yeah i know it does seem kinda huge lol, wont idle below 1400rpm lol, although i did try a smaller stick 245@50 and it didnt go aswell, i know it makes no sense but yeah. needs more comp with this cam, I can run up to 39 degrees timing without detonation on pulp95 lol.

rb3torana,(is this Tim) maybe try some of that E85 fuel, it'll need 20% more on the fuel supply, but should handle a heap more timing, works a lot like methanol in its delivery needs heaps more fuel but should gain more power over ULP.

yeah it is lol.
itll be good when we actually can get it readily available in qld, bring on 13:1 comp lol.
with the cam size thats in it it could prob handle 12.5:1 with alot less timing and should make more power.
have to wait and see gota start building a new motor, been through 1 crank(huge cracks in no6 big end gave it 10 lightish hits with a hama and it broke clean off :0)
put another blue crank in it, been in for bout a month and its starting to vibrate again grrr, and yes the flywheel is still tight lol.

Give Marielli performance in Belar st Yamanto or Churchill a call (07) 3812 0544 they sell E85, around $54 for 20ltrs,so ive been told ( they might do a 200ltr drum) we were going to try it before we went to methanol,wasnt worth the stuffing around sorting out the fuel system then changing to methanol.

Mine is done but will need a couple or few months sorting and running in before I get it to the drags.

Probably March or so.

I'd also love to hear how Hayden is getting along. I always watch his work with keen interest, as I have done with Grahame from NZ.

GTR600 , it will be interesting to see how yours goes with a shorter diff ratio.
