If my memory serves me correctly you did another change in throttle bodies. Didn't you have a ported, and polished stock TB on not long ago? What was your reason for switching to the AccuFab TB. From reading your posts, I see that you do a lot of research before you ever make a mod. I'm just curious as to what provoked this change...

 

I am just trying out an accufab. I was told it would probably not help, maybe even hurt, over the ported stock unit, but I want to try it anyway...

I'll sell the one that I like least...

I am in for a Jan 18 dyno session with the Halo Group in Houston and will try to do some back to backs with a few of my duplicate mods...

It will probably turn out to be a waste of time and money, but an interesting experiment none the less.

Kewl! I thought maybe you decided the AccuFab would net a bit more top end. Let me know what you decide. I may be interested in the modified stock unit, if it becomes available.

Where are y'all doing the dyno runs at? I may try to come by just to check it out. I probably shouldn't though. I have been able to avoid the engine mod bug so far...

 

Ok.. what does "ported" or "polished" mean? What's the difference between a stocker?

 

Jan 18, Halo is hosting Sal from PSP for a couple days of dyno work. If he has the Harley software by then, I will buy an autlogic to go with my Diablo and Superchip -- that way I'll have the full set

Unfortunately, the timeslots are now all filled up... However... You certainly could come check it out. Email me and I will get you the address as I don't know where it is (Just that it is Sat, the 18th...

As far as the ported/polished, go look at these pics and see the difference. Paul at razors edge did my TB and this is how it came out. The goal is to smooth the flow so that you can produce more airflow with less turbulence. Porting is the wrong word to use here because porting generally carries the meaning of making it larger, which is not totally the case. I noticed *crisp* throttle response with my newly worked TB and Upper plenum.

The thinking is that the ported TB will give better low to mid performance over stock and that the accufab will give better performance mid to high end. I wanted to try an accufab to see if it helps my 1/4 times since I seem to run out of truck after the 1/8th. I hope the cat back opened things up enough that an accufab can breathe a *little* more in the mid to high end. I just hope it doesn't slow me down in the 60' or the 1/8th...

I will sell my ported TB for $150 firm if I decide the accufab is better, but I have been told by several that it actually might hurt my short times and help my long times, thereby netting nothing but a $500 hole in my pocket. Nothing ventured, nothing gained...

that has the stock TB, ported TB, stock plenum, and ported plenum.
