"Parmas" Motor - Toyota Yaris Forums

Parmas · 08-03-2011, 08:11 AM

Thanks for the help guys but I really care about this motor and I prefer being safe than having a wrecked motor for just a few more rpm.

I am thinking of let it run from 6500rpm till 7000rpm and see if it will keep making power and torque on the stock head.

I am thinking of boosting till 16psi for now and see how it goes after trying it on the drag strip.

The main issue in this country is fuel octane since you don't get constant octane from the station. I will be using the Lucas octane booster to tune and keep giving her every refuelling to be safe.

The other issue is tire traction and wheel spin from a stop. The tires are Toyo R888 rally semi-slick tires but still having wheelspin above certain rpm launches. I am trying to set a launch control switch to help with this issue.
