picked up a used ramhorn manifold and the turbo flange is a little warped, I hit it with my bench top belt sander to show the high and low spots. Is it ok to just go at it with the sander till its flat or should I have it machined? Aslo it has no markings so If anyone has a idea who it may have been made by let me know, or what you think about the qaulity. thanks

 

I've never delt with a turbo befor but if a gasket goes between the flange an the turbo i would say just use the belt sander

 

Belt sander for sure. I can't see pictures at work, but I assume it's not too bad from how you worded your post.

 

Its mine, I couldn't tell you how long ago. I've been doing split Honda flanges for about 5-6 years. If your belt is low speed then give it a couple seconds on there at a time, so long as you are good at applying even pressure. I'll usually run a multi-ply gasket on the stainless flange. If you want it guaranteed perfect - then machine it.

 

thanks for the help, that means its of good quality and has a lifetime warranty right think ill give it a go with the belt sander first if im not happy ill machine it
