No oil cooler and only 4.5 qt. oil capacity on a 6.2L MPI.

It took 5.7 qts last oil change!

Well thats nice of them when they have sold 1000s with 425hp in the form of the 496ho

Jeff do you recall if your H2X had any model specific parts on it to make it work right. I know the 6.2 motor already has forged parts stock so thats a plus in my corner. I see yours had an MSD ignition of some sort and I see the exhaust was upgraded. Would you happen to know what spark plugs were in it? I was planning to leave mine stock except for the needed upgrades to make it reliable.

Knot, if your saying an oil cooler would help I don't see it being to difficult to retro fit one dirrectly off the steal oil filter lines to a small oil cooler. I could even throw a little 12v fan to cool the oil cooler.

My bad. You are correct that the early 6.2's took 5.5qts.

Contact Bob Llyod at Full Throttle Marine. He has experience with adding superchargers to 6.2's. Good guy and very knowledgeable. www.fullthrottlemarine.com

No. The B1 is rated for 400 and was sold with the 496MAG and now the 8,2MAG, not the HO. That is the B1X rated for 450 hp. Before that, yes the B1 was sold with the 502, but I'd think the gears was better quality back then as is the case with the XR junk gears now.

I looked the Full throttle web page and the Whipple setup looks alot nicer then the procharger. They have kits for 02-05' so I hope I can make it work on my 01' I am gonna give bob a call today I will post the info when I get it.

Hi Razor i have twin 496ho in my boat ,how can i tell if i have the B1x or just the B1 Thanks in advance .
