Re: cam questions (long)

[aventari <aventari@netzero.net>]

I can't offer a fair and objective comparison because i've never used the
Hor cam, but I can tell you about my experiences w/ the g-grind!

g-grind:
It's a VW factory grind so it get points there in my book. It's got a solid
idle even w/ my p&p head and intake, which is important because the CIS
injection gets pissed at you if the intake vacuum is screwy from a radical
cam. The air flow meter will flutter up and down at low rpm messing up fuel
delivery(and emissions...). 
My engine w/ g-grind starts really pulling at 3500 rpm to about 5500, and
very smoothly. I can rev it to 7000 but its pointless going past 6200
usually.  
BTW I passed CA dyno emissions w/ flying colors w/ this setup and a new
cat, so you dont have to worry about that either. all and all, no
complaints. which is rare! :)

however, I want to get that Hor cam and test it out. I could go for some
more top end, especially after driving my roommates VTEC integra.
The Hor's numbers aren't much more radical than the g-grind, so i'd assume
it's  about as well at low rpm, with a little more kick in the top end. But
that'll have to wait until more pressing concerns are addressed.
