Doesn't look like it can be retrofitted.

I think a few E9x M3 owners got a little upset with the fact that they were getting smoked by guys with just a "$500 tune"

Torque doesn't always drop off at 5252 RPM, that is just the point where the hp and torque lines cross in a dyno plot with specific scaling. A car can make more torque at 6k than 5252 if designed to do so, look at an S2k for example.

You guys should read the original post over on n54tech. The 427whp is on 19psi so the n54 on map 7 fbo with e85 is making roughly 450whp at 18.5psi. Both the M4 and 335i are tapering boost up top as the dyno and log show. The 480whp is on a thrown together stage 1 tune that is in the 21psi range also tapering down. You'll also read where I tried to say there would be some decent gains with downpipes etc.. Terry was pretty quick to crush my thoughts on how much more power was available. Basically my impression is the M4 is running closer to max boost already and might not have the same head room as with the n54. There's still hope as we all know Terry can work some pretty wicked magic!!!

Just curious.
Looks like all mods from now on will be piggyback.

There is a retrofit HPFP on the market.
A vendor on this forum.
I don't want to start a debate.
Search.

I know all about the retrofit from the vendor. The question was if the new M3 HPFP would work with the older E90. Who said anything about a debate?

Shoot I'll be happy with the Vargas upgrade if it comes out!

Have you seen the afr on the m3 with tune??? It's so damn lean... That's probably the only way terry was able to hit 480. I don't know anyone n54 or n55 that runs as lean as he ran his m3. 15:1 I believe it was upto 5k

[dx1541]

I reckon even in factory trim it runs rather lean in that area to get better gas mileage during part throttle daily driving in that rpm range below 5k, as it runs to the top the A/F dives down to 11.0 which is as safe as any manufacturers want it to be. With that kind of A/F, timing is also low as witnessed on Terry's log posted on the other site.

Nothing too dramatic IMO... the damn motor runs a water to air intercooler now, a big step up from our regular air cooled units. Constant IAT's at all speeds....keeps the motor happy...

I think you misunderstand how a water to air intercooler works. It still requires an additional exchanger that dumps the heat back to atmosphere. It is more robust but it still won't be constant IAT's and once you heat soak it will be much longer to cool off the loop. It's not the same as running a chill box in a race setup.

Yeah I did... based on what's briefly available there isn't much you can squeeze out of that setup... Like Terry, I'm surprised at the lack of power being produced at 19psi. That isn't a very promising number thus far.

Right. And that's actually the same story for the M5/M6 motor. It's not necessarily maxed out, but there isn't a mountain of power to be found on just a tune.

Update from Terry. This car is proving to be quite the potent platform.

Hey guys,

Was able to swing by a private track for a handful of VBOX passes. I did two passes stock and one pass with alpha tuning in place -- just to see where we are at. All runs were done on E20 fuel, temps in the mid 60s. Boost on the OEM runs hit around 17psi, and around 23psi on the tuned runs. Note I didn't launch hard for any of the runs as the car only has 250 miles so the ETs are garbage. Traps are telling though. The files are posted via the vboxtools.com site which averages the last 60' of the run like a real track would.

Net result was ~118mph stock and ~124mph tuned. The funny thing is the tuned run would have been faster had it not been for DTC kicking in after each shift. With some more massaging I think 127mph 100% stock with E85 will be possible.

[Glowin]

The car runs 19 PSI stock from the factory???

AND he's on Jalopnik now!

"Well there ya have it. BMS has already tuned the M3 to the realm of 479rwhp/484ft-lbs. Not bad considering the official US release is Saturday. Color me impressed."

PS LOL, so is Shiv now going to all of a sudden pop back up in the scene after abandoning piggy's here?
