6400 or lower. Stock heads won't breathe like ported heads so the power band will be lower.

Looks like a nice cam.

Matt98SS

cam will work well

918s are good springs too no worries, then again I like the 941s too never had one problem

Thanks for the encouraging words guys <img src="images/icons/smile.gif" border="0">

I thought you'd say that was too big. I guess he (Tom) was right! Not that I didn't trust him, but I just thought it seemed really big for stock heads. As of now I guess I'll be going with this one then.

Do you think I could get away with an 800 rpm idle? I'd hate to have to go higher...

Guess I'll have shift points set to 6300 or 6400.

I just ordered the same one from IRS this morning. It looked like a good choice based on all the info I've been gathering. I guess we'll see!

my idle is around 900-950 RPMs no big deal with a semi quiet exhaust

I'd ground between 2 - 4 degrees of advance in and see if that helps bring your torque curve down a bit.

I have it on the 112 LSA with a 108 I/C and the idle is a bit rough warm (real smooth when cold) but i'm not fully tuned in.

I'm sold on the C1(Hammer cam) myself. 112LSA should bring the torque curve down to respectable rpms for your stock heads and with tuning you should have no idle probs.

And...the Hammer cam will go hand-in-hand with some head work.

I am by no means an expert, just my observation.

So who else thinks I should change it to a 112? I already have a 3500 stall, so power below that is really meaningless to me. What does everyone else think?

114 will idle better. As it is you are now doing a B1-T1 comparable cam. Bos has a 112 but he has an M6.

Yeah, I've heard his car. It's pretty rough. I could probably deal with the idle if I thought dropping the powerband was necessary, but I'm also running a converter that makes pre-3500 rpm power useless, and my shift extenstion is 4600rpm+ so is dropping the power a good idea? I'd be willing to shift at 6300 to 6400 with the 114...

BIGBOS

Whos cam are you going with...

the 114 lsa will be good for you, you will peak a little higher...

I talked to izzo when I had a gauge installed about the 941 springs...(the ones I have and many others have) I was the first person izzo has had that has broken that spring...he then tells me that two more people had the same exact problem as me...under no load what so ever they decide to break....

If this occurs again with me I will be switching to the 918 springs...or some K-motion springs...

Is izzo the one doing the install for you?

Raughammer

The 112 will keep the power around 6500~6400.

the 114 will move it up a bit...

The 114 will idle smoother.. but the 112 Hammer cam idles pretty good...so that really shouldnt be an issue.
For the street? I recommend the 112. For a high revving motor (more than 6700)the 114 would be a good choice.

The (C1) Hammer on a 112 makes power where you want it while giving you good mid rpm torque. The 114 would sacrifice some of that mid range for power at the very high end. (do you want to spin the motor that high?)

The 114 would have less tuning issues to deal with... if you never planned on PCM work. But if you do plan on getting PCM work done to take full advantage of the cam.... 112 baby, 112!

The cam will work GREAT with no head work... and even better when/if you do the heads. Heck, it sure has worked for me.

Good luck.

Brian, yes Izzo will be doing the install and it’s a comp grind.

Raughammer, thanks for the further advice. So if I go with a .563/.563//222/222//112 and custom tuning you think I’ll be pretty much issue free? I don’t want to rev past 6400 at most. Will that duration and LSA pass emissions and not burn up the cats? Thanks for your input.

BIGBOS

Yea it will pass emissions and it will not burn up the cats....

Identical Cam to mine if you go 112.... <img src="graemlins/gr_jest.gif" border="0" alt="[jester]" />

I made peak power at 6300 on the dyno...it was still climbing so I figure its good all the way to 6600 but I shift at 6300... <img src="images/icons/smile.gif" border="0">

6300 sounds great. But you have longtubes and I'll be working with MACs. I wounder if I should shift at 6200 or 6300? 6400 might be too high. I know that I need to see a dyno, but being an auto means that my shift points have to be deceided on when the computer goes in. I'd like to get it as close to perfect as possibile the first time. I don't want my computer going back over and over. Where would be a good "guess" for MACs w/ cats, common bolt-ons, and a 3500 stall (stock heads and intake) with the 112 version?

Yes it is. Because you really want good torque by 3000 - 3200 because you don't have a T-Brake so you can not fully stall the converter. Like Raughammer/BigBos said, even with the 112 LSA you'll make power all the way to 6300, so you wouldn't want to shift any earlier. 112 is good for an A4's performance off the line; you just have to be willing to live with the idle and possible tuning issues.

When you say tuning issues, you mean if I had a stock PCM, right? I’m going to get it tuned for whatever cam I get, so as long as that fixes the problem I fine with it. I’ll have the PO300 code removed to to keep the converter happy <img src="images/icons/smile.gif" border="0">

Will I still have “issues” even after the PCM is tuned?

And where do you think I should shift at with my setup (listed above)?

Thanks.

I am getting the 218/218 .563/.563 with a 114 LSA from Tom. The cam has arrived I just need to have Tom install it. The lower duration at both .006 and .050 should lower the power band when compared to the 222/222 cam. Everything else is pretty much the same. Horse power difference will probably be around 10rwhp but then again I will not have to rev much past 6300. Plus I sould have no problems with emissions due to the 114 LSA and the 218 intake duration.

These are the reason I went with this cam and did not go with the bigger ones.

Just my .02.

RPM. I have stock tuning and S1 heads and am having some issues. EW or MTI should have no problem getting you dialed in pretty close.

I am going to have Cartek do my tuning once scheduling issues are resolved, as they can do it on the dyno with a wideband.
