Hard to believe you have seen 74 mph speedo or GPS in a PQ 280 with a 502, what mods have you done to get 500HP??? Is that Dyno prop numbers?

Chine walk, trim the drive down a click, your over trimming looking for that extra 1 MPH, and add a bit of tab/Kplane.

PQ is one of the dominating makers in our club, great boats overall. In fact we Rocked the Ches Bay today and the PQ's did great, the 340 is a very nice boat and does well in the bay. (we have three 2002 340's and a 2000 280 with a 502 in the HRPA)
$2700, a whipple would bring better results than the hull blue print, I personally am not sold on that whole theory. I know Fountain does it standard on all their boats.

Whipple or Pro Charger....I've been looking into both systems........I don't want to change the fuel injectors...The engine is a hp500 efi...I thought it was 500 hosepower....and the gps says 74 mph.....thanks....I'm not picking on PQ I like the boat....But if I'm going to go faster with a charger I would like the chime walk to go away....With a charger I understand I'll have to change the prop.........I can run the tabs down...That's not a problem......Thanks
