Ernie says "I have been wanting this car to go faster so I rebuilt the motor years ago. It wasn't fast enough so I put the dual Webers on it. It went faster but not fast enough. So I installed Nitrous. It went faster but not enough. You can see where this is going...I wanted it to still go faster so I supercharged it. Well, it's faster!!"

Revision as of 06:32, 18 March 2009

Ernie "datsa73", who lives in the Seattle area, has a nice Datsun 1200 2-dr sedan with a unique custom-built twin-Weber downdraft intake system. Ernie says "I have been wanting this car to go faster so I rebuilt the motor years ago. It wasn't fast enough so I put the dual Webers on it. It went faster but not fast enough. So I installed Nitrous. It went faster but not enough. You can see where this is going...I wanted it to still go faster so I supercharged it. Well, it's faster!!"

I run one NOS and one Fuel nozzle right into the intake between the two carbs.

I have only ran the car on an 1/8th mile track at 9 second... I am running a electric fuel pump that pushes 8-10 pounds of pressure which seems to work fine. The blower is a screw type and it does look like an eaton. Not sure if it really is. You can google them on ebay. They run about $450. It is clutch drive so I installed a switch on the dash.

It seems to run fine. I am still able to run my RPM's up to 8000 on full boost with NOS. The A15 motor is really holding out.
</blockquote>


Ernie rebuilt the A15 during the winter of 2008/2009 "about 10 years since it's last rebuild". After dissembly, it was clear it didn't really need it. The bearings and rings were in great shape.


Now Supercharged

March 2009. As if a 50-HP Nitrous system is not enough, Ernie has added a Mercedes CLK Kompressor (supercharger) to the A15. The blower is driven off a Ford 5.0 pulley bolted to the crank in front of the existing A15 pulley.

I finally got this project done and it only took me a couple of weeks.
