Dinan stock and mppsk numbers

Anyone notice how Dinans numbers for the stock 340 and 340 with mppsk are basically the same?

Just wondering what everyone thinks about this.

Presumably the Dinan is cheaper than the MPPSK I take it? Does it have a warranty? Personally I would go with the MPPSK even if it costs more. For peace of mind and increased residual value.

Not really what I was asking. They dyno both the stock 340 and the 340 mppsk and both cars have pretty much the same numbers. It's as if their dyno shows no difference between the stock 340 and one with mppsk

Yes. They also have odd ways of measuring hp and trq. They explain it somewhere but in this case it is either an inaccuracy or maybe some of their test cars had problems - or a marketing tactic . There is a forum member who did a pre and post mppsk proper dyno and numbers checked out as per BMW.

Dinan gives what they are calling "Crank" numbers, I don't know if they are or not but anyway that is their starting point. CptCrunch's Dyno was Wheel HP and if we assume 12% driveline loss then Dinan's stock number of 381 non MPPSK would drop to about 335 HP which is close to what we see. Add Cptcrunch's 37 hp bump from MPPSK and WHP goes to 372, add the 14 HP the Dinan Elite for MPPSK get's you over the stock Dinan Elite and we are at 386 WHP add another 2% for any possible under estimate's and we are at almost 394 WHP, where is the fuel cap? About 395 WHP as far as I can guess. The problem with this equation is when you start to factor JB4 and it's results plus Dinan Sport and JB+ not to mention Active Autowerks into the situation my numbers start to become more and more suspect as some of them seem to achive higher gains.

edit: Dinan wants to take all the credit for getting the Dinan MPPSK to it's max of 395 WHP when it's only adding the last 14 HP or so ... dam I hope this is making sense.

I'd say its a pretty decent bump + exhaust for the $$

I took a 440i that had MPPSK for a test drive and then drove my 340 (that doesn't have the kit) home and really didn't notice a difference power wise. The sport exhaust was definitely louder.

hmm....I drove a 340i with and one without back to back and could definitely tell. That's what made me order mines with.

I've only driven my 340i with so I can't chime in with the but dyno.

But these number make think that dinan wants people to believe there is no difference when they add the mppsk so they will just order dinans product instead of the Bmw mppsk

Part of the issue is the vast majority of folks are seeing those 2 charts and assuming they are the same car. They are not. The numbers for the MPPSK and non-MPPSK cars are completely different vehicles (440i w/ MPPSK and a 340i to be precise). Not all cars are going to be identical in performance so there is some of that at play.

More importantly though is when you look at simply the peak numbers they are very similar between the MPPSK and non-MPPSK cars. However when you look at the entire curve you can see that the MPPSK car is running a decent amount stronger then the non-MPPSK car, particularly in the low end. Its only at the upper end of the RPM band that the 2 sets of numbers become more and more similar. This basically is the same thing we have seen over 3 generations of MPPK/MPPSK cars in that there is a decent TRQ gain but minimal HP gain with the package. Essentially low end power is what you are getting with MPPSK (TRQ). This explains why people feel something as you are feeling the increased TRQ down low even if the HP up top isnt really there. Its been pretty consistent though every time we have measured one of these cars.

Perhaps how the Dynapack measure's equates differently in the grand scheme of things versus how a Dynojet does w/ MPPSK but ultimately these are the numbers we saw in house. We aren't trying to claim something we are not making (hence why we list the factory rated numbers as well as what we measured as stock). It is what it is and if you choose not to believe them that is your prerogative.

Drove 440, 340 mppsk and M3 back to back to back..

440 felt more than my 335, 340 mppsk improvement was a greater improvement than from a 335 to a 340. Seem fairly significant.... The M3 did NOT feel that much more than the 340 with MPPSK...

Telling you... B58 motor plus MPPSK seems significantly more than my 335 - yes but dyno works when you drive them all back to back...

I would have gone M3 if it had AWD and had all season tires and/or was significantly more power... but the MPPSK honestly was so close, exhaust actually sounded better, ride was far better, it was hard to justify the M3 outside the brand and track capabilities (which I wouldnt use)

Anyway... MPPSK B58 is significant coming from N55 stock. MPPSK vs Stock B58 you will see a difference enough both in performance and exhaust tone to agree with the purchase.


Dinan is completely lying...

Thanx for the explanation.

And I'm still very interested in the stage 1 tune. Just slightly disappointed with the numbers shown with the mppsk from Bmw. Hopefully someone can dyno all three scenarios as they add mppsk and dinan stage 1 so we can see the increases with each stage.

We know from cptcrunch's dyno MPPSK took his B58 from 331 WHP to 368 WHP, we know Soultraveler00 dyno'd 383 WHP with MPPSK but had no before dyno. All the dyno's I've seen put stock WHP in the 330 range and the MPPSK dyno's indicate around 375 WHP give or take a few HP. A couple of MPPSK to MPPSK + Dinan dynos would be really nice but Member CCnYiting has MPPSK and Dinan on order and has stated Dyno's are coming, we should get a pretty good idea where things stand after that happens. One thing to keep in mind, as Dinan has stated looking at a few points on the HP and TRQ curve will not neccessarily give the most accurate representation of the worth of this product, one of the beta testers has stated he/she is quite happy with the tune and I'll give that statement some consideration while looking at the numbers.
