Anybody got the Mini Madness r56 Schrick cams?

 

If you mean fitted and currently running, then yes, although I have these in a modified cylinder head, to get the best from the profile.

 

Worth it?
How deep the mod on the c.head?

 

Worth it to me, as I am looking for every single last available HP, my cylinder head is heavily modified too, with the addition of aftermarket valves/springs and many hours of porting and polishing.

 

Have you had any issues with the ECU, re your head and new cams? I am very interested in this.

 

No ECU issues regarding the cams or head after fitment, I was expecting a CEL light, but again everything is ok, although I did get a CEL light and ECU issue when I put on my larger turbo, so I am doing a little trial testing to see if I can resolve the CEL/ECU issue.

 

Do elaborate on everything you did. I have been wondering about doing this and I would love to hear all of your experiences with it.

 

Razc WE need more info on this "Inside" job.

 

which of the 2 cam packages that schrick offers are you running, do you have a euro spec or us spec car ?


I tried the larger cams without success .

 

Seems like you didn't take into account when you fit the 10.7mm lift Schrick cams, that you needed to increase the valve relief areas in the piston crowns, or fit the thicker 1.20mm head gasket over the standard 0,9mm otherwise you will encounter valve to piston contact.
I have a Euro spec car, with the Schrick 10.7mm lift cams.

 

Are you running the jcw headgasket ?

 

No, I have pistons with extra material removed from the valve relief areas, whilst still retaining the stock 0.9mm head gasket thickness.

 

will need to check part # to see if the jcw has a unique headgasket .

 

razc are you in greece or the uk?R

 

The head gaskets are exactly the same between the S and JCW, just 1 is 0.9mm and the other 1.2mm thick, I am in the UK.

 

cool ,i have the jcw so no need to notch the valves ! I am guessing you are czar ?
Hook me up with a Kart !

 

If your JCW is before 02/2009 then you will have the 0.9mm gasket! I can't definitely say if your JCW pistons will have enough valve relief clearance, so if you intend on running the 10.7mm lift cams, be very very precise on your measurement of valve to piston clearance, you need a minimum of 1mm at maximum full valve lift, anything less and you will encounter valve to piston contact.

Yes I am czar.

 

sent you a pm yeah nam is different lol

 

Yup, it's a good thing we moved on since the moderators that don't respond to users left in May 2009.

czar, feel free to PM me to get everything sorted out.

 

OK, I am getting pretty serious about this, but the whole process of removing extra material from the piston head is going to be very expensive. How much material did you have to remove? Do you think the 1.2mm gasket would allow enough clearance?

Also, how did you remove the necessary material, did you pull the engine, dismantle it and have the pistons ground outside of the car?

Do you think if you go with the 10mm lift Schrick cam that you would have valve to piston issues?

Sorry for all the questions, I am just trying to get my facts straight before moving forward with this.

 

hey, when you do get serious please keep everyone posted

 

.

 

Thanks for the info.

I believe that I am going to need to deck the head. Do you know how much clearance the .508mm extra relief gave you on the 10.7mm cam? Did that take you right to the 1mm required clearance or was there more?

 

Be very careful when considering to machine the face of the cylinder head, if you are going to machine the face, then only take off the very minimum necessary, as there is not much material to play with.
Yes I know just how much clearance I have, and I allowed for and got more than the minimum clearance of 1mm necessary to run the 10.7mm Schrick cams.
Without giving to much away about my particular engine build, the reason I have more than enough clearance is, I have had new blank camshafts profiled to suit my particular engine build.

 

I guess I am a little bit confused. Are you using the Schrick 10.7mm cam shafts or did you have custom cams ground? I am just trying to determine how much clearance you will have with the 1.2mm gasket and the 10.7mm cams.

I think because the tolerances are so tight, that I am just going to go with the 10mm lift Schrick cams and some custom head work.
