Yes, air filter and hydroboost cooler are in the front corner. With the headlight cracked like that you can look in and see both, so I’m hoping some air makes it in there at speed.
Alright guys, after about a month of running, a couple track days, and not that many miles, this coolant temp sensor is deader than a door nail. Has anyone experienced this problem? It’s mounted in the rear of the passenger head. I’ve ordered another one to replace the dead one. Should I shield it given how close the coolant sensor mounts to the header? Maybe put a spark plug heat shield sock around it? No idea why it would fail so soon.
FWIW - my car uses VDO sensors (oil pressure, temp, coolant temp) and gauges too. My oil temp sensor is in the block above the oil filter - behind the exhaust manifold. No problems in almost 2 years, 3-4k miles. Coolant sensor mounted in the radiator -- no problems. In fact, near as I can tell, the coolant sensor is at least 22 years old.
I guess it could have been a faulty sensor, been using VDO for years and never an issue. Anything’s possible though. A fresh one arrived today to swap in, hopefully it’s a good one. This one runs my dash guage, the one that feeds the ECU and activates the fans seems OK. If it fails again I’ve got a spot in the rad I can try next.
Ordered a new temp sensor, exact same one. Works fine (for now?). I put some fireshield hose around the sensor to keep the heat off it, hopefully it lasts longer than the previous one.
Hey, curious how you attached the throttle cable to your pedal. I picked up the universal kit from TPC. The attachment point at the throttle body was straight forward, but the pedal not so much. Looks like I might have to drill a hole in the linkage? Not sure if you have the same kit, but this one has a clevis on the pedal end.
I got my cable from TPC as well, the clevis end at the pedal sounds familiar. I definitely didn’t drill or cut anything at the gas pedal, but I can’t exactly remember what I did. I’ll get under there and take a picture for you, won’t be until later tonight though.

I've used a lot of those post style VDO sensors,, Don't let the wire hang its weight on the sensor,,
I ti-wrap the wire so there is a short loop to the sensor so vibration of the wire isn't tugging on the sensor.
Used to be a regular problem on VW buggies, people would just connect the wire and it would hang
from the firewall area to the sensor.
They are not particularly delicate from a heat perspective its just a thermistor in a potted socket,
It may actually read slightly high if over protected since one end is heat soaking from the head..

OK, snapped a picture. I made no alterations to the stock pedal arm. I may have opened up the hole on the clevis with the drill press to fit it over the stock attachment on the pedal arm (can’t remember). I slipped one clevis hole on the pedal arm, then a rubber grommet to help stop any side to side movement of the clevis, then slipped the other clevis hole on. It hasn’t moved or caused an issue since installation.
Thanks for the pic! I know how much fun it is to crawl under there, been spending a bunch of time under there myself lately. That was exactly what I needed to see.
