Chump Car racer

Hey Todd,

Still playing with it.
When do you plan to be in the area?
I can get off my butt and speed it up.

Cheers
Fred

[Todd McCreary]

I can't actually dispatch for Chilliwack or Terrace right now.  We have too many high priority loads in front of them.

Probably ( if I get it ) I can dispatch to you in a week or two.

[DiDueColpi]

No prob.
Thanks Todd.

[Todd McCreary]

Oh, it's an open bed 1 ton.  So we'll probably want to have the trans double or triple bagged with Hefties and duct tape for weather.  An old tire would work well for cushioning/mounting.

I've got straps and bungees.

You guys are great!

Fred, could you check your private messages?

This weekend Steve, Dan, and Dave (B) came by to work on the Chump car. We started with a junkyard run to the local pick-n-pull where we rolled an S10 up on it's side and took the starter, bellhousing, flywheel, clutch, pressure plate, clutch fork, throwout bearing, bellhousing dust cover, and center fitting for the oil filter mount. Which cost us all of about $65. We left the S10 WC T-5 which would have cost us $150 because of the tailshaft and gearing.

Back at the Lab, Dave and Steve finished stripping the car while I put worked on mating the engine and transmission and Dan helped out wherever he was needed while also working on his TR7/Lexus swap, and by the time we finished we had the engine/tranny (4 speed) sitting in the car with a strap holding up the tailshaft and I have a couple of photos to prove it:

Sorry I couldn't be there to help. On the bright side, Piper's baseball team did knock off the only undefeated team left.  

[BlownMGB-V8]

Cool!

[Todd McCreary]

Alright, dispatching for Abbotsford, will probably be there Monday.

Fred, could you check your pm's?

[BlownMGB-V8]

Thursday evening Todd came by with the transmission, I have some photos:







Don't know if the numbers are visible in the shots.
Anyway, I stood it up on end in case any water got in during transit but it didn't look like any drained out.

Thanks again to both Fred and Bob... uh, I mean Todd. That's a wonderful thing you guys did. Maybe we can put your names on the race car or something!  :-)

We can put Fred Bobby on the door as driver.

That needs to be "Freddy Bobby" if you're making a Talladega Nights reference.

Which, come to think of it, might be a good theme for the car.

Just, uh, don't be kissing any French drivers on the mouth.  'Kay?

[BlownMGB-V8]

Maybe we name the car Freddy Bobby.

Jim

[MGBV8]

Oops, sorry. Yeah, that's what I meant. I couldn't actually torture myself to watch the movie.

We're back at working on the car, Steve got here yesterday afternoon. We put it on the lift, pulled the front suspension and swapped in the early crossmember and have been putting all that back together. A couple of interesting points. The inner fenders have to be dimpled up maybe 1/4" above the shocks. The front crossmember bolts have to be swapped out for shorter ones, or as we did, turn them down and cut new threads. The steering pinion gets shortened 1-7/16". Nothing special there but we did find dust in the steering rack, not a nice thing to see. The assembly will eventually have to be replaced.

I think we'll put the new brake pads on and finish that up this morning, then move on to the engine and tranny mounts. We installed my old set of Huffaker -1" front springs so the front end will come down noticeably. There is no front swaybar but Steve has a 7/8" bar at home. I think we will split the rear bar and use it for traction control, and then we'll have to decide how to deal with lowering the rear. Maybe a main leaf with reversed eyes will do the trick. We will also bolt up the T5 before the engine goes back in, and if we manage, we might finish up the bottom welds on the driver's floor.

I'll try to get some photos today.

This weekend we swapped in an early front crossmember, which also involved shortening and rethreading the two rear bolts plus shortening the rack pinion 1-7/16", installed the T5 plus a new S10 slave cylinder, positioned the shifter at the rear shifter hole position which required liberal application of a BFH th the tunnel for bell bolt clearance, made up motor mounts and have the damper maybe 3/4" off the crossmember. Photos below.



There is a bit more work on the mounts but you can see how it will go. The driver's side riser will be boxed, the other left open for a pass through.


With the Huffaker -1" competition springs the front will sit about 2" lower than the stock '74-1/2. Thinking about having the rear springs de-arched and adding a leaf.


Steering shaft splice.


Exhaust port clearance is a little tight here. We are considering cast manifolds.


Jim

[Todd McCreary]

you're planning on taking a stagger tape or gauge, right?

[BlownMGB-V8]

Could  be. If I knew what it was...

Jim

[MGBV8]

Do they really measure tire stagger for a road course car running street tires? I thought it was only used with racing slicks & oval tracks.

[Todd McCreary]

Could be. If I knew what it was...


Stagger is difference in tire dia between the left and right side.  You can use a tailor's tape or US race shops sell special "tire tapes" OR sliding gauges demarcated in ( inches / pi ).

Stagger gauges are pretty hard to mishandle.  Stagger TAPE measurements, on the other hand, should always be done by the same crewman with attention to repeatable procedure.  It's very easy to induce variations in tape measurement.


It would be part of your post-pit tire analysis.  Tire pressures and temps should be taken as soon as possible after the tires come off the car.  Tread wear and stagger could wait a little bit.




I thought it was only used with racing slicks & oval tracks.



That was originally my thought as well.  I've reconsidered though.  In a 24hr race, you might burn tire sets bald.   The delta in wear between L and R could be not inconsiderable by the end of the run.

[BlownMGB-V8]

It's not a bad idea, it'd give us something to do during those long mandatory pit stops.

Jim

[BlownMGB-V8]

Another Pit Stop coming up this weekend. Steve gets here Thursday afternoon, Dan will be here Friday evening. We will be fitting the radiator, finishing up the motor mounts, and perhaps installing the driveshaft and exhaust manifolds among other things. Matt will be here over the weekend and Dave will come over when he is free. Carl, and Scott, if either of you guys can make it that'd be great, and we'll not turn away any others who want to stop by.

As well as working on the racer, we will be trying to get Dan's TR7/1UZ conversion to where it can be fired up and driven if we can by the time he leaves on Tuesday.

My car is driveable but still needs wiring done on the transmission controller and a paddle shifter built. I don't expect to spend any time on that, but if I do get the bottom connectors done by then and I like the way it is acting I may take it down the street a time or two.

Jim

[MGBV8]

Here's a trick I missed that we could do.

[BlownMGB-V8]

That rear suspension has a number of what you might call creative solutions and a good bit of out-of-the-box thinking. I love to see those sort of solutions, innovations in suspension design tend to come slowly. I'm not real sure at this point exactly which solution we will use in lowering the car but it sure is nice to have options.
