We decided to test this intake on the dyno today. Temps were in the 90s (unfortunately), but the intake gained approximately 8WHP/7WTQ (at the wheels). With an 18% drivetrain loss, that's roughly 10HP/9TQ at the motor in 90 degree weather. The dyno represents the highest run for each intake (5 runs/intake). With enough adaptation, I think the DME could squeeze another 3-5HP/TQ out of the engine (especially in cooler weather). Besides the nice performance boost, the sounds is pretty intoxicating as well (if you had a GruppeM on your E46, then you know what I mean).



We'll be developing an ECU upgrade for this intake shortly to see how much more can be gained.



And full Supersprint system goes in Monday...I'll post up some runs for that as well.

Wow that GruppeM looks so flush. lol Looks like just like my E46 i'll be getting a GruppeM from you in the future for my next car haha.

Thanks for the dyno, looking forward to what you guys have planned in the future. Do you know the offsets of the rear BBS wheels?

was that car auto or 6mt?

Thanks for the dyno. I'm curious to know what this looks like under the CF cover. Is there any shielding from the hot engine compartment? As you know, the engine compartment is practically sealed completely, save for perhaps tiny gaps in the plastic and the ducting routed from the kidney grilles over the radiator.

With those numbers, I'm 99.9% certain it was the 6MT.

Before doing any of these performance mods, I'm going to re-dyno with the new wheels for a baseline.

Damn what a gain!

Too bad its around $1,000......

One day I will have one of these

I guess my main concern is that when dyno testing, the hood is up, so all the hot air from within the engine compartment gets vented (heat rises). When driving, the hood compartment is enclosed, so much of the hot air would get sucked back into the engine. I'm not sure how one could or would replicate those circumstances, but this is why I'm curious to know if this intake is shielded from the sides in any way.

I'm also very excited about the Supersprint exhaust with HEADERS! For all you sound buffs out there, wait till you hear this one. I have a feeling it's gonna be a little on the loud side.

Cant wait to see that exhaust system!

[XxLancaxX]

Nice posts. Can't wait to hear the full exhaust installed and running on the dyno.

It's 100% sealed as far as I know so as long as hood was up on before and after dynos, its fair to say there will be a gain when driving.

They are 20X10.5 ET30, rear fenders were widened 1.5" to accomodate the larger wheel and tire.

The filter is completely sealed off from the engine thanks to the heatshield. I don't have a full pic of the shape of the shield, but here's one to give you an idea.

That's a valid concern, however, there is a tradeoff since the car is stationary and not moving. So even with the hood up, the heat buildup inside the engine is about the same as if the hood were closed while driving. We used two 3500CFM blowers for these runs, but they still don't compare to the amount of air being pushed through the radiator and engine compartment when doing 100MPH+ (ie. WOT in 4th gear). In the end, having the hood up doesn't really skew the results that much.

Another for reference...

For your ECU upgrade, is it tuned specifically to be paired with Gruppe M intake?? I know you can just get the ECU reflush alone, but I would like to know if the way you reprogram the ECU will only have its max advantage with Gruppe M intake installed or not. And lastly, what's your ETA for ECU upgrade??

We'll have 2 ECU upgrades, one for the intake, which will be part of our Stage 1 power kit and a regular ECU upgrade for those without a CAI system.

And lastly, what's your ETA for ECU upgrade??

We're going to start on decoding the map locations in MSV70 in August, after we finish a couple E46 SC/Turbo projects we're working on right now. Depending on how much work is involved to decompile and reverse engineer the code, it could be 1-3 months before a beta program is developed.

Does your car have to be there for the retune or can I just ship you the ECU?

Gruppe M CAI or any CAI ??

You can ship it to us, 2-day turnaround.

It'll be tuned for the GruppeM, but will most likely work perfectly well with any other CAI, provided it's a well-designed piece.
