Gruppe-M purchase! & review w/ pics

[EL_DC5]

Cool, as i do know that my Type S rev limiter would move slightly (100rpm iether way) on the tacho depending on load, gear etc. Not sure if the car is revving more or the Tacho is out, but it did this before the intake. I personally haven't noticed anymore RPM being pulled out of the engine since installing the intake. None the less glad to hear your enjoying it, the sound of VTEC up around 8500rpm is just Magic.

Yeah but where suposto be hearing it at 9k

Just thinking about the noise of a Gruppe-M at 9000 rpm makes me all funny

Ok EL Dc5, its the bracket i was talking about. its near the injector lines but the bolt your missin i never touched mine or even looked, im pretty sure i used my own bolt for that bracket to bracket..

Matsski, im pretty sure my rev limit has gone up. i rev past the red line by 300 or so.

and my cars stock as a mofo for engine work or performance

Cool, does anyone know where the stock rev limiter on DC5R / DC5S is? From memory i believe the S makes power / torque slightly higher. I just don't see how the intake would have increased the rev-limiter as its controlled by the ECU. By this i mean does anyone know if the rev limter is set to only kick in at a certain point in the Rev Range, or is it controlled by more variables (load, gear, etc) Any ideas??

my dc5r would redline to 8200 before, i think i got it on video ill need to find out

with your other question! someone needs to answer that

[Mattski_VTIR]

Cheers Type S Redline is 8100rpm and i believe the rev limiter is around 8300 / 8400rpm??

The only thing that controls the rev limiter would be the ECU itself. The rev limiter is a set value programmed by the ECU and is not changeable on the stock ECU based on any other factors. The only way you would be able to change the rev limiter is to use modifying the ECU with a program such as Hondata KPRO. With the Hondata KPRO, you can either increase or decrease the value as you please

forgot to mention massive improvement. it want to keep going to 9k rpm, It goes to 8500 b4 it realizes to cut out so i got an extra 100rpm out of this intake nice

Are u sure the intake allowed you to rev an extra 100rpm? As i dont see how the intake would have change the rev limiter??? Anyone else care to share ?

The stock analogue tacho meter is inaccurate and will tend to give you a misleading figure of about up to (+ or -) 300rpm in the upper high rpm boundary. What you are seeing is the result of inertia occuring when the needle revs past a certain point and 'bounces' back. The only way to accurately determine the rpm is to use a digital meter of some sort directly connected to the ECU or a KPRO datalog, RSM or any other digital rev meter reading.


(Btw I'm looking for a post quality point! *hint hint* )

Hope this helps!

Great thanks, this has just confirmed my original thoughts
Cheers

From what i know of, the DC5r REDLINES at 7900rpm and the REV LIMITER engages at 8400rpm. I believe this as my type r hits the limiter at 8400 on the dial!

DC5R = MAX 8100
DC5S = MAX 8400

thats from honda service i just called them.

Honda has got a bolt for me its a common 8 x 16 bolt. and it was missing from factory on mine for some reason

Interesting, lots of reports ive seen back my claim up of 8400 for the DC5R as well.
