Hit the rollers yesterday. Got basically stock power level results.

I wanted to get a baseline and logs for the upcoming heads and cam swap.

Found some technical issues with the air filter being plugged up and MAF was dirty. I also found evidence of a damaged harness connection at the MAF. AFR stayed between 11.9-12.8 averaging 12.2-12.4. I will get that right before I proceed.

I believe this may have been the source of my cars over enrichment during the run. Melted part of the back bumper also.

Now that I have established the number to beat, I'll be going forward as soon as my parts arrive.

PS the smoke in the background is my plastic melting.

Video link doesn't want to work for me. Just goes to the Byrons World home page with a 404 page not found error.

You've probably mentioned it in another thread, but what you going with for heads and cam?

Weird wear on the MAF harness. Perhaps at some point in its life, a previous owner left it unplugged and it was able to rub against the belt?

May be that one will work better?

I went with a cam motion custom grind. 222/226 .600/.600 117 lsa +4.

For heads I used TMS CNC ported 235cc 243 heads to avoid having to change my fast 92 ported intake.

I did CHE trunions on a quality used set of stock rockers. So everything will be ready to go out of the box.

Btr dual springs, moroso oil pump and a bunch of other stuff like a sexy steam vent kit.

I'm also installing a used GMPP catback with kooks cats that I scored.

After test and tune I'll get the street tune down via Pat Gurerra and do some good dyno logs for him to update.

Then when it cools off and I get new rubber, I'll go play in the mountains and get the suspension further dialed in and hit Yas marina circuit for their super lap events.

Once my parts arrive, hopefully Tuesday, I'll be dropping it off at the shop as unfortunately I'm under some additional time constraints getting my wheel company off the ground.

Should be a nice package when you're done!

Pretty similar cam specs to the EPS cam that I've got - 222/226 115LSA, 0.597" lift or something like that. That cam is dead now, but I anticipate replacing it with something very similar.

Sounds like you have the Pat Gurerra sleeper special. I have the same on the 117 LSA as per his advice for a smooth/stealth cam.

The guys at excess horsepower have good prices on cam motion custom grinds.
