Cavalli Turbo......

[Juben]

I've said it before, but more than one company is working on fueling upgrades. We're still pretty early on in the life of the 2.3, so like everything else, it'll just take some time.

Wow...came back to this thread and BOOM
...lol

Going to talk to Cavali and see if I can squeeze any info out of them on this turbo....that I am allowed to share..
Supposed to be testing happening but not sure how far along they are. Excited to see numbers. Hopefully price stays under 2k for entry level stages but if gains are above the 75hp mark over bolt on gains putting the car at about 450 then I feel it's worth the price. Just have to wait and see...

They are using the stock exhaust turbine and compressor housing with their CHRA. Its a 55/56 and AM is working with it now. I should have one in the next 10 days or so. I know where its at as I am in communication with everyone involved so far. That is as much as I can say. Other than I will be testing it with a forged motor.

So If you know where its at and you plan on testing with a forged motor we can assume it is putting up some impressive numbers ;). Since it replaces OEM would I be able to keep my MAPerformance intake?

Its amazing to me how all of the other tuners, using different tuning platforms, including Livernois say there is a fueling issue with this car and your the only one saying, but not proving otherwise and on top of that you say that running E85, which requires 40% more fueling then E10 (pump gas) is also not a problem...

I also wasnt making any assumptions on what you wrote, I was reading what you wrote and took it literally as everyone else did. All I did assume was that what you wrote is what you meant.



:shrug::shrug:

Just prove to me and everyone else that what your stating is a fact and this discussion will be over.

Wow. Way to go for the throat. Not to mention on a guy who's done nothing but post every bit of data and step by step manufacturing pics for every product. And he's snowed in - figurative hands behind the back.
Maybe get a PR guy.

I don't understand the issue... There's no name calling... When every tuner said that the stock intercooler was trash but Livernois backed it, everybody expected Livernois to defend themselves and give data, which they didn't.

The same claim is being made on MAPs tuning. Every tuner says fuel is an issue and they say it's not. So, naturally they should prove themselves... Which it appears they're looking to do in the form of dyno sheets. Either MAP is wrong, or they're way better at tuning than the competition.

I thought political correctness didn't exist in TX? :shrug:

I read and interpreted the statement just as JJ did. I'm patiently waiting for results from Adam.

None of the vendors here are jerks. All are very knowledgeable and deserve respect.

For a member that's only been around a few months, it might be wise to understand all the players before telling any of them how to run their business.

The fueling issue will be more limiting with the stock turbo, as it demands more power (more fuel) at a lower RPM than a big turbo will. The fuel pump is cam driven, meaning that it can only flow x amount at y RPM. If a stock turbo is demanding 450 flywheel ft-lbs of torque at 3500 RPM, that's different than a big turbo demanding 450 flywheel ft-lbs at 4500-5000 RPM as the fuel pump has more capacity at the higher RPMs.

There are a lot more factors here, as the engine is also turning faster at higher RPMs demanding more fuel anyways, more boost, etc. But the point is that the fueling situation is complicated and we won't know all the facts until the higher RPMs are unlocked with a larger turbo.

MAPerformance is probably hitting that threshold right now at the lower RPM.

Yes, If it bolts to your stock turbo it will bolt to this one. Everyone involved is working as hard as they can to bring the highest quality products to the table.

Holy crap, somebody on here finally understands, and not only understands, but can explain it for all the other guys to understand. Thank you!

I thought it was injectors that were the limiting factor at this point, not the fuel pump? Genuine question here, I'm very curious about this engine.

No, it's a HPFP issue. Brad Gusler even said today on Facebook that they were at the limit of the fuel system with around 350whp. It's really just a matter of some solutions hitting the market. You can get a Cork Sport kit for the MZR for 300 bucks or a plethora of completely assembled pumps for 600. So this shouldn't be some monumental expense. I'm just confused how E85 is even an option.

I wonder how much overhead a new pump or internals will give us. Seems the really high horsepower builds still have port injection added on other platforms. Except maybe the BMWs where an upgraded LPFP seems to have increased overhead pretty substantially.

 

[LeonBorden]

This is why I suggested a belt driven fuel pump. You can mount two if they're ran off a serpentine belt.

 

[Impulsed7]

I would never trust a belt that could easily slip with my fueling.
