  1. yea blacktops run 11:1 and on a link you can still push a lot of timing into it on 98. So I'd say you could go abit higher

    edit: ^ we posted at the same time boe, I'd say thats largely due to the combustion chamber shape

  2. OS = bunch of good cunts cheers to admin for organising it all was awesome. Shit yea track day ruled would be keen as for another soon, would give me motivation to get a better engine it my car.

  3. talked to a guy at corsa motorcycles today, asking about bike carbs etc, he was saying the main reason he thought bike carbs would work is that they flow so much air(12,000 rpm has alot of air), seemed like a reasonable explanation to me.

    more spam in brads thread, but thats a silly statement a 40mm bike carb will pretty much flow the same as a 40mm throttle body of a 20v which only revs to 8000ish. its all a cost and convenience thing which way you go

  4. yea I was thinking are you just going to drive it on the base tune? because if the base tune is for the stock manifold it will be way out, normal manifold has a linear fuel curve quads its more curved (bad explanation) just learnt that from the 4age and megasquirt days <= probably the least of your worries though

  5. its been discussed on here a little now and then brad put up an excellent article on the Yamaha R1 carbs which seem pretty awesome, I'll try find it. Also going with newer bike carbs is recommended they stay in tune better

  6. yea thats a mean setup you have, the pic you showed is the 26B thats in that link I put up which made the page to wide and gay. Yamaha has a two stage setup on there bikes now where instead of the trumpets retracting in length they pull 'in half' sort of to give a shorter trumpet its pretty cool. Wasnt saying to implement the veriable trumpet idea brad just saying its cool! and if I owned dyno it would be mean to setup for a hp or two!

  7. haha should look into getting them full variable instead of two stage, check the picks of the mazda lemans 26B uses what looks like a electric window motor and a cable and pulley system I would post the pics up but there huge!

    787B stuff

    Would be a prick to setup I'd say plus would need countless hours on the dyno but dreams are free

  8. its at kihikihi theres a silvia round the back there light green colour dunno what they'd charge probably around $50, the guys are sweet once they know you but can be cunts/don't give a shit

    also might want to take someone with you to help move the car around thats on top of it you cant open the bonnet much
