H2 Daddy: Thanks for the kind words! Like I've said in other posts, though, the guys who I bought H2's for earned them... :-)

OK, question for all you Whipple owners out there. Upon reviewing the instructions for "installing" the ExtremeFlow mods for the air intake, it appears that we've got to butch up some of the existing intake tubes, box and trim the inner well some. Not too hairy, but I'd planned on trading in my H2 when my SUT comes in, so I'm looking for a better intake solution. Who makes air intake systems suitable for the Whipplecharged H2? Please, no bashing each other, just info needed on a first rate system. I'm less interested in price that quality & performance.

Also, Whipplecharged: Where can one obtain info on the intercooler. It is applicable for "retrofitting" existing Whipple installations? From my previous experience with intercooled turbo-diesels (F-250 and 2 H1's), the flash programming & exhaust stuff added some HP, but the "seat of the pants" torque and gas mileage came after intercooling. Adding an intercooler to my stroked H1 with "Heavy Hummer turbos" (yes, two), I picked up almost 5 MPG!! I had always noticed in my non-intercooled travels that I got MUCH better MPG while motoring through the mountain passes in CO than I did in the (relatively) flat lands of the Texas Hill Country... Of course, diesels are much less sensitive to weight/load... :-) Wish there was a diesel option for the H2... :-\

2slo4now: Can you email me your ecommerce link. My email address is in my profile. Thanks.

Thanks for your input guys! BTW, my initial findings on my individual H2 is that the ExtremeFlow muffler ALONE is resulting a barely perceptible HP increase and about 1/2 MPG increase with everything else stock. I'll burn 3 or 4 more tanks of gas in a short trip over the next few days, so I'll have a more accurate measure by this weekend, when I plan to do the flash programming. If I can find someone to sell me a QUALITY air intake and get it FedEx-ed, I'll put in in on Saturday before leaving for a 2,000 mile trip through CO on Sunday.
