Some more tweaking and finding what it likes best will results in some good power gains.

Good luck..

Allen,
I'll probably be calling you today after i can get my dyno graph and send it to you to see if you have any ideas. Where can I get the .030" shims?
I dyno'd 387rwhp with the same mods(except no HS rockers) with a TR224/112lsa

I've got the same dip in some of my earlier graphs @ 6300. With some FMS tuning it disappeared...

Well that makes me feel a little better. Just need Allan to call me back to figure out how to fix it.

What are the specs on the F13? When is the Futral website going to be up and running? What do you guys think that cam will do in a A4, rwhp wise? Thanks

The max lift after the .030" shim is around .610"-.620" . at 1.800" installed height seat pressure is approx 115 lbs which is low for a good sized cam. When the shim is installed,the RPM range will be exteneded and valve float poin also extended to past 7000 RPM.

This looks like a sign of slight valve float. You could have a slight tuning issue also,but I would take care of the springs first.

I left you a voice mail earlier today. If you get a chance give me a ring or e-mail
me tomorrow as I would like to talk to you about spring/shim recommendations.
I may go ahead and swap out the ones I have since I have to remove them anyways to install the shim, plus they do have about 7k miles on them.
Thanks in advance,
Jonathon
