I found these specs of both cams on team-integra.net. I dont know very much at all about cams and I've tried searching. Since nobody on this site seems to run the crane stage 4's and since my new aquired project has the crane stage 4's, I was wondering if anyone here can judge the two by their specs, describe the differences and compare them for me.

CROWER 62404 specs

At .050" tappet lift:
Intake-
opens at -6.0 ATDC
closes at 44.0 ABDC

Exhaust-
opens at 44.0 BBDC
closes at -10.0 BTDC

Lobe separtion 116 deg.

Duration at .050" lobe lift
Intake 218 deg .254
Exhaust 214 deg .248

***********************************

Crane Stage 4 (#16 cam)

At .050" tappet lift:
Intake-
opens at 6.0 ATDC
closes at 32.0 ABDC

Exhaust-
opens at 42.0 BBDC
closes at 4.0 BTDC

Lobe separtion 108 deg.

Duration at .050" lobe lift
Intake 218 deg
Exhaust 218 deg

 

anybody? can anyone at least confidently say one has more top end power than the other or one has more low and mid range power? These are really the kind of answers I'm looking for....and if anyone can school me on how to read and understand the specs that would be even more awesome!

 

crane is crap.

go with crower.

 

I was hoping for a bit more input than that. Any way of backing up your statement? I would love to see more than just an opinion. I read on another forum that their actually pretty similar to one another. My motor already has the crane stage 4's

 

I've had two sets of cranes break on me.

There's no 3rd chances with me.

I've actually never heard of crane stage4's..i was under the impression crane went out of business a few months back..and according to their site, they only make non vtec or SOHC vtec cams. which sucks too

cranes vtec cams never went above stage 3's, i'd assume the same for the nonvtec cams.

crower has been proven over and over to produce good numbers on non vtec setups.. search the crower 404's in the all motor forum only, using crower 404's to search by topic only.

 

The crane stage 4's were purchased back in 2003. I think they were only made for a short while which is why is hard to find out info on them. This engine probably has around 10k miles on it if even that with the crane stage 4's in it. Its never been tuned. only ran hard on a base map. The engine runs pretty decent but I'm trying to figure out if I should expect similar results with the crane cams as the crowers after a tune which is part of the reason for this thread. I was hoping someone could analyze and interpet the peformance and characteristics of the cams based on the specs.

 

This is a pretty late reply but seems as if you haven't been in the biggest hurry.

I personally like the crane cams I had in the past they tend to run a bit more overlap ( intake and exhaust valves open at the same time) than their similar crower counterparts and also tend to have a little less lift (you didn't post those specs).

Have you gotten any farther? What is "built" in your engine? What are your goals?

 

At the time I posted this the engine wasnt even able to run. (long story) Since then I've got the engine running and even drove it around the neighborhood a little bit.

Whats "built"? Here the setup: LS Block, LS Crank & Rods, LS head milled .030, 3 angle valve job, ebay SRI, Skunk 2 IM, JG 65mm tb, 255 walbro, stock injectors, dc sports fuel rail, b&M fpr, crane stage 4 cams, crane springs & retainers, AEM cam gears, ferrea exhaust valves, usdm itr pistons, oem HG, arp head studs & rod bolts, ITR 4-1 header, LS tranny, unk upgraded clutch kit. no a/c or PS. no cat, test pipe, tanabe racing medallion cat back exhaust. chipped P75 ecu from phearable.net

My goal is to get the car road worthy and eventually get it tuned all motor and hopefully achieve at least 180whp

The reason I posted this thread was to hopefully gain some knowledge on how to read cam specs plus I wanted to try to see if my engine may perform similar to the other setups I see on here with the crower 404s

 

does it have any kind of porting? 180whp is hard to acheive with a b18 non-vtec. I beleive you will be around 150-160.

I had the crane 101-012, which are usually compared to the crower 402,on stock valvetrain in a b18b with a 3'' short ram, ebay header and 2,25'' exhaust, street tuned on crome gold. I loved them, I got them with 3 summer's use and drove them hard.

I ran 14,3 consistant in a 1992 integra LS full equip on street tires,

 

no porting has been done. The mods on here apparently dont like us trying to guess hp so I'm just going to have to get it dynoed and see what I get.
I may not not achieve the 180whp like you said, but I'm hoping for the most I can get. I figured 180whp would be a good number to shoot for considering a lot built ls guys running crower 404s get around that number.

 

a 150 whp Ls is one hell of another beast than a 150 whp b16, especially on the highway.

 

Thats probably true because B16 have very little torque. My friend who owned the car before me was on a uberdata base map and told me that one time he ran against an eg with a stock b16 on the street and pulled on him pretty hard. lol I figured it was probably true because this car feels like it has a lot of torque, plus hes a trust worthy friend.

 

High Compression and a shorter geared trans would help you a lot.

 

I'm already at 12:1 comp. but yes a gsr or b16 tranny would be much better

 

you were pretty much right! Got it dynoed today made 150 whp at 7400 rpm and 123 wtrq at 5800 rpm. I'll post the dyno chart later on

 

I hope I can get around that much whp in my ls crx. going with 403's though and a few other different things. how does your low end feel?

 

it feels pretty strong. check out my dyno on my other thread.

what kind of tires exactly were they? were they drag radials?

 

Guy in my area was running a pretty basic setup and made 200whp NA with his LS running the 404's. His head was ported and polished, LS block w/ P30's, Edelbrock performer X IM w/ 68mm portmatched TB, length tuned intake, a RMF narrow header and just tuned to the hilt. That car was fast.

 

crane went out of business for a reason.
if your running the crane cams ditch them before they break and get the crower 404's
