Ok as some of you may know I had the mugen induction kit on my car and wasn't very happy with the cold air flow issue as the last time I had it Dyno'd it was reading 40oC and it should be around the 20 mark or lower.
This is due to the hot air coming from the rad and being pushed back into the mugen air scoop..
Anyway I decided to sell the Mugen and buy an Injen CAI.. below you can see the dyno results..
Now the first result is the Mugen induction kit on my car with Hayward and scott exhaust and hondata ECU. On this run I got 187.8whp which is about 221 bhp BUT air flow was reading 40oC... not good..
ok now here is a run with my Injen induction kit on my car with Hayward and scott exhaust and hondata ECU.. On this run I got 179.8whp which is about 215 bhp ...
Mugen in BLUE
Injen in RED
So as you can see the Mugen has given me better top end and better low down but the Injen is better in the mid range giving me 5bhp over the Mugen ..BUT the good thing is the Injen is only 14oC in it temps which is much much better..
So to sum up on these two induction kits...
The mugen is a better induction kit giving you about 4 - 8 bhp gains BUT I reckon you need to have either the Mugen front bumper or a good air flow bypassing the rad to get the temps down to get the most out of the Mugen..
Downside: Price and air flow.
Upside: Incased in engine bay, looks nice and easy to fit
The Injen I think is better in the mid range (and I can feel the difference there) and I am very happy with the temps.. plus it sounds the bollocks too :wink:
Downside: Could get wet, changing the filter means taking the bumper off and around 3-4 hrs to fit
Upside: Price, cold air flow is better and sounds wicked
****************
Ok so at the moment I have lost a little bit of the top end.. remembering I do track days so top end isn't that important to me right now..
Now lets add the Jackson Header (manifold) on to the car... (unfortunately I didn't have the mugen at this point so I am rolling the car with just the Injen).
For our final run I have the Injen induction kit on my car with Hayward and scott exhaust, Jackson racing header and hondata ECU
As you will see below I am back up to 188.4whp, which is about 222.bhp. Meaning that the header has given me 11bhp..
Also if you look at the dyno it has given me about 5bhp in the mid but my top is about 6-8bhp.. plus as you can see the power didn't die until we hit the limiter (which I told him to keep going until we hit it)
Injen on its own in BLUE
Injen with Jackson Header in RED
So with the Jackson Header and the Injen I now have about 8bhp in the mid over the Mugen, but as I couldn't dyno the car with the header and the Mugen I have no idea what gains could of been had there...
If you take the fact that I dyno'd at 187.8whp with the mugen on its own, then I might have got around 198.8whp with the mugen and the Jackson Header giving around 230bhp which isn't bad at all for these cars...
But that is just a real guessimate..
Overal I am very happy with this setup as I now have the power in the mid, which is where I wanted it for track use plus my temps are nice and low.. and the car sounds wicked..
But I will still need to buy the K20 Pro as I am running very lead :? and I reckon with the K20 Pro I will get a more bhp out of the car, maybe around the 2-4bhp gain plus lots more ftlb... :wink:
K20 Pro is on order so watch this space for the next dyno...
