I bought the 496 mag and spent $4000 between Whipple re-programming my ECM and a 5 psi procharger kit. Now I am at about 600hp and still with less money than the HO. Go with the mag and Supercharge it.

did you do the whipple yourself?

I sent the 555 ecm to Whipple and the Procharger I did myself.

OK I was looking at whiples chargers they want like $6,600 for the kit itself maybe I'll look 4 a used kit

I would definatly go Whipple. I just got a too good of deal on a used 496 Procharger Kit. Just ask around there has to be a better deal that $6600 for the Whipple kit. What size type of boat are you looking at???

I'm looking at a new/ left over 2002 PQ 28

I live in OKC,OK these engines are produced in stillwater,OK 50 miles down the road. My good friend works at the mercusier plant he said the difference in cost to build between the MAG and the HO is $300 bucks at the factory. Cya

But I bet it costs them considerably more to buy the HO motor from GM. Then again, GM is only charging the big premium because they know Merc will.

can you say HUGE profit, HUGE rip-off
