Those numbers would be sick to have...

There is a 115mm pulley but when I tried to purchase it ESS wouldn’t sell it to me.

These pulleys are not at all that special.
There are other sources. Vortech and Pulleyboys.com comes to mind.

That's strange, why didn't they?
Was it a matter of not buying their upgrade as a whole?

My guess is the numbers will be less than stellar. This platform NA or FI seems to do poorly in the 1/4.

I would guess mid 13s if you launch and row correctly.

So I just looked back in the emails and they said that Vortech doesn't make their pulleys, they do, and it is all custom offset. I also already have the 115mm on my kit, but they have a 110mm that they wouldn't sell me because "you need meth injection or 93AKI to run this safely".

They don't want to be reliable for an engine blowing then you sue them.

If anyone has a spare pulley, any size, if you send it to me or I buy it from you, I will have my machinist make the pulley in any size you want. Just need a pulley for measurements and their 'custom offset'.

Their 'custom offset' might just be a machined vortech pulley. I'll get a Vortech pulley and check and compare.

Here is the Vortech pulley. It looks like they machined the mounting nose shorter for their custom offset.

Interesting how the numbers line up.
5.00" = 127mm
4.75" = 120.65mm
4.50" = 114.3mm
4.25" = 108mm

Just got the newest AA tune on my N51.

Wow, is all I can say. Power from 1.5k all the way thru redline.

I've driven the f30s and it feels very similar to the power band of an N20 without the initial lag.

Very appropriate and responsible throttle control, my N51 doesn't feel like it's having trouble finding the right gear, and honestly the new amount of torque is eating my tires lol.

I got this tune with 5k on a new N51 engine and 54k body (sulev warranty).

Definitely worth the money Imo, next step is either headers or PE.

Also wanted to add I have had 1-2k miles with the tune so far and it has settled nicely
