[@cedriclynch]

The newton meter can make power calculations easier. If you have the torque in newron meters and speed in radians per second you just have to multiply them together to get the power in watts. To convert rotational speed from rpm to radians per second, multiply by pi and divide by 30 (or if you only need an approximate figure, just divide by 10). I suspect that most car and motorcycle enthusiasts will never accept tachometers that read in radians per second.

[@marco23p]

The factor pi/30 comes from: From rpm to rotations per second: division by 60 From rotations to radians: multiply by 2*pi Just as some extra background information :)

[@joshuagibson2520]

[@goosenotmaverick1156]

For sure! I spent 2 years driving a 62hp, NA diesel pickup truck with a 5sp manual. I got to 84mph downhill once. 70-72 on flat ground was doable but took a while. I think the diesel insight is faster than it lol

He said he drove the Miata like a daily driver and the C7 very rarely got much for miles on it over the handful of years he was coming into the dealership with his NC.

[@tristan6509]

​@@robotcantina8957btw jim there's actually an engine made by kubota that has an electronic controlled rack like you're trying to make which is the D902k, a variant of the D905 which is a 900cc version of your D722. You can probably use parts off of that, though 3d printing is more fun

[@Clearanceman2]

It is pretty interesting how you show us slowly how difficult engineering really is. The Insight was designed fairly well all things considered. Especially for when it came out.

[@robotcantina8957]

Indeed, the original insight was a very well thought out car. My only issues is the gear ratios in the transmission. Seems like a lot of other folks don't like the ratios and there are a few mods that can be done to make the car more drivable.

[@IstasPumaNevada]

First-gen Insight was designed with efficiency as a priority, which sacrificed most other things like cargo weight limit, number of seats, acceleration, doo-dads, etc. It was still available with air conditioning. :) The car was basically Honda's test-bed for new hybrid and efficiency technologies, so they threw everything at the wall to see what would stick. It's worth noting I've never had trouble getting up to speed on a highway on-ramp in mine.

[@ryandavis4863]

[@aaronschocke2147]

[@Texassince1836]

Boost vs air volume are 2 different subjects. You're moving the same amount of air, but seeing less boost due to the loss of heat from the intercooler. So now you could actually shove a little more air volume down it to reach the same boost as before

[@Singh_1989]

A skateboard wheel would work for an idler pulley. I've used them to make chain tensioners for mini bikes and go karts. I reckon if it works for a chain, a belt would also work just fine.

[@twocvbloke]

For those of us in the UK, the currency conversion would be about £13.31 wide, cos we have no £1 notes (they went out in the 80s), so the engine's witdh is about 13 and a bit £1 coins (of the current generation, whether lizzies or charlies), or in £5 notes, that's working out to be £12.48, so cheaper to go with those I guess... :P

That 1 second difference in the acceleration test for the normal Insight can easily be explained by the altitude you're at.

[@robotcantina8957]

Interesting....I think we are at 1400 ft. Hmmm I recken that makes a difference.

[@GrantOakes]

@@robotcantina8957 yes it does. About 2% lower atmospheric pressure per 1,000 foot elevation. That's roughly 3% less horsepower for you, coupled with a higher than standard temperature would probably account for most of the lost performance, the rest I would attribute to normal wear of the engine. Love your channel and voice over narration. Meh, stupidcharger, and other 1 liners are a wonderful way to start my Sunday mornings!

We can park in the middle of the road (other than the main highway) for duration too. Rural Eastern Washington and rural Kansas have much akin, though you guys should import a few hills, valleys and mountains, heh heh heh.

[@oddojaggins]

The IMA motor on insights and civic hybrids have the advantage of delivering instant torque at any rpm so while 20 ft lbs isn't much the gas motor only makes about 90 ft lbs at a certain rpm band and that's a noticeable increase when you're getting 20%+ more torque. I love my 03 civic hybrid it feels quick when you drive it hard because of that extra oomph the IMA adds and manual transmissions are an amazing Duo of fun and tech that gets me 40+ mpg when I do drive it more civilized

[@robotcantina8957]

From what I understand the Civic Hybrid has a very reasonable gear set in the transmission and are great cars. The Insight has a weird set of ratios, and when the IMA kicks in its noticeable, but on my car it seems it takes a few moment after a gear change before the IMA starts helping.
