Quest for mpg

We just did a run from NJ to WA. Horrible wind for almost half of the 3000 miles. I tried everything to get the best mpg and at times it was impossible to get more than 5.5 mpg. Ultimately the best cruising place was 64mph@1510 rpm and we ended the trip on 7.1 mpg average. I really feel the D12 likes the higher rpm. So try that. Unfortunately there are a lot of d12's that have been spec'd with 3.42 rears which really drag the mpg down. The best rear for the d12 is 3.55 or 3.58, if you have anything else your fighting the battle handicapped.

Cheapest mods are block the egr cross over pipe, cut out the restrictor plate and get a full flow muffler.

 

Where can I get the flow flow muffler from, sounds interesting.

 

Bloody iPad keeps trying to insert words or change the spelling. Typo corrected.

 

LOL

you watch motogp?

 

when I can ...plus the Le Mans series, also big on F1. Cheer for Lotus as I have a 77 Lotus at home. Wrenching on it during my home time is my man theorpy. Beer in hot tub is my relaxation

 

Pretty sure, but maybe wrong, when at speed the EPG does not restrict the exhaust flow until you engage it. Personally I would not want to be running around without an engine/exhaust brake. Also your engine warm up time will increase as the EPG closes some during a cold start to aid getting to operating temps faster.

 

Thought u mite be cheering for Cal Crutchlow, on that satellite Yamaha.
