Considering going stage 3 with the upper pulley,but I not seen much input on the griptec pulley, I understand the theory about it ,but in real life is it noticeable, before I open my wallet ,I have stage 2 with transmission tune on a V6,

 

Yeah I have the same question honestly, not much actual data out there I can see.

There is enough data supporting EuroToys on XF posts, but not really on this setup with VAP and dual pulleys as published.

 

I have the added transmission tune that once you hit the gas your gone,but there's no data on the griptec pulley ,if some one has it let us no your experience with it

 

I was running VAP’s Stg2 for a while, then Stg2 + TCU tune, and now Stg3, TCU tune and their lightweight rotors. The upper pulley (to make it Stg3) and rotors were done at the same time so hard to say exactly the added benefit of adding just the upper, but I can tell you that the upper + rotors has made a huge difference in acceleration. I intend on doing some Dragy runs this weekend to compare and will share.

 

Great can't wait to see,what puller did you use,I have a few to try

 

The puller available on VAP’s site…about $60

 

I believe VAP only offers the installation tool for the supercharger pulley. I am also interested in knowing what puller people have used to remove the stock supercharger pulley. I just purchased the upper pulley to go from Stage 2 to Stage 3 and plan to do the install this winter.

 

I ordered one of these and plan to give it a go over the holidays:

 

After talking to Chris at VAP (thanks Chris!) - I ordered one of these (black Friday pricing might still be in effect, I paid $100 shipped):

https://www.ecstuning.com/b-schwaben...025746sch01kt/ Great pics of the tool on the site.

It is not perfect (it's for 3.0L supercharged Audi's) but it will work fine and unless you gorilla it the existing pulley will be undamaged. I looked at all kinds of other options at many sites, for an extra $40 it seems worth it (?) to not mangle things up. Sucks that I think I may never need to use this tool again, but hey I'm a guy, more tools is good. :-)

 

I did Stg2 in my garage, Stg3 went to shop…the upper sounded like a real PITA. I bought the tool and told them they could keep it if they knocked $50 off my bill. They were interested since they do a lot of VAP work.

 

Absolutely worth the money. I purchased my car with stg2 vap. Was not happy with performance. Got the upper pulley and was amazed at the diff. I also replaced a stg 2 tune that was installed in 2019 with a stg 3 tune done in 2023 so I don't know how much of a software improvement there was but I was very happy with the difference. Now I am stage 4 and tbh, I noticed more diff going from stg 2 to 3 than I do with e85.

 

Thanks Doc,oc for your input ,did you install it your self

 

Sure did. The right puller and an impact wrench makes for quick work.

 

Nice, I did the lower , now time for upper

 

Good luck! If you've got help, pulling the hood is very easy and will save you lots of frustration vs trying to work around it.

 

Thanks my friend, I also have The transmission tune that will be the icing on the cake, has anyone dynoed there car, with results other than velocityap we no there results
