S&R Performance single turbo kit?

Your right that's why the turbo is Heat Wrapped. Not saying that will stop all of the heat but that kit is proven...

Life lesson of the day. With your turbo, among other things, it's always safer to bag it

Funny thing about this is that after I put the turbo blanket on I could literally hear left over oil boiling in the turbo. I have never investigated this but it didn't sound good to me knowing that oil is going to recirculate back into the system. It caused paranoia and I changed my oil every 1500 miles..lol..

PS. Never heard that before the blanket was on.

Are you letting it cool properly prior to killing the ignition?

Just drive easy for a couple minutes before you get home.

I am. Even if i wasn't, I never heard the noise until after the turbo blanket install.

I drive really slow through my neighborhood, pretty much at idle since im on a slant, which takes a minute at least. But again, I did this same thing without the blanket and never once heard the oil boiling. As soon as i put it on I noticed it that same day.

Im not saying this is a poor kit design. I wouldn't have bought it had I felt that way. Im just saying that it plays a role in the setup.

I also had a turbo blanket on my turbine, Ive never seen one on the compressor though which is only an inch or so away from the intake pipe.

I almost cut my throttle body off and welded it to the other side of the intake plenum so that the intake pipe wouldn't sit over the turbo.

I removed my drivers side wheel well guard to get more air to pass by the turbo and get it out of the bay. This also allowed you to hear the turbo spool more which is always a bonus.

Where BP places theirs just makes a whole lot of sense to me. They also state 650+ on that setup. However, May would be the earliest for that route now.

Location aside, the big reason for the high HP rating is the option of a 67mm (935HP as rated by manufacturer) turbo with a large T4 turbine.

It is simply crucial to have a large T4 turbine on these engines, and the test result I did last year have confirmed this. IMO anything smaller than a true T4with large A/R ratio, will generate excessive exhaust back pressure (exhaust pressure between heads and turbine inlet), greatly reducing efficiency and high HP potential. The turbine becomes a huge choke point if not sized properly, and the power will simply dive. Any time you see a dyno graph where TQ is lower than max HP (or if the two are even getting close), it is a good indicator that the turbine has reached its maximum flow limit.

Remember, all that air the compressor pushes out is mixed with fuel and ignited....all this has to go through the turbine housing.
