Anyone Want to Share Data Logs w/Kuro Turbo?

[Cueyo]

Ah, gotcha. That makes way more sense. lol

I agree, he has tuned multiple cars without an upgraded fuel system with what appears to be good results, which is why I found it interesting that he doesn't recommend actually doing that. My assumption is that people mod their cars how they want and then he does the best he can with whatever it is they have. I don't think he is turning anyone away just because they don't follow or know his preference or recommendations for parts.

I know finding someone with the Kuro and HPFP only would be a rare thing, but it would be cool if someone out there did do that. I know lots of people have the Kuro with the stock fuel system, it's just a matter of whether or not they will see this, actually have some data logs saved, and be willing to share them with me.

Also, here's a couple of examples of what he has said. One from a comment I made on someone else's post on Facebook, and one from an email directly from him when we first started talking about parts to use, what I was going to use the car for, etc. I forgot that his response was to using flex with 91 octane as that is what I am limited to here in AZ at the moment, but I doubt that would change once I move and have access to 93 again.

Email Quote -

"You can certainly use ethanol if you want, but you will operate on razor-thin margins for the maximum output available when confined to the stock fuel system... especially when your base fuel is ACN91 (which tends to require a richer mixture to avoid knock, taxing the system harder natively).

There's absolutely gains to be had from ethanol use instead of just the low quality 91; but I strongly suggest installing an upgraded high pressure fuel pump at the very least to make it worthwhile with the least headaches and highest level of reliability."

Did he ever respond to you about humzas @Unity Performance car in particular? Im basing a lot of my build off of the suggestions I've gotten from him in email. Interesting that Derrick said the hpfp would be the least of it given it's the most expensive part outside of a new turbo lol.

I'd honestly ask derrick if he has any logs if that's what he's suggesting.

if you want up top get RV6 turbo. The base Kuro is low/mid quick spool. Will never beat the RV6 up top. Honestly you get to 400 and want more and more lol take your time lots of hidden data our there

I appreciate the suggestion, but I'm not really interested in a bigger housing turbo. That's just going to add too much lag and from what I've seen, no turbo makes more than about 450whp on straight 93 anyways, even with all the fuel mods, so if you aren't upgrading the fuel system to run ethanol, I think there isn't any point in going past the standard Kuro or maybe Kuro+ max.

I understand the itch to do more and more as the modifying bug can get out of hand real quick. lol But it won't be a problem for me with this car. This car is made for handling and not going fast in a straight line so it's pretty pointless to chase high HP numbers anyways to me. I just want to add a "tasteful" amount of power while keeping the balance and purpose of the car intact. If I want to go fast in a straight line I would be much better off throwing boost at my 5.0 F-150. There's no amount of turbo on this car that is gonna keep up with that. lol

No, he didn't. Come to think of it, I'm not sure he's ever responded to my comments on Facebook. He's usually good about responding to emails though. I haven't asked him for data logs directly because I honestly didn't want it to come off rude or sound like I don't believe what he is telling me. Like, imagine him saying you need to upgrade the hpfp and then you say oh yeah? Prove it! lol. I also like to get more than one opinion as getting all your information from just one place for just about any subject isn't the best. If you do lots of research and gather information from multiple sources, it's easier to see things in a larger scope and make an educated decision on what's right for you, you know what I mean?

That's what I thought too about you asking him, seems kinda rude, but I also don't know him personally so don't know if he'd be cool about it. Have you reached out to @Jester04, he does a ton of these too.

And yeah fully agree.

Good concept to have!! I tell people that all the time! Can't listen to one source especially people who sell it or get paid to push it LOL and yes the truck will always beat this thing LOL I just started selling a lot of Raptor parts! I am expanding into trucks so I get it! Also If you want long term street reliability OEM style nothing wrong with looking at MHI stage 2 also.

and for the record Derick is the reason I got my HPFP when I used the KURO for a short time. He was right! Huge difference after installing and no I don't have logs I had full bolt ons with it.

I don't have logs but I have personal experience since my car has had the Kuro turbo on it for almost 10k miles with stock injectors and stock HPFP.

Your horsepower goals can be had with the stock turbo but it would be pushing the stock turbo, some may say pushing it past where long-term reliability now becomes affected negatively. I haven't upgraded the injectors and HPFP because like you I find it hard to justify the spend for the extra power especially since I'm quite happy with the way my car feels(my hasn't been dynoed).

The Kuro does need the upgraded injectors and HPFP to maximize its potential and it really is a waste of money to upgrade the stock turbo without upgrading the HPFP and injectors.

While I do not have the logs you have requested I am happy to share some input here. I do agree that the Kuro turbocharger is the best way to achieve 400WHP efficiently - doing so with the factory turbo is really just pushing it way out it's efficiency range and any turbo larger than the Kuro is going to give up more spool that desired.

Your big question is the fuel and my initial reaction was that it would probably be fine. I did consult with Derek at IMW on this on your behalf and his thoughts are that with good quality 93 octane you may be alright. With 91 octane - no chance. If your 93 octane is of poor quality, it would probably not work out.

All that being said, a HPFP is a big investment. I would definitely not blame you if you wanted to try things with the factory fuel system. If it does not work out the way you want it to, you can upgrade the high pressure pump later and start creating room for a bit of ethanol, if desired.

Thanks for your feedback. I appreciate your response but it is a little confusing. You say you have had the Kuro with stock fuel system for 10k miles and are happy with it and don't see the need to upgrade the fuel system, but then in the very next sentence you say it really does need it and is a waste to upgrade the turbo without upgrading the fuel system. So which one is it? lol

Thanks for checking, you didn't need to do that but I do appreciate it. I definitely wouldn't upgrade the turbo while I'm still stuck in a place that only has 91, I feel like that would be pointless for sure.

Oh yeah? That's cool. The trucks are no joke for sure when you start boosting them.

I agree about the MHI turbo for long term reliability as well. I was originally thinking about using that turbo on my Accord before I ended up trading it in on the FL5. But the Kuro spools a little faster and after seeing several people, including Derek, recommend it I was thinking about giving that one a shot. We'll see though. I might just end up keeping it stock turbo with just the custom tune and bolt on parts as it is.

Knowing what I know now, I would not upgrade the turbo if I had to do it over again. I believe there are better areas to spend the money especially if outright power is not your goal for the car.

Ah, gotcha. I can totally understand that.

I haven't yet but I was definitely thinking about reaching out to him if no one else had or was willing to share their data logs.
