Hey Guys...This is a re-post from the "Garage Forum" Hope its ok?

Some 914 race car style questions:

Anyone know who carries Kirkey Seats in the PNW-Seattle area (or something similar)? Which style fits best?

For those of you who have roll cages and have changed the pedals.....
Did you use "swing style" to mount to the crossbar of the cage or firewall for brake and clutch and or throttle? Im trying to get away from floor mounted if possible? Not opposed to a hyd. clutch either....using stock 914 transaxle....

Thanks for your input....

Pictures always help if anyone has some.....

Bought my Kirkey seat from Summit. No drama.

[neilca]

I bought a Kirkey road race seat from Behrents. They had the lowest price. I will have to get some pictures.

The pedals are Wilwood swing from the top with the cylinders behind the pedals. I had to make a special mount. I will try to get pics of that this weekend also.

Thanks everyone...cant wait to see the photos..

Here are the pictures. The master cylinders are Howe G3. They are neat because the seal doesn't drag across the hole in the cylinder wearing out the seal. BTW the whole pedal assembly is removed with just the four bolts. The lines are extra long so the assembly can be raised and emptied without a big mess.

dang you must be tall because thats exactly how I mounted my Kirkey!

[neilca]

No actually I am short and fat! (5"8", 250#) I do sit very low in the car. I think my dash is further aft than stock, that may be throwing you.

[quadracerx]

Well Done....thanks for the pics...I know know that it should be doable...Not sure about the throttle pedal and cable/linkage but I think based on your pics that the "swing style pedals" for clutch and brake will free up floor space. I have a frame outrigger that is in the footbox area that I really cant move...so this might solve it...

What did you do for a slave cyl. for the clutch?

Thanks again...great pics

Neil's throttle linkage is necessarily different since his car is right hand drive. I like it.

I have a swing mount brake pedal similar to Neil's. I left the clutch and throttle on the floor, more or less like stock. I also move my whole pedal box about 10-12" forward in an attempt to improve weight distribution. I had to move the front swaybar to make room for this.

Scott...

Do you have any pics of your setup?

Thanks,

Tilton pedal assembly.

The clutch slave is a Wilwood pull cylinder. I used one of the diff cover plate bolts to react the load. I will have to get a picture of this cause it is important that you spread the load cause the stud cannot take the bending stress.

Chris, great minds think alike. I mounted my oil cooler just like yours. The only difference is I raised my fuel cell so the incoming air would go underneath it. I also added an additional cowl grill to let the air out. I will get some pictures of that too.

[neilca]

Scott,

You are correct. In previous formula and sportsracers I have had, the throttle cables were always binding. In this car the cable is absolutely straight.

[neilca]

First here is a picture of the oil cooler set up. I love having the cooler mounted high and out of the way of danger. BTW I do not think this will work on a car with a windshield. I think the flow may reverse, however I can also see where this may relieve the low pressure commonly found on the cowl making the air flow across the windshield laminer. Some tuft testing would be in order.




The Wilwood pull cylinder is below the CV. I think you can see the hookups. The cylinder had to be spaced away from the case for alignment. I used a longer stud in the case and I made a nut that worked as a spacer. This moves the shear point of the assembly to the end of the nut thus reducing the torque arm. The nut very nicely spreads the load into the case. I run a double disc AP 7.25 clutch in the car and have had no issues in 2 years.






BTW I am not missing a CV bolt. That is where the roll pin is located and I have a 911 boot on it.

How are you running that car legally in SCCA with it being a right drive car?

[neilca]

Good question Brett,

The car is only legal in the SPU (Special Production Under 2.5 liters) class. It is a regional class only and it has one rule, it has to be under 2.5 liters. It makes for some interesting fields of Pro challenge cars, legends cars, home builts and some GT3 cars with big wings. The lap times are also very wide spread.

[Brett W]

Yup very familiar with SPU. Great class. The nice thing with it, is you don't get the pleasure of be bashed around by the clowns driving retired stock cars in SPO. So all of our nice small cars don't get run over by those guys.

Nice setup and great workmanship. Someone knows how to work with aluminum!Looks like a fun car to drive as well.

Question: Just wondering how you get any airflow over the cooler mounted where it is. Do you have airflow coming in somewhere, other than the vent.

BTW I ran SPU at the Cascade Lakes Hill Climb and like you said in a later post there were some interesting cars. Nice finding a class where you can compete without any major disadvantages. The Cascade event was SCCA sanctioned, so wondering why more SCCA events don't offer the SPU class?

Randal,

The air comes in the front air dam like all other 914's (that part is not shown shown in the picturres) then under the fuel cell. The air enters from below the cooler, moves upward and out the cowl.

Thanks for the compliment. It took me 12 years to build this car, time and money being what it is, scarce.

Ducting the air from under the fuel cell to the oil cooler was done so clean we can't even see it. Have any progress pictures of that part of the build? If not how about a shot from the drivers side looking down below the cooler.

Also would love to hear about your motor.
