• PAW Motorsport offers N54 ported/polished cylinder head upgrade - $3995

      PAW Motorsport is offering a cylinder head upgrade for N54 based BMW vehicles. There is a substantial gain in port flow velocity without a sacrifice in low lift situations. Flowbench charts show an increase of about 35% with gains from 161 cfm to 227 cfm. Both intake and exhaust ports have been ported and polished along with modified intake and exhaust valves. The claimed power gains with the head alone are in the 40 hp range. Charts and pictures are below.

      Expect before and after results on a PAW DCT N54 project car in the next few weeks. For those interested in this upgrade there is a core charge in the $2800 range which obviously is refunded when the core is received.

        AFAIK this $4K head is installed in PAW's 135i race car now with some cams and I don't know if they did anything with it. I haven't talked to them in months. I'm going to make a phone call and see whats up.

        I'm currently working on N54 head with my cylinder head guy and have a few people lined up for testing on stock turbos.

        I'll be talking to the owner of PAW tomorrow during the day depending on my day(doing an F10 528i engine, flood damage). Usually like to go into work and just knock it out asap.

        Don't think I ever said that but I guess I could...I said I'd like to see this on a car first with some numbers before calling/inquiring seriously...will you be calling them to get some numbers or see if the thing is being even used at all?

        I sent an inquiry over to Chris@VAC again and these guys always get back with a decent response and always a reasonable time frame. My attention is towards VAC going forward...

        Here's the response from Chris:

        Will keep you posted.

        Kind regards
