SA says theirs doesn't.

Does this one?

should work, but if that doesn't work, go to http://www.eastwoodcompany.com/ and search porting


Any others?

Haven't looked at dremel tools; are there comparable bits made for dremel?

I don't have air, so I need to use my dremel.

Thanks

 

SA and the porting bits on Eastwood are all 1/4" shaft/mandrel. Dremels are typically 1/8" or 3/32" collet - too small.

Some of the bits and the like are available in Dremel size. But, Dremel makes things for small, precise work rather than the virtual "hogging" you have to do in porting. Polishing those large surfaces would also be a challenge. SA does talk about electric driven motors, but don't really endorse their use.

For the cost of a good electric system, you could probably get an air compressor (especially used) and diegrinder to do the job. You'll also have an air compressor to use for other things after that.

Maybe you can rent the air driven stuff, too. It's gotta be a lot cheaper than buying it outright

I've gotta a dremel here, as well, and was disappointed to find it won't work either.

 

I used an air driven die grinder to initially port my heads, but to port match my heads and manifold, I used my dremel. You don't need a specific kit. Dremel, and other companies make many different bits that you can use.

Your Dremel will have it's tongue hangin' out by the time you finish the first port! They just don't have the "Wheaties" to get the job done. Air powered die grinder is the only way to fly, IMHO.

 

If you do use a dremel, you might wanna pick up a couple extra sets of motor brushes. Those things wear out quick under heavy use. Ive already replaced mine twice.

Just to give you an idea of how much a Dremel sucks at porting heads, I can tell you that I've tried it.

I used the different stones that you can buy for the Dremel. I got ONE port done, and the stones were about half the size they were when I started.

Plus it took forever!!! And I was only pocket porting. It worked well for removing the casting ridges in the runners and around the edges of the openings, but I'm now going to wait until I get a die grinder.

Sorry, I should have specified--I will only be porting the tpi plenum, runners (maybe siamesing), and base right now. I'll be going out of town and won't have time to do my exhaust, tpi port, and tpi polish and also do the heads. Why am I doing the tpi and not actally getting performance by doing the heads? Because I only have a dremel right now.

Dremels are only good for engraving your initials into tools, or cutting off a bolt head when you don't feel like firing up the compressor

Actually, there are heavy-duty electric die grinders.. Du-more is a name that comes to mind. They're big $$ though, and much larger than a dremel.

I agree with the previous recommendations about getting a small compressor and running an air die grinder. Once you have a compressor, you'll never know how you lived without it!

 

Well if the stuff you're gonna do is aluminum, then a Dremel will work fine.

But you gotta know that with aluminum, you don't want the finish to be "baby butt" smooth. I forget the reason now. But I know that SA even tells you to use the 400 grit roll on aluminum, but not the 800. I think the fuel will condensate up, then run together into a pool, then drip into the runners. Something like that. I can't remember exactly.

No, that's not because of the aluminum, that's for wet intake systems. As in carb or TBI.

TPI is a dry system, so at least until you get to the port in the heads, mirror smooth is good.
