My 72 3.0 progress thread: Project F-914, Adding transmission cooler. Options

[Krieger]

The guns operate 360* and are self tracking .50 caliber...

What's the latest, Andy?

[Krieger]

I've been driving the heck out of it! Lots of autocross. It was running hot at Thunderhill on a 100* day. I took both the grills off and the oil temps dropped from 250 to 210. Seriously that restrictive. I know I needed to come up with a solution that inclded a grill. Instead of having all the holes and a tight grill I made one large opening with 1/2" mesh from Home Depot. I'll be at Buttonwillow in a few weeks so
I report back. I think it looks better too.

Andy, I've seen applications where additional holes were drilled in the space between the factory holes - the part behind your valance - that would also increase the air intake. Not sure if you're catching all that area though.

The spoiler that is in the pic above I only use on the street and autocross. It has never gotten hot. I use a different one on the track. The one for the track is more of a splitter style, is much lower and does not block the oil cooler opening in any way. This weekend at Buttonwillow my oil temps never went over 180*. So this small mod has been a complete success!

Andy,

On your Easy Car Lift, what size are the spacers you are using? Yours seem to clear the engine compartment, where mine hit the donuts , but make it very hard to drop the engine out.

Thanks for the update on the cooling inlet also.

[Krieger]

Hey Stephan. My aluminum rails are 29" apart. The rear donuts are not centered on the rails when I lift. They are ofset toward the edge of the rail. Maybe 3" from the edge. I do not pay attention to the front donuts. I put 1/2" blocks of wood under the body on the edge where the rocker and under body meet.

I got tired of not being able to see the speedometer on the track, so I bought this GPS HUD on Amazon for $68! The 0 is off center, but I anticipate seeing two other digits to the left of it (IMG:style_emoticons/default/biggrin.gif) . It also has a port for an external GPS antenna. I tried it first in my work car and it seemed to change speeds with only the slightest delay. This unit also has the ability to be "calibrated" to the correct speed. I did so with a bone stock vehicle.

I found it was necessary to add the supplied film for better viewing and it goes with my aviation theme. You don't need to use it, but you'll get a double image because of the two layers of glass. I want to be able to have the quickest look at my speed without having to spend any more time than needed. It went on just like a piece of window tint. The unit plugs into a power port, which I had recently added, and has an on/off button.

Nice, I like that idea... easy to see without looking away from the road too!

Nice build, where do you autocross at?

[Krieger]

Thanks. Santa Rosa airport is the place to be on some Saturdays!

[Justinp71]

Lucky, to have a place so close... We just get a local autocross once or twice a year by SCCA and they don't give you much seat time...Otherwise we drive to Stockton for Zone 7 PCA.

I am adding a transmission cooler. I want to do my best to keep this 901 alive and minimize time between rebuilds. Occasionally, I was having difficulty shifting on 100* days. This is where I decided to run the return-8 lines back to the transmission. I was lucky. I found a guy to weld magnesium. He added 2 boses for me to drill and tap for npt. I chose these two locations to cool the ring gear and put oil in the front of the case and to cool/lube the gears.

[Krieger]

I bought most of my parts through BAT in Florida. I drilled and tapped the case for a temp sensor and the pump activation switch. Patrick Motorsports has the pictured oil plug to AN-8 oil pick up fitting.

[Krieger]

Here's how I plumbed the system. Still some work to do.

[Krieger]

Here is the Setrab cooler with Permatex ultra black built up to make the seal between the fender and the cooler.

[Krieger]

My patented 4 post attatchment system! Metric threaded rod, lots of nuts and washers. The nut on the bottom left I welded to the long.

[Krieger]

And the scoop! It is stainless steel that I glass beaded.

[Krieger]

Okay, I know for sure the last two pics were taken with my phone verticle. Why are these getting rotated?
