A diverter is the same as a bypass valve - bpv

@@stratifiedauto sure but where does it divert/bypass to, exactly? (Maybe you mentioned this and I missed it?)

But is engineered to work well in that area and has a big surface area. For most cars this works well.

@@stratifiedauto thanks!

If you have e85 you can blend it with premium fuel to get e30.

Turbo cars always have this built in headroom for gains, it’s great.

Didn’t test this on this car. You have to be pretty violent with the launch.

It’s a great car to keep around and mod as you can. We just put an is38 on ours. Expect a video soon :)

These particular headers unfortunately are discontinued.

No check engine lights after the tune is flashed.

It will make 30-32psi

Sounds like a fun school!

The length we got is 2 feet.

This mk6 makes mid 300whp on pump gas and upper 300s on ethanol blend. The in tank pump is not a limiting factor on that power, the turbo is.

@@stratifiedauto k04 or Hybrid?

Thank you!

We could use hptuners if you bring the car in for a dyno tune in person.

​@@stratifiedauto thank you for your prompt response. I am all the way out on the east coast so in person would not be easy. is remote tuning an option?

Coop in aldergrove and north side petroleum by braid station.

We don’t have the EFI kits on our site. At least not yet. Working on a complete engine management system for the air cooled cars but for now we calibrate them and can get you parts if you’re local to us.

You would need to also purchase the protune here www.stratifiedauto.com/index.php?main_page=product_info&cPath=332_209_219&products_id=679

Thank you!

On the intake cam

Optimizing the tune for ethanol is setting up appropriate fueling, timing and boost levels for the fuel used. Are you tuning your GR?

@@stratifiedauto I’m tuning a different platform. Changed from 93 Oct and low boost to Full E85 and same boost level. I adjusted the 30%+ fuel difference and increased timing slightly on the entire map. But then had to reduce in the low rpms due to researching the burn rate of e85 and low rpms. Just curious if you saw that during your tuning with timing.

Generally not the case. I would do your testing on a dyno with appropriate instrumentation.

The right time to tune and modify a car is different for everyone. Warranty does eventually expire and I don’t see how modifying the car should affect the oil change package. The only question there is if you wanted to keep running the oil they are offering as part of it. OEM spec oil is quite thin for track use for example.

Yes the stock tune even has some room. But of course not as much as with running a tune made for it n

It is the 525 pump. The 450 and 535 fit the same.

@@stratifiedauto thanks

We will be covering what the modifications add as we add them. So far we covered the intake, fuel octane (ethanol) and of course the most important bit - tuning.

Yup octane booster works!

You won’t gain more power going full e85

@@stratifiedauto thank you! Would just a hpfp on a gti be able to support e45/e50 with a pmax? Or is mpi necessary? I have seen e30 with pmax on hpfp alone.

E50 is pushing it. Especially on GTI where the injectors are smaller than an R by 10%. If you want to stick to DI alone consider R injectors. www.stratifiedauto.com/index.php?main_page=product_info&cPath=332_240_298&products_id=1126

There is always more with more mods.

We show that in the video.

Thank you!

It is. Tuned and if you have with some e85 it’s so lively and fun. Let me know if we can help you out with the tuning.

It depends on how good your pump gas is but it definitely won’t hurt. Especially in hot weather or on track.

We have a lot more coming. An intake is great to open up the top end. Tuning ties it all together :).

For the tune absolutely. Our car is stock hardware wise. Here is the link. www.stratifiedauto.com/index.php?main_page=product_info&cPath=358&products_id=1160

Looking forward to working with you!

Very safe. This is why we put the car through so many paces. From track to dyno to daily.

@@stratifiedauto nice I wish you guys were in my area to tune my GR Corolla.

We tune the vast majority of cars remotely. This is why we build up our knowledge on our own development car. Here’s the link.

What octane fuel are you running? 91 or 93 Also does it have 10% ethanol?

I know right … tolerances are just getting tighter.

We have another track day in July. Hoping for warmer weather. We will also have more power and more grip.

Ran mine hard for 5 - 20 min HPDE2 sessions at Sonoma last month 80 degree day. No heat shield and had no over heating issues. Car ran great and consistent all day. Tires and brakes took a beating. Can’t wait to get back out there. This car is more capable than my previous 19 STI.

Was this on the OEM tires and pads?

The tune has pressure ratio limits that are closely monitored and this is a big part of it.

I suspect it’s from a compressor longevity thing. My Abarth’s ecu models this stuff and after I raised the limits and with racing…my turbine housing cracked in 3 places, and wore out the bushings which caused the turbo to push oil. My new turbo has fixed a lot of unclear problems. So that melted turbo was too tired to push anymore and it really hurt performance. Btw, the blades were perfect.

Turbine housing cracking and exhaust heat sounds like a thermal or exhaust back pressure issue.

It can be very useful for modeling turbo speed and compressor outlet temperature for example,so the engine can derate if anything is going over the limit.

Yes. And keeps a constant eye on the actual pressure ratio, instead of relying on a model with a lookup table. If your filter gets clogged or has a hole in it, you will still be running the turbo at the same pressure ratio. Specially with a variable airbox like this one where the pressure drop across the intake system wont be the same with the flap open/closed. Probably not worth it for an OEM cost-wise for most applications compared to a modern ECU where everything like that its modelled, but very nice, specially when tuning them.

The sensor is internal. I am just wrapping the external body of the sensor that is exposed to external radiant heat from the exhaust

@@stratifiedauto Got it, thank you!

In most ECUs there are heatsoak algorithms applied, so you might be right. There is cooldown hysterisis that is modeled and the sensor gets an offset applied to it.

​@@BrodeyDoverosx Right. And I am trying to figure out if the fire sleeve is mitigating false positives or actually inviting false negatives, thereby not allowing the diff to know it is legitimately overheating and then ends up shattering because the sensor was numbed/dulled due to the fire sleeve being present.

The thermal issue is not the actual differential. It is the clutch pack that always slips to some degree since the rear end is spinning a bit faster than the front. So it’s a clutch pack longevity issue rather than a differential issue. It’s also tied into oil maintenance intervals. I recommend changing the fluid more often when racing or doing lots of track work.

White is a hard paint to match. The magic is the driving experience.

It’s an excellent choice. The tune we built for the car on pump gas and those parts is both reliable and offers a worthwhile power bump.

Keep in mind that this is on a Mustang that reads low and on a high ethanol mix. They both take away fueling headroom.

The surface is not designed to hold a gasket like that and will likely leak.

It should spool earlier than that if the tune and wastegate are setup correctly. Let me know if we can help. Www.stratifiedauto.com

They are an excellent platform to modify and build upon.
