Any head is good head

December 6, 2008

Judging by the size of those ports, we have a very good head on our hands. Prepared by the blokes in Eltham, it promises to be good to rev to 9000 rpm with the steel valves and springs (12000 if we decide to upgrade to stainless… which we won’t… yet.)

It is to be matched with a rediculous cam we’ve borrowed, just to see whether it will work for us. John used to use it, but it was no good foor hillclimbs. It only made power from around 6000 rpm. Our limiter is currently set to only 8000 rpm, but we’ve been told that it should be fine to crank to 9000.

The head will be fitted Monday or Tuesday, and will go to the dyno once we get the vernier cam pulley made. Finally it is all coming together nicely.  We WILL be back on the track in the early New Year!

Getting In

 I finally got around to doing the V8 Race Experience I got for my Birthday nearly 12 months ago! I had a ball, even though all the sessions were running late and I waited for nearly 3 hours for my drive.

Although the torque of the car was vary impressive, it was the braking which I could not get over. Between the ABS, slicks and the warm track, the effect was eye popping.  I had an instructor on board with me, who guided me through the line and the braking points. It was a fantastic way to learn the Calder Park circuit (short course). This means I have a minor advantage over Julian when we finally get to take Bianca out to the Western ‘burbs. The Holden V8 was lapping around the 58 second mark, it will be interesting to see how much slower the X will do it!

Many many thank-yous to the Bennetts who knew this would be right up my racing line.
