All the BC cams perform poorly.

 

I called Cosworth, and they said that the m2 cams were designed to work with the stock mivec map.. any comments?

 

can anyone post a stock usdm Mivec map?

 

Sure, it works with it, makes more power with a un-stock map though.

Reference your stock rom?

 

015

 

no he means look at the map in your stock rom!

 

*sigh*

 

he was asking if you guys had it, since he doesn't have it. lol. whats with the attitude??

 

Our attitude?

He's the newbie that comes on the forum and tells us that we don't know **** about MIVEC and we have got it all wrong....

Anyway's there are plenty of places to download stock ROM's, or ROM's with stock maps... my V5 thread for starters...

ps - I don't think your allowed to have multiple usernames....

 

This wouldn't be a multiple user name, my name is Robert... I've been on these threads since 03', Adam is a very good tuner, and a great personal friend of mine, i'm part of the reason he got an evo. He just doesn't have his stock rom to refer to, as his car was originally tuned by a local shop. After getting word from cosworth that their cams were designed around the stock mivec map, he wants to source what it looked like stock as he only has had a modified map to begin with. He's doing alot of testing on mivec as well guys... Granted this might be the wrong thread to ask for the stock mivec map, but you guys could just post it up instead of acting like he's some noob that doesn't know what he's talking about. Spread the knowledge guys, isn't that what these threads are all about? I'm glad i have a VIII, cuz this mivec tuning seems very complex and i respect all of you guys out there trying to improve upon it.

 

He is a tuner and has never seen a stock Mivec map? He hasn't tuned any stock 9's? C'mon now.

Since I feel some pity:

 

brian crower stuff is top notch, I know a guy with BC cams on an evo 8 with green and just and TBE making 386HP on pump no meth.
im thinking of doing the BC 2.4 stroker kit.

 

I can't comment on BC rotating assemblys, but I'd be hard pressed to say his cams are top notch based on the AMS cam test. AMS did a good job of keeping all the other variables constant (boost, timing, AFR) during the cam tests, leaving the actual cams as the test variable. BC cams had less area under the curve and less peak power than other EVO cams with comparable advertised duration numbers. The HKS272 cams made more low end, mid range and top end power than both the 272 and 280 BC cams. Martin also noted that the BC cams required more effort to degree-in properly.

Here's the cam test thread:

Many high profile respected shops have tested Brian Crower cams to poor results.

You get what you pay for, at least in this case.

 

How interesting the thread becomes when informed members begin to post.
