Mach 1 Ported Throttle Body - 2003-04 Mach 1 Registry Owners Club

Deftones · 09-30-2010, 12:46 PM

I recently sent a stock Throttle Body I bought for cheap to a gentleman on eBay that I have dealt with in the past. He charged me $63.00 shipped to port it. He does an awesome job. I will install it once I get my JLT RAI in. Pics dont do the product justice.

Cool! Lettuce know how it works out for you. Dyno #s would be even cooler.

looks great...

DOCHMACH1 · 09-30-2010, 06:47 PM

Did he by any chance increase the diameter of the butterflies? It doesn't look like it. Looks good tho, hook me up with this guy through a pm if possible.

Looks like he cut the screw threads on the butterflies.

Hope they dont come loose !

I did this, but not so extreme when i was playing with mine. I just wanted to clean mine up/smooth it out. Ive contemplated going a little more aggressive but since it was my only TB, i decided i would Leave it be.

-really is no point to go crazy on it since the Butterflies are still whatever MM they came stock. It may be possible if you had a way of Honing out the TB evenly on both sides..would be a really fun project if i had an extra.
-The screws are actually crimped on one end to keep them from coming loose, cutting them off is necessary. little thread lock will keep them settled down.

Found my picture

I can do the same thing cheaper if someone is willing

I'd really like to see some dyno results. Might be another intake spacer type mod.

agreed would to know how it is after you get it installed. i had a friend bout a year ago ask me if he could port out my TB, i didn't know if i should or not and also never seen his work, but he did his own.

prob works better than the aftermarket ones everyone seems to have trouble with

na svt · 10-01-2010, 03:32 PM

Looks good but expect a 0 rwhp gain. Seeing how an accufab TB add 2-3rwhp to a bolt on combo the possibility of a ported stocker adding power is very slim.

Vndcatr · 10-01-2010, 04:04 PM

This is a big thing for LS1 fbodys .. guys would pick up between 5-10 rwhp on just porting the throttle body.. I had one in my cammed ws6

Definally something to do for the people who dont want the headache of an aftermarket TB ..

Looks good. I did this and figured it couldn't hurt. But I did get the dreaded hanging idle, which was fixed by putting in an IAC restrictor plate.
