Thats a lot of motor, the 2.8. what did those cars weigh? and i am probbably going to a solid rear mount. I have the upgraded passenger side in place and tranny side awaiting my install. i did notice the teh passenger mount was nearly destroyed when i recently replaced and i am quite sure my Corksports are gone with the rest of the stock material. I like the spare in the glove box, as if it were a true british car!

I had trouble finding the gates quickly when the car was new... but I replaced the shifter base bushings with steel washers and it helped the shift feel alot. A shifter base is not something that should have been made from plastic.... and that hurts the shift feel on this car alot. I looked at the shift cables and still see nothing about them that would cause missed shifts... usually missed shifts (ones that aren't caused by missing the gate) are caused by the syncro not doing it's job... either because the clutch wasn't down far enough while the shifter was being moved or because the transmission had the wrong fluid in it (or burnt out fluid). I recently tried redline MT90 and Amsoil MTG and both caused a delay in the shifting... they are too slippery. I'm trying out a few different fluids to see what works best and doesn't cause diff noise. I use BG syncroshift or Pennzoil syncromesh in my DSM and those are the only two fluids that make it shift perfectly smooth... and neither are OEM recommended. Once I get more time and money I'm going to order a few bottles of BG and try it in there to see how well it shifts.

My Capri, with V6, weighed ~2300 pounds. The 2.8 V6 had a Holley 390 2V on top and a set of headers and duals. It ripped good, for '70s tech. 3.44 final drive made the car top out at about 200 kph. The 2.8 eventually just tore the car to shreds. One day, booting hard off the line, it torqued the chassis so hard the rad jumped off its mounts and suicided into the engine fan, lol.
Ahh the bad old days.....

Just regular standard 24 hour to full cure epoxy, because that's what I had a tube of lying around. It just needs to be solid, as you say. 5 minute stuff will be fine, too.
An honorable death.

That was only one of many deaths, lol
I used JB weld to clean up the holes in the rad and ran it another year like that.
The main lower control arm had one bolt to secure it to the frame (British design) and that sheared off at speed one day. I managed to bring it to a stop without incident.
I lost brake hydraulic pressure (no safety circuit, factory design) and went through an intersection, spinning and destroying a Toyota Corolla but hardly damaging the Capri. Patched up the leak and drove it home later.
The factory oil pressure gauge was a Bourdon tube, through the firewall and hooked up to the gauge. The fitting failed, spraying the driver's footwell with hot 10W30. That sidelined it for a bit, the insurance lapsed and it got towed. I gave it to the towing company to settle the bill, lol.

P.S. Oh and not only that, the full voltage (such as it was) of the ignition system was routed through the tachometer so, if the tach failed, as it once did, the car wouldn't run (spin)
Kids b**** these days when they get a Mazda, Toyota or a Honda as a first car, with more power than two of the Capri's original 1.6 litre engines, AC, a radio, pw, locks, safety cell, airbags, and the extreme likelihood that nothing will go wrong with the car for at least 5 years.

Yeh but how many kids, or adults even, ever had a Capri. And how many kids even know what one is/was? hah. yep those were different times i suppose. i have tried to get cars for my kids that they would have to work on and maintain themselves, so they would respect their cars. First thing i bought them was a repair manual! It has worked pretty well so far i guess i am old school a little.

I'm just so glad I can work on a car for pleasure now, not because it blew up and left me stranded. These are the good old days....
Mid-day today I ran a little accelerometer test on my favorite area of mostly untravelled and straight, flat road. Wanted to see what 93 degree ambient temp would do.
Wouldn't you know it -- thought I had a decent launch (for me) and then missed the 2-3 shift.
I stayed in the run anyway to see what the data looked like. Now I have nice comparison chart (attached) to show just how bad a missed shift hurts you. We all know what that means at the strip. But looking at the cold hard data makes me sick because I made great power, even in the heat, only to have the run end up being a 13.9 rather than a 13.4 or 13.5 because of the time I lost trying to get the damn tranny into third -- it's there on the data print out just as clear as day.
And I thought I had that 2-3 shift licked. Was getting it right 90% of the time. But 90% ain't 100% So, epoxy glue rear MM fix for me.

I bet you would get a lot of hits if you wrote a How To on epoxying the rear motor mount, I know I would personally like to see how it is done.

OK here it is:
Once you've removed the rear MM, as described multiply, tape off the bottom side of the mount so the epoxy doesn't leak out. Fill the voids in the mount with epoxy, staying clear of the bolt hole. Leave, drink a beer, come back when it's dry, reinstall.

I think i am going to look into the freee shifter mod and maybe further. I have been working on the flat shift technique alot. I have been shifting earlier in the revs but staying on boost. As i might have mentioned the 1-2 are just fine the 3-4 even better. But guess what, i am pulling the 2-3s off. Shifting at about 5000 till i get comfortable with this. I have done it about five times and have not missed. Maybe it has been the driver mod?! all along. It might be time to get back to the track again. Now i think the issue might be at the shifter now since the mounts are taken care of. Thats good cuz i was sure the tranny was in disrepair, and i now have hope again.
Ericrapp, you may be on to something. What I thought worked and seemed to work has me back to missing 2-3 more now. It's only 2-3. I think the stock rear mount has gotten worse over time. Or maybe it's me getting worse after having gotten better!
Maybe the epoxy MM fix will restore my confidence. Maybe part of it is mental: if I worry about missing the shift, then I WILL miss the shift sort of thinking.

Hey thats cool that the oil helped out. i am just understanding, that it can be be a b**** when i keep thinking that i am going to miss third when i go racing. Maybe you have never had the pleasure of messing up when in serious competition. When an adult male misses a shift while under pressure. well what are the women to think? have redline MT90, And motor mounts upgraded.
