Thread: Which pulley should I try next?

Just finished my rocker swap yesterday. Mods are in my sig. Now with 1.9s, wondering which size pulley I should purchase and try next? Currently running a 3.3 with no knock.

I am thinking dropping to a 3.1? maybe a 3.0?

Let me know!

2.6 or bust

Somehow I knew that answer was coming haha

Gotta love that e85 for a knock killer. Didn't notice that in your sig at first and was like why no knock?? Then I saw the magical corn. I was able to drop .2 with 1.9.. So I would try the 3.1 first.. 3.0 is probably pushing it. but I'm no expert. But thats a pretty good guess I'd imagine. Gonna be at the edge of your limit with the stock pump and corn pretty soon as well

Haha, E85 is for sure awesome.. Race fuel for < $3/gal.. Freakin sweet!!

That's what I figured as well.. I'll order a 3.1 from ZZP today. Thanks for the input man!!

No problem! Hope thats no knock for ya is well! I went off corn for a bit because I am so bottle necked with the stock exhaust on my bonnie for now.. and its not much less than premium where I am now.. and I drive 30-50 Miles a day and got sick of the milage :P

Gotcha gotcha.. yeah, the mileage definitely takes some getting used to. definitely have to plan out my trips a bit more and make sure I have a backup plan!

I'll get a new pulley here soon and update this thread with how it went. Curious to see how it will feel after this rocker install and pulley drop

Wonder what kind of times it can do now???!!
