Reaching 140kw at the wheels

[Nuci]

Hey all,

Ive set myself a goal of 140kw at the wheels on a 'safe' tune in my DC5R, and ive got a plan of everything that I want to get:

Mugen Intake
Toda Headers and Hi Flow Cat
J's Racing 60RS Catback
Haltech Platinum / Hondata K-pro ECU

Obviously there are a number of other supporting mods that will go with these. But the final piece of the power parts puzzle is cams. There are heaps of brands and variants of cams on the market (Spoon, Toda, Skunk2, etc), and i wanted to know peoples experiences with what they had used. Keeping in mind my target, and that the car will be street-driven, what brand / stage do people recommend?

Is this goal realistic? And is it possible i could crack 150kw atw with these mods?

Any help would be great. Cheers, Daniel.

You would be better off with a 3" exhaust and make sure the headers have a 3" collector. 140-150 should be easy.

[Uproar]

curiously, how much would all that cost?

[M@lew]

That should be able to get you close to 140. Uc is running Amuse + Injen + Xforce headers + Kpro and he made 137kw atw from memory. With cams, rbc etc. you'll definitely hit 140+.

Hey man,

Toda headers + toda cat, injen cold air intake, skunk2 megapower 70mm catback managed to pull 126 kw atw on the toda dyno (not tuned). This dyno appears to give a very accurate reading as i've dynoed my car on other dyno's made 132 atw.

With enlarged throttle body + upgraded intake manifold + ecu + right choice of tuner you will definitely see 140 atw.

If youre buying new:

Mugen intake - 1200
Toda headers and cat - 1750
Cams, valve springs, retainers etc - 2000
J's Racing catback - 1200
K-pro + tune - 2500 ???

K-series parts arent cheap unfortunately...

Holy crap so $_$

Which those mods you'll easily get near to or at 140kw.

My car right now has 137.7kw with spoon headers, spoon n1 cat-back, gruppeM intake, and haltech platinum

[SpoonS]

anything after that will get you to 150 or more i think

^^ Very nice power. I was looking at Skunk2 cams myself. I also noticed you went a 3" exhaust, whereas mine is only 2.5". I didnt think a high-revving 2L NA would need a 3" exhaust??? While 140+kw is the goal, i want to build a car that is super responsive as well, not all top end power.

[chubby steve]

still got great down low power just its traction happy even with 18s

[OMG.JAI xD]

...Just run the car with a DynaPak dyno. You get higher readings with it.
dc5R with TODA equipped exhaust and injen intake with a piggyback will make 145kw atw using that type of dyno. Though its only for bragging rights.

Making power isnt hard. Its making use of the power thats hard. You can have 140kw with no torque. Ie a hayabusa engine. All about balance, and sometimes, branded parts arent all that.

[DC4Integra98]

a dyno is merely a tuning tool.. a tuner can make a 150rwkw car show 400rwkw if he wants.. most don't go to that extreme, but some do show high figures to justify their equally high charges..

Be more concerned in the curve. In saying that, a dynapack chassis/hub dyno would read more consistently and accurate than a roller dyno. Simply because it won't slip, and so would be more accurate for tuning.

[Nuci]

So does anyone know of any tuners in Brisbane with a dynapack dyno?? And any recommendations for which camshafts i should get?

For a street driven DC5R, <140 FWKW is more then enough power. I'm running 17x9.5 (245/40's) on the front and still "suffer" from torque steer. I don't think it's noticeable, but some people that are use to RWD cars freak out when they drive the car.

At the end of the day, it's all down to the tune. I had Adrian from Toda tune my car, and I told him from the get go "I'm not really fussed about the top end, I want torque", and torque is what he tuned for. Now my car is more then happy to put around at 60km/h in 6th at 2k rpm and it doesn't labor at all. Also has fantastic response from down low.

I have since fitted Toda headers with a 100cell cat, and there was even more of a power increase... I'll get it re-tuned when Adrian comes back up to Brisbane, but I would be easily getting over 140kw on the Predator Motor sports dyno at Browns Plains (Which is where Adrian tuned the car last time)

hmmm interesting.....only an Intake, Header, Exhaust mods and something new, a "Haltech Platinum" ECU on a 137.7kw Type-S....If i want to sell my DC2R someday, i will consider a Type-S.
