They released this new master cylinder about 2 weeks ago, any one has it yet? how do you like it? I order mine a couple days ago, and it should be here next week. just want to hear some reviews about it

 

Wow, I didn't know they released one for the s2k! How much was it? Where did you get it?

 

I got it from a Vendor on Honda-Tech, 179 shipped.

 

Give us some feedback,once you get it installed;pros & cons.!!!

 

What's "special" about this thing?

Omni-Power Quicklutch Master cylinder.

The Omni-Power Quicklutch Master Cylinder works by reducing clutch pedal travel by nearly 50%. This is accomplished by changing the Master Cylinder Bore size from 5/8 inch (approximate 15.88mm) to 21 mm in diameter. The master cylinder has been independently proven to reduce both lap times and 1/4 mile times measurably by reducing shifting times. Each master cylinder comes fully assembled and ready to install as a direct OEM replacement.

Key Features:
5 year warranty
.2-.4 reduction in lap times (track dependant)
.1-.2 reduction in 1/4 mile times
Reduced shifting time
More positive shifts
Increases clutch life
Reduces tendency to miss-shift
OEM seals
Rebuildable/serviceable by OMNIPOWERUSA.com
Works with any clutch
Direct OEM replacement
Improved synchronization between short shifters and clutch pedal
U.S. Patent pending design

 

Interesting! I'm sure that some of those points are advertising hype, but nevertheless, the principles are reasonable. The only thing I see as a drawback is the need for more clutch control when starting off. By nature of this product, clutch engagement will be short and brief.

WTB - let us know what you think. I'd rather hear from a real S2000 owner than advertising hype or even a bunch of unknowns driving other kinds of cars.

 

I will let you guys know my opinions when i have it in; i hope it can solve my engagement point problem.

 

After reading this thread ill add a few things to help people better understand our Quicklutch master Cylinder.

In a stick shift/manual transmission vehicle such as the S2000 there are 2 mechanical devices operated by the driver that need to move X amount of distance in order to complete a gear shift.

That being said, if the ratio of movement for each one is disproportional too much then the faster movement will always be waiting for the slower one. causing missed gears

In the case of the clutch master cylinder and the shifter:
the shifter moves about 3 inches stock to transfer from 1st to 2nd gear. The clutch pedal needs to move about 5.5 inches. If you install a short shifter you make the 1st to 2nd shift about 40% shorter.

the stock pedal travel vs shifter travel is roughly a 1.8:1 ratio on the stock S2000. after installing a short shifter of about 40% less travel (about 1.8 inches) it changes to a 3:1 ratio. Meaning the clutch pedal has to travel 3 inches for every 1 inch the shifter has to travel.

By installing the quicklutch master cylinder the travel is changed from approximately. 5.5 inches to 3 inches.

with the stock shifter the ratio changes from 1.8:1 to 1:1.

with a typical short shifter the ratio changes from 3:1 to 1.66:1 (assuming 40% shorter than stock)

adding a short shifter and not changing the clutch master cylinder ratio/travel will only promote missed gears as the synchronization will be greatly affected.

I hope this better explains how this product works and its importance.
