I need some TB's for my Jenvey, Extrudabody and TWM TB's are crazy frickin' expensive for what they are, so I'm going the Motorcycle TB route. This is what came in the mail today, stuff looks real good (IMG:style_emoticons/default/piratenanner.gif) Attached image(s)

Question: is it better to have the injector nozzels High on the intake as with these TB's atop the intake runners or low nearer the port mouth like the OE intakes ?

QUOTE(rdauenhauer @ Feb 4 2014, 10:08 AM)  Question: is it better to have the injector nozzels High on the intake as with these TB's atop the intake runners or low nearer the port mouth like the OE intakes ? Always better to be close to the port. The atomized fuel has less of a chance to condense into droplets. It also provides better throttle response and low end performance. Think about driving a car with a tunnel ram intake. It takes time for the air to reach a good velocity so there is a huge lag. Not a problem if you are drag racing and dumping the clutch with a wide open throttle. Edit: This is still much better than the single plenum and long runners of the stock type 4. |
