Re: Radiator plumbing

Hi Steve,
Thanks for the confirmation. I assumed this would work but I've thought that before on other things only to be bitten.

Radiator plumbing

I've got a 72 degree TC water outlet on the way to replace my seriously corroded outlet. As I understand it these were aluminum for TB/TC but my old outlet is very magnetic. Odd. Anyway, on to my question. I was looking at my newer SS thermostat housing and was wondering if I couldn't just drill a 2...

Re: Moss supercharger question

Hi Ray, I just read your write-up - nicely done! My arrangement was different in that I had the extractor plumbed to the oil catch can and from there to an adjustable PCV device installed in the road tube. Before trying the extractor I had the catch can running to a center tap on the intake manifold...

Re: Moss supercharger question

Hi Ray, Thanks for the info. I have tried twice to use an exhaust extractor with no luck. The unit I tried is: https://antisplataero.com/products/crankcase-vacuum-kit-complete but I think they are all the same. I can't determine whether it's the small diameter of the TC exhaust, the flex section or ...

Moss supercharger question

I'm about to throw in the towel on my Shorrock supercharger install. I'm convinced that there is a fundamental internal issue that I don't feel like dealing with at this time. With my mostly non-functional Moss rear seal I've got to run a PCV system in any hope of keeping oil in the engine. So, my q...

Re: Supercharger Carburation Issue

Thanks Duncan, I've seen that writeup before and it's pretty close to what I have. Problem is that it won't run long enough to do any investigation. Turns over on the starter then catches and runs for a few seconds then quits all the while coughing and sometimes sneezing through the carb. When it st...

Supercharger Carburation Issue

I'm having a fuel issue with my newly installed Shorrock supercharger on my TC. Everything is mounted and plumbed but it will not run well or at all, just spitting and coughing. It appears to be flooding as there is raw fuel dripping out of the intake side of the carb. It's a single H4 with a side d...

Re: TC choke cable length

Thank you Steve. That is helpful. I haven't removed the cable from my car yet as I have a kluged mount that mostly works. At least enough to try to fire it up in a few days. Here is a picture showing the choke kludge and how short the cable is with the lever on the bonnet side. https://drive.google....

TC choke cable length

If anyone has a TC choke cable out of the car would you let me know the length of the shield? The cable in the car now is too short to work with my Shorrock supercharger setup. If I mount the choke linkage with the lever on the engine side the lever fouls on the throttle rod. Mounted on the bonnet s...

Re: Electric puller fan on a TC

Duncan, I would mount the fan on the back side of the radiator between it and the snout of the water pump pulley.
This is a puller configuration which is supposed to be more efficient that pushing from the front. The biggest downside to this
is breaking down the radiator shell to mount the fan.

Re: Electric puller fan on a TC

Thanks for the info guys. I had not thought of doing a pusher on the TC. Since a puller is supposed to be more efficient I had only thought of going that way. I did find a fan that should fit. It's a Davies-Craig #0147, 10" slimline reversable pusher/puller. The interesting part is that it's only 55...

Electric puller fan on a TC

Has anyone installed an electric puller fan on their TC? If you have would you share what model (Hayden) and size fan you used? Things are getting ridiculously close between the supercharger drive belts, cooling fan and the radiator. Maybe it's time to ditch the engine driven fan. Thanks, Dave '46 T...

Re: MG-TC and Shorrock supercharger

Anyone know whether a radiator fan spacer was used with the Shorrock? I finally got the new crank pulley installed and noticed that the front supercharger belt will foul the fan blades. I was thinking about getting a TD spacer and cutting it down as required.

Re: MG-TC and Shorrock supercharger

Duncan, I'm not too sure yet. I've been doing some reading about timing under boost but haven't settled on anything. I'll probably keep the MAP sensor disconnected at first. Do you have any suggestions? Steve, Do you recall how your timing is set? Looking at your picture do you have a secondary fuel...

Re: MG-TC and Shorrock supercharger

Thanks for the info guys. I bought a blow off valve relocation kit from the folks in UK and had a local shop tig weld the bung in place. It comes out at a funny angle on the top of the manifold but it's not under and next to the hot exhaust. Earlier I installed a CSI programmable distributor that ha...

MG-TC and Shorrock supercharger

I'm about to start on the installation of a Shorrock blower on my '46 MG-TC. The installation seem fairly
straightforward but I always expect the unexpected. Has anyone here done this install and have any tips, or
gotchas to pass along? I've heard about possible fan clearances.

Thanks,

Re: H2 carb float bowl orientation

Thanks for that info Duncan. I was away for a few days. I did check for any floating difference between the brass and nitrofil floats. Both float the same in a jar of fuel. Both sit somewhat unlevel at 50% below the fuel level. So there should be no difference in performance. While we were away I de...

Re: H2 carb float bowl orientation

Thanks for the info guys. I've just come in from the shop and things are not well here. If I start reducing the diameter of the test rod the fuel level in the jet does rise accordingly. But, to get close to the .220 below the bridge the fork is almost flat and I think the nitrophil float may actuall...

Re: H2 carb float bowl orientation

OK, I'm confused. I found a reference in the NEMGTR tech reference that the arms should be as close to perpendicular to the carb body as possible. I have done that. I've set the float levels using the 7/16 tube in the SU tool kit. When I turn on the fuel pump runs until it stops. When I check the fu...

H2 carb float bowl orientation

Are the arms on the float bowls supposed to be perfectly perpendicular to the carb body? I suspect they should be
but mine are not. I'm guessing this is leading to the difference in fuel level in the jets.
Thought I'd ask before I create some new leaks.

Thanks,

Dave
