Porting the Turbo Volute

I'm prepping the Sledgehammer electric turbo for coating - and I share with you how I ported the volute. Join our forum at www.electrifiedboost.com and consider supporting my efforts on patreon: www.patreon.com/AlexLTDLX

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!

[@AlexLTDLX]

Thanks Cody. I shipped it out today to Mark's attention... really looking forward to testing this out!

[@williamzoom]

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

[@bleach_drink_me]

Thanks for the tip of the flap wheel.

[@802Garage]

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

[@ttzfer]

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

[@AlexLTDLX]

You and me both!

[@neal6418]

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. 👍👍😄

[@c4r5on88]

I'd love to own a flow bench also to see if my DIY porting worked

[@AlexLTDLX]

Thanks for watching. There are some DIY flowbenches out there - and they're pretty accurate (my machinist built one and it was spot-on with a superflow; unfortunately, I don't remember specifics about his bench).

[@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. :)

[@Army4690]

Hi! I work here at L2L coatings. We do turbos, superchargers (rotors and housings), pistons, engine bearings, and anywhere you may want to tighten up clearances.

[@danekunderhill4812]

Nice one! Love it. New sub right here right now:) Cheers.

[@AlexLTDLX]

Awesome, thank you!

[@FixItStupid]

Thank You Good Video & TECH.

[@AlexLTDLX]

Thanks for watching!

[@boltonky]

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

[@AlexLTDLX]

I agree - no matter what, it'll be interesting! Thanks for watching and subscribing.

[@GCS88]

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

[@stevenoe6395]

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 day!!!!!!!

[@AlexLTDLX]

Thanks Steve.

[@joek4721]

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.

[@AlexLTDLX]

Yes, it is the stock cover.

[@WholesaleTurbos]

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

[@AlexLTDLX]

We did dyno test it, and I did a deep dive on the data: kzbin.info/www/bejne/amK7domwq76pidk

[@WholesaleTurbos]

@@AlexLTDLX too many variables with the data on that vid. did you pick up mph?

[@sareph69]

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.

[@AlexLTDLX]

Thanks. I did run three meth nozzles into the volute, and then we dyno tested it - it definitely picked up power. Here's the video: kzbin.info/www/bejne/mGrHZqusbq6Bo9k I had similar concerns, but not due to heat, but due to running the meth so close to 35,000 watts of electricity. If you're smart about your lines, there's a good chance you'll be fine. If you're really worried, you could make the lines near the turbo out of stainless tubing - don't use aluminum or regular steel - meth can be corrosive to both of them.

[@sareph69]

@@AlexLTDLX Thanks for the advice, I would love to run a small nozzle into mid volute. I did some research on heat shielding and sleeves and I think routing above and away from the turbski as it is rear mount then the exposed piping will be minimal.

[@tedbear631]

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.

[@AlexLTDLX]

Still very much in a development phase. I really believe there is a lot more power to be had from the right combination of parts.

[@bleach_drink_me]

How big is that impeller?

[@AlexLTDLX]

6" exducer; about 152mm.

[@bleach_drink_me]

@@AlexLTDLXmakes my 71mm turbos seem small. Impressive impeller you got there 👏

[@AlexLTDLX]

I'm sure the impeller I have spins a lot slower - speed makes up for a lot. Imagine an electric motor that makes 53hp at 1,000 rpm - it would weigh a couple hundred pounds. Now look at the motor I'm using on this electric turbo - it also makes 53 hp (we've actually seen as much as 47 hp out of it); but you can hold it in the palm of your hand. Both can do the same amount of work, they just do it differently.

[@NotSure723]

Please stop saying "Volute"...

[@AlexLTDLX]

It's pronounced differently depending on where you are in the world. I actually looked that up because your comment isn't the first on that.

@@AlexLTDLX 'compressor housing' is what most people call it.
