GSC EVO 9 CAM RESULTS DYNO'S Inside!

I'm going to remove the intake cam angle sensor housing with the cam after I loosen the trigger vane bolt. I suppose this is the preferred method.

also plan on removing the timing belt when you do the job. the mivec gear is filled with oil and will more than likly spill on the belt. so treat the install as if it is a timing belt job and then remove the gears and the cams.
Overall the car feels great . I love the new found useable power through the rpm range ! It pulls great in 3rd and 4th where before it wasn't that exciting ! I am going to get some drag strip numbers this weekend at the local 1/8th mile track . I ran it bone stock and went 8.53 @ 83mph with a 1.86 60ft in low 60 degree weather .
So I'll get some real numbers track numbers to see how much the car picked up at the drag strip .

That is helpful - thank you! I was under the impression the hex bolt held the gear on the cam - but its a "cap" and the actual bolt resides under the cap.
Will the oil begin leaking after removing the hex cap? Or when the mivec gear is removed from the cam?

Nice numbers! But what were the gains from the cams alone?

I look forward to seeing numbers of these fully tuned/raised boost, and hopefully you can get a similar car on the same dyno fully tuned/rasied boost without the cams for a true apples to apples comparison
