Here is the intake manifolds after the VW event 2 weeks ago . I don't really know why they cracked and broke as the data is all fine . One cause is a small backfire in the inlet system after bouncing off the rev limiter @ over 9000 rpm's due to the shitty track and wheel spin . The other possible cause is that the tyre shake has just gone through the entire car and just plain broke the manifolds . Either way , I have fitted another spare set of intake manifolds and I will back the clutch down a little and test it out again this weekend at the Sydney Jamboree . The track should be very sticky this weekend so hopefully I may be able to get the car down the track a few times , ROD.

No boys , I have 2 silicon joiners in the manifold already . I did replace the hoses with some new Turbosmart hoses as they seem to be a bit thicker and stronger than what I was using . Anyway I am loaded up and ready for a good day tomorrow . I am not real confident that it will go quick , however I have my chassis tuner with me tomorrow and we will start adjusting the chassis to take a bit of bite out of the rear end . What the hell that means is beyond me , but we will see what it does tomorrow , ROD.

Well , here is a quick de-brief of what went on last weekend @ the Sydney Jamboree . After replacing the broken inlet manifolds with some new ones I had here I decided to join Ben and Henry for the day . I had the Adelaide tune installed and the only difference to the car was the rear shocks were stiffened a little on the compression side . I went out with an extra 2 lb's of air in the rear tyres now @ 8.5 and the car had a bit of wheel spin off the startline and than went really good . The 60 ft time was 1.29 , 1/2 track was 5.39 @ 135 and full track was 8.33 @ 164 . The car filled with smoke as I backed off and by the time I stopped the safety guy came running over to put out a small oil fire . I had purchased some you beaut fire proof matting for the base of my catch tray , well , it isn't fire proof , no real damage . After closer inspection in the pits I had blown out 4 outer and 1 inner push rod tube seals on one side .
I missed the 2nd qualifier on purpose so we weren't rushed to replace the seals . All data looked good and no changes were made at this time . On my next qualifier I went 1.22 in the 60 , 5.19 @ 135 1/2 track and 8.12 @ 164 again at the end . A little smoke again on back off and this time I only blew out 1 outer seal , on the same side as before and one of the new seals . I mopped up a little oil and compressed the tube and the seal popped back in place .
All data looked good and the chassis guy lifted the wheelie bars a little and re-adjusted the front shock extension . The 1st round of racing against the VS ute I went 1.23 in the 60 , 5.24 @ 130 1/2 track and 8.25 @ 162 full track . I was a little down on this run as I had to get out of the throttle as I shifted into top gear as the wheels started to spin and didn't seem to grip . The data tells me I peddled it twice . All in all quite a successful day that I didn't see happening . The car is ready to go again after I try to modify the push rod tube to fix the oil leaks . The track was very sticky and it is amazing what a difference a good track prep can do when compared to the VW meeting 3 weeks before . ROD.
