my bad

 

Here's one of my favorites:

"Zeroing the Knock Retard table as a solution for detonation."

Im supprised at how many people do this that claim to know what they are doing when it comes to tuning.

 

Gotcha got hp, and I know we were in agreement.
I was just giving a bit more background to my case. My girlfriend at the time also noticed a distinct difference in braking with the new setup. So I know it wasn't just in my mind.

And I agree Rich, the terms just seem to get thrown around way too much with little regard for what they really mean. I believe it's even worse in the computer industry but it stems from a lack of understanding.
Check out some of the magazine articles. Some of the "tech" guys are even confused. How many times have you read.... "Swapping to the higher ratio rocker not only increases lift at the valve but adds a degree or two of duration"? I wrote in to Car Craft magazine here a couple of years back to make a correction on this point..... I never heard anything back from them.

The misinformation runs rampant on a great many things but with everyone and their grandmother using the internet there's no dout that the shear volume of information from those who should really just read has alot to do with it.

I can see how it would add a degree or two @ .050" but it wouldn't add any advertised duration. Reason being is the cam would hit .050" earlier with higher ratio rockers.

 

wont adding 1.6 rockers increase durration at .050? you will get to .050 faster, no?

when the 1.6's is the same pysical spot on the cam as the 1.5's .46xx lift

total durration of the cam wont be effected obviously- 0 x 1.6 is still 0


As far as the brakes MG-
i'm sure there is a differance other than coating. Perhaps they were high carbon rotors?

Less therm mass, less frictional surface but yet you stop faster? maybe its in your head because even baer themselves say they wont stop any faster.

 

Zinc wash is only there for corrosion resistance. And HC.... I don't know, but Baer doesn't make mention of their rotor being an HC rotor like Brembo's "special" HC disc. Seems that that would be a good selling point so I'd just assume that they aren't.

Anyways, yeah they stopped better than the oem discs they replaced... as I said.

did you do braking tests or did your *** tell you so? The mind can play silly games with you- no pun intended. Z06 has some very agressive brakes as is, it would be hard to note a change without some kind of testing.

Kind of like when they drop in a K&N filter and say "OMG!"

 

F-bud: your post addresses the confusion I was trying to clear up. "Duration" is defined at the tappet (lifter), not the valve. So there absolutely no way a change in rocker ratio will change "duration". That's why I used the term "dwell". I was trying to differentiate valve events from tappet events. So, you are absolutely right, that the valve will be at 0.050" (and greater lift) longer longer with higher rocker ratios. But that is not "duration at 0.050", since by definition duration is in terms of the motion of the tappet.

The effect on performance of using higher ratio rockers is similar but not identical to adding a couple of degrees of duration.

No *** meter to it. I race at the same track every weekend and I knew how much distance it required (using a pylon as reference) to brake the car to safe speed after the run. The distance was noticably shorter after the change to new discs.
Like I said, it's not just me who noticed the difference so who knows. You're the "brake expert" not I kiddo.

Let's not go off tangent to this thread... if you have anything else to ask you can e-mail.

btw, this was not a Z06... just an M6 coupe.

tag, your it "kiddo"

 

The brake thing again.
WHO CARES!!!!!
If slotted and drilled works for me then just let it go.
Its my money and if I want to waste it then I will (don,t think I am but....)
Mindgame is drag racing Trey, he very well could be seeing a big difference hauling that car down from speed with his "Oh GOD there awful" slotted and drilled rotors.
This is a question of money, period. You say its a waste I say its not.
Could we quit bickering over other peoples money now?

 

i think its over performance, or a lack there of.

 

Thats debatable
Obviously.

 

FWIW, about the '93s and FP... they will adjust to changes just like '94+ because the PCM operates the same way (anything that brings the car away from 14.7:1 AFR will cause the BLMs to "fix" it). It has nothing to do with the MAF sensor, which is why '93s are affected too.

 

Hmmm I was under the impression that the coupe and the Z06 shared the very same brakes. I'm looking into swapping the C5 setup onto my car in the future using Bob Bishops brackets or an equivalent. Not necessary but they are far more agressive and far better designed brakes than the stock LT1 setup.
