Ok so Ive made a few changes in the car and gone to the green side. I'm just wondering where to start my main jet settings for a 494 with 12.2 to 1 on a 2 circuit e85 dom. I currently have .100s all round, this is for a first fire up

My setup came with 106,s square I ended up jetting to 110,s,but I have a little more motor and compression. I,m by no means an expert but I tune by water temp.Nice setup what's it in?

If you don,t have a/f meter ,the other method is tune by water temp,while making full pass (read mark sullen's web site) (160) in water box,(170) stage,(180) @ end of pass ,should put you there.to lean no good higher temp, to fat cooler just as bad raises exhaust gas temp.But by all means seek out a professional.It look as though you did a quick fuel conversion,although the kit is good, it cant make every engine happy.....voice of experience ,mark sullen's ended up doing mine 9.90 to 9.63 with his set up .
