Installed the a 51MM Throttle Body for Screamin' Eagle 103 today. The Dyno Tuner said the slight increase in Horse Power and Torque are easily felt before and after installation.

Here's the Dyno Results....

Exactly.  There have been several threads regarding whether or not to go with a bigger throttle body and the before/after comparison would be very helpful.

why the hell would you feel an increase in HP & TQ before AND after installation, that makes no sense too me, if thats the case save some money and keep the before

I should submit posts with greater skill than that, considering the members zeal for accuracy and content. My Bad.

What I attempted to share was the "DIFFERENCE" before and after the install. A slight gain in the overall feel of torque and power after installation of the Throttle Body. Is that better?

Yes, this mod was installed seperate and then dyno tuned. The link to my baseline dyno run is under the title "My First Dyno Tune".

I hope this answers the question. It did for me.

Sorry, still confused on effect of changing TB, did HP increase from 89 to 99 (or 102 on 5/27 dyno sheet) and TQ from 93 to 105 as a result of changing tp 50 mm TB?

I think if I am reading it correctly, it looks like the orginal dyno run was with a 50mm SE T/B at 105 tq. and 99 hp.  Then switched to a 51mm HP Inc. T/B and got the readings at the top?  Yes, no, maybe,  [smiley=nixweiss.gif]

[highlight]Yes[/highlight], sorry for the confusion. the data from 5/12/06 are the results before the Throttle Body was installed. As I look at it now, the horsepower gain of +2.92 and loss of -.14 of torque are due to the effects of the Horsepower Inc Throttle Body install, and of course the enviromental conditions.

The HP increase from 89.63 to 99.53 and TQ from 93.57 to 105.64 is from the baseline dyno tune ran 5/12/06 after the SERT was installed. The TB install gave me an increase of 2.92 HP and a fractional loss of Torque @ -.14.
