A couple 575 sci questions
I originally had wanted to add a chiller and a bigger blower to my Howard but it won't fit, and I'm not willing to cut up my seat and hatch. So, I am just going to enjoy it like it is except for a tune. The engine is stock but I suspect the blower pulley is a smaller one than original based on a conversation with the last owner.
1. What is the stock pulley size on a 2004 575sci?
2. Who has a good "canned" tune for the engine.
Thanks

4" is stock, I ran 3.5" with stock tune. Have you looked at the Dyers kit? A 671 or 871 would be a huge upgrade over that 250 and I believe they run a 2" wide belt vs the standard 3" Gilmer belt. You will gain a lot of performance just with the bigger blower and leaving the chiller out. How much clearance do you have?
I would think Eddie Young, Ben Wiersum or Mark Boos would have a tune, this is actually a necessity as the stock tunes wash the cylinders down at idle...way too rich.
