Don't know if I'll make it that far west racing this one! Maybe halfway, like Topeka... I'm shooting to have the car on the track for some testing in early May. My big hold up now is the fact that the Aim MXL Pro I ordered has been backordered for over a month.

What hatch are you using? Looks nice, Tripoint, AWR, Japco? I need to drop some serious weight from mine, it's a hefty 2900 wet, w/me (155#). Of course it is not an EP car, just wish I had known more when I started... I look forward to your updates, keep'em coming, Carl

I made the all the body panels myself. One of the guys I share the shop with used to build boats and he made all the body panel molds. When I was ready for the hatch frame he walked me through the whole process of mold making etc. (he runs a 'vert so he didn't have a hatch) The frame weighs just under 4lbs and the 1/8th polycarbonate is about 11lbs so the whole package is just under 15lbs instead of the stock 57lbs.

Everything you see was done by me. Body panels, cage, paint, wiring etc etc. The hood weighs 14-15 lbs and attaches with hood pins. There might be $25 in materials.

Can you show us what you did under the hood with the front of the cage? That looks like one stout cage.

The fenders look great along with the hatch. Several racers build there own fiberglass pieces. Most of them do so because they don't like (or don't want to pay the high price + high freight) what's avaliable commerically. You could for sure go into the fiberglass business.

Here's the engine compartment. I have been mocking things up so it hasn't been painted.

That's a very nice looking car, the cage is beautifully made and looks well designed. The body work is also very good. I really admire people like you with the skills to do so much of the build on your own.

Wheel size is limited to 15x7. Tires are whatever you can fit UNDER the fender even if its flared. We run 9.5" wide slicks that are specially made for a narrow rim.

On another subject, I put the car on scales today. I just wanted to see what my neurosis about adding lightness to the car has gotten me. I gathered all kinds of parts that aren't installed on the car yet and put them in the general location they will be in relation to the wheels. I didn't add any fluids so these are dry weights but with me in the car. One thing I didn't account for was exhaust pipe but a did throw a muffler in the pass. corner. There also was no starter.

LF RF
540 528

LR RR
563 478

TOTAL 2109 lbs.
My weight is 189 on one of the scales. So the car is 1920 dry
Minimum weight for the class is 2350 lbs with driver.

Here are some shots of the 'office' under construction. After being on backorder for over a month my dash/dataq system finally showed up. Its an AIM MXL Pro 05. I'm making my list for all the sensors and extra wiring I need.

The whole engine harness has been pulled back through the firewall and is in a ball by the ECU shelf on the passenger side. I'll be painting the engine compartment this next week.

You'll love the hell out of that dash once you get on track. I drove a customer's car in an enduro with it, and it's really nice. He wired in some bigger and brighter warning lights (superbright LEDs) that make it impossible to miss. He did it for the video camera, but it makes it hard to say, "I didn't see the light....".

Scott, the Turner got punted off the track by a Corvette on the outside of 17 during the Enduro. The front right corner is crushed.

Which minute of spare time were you looking? The first or the second one

Its been a while since I've updated info on the car. I spent the Fall traveling doing the Zoom Zoom Live Tour and I got no time in on the car. I dug up some pics for everybody's enjoyment.

There are two of my clutch set-up using a flex plate. I had some QuarterMaster clutch stuff laying around and figured I could save some weight. I had a spacer made to fill the gap in the dish of the flexplate. I could have turned it myself but then I thought,"This thing is going to be spinning 9K!" so I had a friend who does it for a living do it. It turned out great. The whole thing came in at 12lbs 7oz including the counterweight and hardware. The whole clutch and flywheel package weighs in at just under 18lbs. The stock assembly weighs about 36 lbs. The big thing is rotational mass though and this set-up is low.

The other picture is of the brake duct I made. It puts all the air into the center of the disc from a 3" hose. This will keep the disc from having one side getting cooler than the other because it all gets cooled from inside.
