On your, the top right looks a littly rough. I'd at least clean that up a bit while you still have the TB off.

take off the TPS sensor, take out the throttle blade... then tap the shaft on the TPS sensor side... this ring clips it in place... just keep tapping it and it comes out.

once you tap it out, its easy to cut the shaft...... a friend of mine in the local club has ported a few of them for club members and hes helping me do mine....

Yes, its a press fit, so beating it out with a BFH is how i got mine out... However, rather than cutting half the bar, why not gring it down a little thinner on both sides, but leaving some meat where the screw heads and threads are. You can getthat bar pretty thin.

you can leave the thread side of the bar alone, and cut the other side off.... thats much better then grinding it thin... for one, its smaller, but two, theres no thin bar to break and get sucked into the motor...

and the thread engagement is the same with the untouched backside bar......

I wouldnt worry about the bar breaking and getting sucked in. If anything I feel that the two thinned out bars would be stronger than a single bar of the same cross sectional area. reason being is that you save the ticker half of each side, and grind down the rest. plus you have a wider area which you can knifeedge and get really fancy that way theres a shallower angle to disrupt the wind... but this is all really far fetched. honestly, i really dont think anyone will see any difference between the two methods. My way will probably tack on hours to the process, while your way might add 5 minutes. If youre not gonna see anything for your efforts, why not take the easy way out.

the half-shaft mod was tested on 16# of boost, and it held up. the one full shaft is better then two thin ones, both for flow and integrity.

Looking good chris, maybe that car won't be all looks when it's time to hit the track again.

Who's going to do your cam install?

Pretty good job dude, not enough left that can be done to it to warrant taking it back apart but it is a little hard to see exact detail in pix. Car looks like it'l rip your head off and crap down your throat!

Thanks man, actually now that I have the center bar cut, i can see where there is a little bit more i could take out just in front of it, but like you said, its just not enough to really make any difference... However, when i take my stock one off my car, im gonna do it, and take my time. I know a few tricks now

Yeah man, once you get the skill level up to doin one right you get done with the first one and "see" room for improvement on the next one. There are certain ways you can port one to get what needs to be got and not take anything too far(like the concave casting on the bottom outside of the TB thats real thin were the "lip" is) and be consistent each time but that will come with practice like anything else.

What did you use to cover up the huge gaping holes for IAC? I didnt do that when I first ported mine and its going to be down for a day or two for the cam swap so I thought Id go back in and port a little more and do that as well. Did you just stick some pen shafts in there while you put in the filler or did you drill them out?
Thanks
