Question about the Hotcam I know that the hotcam in an A4 w/stock programming is a no no. I heard there are a few guys out there running this cam but surging and dying out are quite the norm. My question is this. If you did a custom grind with the same specs as the hotcam but changed the LSA from 112 to 114, do you think this would eliminate some of the problems? My LS6 cam does occasionally surge even after drilling the TB hole a few sizes but its liveable. Would my idea work or am I just asking for trouble? TIA.

Re: Question about the Hotcam HotCam Specs:
Duration at .050 intake/exhaust- 217/227
maximum lift with 1.7 rockers- .525/.525
lobe seperation- 112

excerpt from a thread between BLKOUT and 9ball...
from feb 2001...........
LSA is a rough way of telling where your power is going to be in the powerband. Lower LSA's tend to have more torque than higher LSA's, but they also have a rougher idle and need more PCM tuning.
I leave it at this and see what else is said..

What springs? Why not just go with a set of 918s and a comp 212/218. That cam works pretty well w/o PCM work.

I presently have the LS6 Springs in the car which are the same springs the Hotcam comes with.
I'm shooting around a lot of ideas so if you have any let me know. A few things to keep in mind though. I'm leaving the springs alone so I don't have to change them every year. Also, I don't wanna do any PCM work so I can't get anything too aggressive.

Re: Question about the Hotcam What’s wrong with a comp custom grind like a 212/214//.522/.524//115 Trroper cam, or the more traditional 212/218 or 216/220 cams with a 114LSA?
Personally, I’m probably going with the trooper cam.
Can’t you just get Comp to custom grind you whatever you want with a 114 to 115LSA?

I have a hotcam in my A4 without any PCM tuning and my car doesn't die at all. Every once and a while the car will surge on a cold start up, but the surging doesn't last any longer than 30 seconds. I have had no problems with the hotcam + A4+ no PCM tuning.

Re: Question about the Hotcam Dan, you might want to look into one of the milder cams. A 212/214//115 'Trooper' cam is pretty mild, and with that lift it might be okay with the LS6 springs. Or step up a little and run a low lift 216/220/115 cam.
From what I have seen locally, a HC or equivalent will need tuning, unless you want to try to tune by drilling out the TB idle air hole and cracking the TB blade. Even then it might idle like crap.
If you feel like you would like more cam, I'd go two more steps aggressive (216/220 ish) rather than one step (Trooper)...
Basically 22_/22_/112lsa cams become pretty finicky in our cars.
My last cam before this one was a 236/240//111lsa cam man somedays it just never wanted to idle. <img src="images/icons/smile.gif" border="0">

Re: Question about the Hotcam Well at least I know theres 1 guy out there running this cam without the programming. <img src="images/icons/smile.gif" border="0">
Trooper cam sounds like a good idea but could you answer this. My cam supposedly has 3 degrees ground into it so does that mean my LSA is actually 113? If so the lope is hardly noticeable. Guess i've never fully understood how this whole LSA subject works. Anyone?
Is CoolAir Z28 registered on this site? I believe he has the comp cam 212/218 (not sure of the lift) in his car and from what I know its very street friendly.

Re: Question about the Hotcam Thunder Racing has a few cams that around in the .52X to .53X lift range that may interest you.
Some from Comp, 1 from Lunati and 1 Crane (which does not impress me)
I think the Comp 216/220 would be nice and I think would work ok

Re: Question about the Hotcam I'm running the LS1 hotcam without programming. That may be of no use to you, since I'm an M6 car. BUT - I didn't even drill the throttle body plate out. I installed the kit as it comes from PaceParts.com, and also bought intake/exhaust valve seals, camshaft retainer plate, crank seal, oil pan gasket (I dropped the pan and pulled the oil pump and replaced the timing chain while I was in there). I also installed the ASP pullies while I was at it.
When I turned the car over at the end of the install, she popped right over and found a rock-solid idle. It has never given me a single problem, and my motor is 95% stock, except for a few bolt-on's.
It has idled in 100+ degree Orlando traffic with the fans on high and the A/C on blast. Sure, it idles rougher then, but it has never misbehaved in any way. A very worthwhile mod, it's really fun to have that cam and the lumpy idle... it's very high on the "fun-factor" mods out there for me...
