I have done alot of searches, there is alot of information on this topic. I am choosing to post my own because I still don't think I know what I want to.

I am trying to choose between the LT4 Hotcam, Comp Cam 305, or the XE 224/230 112lsa.


I have a daily driver, A4, plan on having full exhaust by the time of cam install. (I plan on using edlebrock shortys due to the fact that I can get the headers, y pipe, everything for free, therefore I am not considering longtubes)
I have stock heads, want nice driveability, pass emissions, yet have the best power possible. What should I choose?

I already have Comp Cams 1.6 SA RR.

Thanks!

 

If emissions are a concern I know of two LPE cams that will pass...The 211/219 .533/.560 on a 112 and the 219/219 .560/.560 also on a 112. I had the smaller of the two in my 383 for almost 10 years and it passed MDs sniffer test very easily. Its very docile with a little lope, but makes great power down low and decent up top, too (trapped 118mph with 3.42s...) Don't count out the small cams either on power. I ran 11.70s for years with the tiny 211/219 and stock injectors and still got 24 mpg on the highway. (Gas will be $4 plus/gallon for super real soon...)

I'm sure others will chime in on the HOT cam working as well, but I only have experience with the LPE stuff for emissions..

I plan on running a high flow cat since headers, ORY and loudmouth would be far to loud. So either way would any of those I listed and your LPE cams pass emissions with a high flow on it?

 

If you have trouble with the sniffer test, just have a 3" cutout welded onto the y-pipe right underneath the passenger-side rear seat. It'll dump the majority of your exhaust out of your cutout and you should sail through. They'll only catch you if they actually look under the car and see it, and I've never seen an emission inspector that cared that much.

 

I had/have LPE shorties, a random tech Y with cat, and a Borla cat-back. With the 211/219 I easily passed emissions in MD. Actually better than my Pathfinder. Obviously, the car was tuned, etc, but the cam worked great...and did it with the stock injectors, and stock lifters, and are designed for 1.6 rockers. All of LPEs street packages have to pass emssions, even the current LSX series stuff, so their cams are good choices for both power and emissions.

I just freshened eveything and went with a bigger Joe Overton cam and 30lb injectors as emissions are longer a concern where I live now in PA, but the LPE stuff really works well, especially for how relatively small their cams are...

P.S. in MD if you tried to run an open cut out you'd fail because the test equipment also senses leaks in the exhaust...an open cut out is one pretty big "leak."...

Does anybody have any input on the LT4 Hotcam vs Comp Cam 305, vs XE 224/230 112lsa. Which of those would make the most power on 1.6 RR?

 

i have the 503, but i dont have emissions. but if i did i doubt i would pass. but then again i dont have a cat. but i think it very doubtful that you will pass emmisions with the 503 and 1.6RR

 

The HOTcam and 305 are very similar. I'm thinking the XE224/230 would make more power than both of the others, but probably not by a whole lot.

I was real happy with the HOTcam, passed emmissions no problem, got 22 mpg on the road with some city driving thrown in, and had a real nice powerband. I think you'd be happy with any of your choices. If I were you I'd base my decision on which I could get for cheaper.

 

I personally would get a custom cam from a guy like Bret. I'm amazed how well my car drives considering the specs of my cam.

 

I was thinking the same...to get what ever is cheapest.

I guess the power order goes hotcam<comp cam 305< comp 503 correct?

Any idea on the differences of power each of those cams have?

Also what is the exact rpm powerband for each?

 

i know the 503 which i have spins from 2800 - 6200 no problem.

 

Thanks

Any idea on the differences of power each of those cams have? How many RWHP would i gain going from a hotcam to a CC305 to a XE 224/230?

Also what is the exact rpm powerband for the hotcam and cc305?

How high can the stock bottem end be spun? I guess shifting with the XE 224/230 would be at what 6,500 rpms since the max power is at 6,200?

All those cams are going to produce around the same amount of hp. My buddy put down 340rwhp with his 224/230 on stock heads, he let off a little early to so he may of had a few more hp left in it. I've seen dyno's on here of all these cams. I've think i've seen everyone of these cams's hit 340 on stock heads, also think i've seen everyone of them hit about 320-325rwhp also. So it just depends on the setup. A lot of people chose the 224/230 because of the torque, and that is what makes a car fast. To answer your other question people spin their stock shortblocks to 6500-6700 and they survive for a while.

 

Thank you. What RPM would you shift at with the hotcam vs 224/230 vs the CC 305? Thanks!
