My Flat Tappet Cam Wiped Out So I Decided To Go Roller

LMAO - I'm not going there

C'mon, the fruit doesn't get any lower than that! Plus it was relevant.

I am curious what cam you're running too.

Mine is 212/218 hyd roller. Comp 08-501-8

So, we're both 112 LSA, I'm just a little more duration and lift. Maybe I'll try some more SA at idle. If you don't mind, what does the rest of your SA tables look like?

I know, sorry. It just struck me funny.

I softballed that one in on purpose. What if you try commanding a little richer than stoich? You may pick up some vacuum that way too.

I can try that too. After a few "VE Learns" you can see it was changing my idle at ~50 - 55 MAP and 700 - 800 RPM just getting to 14.7 AFR. This is before smoothing out my tables, I have more VE learning to do before smoothing.

Here's what it looks like when doing it. The EBL will only adjust up to 12% at a time before I have to flash and "learn" some more. Once most of the 12% adjustments are gone I'll try smoothing and then watch it again.

Are you tuning the VEs with Wideband? I had a wideband with the closed loop turned off and the VE adjustments were really quick.

Yes, I am tuning with a WBO2, have CL, Hwy Lean, EGR, and PE turned off. Plus BLM Max/Min is set to 128/128 and CC is plugged off. I just have to run it in more cells and give them time to adjust. I may hook up to a trailer so I can tune some of the higher MAP ones.

Thanks!

I have another issue - when I had the original peanut cam in it, my oil pressure, when hot, was ~40 @ 2000+RPM and 10 PSI @ idle. When I put in the Lunati flat tappet cam the pressures went up 10 PSI across the board. Now, with the Comp cam, it's back down to, or a little lower, than what the peanut cam was.

I'm thinking about putting in a new oil pump (it's the original 22 year old one from Mr Goodwrench), probably a high volume. Anyone have a suggestion/preference?
