Drivetrain Camshaft Re-Grind
Well, i only posted it to inform dat the Newman cores arent of the best quality...does it matter from which car it is? It is still a Newman cam...and they still use the same material no matter what car its suppose to be on....
P.s. and if it breaks via transit with all the bubblewraps around it..It can definitely break in the head under adverse conditions...and Bryan please stop talking bout my credibility....I have loads! dont worry bout that
ALL he has is a Header/ Cam and TUNE!! Yes?? Those are freaking wild numbers!! great car!!
Just me.....................................

Now for some "NAZRIN" logic............ follow along
so by his "expert" opinion any cam that breaks is a poor design so with this brilliant logic in place let's put it to good use
exhibit A......... stock broken camshaft out of a MINI COOPER..... NOT a MINI COOPER S but MINI COOPER NO LESS
Wow... MINI uses crap foundries.... right Nazrin?
So based on this .... anyone using the stock camshaft for regrinding their cam on is using known parts that fail.............. So how do you feel now knowing you have bought a cam with inferior casting?
I understand the intent of that analogy, but let’s remove the propaganda aspect and look at the reality. Any material defect in the OEM core would be exposed immediately during the regrind process. The NS core’s integrity is triple checked at Crower. A regrind is actually the safest bet.
The rocker roller is many time harder than the camshaft’s lobe, the first place to look if lobe damage is detected would be the roller. In the MINI rocker photo below the roller pin is offset, probably due to inaccurate cross-drill during manufacture. This misalignment caused the roller to be dragged across the cam lobe’s surface diagonally damaging the cam it was acting upon. The needle bearings within this roller were damaged as well.

Jan, just for your info, and a little cam knowledge for you and ure little gang:
If a cam gets one flat lobe it is caused by something doing it to the cam and its not a bad cam. EVERY cam grinder in the world will tell you that
Now, ure credibility as someone who claims to know cam science can also be called to question

The warranty on my Crower/NS1 cam covers a complete replacement of the camshaft and rocker assembly should it show to be the cause of catastrophic valve train failure.
Just wondering if the NEWMAN or other cam shafts for the MINI offer that?

My RMW/Newman cam (whatever the name of the day is on NAM), has been working fine in my 03 for at least the last 20k miles. See's regular track time and consistently run to 7K+ RPM.
Sounds like i should expect it to explode any second now...

The issue with the Newman cam is that there HAS been BROKEN Cams received by customers, and that other Newman Cams ( not in a MINI) have broken while in application, this is a FACT!! However.. the crankshaft on the 5.0 HO Ford engine will break at number 1/5 journal, also.. does that stop 5.0 engines from kicking a lot of BUTT on the track and street?? Dont think so..
Jan has nothing better to do than to NAIL Naz for the true statements.. The BMW Shaft quality is great!! Do they fail?? sometimes.. (I should suspect).
Re-Grinds on a OEM ROLLER Shaft is always a good thing, if the specs can be made to allow a power gain. And the NS series are doing just that.. power gains!! Where is the conflict?? It is between PEOPLE not Product. And that is reflected in the past pages of this post!!
NAZ Has the -1 Cam, he LOVES it ( along with a LOT of otheres..) where is the conflict?? The issues as I see them are all related in the negative statements ... Jan, where are the Cam cores made for Newman?? for OEM BMW MINI?? What is the quality control at those mfg..?? If YOU dont know.. then why try to make others look stupid with statements like that from you, when YOU Dont even KNOW??
WHY have you not posted the results you got with the NS series camshafts against your RMW camshaft.. "They Say....." you have them and were going to run them for a good comparison. Is there a secret in all this?? or is it the same old technique of banter till the truth is lost??
What does mother say?......" If you cant say nuthing nice... Dont say nuthin at all!!"

Your last statement is a joke.

You talk about Jan putting out numbers on the NS cam. Where are yours. You talked about being all set to run each cam the same day. Please get your end done before you start talking about others.

Newman cams and our custom race cams are in all of the record setting cars around the world..... fact.............
and for the 100th time..... why would I copy a cam barely bigger than stock?
you guys are a joke

Why would Jan use specs from a cam that doesn't make as much power or torque as the one's he's using. The dyno numbers he's getting aren't being produced by other cam's... Show me the numbers and dyno sheets for the NS
cam's.
Gotta go this is going no where as usual with no numbers from the other side.

samo--samo.. The car is ready to swap cams on the rollers.. modified the cam Bolt, so I can remove it without having to jack the engine and get the cam sensor out of the way.. pulled the front strut bar.. worked out the cam chain tensioner to be able to collapse it enough and not have to remove it.. so I can remove the cam gear from the cam and lift it out... removed the Nitrous system, all is ready!! yes?? NOT!!
Talked to Tony Of "HP Performance" to set up a full day on the Dyno.. and he is going to be gone till the 10th.. and then I will get the use of his Dyno...
SOOOOoo.... I will be doing it this month... yeah, yeah, I know.. I am slow.. sorry!!

"Duh..... whatcha think??
I am not the one that is against any of these things.. I have NOTHING invested in any of these cams.. I am going to run tests to see WHICH cam I want in my 06. And when I do it I will share the numbers.( probably not on open forum.. do to all the bickering from the NEWMAN crowed... this is just crap!). as for all this character assignation.. this is NAM!! and I feel the usefulness of this thread has gone a long time ago..
but then this is
