Under better conditions than last time out, I just ran a new pb of 13.502 @ 101.31mph with a 60' of 1.947.

Not bad for a heavy assed Harley that weighs in at 5600lb

Mods are Traction Bars (LFP) 6lb lower pulley, shift kit, CAI and a Troyer tuned Xcal2.
When this truck was stock, it ran a best of 14.98 so that's about a second and a half off base times.

Thanks to everyone at TP.

 

Very nice, sweet truck.

5600 pounds? I thought my 2005 screw was about 5600 pounds, so is mine probably heavier than that even?

Oh, how much was the shift kit (and what is average installation cost?) and what did you gain from it?

 

13.5 is hauling tail...it's not easy to shave 1 1/2 seconds off your time...good job...

 

That's what it weighed on the scales at Houston Raceway with me in it.
I have since added the traction bars so it's probably fractionally heavier than that. All that leather and bling comes at a price

The shift kit was approx $40 at the time last year although you should check with TP for current pricing.
I did the installation myself as the kit comes with foolproof instructions and is pretty easy (if messy) to do.
You do need an In/Lb torque wrench for reinstalling the valvebody though.
Under normal driving, you cannot tell the difference between the new mod and the original shifting.
Under WOT, the box shifts instantly and will chirp the tyres between shifts.

Excellent for the strip

 

Nice time Adam. It looks like it's time for a Efan and a ported blower.
I think I would have opted for the FTVB.

 

Yep, probably efans next. To get the ported blower, I'd have to ship a core back to the USA which would be cost prohibitive given the gains I would probably get.

I had a long chat with MT about the Valve body mod Vs an actual FTVB.
He assured me that what I have done will have the same results but at less than a quarter of the price.
To be honest, I've never seen what goes into some of these FTVB's.
You could take one out of a used box, clean it up, fit a line mod valve and voila, an FTVB (although I know that's a name used by Greg)
If the box lasts forever, then fine. If it blows, I might have some new opinions but it seems fine to me.
All I can say is that I've trusted MT on my tuning issues so far and the truck runs really strong.
13.5 is (IMO) pretty good going for the HD and it's way ahead of stock Lightnings at the strips over here.

 

congrats on the new times. gotta love mikes tuning. i also have the line valve mod in my trans from mike.

 

That’s a quick time, 13.5

 

My FTVB is from Mike. And it's been in for 3 yrs with no issues. I can chirp 2nd to 3rd no problem.

 

Hi EnglishAdam & EVO,

Congrats on your new best time!

Regarding the FTVB's, we no longer advise them for a couple of reasons - first, we have seen some problems with them, coming in with rusty springs, etc - other had reported those same problems years ago when obtaining them either directly or form some other suppliers, but at that time we were not having any such issue - well, over time that has changed, unfortunately. Also, there is basically no communication with "Factory Tech" and hasn't been for quite some time now - that and some other things we do not like have led us to dropping the FTVB parts specifically, though we may still take another look at their diesel monster boxes whenever they start building those again, as we have not had any problems with them.

The bottom line is, there are several ways to effect quicker filling of the oncoming clutches - a properly designed shift kit, or our LMV, which is a nice & easy and very affordable fix that hundreds upon hundreds of our Lightning & Harley customers have been using for years with no issues, including in my own 11-second Lightning for 4 years. It does, however, require proper transmission calibration in the PCM - done correctly, the end result is a tranny that shifts nice & smooth under light throttle, but gets firmer and firmer as you give it more & more throttle, just as it should - so you get tire-chirping WOT upshifts and much better performance.
