No problem.
I would like to ask you another technical question. What was involved with the crank scrapers? Does the crank lightening allow you to get the scrapers closer to the crank?
I want to put scrapers on my next motor, but I do not know how well they will work with those damn casting ridges on the crank throws. It seems like a waste without them gone.
Pricey?

The ones in my engines are custom made by my engine builder, not by the company in the link above.

Is 11:1 better than 9.5:1 for E85 use? I’m building forged engine (for F/I) and wonder If I should go with 11:1 Supertechs. I’m only using E85 and its quality stuff here in Finland. 106octaine 80-85% all year round

I wonder what CR the ST 11:1 actually will give on a undecked block since the compression height seams to be lower than stock (at least mine were). With some unshrouding maybe 10.5 or even slightly less. That's if the domes actually are 10.5cc on them.
Yeah, mine are 84mm, I know, but there might be the same design practice on the 85.5.

E85 is magic stuff. All of you E85 guys if you could start over again, would choose 11:1 pistons?
I did E85 test 6 months ago with my old supercharged stock 8.8:1 motor. I didn’t have FMIC only Aquamist WI
- Cut the water injection off and start pushing the car.
- After 15min hard street driving I didn’t hear or log any knock (I had det-cans)
- I add more timing until around 22 deg btdc finally engine starts pinging. And that was with 14PSI boost

I was dreading the installation, but now it looks much easier.
Thank you.

Bottom line is with E85, I can so I will.
No.
No lobe center info was supplied. It's up to me to mess with them on the dyno and see what works. I don't know where they are at now, only that the indexes are zeroed out.

This means that you should not care about the guy who built the motor - he is out of the picture for good. Guy has completely disappeared. Meaning, I know of at least 5 people who have been actively trying to find him for well over 2 years.
