Does it make sense , putting a bike engine in a car

In this video I address the issues and factors of placing a bike engine into a car. Is it a good idea or not ?

That was an excellent presentation! Especially the torque segment.

That torque story was only half of it. It's not what the engine makes but what actually gets to the wheels. The bike engine can run a much shorter final gearing, in fact double the reduction that the car engine can because of its double width power band. So back wheel thrust will be about equal.

Excellent video once again. Thanks and keep them coming. In your calculations 11000 was the right answer. 4 x 2750. ( not 2250). Pass on my regards to Old Rusty 😁

You are correct, I need to go back to school... should never edit a video at night .....lol

Long time watcher, first time commenting. Horsepower is a measure of total work done over time. To get it, we multiply the torque by the rpm (oversimplified). this is why an engine which generates less force (torque) per power stroke, makes up for it by having more power strokes. When you used a longer bar on the bolt, you DID increase the force, but you also increased the distance travelled, so the total amount of work performed was the same. This is the basic principle of mechanical advantage.

This was a great video. I have a Lotus 7 and I went with a Toyota Beams 3sge. Some days I wonder if a Suzuki Hyabusa engine would be better. Your video helped me remember that I am on track and there are advantages to the car engine. Your explanation about torque and Short and long stroke helped me understand. I also have to keep in mind that torque feels nice. When the throttles open wide and the engine pulls strong from a low rpm for a long time it feels nice. Thanks again. Rex in New Zealand.

My pleasure and thanks for watching. I also do enjoy torque at mid and low RPM's. Enjoy your racing

That was a very nice and detailed video. I finally understand the difference between a car engine and a bike engine. Thanks Steve.

Great video, very interesting comparison. I run in the F1000 series here in the UK, we run mostly gsxr 1000s and car and engine weigh 320kg.

Indeed, and that works like a champ... Did you ever race against a FF 2000 ? on a track and how did that end up ? Of course yours is fast due to the HP/weight ratio

@finnguitars9869 3 ай бұрын

Clear explanation Stephan! A small addition to this video: a short stroke can also be applied if the overall weight of the vehicle is low. A low mass needs less torque to accelerate. Therefore, a choice can be made to give a sporty motorcycle engine a short stroke rather than keeping the dimensions of the engine in check. Keep up the good work!

Thank you for a very thought provoking video. I initially thought a motorcycle engine gave formula 1 technology to the car, but your well explained problems/benefits video is most useful. Thanks again and best regards Marc. Australia.

Firstly ,the obvious choice for a car due its weight is the Hyabusa. A little smaller in capacity than the car engine but with no modification considerably more powerful with added benefit of torque that is needed for the greater weight of the car. Smaller high revving engines simply don’t have the torque to do the job.

Eish Steve, I have to watch this video 3 to 4 times before commenting. Informative but my mind sometimes slips. Eish Moshitoa south Africa

Very interesting video, thank you! I wonder what the result would be if both race cars had a car engine, but one of the engines was oversquare and revved very high. So all things being equal except for bore/stroke ratio.

@D3Sshooter 3 ай бұрын

Thanks for the comments, well one would have more horse power, but the torque will be relatively less. Here is an approximate assessment based on a simple calculation: CAR A - 300HP at 20000 RPM, CAR B -150HP at 5000 RPM. Results in Torque: CAR A= 106Nm CAR B= 213 Nm Of course that is engine torque , wheel torque will depend on many things (diff ratio, gearbox ratio and gear). The track type etc...Lots of acceleration due to turns and breaking requires torque to accelerate.. Long straights, are less demanding...

what a bike engine conversion does is replace a lot of the old hard to find racing specific parts. dont think many bike conversions happen from a good running race cars but from ones that are blown up or have been canibalised to fix other cars. in that way its a cost-effective if labor-intensive way of getting a car back on track. that it is somewhat competitive is just a bonus. also you can have fun with the bikes aftermarket. clutches are also a problem for motorcycle and atv drag racers so there are after market solutions like lockup clutches and recluse torque drives. something to look out for the extra strain on the clutch in a car will definitely shorten the life of the clutch baskets, the metal clutch plates digging into the aluminum makeing them not slide freely and hanging up, causes irregular clutch plate wear and slipping. there's lots of replacements its just something to check. 140hp is no where near where bikes top out. ktm 1190 and 1290 motors are dry sump thin v twin engines that should be easier to package in the cars frame, also 160-180 hp depending on model.

Thanks for the comments, and yes there are special bike engines that overcome most of the challenges as you stated in your write up.

I suppose being race cars the most important consideration is which one is quicker?

Yes, and both engine types have their Merritt. Pending the track and use

@slartibartfast2649 3 ай бұрын

8:10 5500/2=2750, so 11,000 labor strokes per minute was correct 👍

horsepower is how 'fast' you hit the wall. Torque is how 'far' you take that wall with ya.

Did the Smart car originally have a bike engine, 3 cylinder? I saw a German ytube where a highly tuned bike engine was placed in a Smart Car and it was fast on the autobahn.

yes, that is very well possible... Bike engines are powerfull....

@blatopasteka2015 3 ай бұрын

Great video! Which one is faster on track ?

@D3Sshooter 3 ай бұрын

Well on a small track with lots of turns, the car engine was faster, less shifting and better torque. On another track that can be completely different

The bike engine car is much more like F1 than the car engine one. Of course it's going to be harder to drive. I mean, you're not making a fair comparison either. 1400 cc vs. 900 is not fair. Put a Hyabusa 1300 engine into that other car, and put a diff in there as well. I bet that will make a huge difference for you.
