This may be a very stupid *** question, but I had no idea how to help a friend of mine. He's doing a rear turbo build on his WS6, similar to STS, but he wants to get it tuned by Jeremy in Tampa.

The hot side is all connected, and the cold side is all fabbed and installed, only he was going to pull and block the piping from one side of the intercooler and just slap the stock intake for the trip. It's a 5 hour drive, but is there any harm in doing this?

I had everything installed on my car at the same time, so I had no clue how to help him.

can overspin the turbo since there isn't any compressor load...not a good idea

X2.....hook it up and keep your foot out of it.

As long as he has the MAF and air filter hooked up (basically running it NA), vaccum lines disconnected from the turbo, and keeps rpms and load low (no spooling the turbo) then there should not be any issues.

It will be quite easy to overspeed the turbo. I wouldn't try if for more than a couple blocks. Certainly not for 5 hours on the highway.

^^^^I agree..... i ran my car like this for weeks till it was tuned. Just stay out of it.

He needs to unhook his wastegate also so that it vents off the pressure before the turbo. Youll overspin the turbo if you dont

i did this while testing the car before tune and then an hour drive down to get tuned with no issues FWIW on my old set-up about 4 years ago.
