@Pure Turbos.

Just wanted to make sure I was understanding this correct, you are offering 2 different inlet snout sizes? Stock diameter (1.75"? and 2" machined version)? Thanks!

Yeah I think Terry's F80 slipped in that 630? range. So probably in the mid 600 range is going to be a fine line from car to car. I think the F80 would have done better if there was easy way to flash. Flash end really affects the DCT. I've had my DCT slip at 450/450 because of an improper flash.

DCT starts to slip around 550whp. I've had a couple of instances where it slipped with my M4. Sending out the clutch basket next week to get the Dodson clutch packs installed.

If I remember correctly it began to slip around 580

Patiently waiting, E85 is not around me at all. I am in need of upgrades and these could be the ones.

IMO DCT will fair better than an AT with MT probably being the strongest overall.
My 335i is both AT and DCT and it's a single car.
VIN is WBAWB72090PY13822. You can look it up.

Right now, i have the D(rive) mode, the M(anual) mode, the Sports mode (clicking the Sports button) and the Sports + S mode (Clicking the Sports button and shifting the gear to S).
Sports + S is crazily fast and I will encounter traction control by the DSC the moment I floor the pedal.

I have no opportunity to dyno the car.

You're confused. What year is your car and it is an N54 correct? Unless you have a 335is or a Z4, you don't have a DCT transmission.

I'm assuming you have a non-US 335i with 7spd DCT? They have an auto mode but that doesn't make it an an AT. Even modern ATs have a 'manual' mode where you can shift them manually, sometimes even with paddles, but they are still an automatic, not a DCT/sequential. A true AT has a torque converter. DCT has two clutch baskets as it's name implies. Comparing the two trans are like comparing apples to oranges. Even though both trans can be operated in manual and auto modes, they are very different.

DCT has multiple clutches more like clutch "packs" in 2 baskets.

That just sounds like a DCT...which is a type of AT.

Yeah just less confusing when trying to explain it to think of each basket as a clutch.

DCT is closer to a manual than AT. DCT and MTs have clutches. AT has a torque converter.

Sorry to get off topic, Pure.

AT = Automatic transmission

Does it shift its own gears? If yes then it's an automatic.

DCTs, Hydraulic Coupling types, Torque Converter types, SMGs, CVTs, and Hydramatics are all types of automatics but only one of those listed has a torque converter. Thats where the confusion in the conversation stems from. Not sure why we need to have discussion on a thread about turbos, though.

What is this thread related with ? Why does pure turbos keep away itself from the topic ? Lots of questions haven't been answered yet

Are they compatible with xi ?
What are the optimum features&specs and fueling limitiations to utilize this turbos ?
I mean what will be my gains if I replace my RBs with pure turbos? (Should be worth it though , at least with E30 and %100 methanol)
What is the max gain and safest pushing limits for stock AT ?
Can you consider a group buy for the first batch at least for ten of us ?
Thanks in advance.

Yes, they are compatible with xi.

Don't really understand your question, but the best fueling setup would be port injection with e85 or another high octane fuel.

I don't know what your gains would be if you swapped from RB's. We use larger wheels than the RB stg2, so I imagine it may flow more on the top end or with high boost.

We build turbos, not transmissions
You can find lots of AT information on N54tech. They seem to handle 550-600whp, sometimes more.

Group buy, maybe. The more people that ask, the more inclined we are to do one.

I figured that I'd understand. Thank you very much for your detailed answers. But what I am really trying to learn is; do we have to use all potential power of those turbos?
for instance; it can do 700+ with its %100 capacity through a good fueling, but 600whp with its %75, if it is dialed in well with regular pump gas which is supported by some ethanol like E30 and methanol injection. At that time , How logical swapping ? Will it hurt ?

The turbos will run very well at lower boost levels. We have a customer who switched from RB's, and he runs around 22psi. He claims: the power feels close to the same (has not dyno tested), but it seems more efficient because IAT's are lower, (his words). Which doesn't mean much with no data. Though it does sound right to me. Efficiency was critical throughout the design. I hope that helps.

Set ordered, can't wait for them to arrive.

I've had RB's and I run TFT inlets. I will be doing a 94 e10 (my best pump gas) and a custom port injection 100% meth setup hoping to run about 23-24 psi with that.

I will be able to dyno the pump only, then the meth setup hopefully soon after install.

Thank you very much for your prompt reply and detailed answer.
The next step is to make an order
