to sitting in virtual trees slinging verbal pooo! Look at the progress we all have made! Pretty much nothing other than using computers.... Oh well, the more things change....

First class dude

 

REAL first class Jan real professional.

By the way why don't you tell them what your middle name is. Is it spelled the same. Many might find it amusing?

Let me tell you why I wanted to know about the head. I am HAND PORTING my own head. So my question if all of you negative people would read was not about who's head it was but what was claimed wrong with it? I would like to know where some may have gone wrong!! There a problem with that? I would love to see you hand port your own head.
Don't worry it a one off head no competition to you!

 

Thank you for spelling my name correctly. And the point to this was

 

Is the answer 50" based on original cyl head flow figures at .300

I thought when I saw this head on the cosworth stand at SEMA that the heads were new castings with cosworth cast into the head somewhere, so why would you want the old heads as exchange?

 

really?

 

which part?

My intake hand ported so far 1)46.3 x 24.40 2)46.23x24.33 3)46.36x24.46
4) 46.34x 24.34 to the main tube.
Simple hand Drill, files and porting stones and wet sand paper.

For the head I have already done my silicone molds for measurements. The exhaust port is really buried. That will be a bit of a challenge but I have done motorcycle barrels that were smaller.

So no competition to you. At least for a part to sell
And as for the seeing you do a port job ?I will sit down anytime with you and see what you really know about porting on the labor side that is.

 

Haven't you noticed that he was referring specifically to a particular head? He is not calling cosworth crap, he is not calling the big valve head crap, he is simply saying that this particular head appeared to have a small amount of grinding done on it and it did not produce near as much of a gain as a properly done head should have. Why take things personally when they aren't even directed at you? How is insulting a single cosworth product or mentioning a bad experience with M7 insulting you?

Do YOU know better than someone who actually used the product and tested the product? Or are you just going to assume that because there is a big name on it that it will do wonders?

 

This is getting stupid. I did not care from where or who's head it was just what was wrong with it. To make the statement it did not make the power is an empty comment. A head should have the correct components and ported for the engine it is going on. The shop doing the port will take in consideration the other parts cam, head gasket, deck clearance of the block, pistons etc. A cookie cut head, which is from most, every vendor including RMW and M7 do not take this in account. How could they it would not be profitable for them. Not to say that they do not have a good part overall.
I was not insulted personally but made the statement about history prior to CNC work.My quote
"You are insulting what has been an industry standard for about almost 50 years. That is hand porting"

Certain vendors fear there small business that someone my copy there parts. So not y giving design information on a forum I suppose is understandable. I was just looking for information on what went wrong with a part and that is the head mentioned in this thread. And NOONE has said why yet it was bad? Like little kids using the word “cause”

 

don't go lumping RMW into the other crowd.... we designed our entire system around our head

 

we ? who is this we you always talked about? And it is impossible to make a system offering it on the retail market to cover all the variables.

Who are you really trying to fool?

Unless you are now offering custom builds for each customers Mini?

And why is this thread once again being turned around by you as yet another RMW ad.

Good game you got going. You should place me on the advertising payroll.

 

no need for you to know who WE is......

also for the record.... we don't offer parts that do nothing for the Mini so your MSD coilpacks are still safe for you to peddle

 

JAn As a performance head provider perhaps you can answer then my question on this thread. What do you think was wrong with the head pictured by ingsoc

 

of course I can answer it.....

but why would I give you that info?

 

NICE REAL PROFESSIONAL

 

 

 

why do you think I owe you anything?

if you are so smart figure it out yourself and stop relying on me to give you all the answers.....


for someone who brags so much about your super gas experience I am shocked you would even bother asking questions....

then again...........

 

Going to SEMA . I will be happy to take you around and introduce you
LOL

You don't owe me anything I should know better then ask you I should be talking to the "we" in your group who it is indicating more and more are the brains to your RMW.

Like I said the next time you go to GOODIES in SAN JOSE let me know we will make a show of our MINI's

 

It's really hard to tell by looking at the head what might be the issues. You have to admit we know nothing about it. There is no information as to what might have been done to the head. Are the valves changed, or are the OEM valves reused, and if so are they changed in any way. What about springs. OEM or replaced? Can this head handle higher RPM levels? Whats the limit? Does one need a different Gasket set for intake and exhaust to match the new port size, assuming the ports are enlarged.

So as you can see since all we get is hype and not fact about the product all any of us can state after comparing the head to a known modified head is that the basic Cosworth head from M7 does not offer the gains the purchaser was expecting from claims made.

 

See this is better
I was looking at the picture and saw good valve coloration and the chambers looked hand finished. But nice. I thought perhaps more information would be informative to not only me but others.

If you talk with the biggest percentage of Mini owners that buy into the hype they also have no idea what they get? All of you should request complete information on parts you get. You may need to lets say buy a valve spring and the original shop you bought it from is no longer around. And yes you can measure a good spring to find out what it is. But why should you have to?

It looks like JAN @ RMW and Peter@ M7 are great salesman

(this statement is meant as a complimentand is my opinion)

 

I know there is other BS going on in this thread, but FYI Nitro, my comments were not directed at you.

 

I'm surprised that most people cant tell what is wrong with the Cosworth head, the answer was in the link a couple of pages back

Then again I have a few flow bench figures to compare to

 

Well that would be a small start. However a head that has a high flow rate does not mean it will make the HP. That comes from creative porting and choice of the other components.

In your case obviously for WOT the in and out rate is better for lower ET's
and a lot of NOS.

 

here we go again with the flow talk and disclaimers

My head outflows the rest and makes more hp and torque across the board than any other combo
