Spark plugs?
I just boosted my car on e85. What kind of spark plugs should I be running? I have heard I should be running a colder spark plug?

Im running 10's on mine. Works great, 11's might be too cold. But as long as it starts easy and runs smooth on idle i think you should be fine. JT |
What's coldest? Copper? And is a higher temp rateing hotter or colder?

Im running the NGK R7420 plugs. These are iridium plugs. JT |
I'm running 9's and having issues with the car not even able to go passed 5k it's like it hits a wall and just spits and sputters. I have 10.5's going in to hopefully correct that but out of curiosity, what is a good place to start with timming. I'm running the same timming map as I did on 91 Oct. And wondering if maybe I should get more aggressive on the advancement. Right now at low boost 10 psi it's logging 18 degrees advanced. Would that be a potential problem for the spit and sputters at 5k?

bogging out like that sounds like you are too rich. what are the AFR's when the cut off occurs?

I know this is a bit late but did you figure this out?
Check to make sure that your plug wires are in fact correctly located. I've known a few people as well as myself that have run into that same problem in the past. Wrong coil on the wrong rotor in the wrong L/T position would give you the same kind of symptoms |
