Go on Accel's web site, they just started selling a large cap DFI distributor because they're having problems with spark scatter. The problem is worse with the high power digital ignition boxes.

I beleive you can buy just the cap and rotor, http://cgi.ebay.com/ebaymotors/ACCEL...Q5fAccessories

DonRoc

and I have the MSD Digital 7 plus... I will take a look at there web site. Thanks as allways.

GPM

How did you phase your rotor, centered on the #1 pole at 30 degrees BTDC like they tell you?

DonRoc

I do have the small cap.. I amtaking my son to bed and will get back on this in an hour or so. did you swap to the large cap, for the same reason poping thru the intake 2600-3000?

Their directions don't work with the multi spark, look at MSD's directions for vacuum advance rotor phasing.http://www.msdignition.com/instructi...=rotor+phasing

I meant I'm shooting for 12.5 @ cruise and around 11.8 - 12.0 @ 5lbs WOT. At the boost you're running, 12.3 seemed lean to me. My total advance @ WOT is 27.2 deg. I can probably sneak another degree or so....still playing with it. I run Iron Dart 308s.

To both of you (Don and Jack) - I'm curious about your MAT? Had the boat out last week taking some logs and it was about 95deg ambient air, ECT @ 130deg and MAT @ 155deg at boost. Does 25deg difference seem high? I plan on a new intercooler soon to get those temps down a bit.

DonRoc

I did follow the dfi directions. I verifyed the timing with a light it is right on. I dont remember exactly but it was something with the leds in the dist.
I am going to order the large cab conversion #77095.
I will get back with you tomorrow. I hope its just a head gasket

DonRoc

I got you, I misunderstood. on the dyno it made some more power @ 12.5, I felt 12.3 would be safe eventhough the power droped some.
GPM what is your AF @ WOT?

12.0
