Thought I'd share my experience over the weekend here.
We started with a '93 1.6. The owner ripped apart the wiring harness, enough that he called me in to get it running again. About the same time an '03 VVT auto engine was being sold with the softer AWR mounts and entire engine harness for...$1200? Something like that. It was picked up and the swap began. We found a full chassis and charge harness for ~$250 from treasure coast(?), resealed the oil pan, bolted on a 949 light weight flywheel, OEM clutch, and 5-speed tranny. Currently still using a 1.6 open diff
After jumping the auto engine harness to the manual chassis harness, we plugged the switch blade key and ignition from my '05 MSM part out into the harness and it fired up beautifully on our 01-05 MSPNPpro. We've hooked up ZERO features, but it's running great, made 135hp and 125ft/lbs on the dyno. We also have stock 1.6 brakes with no ducts, bilsteins with 7" springs, and no aero.
This weekend was our first outing, pictures are unfortunately few and far between. Check out World Racing League's Facebook page for more pictures. The weekend was also combined with Lucky Dog Racing, they may or may not have some pics of us on their facebook page.
Our team consisted of 3 drivers and myself, as crew chief. GreddyGalant (Martin) was our hotshoe driver, with massive amounts of driving experience in his 1.6 miata, now 250hp, CSTG built, MSM swapped, MCS Miata, Laz. Him and his car have come a long way, it was great to have him. Car owner Mitch, who has a lot of racing experience behind the wheel of his friend's Mustang enduro car. Then Phil. He doesn't talk much, so I won't either. Something about him designing the Saleen S7?
Saturday was the first of two 8 hour enduro races, starting at 9am. That part becomes important later. When we fired the car up to warm it up 10 minutes before the checkered flag, we noticed on our tablet (thank you EFI Analytics bluetooth adapter), that we were charging at 20v on our "new" Baxtard's alternator. Uh, not good. Luckily I had the spare NB alternator from the above mentioned '05 MSM, and we yanked the old new out, and put the new old one in. Also managed to pierce the radiator in our rush. Doh!
Luckily a certain CSTG owned NB was sitting in the parking lot.
21 minutes later, we were on track. We had a great start, with our pitstops working fairly well. We need faster jugs! We were only half way through our 2nd 5-gallon jug when the driver swap was finished. So the 2 drivers could swap belts, comms, window net, steering wheel, all before we could even get ~7 gallons in. The meant fuel was the deciding factor for our pit stop time, and you can't touch ANYTHING but driver swap while the fuel cap is open. So we couldn't wash the window, check the tire pressure, clear the radiator opening, nothing. Definitely something to work on.
6 hours and ~9 minutes later, our 3rd driver came in with a slipping clutch. The racing was over, the day was not. While one person drove 1.5 hours south to pick up a replacement, Martin and I dropped the tranny. Not too hard on a race car. The heat was killer, 80+ degrees, laying on the asphalt.
We were over shifting the car, using 2nd when only 3rd and 4th were necessary. We also found out on day 2 that our 3rd driver Phil was getting on the gas too soon, and slipping the clutch.
Start of day 2, gridded up at 8am, in 2nd:
This is ~1 hour into the race, remember, we started an hour earlier guys...
This is us, 40 minutes in, we're "What's a Miatau".
We're P7 over all, P3 in our league.
Here we are with only 14 minutes to go. A cracked header took out an incredibly fast (2:02 vs. our 2:10 laps) Miata, and our main rivals 3PG...not sure what happened to them. Some mechanical issues IIRC.
And the final shot, 209 laps of The Ridge Motorsports Park later, we told Martin to unleash the Red Mist. Hence the fast lap on our last lap.
And the result:
That's all I have for now, GoPro footage should be up soon.
To Do List, in no particular order:
1. Hood vent
3. 1.8 brakes, ducts, and Cobalt pads all around
4. More lows - new suspension? shorter springs?
5. New tires will be stickier. Yokos AD08s most likely
6. Simple aero to start. Ebay GV lip, duck tail
7. Weight savings. Engine swap and MS put us in GP2. The GP3 Miata was running 8 seconds a lap faster than us. We're at the heavy end of GP2.
8. Faster fuel jugs - ordered
9. Install the Mobius Sled's bigger NB gas tank
10. Tune for better gas mileage. We could barely make it 1.5 hours. Pathetic on my part.
