Those are some HUGE numbers for a big stalled a4 with 12 bolt !!! Congratulations !!! I am quite impressed with the cam selection. I've been running nearly the same cam since June 09, it replaced my old g6x3 that I wasn't happy with. Too aggressive ramp rate etc etc etc. Only difference is my cam is 113+3 compared to yours at 110+4.
Can't wait to see how she does, agains congrats !!!

Very impressive results. Are you sure your cam came in at 109.5 LSA, was this measured with a cam doctor? Using lifters and a dial indicator is not the most precise way of measuring actualy cam specs, and its pretty easy to be off a degree or 2 just from not having the plunger of the indicator not 100% square to the lifter bore. That 239/251 cam I recommended would have pulled clean to 7000 rpm no problem but the drop at high rpm could be those spaghetti noodle 5/16's pushrods flexing. These LSL lobed cams always seem to provide great results.
Would you mind taking a picture of your lid to throttle body setup? Thanks

also on the cam it has been checked multiple ways and still came up in the 109.x range believe me I wanted it to be correct...called comp and they verified it was on the outer limits of there tolerances on a 110 lsa...now installed and adding up all the other tolerances...ie crank sprocket key...timing chain, and all other slop I don't see why it can't be on a 109.5...but none the less it is retarded 2 degrees to get it closer to the valve events
ordered it was on a 111+4...I am not that upset about it now
...plus the trex is on a 110 too and we know how that beast performs... Last edited by chrs1313; 03-16-2010 at 07:54 AM.

Congrats, Chris. That beast should fly!!! I'm glad everything worked out for you. It will be interesting to see if those 11/32" .120" wall pushrods smooth that high RPM curve a bit and maybe just maybe bump it up a couple of HP...
Awesome build.

`He bought the heads and Yellowterras rockers for 1700$ used.The heads had a real expensive spring package,UPGRADE!! also(cant remember pac### number)but they were like 400 $ alone. He is installing the 11/32 pushrods that did not make it on time for his dyno date,tonight.Same length.
