I can't seem to find many topics on this on SAU.

So there are 2 sides to this story that seem to play out.

1. They reduce radiant engine bay heat while increasing turbo efficiency by keeping heat in the turbine housing.

2. Can cause oil "coking" of the bearing due to keeping excess heat in/around the housing

 

Have watched a couple of vids by Engineering Explained and the like on YT, and performance wise, they seem to work well. 

Don't seem to have much real world data on the oil coking bit.

Many RB workshops run them in Aus and all over the world. Anyone have real world experiences with Turbo bearings failing due to Beanies?

P.S (i recently bought a turbo beanie and running it on a water cooled GTX3576 gen2)

Coking is not a thing on a running turbo that has cooling (ie sufficient oil and/or water flow).

Seems to be more related to when the car is shutoff as opposed to running? Opposing side to that is if the turbo is also water cooled, the water should in theory take out the excess heat anyway.. *After you've let the car cool down*

Similar to the BOV VS No BOV debate

I've always run beanies on turbo cars, never had an issue 

+1 for reduced enginge bay temps and no melted "stuff"

Coking was a thing on old only oil cooled turbos, water cooled turbos "percolate" negating this

This part I find a bit some what controversial... 

I run one, have always run them to stop things melting at the track. All my turbos have been fine, just the motors explode instead 😂

Isn't there a delta in temperature across the turbine housing? Some of that heat has to go into generating KE for the turbine no? It's probably a second order effect compared to the delta in pressure so I doubt it'll be a huge benefit for performance but it's probably not entirely make believe.

Maybe in a F1 car, but not our shit boxes to be honest.

Like GTSyoda explains, it's fark all.

I was getting concerned smelling resin from my cf bonnet, so I put a beanie on my big single, I noticed MUCH lower engine bay temps. No more resin smells.

I also noticed slightly higher ECT/Oil temps on average - By around 2-3 degrees maybe, but I do run an oil cooler so thats no issues at all.

I've just heat wrapped my downpipe and its improved underbonnet temps even further.

I still don't understand why there is seemingly so little consideration paid to heat shielding in most single turbo conversions.

Because most of these single turbo conversion guys only use it for drag racing or roll racing.

Car is on noise for like a whole 8 to 12 secs.

Put any of those cars around the GP Circuit at Eastern Creek and watch things melt.

100%. Mines already shielded on the side, all the way from the ABS down to the rail, plus i have heat reflective tape all over the body by the hot side inc firewall.

The way it should be done!

Most of these "Instagrammable" cars would ignite after one lap of a real circuit.

So, what's the goto for turbo blankets? What are you guys using? Asking as someone who hasn't looked into this much before.

You have this uncanny ability to make me worry about oddly specific things. In a good way. Yes, I'd like to go around GP Circuit at Eastern Creek and no, I don't want to watch things melt. Not that I'm running crazy power but stuff still gets hot.

I'm just using a PTP one, so far it hasn't spontaneously combusted yet lol... Has been two motors, plenty of heat, plenty of anti-lag LOL..

Truck spare parts have quality beanies

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Most of the aftermarket stuff is average or costs an arm and a leg

Beanie stops paint fading on the bonnet. But it does makes the bearing housing and turbine housing extremely hot. In cases of oil cooled only or people can't be stuffed connecting water pipes, turbos run without the beanie lasted alot longer.

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
