EDIT: I Split this thread into a new one since it strayed so far from the original thread.


Im going to pick it up now - :D

My mechanic said he freaked the neighborhood out when he test drove it. LOLOLOL


Dynotune tomorrow am - Videos and dyno slips to follow....

Those strut rod bushings are made my Moog. I just did the strut rod bushings that attach to the control arm on my old '95 today. Got 'em from RockAuto.com
 
Yes, those strut rod bushings are very good, high quality parts... I had them on my 95 LSC.

Yes and no. I too believe the average driver won't feel or benefit from these kind of rotors and they are mostly for looks. However I do believe in a track/road coarse type condition they breath better and therefore stop better over the duration. Less brake fade after repeated hard stops. Just like all performance mods, there not going to last as long and have draw backs. Brake pad wear, cracking, etc.

I do believe they are probably proven many times over to out perform stockers in performance braking situation.

But what do I know about anything.


I came across an article that explained why you would want slotted rotors. The slots allow the gasses that are developed from hard braking to escape from being squeezed between the rotor and pad. Without those slots, the gasses escaping will cause the brake pads to "chatter" as the heat and gasses escape from the friction.
The cross drilled is somewhat the same theory, as well as rolling mass reduction. The technology and race theory is for the guys who have dedicated cars that race on twisty tracks for many miles and hours. Not for the cats who drive to work, grocery and back home.
They sure are pretty to look at though.:cool:
 
Drilled/slotted rotors DO NOT outperform blanks. Period.


I own/operate an SCCA Improved Touring E-class Mustang. This car will repeatedly stop itself from 165-170 mph every lap at Firebird main course (about once every one and a quarter minutes) The brake setup is as follows:

Cobra calipers (yes, the crappy PBR ones)
Very solid brake ducting
Very good (expensive) DOT 4 fluid
Hawk Blacks or SBC race pads


...drumroll...


and Brembo blanks.


The outgassing mentioned in this thread is not a problem with modern brake pads. Drilling/slotting rotors does the following:

1. Decreases the overall mass of the rotor, thereby reducing its ability to absorb/dissipate heat.
2. Increases pad wear by the holes/slots digging into the pad
3. TREMENDOUSLY increases the chance for the rotor to crack
4. Disrupts the natural strength of the casting because there are now additional stress risers.


If any of you spend any time at a road course, you'll notice that even on uber-racecars, blanks outnumber drilled/slotted by probably ten to one. The only people that have drilled/slotted rotors are (especially) the Porsche guys because those holes are actually cast into the rotor.

If anyone of you don't believe me, feel free to view this thread:

This is the 'infamous' thread saved for posterity by corner-carvers forums all about this subject. The folks at www.corner-carvers.com are, IMHO, one of the best no BS locations for hardcore tech on the internet.





With that said, I have drilled/slotted rotors on my silver mustang. Why? Because they look cool. :D

248 rwhp
241 rwtq


252.83 RWP

I cant give an exact on the Torque because the graph screwed up a bit at the end and shows 287.78, which is wrong. But it looks like about 254 RWTQ


Cant say I know much about these things to be honest, but I bet I'll be learning alot shortly. I have videos, but the camera is in the car and im too lazy to go get it right now. A little later.

One interesting thing, is that it appears I have gained in gas mileage. I cant say for certain, but it looks like I picked up about 3-4MPG so far. That may not sound like much, but at 1 tank of gas a week, thats a savings of about 2-3 gallons of gas per tank, and 300-400 gallons per year. So at todays gas prices, it was well worth it to have the tune done.
 
Here are a few shots from the dyno today....

The second set of pics are a car they are working on that looks like it will be quite mean...


Videos to come soon.

Nice numbers Joey... what rpm did you make peak horsepower at? Is that a twin turbo LS1 engine?
 
Congradulations Joey. I like your front plate. Arent you lucky you have gold members ....:D
Yea I too like that impala 59 or 60 allways like those body styles. That thing must be a rocket:eek: :eek: :eek:

Can't say I have ever experienced any of those negative effects. I've got 40,000 hard driven miles on a set with no negative effects at all. Nothing is different aside from them actually lasting this long.

The racing info is nice and all, but brakes using racing pads will always react differently that brakes using street pads. A good racing pad can make even the most underequipped braking system work quite adequately.

Different car and motor I know, but my gas mileage went up when I went from 3.27s to 4.10s. The motor spends less time lugging around and more time in the power band.

Nice numbers, dude!
 
Hey Joey..

It was a pleasure meeting you and tuning your car. I am pleased with the results. If you had stayed 5 minutes longer, Glen with the Mark8 showed up. You guys could have talked about INTAKES!! As I told you, let me know if you have any issues or want to change shift points. I will get that taken care of asap!

As far as gas mileage, it sounds like what I told you. The computer was trying to compensate by pulling 25% fuel (max short term) prior to the tune.. Now the short term trims are right in line and the WOT was leaned out 10-11%..

I will get you the electronic dyno sheets on tuesday.

thanks bob

You did a great job Bob, Thanks!

ROFL! Honord huh! Well thank you. Im in Shaumburg frequently. Usually up at Woodfield Mall.
 
GREATFULLY BOWS, woodfield huh? been there a few times all i rembered was it was HUGE and i think we then went to Dave and Busters and after that i dont rember nothing (dont worry used a d.d.) could u pm me the # to the place in byron i tend to whore myself (w/labor) ot pay for goodies and with this place just up the road it is possible, very possible!!

Number to what place in Byron??

252.83 RWP

I could kick myself if you got that number off the 2nd or 3rd pull.
How many pulls did you get.

I was going to post a 252 number if you got more than 1 pull because the guy would have got that with the tune.

I posted the number but then pulled it fearing I would look like too much of a know-it-all. I also had the 2nd gen intake holding down your rwtq numbers. Looks like that intake is not as horrible as it seems compared to the Gen 1.

Are you going to b!tch slap Driller at Carlisle now? :eek: LOL :D

2nd Gens rule. All you 1st Gen guys can just sit and drool.:cool:

P.S. Joey, was that number the 1st or 3rd pull? If the 3rd, what was the 1st number.

I think you are talking about me... I live out in Byron, BUT I am a mobile tuner... Ive been tuning and racing cars for over 15yrs... If you are interested in a dyno tune, I use a dyno out of Machesney Park for people in this area.. If anything else, please PM me.

thanks bob
