This is what is written in the Horsepower In a Box website on the turbo bags:

As these Blankets are designed to retain heat within the turbo, it may be benificial that the blanket be removed for vehicle "Garaging" as retaining the heat without the water/oil circulation may cause long term reduced life for the turbo (this is particularly relevant when used with non-water cooled plain bearing units). Although there is no documented analysis to support this theory... (we don't beleive this to be the case based on our testing and analysis)

I personally don't see how the turbo would warp, they're designed to run at high temperatures, and if anything the slower cool down would be of benefit. In any racing application I'd be doing cool down laps, and then leave the engine running to keep oil and water to circulate for quite a qhile.

I dont think they warp as such, but the machined faces that seal on the manifold etc can usually do with a skim after years of life as after uber heat cycles some have trouble sealing against gasket faces. So a metal rule on the face of the turbo flange will give you an idea of how many cycles the thing has had and whether the faces is still true. My current TD06 8cm housing was machined when it was last removed because it had 'bowed' (for want of a better term) a little

      Duncan's V37.......race car?

      That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together

      I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain.

      OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.

      Yeah that looks like great caster, but I'd suggest trying less front camber some time and seeing if it helps with braking without reducing mid corner speed too much

      I ended up setting the rear 5mm higher than normal to give some clearance.  My plan is to run the least camber I can in the rear which I think with the extra width is going to need to be -1.75 to -2.00° just to get clearance.  Guards have been rolled and pulled as much as they can/I would be wanting to.  front has the Acostal knuckle with the KPI change and the drop etc. So should be okay with the existing settings I have run with AR1s etc Front: Toe total -2mm(1mm out each side) Caster +7.5° Camber -3.8° Ackerman +15°
