Hey guys, I'm about to start porting my exhaust ports but the angle is a little odd. I'm using a dewalt die grinder and a dremel. Are there any good tips you could share with me? The dewalt is too long to fit in the housing and the dremel isn't as powerful but it fits. Also one more question. I'm using the racing beat template. Should I end the port where the template ends and then bevel in an angle or have the entire port with angle included, finish at the scribed line.

 

I use just a generic air die grinder, I'll usually come in the back of the port to get rid of most of the material, then come in from the sides to finish up

 

If you can afford to get another... one of the right angle die grinders would fit your needs.

 

If your DeWalt die grinder is anything like my Jepson (and I think they are since I remember seeing a stack of DeWalt grinders a while ago) then your best bet will be to do most of your porting from the OUTSIDE of the housing. This means through the exhuast port, and also at an angle from the side (working on the inside of the port...if that makes any sense). I've done plenty of porting with the tool, and it just takes some practice to get the angles down. BRIGHT lighting is also important.

Don't try to chew through the aluminium quickly as it will just clog the bit.

 

ok so you come at it from the outside? Through the exhaust sleeve or do you remove the sleeve?

 

Through the sleeve, that'll help get most of the meat out of the way (also helps since if it jumps it ain't going to hit nothing else), then go at it from the angles on the outside to finish it up.

 

oh yeah, one more question. One of the housings is shot so I'm practicing on it. My question is, Would you replace just one housing with a new one? I know that compression may be sacrificed on the used housing but will it be negligible? I can technically afford to replace both housings but it will be very tight financially. God damn mortgage. 2100.00 a month sure would buy a lot of parts lol.
