I installed one a season or two ago, and honestly I dont know what to believe. IMHO, someone would have to get IAT's of a gap ram air vs a cold air kit to verify any usefulness. Possibly the need for more fuel pressure to maintain a specific afr. I think it's just a cool novelty.

What ya got cooking, bud?!?!

Do you think you could have waited to disclose all that until he popped for the tune!! Come on, Rich!!!

Agree...luckily for the OP is that a 240 tune will increase power output without breaking the bank. And that the only thing that may be necessary, to take full advantage of the new found power is possibly a correction to max rpm.

IMHO...if you and your buddy are in a dead heat and he decides to install this contraption....you've already won!!

If everything is working as it should, and rpms are correct, what would you expect to change because of the 40hp increase? Just like any other sled you can always make improvements. IMHO, tune it and take it for a ride to see what's What.

One way to solve the increase in rpm (due to tune) is to change the drive belt to an Ultimax XS825 (yamaha only). This belt will offset the rpm increase, in most cases. Otherwise you'll need to move to adjustable clutch weights, like Dalton or similar.

Hopefully we can come to some consensus on a measurement. Very odd, two different instructions. Come on, Dave!! Lol

Here's the whole sheet I've had. It's pretty old and wanted to verify any changes with you guys.

Wow, glad I asked!! Wonder what this is???

Made a clamp guide to cut stock intake. Am I correct in assuming the cut line from bov inlet is 1.25"? Also, Redline1 claims the coolant hose clamp above intake has the ability to rub thru the top of Hurricane intake. There's zero gap, Definitely real tight. Surprised no one else noticed this...

Just trying to put everything into perspective and consider my options as I navigate this sport.

I have brand new 1.63 on a 1.25 track. Will the 1.63 be OK on a 1" lug track? If not would 1.5's be more appropriate? I had to ask...

Overlooked facts...ty

Cat axle w/drivers $385 Avid drivers & axle $580 What is it about the avid drivers vs stock that stands out, in respect to 1,000ft runs? And a few fly bys @ 130mph+/- Very slow by today's standards
