Who's used the nitrous kit?

[Tj-hooker]

Yuck it's a fart can no thanks I under stand that the back pressure within the expansion chamber created by the convergent and divergent areas of the exhaust following up by good old Bernoulli law but it's just **** <~~~ Ugly haha! I like em on dirt bikes but on a little engine about the size of our heads no I'm good but at the end of the day its not about the power its about the thrill . The joy get when that silly old whip cream cylinder gets engineered on and you hit that nos shhhhh blast off...!!! Hah love yours , you only love once . Don't stop the creativity
There are guys out there at bashes on motorbikes already so why not "give the something to talk about"lol respect power to the people stick it to the man

Electric blowers - it is all about pressure. You need a blower that can maintain at least 1 psi above atmospheric while filling your engine. Most cannot even do that while dead-headed. 3psi would be a more practical range for serious power. The turbo on my SVO builds 15psi stock.

Nitrous - the first nitrous kit I ever installed in a V8 did 3 runs before blowing the steel headgasket out and splatting all the coolant over the track. Another kit in a HO Mustang would slip the clutch if applied under 5000 rpm and after one bottle stripped the casehardening off the transmission gear teeth. It is harsh stuff. I am planning to use nitrous on my turbo SVO in a 1-2 sec shot to eliminate turbo lag. I've seen it used on sleds. Mostly broken sleds. Tricky stuff nitrous.

Boost bottles - My DT200 came with a boost bottle from Yamaha, as did many Yamahas, Kawis and other 2 strokes in the 1970s and 80s. Yamaha called it the YEIS system:

Notice the big diameter connecting hose and short hose length.
As KC mentioned, many of the aftermarket boost bottles don't have those features and are a scam.
I did a test using vinyl tubing as a variable volume boost bottle:

It works, but needs to be tuned to the rpm you want to run at.
This was a test only, to prove the concept. I feel simple is more important than a fractional gain.
And I agree with KC, more power to be found in a pipe.
