Porting the Turbo Volute

[Army]

Alex, Cody here from L2L coatings. Thank you for the awesome video. I will include my buisness card when we send your turbo back and if you have ANY questions, feel free to reach out!

Never used that company's coatings but have used a competitor for over 10 years on various engine & driveline components & the stuff works!

Another great video Alex. Very interesting. Can't wait to see the results as usual.

Will def be interesting to see if you can measure the gains.

[garagecedric]

The coating normally should result in 1-2 percentage points of efficiency, it works well. Didnt know it was available for regular DIYers though. :)

Cool beans !
Yes I'm a "car" guy and try to absorb as much info on port design and modifications as I can. Oh how I long for a flow bench. Thanks for this bit of tech. 👍👍😄

Is that the stock cover? I'm aware that s/c compressors are very low trim in order to create good boost with minimal rpms. But that setup has almost 0 diffuser area, that's what does alot of the "compressing", and it's a very important part for efficiency.

All I can say for certainty is I want a sledgehammer for my car and just please if you sell these eventually don't follow the standard car trends of charging people outrageous sums of money for one. It's already enough of a pain just installing things like this for any non turbo car.

Ihi did this on their VF series turbos about 20 years ago on their vf34. From memory it was a Teflon based coating and was only on the radius which is where the compression occurs on a turbo. Since your compressor is more like a centrifugal supercharger doing the volume makes sense. But the boost you're running may not see any real gains, maybe single digit

Be interested to see how much the coating increases efficiency and how close the tolerances are once its done. I have done a couple of different coatings over the years testing intakes etc on Quad bikes and such and found it can provide such a range of results depending on thickness, how smooth it is, what the coating is made from or is. That even if it doesn't do whats expected it will provide results :)
Thanks for you time

I may have found a really cheep toyota turbo im thinki g of trying something similar to what you built. I have 4 19v motors from a hover board and a set of hover skattes going to try a chain drive or gear drive with them dobt no how well it will work but eventually ill b able to aford to build sonthing better later on. Thanks again for another great video can't wait to c that thing on the dino again with a better torqconverter that wont slipp so much have a good

The Ko3-29 is so cute 😁done anything to it?

Hey Alex, great vid, I have been searching online for info on porting and polishing the volute. I have considered running a meth nozzle to the volute, a tiny one say 62cc nozzle as it is a small K04 turbo. But a little concerned of running meth so close to such a heat source. What are your thoughts? I already have a single nozzle meth kit was just thinking of adding a 2nd one.

Please stop saying "Volute"...
