Pending my being able to take off work tomorrow night AND it not raining, I'm going to go for it.

From looking at a video of the 2013 Honda Accord CVT (189hp), it runs 0-60mph around 7.5 seconds and a 1/4 mile of 15.8@90mph. If I get my technique just right, I'm thinking I can possibly hit 15.8-15.9@89-90mph. I figure I'd call it out ahead of time, just in case.

The weight/hp ratio of the Accord CVT is around 17.6. With my car down to 2400lbs now, I only need to make 136hp from the engine. My CVT revs has to be in line with the Accord CVT's operation in Sport mode. I'm thinking I can do this. Woot!

Here's a video of the Accord CVT run.

Here's a video of my latest CVT run (Doing tests)

Everything seems to match up. Look at rpms/mph vs time in each video. Even up to 70mph, it takes both cars 10 seconds flat to get there. *Rubbing hands together*

 

Just need to get more runs under your belt. Once you hit 15s, what's your goal from there?

 

Run 14s of course. Hehe!

At Cecil County Raceway now. My 1st two runs were 15.9 and 15.8. Will post best two slips later. Gonna shoot for an ungodly 15.5 somehow now. It's getting cooler. ;-).

 

Once the aftermarket support picks up for the GK you'll have an easier time. Pretty sure 15.5 would be easily done with a little more power and a little more practice. Getting a good launch and staging in the right places, etc., will improve times. Stiffer springs to prevent squatting and traction loss would be the real ticket, though.

 

Points taken and thanks!

Here are the tickets from the night…. Mission Accomplished!! Our little rides can move.

 

Seems like you're pretty consistent. I know you're running some kind of aftermarket muffler, but what about opening up those pipes some more? Think about it: Be the owner of the first straight piped GK...

 

I autocross my fit and don't drag race but weight is of concern to me as well. Don't forget to take away fuel weight. When I autocross I usually run my tank with only 2 gallons. So that is saving 8 gallons of fuel. I have a 2011 base and my weight is around 1420 just by accounting for fuel and spare/jack and lighter wheels or in my case wheels that are as light as stock. The stock fit steelies are far lighter than the alloys. They weigh 30lbs with the stock tires. My aftermarket set weigh 29 total. That is most of the weight difference between the base and the sport close to 40lbs of extra wheel weight. A 13' fit sport weighs 1540 stock not 1520 according to the honda website when it was still showing it. So the base is in theory a faster car than the sport. Kind of ironic lol.

Someone actually once make a thread about dynoing a fit with an intake and exhaust once and it made close to 15hp extra but a week later it is back to stock because the computer retuned itself for better fuel mileage so to get the hp you will need to tune the motor. The sound should be worth 5hp alone lol.

I usually launch at 4k with my Dunlop ZIIs. That are 205/50/15. They are 23" diameter tires instead of 24" to give a 5% boost in wheel torque.

Dinan made an article talking about the light pulleys and recommends against it because they make the pulley lighter by removing the dampers which keep the engine vibrations damped at harmonic rpms without the damper your engine will damage itself over time. So so it with the understanding that you are shortening you engine life 10s of thousands of miles

 

Just because the ecu re-optimizes doesnt mean added power is removed.

you still have the extra power. its just not felt, since the ecu is massaging the fuel and ignition trims, making it as smooth as possible.

EDIT properly balanced light weight pulleys have ZERO harm on any motor. lightweight pulleys doing damage is a foolish myth, made from old GM guys who were stuck with ancient exterior balancing. All honda motors are internally balanced. There is not a single honda motor in factory form that isn't

 

H&R Springs have lowering springs for the 2015 Fit now. I just checked this out at Tirerack.

H&R Springs @ Tirerack

 

$210 is pretty good. Of course, getting them on there and getting an alignment is added cost (unless you do the install yourself. I'd rather get the alignment done the same time the springs are changed, personally.).
