Upgraded turbo just arrived!

[iso100]

I don't see my post as negative, nor was that my intention, but can I ask why you expected a negative post from me?

I don't see it as negative at all. I just feel he's the most knowledgeable user/tuner we have in active participation here on the forum so I value his opinions and assertions.

Perhaps they were just worried there was something they were missing?

So is this upgrade available for purchase now? and can you clip the turbine wheel?

Soon, we're all waiting for the power results.

How about I just delete my post. I'm not looking to open a can of worms that has nothing to do with the turbo on this thread.

I will also agree that Razor is very knowledge tuner so far on these car and past cars ( a lot of us are on past cars). In fact he offered to let me use his E30 tune if I had access tuner.

And it is a reasonable question. And it was answered. If ANYONE ELSE has questions not specific to the process, specs, or sizing in numbers of this turbo, please feel free to ask. I don't want to squash any questions at all. Actually, the opposite.

But understand, I can't give away dead set answers on sizing and just how it was done.

There are lots of questions we can't answer 100%.

#1 on the list... Can the turbine shaft handle it? We've put this same sized compressor wheel in a fiat 500 Abarth turbo, and its a good amount smaller than our fiesta turbine wheel and shaft. That turbo did not surge, that turbo is still running strong and that customer is really happy. But... Its still an un-known for us. If the fiesta turbine shaft is equally as strong material, then it will have no issue at all supporting this wheel.

#2 we went conservative on the turbine blade clip. We know this will respond quickly and increase flow without adding much lag. We can clip more. Every turbo has a point... A point where clipping starts adding very bad lag while returning less gains. Rick's turbo has a nice safe clip.

#3 will the stock intake elbow work? I think it will. Will it be optimal? No. But. Gain, this turbo is focused on budget because if you wanted to spend $1800 on a turbo, then may as well goto a full on big turbo upgrade. I believe Rick will work something out. My car will prob run the stock inlet for a short time. I think Rick could maybe answer this question when he gets a chance, he has both in his hands right now, lol.

Very soon. Dyno pulls have to be made. Rick's full bolt-on car , as well as mine.

The idea i have is to show VERY "real world" repeatable results with my car. Being that I am on a budget and can't throw everything all at the car at once (because I can't afford it ), I want to show what the turbo will do for the average person on a budget that buys parts as they can afford them. So my car will be dyno'd like it is. If you don't have a TBE and a access port, then you should prob buy those as you can before buying a upgraded turbo. I will also use the cobb OTS stg3 tune un-modified. Because I want to show real world "bolt-on" and go results. After that dyno, I will have an E-tune done and dyno again.

Ricks car will hopefully show us the full potential of the turbo as an "end-game" for guys like me. It could make 240whp, it could make 300whp. I can tell you, in other applications this wheel has made 300whp. But... Not On in these housings and not on this motor, so that's why math and science only takes us so far before a car like Rick's has to be built to see

I do want to say that this stuff was not just pulled out of a hat. We have done other turbos JUST LIKE THIS, with sometimes, way better results than expected or that the math would suggest.

A quick plug, lol, if any of you guys have F-150 ecoboost trucks, we also do those turbos with awesome results. But Lets not get into that here

 

[iso100]

Can someone explain what turbine clipping is and why it's done?

I'm also interested in hearing what the technical description of surge is. I believe my XR4Ti surges but am not sure that's the word for it.

 

[iso100]

Also, I like that this is a budget option. I will be following this very closely. Of course an intercooler should be installed before going this route.

I agree with you on the intercooler. I actually wish I had gone the intercooler route first instead of the TBE route first.

That being said, I'm going to have results with the stock intercooler. Rick will have results with the big cooler

Sweet. I don't have an intercooler either. Will be great to see the results.

Turbine clipping involves taking material off the turbine blades. It reduces the amount of flow the wheel catches and lets it pass un-impeded ( or "less-impeded", lol ). It results in less back pressure in the exhaust manifold and increased power. But... Like most things automotive, it comes with a trade-off. Being the blades catch less flow, that is less flow used to turn the turbine shaft and it generally increases lag. So... Clip it too much and you get great topend and a very lazy turbo. Don't clip it or do not clip it enough, and the turbo can make too much pressure too fast or the back pressure in the exhaust will be too high (like 65psi in the exhaust and 20psi in the intake ). Its a balancing act like a cam shaft for a motor.

Big turbos (or fully upgraded aftermarket ) are normally never clipped because the turbo is matched so closely to the engine when the turbo is bought.

 

[Sourskittle]

I really want "no BS" results on my car. I don't want to wow everyone with my dyno numbers as much as i want to show a delta (wink) between the two on the same dyno that EVERYONE can expect to achieve.

I think by just looking at the turbo, (damn... It looks mean, lol ) you know its going you make more power. But i don't want to find a dyno with false or high readings and dyno my car at 255whp, then have someone by this turbo for $750 and dyno it and make 215whp.

Call my car "worst case scenario" and Ricks car "best case scenario" (no pressure Rick, lol ).

 

[rodmoe]

Well done Sir...

 

[FocusMike]

Subscribing for the results.

 

[RAAMaudio]

I just measured the inlet size on the turbo and the inlet elbow, it can be used but you will have to make a new gasket for it which is not really a big deal.

-----------------

The inlet to the turbine side that meets the manifold was ported and the outlet side of the compressor housing.

-----------------

I finished up the rear axle alignment mods today(tack welded until it get the car on the ground and verify the axle alignment is true to the front hub width, off a bit and it would cause undue scrub, turn differently left to right, etc......

Then I found the right material to make the rear caliper mounts and just called to check the status on the fronts, I can finish the rears tomorrow but the fronts have been delayed at least 10 more days then shipping

I might just have to make the fronts now as well, another days work I would rather spend doing something else.

I am getting this car on the road, period, as soon as possible!!!

 

[Sourskittle]

I knew you were busting butt on it not to post Rick, lol.

 

[Sekred]

Cool bananas guys, I applaud the effort.
I'll follow with interest, plenty of dyno numbers out there for stock and moded FiSTs to give us some idea of what this compressor wheel is good for.

 

[Hijinx]

Well I'm excited.

 

[me32]

Im glad 2 of you guys of doing this to show true bolt mods vs heavy mods for this turbo upgrade.

 

[94Gt5.0]

Well after reading one too many threads over at .org about what damn shift knob to buy, finally bit the bullet and signed up here. Excited to see the results of this vs a big turbo setup. Sour, are you the one modding these??

Lots of the knowledgeable members have migrated here. Good to see you here too.
