Turbo Porting

[sledstew]

We have had alot of calls on turbo porting and whether it works or not. The answer is yes it works extremely well, over the last year we have tried 5different styles of porting schemes and came to the conclusion that one of the 5 works way better throughout the entire powerband. The fuel equation shows the engine using 9-10% more fuel throughout the boost and active table fuel mode proving its true at the same oxygen readings.

Just some info:
Stock turbo vs Ported turbo
Stock sled 10.7 psi vs ported 8.6 psi to make the same power at 8300 rpm.
Both sleds using the same exact clutch setup and fuel,same day, same location.

Just some good info for the guy looking to get a little extra from their turbo instead of running high boost.

What elevation are you testing this at and what turbo set up? If you want to pm me that would be great!

That's significant, what size turbo did you use in the comparison? Do you work on the compressor, exhaust side, both?

You are porting the cylinders and not the turbo right?

 

[Boyko]
