Well, I will ask the question again...What about FI applications? I will be doing a cam swap in the fall. Right now I have a 4.5# Powerdyne, but it will soon be 6#. I don't mind a little lope, but I want some low end since this is a daily driver. Thanks!

 

ok im cam ignorant and this is teaching alot but....

i have MTI cam they recommended as I wanted a little radical...they recommended 224/224/561/561 112 seems same as TR224 to me. I have their stg 2 heads(dual valve springs.

how does this cam difer hp/tq wise to there b1 hammer etc? whay did they recommend this to me?

when will i need to change valve springs?

 

TTT There have been a LOT of cam questions lately!

 

Are there any cams that you would recommend to use in a 422 other than the R1? Maybe something with about .600 lift?

Are you wanting something larger than the R1 duration-wise, something with better idle quality??? I had the R1 in my 383 T/A. I believe Colonel's cam is a single-pattern 240 w/ .612" lift??? Don't quote me on that, but it's right around there. I wouldn't really recommend that cam unless you're going to mostly race the car at the drag strip.

For drag racing a stock 346 the Hammer cam is a good bet, but for street/strip daily driving I'd take out about 14 degrees of duration on the intake on a 112 LSA and you would see alot more torque.

I've done this and the amount of TQ you pick up before 4500rpm is crazy and you only lose a little HP.

that's just my thoughts.

Guys which of these three cams will best fit my combo.

224/224 561/561 114

221/221 558/558 114

222/222 566/566 114 or 112

I looking for a good street/strip cam that will get me into the 11s and also pull real srong from a roll on the street. Note I do have stock heads but I will get custom tuning done. Thank you in advance.

Daily driver/drag only/weekend car with street races?

The next step up from the R1 is (I believe) the S1 which is 244/244 around .600 lift (I think - can't remember exact specs). That is going to be very big for a hydraulic cam, and you will have fun keeping it idling. The R1 which I had was originally a pain in the *** to keep idling and not stall every time I hit the brakes hard, but after some recent adjustments at MTI, is actually fairly tame with a sexy lope. And good enough to put down 495 RWHP on 315 Nittos through a 12-bolt. And good enough to get 24 MPG on the highway.

 

Are you trying to say the hammer cam is too much for the street..? If the hammer cam is the tell all how come everyone is trying other cams.? Taking 14 degrees out produce more torque? Hmmmm.. I need more information than that.. Sample specs would be nice so I could either laugh or agree..

 

Weatherguy I bet that is one awesome ride with 495rwhp NA..

 

Slammed Vette: Do you think the 222/222 566/566 cam with 114 be to much for my A4 with stock heads. What I'm trying to say is
will I be able to use the C1 cam to it's full potental?

I'm getting ready to swap cams for the Comp XE-R 224/224, .581"/.581", 112 LSA, and I have an A4 as well. With custom programming, the cam will be very livable IMO. The 112 LSA will offer more mid-range power over the 114 LSA, but where the two cams peak with HP should be very close to the same with stock heads.

 

I've been looking thru some old post and I see a bunch of B1, C1, and T1 cam owners who have dyno'd 420rwhp and up with 3.73's, 4.10's, and 4.11's. This was all done on either Ed Wright programming or MTI's programming.. If I were to draw a conclusion on the above I would think the only thing that has changed is ls1edit. I wonder what those same cars would dyno with ls1edit tuning? Many have told me that switching from the T1 would net me minimal gains. After further review I have come to this conclusion as well. Many have swapped cams to either lose or gain very little over what they had. Cost effective is the key here.. Like I said b4.. I am no stranger to change, but throwing away money is another thing. I have already thrown away too much. Just my 2cents..

Ok, I gotta question. I'm in the process of getting the parts together to build a 422. It'll be in an automatic. The heads will be 6.0L truck heads with 2.08/1.6? valves.

I see the R1 being recommended. .560/.560 232/237 114

What if the lift was increased to around .580-.590 and the duration backed down a bit. Wouldn't it idle better and have as much or more potential to make power as the original R1.

This may go in a truck so torque would be important. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Would putting the cam in advanced a couple degrees help with torque? The HP peak should move down a bit by advancing the cam also right?

Thanks

Whats a good cam for stock heads?

I would like a good midrange cam cause I would like the shift points to stay close to stock. I don't mind going a little higher, but I don't wanna have to rap it out everytime I go down the track.

I see good results with RATs car with that G5 cam. Of course, I wouldn't see same results, but hopefully similar to his with my stock heads A4 car?

 

XLR8NSS - With a 422, you're going to have plenty of torque no matter what! If you decrease the duration some you'll definitely get a better idle, and more lift would be great with those kickass heads. Comp's XE-R grinds should work well since they have the lift you're looking for, and they offer a ton of different cams. They offer a single pattern 232 @ .050" with .595" lift, and you could get that on a 112 or 114 LSA. You can see the complete list of cams at http://www.eastfork.cc/images/xe-r.jpg. The 232 should idle better than the R1 since it's not a split-duration cam. I don't know how the ramp rates compare between the R1 and the XE-R's, but you could pick up a little better idle w/ the XE-R if the R1 doesn't have the same aggressive ramps. I'm getting ready to try out their 224 XE-R on a 112 LSA in my A4 SS with stock heads. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Devilbird - If you're wanting a nice all-around cam that will provide great mid-range and excellent streetability, I think the XE-R 220 on a 112 LSA would be an excellent choice. Thunder Racing's 220 cam would be a nice choice as well, and it has some aggressive ramps, too. FWIW, I'm looking to shift at 6,600 with the 224 XE-R.

Thanks for the link Trevor

The XE-R 230 looks like a nice cam. Does a 112 or 114 LSA really make all that much difference with these cams. I've seen the dynos of the T1 and B1 cams and there didn't seem to be that much difference between the two. Would the more aggressive XE-R lobes act any differently?

I'm looking for something that will idle OK(max idle rpm of 800-850) and pass a roller emissions test.(shouldn't be too hard with cats) <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

What type of rpm do you think that cam would make peak power at in a 422? I don't want to spin this thing to the moon. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thanks again

Johnnie

 

I gotta say that since I got the car back from MTI on friday afternoon with the T1 cam installed , its a whole different car, just waiting on my mac long tube headers, y-pipe to be installed tomorrow.....and so far I can't have enough of it...T1 worked for me and its a A4 <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" /> <img border="0" alt="[Pontiac]" title="" src="graemlins/formula.gif" />

 

For you folks that have an A4 daily driver with stock heads, and want a cam that will pull hard to 6,200-6,300 and a [strong] low end torque, why not just go with the following:

Comp Cams lobe #3752/3752
This will get you a 218/218 .527/.527 114 LSA "Custom Xtreme RPM" cam

Use a set of Comp Cams 918 springs and your done. BTW, the .527" lift on this cam will give you max longivity of your valvetrain.

With an M6 car, I would still recommend this cam or a B-1 on a "stage 1 heads" car.

I have a bad feeling these super high lift XE-R cam lobes, or cams with [very] fast ramps and similar lobe design are going to experience longivity problems down the road. I hope I am wrong.....

Just my opinion, thats all...
Ron
