since the last thing i read was porting the lower intake manifold is moderately hard to do since there isnt much working room or material, would there be any marginal benefit from just polishing it up? i do have port n polished heads so i was kind of wondering about port matching?

what do you guys recommend? also, whats generally used for polishing consumables? i assume most use a dremel and some buffing wheel after its smoothed by a grinding stone? any special clays or something?

 

If you can get it jet-hot coated as well, you should see less heatsoak and quicker drop in IAT2.

 

can you elaborate more on that? ive never heard of it.

 

Porting and polishing has it's benefits, you should find a local shop that has a flow bench and do it up right.
A Home "Port" will still work wonders, just go slow and blend things smoothly...

You can also check with any local powder coaters in your area as most of them do ceremic coatings as well.

 

Ceramic coating isn't really a good idea it will keep heat in, one would want the intake air cooler not hotter, same goes for chroming however to a lesser degree.

 

I had my egr tube ceramic coated and all I can say is it now stays cooler to the touch when the engine is HOT and seems to cool much quicker than before. No actual temps taken to prove my theory though.

I like the looks of that CC intake! Might have to do mine this winter. I should have done it when the SC was swapped and IC cleaned last winter!

 

It would be cooler to touch . it is containing the heat. this is why headers get coated, for increased heat scavenging. Ceramics will either contain or repel heat.

 

Makes sence, G! BTW, did you ever get your lower polished as you had planned?

 

Not as of yet,, need some spare $$ first.

 

as for polishing, any tips? i think the general consensus is to take it out to have it done (but moneys an issue now) or do minimal porting and make it blend well?
