Not to mention with a solid lifter, the cam profile can be more aggressive (ramp rates and opening times), solids will make more power. |
something's whacked if your throttle is changing oil pressure independent of rpm
I'd go so far as to add "shim-under-bucket" solid lifters for revving to 10k. I'd be nervous revving the heavy over bucket shims to high revs for extended periods (higher gears) Nice build Tom. :bigtu: |
I wondered when you were going to post this up...
PM me if you are going to part with all the old stuff ;D (At least the mani/downpipe)... |
to the op, im loving the manifold you are making
i have a quick question, what the difference between a 3 angle valve job, and a 5? i just noticed u had a 5 done, and ive never heard of that |
Better flow past the valves and better seal do to more contact points.

Electric water pump! You could even set it to run a min after shutoff to keep the turbo cool, like the new TT BMW's.

especially when the torque starts dropping off after 5-6k based on dyno charts.
well let's see if Brian did a good job choosing cams before you say that :noob: |

an ideal valve seat cut would be a smooth radius for flow but since that's virtually impossible to produce for cheap, shops will cut a series of angles to simulate the round edge. the more cuts, the closer the approximation is to a smooth curve.

very nice mani. i like it very much
