Captain, that was for the supercharger only.  It does have a pulley already installed, but it is the same size as stock.  3" I think.  I didn't want the whole kit, since the KR already has the CAI.  I'm gonna send this one out to get polished along with a polished L&M high flow elbow and polished TB.  It should look sweet on my red car.

i'm finding several different part numbers for this upgrade kit. which one is a direct bolt on? m-6066-sgt or m-6066-svta, or m-6066-tvs? what's the difference? kr525 which one did you install?

m-6066-sgt = complete kit with tuner and CAI (for 2007-2009)
m-6066-msvta = complete kit with tuner and air inlet resonator eliminator (for 2010 and newer)

not sure what m-6066-tva is.

tvs without tuner and CAI was also available under parts number m-6066-tvs (76mm pulley) or m-6066-msvtt72 (72mm pulley).

The sgt has the bigger pulley. I don't think that the change in pulley size would require changing the belt. On my '07 GT500, I had a 2.6' pulley and kept the same belt, with a idler pulley. A 72mm pulley is larger than 2.6' (roughly 2,83') so I don't think a idler would be needed.

[08KR525]

I don't think belt slippage is an issue unless using a 2.65" or smaller, then I put a 90mm idler on it.

OK GUYS,  GOT THE TVS. NOW MY QUANDRY IS: SHOULD I RUN IT WITH THE KR TUNE AND SAVE THE PROCAL VOUCHER FOR LATER IF I EVER DECIDE TO CHANGE TO A SMALLER PULLEY. OR SHOULD I GET A PROCAL TUNE BECAUSE THE CAR LIVES AT 4300 FEET. DOES IT MATTER TO THE KR TUNE? ANYONE HAVE AN OPINION?

[oldlugs]

How about taking it to a dyno shop with the KR tune loaded, and just have them double check that it's not running too lean?

[terumi71]

There is no need to put the procal tune in and it definitely won't make any difference with your field elevation.

If you have the voucher, you might as well use it.  Ford will send you the procal handheld tuner to install the procal tune.  Menu driven and simple to install.  It will store your factory tune.

It's not a full blown handheld.  In fact very limited in its use.  For example, if you put bigger wheels on, it can handle that computer adjustment to keep your speedometer accurate.

You bought it, so you might as well use it.  Will it make a difference in performance?  No,  I ran both tunes after installing the tvs.  The throttle response felt a little more peppy (or it was in my mind) with the procal tune.    Dyno will show zero difference between procal and stock KR tune in peak hp.

I finally installed the procal tune simply because I needed the EO# here in CA for smog check to be 100% legal, as advised from ex CA smog inspectors here on this forum.  Otherwise, I wouldn't have done it.  Continued thanks to those past smog advisements.

[terumi71]

Also, going to a smaller pulley later with your tvs makes no difference on when you install the procal tune; ie, if you put the procal tune in tomorrow, and 6 months from now go to a smaller pulley, you won't be changing anything in the procal (or stock KR tune for that matter) tune.

I have the 2.72 pulley on my tvs.  For me...that is the smallest I would go.  I know others have gone smaller.  But that's as small as I would go.

[08krrick]

THANX GUYS! SOUNDS LIKE THE KR TUNE IS PRETTY VERSATILE IF WILL HANLDE A TVS EVEN WITH A SMALLER PULLEY. I'M IMPRESSED. TERUMI71, ANY DRIVABLITY ISSUES WITH THE SMALLER PULLEY? STILL SMOOTH AND CIVILIZED?

[08KR525]

I've got the same setup at Terumi1 (thanks Terumi1) and this is the way the KR should have been outfitted from Shelby in my opinion.  The car behaves the same until you get on it.  THEN HOLD ON!  It is a beast.  I can't even imagine what these guy's cars are like with the bigger KB's and Whipple's and all the other hardware.  I like the TVS because it still fits under the KRs strut brace.

I'm thinking about a KR for my TVS

[08KR525]

I like your thinking Lucky Snake!

Does anyone know what kind of power a KR with a TVS puts down?

I can only guess. Stock is around 460 to the wheels so my guess with the TVS would be 520 to the wheels.
