Scratch that. After going into matchbot and accounting for the increased CACT temp during the 5th gear portion of the pull, the air flow numbers are not any better than 4th, even though the boost is higher (that matchbot tool is really helpful). One of the many reasons why it's important to look at other parameters than just boost...

Do you have any more information on that R90 pump? Perhaps a Bosch# ?

[ASBSECU E93]

Do we have a list of shops in the US who can currently upgrade 335d stock turbos directly to the end consumer?

Both LP and HP options?

Looks like E60 pre-LCI and X3 3.0d uses a R90 pump.. That must be plug'n'play ?

I mean - I'm dropping in a LSD and doing the Solid piped FMIC and xHP flash...why stop there

Sure, then strip the interior completely, insert a roll cage, cut weight wherever possible, throw on some supersized drag slicks, and call it a day.

Don't think I won't.....and drive this sucker every day too?!?!

Are you making your own piping for the FMIC? What FMIC are you planning on running? With some small modifications it looks as if you can fit a larger one than the stepped intercooler offered. I think I may go that route to save some cost, have a larger intercooler, and be able to run a little better piping route with little larger piping. I was on another forum (I don't recall where) but someone did this with a Euro D and saw improvements in efficiency switching to different piping. Maybe a possible market for someone to make a larger/more cost efficient intercooler and piping kit. Getting rid of the stock connections would be great.

Not sure yet on the FMIC option. I have a couple weeks before I get everything back to install....so still doing research.

My friend E46 30d with factory injectors, 11 blade compressor weheel and Land Cruiser turnibne
(stock exhaust manifold and intake system).
I don't found the switch for complet asmod(temp by sensor after the cooler).
Anyone the damos for e46 204 eu4?

Thank you.

Too bad there wasn't a water to air FMIC. In my stang, I had a Whipple with a fluidyne H20/AIR

I've quoted a few comments from another thread as I think it's relevant and might create beneficial discussion here in the hybrid thread.

I remember seeing some air flow data TDIwyse posted after installing his Pro Turbo hybrids, which I believe was in the 62-65lb/ min range with his hybrid turbos but now I can't seem to find the post.

How much airflow lb/min are these modified turbos pushing to reach 475whp BPC tuned, 480BHP (WHP?) JR Tuned or TDIwyse's JR Tuned 509WHP?

It seems both full hybrid options, Pro turbo and Bohl are flowing a lot of air compared to the stock LP turbo. Do any of you know a method to approximate the air flow of these turbos or how much power they are capable of supporting? I know the hot sides are the same size (58mm) and the cold side is only slightly different in size (Bohl's compressor is slightly larger (1-2mm) at 71mm.

Is there a way to determine the max output of these turbos with the info we have? It sounds like fuel is now a limiting factor, but how much more air flow is available from these hybrids? Is there enough air flow on tap to justify spending serious money upgrading the fuel components? Or are these turbos nearing their max.

Here are the links to these two outstanding full hybrid dyno sheets.

Maybe this was what you were looking for?

This airflow question, since we are saturating the MAF and it can't read the actual flow, was the whole reason why I developed this method to be able to get a measurement on airflow: http://www.e90post.com/forums/showthread.php?t=1210979

You can also get an idea of airflow from calcuations from matchbot. But this requires you to have good logs of critical data to fill into the calculator. And you have to make some assumptions about certain parameters (like VE for example) ... but if you can measure airflow you can check your assumptions.

An example of matchbot from logged parameters on the Pro Turbo config in my specific car was posted here and was coming in at ~64-65 lb/min at peak rpms: http://www.e90post.com/forums/showpo...&postcount=466

The measurement technique outlined in the first thread I linked above, was also showing mid 60's lb/min airflow.

[335dsleeper]

Yea, bud.. that's what I was referring too. Thanks for posting, I couldn't find it.

Do you think the turbos are capable of flowing more air than the 475-510whp? Meaning, if we installed modified CP3 R90 pump and modified Bosch injectors, is there enough airflow to make any more power and to make this investment worth it? If so, how close to the limit are we... would we be looking at 1whp or 50whp increase with additional fueling? Is upgrading the fuel system the next step to making more power or will we be limited by the turbos airflow once again?!

I assume we're at the top end of these turbos, I can't imagine getting 67-68lb/min out of these hybrids.

Dash all 335d 286 has r70 railpump? The 535D 272 version is the only one has fitted with r90 from biturbo versions? Wich one is the reasonable(affordable ) choice ?
The automatic gearbox is faster than the manuel(6hp)

I can tell you at 40+ psi and the Bohl turbos, I hit a limit on the stock fuel system, could not go any higher with boost. As for air flow, from what we have seen with the larger IC setup, im sure the next step would be increase the intake piping going to the LP turbo and delete the MAF. Im sure that will free up another 15 - 25 more hp to the wheels

Bob. Assuming full deletes, intake, full exhaust, intercooler, egr block off plates, etc.

Is it possible on the stock fuel system to hit 500whp with the Bohl turbos without METH injection?

[335dsleeper]

Running without the MAF would be interesting.

No!

You're not hitting 500whp with stock fuel system without meth. Hell, many won't hit 500whp with meth.
