Will there be a version for us NA folks?

[epiphone3]

one could hope... especially for guys who are wanting to convert Canadian 323i cars to Eurospec 325s. Also, for those wanting to make a 328i into a euro 330i (or 3.0si) 262hp spect... all they would need is the intake manifold from a 3-stage car and the SharkInjector and bango! Same deal for US 325i guys... could make things very easy and cheap to upgrade those cars!

Plus, it would be a good way to get a good tune should you decide to buy headers or higher flow exhaust manifolds with metallic cats.

[BzsBimmer]

Yeah I would imagine that there would be some demand since not all cars BMW makes are FI.
There are other huge markets out there that still use the NA N54 motor.
The other chips or tunes other vendors have claimed never seem to be actual long term gains with the ECU adaptations. I would think that even the 335 ECU would have the same theoretical adaptations to overcome so if a solution could be found for them, one should be found for us.

I know that conforti has had a shark injector for just about every previous NA BMW so I would *assume* that the 325/328 would be no different.

wow this is seriously nice...so the gain would be around 30hp??

...if you got the tune AND a 3-stage intake manifold.

[BzsBimmer]

I dunno
I don't think that you'd have to necessarily switch out the intake manifold. Sure you'd gain some more HP if you did but I think that with the stock innards, you'd just be able to add the shark meat to it and get some decent gains.

I know that there were some rumblings in the past about the intake and ECU map being the main differences between the 325/330 but I would also think that with just a tune, we should be able to extract HP either way.

"just a tune" gets no real peak horsepower gains on the E90 325i, but did make some appreciable gains in the midrange... something like 19hp at 4000 rpm or so. You definately need the 3-stage intake to get the high-end gains and to further boost the low and mid-range gains.

I would assume it might be similar on the 328i.

I'd be in for one... turner does make one as well for the 325i's but I'm not sure how or even IF it would work on a 328.

Turn your 325i into a 330i ! Stage 3 is for the 325i only and adds a new free-flowing intake manifold to the high-flow catalytic converters and performance software. The intake manifold is very easy to install as the factory wiring harness will accept the new manifold with just a few clicks. The new manifold has a 3-stage inlet design instead of the stock 325's single-stage. The extra stages (or flaps inside the manifold) open at differing degrees depending on throttle position and the mapping set by the ECU. The intake air has a much more direct path into the cylinders and the extra flaps also help to increase torque at all rpm. Stage 3 is where the big horsepower numbers come from: 50hp and 38 ft-lbs!



Removal of the exhaust manifolds is relatively simple and the new manifolds are just bolted right in -- no cutting or welding required. An option to removing the stock cats is to use the Supersprint header/cat combination. The new manifolds/cats are typically used in race cars or high performance street cars where high flow is required but the car must still pass an emissions test. We have used these on our E90 325i and it has passed the Massachusetts 'rolling road' emissions test (http://www.vehicletest.state.ma.us/g...tml#kindoftest).

The Stage 3 software is a re-flash of the software in the car's engine computer. We alter the computer's fuel and spark mapping, adjust the throttle response, adjust the cam and Valvetronic timing, and remove the top speed limiter. Special programming of these settings takes advantage of the high-flow cats and the intake manifold.



We recorded a Maximum gain of 50hp @4700 RPM and 38ft-lbs of torque gain @4000 RPM on our Dynapack dyno. The seat of your pants gain is amazing -- its like driving a different car after this software change. There are NO downsides of doing this except 91 or higher octane gasoline is required.

Maximum gain: the largest difference in the curve before and after the software change. This is different than "peak gain" -- the gain from where the highest HP and Torque figure were before the software was installed. The gains made by this software are simply a night and day change!


Peak HP: 262hp @6300rpm Max HP gain = 50 hp @4700rpm
Peak Trq: 223lb/ft @4500rpm Max Trq gain = 38 ft-lbs @4000rpm
Dyno chart to come!

The software re-flash is done in-house at TMS. Your computer will need to be removed and shipped to TMS. Overnight return shipping of the computer back to you is free.

Well but now we're looking at changing high flow cats and such...
For me, I just want to add some HP (I can add the other things in later) by installing the shark tune.
The old E46 platforms would work w/o all that extra stuff.

Also I wonder if anyone's gotten the Turner upgrade with its high cost and if they did, did the ECU re-adapt?

The intake manifold alone and a tune would get you to 330i performance. The high flow exhaust manifolds get you a bit of a bump in power across the entire rev band.

There is a magazine that did a full test on a Turner tuned 325i. They said it was nicer than a stock 330i. Search on the forum and you should find it.

The E46s weren't really that tunable... to my knowledge, there wasn't one software tune for it that added any peak horsepower. These modern cars are already optimized, except for ones like US 328 and US 325i which are artificially detuned.

it looks like with the reflash only, you still are getting about 20hp out of it.

shit ill take 15 whp
