Still recovering from the shenanigans? Looking forward to seeing you make use of that new garage

me too

I have the garage outfitted pretty well, hung some shelves, tools are fairly organized. Not to the point it was, but useable. Haven't heard about the motor. Haven't bugged ray about it though. I hope I do by sometime in March because I need a lot of assembly and shakedown time if I am going to make the NG with it this year. I work pretty slow... I can't just make things work, but try to make sure its put back together as if I'm not planning on pulling it apart again.

I did the ultimate white trash thing and washed it the other day with no motor in it haha. It was looking horrible from sitting and was getting covered in sawdust.

Probably have to start bugging Ray to get it by then

I hear you about taking your time. Lots of little things stalled my build but I'm past that now and it's getting fun I probably won't make NG again this year mostly because of family trips etc centered around the kids graduations.

hey man, i just came on here to check with you about that. i know you were busy with the whole house deal and all. the engine has been ready.. so im ready when you are. also, i did a ton of testing with E85 and the mysteries of knock, engine damage and pre ignition. for knock.. i still never see knock with this fuel. since other platforms do see it.. ill still say that our sensor doesnt like to read it. on a different front.. this fuel is the worst with pre ignition compared to any other fuel ive used. this means you can do a nice clean tune thats perfect.. then make a 4 gear pull and by say the end or third or 4th.. the clowing center and ground electrode light off the fuel before the spark. so regardless of the timing, you end up with damage. the fix is cold plugs with a short ground electrode.. like domestic race engines with big nitrous. i did back to back testing and it ends all of that

wow that is great, I'll send a pm!

Do you have any specific plugs you recommend? That is very good information to know about the pre-ignition!

+1

And does that fall under anyone running e85 or just those with this type of setup and higher?

its just for E85. autolite AR3932 and AR3933.

Does that mean it would be difficult to run a hybrid fuel setup and switching back and forth?

I guess we should try the AR3932 and see if it fouls and then move to the colder AR3933 ? I was running 7 series NGKs before which were probably too hot anyway.

I don't mean to hijack the thread or anything, but I kind of was wondering. How do the AR3932/3933 compare to the CHAMPION Race Plug 694 C53VC. Or is the AR3932/3933 THE WAY to go?
