Well, I actually got the guts to do this mod and am both very happy and very sad. First of all, I took off the entire throttle body and started to work on it. First off, I used an entire can of throttle body cleaner to get all the carbon/crap gunk off of the inside and the butterfly. I read in previous posts about how you might not want to remove the top part of the post so I didn't for safety's sake. I used a saw on the bottom of the top part of post where the funnel-slide to the MAF begins and cut straight across. I then made two angled cuts near the bottom of the shaft to remove one big chunk of metal. In comes the dremel and lots of work. I ground down the bottom stump to nearly flat and polished it down all nice and smooth as much as possible and rounded the bottom of the remaining top part of the MAF housing. This takes a while so be patient when doing it. Next, I used a round bit to port out the hole (air flows to the MAF sensor through this) some so more air could reach it, turned out nicely. Next came the wire brush attachment and the polishing of the entire interior of the throttle body. It looks great and shiny like a polished Edelbrock intake and is ready to be put back in. REMEMBERED TO COMPLETELY REMOVE MAF METERING PLATE! Placed butterfly back into place and screwed down tight. Ran lots of warm water through to completely clean out the metal dust and crap inside and used towel and q-tips to completely dry it out. Put both sensors back into place and voila, throttle body was ported, polished, and cleaned and ready to be put back in. Now, I drove around for an hour or so and found 1 place nearby that had a new gasket for it. So, I go back home with the gasket, use some more throttle body cleaner on the opening into the upper intake manifold, and clean off the old crusty gasket. I place the new gasket into place, push throttle body back into place, but bolts back on and intake and sensors back into place, and I'm done! Now for the bad stuff:
1. Forgot to tighten all throttle body bolts, so pressure built up and blew lower part of gasket out letting ALL my antifreeze out through hole. :mad:
2. Car drove fine for about 5 min before coolant ran out (all over engine of course) and I literally watched the temp gauge go up to 235 before I got the car pulled over and stopped. Talk about steaming from the antifreeze on the hot engine! Had to refill antifreeze three times to get car home.
Before the leaking problem and heating up, the car ran like a charm (after throttle body cleaner burned out initially) With the MAF screen removed, the bottom post completely gone, and the polished surfaces, the car gained more mid range power and definately gained a SOTP gain. 60 seemed to come a bit quicker than before, but no numbers of proof yet. As for now, car is out of order until I can order another gasket, get some gasket sealer to bond seal the throttle body completely, and of course remove and clean out the entire thing beforehand AGAIN, but when all the crap work is done with, I think I will be really pleased with the result. So, if you can withstand the time it takes to do it right and the possible gasket nightmare I had, this is definately a worthwhile mod. After I clean everything out again, hook it all back up, and get a good seal and a new gasket and get it running with some antifreeze :D I will let you all know how much better it is really.
