Hi all,

Last week we got our own M240i for parts development. After doing some baseline runs at the dyno, we finally got to work on it. Our plans are manufacturing a stage 3 turbo and a port-injection, both to be released by late May. Stages 1 and 2 with direct replacement turbocharger will follow, no estimate time of arrival for those.

We'll keep you updated on progress!

That dyno is on a stock tune? Also why the MPH axis on the bottom. All dynos should be plotted for RPM as it yields much more info.

Are you serious?!? LOL

The turbo has a flapper just like the stock one to which the actuator connects to.

+1 on Tony in regards to Dyno

We got the car in, put it on the dyno and did a couple of fast baselines, we just did not hook the RPM clamp. But it is a stock B58 engine, so we know what the torque is.
Torque should be around 340ish @5,400 RPMs

Ok guys,

So today we have machined the manifold that arrived yesterday from the foundry. We have test fitted it and looks great, we took some pictures to share with you. Port injection is now on CAD design, we hope one month from today we will start some testing.

Amazing, thanks for sharing !

What stage is in the images you posted above...? can you post some stock turbo to upgraded for comparison sake? Very interested in these. Are they ball bearing and are they VSR balanced?

[Shorty]

That looks awesome.

Also very interested in the fuelling mods you have planned.

Looking forward to more updates.

That is stage 3, we are working on the new impeller and turbine wheel to place in the stock cartridge. VSR balanced. Non-Ball Bearing, but in June we will come up with ball-bearing. In the first post there is a comparison.

Juan,

Thank you for the fast response! Very interested in the ball bearing upgrades. I see these are master power turbos. How do these compare in terms of quality/reliability to the competition?

We chose this brand because we have used these since 2007 in all our turbo kits for many different car manufacturers. We say this by experience after using over 6000 units during this period of time. We have been in the factory located in Brazil and have a very good relationship with the company. It is an all in-house production factory to control it's high standards of quality. In fact, Master Power is the manufacturer for some Mahle turbochargers that are used in OEM well-known car makers.
Compared to other brands, the advantages are very significant. For example, with most turbo makers you can only get what they offer. There is no in-between, with Master Power we can get any turbo made according to our spec needs. Also this turbochargers all come standard with a 7 blade billet aluminum compressor wheel at no additional cost.
As we mentioned above, we found these units very reliable after using many turbos in all this time with less than 1% failures.
At the PRI show 2016 we got many customers telling us stories about how strong the turbos are after abusing them for many many years.

Interested in the results for the B58 and thank you for thoroughly explaining all that. Much appreciated!

We will hopefully get the car in the dyno today just turbo and JB4.

*Update*
This upgrade does fit the RHD vehicles!

too early for the market

How so? PURE made a stage 1 in late October last year. I asked Peter@Pure if they had plans for stage 2 and he said no. Now my friend spoke to Charles@Pure and he said stage 2 is almost complete and they aren't offering credit to stage 1 for the B58... so Pure is odd to me lately. Dinan is also working on a couple turbos with Vargas for the platform. I'm all for healthy competition.

I don't think is too soon for the platform, we have had people asking for it since we released the N55 in October last year. Also there are now BMS goodies for it and pretty soon we will have a bench tuning solution, market is growing and people will start needing a bigger turbo solution.

Any dyno figures or updates?

We got to do a road test for now, tomorrow morning we will get to do some dyno runs. We feel like the car is strong, even though on high RPMs boost gets low and it stops pulling (Map 0), we will get better fuel tomorrow and see if we can run map 2 and see what it can do!
