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

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.

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

Now its moving! Did you change gear set/final drive? Looks like the package is really coming together.

Any plans for north island rallys?

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.
