Title: Exhaust mod ...
Post by: Smokinzx14 on November 14, 2013, 05:50:09 PM
Brock is having a sale on all Hindle pipes.. He had listed exhaust for the gen 1 zx14 .. I figured what the hell it might fit ( I was told it would not fit ) ... Well it fit great , I only had to do two little mods to make it fit .. Shim the lower rad bracket out and 1/8 of an inch and make a small bracket for the muffler hanger .. The extra power was much welcome .. It wheelies at will in first gear with a snap of the throttle and bang shift second it sets the tire on fire .. It's not loud at all , very deep tone but not loud .. I'm sure it knocked off a good bit of weight over the stock exhaust also ..

 ;D  I could not believe how small the factory header was compared to a stock ZX14R .. Looks like it should have come on a 600  and not a 1400 ... :o

How much louder than stock is it, when you are cruising? I like to listen to my tunes via blutooth and don't want to have the music drowned out by the exhaust.
I also agree with comment about the header pipes- they are about the same size as the pipes on my '80 GS 550e.

Not loud at all , very very deep tone on power , on cruising hardly any sound at all ..

pipe size ...  :o

Wow- quite a diameter AND layout difference (of course the layout difference will be the 4 into 2  for ZX dual exhaust instead of the 4 into 2 into 1 for the C14 single exhaust).  Thanks for sharing that photo.

What did you do for a fuel map? PCV?
So we now have several sources for an improved header. Muzzy, AreaP, Hindle and ZX14?
It would be nice to hear a few of these side by side or ride together at the Nationals.  ;D

Working on a P/C and mapping soon ..I may work with Don Guhl on this and have him do a fuel tune with the ECU  and skip the P/C  ..

Well seeing that i'm a racer and do lots of testing for aftermarket company's ,  I will do it just like I do all my testing .. I have base lined the bike totally stock at the track , now I will return to the track with just the pipe and NO tuning and see what we get .. Next will be a tune either by P/C or ECU ( maybe both ) and see what we get .. Some dyno time will also need to take place to back up the track numbers .. Once all that has happened I will need to do some street riding to make sure the mapping or ECU tune is spot on for a smooth riding bike..
  I know most of you guys are not looking for a drag bike, but I know you do want extra useable power on the street ..( don't we all ? )  :)

Looked into ZX14 TBs?

I have a set of new ZX14 TBs  .. are the C14 smaller ?  The zx14R are 44mm..

I just looked it up , the c14 are 40mm .... hummmmm might be some power with the zx14 44mm TB

Ok I got some weights for the stock exhaust Vs the Hindle pipe ... stock 32 pounds , hindle 8 pounds .. So there is a 24 pound weight savings ..   :)

Yes.  I dyno'd 161.5 RWHP.  There's more there, I believe that more air into the airbox is needed, but too lazy so far to further explore.

There's also the plugging the TBs where the secondary fly rod goes through, or knife edging the rod itself.  I want to say they have opened the TBs up to 48mm and did some polishing.  And of course, velocity stacks.  I can see 175 RWHP naturally aspirated before the ram air effect if only we can get the air to the TBs and a good tune.  When you speak/work with Guhls, ask them about upping the RPMs, color me wrong but I see no reason we can't get another 1k out of the motor.  But, it still comes down to air in.

Ok the numbers are in ... Best all stock 7.00 @ 101 ... With just the Hindle pipe 6.77@105.44

 Picked up over 2 tenths and 4 MPH ... Better than I had hoped for ... :chugbeer:

Maybe I am dense, but those C14 numbers can't be the standard 1/4 mile trap.  So what are they?  Stock C14 is 0-100 MPH in 6.8 seconds.... but I don't think that is what you are reporting either (or you wouldn't be posting speeds of over 100).

From my research, the best stock 1/4mi number (which I believe and was repeated) is 10.76@126MPH.

It's a 1/8 mile track  ...Based on my 1/8 mile numbers the bike should run 10.50s in the 1/4 mile .. I will be testing at our 1/4 mile track soon and report back ..

It's a 1/8 mile track

OK, that important piece of info does make quite a difference :)
