I'm thinking of the basic tsp224r cam.... but I think I want a little more lope in it.... so I'm thinking of maybe having them grind a 110 lsa instead of the 112...

anybody have any thoughts on this??

There was a guy here in town 99 z28,auto,full bolt ons. He had a 224 cam on a 109 lsa it sounded tough. Even tuned the shop had a hard time getting any good numbers out of it and driveability wasnt so good. Almost like it was over kill... but who knows thats only one experience, yours could be different. All cars respond differently.

well, cams are ground a certain way for reason. the 224 duration isnt large, but it isnt necessarily small either. so....a mild duration like that will give u really good midrange power....whereas a larger duration cam will make better peak power, while sacrificing low to mid power. going from a 114 to a 112 or 110 lsa is going to tighten up your power band, whereas a wider angle will give u a broader power band. street cars like a wider angle, cuz they see a wide range of rpms(making use of the broad power band)...whereas race cars spend all their time up high(making use of the tight high power band). u get more lope cuz theres more overlap..and lope does sound nice. but what are u going to use the car for mostly...street/track/course???

its mostly a daily driver....welll...when I'm not out on tour..LOL
I just wanted a cam that wont be too harsh on springs(getting patriot gold duals)
so I wanted to be in the 224 range at 580ish lift... and the 224R fits that....
but I want a little harder lope....
I had an X1 cam in my other car..and It loped just right...but I dont want an x1 again

i would stick with the 112 lsa. i had the tr224 with .563 lift and a 112lsa. i think texas speed has a 224r cam that has .581 lift on a 114. their 224 with .566 lift is cut on a 112lsa. but im sure u could get a custom grind of both worlds...(224/224 .581/.581 112lsa)
the 112 lsa gave me a nice lope, but i wouldnt go as low as 110 if i were u. i think it will lope enough for ya

I have a 220/220 .581 .581 110 LSA 106 ICL

The tighter LSA will lower the rpm of the power band. I haven't really gotten a decent dyno yet, with shorty headers, ls6 intake, lid, pos y-pipe, cutout being only power mods I dynod 359 rwhp / 354 rwtq. Hp peaked @ 6400 but was > 350 from 5400-6400. Tq peaked @ 4500, but was > 350 from 4000 - 5100.

I never really tuned wot very well, was seeing 12.5 AFR down low dropping steadily to 11.5:1 by 6400. Ideally, I should run slightly rich to peak tq and lean it out slightly to hit ~13.0:1 @ peak hp.

Current setup added Kooks LTs, ORP, ported TB and soon some stage II 5.3L heads, then tuning will start over again and I'll have some new numbers in a few months.

Bottom line, I like the cam. Sounds great, has decent drivability (M6), good tq compared to hp, good tq, etc. No one has ever run this cam before so I'm curious as to how it behaves with full bolt-ons plus heads. Find out in a few months. If I decide it sucks I'll go with something else.

i dunno about lowering the rpm of your power band, but lowering the lsa will definitely tighten up your power band. this means u will only feel the max power through a small window of rpms....where as with a wider lsa, u will feel it thru a broader range of rpms. i like the wider lsa cuz, tho it doesnt make as much power as the tighter lsa, it seems to pull harder all over rather than just at a certain rpm window.

A user by the name of DailyAluminumBlock did that and supposedly had good results. He had a cam ground with the milder comp cams XE lobes with 110 LSA and 106 ICL (or 4 degrees advanced). The cam made a lot of torque and made over 400rwhp at 5800rpms. I think dyno dont mean much unless there is a stardard car to verify the numbers of the dyno. I am not sure if he got any track numbers.

It sounded like the experiement went well but I never heard anymore results and no one else tried it.

All of my results were with almost full boltons (no lsx intake at that time), no EWP, no shortbelt, etc. Car is an 01 SS m6.

That would be me. It was a comp xe cam 224/224 at .050" .568"/.568" lift 106icl 110lsa. The car made hella torque and was fun to drive. I dynoed it with some really crusty header extensions off of open headers. It made 405 rwhp and 406 rwtq. It was making 380 rwtq by about 3000rpm. To give you a reference a 99 z dynoed the same day with a six speed. He had nothing but an exhaust and dynoed 300rwhp. With 4.11s and 3700 or so raceweight and nittos the car trapped 117 mph and ran 12.1s on shitty 2.00 60's in pretty bad weather conditions (the only other cam only car running good mph that day was a tsp 231/237 car with 4.30 gears and he was trapping 118.xx mph with slicks).

BTW, tuning is a breeze. don't let anyone tell you otherwise.

Do you still have a graph of the cam?

Alan Just recomend about that same type cam. Car is used for road racing 5 20 min sessions at WOT. I told Alan that I wanted the Most power, torque and the drivability had to be great beacuse I have to drive 7600 miles in just 10 days. 224/224/ 111+3

No, unfortunately not. It was hosted by another member of eastern fbody when it was available for vieweing. Sorry. This dyno was about 2 years ago.

Ha, ha! Finally, I have found that for which I have so long sought! A 224/224 cam with lower than a 112 LSA. I looked and looked through Comp's web site, but that damn thing is the devil to navigate!

Does anyone know the part number for the 224/224 at .050" .568"/.568" lift 106icl 110lsa Comp cam with their most agressive lobes (XE-R?)?

I'm just looking at alternatives to the TR224 112LSA.

DAPSUPRSLO

iTrader: (14)

There is no xe-r 224 at .050" lobe with only .568" lift. You must run the .58x" lift with the xe-r lobe off 224 at .050" duration. I thought originally I could call comp and tell them I wanted an xe-r ramp without the xe-r lift. They said ok and just gave me a xe lobe (.568" lift).

SideStep

I installed a XE-R 224 (114lsa+2) in a friend’s ZO6. Only other mods were Stainless works LT headers (w/cats). He pulled 406/383 SAE. It is a really good choice of cams.

Don't get "cam spec" drunk like I did. I installed four cams in six months and have a fifth waiting in the box to install.... I don't care anyone says, more cam means more sacrifice. My advice would be set a goal and find a cam that balances that...

Good Luck,

Dude, I'm talking about LSA here. Maybe you didn't realize that this is a resurected thread. No problem.

You know, some peole do search. I could have been like the masses and just started a new thread, "Are there any 224/224 cams with lower than a 112 LSA?"

Thanks a lot for that info! I'm no cam expert, but I wish I could get it with the lesser lift. I want as much low end power as I can muster without going smaller than a 224/224. I could care less if it idles like a demolition derby car!

SideStep

DUDE!!! I was not replying to you, see quotation in my post... You can call CompCams direct and they will grind any cam combination you want... If you want less lift use the XE lobe profile, the lift would be .568 on a 224 lobe...

seadoo

actually, I think i have it DAP?? I will host it on putfile, and link it here!

here is the graph from DAP's cam!

Notice how quickly the curve DIES after 5900. The combination would have made more average power and torque with a 110 intake centerline instead of a 106 ICL. While the low end torque is robust, the intake valve closing point of 38 degrees ABDC is just way too early for best power production. Study the graph carefully and compare it to others. You'll see what I mean.
