Cosworth M3's
 

I've did some research on the Cosworth me and couldn't find a much ,I have a set of Cosworth M3 cams I wanted to know if there is anyone runing these cams and how do you like them? How is the iddle?

Anyone?

nasty big bumpy cam :)

but i tell you they breath much better than most cams out there on the top.

Do you run then in your personal car ? Do you know if there is problem with their driveability? Thanks

i have the m3's in my evo IX, a 272/280 combo. idles really good. and they come on fast :)

I suppose they pull really hard up top , how much power gain did did you see?

i ran M2's and i will tell you that even the M2's do not iddle anywhere close to stock but that expected from an 11.0 MM lift cam,, i have many friends running the M3's and they are loopy big time.

with the AC on expect driveability issues thats a given, dont expect anything near to stock ,, but again you should be available to give that up with anything of that size.

i did love the M2's and would not turn back, the top end woke up in a great way, in kill mode 30PSI race gas these cams shinned



GL on your search,,, there is a thread by AMS where Martin tested most cams ,, also talk to Mike @ AWD he has lots of experinece with a variety of set ups.


Iddle is a different story then take off with AC, specially with a heavy clutch.

Ams performed a cam test on many different cams but the Cosworth were not part of the test , on the vid you can clearly hear the lope these cams have , M2's seems to be a bit milder then the M3's but all I hear is good thing about them.

I made the swap from M2's to the M3's after a head/valve problem... I'm on a GT3076 set-up but I immediately felt the top end pull much harder and longer on the back straights of Big Willow and Auto Club Speedways straight away... I haven't got my full race gas tune yet but I did pick up 40ft.lbs. on my 91 octane tune...

and strangely my idle is no different than my M2 cams, stock sounding with only a slight lope every once in a while...

40 ft .lbs is alot of gains specially 91oct, these cams are pretty good cams after all

I'm running cosworth M3's and I suggest getting a full head build before you run them. That said low-end power is ok, but realistically is just not there. You're going to have to wait till about 3400 rpm before the going starts, even on my stock turbo. My FP Black hasn't been in long enough for me to give you a solid opinion, mainly because I ran the black for 3 weeks (drove the car 4 days) and pulled the car off of the street. I haven't tuned the black yet because I'm doing a full rebuild of engine, tranny, etc.

Expect some lag, but when power comes on its full on. They carry mid to high RPM VERY well. They sound good, here's my car at night idling with them:

thanks for the info, now I know how my cams will sounds btw you will love your fpblack trust me

Most wanted was running M3 in his car when he ran the 10.2 on stock turbo, 9.5 on FP Red, and 9.0 on HTA86.

I have m2's and they lope like hell lol
