Just to let you know, I have read Raughammer's page (4 times), ls1info (3 times), and have used search to many times to count. I have got two pages of hand writen notes, so finally I need your help summarizing.

Need to pass CA sniffer (on a 00 M6), so I narrowed it down to...

MMS 218/218 .561 on 114lsa (safe) or...
B1 221/221 .558 on 114lsa

With stock heads (with valvetrain upgraded).

Q. Between the two, from 4000rpm+ what do you think the power under the curve difference will be?

Q. At what rpm will both peak at?

Q. What do you think the hp difference will be at 6400rpm?

Thanks to all who can help.

Jeez thats an easy one, go with the B1 for sure! I had no real complaints about it in my car (before I swapped it out for a more aggressive cam).

 

I figured someone would immediately jump on the B1 <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> , I wanted to get the answers to my questions inorder to see what I would be leaving on the table if I went safe with the 218.

 

b1..

I dont like the huge lift of the other cam.

just my opinion

Come on guys, help me out here. Educated guesses welcome.

 

MMS 218 cam and stock heads on an A4 with converter unlocked (no dyno tricks).

362 RWHP
373 RWTQ

Made power all the way up to 6500

What was the deciding factor when you chose the MMS 218 over other cams in that range?

Did Ralph install those for you?

LOL Freak I was going to post the same thing. I would DEFINITELY go B1. I passed emissions very easily with that cam.
Cheers,
Chris
ps- The ultimate IMO is the XE-R 224/224 114LSA .581 lift cam. I am pretty sure you would pass emissions in that too.

Ralph did the install and dyno. He's the only one that has ever worked on my car.

 

Since noone took a guess at the difference, I will. I would guess a 5 to 7 RWHP difference betwen the 218 and the B1.This is from all the dynos I have seen on different cams . I would also go with he B1,because it will pass and we always want more later..

Reboot, thanks for the info.

99RedHawk, thanks for taking a guess. I figured bewteen 5-10rwhp.

My main concern is not wanting to rev to high, thats why I was looking at the MMS 218, however If my memory serves me correctly, Rebbot was going to need to shift around 6600 (Reboot, plaese correct me if I'm wrong). That seems awfully high for such a small cam with stock heads. Let alone adding S2's down the road.

Just trying to figure these two cams out.

Any more comments?

TIA. Scott. 00 WS6 M6.

 

I wish Reboot would of posted his before cam #'s so you could get an idea of how much he gained from just the 218 cam swap, it was pretty impressive..Don't know why everyone want's to jump on the B1 band wagon unless that's what your personally using or used. There is also the TR220/561 cam to consider as well. I think your pushing it if you use anything passed a 221 duration if you want to pass Cali Smog IMO. I'm curious if anyone has passed with a 224 duration myself..

 

311 RWHP
347 RWTQ

Pre cam and maybe pulley (I'm not sure if I had it then)

 

DanZ28, I agree 221 is the limit you want to go safely on stock cubes here in cali.

There is no doubt Reboot has made nice gains with the MMS 218, I would have thought that cam would have fallen flat on it's face above 6200rpm. I guess it doesn't.

Now, if I'm going to have to shift around 6600rppm with either cam, I might as well go B1 and gain a few ponies across the range. And may even respond better to S2's down the road.

Reboot, any track times yet, before/after? If not hopefully soon. I bet you're curious as I am.

I've seen 400RWHP with the MMS218 cam, if you're worried about smog it'll be a good choice. Who would know better about passing Cali smog than MMS?

My FLP Level IV tranny just arrived yesterday and should be installed today. I hope to have new #'s this weekend if the weather cooperates.
