ACPT Carbon Fiber Driveshaft Mazda RX7 93-97

ACPT has developed a carbon fiber driveshaft that allows a 1000 RPM increase in the engine speed and gives the engine a chance to work at its� power peak. Its track tested at well over 800 horsepower. Its a stronger,lighter, direct replacement for your stock aluminum driveshaft. Which are known to twist.

You can achieve rear wheel horsepower gains of more than 5% with the simple switch to an ACPT carbon fiber driveshaft. Carbon fiber offers you more strength to resist extreme torque than steel with about half the weight. Just like the common use of the lightweight clutch and flywheel units, a lightweight driveshaft allows more of your engine�s power to be applied to the ground during acceleration.

In addition to minimizing rotational power losses, carbon fiber�s unique vibration dampening characteristics also help improve power output.

Try thinking before you speak n get some facts on a particular item before you speak some bullsh1t about it. I listed the website for one reason...which was to look at it for yourself if you had any fuqin common sense. Now take that sideways @ss bullsh1t and say it to someone else that aint ganna stand up for what they sayin. Cuz trust me when i tell you...you DON't wanna flex on me. I try to be nice as i can be on the regular cuz its the right thing to do, but don't get it twisted fool, like everyone else i got some wrong in me too.
I wouldn't consider anything vivid says as 'fact.'

From ACPT's website:
Driveline vibration is a common problem that can limit RPM. ACPT's involvement in racing began in 1986 when Dan Gurney asked us to apply our expertise in aerospace composites to solve a vibration problem with his IMSA GTO Toyota Celica. In this front engine, rear transaxle race car, the driveshaft ran at engine speed. The metal driveshaft was experiencing harmonic whip, limiting usable RPM and forcing them to run the engine well below redline in each gear. ACPT developed a carbon fiber driveshaft that allowed a 1000 RPM increase in usuable engine speed and gave the engine a chance to work at its' power peak. Gurney cited the ACPT driveshaft as a major factor in winning the 1987 IMSA GTO Championship. Since 1987 many racers in all areas of motorsports have discovered the extra RPM and the resulting tuning flexibility carbon fiber driveshafts provide.
How do you like those apples? Don't come into Race Car Tech acting like God after browsing a parts catalog and playing Gran Turismo.

MiKEdaG0D: Dude, chill out. Think about it, how could a drive shaft that isn't directly related to engine speed, but vehicle speed allow the engine to rev higher? RX7s aren't set up like Porsche 944s with the trans. located in the back of the car. The lighter drive shaft would allow you to accelerate faster, sort of like replacing heavy wheels with smaller lighter ones. See what I mean?

Edit: D'OH! Eastcoastbumps beat me to it, lol.

I run my engine to about 12K on my Drag race p-port motor.The assembly has
to be really balance to stay up that high,also the oil system has to be upgraded
to withstand the high volume to the bearings.I have taken my engine apart and
don't see any problems.I encounter bearing problems before but i do really have
to keep an eye on the oil changes .

Wow. What can I say to that?

As was pointed out, the claims on the website are BS, because this shaft is not being used between an engine and transaxle, but rather between a tranny an diff. Big difference.

Too many off those performance shops are and their web pages are complete BS, as has been shown over and over again by people who actually race. A healthy dose of skepticism is in order whenever you start reading these claims. Put the brain in gear and think about what they are saying.

As for the language - let's just try and act like adults here.

i think we should have an intervention with that individual who mentioned the super cool driveshaft and suggest some anger management. Breath in......breath out......repeat. MIKEdaGOD takes his name to seriously. We all know that you have to do just a little (drastic sracasm) more than a fancy driveshaft. That alone is one of those things that is so rediculous is hurts my brain to think about someone who actually thinks that.

And let us remember, just because it is on a website doesn't mean anything. If everyone told the truth about a product they were trying to sell then that would be a different story. Newsflash Mike.....the internet is not a reliable source. I bet he believes all those email about how to make his weiner bigger too.

How many "credits" is that "mod" in Gran Truismo anyway?

Ok I'll be a man and say im sorry for the tiitty attack, but you gotta understand where i was comin from. I didn't know the fact about the driveshaft being between the transmition and diff and was just goin on from the information i was given. I apoligize for the temper and the language but at the time it did get me hot that you came at me like that like I made the product and didnt even look at the website either. I would of been nicer if someone would of claimed the website as bs and not single me out like i made the ****. I will admit I'm still in the process of learning about these cars myself and my fault for taking your knowledge for granted. Maybe i should do a little thinkin before i speak myslef eh? I'm not here backin down from my comment earlier and don't get it twisted, I'm just being a man about things a admitting i was wrong. But agian my fault for the childness but again you gotta understand where i was comin from and yes your right, lets act like adults here. Stay up, stay strong, and most of all be easy

You were singled out because their comments were in direct response to one of your own.

You also dictated the tone of others' responses with your:

In your own words: dumb @ss.

Crap like this only seems to happen every few months in here. Let's keep it that way. Thanks guys.

No harm no foul. It takes a mighty big man to appologize, especially over a website since all the anonymity involved. No one on this website knows everything, but there are some who are pretty damn close, most have forgotten more than I will ever know about these devils.

To get that kind of revs, you need to start with the engine and make sure it can acheive/handle that before you go for the trick exotic carbon goodies. IMHO they are the final componants and won't do a whole lot in the actual increase of rpms, just how much faster you get up there, I would have to imagine that is a substantial rotating mass reduction.

Anywho....all is forgiven. It is a vary admirable trait to be able to admit fault and will get you far in life, but it's best if you dont put yourself in that postion in the first place.

Rock out Mike....
