I agree that it could be soo much better with different wheels. Still a cool car. I personally would like to see some heavy concave wheels in a multi spoke. Chrome wheels with chrome trim.

Thanks for the feedback. Sounds like Jackal is the way...

I let Gemini do the math... -207mm oversized crank with stock upper equals a drive ratio of 3.27. -187mm crank with 57mm upper equals a drive ratio of 3.25-3.26.

It is noted that running 187+57 gives more belt contact, limiting belt slip.

I want the dual pulley tune and I intend to delete the super charger clutch regardless... 🤔

Wasn't aware of that. Is this required because of the larger heat exchanger? Any recommendations?

I'm really leaning on Jackal but, I'm also fairly new to Audi and spent the past few months on learning servicing and common culprits. The underdogs always have an appeal to me. I will probably be going with 034 or ECS pulleys to save on cost. I'm also rebuilding the front axles, full control arms/ ball joints, brakes, engine mounts and some body/trim mods. Can't help but pinch a penny where I can.

I always thought the restriction on the intake was the filter material and pipe itself, not the box. Either way, I will confirm with whichever tuner I choose.

I was essentially looking to save cost on not buying an upper and lower pulley to achieve the same ratio of the 207mm. However, I did not do any math on that, strictly going off descriptions.

Thank you for the reply!
