I'm tryin to build a 500 HP or more Turbo Civic, and someone told me that i'm gonna be going thru Trannys like notin ( In other words blowin them). Is this tru? Supposely becuase its too much HP.

 

No.

Just don't launch it with 28" slicks and you'll be fine.

 

If you're asking that then I dont' think you know what's ahead of you at all. do a search for cars taht have 500 hp.

 

So... you are planning to run a tranny that came with a car making 130hp max on a car making 500hp or more........

Let me put this another way.....If/When you work out, what do you bench? Take that, multiply it by 4. What's gonna happen when you take that bitch off the bar? Yeah... that.

BUHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAHHAH!

There's a slight problem with your comparison...I'll let you guess what it is first...

 

I'm way too tired to guess..

 

Whoever told you that is prolly into domestics or DSM's, hehe..

I made over 35 passes on my bone stock tranny @ over 600hp.. blew up once..

If you say thats "going through trannies like nothing", then i guess it is....

i know alot of people who do 500hp+ on stock trannies. Its almost comon practice for people, except for some of HT's rocket scientists

Looks @ RevenantAE's AV. No wonder! LOL!

But to elaborate more on the subject, there are quite a few examples of 400-500whp Honda's running stock trannys. SixtydashONE is a prime example, along with a few other SFWD guys too.

Yes, the transmission was designed with a motor that makes 130-160whp. But that doesn't mean that it's the total maximum amount of HP and/or torque that it can take. Abuse and stress is what limits the total input that a tranny can take. Launching on slicks produces a ton of stress to the gears/axles/etc etc. So yes, it will break, eventually. But if raced from a roll, then there is significantly less resistance.

You were comparing metal vs. muscle fibers. Mechanical parts are designed to accomodate various levels of stress to ensure reliability, in otherwords: overbuilt on purpose. Muscles, on the other hand, adapt to stress. Apples to Oranges. But nice try though...

 

Also, driving style will ultimately decipher the lifespan of these parts as well..

If you drive your *** off, they will last longer.. This means, Not too much driveline shock, no dumping the clutch, and various other lifesavers..


EDIT, haha, i didnt even notice his avatar, damn, that was a good guess

But it's true! (I own a 90 Talon Tsi myself, and it's been good to me....so far)

Actually my DSM was damn good to me while I had it. 3 years, and only 1 break. Now gas mileage..... dear god.... the gas mileage.

Anyway back to the analogy discussion. The analogy was accurate, what happens when something (either you or your tranny) is subjected to more force than it can handle. Bad things.

I'm sure there are people running ***-loads of power on stock trannys. However, to say "lookie there... Bob does it, so it's all good" is a pretty bad idea.

Let me draw a comparison to another Honda strength issue... stock rods in a D series. When you hear people talk about boosting it, there are a wide range of guesses as to what boost/HP level is "safe". Some say 5psi, some swear 7, and there are always guys who say "I've been running 10-12 for EVER with no problems".

My point here is this. The tranny MAY handle 500hp. Then again it may not. There are plenty of tranny failures posted on HT that aren't anywhere NEAR 500hp, so I see it as a disservice to the original poster to try and convince him all will be well when that's really up in the air.

 

Since you think its such a bad idea, i would like to hear what you suggest those people running 500+ hp to do.

 

The beauty of building street hondas, is that more than likely someone has already done all the testing for you so the guess work is done. It would be a disservice to the H-T community to throw all that experiance out the window

That's the thing, it's not just bob. It's everyone in his town...

btw- I have been running 10-12psi on my stock d16 for 19,000 hard miles.

Good question. Also what exactly breaks in Honda trannys when they "blow" from too much torque?

The question wasnt really meant to be answered, mainly because i dont think RevenantAE has one
In reality, there really arent many choices for aftermarket trans/parts simply because the honda croud doesnt suffer the exploding tranny problems that DSM and other people do.. Thats starting to change though, because more and more people are puting down huge numbers on the street, and of course the trannys do break from abuse and power as was already stated. THe most common thing to go IMO is the stock differential.

Check out http://www.gear-speed.com for some options. They have a pretty decent selection from what i can tell, such as custom gear sets, spools, LSD, etc. I decided to try out a set of their carbon syncros they're selling.

 

That is one thing I miss from my Honda, switching to the Subaru...
I worry about the tranny too much. I tripled the output of a stock 1990 LS transmission, and it was fine. Drove it fairly hard also.
It is my opinion that FWD is VERY forgiving on trannies due to the amount of tire spin they produce, that would all be horrific driveline stress if you had slicks mounted. Honda Trannies can handle alot of abuse.

AWD on the other hand.. It just scares the crap out of me when I see someone mount up 4 sticky assed tires, a grabby clutch, and stiffer motor/tranny mounts then proceed to rev up to 5500 and prepare to drop the clutch on their stock tranny.
Gives me the *******...
