:Bob Endress from Vortech drove 6 hours roundtrip to bring me the part so we could deliver the boat as promised. That's customer service.[/QUOTE]

He probably just needed to get away from the Ol'lady

I run the Pro Charger it performs well but I will agree that all the fuel set-up and ECM were up to me and the tuner.I had a hard time getting any answers. Thanks to Arizona Speed and Marine. Sorted out injectors, ECM, etc.

So basically if I cant fit the vortech which it seems I cant the whipple has the best ease of use. The procharger as an item is as good or similar but has less then stellar ecu issues and may require more in depth tuning by someone who knows what they're doing as opposed to the whipple which from what I'm reading is pretty much plug and play so to speak. Am I getting the right read on this?
I asked around locally and nobody here seems to be able to even get the whipple for a 500 efi right now. Any truth to that?

Yes, I have heard that there is a shortage of Whipples right now...

So why doesn't the Vortech fit???

I am wondering if others find the Whipple blower whine, or shall I say scream, a bit too loud? Actually irritating...you cannot hear the exhaust at all. Maybe it has something to do with being only a few feet in front of the Harwood scoop. The engine (an HP500) does make good power though!!

I’m sure this is not what you want to hear but, seal off or remove the scoop. You probably don’t need the extra air anyway. My EFI quad rotor is completely under the sundeck and I barely hear it. Even with mufflers my exhaust is much louder.

Thank you for the reply, the idea of baffling the scoop had come up, guess it could just be removed and a new hatch made!
