Hi Guys, it's been a while. My car is done and ready for a new owner to take it to the next level. I designed, engineered, fabricated and built the car myself. Autocross, Hillclimb, Track Day, Car Show! The car has two Porsche designed Subaru EZ30 six cylinder engines that Were connected at...

I need someone like Overhaulin to take this to the next level. I don't have the money, emotions or technical ability to take it any further.

I'm using 2007 Tribeca engines with the individual exhaust ports.

First parking lot drive. The engine is still not tuned and idle adjustments need to be made.

Dyno's cost money but my tuner will probably want to use one. I never built this car with the intention of it being raced or even driven hard. I'm 67 so I only care about what it looks and sounds like. It will be driven "Spiritedly" but that's it. Can't wait to double clutch it going into a...

Hi Clayton, I have the front engine attached to the rear engine's pulley via two rim to rim flex plates. I found out the pulley material is very weak so I'm changing the connection design to one of two I have come up with. When I redo it, I'll post it. Jack

Go to JB91710 on YouTube to see all my videos. They explain the 917/10 engines in detail.

Of course, that includes the 917 Lemans car and the modern F1 car but I still had to wait that long to get the 917/10 started because no one had a computer to run the Subaru EZ30 engine. Go to JB91710 on YouTube to see all the videos.

It has taken 8 long and painful years but my 917/10 is running. It is Not tuned and the video does Not due the sound justice. More to come! Hi Fran! Home Built Porsche 917/10 Replica Start Up for the First Time! Finally! - YouTube

Jac Mac, I had looked at 30 and 60 degrees. I'll have to look at 120 and see how that works out. jack

I will be firing the #1 cylinder in the rear engine and the #6 cylinder in the front engine at the same time, and so on, so that a cylinder will fire on opposite sides on each engine. I don't think you can fire one cylinder at a time between the engines, like a 12 cylinder engine, without having...

I'm attaching some photos of my STP 917 as it is coming along nicely. Jack

Hi Patrick, This looks great! I was thinking about the rubber half shaft donuts of old but these look much better for my purpose. Who is the manufacturer? Jack

I'm still figuring everything out but it will be two late model Subaru 6cyl, 3.0L engines joined at the crank with a piece I designed. Both engines will be bolted firmly to the chassis with other braces to make the engines one. So far, I'm planning to run both engines off of one computer with...

Big changes on my end. Construction is over for me due to the economy and that a company will hire a person half my age rather than me. I've recently stopped working on the "Prototype" and teaching car. Now I'm focusing my full attention on a production car to make money. The new car will...
