What has Dave Been Up To? 29th AUG 2015: 10.66@126.09mph!!

Well, after the Warwick '06 meet, I decided to make some changes to the car. These include : Purchase some quality nozzles for the fuel system and get it re-flowed, Adding an MSD 6AL, Putting stock width guards on the car, And, upgrading the CV joints. The CVs and flanges were robbed off my crashed Chassis car, and are Commadore items. The drive flanges and stubs have had locating rings welded to the standard items. Some clearancing of the bump stop bracket was needed. These CVs use a 28 spline axle the same as a 930 CV joint. My axles are made by Romac here in Brisbane, and are 400mm long. You can see how I cut a groove in the outer, to reduce some of the added weight. This is pretty conservative, because I dont want a failure. Perhaps I will remove a little more weight later.

I want to use these rods, so it only needs another mm or so and it can go together.

Cam lobes were an issue too, but not any more 😉

So how much clearance do you leave as a safety ?

Depends on a few things Marcus, but never less than a mm.

Case was purchased in 1996 and is a Pauter.
Later ones do have improvements, but probably not as far as clearing large strokes is concerned.

Not bad service life then! You would have stuffed many a mag case in that time!

Won't need sparks Gary......it should run on diesel. 👍

I'd rather wear a Beetle out by racing it than by polishing it!

Dyno went well, but broke an adjuster before the final tune. 265 at the wheels at 7400rpm, so far.
Picked up between 30 and 40hp at the wheels between 4000 and 7000.

Everything checks out cool,
so just upgrading the adjusters, 😉
and the fuel and breather lines will be upgraded to -12.

Before the adjuster broke,
I had trouble trying to adjust the high speed mixture, so have upgraded to a Kinsler K140 lean out.

The lower 4 runs were from older tests, and the top 3 were the best runs THIS time, each trying different fuel and timing setups.

This graph shows the torque numbers as well.
We used these 'theoretical' torque figures to play with different timing curves.
With 16.44 compression, this combination needs NOT more than 20 degrees at full noise.(settled on 19).

This last graph shows a comparison with one of the good runs this time,(277.4),
with one from last month with unfinished final tune (it broke a rocker-adjuster that day, 263.7),
one of the runs from before Warwick '14. This with the smaller engine, but had lower compression but the new throttles(249.4),
and the 259hp is the previous best of the small engine with high comp but smaller throttles back in 2012.

Looks like that new runner length has moved your harmonic up to the where you wanted it (just a guess).

Lovely numbers. 😵

Yes, these programs have paid for themselves again and again.

It lost a bit at 5000 comparing the February test,
but still has 20 more at 5000, from when last raced,
and by 5500 its really on song!

By the time it gets to 7000, the gain was about 45hp!

Can't wait to try it at the track!
