Curious to know more about the SAP delete bracket and the simulator as this is the first I have heard of either so any pics and info you can share is appreciated.

Oh its just the block off plate... I misunderstood and thought it was a bracket to hold the coolant overflow without the SAP. That bracket weighs almost as much as the SAP system IIRC.

Now that is good stuff! Does it work reliably or is it a crap shoot like O2 simulators?

Works great! Basically, when the SAP Sim is "running" you send a signal to the O2 sensors that it would expect if the SAP were actually running. When the SAP Sim "turns off" the signal returns to normal as it should. You use the SAP Power to power the Sim as well.

Well Lime Rock was a bit of a bust. I only got to drive 2 of the 4 sessions because my car was too loud. Once the sound guy figured out I knew where he was and he started moving around I was all done

I didn't even really push the car, but it DEFINITELY felt a million times better with the new suspension. Every lap I would give it a little bit more, and it would cooperate without any issue. Felt amazing. Amazing feeling quickly ended though, just as I got in a groove they kicked me out. Oh well. Obligatory pics!







P.S. A video from Watkins Glen:

That's too bad, at least the car felt good.

Too loud?! Really... What's your setup? What do you plan on doing to quiet it down?

Currently, I'm running the "Top Speed" muffler. Yes, it is obnoxiously loud - that's why I love it! For the amount of time I drive the car on the street I don't mind it at all, it provides more laughs than anything. I though it might be too loud for Lime Rock (their dB limit is only 86) and it was actually WAY too loud (96 dB). I already bought four "muffler tips" which attach to the tips on the exhaust and muffle the sound (they're about 5" long each). I'll just bring them with me and attach them when I need them. Honestly though, I don't expect any other track to have a problem with the noise.

Ah, ok. That's loud, but not "crazy" loud. Like a BW exhaust, Haha. Any sound clips with the muffler tips and without?

Well, this project has been put to the backburner a bit yet again. Just bought an E60 M5 and the E34 LeMons car just received new fuel lines and now working on the brake lines. Next event is August 17 w/ SCDA @ NHMS. Will have some updates before then.

Well, NHMS went pretty well. I dual-drove the car with one of my friends and the car ran perfect without issue. I did almost go flying into the wall on the front straight leading out of turn 12 after a Mustang in front of me dropped coolant all over the track. One second I was going straight the next I was aimed at the wall - luckily I was able to bring the car back, but it shook me up. At the end of the day my lap times were the same as when I went there in May, but I wasn't pushing the car hard at all like I was in May, so there is certainly much more left. New pads and rotors going on soon and next event is Labor Day weekend at Watkins Glen. I finished the front splitter made of Lexan and attached the Bimmerworld Dive Planes. The rear wing is going to need adjustments made to it now and a rear diffuser is going in soon. Pictures below - and one of the M5.

Very nice build! What kind of times were you running at NHMS? My uncle runs a Spec Racer Ford in SCCA there once in a while.

1:24 was my best this time and back in May. However, there is certainly much more left in the car now, so I think a 1:20 is possible if I get into a groove. I wasn't even squealing the tires this time

Nice update! Looking forward to more updates on the races. Like you said, seems like you have more to.squeeze out if the tires weren't even talking back.

Both cars are sexy!

Surely you can get it faster than that with practice! A spec Miata runs about a 1:20 around there if you were running the oval in 1 and 2! It's hard to get used to the speeds involved and the braking distances

Subbed for inspiration. Great car man.

updates?

Unfortunately, no updates to this project. To be honest, the car has just been sitting for the last two months. Too busy working on the LeMons car which we finally finished up Friday night before the event. The weekend went really well, save a belt snapping and a tie rod assembly nut backing off. At the end of the day we ended in 55th of about 120 cars, finished the race (with next to no fuel left), and I ran the 12th fastest lap of all the teams. I also passed Will Turner in his Sweetish Fish car, who passed me back, and then proceeded to launch a caliper bracket at my windshield after the left rear caliper exploded. He went off track but fortunately was OK. For the first time for our team, and considering that none of us had actual race experience, I am very happy with how it went. Next year, with a few minor tweaks, an actual strategy, and no belts snapping, I think we have a damn good shot of winning it. Plus, it looks great!

Heater core is out! And so is pretty much everything else on the inside of the car. I have a spare body wiring harness I'm beginning to disect to reduce weight, already down to 51.2lbs from 52.8! May also do engine wiring harness but we'll see. Starting to clean up the engine bay a little further as well. I haven't actually weighed anything yet, but based on what I know I think I've pulled about 125lbs by now, brining us down to right around 2875lbs. 2700 is not far off! That combined with power mods (should bring us to 375hp+ crank), and this car will be a lot of fun!

Got some more work done today, and lots of things ordered over the last few weeks. The car is up on jack stands, brakes are completely off, the exhaust is out, my custom Lexan quarter window fit so I'm making the other side now, etc. Now I need to take apart the whole front of the car, drop the front and rear subframes, pull the diff, driveshaft, etc. and pull the wiring harness. There won't be much left.
