crow cam - Page 2

jonbays · 23-08-2006, 06:18 PM

Thats a slight exageration but the specs are 2232549 IN.24/66 EX.62/20 270 263 210 200 .476" .450"

Thats the lift 0.476 and 0.450 for inlet and exhaust.

Stock AU cam has 0.444 and 0.476 AU XR6 has 0.476 0.456

Nothing wrong with a Crow Cam make sure you select the right one.
Bigger isnt always better.

well guys, i got the crow cam 2232522 with help from evilchief for a much better price than coventrys could offer me and its goin in this sunday. i will inform all of you guys about it after i put it in. i should be going for a dyno run soon after as i am getting my gas system tuned up.

TheSneakiness · 24-08-2006, 10:49 AM

To whoever has/had the 2232550, how much did it cost you?

I like the sound of it.

i bought it $420, however i also installed the crow vernier timing gear, cleaned up the head, ACL gaskets around, extractors and a POD filter
however i cannot gurnatee that that cam will run fine with every stock ecu without retuning!

Cheers

EDIT: Fixed

So, just say I get one installed, and take it to the guys who tuned my Unichip, that it could still not run properly?

yes the unichip HAS to be retuned once u change the cam. I was referring to if you like to try and run teh cam without chip ...

TheSneakiness · 24-08-2006, 11:20 AM

Ah. Now I see.

I did realise that beforehand, and the chip is probably due for a retune anyway.

Baboon_AU · 24-08-2006, 08:26 PM

how often do u have to get your chip tuned and how much does it cost each time?

EvilChief · 24-08-2006, 08:41 PM

ideally once it is tuned it should be right, having said that, it may need adjustment between winter and summer months. after u have gone through each season it should be fine.

thats the beaty about the haltechs, it accounts for air temp differentces as well, orany aftermarket ecu for that matter

Baboon_AU · 27-08-2006, 06:30 PM

okay guys, today was the day i put my cam in.. all was going well until i hit the timing chain tension part. i couldn't really figure it out my self so i called on a mate who is a mech at ford. he explained to me i could do it without the tool but he doesn't recommend it so he will bring it home from work next friday night so i can do it on saturday..
i was so annoyed.. typical thing for ford to do...put parts that can only be worked on by them

jonbays · 27-08-2006, 06:48 PM

it's just a long allen key that and biro tube is all u really need to lock and unlock the tensioner.

To be honest once you have got the vernier gear installed then remove and replacing a cam is easy and you don't have to touch the tensioner just be bloody careful and keep the cam chain and sprocket lifted up as you swap the cams. Takes two people who understand thats all.

Baboon_AU · 27-08-2006, 07:07 PM

well first of all i am a mechanic, and i do understand and the allen key doesn't do it and the tool sets a certain tension on it.
i dont wanna do it dodge, i want to do it correctly

EvilChief · 27-08-2006, 07:58 PM

i zip tied the chain to the cover to keep the tension up when i reasmebled the head, worked like a treat. i also replaced the tension guides (chain guides) while i was at it. $15 dollar part that wears out after 150thou. one piece operation.

Baboon_AU · 27-08-2006, 08:15 PM

yeah i had the chain zip tied to the cam gear ready to slacken the tension off but to be done properly you really need the tool from ford

EvilChief · 28-08-2006, 12:19 AM

that i have

FS5 · 28-08-2006, 08:11 AM

baboon au if you are not fitting an a justable cam gear .there is no need to take out the chain tensioner .you just need another set of hands to hold the cam gear up tight while you remove th e cam and slot the new one in .this is what we did when i slotted my last cam in .it took no time at all not having to dick around pull all those bolts out of the power steer pump and fildle with the tensioner.

Futura01 · 28-08-2006, 12:35 PM

Can anybody make sense of these specs for me ????
Being trying every cam joint i can think of for a mild cam that will give me a very balanced power output through the whole rev range...?

Stage No: 2
Description : Slight lope at idle, good broad power band with strong mid range power, suitable for slightly modified engines. Min comp ratio 9:1.

RPM RANGE 2000-6000
Cam Timing in: 20/60 Exh: 60/20
Advertised Duration in:260 Exh: 260
Cam Lift in: 265" Exh:265"
lope sep : 110

TheSneakiness · 28-08-2006, 12:54 PM

Which mob is that cam through...???

Futura01 · 28-08-2006, 01:21 PM

camtech australia !

I wouldn't put that cam in your AU.

Reason being is that it's listed under EA-EL, which have rocker ratios of 2:1. AU is 1.8:1.

Also, it's not going to fit in the AU head...

EvilChief · 28-08-2006, 02:40 PM

diagram to give you an idea ...

am chasing down factory specs as a comparison at the moment

EvilChief · 28-08-2006, 02:47 PM

STD AU
Cam Timing In: 181 Exh197
Advertised Dur: In: 233 Exh: 246
Cam Lift In:.247 Exh .269
Lobe centre: 119

Cam Tech
Cam Timing in: 20/60 Exh: 60/20 (i am not sure how to read this)
Advertised Dur in:260 Exh: 260 ( a fair bit more duration)
Cam Lift in: 265" Exh:265" (more lift in intake, about same on exhaust)
lope sep : 110

Those cam specs look like they are nicely suitable for a turbo or SC application, would require overlap timings ... and as mentioned above check for rocker ratio as well

Futura01 · 28-08-2006, 03:07 PM

Yeah the stage 2 advertised on his website is for earlier model e series falcons but after ringing malcolm from camtech i asked about it and the have a similar version for au falcons with same specs...
He estimates with exhaust and headers and cam 20% more power.???
But actually i was hoping for a little more then that ??

A little stuck at the moment on choices??

TheSneakiness · 28-08-2006, 03:50 PM

If you get it edited/chipped, you'll find around 8% (going on mine) total power gain on average across the range.

Futura01 · 28-08-2006, 05:03 PM

how does that cam look on paper though !!!!

From just above...

I'm not going to comment on it as I read it here. I'd have to see it in action.

that comments i made only bacuse from exoerience turbo cars respons well to high lift and little overlap ... but i am sure it is a great imporvement over the stock cam. once again being an engine, it woul dhave to be tested as per engine as every engine is unique to its requirements

El cams can get away with waaayyyyy more overlap and duration. the reason ya can't do the same with au and ef is cause of the coilpack. Spark is fired once every 360 deg which means that the plug fires on the exhast stroke too. this is called waste spark and if duration/ overlap is too large you will get poppin and big bangs goin on. I found out the hard way years ago when we put a ed cam in an ef ( there were no ef grinds back then) because of waste spark ignition system you are limited to how wild you can go.

hows the cam doing baboon
