A 6-cyl high performance BMW cylinder head being resurfaced on the Sunnen HBS-1300 to correct a warp condition and surface finish measurement with a profilometer by John Edwards @ Costa Mesa R&D Automotive Machine, (949) 631-6376 www.engine-machining.com
can i work for you so i can use your machines all the time? haha i love your shop man good job
I am used to American V-8 cyl. heads and dang, that inline-6 cyl-head is HUGE!!! How much does it weigh? Also, by taking off .010, how much compression does that increase on a Beamer? I am guessing it is minor to null, but there should be SOME increase…
@rb26dett32 – This head usually costs around $75 to resurface.
anyone know what it usually costs a machine shop to do that? I need to do it to one of my heads. Mine is a 4 banger though so I’m hoping it’d be a little cheaper lol.
3:58 : that looks almost sexy after seeing the results after the first cut.
Nice video.
Fine tuning M-Power.
Cool :p
wow it was like pure nikel!!!!!
Great presentation: Clear, concise and informative. Thanks John. Diamond tooling is an intriguing choice … I didn’t think it was used to alum. I’ve used it to machine resin-impregnated graphite, but that’s because it is abrasive.
How much would it cost to have this done?
that was a pretty kool video. thanks
you guys rock!!
Allowing 6 thousands is sloppy work, should be half that.
i just got this mint condition 94′ e320 (dont laugh, i love the old school mercedes =D) it had a blown head gasket, i just took the head apart tonight, and will be sending it to be machined this week, its cool to get to see what they do here! =D thank you for sharing this video! cool stuff here!
I’ll let you be the first one to cut your fingers off when you pick it up then
Answer some of the questions about speed. the car will not go faster, the uneven surface may lead water and oil to leak into each others. you will notice this only in the radiators when oil can be easily recognized. Overheating of the engine may lead to deformation of the head surface
HAHA!!…. i like how he wastes his time de-burring the OUTSIDE perimeter of the face!
he probably did.
I like how in this video you show us how you calibrate the machine and got everything leveled. That was a question I had while watching your other videos. Thanks!
Well, provided that you consider that, when you are setting up the timing/ picking the grade of fuel that you are going to run.
Yes.
yes. .. witch will make the car slightly faster … just a lil tiny bit faster
No, but the compression may increase slightly.
the car gets slightly faster after resurfacing … right ?!
It’s not as big an issue with these heads as it is with cams actually IN the head.
Probably some BMW fans who dont like me…
Yes i have seen BMW heads with cracks and i have always wondered what happend to the camshaft if the heads where warped but as you say, there is maybe a way to rebore the cam bearings to compensate to the warpings. Thanks.
I don’t know who gave you thumbs down for that question because it is quite relevant. They are more prone to crack or break than bend.
The answer is «potentially.» I say that because when the warp happened is not as critical as when the cams are put back. If the warp is not too severe, the cam bearings will need to be replaced. If it’s bad, the cam caps and head will need to be realign bored.
