My Road Trip Motor Progress
rick m:
The open chamber head motor lives. It is in the car, running and boy is it fun. It has a ton more bottom end power than it had with the K8 cam in it. All the power is from 1500 to 5500 where I do most my driving. Bottom end torque improved dramatically. The final numbers on compression were closer to 9.0 static and 7.6 dynamic. I am trying to figure out how to load some video I took and will post it later today. The changes have made this a much more drivable and enjoyable motor.
Some of the things I did on the heads was reduce the spring pressure too. I toned it down from 165 on the seat to 140. Backed the pressure at total lift down on the nose from 320 to 280 as I will not be drag racing the motor and taking it over 5500 to 6000 rpms. All these type reductions will help on cam and valve train wear. I use Valvoline VR1 oil due to the ZDDP content along with a ZINC additive during the 500 mile break in period. Put over 120 miles in it yesterday with a few 100 mph road blasts. Has incredible pull in 4th gear from 55 to 95. Surprised a couple V8s yesterday.
Current jetting in the IDAs is 60 idles, 165 mains and 190 air. I was able to back down the timing from the 34 degrees I was running with the old motor combo to 30 degrees. The motors seems to love it. The tighter quench area has really livened the car up and there is NO DETONATION.
Will try and get my motor video up later today. The motor now recovers from doing short blasts and runs back at the 180 degrees I was looking for. I drove it to CE today for their pre-Bugorama open house. Drove very smoothly, no flat spots or hesitations.

Guten Worken mein Herr!

Thanks All Torque. Now I just have to figure out how to get my wmv file small enough to post on Youtube or this site.
