Nope... the problem is that the same mods can respond differently on similar cars!!

What typeR said above, which was the opposite of my examples... could happen!!

I've seen dynos where the headers got 28hp at the wheel, but the intake only about 2 or 3..... but I've also seen dynos where people got MORE then advertised!! The general rule is that you cannot add mod gains together, but there are always exceptions to the rule......

 

I found the intake, exhaust, headers but where is the chips? I looked at the Jet website. Where can I get an aftermarket chip?Thanks.

 

Ok as for the EVO exhaust system "does" it give us CLSers 10 hp, or what? I can remember last year that the norm for an aftermarket exhaust was about 4 horses, but I guess things have changed. Also if it does give the engine an aditional 10 hp is that to the crank or to the wheels?

And about the Jet chip what are the results? how much of a hp gain? And is it to the wheels or to the crank? Also at how much of a sacrifice, gas milage?

Tnx

jet chip has no "proven " gain and exhausts well comp is supposedly 3-4 but someone bought the mugen and got 13 top to bottom if i remember...

 

I went to their facility and checked out their dyno setup. They have a huge fan blowing air into the car and a huge fan on the back end. They're pushing more air around than the average dyno shop.

 

astro dyno'd at 205 stock...

 

Somebody here dynoed it at 6hp to the wheels. I think it was blxmjx.

The only person who I know of who got the Mugen exhaust and the first on this forum is Spiro. But if I can remember he didn't get a large gain in hp.

Eh Migalea,

Is the 6 to the wheels from the Jet chip or the EVO exhaust?

Ok, people are obviously confused about peak horsepower
gains and max horsepower gains.

Peak Horsepower gains is what this thread is talking about.
On a stock TLS, our peak hp at the crank should be 260 @
6100 RPMs. Now you have to put RPMs into the equation.
Peak HP is always the highest HP in the power band.

Max Horsepower gains is what companies advertise.
It's simply the largest gain in HP regardless of where in the
power band it is. It is NOT necessarily the same as Peak HP.

A mod may advertise it gains 20 hp. But if that 20 HP is all
at 3000 RPMs and adds 0 hp at 6100 rpms... then your
peak HP is still 260.

That is why mods are not cumulative, because the advertised
hp gains are not all at the same RPM. People not only need to
ask if the gain is at the wheels or crank... but also what RPM.

And people need to work on their math. Math ownz you.
240 whp with a 23% loss is 311.68 at the crank not 307.69.

whp / (100 - percent loss as whole number) * 100.

 

When I dynoed the Mugen, I received 3HP/3TQ throughout the whole power band. The 6hp was from the EVO exhaust.

 

Ok, so what do you think the "S" is putting out for hp at the crank and wheels with the mods stated in the thread?

 

Cool Tnx

So would u agree that the EVO is the best performing exhaust out there for our cars?

I own your Mathz Kid... Check your numbers...
You get the formula messed up !

Let us see

Crank HP = Wheel HP / [ ( 100 - % loss as whole number ) ] / 100]

So with:
WHP = 240
% loss = 23%

Crank HP = 240 / [(100 - 23) / 100] = 240 / 0.78 = 307.69

Double check, 78 % of 307.69 BHP gets to the wheels = 240 WHP

Get it....!!

 

If someone verifies that it was the EVO that was dynoed. Yes.

 

Just one probem (unless I missed the round off section):

100 - 23 = 77 (not 78)...

so, 240/0.77 = 311.69

and

311.69 * 0.77 = 240.0013

Details....

 

I am basing my 78% to the wheels base on the average of stock dyno showing: 200-205 WHP.. so the loss is 23% down to 21.15% I picked the average of 22%.

If you go by 23% loss.. you get your 311.69HP if you pick 22% then you get 307.69 HP

Still 22% is a lot of loss! almost 67.69 HP are gone!
