TTT....come on guys...i really need help????

 

I don't know if the LS1 hot cam will pass emissions or not. I would expect it to, but that doesn't mean much. I think there are other cams out there that will make more power and idle better than the hot cam. I really like Thunder Racing's 220/220 cam for a daily driver. It will have a slight lope at idle, and the drivability will be excellent. Even on a 112 LSA, you'd easily pass emissions with this cam and a set of cats. If you're willing to put up with a little more lope, then you could consider a 224/224 cam on a 114 LSA. I would be pretty close on emissions if you went with a 112 LSA, so I'd go with the 114 to be safe. It will make a few more ponies up top compared to the 220/220 cam. The 220/220 112 LSA cam will give you a LOT of mid-range power and won't require high RPM's to use the powerband. I would expect to shift no higher than 6,300-6,400 with the 220/220. You can also get the 220/220 on a 114 LSA if you're really going for stealth. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Sure, you can get the complete hot cam kit cheaper than you can a proprietary grind with springs and pushrods, but I think you'll be quite a bit happier with something else. You could get away with the 220/220 cam and an HPP3 for a raised limiter and shift points with stock tuning on an A4, but the hot cam will be more difficult w/ stock tuning. Click here to hear a sound clip of the TR 220/220 on a 114 LSA through a wide-open Borla and stock exhaust manifolds. It was posted up by another board member ("camss") in another thread.

*EDIT* I just saw in your sig that you have an A4 with a stock torque converter. I would HIGHLY recommend swapping your converter before you do a cam swap. It will make the cam a LOT more livable, and you'll see a better gain from a quality converter than you will a cam. Yank and Vigilante both make a great torque converter, and that's what I'd recommend doing first. You need to have your car working further up in its powerband before you add a cam, otherwise you could be disappointed with your ET results from the swap.

I'm looking for a cam to put in that i can get good power, nice sounding idle, but most importantly, pass emmisions. i've heard that the gmpp "hot cam" will? what all besides the kit do i need to make this work? (ie. pushrods, tuning)??? any info would be a great help. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

Trevor D,
thanks for the reply. i'm having to get a new tranny and i'm going with a bigger converter as we speak. (probably a vig2800 or something like it). I like the lopey idle. what would have to be done pcm wise, to make it work? So the tr224 cam with the 114 lsa will be easier on emmisions? i hate to ask, but what is "lsa"? i'm not real good at the cam specs. i really appreciate all your help man. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

LSA is Lobe Seperation Angle.. it determines the lope.. the lower the number, the more overlap, hence the lope.

 

What exactly is the HP difference between say the 220 & 224 on a 112 LSA? I was gonna go with the TR224 but with better emmisions compatibilty and more midrange I'm starting to look at a 220.

Hotcam passes emissions in CT

Hotcam for my setup and been great. I have
16,000 miles on the kit and had no problems,
with A4 transmission you will have some idle
problems..

 

I'm happy with my hot cam, (2000 SS w/ MN6 ) but I am still working with idle problems,
won't idle with a/c on.

 

i would STRONGLY suggest going w/ something other than a hotcam if you have an A4. it can work, but it is not a happy partnership in my opinion. i have a hotcam in my M6, & it is fine considering what i paid for the kit (i work at a dealership.) but if i was doing it all over again, i would go with something else.
