Holy ****. I have always wanted a super high rpm screamer engine in a car. That sound is glorious.

I saw that this morning and was going to post it as well. I always thought one of those engine would be great in an AE86 Corolla or Miata. A little cost prohibitive though.

why didn't they just cover the box? why is it sealing to the hood?

why does it only make 300hp?

What is the point of having ITBs if you cant see them?

Looks like just another "because racecar" build that is not actually a race car. It probably has no class it could run in and was just built to be on speedhunters and magazing covers.

I am sure it could run as a time attack car.
to be fair these types of engines see Powertec etc that are v8s created to use motorcycle heads/throttle bodies are mostly aimed at smaller prototype cars like radicals, wolf, Juno etc where their power density and lack of torque thrive.
They do well at being a sort of mid level race engine cheaper than Judd, Zytec, AER etc.
However they are really too expensive for the average hobby type race care and with limited experience/parts etc they never really catch on. See Hartley V8.
Still it is cool to see when people put them in lightweight OEM bodies.
It would be cool to put one in a miata. Would a high revving K24 or F22 be cheaper?-yeah alot.

It almost looks like there is a panel filter between the snorkel and plenum. That or there is a filter in between the bumper.

I had an 'accident' when I saw this on speedhunters last night. I've been interested in the development of the twin hayabusa V8 for a bit. I believe this is the same company that was working on the 'V8 in an atom' project.

I wonder if you could fit one of those easily into a miata...

Here's the pic that midtenn linked:

I know dpcars.net put the Hartley hayabusa v8 in his atom.

On the other end of the insanity spectrum, there's guys who go the other direction & build 4cyls that take big pro stock v8 cylinder heads.

Wut. I know it's one the same level as 'let's kitbash two hayabusa motors!' But why? Do the v8 heads flow that much better?

JUN always built things over the top... this doesn't seem to be any different than what they were doing in the heydays in the 90s.

Sounds fun to me. Id image the cylinder heads are pretty compact considering the displacement, should leave lots of room for devious plumbing of turbos and such.

Do these setups run a balance shaft?

Putting pure motorsport heads on unmodified productions blocks then?

I should take a HG and drive down to MDS and see if their 91mm c-c head can be crammed onto a BP block.
Rhys Millen got this head modified (flipped etc) to fit on a Hyundai some years ago (don't now which year or which Hyundai).
Cost would be into the $10-15k I assume but it would be nice to know how much custom it would be.
The main problem is getting the oil and water drains to match (and not crossmatch ).

They flow more because they are physically much larger. Thats a ~4.0l 4cyl.

Some midget cars run 4cyl's based off 'small blocks' of various manufacturers. Most are a type of NASCAR head.





From what I understand, the K24's (and other traditional native DOHC 4cyl) that compete against them are not as competitive...except for the SOHC Esslinger which is Ford Pinto based.

No balance shaft. This should be the block in the above post, or an earlier version of it.

Learned something new today, pretty interesting to see motors based off half a v8.
