[CL9] In search of horsepower

[Fredoops]

1. Performance header
2. High flow Cat
3. CAI
4. Lightened pulley
5. Ecu to make car run leaner

Lol what does 3hp feel like. It feels like u cant go any where.

You dont measure how fast a car can go by hp you look at the torque curve.

A cai shifts the curves up to higher rpm therefore decreasing acelleration from the bottom end but gaining it at the top end. Most mods mentioned do this.

Even if you have a flywheel that is lightened it does nothing to the torque curve but it gets you to the higher revs quicker therefore better acelleration.

If you had 1000000hp and no torque(impossible but an example) you would go nowhere as the torque is needed.

Torque equals pulling power without it you may aswell just ride a bicycle.

therefore get a diesel :P

Not all CAI loses bottom end, take ct-e icebox cr example.

Header +cat will shift te entire ta/hp line up anyway.

And about lightened flywheel and pulley, those things reduce driveline loss, because less torque/power is needed to.move them. Same concept as lightened alloywheels

Proof of above statement ?




It's all abit far fetched guys. Even with tuning - short of turbo or supercharging , you are kidding yourself that cai/header/exhaust will do anything on a euro. I've witnessed before/after numbers - 10hp peak gain does nothing to real world performance at the track or 1/4 mile.
Light weight flywheel or other parts is a waste on such a heavy car.

Anyway , if you want more noise and alittle more oomph , please do the usual mods. Just don't expect it ( and please
Don't SAY) that your car is actually any better.

One of our member's (NPcan) euro was pulling 147 atw with IHE and tuning. Then there's all the members from TSX forums that would disagree with you.

Considering stock CL9 makes 110 kw atw, Npcan's euro makes 33.6% increase over stock... Not bad for just bolt ons and piggyback don't you agree?

CL9 at 1300 odd kg's is actually pretty light given its size and features, it's within 100kg of a dc5r, with more torque from the k24 to boot.

Re: lightened Pulley + flywheel. That's just.simple.physics. Rotating mass is the key.

Also, "real world" performance is a relative term. Hell, just by adjusting the CL9's Drive by wire setting will make a night/day difference to daily driving and perceived performance.

Basically what i got fron this is if u do it in a euro your a nut but any other car will add hp bolt on mods on any car will make it better as it removes all the restrictions in the design from a manufacturer

euro stock wieght is more like 1400kg....

friend weighed his euro 06 sport with coils, rims, and full tank... 1410kg....

no driver....

my dc5r with coils. IHE, rims, etc. stripped boot but still rear seats and interior and a 1/2 tank of fuel weighed 1140kg..

the extra torque gained by 400cc does not offset that weight diff of 270kg......

u can shed some kgs by changing front seats, etc..... but my car cl9 still weighs 1320kg with full tank and no driver...........

it's a big handicap to catch up to a dc5r with minor mods.....

[stndrd]

all this talk about changing torque & power curves by changing headers is irrelevant if you do not specify whether you are using a 4-2-1 design or a 4-1 design. On a stock/mild tune motor, a 4-2-1 will actually see a real world difference, as the extra torque gained thru the mid range will make an improvement, as opposed to running a 4-1 design that only gives you number bragging rights by loosing mid range torque and adding only a few hp in the top end.

only on a motor that has had head work ie: cams, cam gears, port/polish, intake manifold, possibly valves will a 4-1 be more beneficial than a 4-2-1 design as the head work will shift the power/torque curves to where the most power/torque is desired by the person paying the money for the build

Official ADR recorded weight is 1390kg for the CL9, so you are right.
Perhaps I should've tried to make the point with a different car, all I tried to say is that CL9 wasn't as heavy as some people tend to think. Hell a MK 5 GTI weighs 1350kg.

I dont disagree the weight is a factor. But as our car has heavier replacable items ie front seats and bonnet it could quite easily come down alot more then another car im not saying its going to be lighter then one however could be comparable for sure

[wuism]

Tbh... Whatever u can remove in a euro, u could do on a GTI. Sure euro front seats are heavy, but so are most new cars nowadays with airbags in the seats. The euro was not made with racing in mind unless u have a euro r which is lighter than the cl9 to begin with. Honda didn't use heavier steel compared with other manufactures.....

Bottom line, if u want ur euro to compete with dc5r etc, be prepared to lose some luxuries (comfy seats, vsa, cruise control etc) and part way with some dollars....
