Birdman, I just read the post about the engine going bad, did you get to the bottom of why you had low oil pressure?? I am trying to get an idea of what is really required for a Busa in a car, there are companies that want to sell you all kinds of things claiming you need them for a bike engined car but in your experience what would you say is definitely required?? and anything you dont need??

Great question, valuable to myself too considering my build is a busa one and I have no driving experience with it yet!

The stock Hayabusa pan will not work for cars.  I found that out the hard way.

I dropped over $4000 for a dry sump system and it didn't work either.  This system had an external pump, that wouldn't put out enough pressure and leaked oil around the shaft seal.  So I modified my stock Hayabusa pan.

 

I cut 1/2 inch off the bottom of the Hayabusa oil pan sump, then welded a square aluminum sump onto the stock pan, at stock depth.  I made this nwe sump as big as I could to hold as much oil as possible.  The hangy down sides of the busa pan trap oil in the sides of the pan for cornering.

I also added a small baffle at the fromt of the sump to prevent oil sloshing away from the pick up durning hard braking.

 

I also piped in a remote oil cooler and remote oil filter using the oil filter bypass kit from Down's engineering.

If I was to go dry sump I would go with one of the kits that replaces the busa water pump with a new scavenge oil pump and uses the stock busa oil pump for pressure feed like this.

Here's a picture of my modified oil pan.  You can also see the elec actuator for my shifter.

Forgot to post this but we had a great track day a couple of weeks ago at Chuckwalla Valley raceway in southern California.  Had some really good laps, trimmed almost 20 seconds off my lap times by the end of the day.  I just love this track, one of my favorites.

 

Here's my video.

I can see why Birdman, great track......I wish we had your weather over here, it feels like it hasn't stopped raining in over a month.......

Boy you can keep the rain, been in the 70s and 80s here in Southern Calif where we're staying.  I'm going to go check out a new track today.  A private membership only thing called Thermal.

[Birdman]

Looked at the Thermal track, and even did a couple of laps, but not for me.  It's like a upper class ritzy country club, only based on a road track instead of a gold course.  $85,000 to join, $400,000 for a lot, and your required to build on it with in 5 years.  (Another $500,000)

No thank you, not for me.

Holy Crap.

 

I thought my £200/annum membership for Goodwood Road Racing Club was expensive.....

Some day I'll run Goodwood.  And Silverstone.

With the above membership you can run unlimited every day for free, and get free Caviar. BG.

My NASA and NCSA memberships are both $45, Willow Springs Membership is $75, and ORP $200.  I don't need another membership for $85,000!

A manual shifter instead of buttons would be a massive help. Feel free to tell me to go away but there seems to be a little hesitation when going for a button. I've used both a paddle system (similar to yours) and a well angled sequential manual shifter and the shifter is so confidence inspiring. Just my opinion :)

Edit: I missed a page, I see you made the change from the buttons. Epic build by the way

I have tried manual lever, buttons, and now the paddles.  I was to slow with a manual shift lever, the button system didn't have a blipper for down shifts, but this new flat shifter system from over your way with the blipper works flawless.  I love it.

It's a really nice system, I'm a bit jealous of your car aha :)

Hey Birdman, isn't this yours???:

Yes it is.  And that's me, the good looking one with the coffee.  That dyno run was back with my original turbo system
