An Open Challenge to the Aftermarket

Red__Zed

it would be nice.

The wheel weights is my biggest complaint, and that one just makes no sense.

Trips

Same here.

Jordo!

Really. I have yet to see clear evidence of it outperfoming it -- links? Dynos?

Where is the back to back comparison? SO far all I know is that piping airfrom in front of the radiators (LTI/CAI) makes more power than drawing in in from behind (SRI). However, the OEM airbox also draws air from in front.


Shops have lifts and techs -- invite someone over with their current CBE, swap it out, and face off against the competition.

Now to be fair, that is more work ...

But facing off against a set of K&N panels is NOT a big deal or expense.

There's a new intake under development even as we speak -- I hope they keep this open challenge in mind.


^^^ Hear that, wheel salesmen???

If you don't know, break out the scale! For 2 - 4K for a set, I think this isn't too much for consumers to ask

Yes, but the the internal structure of the factory air box is more convoluted than simply having a filter leading into straight pipe. That is where the limitations of the stock intakes are found even with new filters come from and that is why I believe that they can't produce the same power gains as a set of long tube intakes.

Jordo!

Thus, I am calling them out. I am hoping other potential buyers will do the same.

I agree 100% with the theory -- but I have yet to see clear evidence of it. Actually, I was surprised to see the panel filters plus smooth tubes making approximately equal gains.

Also, you keep making reference to the longer tubes as if the tubing length itself (rather than where it pulls air) is important -- it might be, but longer tubes tend to move peak torque down not up. Does that appear to occur with the longer tube intakes? Do they mainly gain in the midrange?

Again, I am looking for clear empirical evidence of performance differences -- how hard would it be to test?

where are these links of K&N making equal gains ? I have seen numerous G3 dynos.. I have yet to see a single dyno of K&N making 7-8 whp on any car site that I have ever looked at. 350zs did tend to make similar power with stock intakes compared to JWT short ram and same with 370z short ram intakes. But the LT intakes (more a year or so ago ) had dynos popping up with power being made repeatedly... most of it is way up top but power is made... G3 , AEM, and Injen

Here is a link to a dyno, that was the very first thread that popped up when I google searched... made 20 WHP , yes 20 WHP

and here is one from Semtex, another repuatable forum member who had HFC and Berk CBE + 14.8 WHP

ummm, i think that argument should be over
