Hammer Cam (C1) for A4 C5?
I'm still mulling over some cam upgrade options - anyone running the MTI C1 (222/222/.565) on a 114LS? What springs? Dyno or trap speeds? These specs seem to be in the 'sweet spot' for a daily driver without going to big on duration or lift.
I would like to idle under 900, no throttle body drilling, small converter, 3.42s, small lope, no surging/stalling, stage 1 heads only, don't want to worry about valve springs breaking, shift at 6500, and still make some power. Thoughts? Thanks!

Hammer cam is pretty popular with theLS1 f-body guys. The ones I've heard have a fairly aggressive lope but tend to make just a bit less power than some of the other comparable aftermarket cams (from the dynographs I've seen). I've never heard of spring issues with this cam.
It's priced attractively though.

The C1 cam (aka Hammer Cam) has a 112 LSA. However I'm sure MTI can do a custom grid for a 114 LSA.....but then it won't be a C1 cam. ;)
FYI, the B1 cam does have a 114 LSA and is just a hair less agressive then the C1 cam.
Here's a quick comarison of a few MTI cams:
B1 = 221/221 - .558/.558 - 114 LSA
T1 = 221/221 - .558/.558 - 112 LSA
C1 = 222/222 - .566/.566 - 112 LSA
One other thing, i've been running the C1 cam for well over a year now and with no spring issues. :cheers:

Re: Hammer Cam (97C5ENVY)
I have been looking at cams in this range, I would like opinions on the split duration cam verses the straight durations listed.
ex. INT-222 EXH-226 .567" LIFT, 113 LSA Will this cam make more usable power/torque.
My understanding is that the intake duration is the primary concern for matching a cam to motor size and duty. 222 to 224 should be max for trouble free 5.7l street use. Does the additional exhaust duration help to evecuate the cylinder? and this is a better match for a bottled up street exhaust system. What you think?
