XKR Exhaust - Mina with and without crossover - is "screaming supercharger" normal?
My Jag is an 06 XKR Victory Edition. I installed a Mina exhaust (and pulley and air intake). The exhaust runs from the center silencer back. It has a nice sound, but still fairly quiet and reserved so I had a Magna-Flow crossover ($85) installed for a charge of $85.
I like the new sound - still quiet while cruising, but more pronounced around town and accelerating. Sounds more towards a refined V8 or V12 than a loud boy toy.
Question – is the “screaming” from the supercharger normal when under full acceleration?
Here is the vido of the sound: Start up, fast accelerate away, accelerating drive by and then a clip from my "echo chamber" in the freeway underpass. Two sets - first with just the Mina, then with the crossover.

I would also guess you are getting belt slippage on your new pulley under heavy boost. Try a new supercharger belt. I think there is also a belt and pulley TSB upgrade. If someone knows if the improved one was already fitted on a 2006 they can chime in.

Three things to consider. First, you have installed the Mina pulley upgrade so you are turning at a higher RPM. Next, and this has already been noted, it could be belt slip. Third, you may want to check the level of your SC oil and change it out while you are at it. I changed the oil in my 2005 XKR, SC recently and observed that it does run quieter at low and high RPM.
Nice exhaust sound but you are right the SC does seem to squeal too loud.

If I fitted your exhaust, that's probably all I would hear on my car! Hmmm, tempting....

Hi James. Love the sound you have achieved. I have the mina exhaust with straight pipes and get a popping sound which I hate. I would love to try the X pipe and was wondering where you had it installed. I am thinking we are neighbors as I see your NH tag and that looks like rt 142 in Franconia? I'm in Whitefield and spotted a similar car to yours leaving the Lions club car show. Not many xk8's up here so I'm thinking that was again you. I would love to find a local mechanic up on these cars and would appreciate any help. walt

With that car gone not sure what's next for the XKR I have now but finding a pipe bender shouldn't be hard, especially in NH where winter eats up exhaust systems like recycled beer cans. Keep in mind that part isn't expensive, it's the labor you're paying for: Magnaflow X Pipe

Would all these mods make our (I like saying this now! Lol) cars make at least 450hp with xpipes, exhaust, intake and pulley? Does any one have a realistic breakdown?

Nice exhaust note! I am definitely doing that Magnaflow x-pipe very soon, at least to start. It's got a very nice gurgle without being overtly obnoxious. I wouldn't even mind a little bit of modest popping.
Definitely sounds like belt squeal- mine whines but doesn't sound like a shrieking witch! Ack!
