Best air intake
Do you think getting the air out away from the motor helps with power?
I have not had my bike on a dyno as yet, however... after mounting this intake up and retuning with my TTS... I can run under 65 easy in 6th gear... I've cruised along at 60 up and down hills, with no problems. It "seems" to have increased my low end torque by a small amount. Won't really know for sure, until I put her on a dyno... but I'm not all anxious about it either... I'll probably wait till after I do a set of cams next year before I drop coin for a full on dyno run.
Nice Bike..

2009 Bonneville 6 PASSES 2 RECORDS 3000 M AF 145.018, 3000 MPS AF 148.426, TOP SPEED 149.811.
2010 CHEATED DEATH 2 TIMES! B U B SPEED TRIALS!
In 2010 after adding the Turbo in August at Bonneville made 2 Passes and aborted both runs at 150 to 170 mph (while entering the timed mile) after severe tank slappers, torque and horsepower were ripping the spokes out of the rear wheel rim.
As of today we do not have dyno sheets, although at 48 to 5,000 rpm (50-60% throttle) ( 8# boost spring) we were making over 180 hp, running about 190 mph during a brief dyno session. Seems we needed to tie the bike down a little better, the slightest amount of throttle and we were jumping off the dyno drum and flexing the front forks against the wheel stop.
After Bonneville changed the bars out and ride it as usual. Will roll to Monterey on Sat. and Ventura on Sun. this week end.
The 124" motor has rolled coast to coast with over 70,000 trouble free miles on the freeway, drag strip and the Salt Flats. The chassis has over 150,000 documented miles.
See it run on you tube 2 wheeler racing turbo harley.

Thanks,

Once an air cleaner can flow as much as the engine can draw it makes zero difference on the dyno. Only for engines with a big flow (stage-3, big CC kit, etc) will you see any advantage of an A/C with a bigger surface area than the majority of good aftermarket stage-1 ones.
The only other exception I can think of is if you have a reversion pulse from a poorly tuned exhaust causing a big stand-off of fuel/air at the carb/throttle-body mouth. Then a long intake is important.
Do a little more reading.. off forum..

I got roasted last time for my 'opinion' on intakes... so this will be all I say on the subject.... your welcome.

You rarely see a stand-off effect on lightly tuned stock bikes and you only get it on stage-1 bikes with crap exhausts. The symptoms are a fuel-soaked A/C filter element. If you take the A/C off you can sometimes actually see the column of air-fuel flying out the intake. You can fix it two ways: put a foot length of pipe on the intake (as they did in the article - hardly practical) or fix the exhaust.
