The place we ran weight boxes back then was on the floor pan in the steering cavity, that got it low & on the chassis. Lots of room down there & easy to get to with a wheel off. The spare wheel well is in the body, not a good place for weight.

Didn't think of there - agreed - there's definitely a lot of space and it would sit lower too. Was thinking along the lines of furthest forward to bring the C of G nearer to the center of the car. What's more important? C of G lower or in centre of car?

. Mid race one time it picked up 500rpm after someone had tapped me in the arse, it turned out the engine hatch was sticking straight out. We closed the door & lost the 500rpm. So from that we decided to build a tail,


just curious, did the guy who raninto you demand royalties on the design?

It got dubbed the barbique plate so we had a sausage, a sav & an egg painted on it, really.
aaaaand, let me guess you wore an apron over your race suit....

 I'm big on getting the cg forward of half way & the cp as far back as possible, it just makes sence to not try & shove an arrow backwards. I've seen too many back heavy cars come unglued at the salt. You can put a lot of lead down in the steering cavity to weight the front up without unloading the rear, which is what would happen if you put weight in the spare wheel well. The cp is going to be tough to do much about on a beetle. Hitler never thought we'd be racin these things, but I believe the tail will help. I'm not sure who came up with the tail first, me or Porsche, it was about the same time. They had fences & spoilers & all sorts of stuff on theirs, we just had painted food on our barbique plate.
 Ya know what , that gets me thinkin, I've never seen a good old ozzy style barbie up here on the big island (US). You know what I mean, a pile of bricks with a hunk of 1/4 plate on top with a fire under it, I miss that!
 I ran into a bloke from WA at speedweek this year & he said to me " you've been gone too long mate".
 I think he was right.

Hey Doc, That little episode turned into a bit of a blue in the pit. Can ya still handle protests that way down there? As for racing suits back then, what ever you were wearing was good but stubbies & thongs were out. & for the dummies, stubbies are shorts & thongs are flip-flops, not to be confused with the other thong!

Dr G - whenever I walk past one of the spare Jags that Gary has, I give it a kick and a few kilo's of rust fall out. The car now has a red ring around it and if you push on the rear bumper the whole car distorts. If we wait long enough, we won't have to unbolt the engine.....!

LOL my Mk2 is deceiving - it's actually pretty solid, it just looks like a complete POS. The PO's niece decided she would help her uncle 'restore' it by sanding half of the paint off. I almost considered it for the salt as the interior is shot (got quotes of 2-3k just for re-veneering) but couldn't be arsed to do an engine rebuild. Was getting it ready as a daily driver, but too many other projects got in it's way. One day it will live again.

Love the Shaguar build. but being an ex POM I think I would run a V12 or a 6 in there instead of the V8, but that's just me.

A guy I worked for who was a Jag nut had me put together a Van den Plas replica, painted it ,put all the VdP interior in it ( for some strange reason the original VdP rusted out)....he had the dash and other stuff done...a mate of his was sitting in it at Bob's insistance when Bob pointed out the burl walnut ..." yeah Bob, that's something nice to look at while you're waiting for a tow-truck"....all dead pan.

I posted this over at the DLRA forums, but thought I'd stick it here too...

OK, Think I've decided to go with the 915 box. It's pretty much a no brainer really - a new box will cost me big $$$$'s but the IRS conversion will cost me next to nothing. I've resolved myself to the fact that cutting the car is the way to go. Just need to source some IRS arms.

Also the 915 box will do for the first outing with stock ratios. I will play about with a different final drive for the following year after I've figured out what works / doesn't etc... This is what I've managed to figure out so far:

The gearbox is from a Stock 1983 Porsche 911 SC - here's the specs

Top Speed : 146.02223mph
Power : 201bhp @ @ 5900 rpm
Torque : 267.0 Nm (197 ft·lb) (27.2 kgm) @ 4300 rpm
Final drive : 3.88
Top gear : 0.82
Rear Tyres : 215/60 VR 15

Radius of rear tyre is 319.5 and the circumference is 2007.48 - Taken from handy calculator - http://www.carbibles.com/tyre_bible_pg2.html

The tyres I'm planning on using are Goodyear LSR's the smallest ones have a circumference of 2111.

So from a little maths the difference that the additional size makes takes theoretical top speed up to 153 mph - for a stock 911 SC runnning at peak revs of 5900 rpm

My main differences are that I have a little more power (hopefully another hundred horses) but probably less revs (I want to set rev limit at 5500 as I don't want to overstress the engine)

This means that theoretical top speed is brought back to 143

All of this is obviously dependent on being able to get the car to that speed (grip / weight / drag / wind etc) But I guess i won't find this out until i get the car out there.

I'm pretty confident I can beat 100mph which is all I will commit to for the first outing, but I would like to think that I could better this by some amount.

My only decision at the moment is this.

Ultimately it would be great to take the bug to 150 - this might take some years to achieve. So do I opt for the taller tyres? (2283 circumference) as this would equate to a theoretical top speed of 155 with the stock 3.88 R&P.

Thoughts. opinions?

Cheers

Mick.

Hey Mick,
 It's easier to turn a big tyre than it is to turn a big gear. If you have ring & pinion options, start with the biggest tyre you can get in the fender well & a gear you figure you can pull, then you can move up in the gear department if you run out of R's. Plus you're only buying one set of tyres.  Sid.

There are both different R&P, and different gear ratio options for the 915 box - unfortunately they're not cheap - but they are widely available.

I think I'm leaning towards getting the taller tyres and leaving the box with the stock ratios for this coming year, and then figuring out where to go from there. Someone on the DLRA has suggested using VR / ZR rated tyres due to cost, so I might check them out but have a feeling I won't get same rolling radius as the LSR's.

OK bit of an update....

Finished stripping the shell. The doors, glass, wings interior etc are all safely stashed in the garage. Next stage is to unbolt the body from the floor pan and raise it up on trestles so that the floor-pan can be rolled out from underneath it.

Once the pan is out I will replace both pan halves as there is not really any point in trying to patch up the existing ones. I will also trial fit the 915 gearbox as it's easier to do this with the body off, but I will need put the body back on to check clearances before finally mounting the box in position.

When the pan is sorted i will re-mate it to the body and send it off to get the cage built. One benefit of the bug is that the body can be lifted to weld the tops of the cage - no holes in the floor pan required.

There's more wordy stuff over at my blog - http://www.vdubber.com/blogs/entry/Stripped-Naked

Here's a few pics...

Nah, Stainless -- can't you tell that the photo is a reverse image?  The writing on the windshield is backwards, too.

Oh, that's what it is! I thought it was just written in Australian and that's why I couldn't read it!
