Thread: Porting with a dremel..?

you would probably need the entire afternoon to hog it out nicely.

if the blower gasket tears at all you cant reuse it, but if you get it off clean you should probably be okay.

but wait, thats a thing i never thought of...
with a ported blower. wouldn't you need to make the blower gasket bigger??

I use RTV instead of S/C gaskets. It costs less and won't blow out like a S/C gasket.

how in gods name did you blow out a blower gasket?



you also dont need to enlarge the blower gasket opening unless youre taking out the h-beam which you shouldnt be doing unless youre going intercooled.

also depends on the bits and how aggressively youre going at it. i would suggest you invest in some carbide bits.

My bench racecar has a lot of boost...

what type of bit did/do you use?


because i'm thinking of just buying a another blower with similar miles to my car just to make my life easy and make this a quick job, per say

i would suggest that, yes. that way you don't have to rush and you can make it nice.

yes.

imma genius.

i have heard people using a saws-all to open up the bottom of the V. i think this is what im gonna do when im done with the heads. cut out the notches and then clean it up with the dremal.

i use the following bits:

i have about 4 different sizes of the above round bit. they were invaluable to cut the area around the valves when i was porting the heads.

these work great on iron. but if you use them on aluminum or what ever the blower is made of, the bits will clog up. it is good to have a piece of iron or steal around so you can go back and forth and use the steal to clean out the bit.

another problem is that for long periods of time, the dremals will get very hot and you will need to let it cool down. so sitting there all day you may end up destroying the dremal. i would think your best bet would be to go to harbor frieght and pick up a cheap die grinder and using that. dremals arent cheap. so take care of it. if you are going to spend $80-100 to replace your dremal once done you might as well buy a case that is ported off ZZP or other site. esp if you need to buy bits too.

but if you have access to a saws-all or even a hack saw that you can flip the blade and run it backwards thru the V that can save time and will prob make a cleaner cut too. if your doing this method, i would put a towel in the case so you dont scratch the surface. and also tape the bearing area where the rotors go in. you dont want metal shavings in those bearings.

i took the notches out with my sawzall then used my drill with dremel bits to clean everything up. I did the inlet as well. I also bought some grinding stones from autozone 5 of them for $3.19.
