Dyno Results.

[Guybuck]

I’ve done a stage 1 upgrade on my 2021 GT. It’s a DYNA Air Filter with plate and a TEC Stinger 2 into 1 exhaust. Has anyone ran a dyno on their rides with similar upgrades. Just wondering what kind of gains Ive achieved. I plan to run, on a dyno, at a rally this spring to get real numbers.

Will be interested to hear when you have results. Please post.

I wonder if the increase will be small but the power through the rev band might be more useful? I'm planning the same pipe but I'm not convinced on changing the air filter without more engine mods. I'd really like to see tests with Stock and Hi-flow filters on an otherwise stock bike.

There is always the butt dyno which seems to have a lot of credence on YouTube.

The trick with the filters (somewhere is a forum post where someone used a flow bench for this) is that the super high flow filters only pass maybe 5% more air than stock. It is the air box cover that gets you any real gains.
At $4 each, I have ordered a handful of spare air box covers for the J series and will be modifying and testing them to varying degrees once they hit the dealership.

Say, is that 6 pin plug under the side panel of the J-series a EuroV OBD connector? I happen to have an 'OBD2 to EuroV' adaptor cable sitting in a drawer that'll let me run a monitoring dongle which can approximate HP and torque figures in cars from measuring acceleration times between various speeds in different gears. Wonder if my cable will work for that... Do the twins have EuroV connectors for OBD as well? That might be an option for testing engine mods. The dongle was only like $10 from Amazon with a $5 app to make it do all the things. I think the cable cost as much as the rest of the rig, but don't recall because I was given it randomly long before I had anything EuroV and shortly before I got rid of my last OBD equipped car.

That’s impressive, and informative. Thanks for the share

I recently had a good read of the factory manual for my 2017 carbed Hima and was surprised to find a comment in it that " the ignition module was designed to reduce power over 5000 revs to reduce the possibility of damage to the Engine"!
If the INT have something similar these guys might have hit on something.
Wonder if there is a module some where from another bike which does not have this feature which would work on the Hima!

But would I do it would require a great deal of internal debate. I like my Interceptor running!

Now I'd like to ride something with a few mods. jayt1775 bought his with a few mods already done, including the pipe. But it is a slippery slope and as a lightie i always ended up regretting it. Change one thing, break something else and when it was a clutch spring or a bottom bearing I always cursed loudly.
