hi there... i was thinking in few mods to EVO X...

what should be the MAX HP's at the crank that a TOTALLY stock ENGINE and DRIVETRAIN can RESIST?!?!?

any idea!??!


thank you for any feedback!

 

The stock clutch wont take much power over stock for long.

 

come back with this post in ... oh..... at least 6 months.. cuz honestly dude, they are just starting to tap into the engine. I would also like to say that fromthe looks of it, the ones that are going to push the 4b11 are doing it low and slow, making sure they do it right the first time.

BIG props to Buschur, AMS, Vivid, those pesky PR guys :P, and everyone else doing it so us customers get the best gear for our car


^^ shameless plug for you all... toss me some stickers at least :P

 

thats not entirely true... the stock clutch wont survive many repeated stock launches, let alone high HP launches... but if you drive it normally it'll take the power

 

huh? can resist? do you mean handle???
The stock clutch can't even really handle the stock power.
Guessing on the motor you won't want to push it past five or six-hundred horses.
Anything past that, or really near that, I would balance the crank/rods & pistons, port and polish the heads and port match the intake and head gasket, replace cams and gears. and AMSOIL is a must. Past the engine, go to a new clutch/flywheel combo, aluminum drive shaft, etc.
I haven't looked yet, but what type of clamps do we have on the shafts & axles? Depending on answer that might need to change along with the clutch/flywheel combo. I'm also not sure if the frame will need re-inforcement (like sub-frame connectors and ladder bars on a F-body) to keep from flexing/ twisting under high torque, or weight transfer putting odd flex on suspension.
I think the X is definitely fragile, but very upgradeable. I just want to crush a GTR on "Tail of the Dragon" or some uphill climb or something.
I would worry about suspension first though. This thing is screaming to mount a laptop with some PC controlled Tiens. Throw un an adjustable alignment kit, pillowtops, lower control arms etc. Some wider rims and stickier tires, sway bars etc. and really highlight what the X was made for. This thread makes me want money. I need money. Lots of upgrades needed. I'm druelling thinking about this setup and just getting steamed that I can't do it all now... Oh well, at least I have something to look forward to.

 

What experience do you have with regular driving on a modded EVO and the stock clutch?

 

idk about Gexxer, but my clutch wento out at 2700 miles. This thing wasn't made to handle mutch, mitsu wants the clutch to wear so much faster than everything else that there is no chance to mess up anything serious.

 

Not trying to start a war or anything, but having to replace a clutch at 2700 miles is either a defect from the factory, or you are riding the clutch like crazy! Maybe even launching from light to light and slipping the clutch.

 

The war has started lol. I have basic bolt ons and mine went out at 5,000 miles on it. Now i have an ACT and its awesome. The stock clutch had about 10 maybe 12 launches on it.

 

I have two step launched my car oh... at least 10 times in the last two weeks.. not back to back, but all were full pulls to redline in 4th. My clutch is still perfect at 4200 miles on the car. I plan on replacing it in the very near future, so it doesnt really matter to me.

as for knowing about modded evos on stock clutch .. not much but i had a modded 91 GSX on the stock clutch ( ok so it was an OEM replacement, sue me ) till the 3rd cylinder let go.. and i beat the **** out of that car. I'm pretty sure its not the same type of clutch in the VIII or IX, but a stocker is a stocker.

RGUY " What experience do you have with regular driving on a modded EVO and the stock clutch? "

I was referring to the fact that you can burn the clutch out in three BtB launches stock, as done by a good friend of mine on his X. and that even if you put power into the X you can use the stock clutch if your not abusing it. I should have been more clear in what i was saying there. I'm not advocating the stock clutch, I feel that it should be one of the first items replaced in the car.

 

I would agree about the factory defect. The factory clutch is a defect. I have driven a stick for 15 years, and never burned one up. The flywheel was burnt blue (like titanium tipped exhaust). The clutch was like purple, and had like a granite/marble swirl look to it. It was insanely cooked and was slipping b/w 2k and 5.5k RPM. I only launched it once and it smoked at me then, and I had the smell prior to that even. I never rode the clutch, so for this thing to have gone out that fast, that tells me one thing: It's garbage. Can't wait to get the ACT, but I want to finish bolt ons, computer mods, and suspension before I start getting into mechanical stuff. I'll prolly do the clutch flywheel along w/ a six speed dog box and drive shaft.

Also, bump for question regarding what type of joints are on the axles. I don't feel like pulling up on ramps just to look if someone already knows.

 

It will be interesting to see just how long the stock clutch holds up to basic bolt ons and a tune.

I had 34k miles on my VIII, probably less than 10 hard launches, 7 track days and a bunch of hard back road driving. Stock clutch was still in it when I sold it and it was holding up just fine (Vishnu 1+ tune making 290whp). So, I really think most experiences will vary.

We a few mods ours was done at about 2,500 miles , the ACT unit we have in there now seems to be doing great so far .

 

[QUOTE=xtremeboost;5804541]How long was the car modded before the stock unit went out? Also, what type of driving were you guys doing?

From what I remember the clutch in the 8/9s were also given a reputation for being really bad...but I never had an issue. I guess it really depends on how the car is being driven. My main concern at this point is being prepared as I'm planning on tuning the car as soon as ECUFlash is available.

Our car was modded at 320 miles We pretty much took the car to the track every chance we had . But we did notice that the disk its-self seems to be a bit cheaper material then the 8 or 9 - not sure because we have not actually tested it at a LAB but it just looked cheaper . We just seemed to have way too many big pieces inside the tranny bellhousing . The first time I felt our clutch slip was from a 2nd gear roll and that was at about 25lbs or so .
