Saturn powered Bonneville Racer

[hitz]

This is a project that started about 6 years ago and is going through through changes now trying to be ready to run again in August. A friend of mine covered it on his website through the early part of the build. This is a low budget build. Here's the URL to the early days (years?)

Re: Saturn powered Bonneville Racer

I just clicked through a good portion of that, some good reading there for sure.

This is a hell of a project, awesome work, can't wait to see more!

Excellent work on the transmission adapter, that was really cool.

I find this super intresting...



How long did it take you to modify both the intake mani and the individual Busa TB's to work?

Re: Saturn powered Bonneville Racer

Awesome work. You should help McLeod out on figuring out our clutch issues.

Just read through the entire thing. Absolutely amazing!

Re: Saturn powered Bonneville Racer

Doki,
The intake manifold was made from pieces of two stock Saturn manifolds and aluminum tubing where the Hayabusa throttle body assembly attaches. It took about 80+ hours to fabricate the manifold that included some lathe work on the tubing where the throttle bodies attached. It was constructed to fit the throttle bodies as they came from the Suzuki factory so it was a simple task to install with out modification. They included the 24 # fuel injectors. I used the TPS (throttle position sensor) from the Suzuki also. The throttle is hydraulically controlled using a Mazda clutch slave cylinder and aftermarket pedal assembly (Winters). The Electromotive Tech II ECU uses a laptop and TechII software to tune the fuel and ignition.

The curve in the intake runners was necessary to get the the length of the intake track I thought I needed and to keep it inside the body. I also had to tilt the engine 14 degrees to have room for the intake system. This caused the oiling problem I mentoned before.

Re: Saturn powered Bonneville Racer

have you thought about either cutting up a stock pickup tube or just trying to bend it towards the low point of the oil pan?

Re: Saturn powered Bonneville Racer

at 14 degrees the oil pickup is still well covered but the top of the oil is very close to to the pan rail and the crank throws pass very close to the rail. I think it's beating the oil to a froth. Good thinking though. Thanks. It was no problem in the shop running at 6500rpm but with the enginewide open for 2 miles other things start to show up.

Re: Saturn powered Bonneville Racer

What about using a 3rd gen (01-02) oil pan? they are bigger than the second gens due to the tie plate and larger oil pickup that the third gen motors have.

Re: Saturn powered Bonneville Racer

Some damn nice work for sure.

Hey Harvey, I sent you a private message

I'll give you a call toward the end of the week. Like to hear about your Saturn experiences.

Re: Saturn powered Bonneville Racer

late entry, I know....
I noticed the pitch on the engine....the main oil returns are on the intake side of the head. There are 3 drains on the Intake side, and only 1 on the exhaust side. That's why the exhaust cam is frothing the oil...it's bathing in it. That would also keep too much oil at the head, and little back to the pan.
The timing chain is getting well lubed though. LOL. It's just routing the oil in the farthest path to the pickup, which is now at the front of your engine. With some g's and rpm's, very little would get to the pickup tube at all.

I know you fixed the oil supply problem with a dry sump, but I wanted to let you know why the original setup had failed. I don't think you're completely done yet with the oiling issues.

I look forward to seeing the results...keep us posted!
btw - LOVE that Chevy. it looks fantastic.
