get that and see what I can work up. yes the length of the slave culd be an issue.. heh time will tell.

Larry, I used the Wilwood pull type slave cylinder on my MGC GT with a 5.0L Ford. It fits right into the space between the release arm and where the cable passes through the flange on the bellhousing. Works well with a 7/8" Girling M/C. It is slightly heavy but you may not get enough movement to fully release the clutch using a smaller M/C diameter. Clutch action is progressive and easy to modulate. You can even refit the aluminum cover for the cable system in place over it! Bob.

BOB,
Thanks!!! you HAVE to bring her down to ABFM this year!! I need more 5.0 people to keep the buick guys in check!!!

I hope to use the stock MC, but we will see.

Larry __I tred stock m/c with my set up --it didnt have enough volume or travel to fully operate the slave so I went to a 1 inch --but it is overkill . Seems to me the setup Dale came up with is perfect.
Gil Price

Gil,I've never heard my name and the word perfect in the same sentence.I'm surprised your spell check didn't spot the error.Larry,Gil and I are both happy with Gil's design,but the ability to reuse the original fork cover with Bob's puller setup is intriguing for sure.I haven't come up with a cover yet,have you Gil?Bob,what are you using for a clutch and could this be the reason for your slightly heavy pedal (as I think mine is)? Dale
Dale

Dale--had to be kind --youre trying to leave the area :-).No cover on mine either but havent really persued it.i'll let you know if I get a brainwave!
Gil Price

Larry - I will be at the ABFM so if you are coming up you would be able to see the set-up. I'm using the standard Mustang (10.5"?)clutch with the original 1995 T-5. The Ford release arm set-up, being pivoted on the "far" side of the input shaft has a longer throw and lower pressure needs to suit the cable system. The Wilwood cylinder has about an inch of actual throw - just enough to release the clutch with a bit left over. I think it is a 3/4" bore so I calculated the fluid volume involved and the 7/8" Girling would give me just enough transfer to provide the full 1" and have the slave cylinder fit in the gap between the release arm and the cable flange on the bellhousing. It has worked perfectly to date and actually feels much better thabn a cable system in my opinion. It is retained by a bolt passing through the hole in the flange. Bob.
Bob Elwin

Larry, Another thought - it could be that the Wilwood slave fits my application and maybe not earlier set-ups because the '94 and '95 SN-95 Mustangs have a longer gearbox input shaft (and a longer bellhousing) apparently in order to achieve the correct gearlever placement in the new body. Whether the difference (about 1/2") is reflected in the distance from the release lever to the cable flange; I'm not sure but I could measure it for you.
Dale, the cover is the standard Ford alloy cover for the cable system with two tongues on the front and a bolt screwing into the rear of the bellhousing. The Wrecker or Ford should have them. You just have to make a slot in the side for the hydraulic line. Bob.
Bob Elwin

yes the 94/95 T5's are actually about 3/4" longer in the input shaft, so that would be a longer bellhousing..

It will be a few weeks before I get that CNC model from my buddy, but I will keep everyone informed.

I should be at ABFM, car will not be done by any means, but I will bring her up baring any major unforseen issues..
