You have done and incredible job on the car, I am very impressed and at some point would love to see it in person. Hell, I would love to see that beauty in action sometime, you should be very proud because that car is truly a work of art that you seem to drive like its meant to be instead of letting it sit. Congrats

Well,It's been a long time since any updates from me as this past season has been very hectic. I am not one to give daily updates as I much rather get the work done to make the deadline for another track date. In addition to playing with the Fiero I have also been actively racing my Spec Miata, working on numerous projects around the house and now,yes, putting together the BABY ROOM!
But let's go back to last winter............
The offseason upgrades for the car was to add air jacks and re-gear the transmission. The air jacks would make my life much easier during the course of a track day as it is a pain in the butt to lift the car to put the airdam and rear splitter on and off the car in order to get it into the trailer. They also make working on the car much more enjoyable and ,well,....they are just too cool to play with!!
The transmission had to be next as the ratios were just wrong for track use in that 1st gear was way too short and 4th was too tall. In addition,if you have ever shifted a Porsche 930 gearbox you would agree that it is terrible!! It feels like shifting a Mack truck! I really wanted to install a Hewland racing transaxle,but at $15k,it was just out of my budget,so I would have to convert the 930 box to "dog" engagement from the Porsche style syncronizers. With this setup, using the clutch to upshift and downshift is not required. On upshifts you would put just a little pressure on the gear lever in the direction you want to go and just give the engine a little lift off the gas pedal(just enough to unload the drivetrain) and CLICK! in a blink you are in the next gear! When downshifting you can now left foot brake and keep your right foot on the gas pedal to give a "blip" to syncronize the next gear and it will go right in! There is just one company worldwide that makes replacement gears in dog change style for the 930. So I ordered them up from Albins in Austrailia and had to wait 8 weeks to have them made. Meanwhile I started work on the air jack mounts on the chassis:

Here is the kit from Palistini with everything needed (airwand,fittings,airline,jack cylinders,and safety stands):



They are vey lightweight,just 3 pounds per unit:


Mounting brackets roughed in and finished:
Front

Rear




This is where the air wand is attached to the car to lift it:


So with the turn of an air valve :


you go from this.............


To THIS!!!!:


Next time...............The long awaited (and VERY expensive) gears arrive!!!

Great to see an update Dave! Out of curiosity, how much do those jacks cost? I find it extremely annoying to drive my car up onto pieces of wood everytime I want to jack the car.

Everything looks great!

Check out my build!

One of the issues with a stock Fiero as opposed to the race car is the amount of suspension travel. I don't know if the air jacks would raise a stock suspension high enough to get the wheels off. Notice his last picture and the amount of suspension travel downwards.....almost none
doublec4 OCT 17, 06:06 PM
Thats a good point. However, it will definitely get the car high enough that I could crawl under for whatever reason, as well as making it easier to get a floor jack under.

Great to see yours is making your life easier !

The Palistini kits come with cylinders with 9 or 11in stroke. I went with the 11in as I wanted to be able to get under the car to work on it as opposed to just getting the wheels off. The kit as seen was $2200 as opposed to $5 to 7k for a "real" system from AP . The difference is in the hardware.This kit is geared toward the grassroots club racer and not someone who is going to run the 24h of Daytona or Le Mans. The fittings are the "push lock" industrial/truck airbrake type with poly tubing,not the more expensive aircraft fittings and braided steel/teflon high pressure tubing. After a full season, I can't complain about them as they have performed well so far. My only comment would be that I would have liked a larger bore cylinder so my operating pressure could be lower. I need to run around 375psi of nitrogen to lift my car with a heavier car needing more. This is just how it is even with the AP systems although there is a new company with large bore cylinders (4in I think) marketed toward Corvette guys so they can lift their car with shop line pressure( around 150psi),but I'm not sure of the name of the company.
