After reading and thinking about it, I just ordered my Mythelogy.

But I still have some questions about these lightened pulleys, namely, if it is proven good, why are motorist not using them. I mean, beside manufacturing cost, iron vs high grade alloy, what refrains such a great motorist like Honda from implementing this technology into their small engines?
Is the extra manufacturing cost not worth anything, marketing wise?
Here I have a few thoughts on witch I would appreciate comments :
-The pulley upgrade will not increase the rated power, wich happens to be THE manufacturer reference used by competitor and car reviews (it will remain 109HP, won't it?).
-The time required for the 0-60 will remain above 11s, because most torque gain is at lower RPM and is felt mostly in 2nd and 3rd gear. If that is true, then this frequently used reference (0-60) is not bettered significantly.
-The pulley is not very well protected from bad road hazard and could be more easily dented, therefore unbalanced... thus leading to superior warrenty repairs?

If none of the above make sense, then why are Honda does not implement this upgrade as a standard feature?

 

Isn't the pulley protected from road hazards by the engine under covers.
And the pulley has been heat treated for strength. And has a hard anodized coating to protect it.

 

Honda has to deal with the desires of loads of different drivers with different ages, styles etc. so they have to make all their vehicles Quiet, Smooth.... I agree that Honda and other car manufacturers might have taken this in account when they designed their OEM pulley.

In the same line of thinking, the weight of the pulley is in direct corollation with the inertia: a mass of 4 lb spinning at over 1500rpm will accelerate slower than a mass of 1.3 lb of the same diameter, but will decelerate much slower when the accelerator is released.

My other question is: Will I possibly experience "jerky" motions in Stop/Go city traffic once my Mythelogy is installed?
I wish to have impressions from those who have done the mod

 

I am having mine put on tomorrow so i will update after i pick it up. My mechanic said that with a/t's their is the potential of rev slipping (not sure the technical term) but he has not worked on a L trannie or with this pulley. We shall see. Maybe being the pulley is balanced and dampened it will have a better effect.

Anyone else have an A/T and have the myth pulley installed yet?

 

I noticed that the dyons for the Fit/Jazz have CVT in the name so they must be for the CVT Transmission. Not available in the USDM Fits yet for those that thought it was the standard auto trans. in the dynos.

Also there was 1 dyno in this thread that showed the peak hp and torque to be in the low rpm range. That looks more like a dyno for a i-dsi power curve doesn't it?

VTEC has the power and torque in the higher rpms where i-dsi has it in the low rpms. Right?

Just my 2 cents.

 

No jerky motions on my sport a/t.
And its quieter then summit pulley.

 

hey jimmy i thought you had a manual?

 

Nope, sport a/t.

 

ok folks...just picked my baby up. Sport a/t. Let me tell ya that this mod was well worth it! Engine runs smooth. Much better throttle response. revs much faster. No problems with slipping or noise whatsoever. The engine is much more vocal when the vtec kicks in.

THANKS Jimmy for hookin me up!

 

I'm glad you like it!

 

Did anyone else try going to the web address they have at the bottom on the big black ad for it? Mythelogyracing.com

I come up with a web address parking page. Nothing to do with the pulley.
Strange

i-dsi??????????

 

i-DSI then. Here it is.

Depending on the region, the Fit is equipped with either a 1.2, 1.3, or 1.5 liter i-DSI engine, or a 1.5 liter VTEC engine. Reference from http://en.wikipedia.org/wiki/Honda_Fit

And this one.
Two different valvetrains are present on this engine series. The L12A, L13A, and one of the L15A varieties use i-DSI, or “intelligent Dual & Sequential Ignition”. This setup utilizes 2 spark plugs per cylinder. They fire at different intervals during the combustion process to achieve a more complete burn of the gasoline. This process allows the engine to have more power while keeping fuel consumption low thanks to the better utilization of gasoline. Emissions are also reduced. The i-DSI engines have a modest redline of only 6000 rpm, but reach maximum torque at mid-range rpm, allowing for decent performance without having to rev the engine at high speeds.
The other valvetrain in use is the VTEC on one of the two varieties of the L15A. This engine is aimed more at performance than efficiency with a slightly higher redline, which reaches peak torque at higher rpm. However, it still offers a good combination of both performance and fuel efficiency. Both the i-DSI and VTEC have relatively high compression ratios at 10.8:1 and 10.4:1, respectively. Reference from here. http://en.wikipedia.org/wiki/Honda_L_engine

 

I have Summit pulley in my City which is 1.3 AT, and the results are good, you get better response and the rpm revs faster, but if you are AT it will not give you more top speed.

 

Website working fine ....
the main website is actually www.mythelogy.com

 

But the one at the bottom says MythelogyRacing.com which doesn't work. Like I said.

A search for Mythelogy Racing turns nothing up as well. If it doesn't exist it a myth and shouldn't be on the ad. It's misleading plain and simple. If it does exist then where is it?

 

try www.mythelogyracing.com

 

so this would up mpg too ima have to get that

~edit~
i misread @_@ that was a review for the Perodua Myvi 1.3 EZi Owner

but do you guys think it will still up the mpg in the fit?

 

Hey Jimmy101, I'll take one!

 

A redirector page. Too funny. Has anyone tried this on a MT yet?
