Nearly forgot to top up coolant afterwards :rolleyes:

I did mine on Friday night at DH's place. Yours looks good, good job. Haven't driven it yet, but it had been started up. Idles like a bit of a pig and sticks at about 1300 revs a little bit when maneuvering. at full throttle though should be a right old laugh :cool:
-
did you do the back? its quite bumpy there got loads off.
Carbide burr's slice ali like butter took seconds done quite a few of these now, does help to be The Engineering manager :grin:
-
Yeah back too. I used a hand file haha, took a while and gotta admit, idle is probably like it is due to the fact I got a bit too keen on some parts. If I had used a dremel then I would have had no probs at all.

Gives you an idea how much came out of the back :smiley:

Can't really see too well on those pics, but looks about the same as mine. Just like the inside of a bog roll, smooth with no humps :smiley:
-
prob took too much off around butterfly if idling wierd, mine idles just as before i smoothed mine but throttle response is much better esp. from low revs.

Yeah that is the problem. It's because I used a hand file rather than a dremel.
-
is there a sticky for how to do this?
- just found one!
-
dremel sanding drums + flap sanding drum things work best, there are threads on vortex aboot it
-
yeah found that vwvortex thread and looked like a nice easy job, is it true that you can hairline fracture the tb if you go at it too long because it gets hot?
-
poss but i doubt its easy to get it that hot, just dont use blunt/worn cutters/sanders for ages+ shouldnt get hot atall, i left the 4(ish) mm around butterfly so as not to affect idle but brought the humps+ sharp edges right down, havent bothered polishing it just left with a fine sanded finish for now

can someone post up the diy link?

Save yourself the agro and use carbide burr's to remove the material.
cuts like a knife through butter sh!t hot finish no heating of surface and no abrasive material everywhere to clean up/out of TB.
Takes less than a couple of minutes but a steady hand is required :smiley:

Is this actually called porting?
As i believe porting to be when u make the ports in the head bigger?
Isnt this a "flowed" tb?
Or am i barking up the wrong tree? lol

You are probably right, its a generic term used in error me thinks
By doing this you are improving the flow and increasing the area.
But when you enlarge and port a valve seat you are doing a similar action
I suppose the porting is the re shaping of the area around the valve seat
which improves the flow of pre and post combustion vapour/gas :undecided:
I use the term for matching gaskets and flanges removing webs improving lead ins/outs throttle bodies etc etc
In essence yeah you are right :smiley:

The Mikester is right! :shocked:

im never normally that pedantic, im ever so sorry! lol
