Why is Turbo Speed Important? Testing Garrett's New G-Smart Module

[@Clobercow1]

When I want to know how something works from someone who REALLY knows how it works, I come here. Epic channel!

[@noelrabey8744]

Right on!

Nah go watch donut media 😂😂

[@muasboy]

Hi Mike. Just wanted to say that I’m reading your book - Honda/Acura Engine Performance. My brother bought your book roughly 20yrs ago. And I just recently found it. A very fun read. Thanks for always sharing and teaching us

[@Twobarpsi]

I always learn something, from watching your videos Mike!

[@noelrabey8744]

Just love your series of videos Mike. So interesting. Please keep it up. Cheers, Noel

[@MattsRbs]

Super cool! Never realized how much info you can gather just from turbo speed. I need to upgrade to a Garrett!! Thanks Mike!!

[@HeidiFegles]

The g series turbo will destroy itself if over spun. For example. 37-38 psi on a Subaru g25-660.72 ar the guy blew 3 up before Garrett said in the analysis. Over spooled turbo, so 4th turbo 32 psi. No issues, max shaft speed is 165,000 rpm. It says it in giant red warning letters in the instructions. Keep the turbo in the efficiency range and be happy. Or if your not get a bigger or smaller turbo to suit your needs. Don’t push these to the limit you will have nothing but failure. But keep it within the efficiency range. It’s a great fast spooling turbo.

Yes, you can look at the compressor map and easily know that!

[@mullins6429]

Thanks Mike, very interesting and informative video. 👍

[@doubletee4391]

I like the ducting in the front of that evo

[@RadDadisRad]

Good stuff Mike, glad to see a kit on the market to cover this.

[@BrycenKauai]

Do you think that with software/sensors like these in conjunction with electronic wastegates and the proliferation of more affordable engine management software that (street) builders should start to prioritize this over more traditional upgrade paths when upgrading from a factory turbo? For instance swapping intake manifolds, or exchanging a log style exhaust for a tubular one?

[@motoiq]

yes

[@tan-lap9128]

Great vid! I would like to know how wheel weight affects performance if you could.

[@suprakillavr4]

Would be neat if it also graphically plotted your position on the compressor map. It has the PR and speed input, just needs MAF or RPM input really. Not sure it's worth $650 to me personally to know my compressor speed when I run such low boost at 20 psi, but neat I guess?

[@moisesr7840]

I'm with you

[@aleknive]

What is that flexible pipe for? Is it to redirect air from the front to cool turbo exhaust down? I am really curious about that piping.

[@motoiq]

cool the wastegate

[@omgness1234]

Sir please help me setup my evo x suspension!

[@ShoshinMizu]

can i have it on my phone AND my haltech?

[@motoiq]

yes it has a CAN out

[@ShoshinMizu]

@@motoiq woooo thanks

[@adrianguzmanmolina]

Niiiice!

Hi Mike.

Basically your tuner should have a turbo shaft speed sensor so they don’t exceed the rpm of the turbo and destroy it. Also see the limit of the turbo. But once tuned it should be good. And for the price of them. It’s un real. I’d love a speed sensor hack that I could diy . But calibrating it….

[@motoiq]

Just get this, it's cheap.

[@HeidiFegles]

@@motoiq compared to replacing 3 turbos yes it’s very cheap and a great health tool for your turbo as well. I have never had the luxury of having a turbo shaft speed sensor on every vehicle I tune but the ones I do tune that have one installed makes seeing when the turbo is in its efficiency range a lot easier and over-spooling the turbo doesn’t happen anymore. But for those not tuning their car probably don’t need one as bad as the tuner who is wanting to push the limits.

[@nooneisrightallthetime-zv7hs]

Bluetooth should of been utilised like this a long time ago

[@nick66333]

Nissan has this a while now

[@motoiq]

Not in any production car.

[@motoiq]

you are correct and I was wrong.

[@MrSnakedoctor85]

It's in the new Z.​@@motoiq

[@Clobercow1]

I bet you can use something like this: With an atmosphere pressure sensor, and set a curve of target boost pressure that corresponds to ambient air pressure. So you get a nice curve for altitude automatically to save the turbo. That would be worth something on these engines that cost hundreds? of thousands of dollars. Holy shit let me patent this.

[@motoiq]

I mean that's old news.

[@pepeshopping]

Not really “innovative” when all the parts, and knowledge, do exist already, of the shelf and on the Internet. Somebody simply needed to put it together and package it. If this was 7+ years ago, it would have been innovative for sure.

[@RadDadisRad]

A standalone high speed counter is expensive to integrate. Standalones offer HSC counter modules but you have all the input cost getting to that. A standalone HSC that has a HIM drives cost down because now it doesn’t require a special computer. The computations are done inside the box and relayed real time.

[@motoiq]

when no one else has done it on a consumer level, it is innovative.

[@omg_stoppit]

@@motoiq Agreed. That guy can go kick a sack of rocks. How pray tell was the technology from "7+ years ago" innovative when the tech was all but alien to Joe Regular? And if the tech existed, why haven't more people adopted the tech to monitor their turbo speeds? Logically, if the tech existed and there was market demand, we would have seen consumer pick-up. The reality is no one has been installing turbo speed monitors but for teams that had the resources to do so. With this, Joe Regular can toss it on their tuned Golf R in a few hours on their day off and accurately monitor the speed of their turbo. THAT is innovative.
