I ran some numbers and can't use straight up percentages... comes out to a 1000ft difference which = basically .1 in the quarter which = .8% which = 382 as I posted earlier which was a basic guess on my part... so looks like I'll stay E20...


Lot of whiches but hey it's Halloween.... lol...

Lol... i never run any type of corrections or adjustments. I understand their purpose, but my mentality is the car makes what is makes and is as fast as it actually is. So if your car is slower or makes less power because of atmospheric conditions, adjusting your results based on that compared to more favorable conditions is just dreaming. Doesn't mean your car is any faster or more powerful. I think its annoying when people post dyno numbers or other results with correction factors - their car didnt actually make that much power. It's like saying 'yeah my car can make xxx hp or run xx.xxx in the 1/4 mile'... but did it actually? No.

I see your point totally but for a better comparison for myself I like to do it... It's so close it's almost not even worth the time of doing it... so future logs i'll just post straight up for logs on my car... now where is that BM3 2+E30 log I'm dying to see before black-friday...someone has gotta have a 4th gear pull totally stock turbo..

Sounds like you may end up being the guy you’re looking for.

I wouldn’t stress if you don’t see the logs you seek beforehand. Stg 2 E20 MHD and Stg 2 E30 BM3 are fairly similar in power since the stock HPFP is the bottleneck.

But, Stg 2+ E30 BM3 blows them both away, and I’d guess you’d pick up ~25whp if you have all the supporting mods to go with your stock turbo.

Finally found out how to include AFR and manifold boost in VD Here my latest performance check with "nice and cold" 28°C ambient

Can is running awesome! 100-200kmh in 7.5sec

Wow... Just to verify this was the BM3 2+E30 ... Your in the top ten on the fastestlaps... ... right between a 911 GT3 RS and a GT-R!!!!

I think he’s custom tune with a PS2? Could be wrong, tho.

440whp is what a PureBoost tuned PS2 M2 on 93 put down on the Dynojet here on a 90F day. That’s the car I’m mentioning when I’m saying my car did 15whp less with a beta of the BM3 Stg 2+ E30 and E47 with my smaller Dinan turbo and spark plug gap issues.

I’m guessing I’ll be 430+ whp with the OTS, fixed plugs, and a cold day. Will find out soon.

I searched high and low last night for logs and really couldn't find any good BM3, F30,EWG, Auto, stk turbo clean 4th gear pull.... I found one that was close but from what I gathered BM3 and MHD are basically the same for OTS E20/30 maps ... basically around 400whp... now the new custom BM3 E30 map of 30whp I'd like to see a clean run on the car I listed before to compare apples to apples... but 30whp @ $3,000 for me to go HPFP is cringing... tough pill to swallow... but I might do it... lol... Wedge has been doing some crazy things for MHD... I'll give them a call...

Well, you need the supporting mods either way, and you can get an HPFP for ~$1500. Then, BM3 for $600, or wait for MHD to come out with a similar map.

So, you can do it for $2k’ish, but if you decide to spend another $2-$2.5k for a larger turbo, that’s where the big power comes in.

Think of it as a required stepping stone for now.

I want the micron filter and sensor... labor to put it in.. doesn't matter MHD custom or BM3... still $600... so for me it's $3,000

Well, might as well add another $3k for turbo and install, and go from adding 30whp to 100whp.

Or I can buy a N52 cam for $240 used and couple hundred for labor... custom tune increase timing and get substantial increase it looks like all for $1,000 ... ... I'm just going to get my coilovers put on for now along with the strut bar and see what the holidays bring... ... seeing his bearings made me cringe though....

Mods in my signature. Yes, GPS verified 7.5sec adjusted for flat road so pulling really nicely indeed M135i is a 1500kg.

You gonna do it?
I'm curious to see what numbers on a stock turbo the cam swap would do
I may be a pioneer and do it but it'll be a bit, haven't opened this engine up yet so I would need to plan a solid weekend to do it and get tools together for it.
Got me thinking tho

I thought this whole cam swap thing was mostly debunked and the gains were attributed to a more dialed custom tune?

That's possible I don't know much about it and to be fair I have seen some pure stage two cars make similar power on stock cams
But I'm not sure I've seen that much whp with that much wtq together on one car, but I also haven't dug around as I'm not at that stage with this car yet, very curious tho

Actually there is only verification of math that the lift is minimal... equal to a very mild lift aftermarket street cam... 100 gain is super hard to accept... 30hp and I say ya... I can totally see a custom cam swap helping since these motors do die out top end... nobody has posted results since.... soooo.... now would this warrant a HPFP upgrade... just to be safe I'd say yea...

P.s. read that gotta becareful about valve overlap ... mentioned MAYBE not good for highboost PS2 applications..

In the end for me... too much headache at this point...

No doubt it isn't even about the final numbers but more so the curve that has my attention
It held it really nice in the top end, this video was a bit hard tho because I feel like his tune was a literally a base tune then does a cam swap and custom tunes it, he only made 12whp or so and lost 5wtq over just a cam on same tune
Custom to custom would be more fair but I can see the curve and can't deny it looks good

this is way more feasible... MILV supports

can't post the article... only increase peak 5hp but carried 35hp more upper rpm stk turbo 93 tune only dp s55 ...

So I finally had some time to dig into this log and i did a comparison to one of my most recent log, see the attached table screenshot below. My log its from MHD Stage 2+ E20 OTS Map. I have FBO + more (inlet, intake in this log, etc), but stock turbo and HPFP most notably.

Note, your dyno run was in 5th gear and my log was in 4th, so i pulled values from corresponding RPMs rather than speeds. Here's my log: https://datazap.me/u/thejeremyman9/3...27-28-29-30-31

I think the interesting thing is that the MHD map runs a bit more timing at peak TQ RPM, but less timing up top (probably because its an E20 map and its not as aggressive as a custom tune would be). Also interesting is that my boost is basically the same (slightly higher) at peak HP RPM, likely due to stock HPFP limitations. Aside from that, the values are quite similar.

My guess I would be making about the same torque (trade 1 psi for 2 deg of timing) +/- a few, but you would be making a bit more peak HP (2.3 deg more timing), which makes sense. This of course is only peak #'s and says nothing about area under the curve but interesting nonetheless since your log has corresponding dyno results.

FastF30 probably likes this comparison since he's all about these estimations recently lol.

It's basically the same thing as bigger ratio roller-rocker arms... I always wonder if there was something can be done OHV... so I emailed them to see about a upgraded HPFP is required and what typical gains to be made on the N55.. Yes.. I'm very interested in this.. $1500 +/- including labor and tune...25whp up top???? yea it's worth it... I was told many years ago when you start hitting 11 second quarter mile times... the cost of Hp is roughly $1,000 per 10whp (that's everything included)... seems it still holds today... so this would be a good deal...
