I was ~~><~~ close to breaking into the 15's. Arrrghhh! Decided to pack it up after making 7-8 runs. Below is a picture of two of my quickest 1/4 mile times. What's interesting is, one of the times is with the stock intake slightly modified. The other is with a 'track only' test intake pipe I made with some intake parts I had in the back of the Fit.




Similar 1/4 mile times but the prototype intake had a higher trap speed. So there is power to be made by installing an aftermarket intake. Be sure to route the intake in such a way that you are pulling in cool air. Just don't try what I did at home....please. It was only a test!

 

wheres the filter???

 

No..you wasn't supposed to ask that dreaded question. This was only a test.

But since you did....I..........er.......I um

There is a pantyhose clamped at the inlet of the 3" pipe.

DO NOT DO THIS!

At least now I know I can use a PRM filter to simulate the results. I needed to know if the stock intake was restrictive at all though.

 

damn ur crazy man. what if that pantyhose tore up and got sucked in? why don't u get the weapon r universal filter/cone and use the extendable cold air piping to route to the front damn?

 

Weapon R air filters suck! Or rather...don't suck well enough. See a test I did on my RAV4. ==> Weapon R Air Filter vs S&B Air Filter

Just sharing that there is some power to be had. Just be creative and make an intake that works for you. An intake with a reputable air filter.

 

pantyhose > weapon r filters

Impressive man, thanks for sharing!
Now I want to know how the 6 speed will do in a 1/4 mile compared to your CVT. The CVT has a considerably higher final drive, so maybe it will do a quarter mile faster, we'll see. The 6 speed LX is a bit lighter but I don't think it will be enough to make a huge difference.


I think the bigger restriction of air flow will be in the two catalytic converters and the twisty exhaust piping. With that extractor that Bisimoto is working on, that uses no Catalytic converters, you would probably hit 15's easy. Hell you could hit them now I bet with a perfect launch and perfect shifts. (I'm in no way questioning your driving skills, please don't take offense to that remark) But as close as you got to a high 15, I bet you could do it with a little more practice.


What kind of tires were you using, and what size???

 

185/60R14 General AltiMAX RT43 tires

BTW: The CVT transmission is one long gear. It doesn't shift, per se. Once the rpm gauge hits 6400rpm or so, it pretty much stays there the remainder of the wide open throttle run. Weird, I know! I like it though.

 

You are doing some awesome testing here..

 

Man this is exciting!

Only went one in my AutoX spec GD with best beeing a low 16.5xx @82-83. I have a manual and a 2 step thanks to FlashPro... Which is where I think there is a big difference. My 60' are LOW 2.4 OR high 2.3's. And that's with a crapton of static negative camber (-3.5°)

Considering my laundry list of mods, that you are already 0.5 faster in a CVT is VERY telling!

 

Saw some of your videos on youtube.

 

Wow!!! That's a little bitty tire, I'm not familiar with the specs of that tire but I will look it up. I'm thinking with a 195 or a 205 tire with a low tread wear will net you a high 15 for sure. I use Toyo R1R 195/50/15 when I autocross my GE, It's treadwear is 140 which isn't far off from a Hoosier A6 which I believe is either 60 or 80, can't remember. I think a tire like that on a light wheel like the Kosei would get you there no problem.
I'm curious though... How do you launch with the CVT? Does it actually take off pretty quick just flooring the gas? And with the traction control do you get any wheel spin off the line?

 

This is how I launch --> CVT Acceleration

No, it takes off very slow from a start. A rolling start or highway passing is a different story. I have my own way of trying to ....manipulate the throttle during start to make it almost seem like you are downshifting to 5000rpm+. I only do this with my feet on the accelerator. NO dumping of the transmission. Brake stalling the torque converter does not seem to make it take off any faster than just flooring it. Actually, most times it is slightly slower brake stalling.

With and without traction control, it seems to take off the same. I could not simulate results a mag got with the Civic CVT where they got better 1/4 mile times without traction control. All my times were the same.

 

I like the vacuum cleaner setup, very inventive and good use of stock inlet location.

Will definitely net higher trap, any added power is on top i'm sure. No filter helps lol

 

Very interesting test. Looks like in the 1/4 mile you got 2.3 mph.

What did it cost you in materials and time to accomplish this? Cost /Benefit?

 

It took probably 50-70 minutes for me to get all the parts and make it fit. I made three different intakes (See Great Intake Test Thread) in the parking lot of Verocious Motorsports in Delaware. If I have a silly idea, I just drive over there, open the hood, take the current intake apart and just start piecing ideas together. They are a warehouse that distribute piping, silicone hoses/bends, pipe heat wrap, etc. They are an intake/exhaust builder's dream.

I forgot the price as I always throw the receipts away. I only keep receipts of the intake I want to keep on the car. If I finish making one that puts the air filter in the wheel well, with the driver's side foglight removed, THIS is the intake I'll keep and post up cost to build, with the exact part numbers needed to make it work. This intake will have very little bends for air to go around and will only be drawing in ambient air temps.

Before this though, I need to read more on the maf sensor (I want a larger one). I called Maxbore earlier today at work and they said they can bore out the stock throttle body. So, I'm trying to source a used throttle body (next to impossible since Fits are next to impossible to purchase). Sigh!
