Yeah we put the 5.0 crown wheel and pinion into the car and its getting alot closer to where we want it to be.

We went up and competed at the rallycross in tauranga earlier in the year. We would love to go up and do the Wairarapa rally one day.

Tune is at about 80% , feels like a broad power band kennelly cam comes in at 5800 and it has another kick at 7200 tune lengths we think. Would guess more than 180hp wants to keep pulling to limiter of 8300

Getting the tune close, worked out that the runner length was critical for reversion after adjusting the length we found a sweet spot where it seems happy.

We are just using the standard gearbox with a 4.4 lsd but we have a 5.0 to go in it which should help

The second event after getting the new engine running still need to do exhaust as it is getting a lot of reversion with the factory exhaust at low revs

Internal diameter of the runners is 50mm and made a spacer to make the air box bigger if needed out of a nylon chopping board. Because it's a rally engine we are going for response  rather than top end horsepower. Trumpets as you can see, not factory. Once we have found the best runner length we might have a go at making some tapered runners.

8500rpm is what we are hoping for but might be restricted because of the hydraulic lifters

Runners are pvc pipe starting with 385mm. And the compression is 12.1 most we could get with out getting serious
