First time porting anything

Recommended Posts

Well i poped my cherry of spending hours grinding on the same piece of metal.

 

Cut the botton of the intake off to get access to bell out the runners. The casting on my intake pretty much is the suck. LOTS of casting flash everywhere. Just thought I would share. And I know I missed one of the runners, I left it that way for comparison.

Top of the intake. This area has a cover that bolts to it that houses the throttle body.

Well I am all finished up and here is what I ended up with. Of course I need to weld the bottom back on.

no dremel here. 3amp electric grinder with a variable speed controller. The grinder alone runs at 20,000 rpm but I have been running it at 8,000. I used 80 and 120 grit cartridge rolls. I could have used a longer mandrel to get way down in there but ehh.

 

Here are tools used

so you got the catridges from jegs i see... what they run.. and how big of a difference is that grinder from a dremel??

HUGE difference from a dremel. Dremel has got to be a 1 amp at most tool plus a dremel spins WAY too fast and has too small a collet. Dremel's use a 1/8" collet and all the decent porting tools use 1/4" collet. The catridge rolls are cheap that little kit was 32 dollars at Jegs. And better kits can be had for the same money if ordered of the net. I didn't feel like waiting so I went and picked this one up at jegs.

SVT said that the fix had been done, but there was no dot on the intake. The runners into the heads are smooth like an extrude honed intake, but the rest of it was HORIBLE. I have no clue what was going on.

 

I can tell you this, there was alot of material removed from this intake. After I finished i swept up half gallon of aluminum dust, and I'm sure there is still alot to clean up.

I bought the grinder for 49 at harbor freight with the extended warranty in case I burn it up, but I doubt I will since I have been running it at half or less than full speed.

 

The speed controller came from woodcraft in hilliard for 60 bux aprox.

 

I looked at other electric grinders with variable speed control built in and they were all 300-400 dollars.

Greg,

 

Looks great. Port and polishing is a pain in the ass.

I did a little on the double hump heads I put on my camaro.

Its one of the those things that starts out really cool, buy about half way done you wonder if it really makes that much of a difference. :)

 

Of course it does, but that doesnt make it any fun to do.

 

Anyways, good luck on your build up.
