Just finished installing my PTP blanket this week. I need to go for a sprinted hour drive this weekend to compare my infrared temp readings that I took preinstall, so we can actually see the difference in engine bay temps.

So far, so good, and highly recommend to everyone. Also seems like a good way to reduce the amount of heat getting to the expansion tank, therefore hopefully extending the life.

I wonder if there are any cons to installing these heat blankets.

Also we’re any modifications necessary? Were you able to reinstall all original parts and hardware after the blanket is in place?

Some say blanketing or wrapping cats is not good. Some say retaining heat in the Vee is not good by just throwing a blanket on top of everything hot. This blanket will reduce heat escaping upwards towards the coolant tank if that is the goal. My recommendation is turbine blankets or coating and catless downpipe coating or wrapping.

[Maverik259]

Agree. Catless is ideal. Designing them to sit almost in the V itself is a rather piss poor design for engine parts longevity. Quick way to get them heated for emissions though. Fml.

I don’t know whether putting the turbos in the Vee was for emissions or for response or for engine compartment packaging. It certainly took a lot of work to change the exhaust parts on the heads from outside to inside and make a compact new crossover manifold and design new intake manifolds for the outside. Was this all to heat up the cats as quickly as possible? It sure was good for response and power.

I agree the heat will likely have a long term negative effect on the motor. I did what I could to reduce that early on the life of my motor. I did not buy an $8k Supersprint manifold and send it out for coating but if I build a motor, I would consider that.

How difficult was the install? Do bolt holes line up?

Hi Mate,
What’s this super sprint manifold, have you got a link ?

My BMW tech did it for me. He said it was relatively easy. The most difficult part was removing and setting aside the coolant tanks and hoses. He said 2 of the bolts lined up but the shear space (or the lack there of) is holding that blanket well in place. Its not moving what so ever.

I don’t think they purely did it for emissions. And Definitely agree reduction of turbo lag was a large part of it. Just stating it was a bonus for them and the European emission frogs. I truly hate sacrificing vehicle design and performance for 1 or 2 mpg so they can bank points. The lack of storage in the back of suvs so they can be more aerodynamic is infuriating. I much rather have more space to load crap when I need to than that extra mpg that I’ll Never see anyway because I drive like a maniac!

Any updates on the infrared readings post install??

Sorry I have been delaying. Allow me to work on that this weekend. Its been triple digits the last 2 weeks in northern cali.

Ill take a nice drive this weekend then take temp readings.

Overall first impressions are fantastic!

PTP is the hands down best blanket

That's great to hear. I'm having mine done ASAP

Thanks for doing this!!

It's 110-109 all weekend. Sorry I am just waiting for a cooler day. I took my initial readings on an 82 degree day. Just hoping to test in similar conditions. Its been so hot lately!

[Kponti]

Just had mine installed. I didn't do a temp check before and after unfortunately, timing just didn't work.
To set the stage, we have had 99-103 degrees the past month daily. Heat index is 113-120 degrees daily.

My observations for the past day.....the car only went to 210 degrees for less than 10 mins of the hour and half driving around and idling around I did in 100 plus degree sunny weather

This thing works, and works really really well!

I would not have expected the PTP blanket draped over the turbines and cats to lower engine oil or coolant temperatures. Seems like it is just trapping heat in the Vee of the engine. The expected benefit is lower under hood temperature, which would extend the life of plastic parts, especially those next to or above the turbos and cats.

On a car with a big, slow turbo, trapping heat in the turbine can help performance. Our little GT22 are probably too small and already so fast spooling that there would be no performance gain.

I was not really expecting performance gains with this even though I have measured almost half a second reduction in 0-60mph on two occasions yesterday.
But I definitely can see the temp gauge staying in the 160-180F range all day yesterday when ambient temps were 100-105 with heat index of 113-120F.
It will creep up to 210 if idle too long especially after a brisk higher rpm drive.
Even that is short lived, dropped temps back down a few minutes later.

About the drop in 0-60, was not expected. But my best 0-60 has been a 3.85 on this heat (tried it twice just for testing purposes). Best with the blanket is 3.41 and the difference was from heat soak. All times brake boosting not using launch control

Sorry but Makes no sense. Your engine shouldn’t experience heat soak on an initial 0-60 unless you did those times after pushing the car. The turbo blankets are not knocking a half second off your time. It’s more than likely your foot/traction.

What temp are you looking at oil temps?

I was idling and driving around quite a bit fully warmed up before making the runs
No traction issues, but I did make sure the car was fully heatsoaked from day to day driving before making the runs

How are you determining “heat soaked”
