Turbo Blanket?

Adding fuel and retarding timing will cause the fuel to burn while the exhaust valve is still open, causing it to burn in the tailpipe thus heating everything up. It's the same principle that rally cars use to spool big *** turbos with tiny engines with manual transmissions.
I've done this many times as have others. Running the engine lean will just burn up the rings and get the truck hot in staging.

I understand what you are saying, and that's fine to do on the line. I wouldn't do that while in staging though. I'm not saying running a 17.0 AFR, but a 15.3-15.5 vs a 14.7 isn't going to hurt it.

Would a turbo blanket help keep temps up so there is less lag once you get to the line? Sorry I wasn't more specific before.
We are looking at two different things.

there might be a slight performance increase if your airfilters are sucking under hood air and are able to get cooler air.

Hey Parish, ho wmuch of a decrease in underhood temps did you see with blankets? Thanks
