I really want the cam for 1/4 mile gains and I don't want to spin the motor past 6400 rpm. So would the 110lsa bring torque in sooner and not have to be reved as high? How much more cammed will it sound with the 110lsa instead of the 112? Anybody running it on 110?

I have that cam on 110lsa. It is posted in one of the recent threads in this section but I will post it up tonight

This should also help with a comparison to other cams
228/228 114 lsa = 0* overlap
228/228 112 lsa = 4* overlap
228/228 110 lsa = 8* overlap
232/232 112 lsa = 8* overlap
236/236 114 lsa = 8* overlap

For sure get the 228 on the 110 lsa it fits your goals perfectly.

Thanks guys. And thanks alot 99bluz28 for pm'ing me the document on effects of the lca. It really makes ALOT more sense now and is really making me lean towards 110 lsa. The smaller the lsa the higher maximum torque you will have, the torque will come in sooner, you will have a more narrow powerband, but the stall should help me with that and lastly it will have a meaner cam sound.

Can you explain that to me also??

Basicly I think it is how far it is between when your intake valve opens and when your exhaust valve opens.

It's how many degrees of crank shaft rotation that the intake and exhaust valves are both open at the same time.

I'm at work so I can't post the link but if you search on my post you will find a video of my 228R @ 112LSA at idle and on the dyno.

Anybody else have this cam on 110 lsa? Or have any times with it in an auto?

I would get it on 112 but thats me, i dont think that cam needs a 110 lsa to work well in out cars which is why you dont see many people doing it. If it was that much more beneficial to have it on 110 you would see more people doing it. Just food for thought.

I have this cam on a 114 LSA and love it.

Went that route for the spray. Still sounds like a beast when its loping. Just remember that if you ever choose to spray/boost it, you will pickup less power from the same shot/boost with less LSA. Less LSA will bleed off more cylinder pressure, so you won't see the same gains from a 100 shot on a 110 LSA as you would from a 114 LSA.

Personally I would go with the 112 LSA if I were you, its a happy medium and still boost/spray friendly.

I was in your boat a while ago. 110,112,114 were my choices. I went with 112 being the middle because I liked the lope sound obviously and I wanted the torque curve to come in a little earlier. I plan to run nitrous this year on it as well. I really don't think you would notice much between a 110 & 112 lsa on this size of a cam, if it was a bigger cam like a ms4, trex, etc... then I would go with a 110 or so sure, but for this medium size I personally love the 112. I'm a m6 though also so not sure if that would make a difference, and I have 4.10s

The 112 is better used in an auto the 110 will make the car lobe harder and a little more difficult to get a good solid idle with the load of the torque converter (even though its a 3400 stall) at rest it will make it harder for the tuner to get it not to stall. I think the 112 woulld be a great selection.

99Bluz28

Good point to consider about the stall, plus the lower idle speed of the A4 will give it a more aggressive lope than a M6 with a higher idle. Still a good tuner should have no problem at all getting the tune dialed in.

My tuner wouldn't set the idle any lower than 800rpm on my Auto, and it still sounds beast.

loud exhaust also really opens up how much chop you hear, you could get a 228/232 on 112 and it will have a little more chop then the 228.

99Bluz28

iTrader: (35)

Yeah, even on a 112lsa it should sound good at 800rpm, or maybe just get it on a 111lsa.
Mines at 950rpm and still sounds good.

Well a cam like that has a higher power band to begin with. LSA affects bringing the curve in sooner yes, but it isn't THAT noticeable that you can just say, get a huge cam that normally is 3000-6800 as a power band and just figure you'll get a 109lsa and itll make it 2500-6500 power band. Doesn't work like that, just maybe moves it around some so you'll have a little more torque around 2900 3000 with say a 109lsa then you would with a 112lsa on a cam that size. The lower you go though the more chop, and difficulty it is to tune for idle. This being said, since your a auto I would say go with a 112 and you'll be fine on a medium size cam like the 228r. If you want it really smooth go with a 114, but 112 will give you almost identical lope sound as a 110 would on that size of a cam.
