Hey Kurt, I'm kinda new here, I have a Mystique also, I read alot of your posts, just trying to learn some things, I'm just wondering why if your looking to change your blowers, and you have whipple intercoolers, why wouldn't you have a whipple s/c as one of the options for a blower?? and the reason i ask is that I'm thinking about putting whipples on my boat, just wondering if you guys heard of problems with them...sorry for the Questions just trying to learn as much as I can....thanks Joe

Hi Joe, The deciding factor is the almighty dollar!:drink: I can upgrade to a pair of TBS billet blowers for half of what it would cost for a pair of Whipples. As mentioned, I'm not looking for more power, just want it as reliable as possible.

Do the 250 blower shop blowers fit right on the 575,s or are there modifications that have to be done as well as tuning.

According to Eric @ TBS, they custom drill their 250 blower case to match the 575 mounting pattern and modify the intake for the 575 throttle bodies.

You have to send them your existing 575 blower snout and coupler as they do not make their own for this application at this time.

I think this is the route I'm going to go.

I have a BS250 on top of my 575 from the blower shop. They had rebuilt the stock blower once and then it blew big time. Unsalvageable. Biggus is right. They drill their 250 to fit the pattern and cobble together a new snout out of the original parts. Works fine for the last year.

Do you have any pics? if so, please send them to [email protected] I'd really like to see how it looks!

Thanks,

Kurt

Sorry, I don't until I get back to the boat storage in a month.

No problem. Did you see any gains or changes in how it ran with the TBS 250?

Did not notice any gain or loss. A little quieter whine is all. My 250 is polished as opposed to the blue. If I did it over I personally would probably have it anodized blue to match like the original. Still uses the narrow belt. Appears to be slightly smaller in length front to back
Mine was drilled to mount on a whipple low profile intake/cooler. Still have the original intake if anyone needs a manifold that is not going to run a cooler
