Yep most the hard work is done. It drives great just need to get it running right. Will be a little weapon when it’s sorted. As for times it was all just exhibition 1/8 mile. The car had been running like shit and fowling plugs all day. On the last run I tried to hold it flat to clear it out and next thing I knew the tachometer was at 7k... whoops. This was enough to throw the v belt, get it a little too hot for my liking and maybe damage the oil pump because oil pressure at idle disappeared. Not a good way to end but all a big learning curve.

Oops.. hard to kill an oil pump, but relatively easy to kill a set of big-end bearings. No growl/knock at idle now?
If you want some carb parts to tune it, let me know. I've got a good range of main metering jets, power bypass valves, venturi sleeves etc that you are welcome to borrow.

One of the first lessons I learnt when racing speedway was that rev limiters are cheap insurance

No it’s not knocking or rattling. I also have the standard idiot light wired in and it goes out straight away so there is some oil pressure there. Spanners reckons the readings I have are normal but I am certain I had more oil pressure previously. I’ll dump the oil and have a look and probably drop the sump and check the bearings.
Once I’m happy with the alternator alignment and oil pressure I might have to take you up on the offer of borrowing your tuning kit.

Yeah it was pretty stupid of me. Created more work for myself but hopefully nothing too serious.

That would be really fun. Unusual to see the Hambsters lined up against anything else... but some grudge racing or test-and-tune runs would be a hoot. What I'll have over them in power they will catch me with less weight. Times will be similar - low fourteens.
Cheers,

Cool vid the guys at overtaking lane put together of the event. They have been following the build and said they wanted to come out so was pretty stoked they thought the car was good enough to feature. Anyway it’s a Really good event if anyone is up this way this time of year. Next year I’ve got to help spanners enter as he doesn’t have Facebook.

Sweet
That orange Williams 2-door was mighty squirrelly.
Either you or Spanners coming to Eastern Creek for the Day of the Drags?
