Topic: EC Cheetah Cam Identification, from EC

[fastmow]

So I just ordered and received EC's "Cheetah" cam for my Vanguard v-twin (35ci).  It showed up promptly, few days after ordering.  

But, this cam has no identification on it, besides a hand etched "R" on the gear face.  The invoice shows the correct EC part number of 35-3030, but the camshaft nor the bag it came in shows anything.  

Being that EC offers 3 different Vanguard twin camshafts, how do I know which one received?  Or, how does EC even know which cam they have?

Possibly the hand scribed "R" means Cheetah, not sure.  I could easily measure the lobe lift with digital calipers, but will that be enough to ID it against the two others they offer?

Just going out on a limb here.... uh.... call EC?

[fastmow]

Absolutely.  I have messages into them, we'll see what comes back.  On this post just checking to see if anybody else remembers any marking on their Cheetah cam.  If not, how does EC even know which ones are which in their stock? 

[fastmow]

This is kind of a mess.  I hope it is something I am just not understanding.  Here is their response:
============
the cam is the right one, we stop engraving the cams many years ago due to request from customers want there cams to be a secret

Cheetah is a brand name of precision cams, this is not a cheetah cam it is a cam we develop  we found to be faster.
thanks

===========
From the webpage of where I ordered it from on their site, it says "Cheetah grind".  Above they say now it is not (after it is in my hand).  To add further confusion, the webpage part number of 35-3030 does not appear in their 2015 catalog.

I now have no idea what cam I purchased, or what was sent to me.  Also have no idea how they keep them separated if they show/stock 3 different ones for this engine type, and there is no ID on them at all, or even the bag it was sent in.   

Ugh.....!

check lobe lift should be 305-310.  i got one for a customer engine a few week ago . also be careful since its now made in a smaller base circle unless you mill the head allot you may need longer push rod .

it apear to be better than the original cheetha .we put it on the dyno and it make peak power a little latter and torque was good

i will also add since its still a cast cam without a steel rod inside dont try the rev to 10 000 or you will pick up parts in the floorbord

[fastmow]

Gui, thanks for your feedback.  It was helpful and consistent with what EC has said.   

Since this is not a genuine Cheetah cam, I am going to request to return it.  I believe EC is updating their website to remove the Cheetah labeling from this cam.  I am going to request to return it, since I was interested in the Cheetah cam.

Wouldn't it be nice if you could still talk to a live human at EC?

Wow i understand your frustration, ordering a cheatah cam but not getting a cheatah cam lol But to add to gui's post when using a stock cam without a steel rod i reccomend my client's to never turn past 7500-8000rpm, preferably not to use heavy rockers (such as roller rockers... and i am even going to say cast aluminum ones too but they arent too heavy so you can get away with it) and to run very mild springs that will start floating arond 8000rpm, the reason being: its not a question of if a cast cam will break its when will it break. Thats why i put so much time and effort to make billet cams, cheap insurance  good luck with you build

If the one calling would leave a message with a return phone number the human will return your call.

Not been my experience George

I do believe the "cheetah" was a grind from Mike at precision cams. If the piece ec sent is better or proven better is there a reason to be wanting the cheetah? If the cheetah is what is desired I would call precision cams unless ec has one.

[fastmow]

Right.  So, anybody else have opinions of EC's "35-3030" cam vs Precision's "Cheetah" cam?  This 35-3030 from EC does measure 0.300" lift at the lobe.  Don't know any other specs on it.

[Gui961]

they are pretty close if it was me i would use it .. the ec make peak power around 6800 and fall pretty quick after that and the cheatah peak at 6250 in every combo i have tested and still had something up to 7500 . the ec apear to have better tork its hard to tell since engine combo change that allot.

the engine with the ec cam was not run on a track yet but will be at the aamc next week

both cam are 7000-7500 rpm max engine and with the ec spring is about what you need to run that

imo

[cycloneracer]

If the EC cam makes power at higher RPM I'd run it.

The "cheetah" is to "violent" in my opinion. Hard to control in a twin.  Awesome in a single.  Hated it in the twin.

Thanks for the feedback all.  Exactly what I was looking for.  Now I just need to chose what I am doing for carb(s) [unrestricted class], and we'll be ready to fire it up!
