The modification I make to the shield creates a little air gap between the 3" down pipe and the shield. Without it, if the shield touches the exhaust, it becomes more of a heat conductor than heat shield... I'm sure Chris is running dilithium fuel and upsidasium exhaust parts, but for traditional 951 motors, you "shouldn't" need to wrap anything...

yeah, track motors that see full throttle 80% of the session for 45 minutes need a little extra help!
Air gap is absolutely mandatory

You should try my new E85 squirters -- it sprays a cooling stream of ethanol everywhere to keep things cool.

Not allowed to have alcohol on the track until happy hour...

BTW - trivia for the day: they make E85 with 15% gasoline in it (85% ethanol / 15% gasoline) just so it will be poisonous. E100 would be straight grain alcohol and you can make a hell of a potent punch with that (200 proof)

Yep, Some of the voodoo turbo guys are running into that issue as well. Mostly on long full throttle pulls that factory shielding isnt enough . Here are some solutions

perhaps if they made little AOS dolls and stuck pins in them....
In my experience none of the sticky heat shieling stays in place. the glue wont take the heat.

What is the secret to getting the AOS out and back in quickly with the engine in the car? Remove the intake manifold, then what else? Thanks!!

I'm pretty sure the turbo has to come out first. There's a heat shield that blocks one of the AOS bolts and I don't think it can come out any other way.

A while ago I bought a new old stock turbo discharge pipe, still with the Porsche part number sticker on it. I guess it was a very early part, as it's single skinned and therefore has larger ID . Porsche probably went to a double skinned discharge pipe to protect the plastic AOS?
