Tom, be sure to cycle the axle through full ride and roll W/O the springs to make sure things clear and no rubs. smileys with beer

Thanks Dave will do

We did that 2 or 3 times over the weekend when we first placed the axle on the A frame and upper links but will definitly be checking everything over many more times before its all bolted up smiling smiley

Tom, exciting that you have now reached this stage. I am hauling the B out to Dave's this weekend --1100 miles each way---and will leave it with him for the week while my wife and some friends and I ski. He will install his vintage spec suspension, some of Peter's C's excellent race shocks, and a hybrid rear end, and then set it all up.

If he lets me, I will post some pictures of Dave and his workplace. Thought you and others might like to see this, if he is OK with that. I have the same curiosity about Hap and his environs---wanting to connect a face and physical space and add another dimension to all these, these words .

Tom,

The MSA blue book has a few updates for 2012 around body/chassis that you may not be aware of. Paragraph 5.2.1 section J. How I read this is that you must enclose all suspension parts from the drivers compartment. So you need some sort of box around the suspension parts.

James thanks for mentioning but all suspension parts front and rear will be separate from the drivers compartment. We are just not using load bearing shock towers.

There will be pics later winking smiley

Sorry about the slow reply to your last post, I would imagine the engine will be actually with us within the next 1 to 2 months. As for set up we are just having a think about that actually, I will be having a chat with Peter to see if hes keen on chassis dynoing the car/engine, I want to check first because the engine will be running Daves crank fired ignition, dry sump ect

I will try an make the April race meet, but it'll be watching only! Will you be going?

Tom,
Yes I'll be at the Donnington meeting competing in the Peter Best Championship for 2012.
I missed the class championship by 1 point last year so hoping to do better this time round.

If your there look out for my car and come and say hi.

If your feeling like a weekend of racing you could always travel from Donington on the Sunday to Castle Combe on the Bank Holiday Monday. I'm entered in the HRDC MGB50 race.

Good luck at Donington James. I can't make it because of the Combe race the next day.

Thanks Joe.

Enjoy Combe. Hope your FIA car goes well. Such a shame we didn't get there this year. Your home track so you should do well.

James

Don,

That sounds really great i would have loved to send the car to Dave to get him to check everything over but may have been a little pricey!

Your going to end up with a pretty awesome car there, please also post/send some pics of your car too

Your engine or at least parts of it are from Dave aren't they? if so i would be keen on sharing any dyno/setup info or how different parts I'm running and your not or the reverse perform. It might be of benefit to both of us if your keen that is?

Tom

Tom, I have Dave's full head, cam, exhaust header and an Oselli intake manifold and Weber 45 massaged by him. Ken Bauerle in Chicago did the assembly and dyno work, and will shortly install the Quaife Rocket Box which is coming from England.

The car will exceed the driver but with effort and focus I hope to narrow the gap.

You have a hotter cam, 0.7 more compression, more engine volume, and of course SUs. You are closer to SCCA spec and I to vintage.

Our differences may be too great for much data-sharing, which now would probably be centered on the induction system (I have a 48 in addition to the 45, and will plug-and-play) and advance issues.

Our engines are cousins, not identical twins; but what a fine extended-family DNA.

Don

Yea I'm sure your right Don I wasn't sure of the exact spec of your engine.

I'm looking forward to comparing the HIF6s and 48 weber on the dyno.

An its certainly quite a family if you include our cars too!

I have a minor correction to Don's last post. His DCOE manifold is all FAB-TEK, long runner casting from TWM(now discontinued) and all contouring/machining done in my shop. His was made from the very last of the about to be scrapped(by TWM) castings that I bought several years ago because I really liked the design.

I have accumulated a diverse collection of DCOE manifolds. The least favorable one (IMO) is the short runner TWM although this one fits on an MGA I am Told.

The ones I like most from a design perspective are the Oselli, Pierce, and Warneford(sp?)which may no longer be made. If Someone knows otherwise, please let me know. The Pierce is the longest but I'm not sure about vehicle fit.

Dave,

If you click on the link below you will see the MGB (right hand drive only) manifold that is readily available from Moss. How does this compare to the old TWM design?

Joe, from the picture and dimensions that looks good. I suspect that RH drive only is because of the linkage or power brake interference which is not an issue with a race car. smileys with beer
