Anyone?

I have major cruise control effect going on due to too large hole drilled out.

TIA,
Daniel

 

75 mm i believe.

 

?????

 

I am talking about the hole in the blade itself sorry for not being more clear.

 

4 mm or .157 inches. 5/32 inch (.156) is very close.

The next larger 64th (11/64 or .172 in.) increases the area about 20%, so be careful! Increased area approximates increase in airflow.

Using number or wire gage size drills, the approx increase in area:

(4 mm or 5/32) .157 = 0%
#20 or .161 = +5%
#19 or .166 = +12%
#18 or .1695 = +15%
#17 or .173 = +21% (also 11/64)
#16 or .177 = +27%
#14 or .182 = +34%

3/16 or .188 = +43%

 

Thank you very much that was exactly what I needed. I saw it once before but couldn't find it in the search fnx on this board.

 

Depends on the year. All of that info that Old SStroker posted is right for 2000 and up TB's. The hole in the earlier models was a tad bigger, say .162

We both know this because it's been varified with pin gauges at the shop.
