Motorcycle Powered Car - DIY Airbox

I built a custom Air box for the Motorcycle Powered Fiat out of aluminum.

Nice refinement. Car seems like fun.

[@jordanmclaws7027]

Videos are getting MUCH better, I’m enjoying the extra effort between the voiceovers and the editing. Keep it up!

[@Jerod_Helt]

Thank you for that. I’m trying to focus on quality over quantity. I’m comfortable in the garage, but still have a lot learn about editing.

[@Drunken_Hamster]

I think it would be MUCH quieter if you reworked the engine location by flipping it around and lowering it a solid foot or foot-and-a-half to make it a rear engine that fits neatly in the trunk. Then you could have storage where the engine currently is, or even make space to allow you to recline the seats a little.

[@lunabouch]

Great update and your fabrication skills are amazing. Thanks for this 8:00 minute + amazing one of a kind.

[@craigleemehan]

Great to hear from you again. To my elderly ears, the new airbox appeared to take your noise level away from irritating to really cool.

[@bagushideunk8039]

Glad you'reback I hope you are always healthy, friend

[@lostwrenchgarage]

Glad you’re back! I really enjoy your videos- hoping for a new build series but I’ll be watching whatever you put out there. Your editing is superb. You really tell a story with your videos 👍🏼

[@N4sir98]

Nice air box, Jerod! The tig welds look fine. 👍 It's great to see a video from you. Don't be a stranger.

[@ronpackwood8772]

👍👍✌️ welcome back

[@tanner8355]

Keep in mind that your head is as close (probably closer actually) to the engine as it would be on the motorcycle and people wear helmets riding those bikes which insulates them from a lot of the noise. So I think it being too loud for you is just gonna be the nature of the beast with this car. There are thousands of explosions happening inches from your ears after all. Just watched this series from start to finish and you do brilliant work. Especially considering you’re just shooting from the hip without much planning or CAD or anything. Criminally underrated channel but you have a new sub in me.

[@ideabrickworks9043]

Glad you are back! Love your stuff.

[@sidney9534]

I actually dealt with this on my scooter. What worked best is a box with baffles, very similar to a chambered muffler. Also some kind of sound absorbing material on the inside walls is useful - some stick on foam works well, just have to be secured so it doesn't get sucked in. Also there will be noise just purely coming out of the engine, but I don't see how to supress that unless you make some enclosed compartment, or make a hardtop. Totally relate to quiet = fast. I'm probably the only other person in the world who drives slower the louder it is. It is weird, most people have it the other way around, also the later the hour and quieter neighbourhood, the fester they drive.

[@mariopizzamanmario8563]

Great project, seems to me the original Fiat is a bit lower though. But it is always going to be much noisier as you have much more RPM (bangs per minute). It will also become more quiet if you make "trunk" for it (plenty space in the rear).

[@joell439]

Fantastic update. Sounds great 👍

[@waynemiracle8928]

I’m sooooo glad to see you back on KZbin! Your talents are amazing!

[@faulker6751]

nice build thus far! i just came in on a random vid, new sub here for sure! a suggestion for the noise , try a piece of alum to make a shield/ aka false fire wall , line it with the fire proofing dynamat . that can mount to the header downtubes. less heat and noise. my 914 /fireblade was as yours is now. that solved my problem .

[@philiprogers5772]

whilst i commend and admire the engineering and love your channel you are doing this just at the point we are all moving to electric.

[@toddzachary4891]

Another great video! I own a 72’ FJ40 and I loved watching this build as much, if not more than the land cruiser build 😂😂 Well done!

[@johnapel2856]

Yay! He's back! Always glad to see something from you. It's been a while, I hope Walter is good. Thanks, and Woof to Walter.

[@chrisryan9986]

Annnnnd ..... He's back. Sweet improvement to an already cool project. Really nice work

[@nycLPplayer]

Make an insulated box that goes over that part and amazon dynamat everything you can

[@matthandy7039]

Great project! Thanks for sharing

[@bobbypomphrey1770]

Welcome back brotha!!!! Love the build. You seem to be coming back with a vengence. Love the voice over. Good luck!!! One day i will do this to my m.g

[@motorv8N]

What a fantastic project. Going to go back and watch the build videos. Looks like changed your channel name?

[@Jerod_Helt]

Sweet! Yes I decided just to use my name as the channel name👍

[@terrencehall7264]

A turbocharger will reduce noise while giving you more torque and horsepower.

[@Jerod_Helt]

I’ll look into that

[@TheINDIAN]

Hey is there by any chance that you will be building another motorcycle engine swapped car in the future. Would you like to try and beat Gordon Murrys Rocket cars weight record of 380 kg using a tube steel chassis exactly like the rocket car but with a KTM 1390 or 1290 (or a motus 1650 engine u could install an A/C ) engine as it has a semi dry sump engine. With a body from a lotus 49. And as a suggestion are you open to having a side to side dash mounted shifter (i.e left upshift to right down shift ) with the clutch mounted on the shifter lever to increase shift speed and clutch relase smoothness.

[@JakobKsGarage]

Can't you pad the box on the outside with some neoprene or something similar noise reducing? Will also hide the not super nice looking alu welds. Plus I think matte black and red goes well together (think Abarth..).

[@johndemeen5575]

May be some type of shooting ear muffs they have a thin profile, and noise canceling. From St.Paul,Minnesota.

[@panickedmechanic7536]

Holy cow, never ever grind aluminum on a bench grinder! Aluminum, brass, copper and other soft metals will clog the stone, when it gets hot, it expands, cracking the wheel while it's spinning at 9000 rpm! For aluminum, get a belt grinder or quality hand files.

[@Jerod_Helt]

Good to know. Thanks!

[@rjung_ch]

👍💪✌

[@MKBuiltt]

I never considered how loud it would be but needing earplugs makes sense. Motorcycle helmets definitely do a good job of dampening sound. Also, what did you end up doing with the miata diff you built for the fiat? If you still have it I'd be interested in buying it to save me some fabrication time

[@Jerod_Helt]

I still have it. You can email me at [e-mail]

[@MKBuiltt]

@@Jerod_Heltcool! Thanks

[@LucasTax97]

Hey Jerod! I'm curious, is that sweet gear whine primarily from the Quaife differential or the Suzuki transmission?

[@Jerod_Helt]

It’s most likely from the chain

[@mountaindew20]

can this motorcycles engine swap give u top speed 250+/kmh in ur car ?

[@Jerod_Helt]

The top speed of this car is just over 100mph / 160kmh

[@ChrisPorsche]

Hows the 356 running?

[@Jerod_Helt]

Very well. I’m getting it ready for a long road trip right now. I’m doing a drive with the 356 Arizona Outlaws in a few weeks.

[@gabrielrionegro6645]

👍🏻👍🏻👍🏻👍🏻👏👏👏👏💪💪💪

[@giangelosantilli2075]

Hey, i was wondering what the gas mileage your fiat is compared to what it would have been stock

[@Jerod_Helt]

I haven’t calculated the MPG but due to the gear reduction the speedometer is set to around 45% of what it was. So basically the engine revolves twice as many times per mile as it did when it was a bike. So I would guess it gets about half the mpg as it did as a bike.

[@giangelosantilli2075]

@@Jerod_Helt that makes sense, thanks

[@nightstorm9128]

The sound is the whole point of using an engine like this,,,,If you didn't want a loud sounding engine ,,Why didn't you use a Honda dueval 1200 ,,or a Honda gold wing ,,You would have got around the same HP but much more torque,,And half as noisy,,I mean it's a gsxr ,,you must have known it was going to be very noisy,,

[@pironiero]

Borrow everyone's style, try it out, then make your own, there is nothing original on this world, keep it up
