taft cam question

[gti_7]

hi guys

how much will a taft cam be off when installed onto a square tooth cam gear? i seem to recall 4 degrees but wasnt too sure. i had planned to install it straight up as i dont have a adj cam gear and remembered something about the cam being off.

thanks for your help

Square to round don't matter one bit. They're the same.

Test for you or anybody else that thinks otherwise:
In a spare head align the cam sprocket using the factory arrows. (use square tooth sprocket at this point) Slip off the sprocket and swap the round tooth #557 sprocket* in its place. Arrows are still lined up at the #1 cam cap base.

*(note) As pointed out in the KB here the #690 round tooth sprocket retards the cam 4* I've found these sprockets on later 2.5 engines. Doesn't matter in your case since your going SQTH.

The Taft cams are a regrind and have a 114* installed centerline (S1 and S2) 115* for the S3 if that helps. They should be degreed in.

Woohoo! thankyouthankyouthank thanks awsome news! i can put off worrying about not having a fidanza cam adj gear until i get one now.. so will installing the taft cam straight up be fine? or will i be in out of spec?

thank you again! great post.

I still think until checked, you will be 4 deg retarded. I would still get the gear as it needs centerlining anyhow.

Simon ... I checked it. Got all the sprockets in question right here. If I wasn't 100% sure, I wouldn't post it
