Loving this build. So the exhaust is just straight piped with universal mufflers?

I would recommend throwing at least one set of resonators in there. Wont restrict the flow and just cleans up the raspiness

Ignoring the wine does the harrow have any induction noise that replaces the oem air box?

Ok so i may have got WHP mixed up with HP over the phone so i have adjusted the WHP specs in the previous post. This it what it put down!

Things to know:

BPC purchased the kit without the option of a tune. BPC did 100% of all the tuning for both N/A and Harrop.

We are going to drive the car over the weekend let it adapt and make the final adjustments after the holiday.
The supercharger graph was done on a 90*F day inside shop temp with 42% Humidity
The N/A tune was done on a 96*F day inside the shop with 34% humidity
Raleigh is 315ft above sea level


Graph 1
Bone Stock VS new drop in air filter, BPC tune, American Racing Headers full exhaust

Graph 2
Shows Time difference to accelerate the same gear to same MPH before and after blower.

Graph 3 & 4
BPC tune, drop in filter, ARH full exhaust and Harrop in both STD and SAE

So I've been to a Cars and Coffee and a meet up and its safe to say people LOVE the sound of the Harrop / American Racing Headers + full exhaust. Best part about it is that the car is still fun to drive! The noises this car makes are intoxicating! Every now and then i get on the ground to admire the headers

Interesting. My E92 6MT with Dinan intake, cat delete, and BPM tune made 380whp and their dyno.

ARH headers with a tune = delta of 38whp from stock.

Yeah we actually noticed the new(used) motor was a little low on power whenever we dynoed it the first time. I know that a healthy powerful motor depends on the car and the person that had it before hand. I had a 08 e92 M3 6MT interlagos blue that only put down 325 rwhp stock and then i also had an 2011 E90 M3 6mt ZCP that put down 350 rwhp stock. Either way the headers are netting us about the same amount as you saw. 38 whp.

How do you like the headers?! I absolutely love mine

Blown beater doing blown beater things...

Recently i was invited by my Sponsor Bimmer Performance Center to go to the Ocala, FL for the October 28th-29th 2017 Wanna Go Fast 1/2 Mile race at Jumbolair. We intended to run the M5 and set a record but we had a small set back so we decided just to wait. Instead i beat the hell out of my daily Harrop M3 beater!

I was shocked at how much attention the car got! Doodoo paint and all! I kept getting compliments on the sound of the supercharger and headers. Even the owner of Wanna Go Fast stuck his head in and said "is that the Harrop Supercharger?" Next thing you know he's taking my car for a spin down the runway and makes short work of a Alfa Romeo Giulia!

Updated list of Mods:
Harrop Performance TVSM3 supercharger
ARH Long Tube Headers
ARH Catless exhaust
VAC Rod Bearings
Michelin PS4S 265/30R19 - 295/30R19
Mach Schnell CAI
Bimmer Performance Center custom beta tune

Thanks to:
Dan (owner)
Bob (tuner)
Eric (fabrication)
Tom (sales advisor)

Thank you for the kind words. Pretty uplifting on a day like today...

I was part of a Hit and Run today so I was pretty upset. The guy was parked next to me in a big work truck and either wasn't paying attention or just didn't see my black ass car... Either way he managed to sideswipe my left front fender, fucked up my power steering pump, and avoided showing his plate to the cameras.

Oh well that fender needed a miracle anyways

Time to come back stronger than ever... to be continued...

Oh no!! People can be such jerks, wtf...

At least the car is in your 'more than capable' hands, I know it will be well taken care of. Minor setback. *trying to not be emotional* Although I am very sorry that happened. I wish I could help... *hugs*

[DreamTime]

Oops, I just realized I should probably make sure you know I'm a girl (hence the emotional and hugs thing )... Don't want my comments to be taken out of context...
