Was looking at the 228/228 .588/.588 111 or 112lsa type cams, but still undecided.

Lsa 111 + 2 most likely.


01 ws6 6 speed stock 342 gears.

full exhaust, lid, filter.

Looking for tq and hp mostly low to mid range and want to stay under 6000.

Maybe more something like 228/230 .588/.592 111+2?


Thanks for any suggestions or comments

you would be real happy with a cam like that

My cam . Not sure how it would be with stock heads and I don't have any numbers yet but it pulls hard in the midrange with my combo and is very fun on the street. Requires quite a bit of tuning for good street maners though. I did alot of reserch and had mine ground with 111 +1. I'm running about 11.3 scr and 8.7 dcr with it. I think it's a great all around street cam and should put down some decent numbers at the track as well.

You say you want to stay below 6000 rpm?

I have a 228/234 .588/.598 XER cam on a 112+2 and it peaks at ~6500rpm and still pulls close to 7000.

That being said in my '02 it did 376whp 360tq on just Cam 3.73 gears and ported throttle body with no cats. Now with longtubes and a pair of cats it runs 400/380 ish.

With a good tune the car is easy to drive around town and gets wild when you stomp on it. There is another guy locally who has a 228/228 cam (Don't know the rest of the specs) with no cats and dumped exhaust who said he makes 410 and we're very close. We still haven't had a good long run yet though.

Honestly I'd bet you'd be happy with either setup and the differences between the two are likely less than the usual differences between different cars and your overall package.

There are a bunch of great cams out there for the range you're looking at. I've been very pleased with the street manners of my cam, there is plenty of midrange power all the way up to 6,400 rpm and the idle has enough chop that it is VERY obvious the car has a cam.

wow thanks for the quick replies.

yeah dont want to go much past 6k, I want a stockish power band for the most part.

I am keeping the stock heads, ls6 intake, and stock throttle body. Just want some more tq and hp and be done with it but only want to do it once so I want a medium sized cam which I can squeeze the close to the max tq and hp out of the engine w/o needing to rev is high.

I also wanted a fairly choppy idle thats why the 111 lsa and most seem to have +2 advance for 6 speed cars.

I didnt alot of searching before making this thread and saw alot were doing it with a 110+2 or +3 or even +4. I wanted to keep it tight, choppy idle, and to keep the hp peak down as low as possible near 6k or so. so may even think about just a 110+2

Go 110, and maybe consider 224/228 or 226/230 to bring its peak down some. Even a 224/228 110+2 will peak at roughly 6000 and carry it to 6300 or so.

check my sig, my torque is low thoughits a great cam, i am having idle issues though, sometimes when i stop at stop signs it stalls or when i go WOT and let off the gas, the car stalls.

224/224 .609/.581 111+2

that will do what you ask and more, so much midrange trq you'll swear you have a stroker.

This is a custom Comp Cam XFI/XE-R lobes

thanks for the replies.

at first I was looking at 228/228 cams only and then I saw the dyno chart of a car with similar mods as me and I liked what I saw

https://ls1tech.com/forums/dynamometer-results-comparisons/844525-01z28-cam-only-our-228-cam.html

Then I started researching 228/23X cams

I found that 228/232 cam while searching.

Found these as well

228/232 .602/.576 111 LSA

228/230 .602/.576 111 LSA

I dont mind having to shift part 6k, hell I have missed shifts for and bounced off the rev limiter but I do alot of street driving and hardly go to the track, so I thought 6k-6200rpm is enough for me.

My cam too. Runs great, the power really doesn't kick in till ~3K but after that, it pulls like a monster. Just wait till you hit 5K and up at 100% throttle, it's amazing.

I'm running heads too so that also might make a difference. As far as lope goes, mine is on a 112 and i kinda wish i would have gone w/ a 110 cause i'm all about lope, but it's not a big deal, still lopes. You can get the lope of a 110 from a 114 simply by opening up your cutout(s).

Predator-Z I think is likely one of the best guys to listen to on this subject based on his previous posts. I'm sure he'll correct me if I'm wrong, but it sounds like the XFI on the intake with the XER on the exhaust is a neat plan giving you more time to get air into the chambers. Also from looking numbers from other reverse split style cams they seem to deliver where it counts for stock head engines.

I think he's covered the reasons behind his suggestion elsewhere, but Predator would you mind giving us a brief detail on the benefits of the cam profile you suggested? What your expected power range is and the like?

hammertime

iTrader: (1)

Look at the two lobe profiles for your answer.
The smaller 224 XFI lobe closes the valve at the seat sooner, trapping more air in the cylinder when velocity is low, and boosting torque output in the lower RPM's. It still has the same duration at .200" lift though, so cylinder filling is just as complete. That cam will idle smoother and pull just as hard as the 228 XE-R cam through the rev range.

How would a 228/232 111+2 with XFI/XE-R lobed perform?

WeathermanShawn

iTrader: (1)

Yea, I would stick with Predator-Z's cam recommendation.

I'm running a 228/232 110+2 XER lobes (a Predator-Z recommendation). It definitely meets your goal. Lots of low/mid range TQ, peak HP ~5950rpms (carries to 6350).

But that's with Heads & compression bumped.

If your staying with your setup I would try that 224/224 111+2.

Its always a blast to have that midrange torque..

Good luck..WeathermanShawn..

Darn this is hard, its like picking out a slice of pizza when they all look good

bad6as

iTrader: (17)

yea its hard i dont know how long i read and played with the ve calc and asked questons. if you want a stockish like powerband you need to keep the ivc lower or sooner then later the cam pred z said would work but with only 2* overlap it wont lope hard like you would like mabye a 224/228 110+2

Shawn @ VA Speed

iTrader: (3)

the 228-232 on a 111 or 112 is the ticket,but i would def consider the xfi lobes

DaveX

It's really all about the package. It may not be the best cam for the stock heads and compression so if your not planning on upgrading them you should take that into consideration. I picked it to go with my heads, compression ratio and budget; I bought what I thought would be the best heads with more potential down the road that I could afford. Perhaps PredatorZ or someone with more knowledge about it can explain what would work best for you and why. Or you can download a DCR calculator and play with the different cam profiles to find what would give you the best DCR and valve events for a torquey powerband.

EarlSS

xfi on intake or exhaust or both? I would think the 111 LSA would work better to get the power band down in the rpm range.
