Very informative. I would even be interested in a longer video elaborating more on the tuning window

[@TurbosmartHQ]

We'll look into that for you, great idea! Basically, When we refer to the 'Tuning Window', we're talking about the difference in available performance at low boost versus high boost. To explain an overly simplistic example; If your 3000HP Pro Mod Drag Car can't use more than 300HP on launch due to grip levels or chassis, you will need to bypass 2700HP & this will need a much larger gate, with good manifold priority. A smaller gate may happily allow you to dial in you top end HP target, but if you're trying to get down to lower levels for whatever reason (Drive ability, launch control, valet mode, etc) you will need a larger gate for the extra bypass requirements. The most often overlooked requirement is running in a new motor... Often the manifold & gate is chosen for the HP, but the requirements for a low boost run in tune are ignored until its too late!

​@@TurbosmartHQso a larger wastegate gives a larger option, as in it can do both high and low, is there any drawbacks in choosing a big wastegate or would it be better in general?

[@thisjustanother]

i only had the one selection for my 2016wrx with the killerB header. so it was easy for me. but thank you for this very informative video for others

Just bought the 50mm gate for my GTX3584RS Which is a 67mm turbo , on e85 on a barra should be perfect

4:00 when you talk about compressor wheel diameter, you're talking about the upper smaller or the lower larger diameter of the compressor wheel?

Great video, thanks 😎

Would a Gen V Hypergate 45 external wastegate be fine for a 13B rotary with a turbo borgwarner S362 sxe (68mm turbine)? Thanks for the video!

[@kpgsx]

For a 5.5L v8, with a single s475.....T6 1.32 twin scroll. Would a single 46mm suffice for 8-20psi control? Or 2 40mm's ??

[@Wilson_Racing]

So let me throw my scenario out there since I didnt see you list it. Decently built 5.3L with a 88mm turbo. Would a 50mm BOV and 50mm wastegate with CO2 work well? The wastegate would have good priority and the Turbo is a T6 with a 1.09 A/R housing

[@MotorsportPowercom]

2.5L 8v + G35-1050 is ok with 2 40mm compgate ?

[@bopbus4.252]

What would you recommend for a tb42efi running a gt3582r, will be running in between 10-12psi, would prefer to have it a 2 bolt flange as that’s what’s currently on the bottom of my exhaust manifold

[@shawnforbes6495]

why would you get such a large turbo to only run it at 10 - 12 psi. theres no point havning such a large turbo

[@carlosmurjal]

Which External wastegate size do you recommend for an EFR 7163 , Subaru strocker 2360 cc and target boost around 26psi?

[@TurbosmartHQ]

Check out our Product Advisor, on our website. You'll need some info on your setup (target power, max RPM, turbo info etc) and it will give you our best estimate! www.turbosmart.com/product-advisor/

[@SYLRMS]

im running a GTX3582R gen 2 turbo 66mm - planning to run a 6 boost high mount manifold should i run a 50mm waste or 45mm? planning to run 15-20 psi

[@TurbosmartHQ]

You can try out our Product Advisor found on Turbosmart.com for product recommendations based on the multiple variables of your application!

[@shizukesajdm]

This video suggests a 50mm WG for a six cylinder, but the product advisor suggests a 60mm. 2JZ NA-T, 350hp, single G25-550. What's the right path to take here? Thanks.

[@TurbosmartHQ]

Our product advisor tends to recommend products on the safer side. In this situation, we personally think the 60mm is far too large for that setup and possibly even the 50mm. You would likely be fine with our GenV HyperGate45 at that horsepower level.

[@shizukesajdm]

@@TurbosmartHQ Thank you for the response! ❤️

[@XFOX1996]

But what are the real dissedvatages of running a to big waste gate? All the explenations in this video make the bigger ones seme like the better option

[@TurbosmartHQ]

Basically, the bigger will always give you the widest possible tuning window. The only real problem with running a larger gate than you need is technically the boost control 'resolution' when the gate physically opens off the seat. This in 99.9% of cases however is easily compensated for by any decent boost controller, including a simple mechanical boost-tee.

[@heathholland5792]

I have a ar.70 turbo on my 4l falcon using it just for burnouts what would you recommend

[@TurbosmartHQ]

There is a lot more to it than just your AR housing even if it for killing tires. Reach out to the Turbosmart Tech Support Team of your region for further assistance!

Could you please tell me the best wastegate size for rb26 with garrett g35-900 🙏🏻please reply to me as soon as possible

[@3ltrchris]

Go for a 50mm wastegate, for ultimate power and reliability fit a 2JZGTE lol.

[@codydillenbeck4443]

Would a 38mm be too small for a gtx3576r single scroll .82/84 (cant remember) housing with a power goal of roughly 500-550bhp? It's on a 2.8 litre v6 on a 2007 saab 9-3 Aero.

[@dragalochta4531]

Snap... saab brought me here too.

[@TurbosmartHQ]

It's not the High End HP target that will dictate the gate you need - It's the low power target... So you tell us, how much of a 'tuning window' are you after? And keep in mind this is even more important if you ever need a low-boost run in tune. etc. In any case, you can visit our product advisor now live on the website which will tell you which gate we recomend. You'll need to enter the variables of your build & we'll tell you which products you'll need! www.turbosmart.com/product-advisor/

Can I use a 76mm turbo with a 45mm wastegate?
