I have a 2006 Evo 9 with roughly 35,000 miles right now. Its basically stock except a cone filter/walbro and tuned @ 21psi. I got the car dynoflash dynotuned a few months after i bought it new....probably like 3 years ago.


I'm looking into doing a Greddy Ti-C comp turbo back exhaust and a boost controller and getting retuned. Are there any other supporting mods that i would need to do?(already have the walbro fuel pump)

How much can the stock clutch take? I don't want it to slip while getting tuned


Thanks

You should be fine, however it depends how you drive the car. Launching/ drag racing etc.

You're pretty much already at about what the stock clutch can handle. I wouldn't give it long. You might as well start saving up for a new one. Few people that do any modding or hard driving make it past 50,000.

Get a LICP, if not a full pipe set. You can find just the lower which makes the most difference for about $150.

Drove around at 440 whp and 400 wtq for a month and when i hit 500 whp and 460 tq it slipped ....lol...My guesss will be 400 whp and 375 tq all day with no lanching or power shifts...

yeah the oem clutch wont last much longer after you put a TBE on. My clutch started slipping 1k miles after I did all the bolt ons and a tune. Some other supporting mods you should look into is a LICP and a set of gauges(boost, EGT, oil press.)

yea but that most likely happened because of milage, not due to the mods.

Everyone is different and it depends how it is driven.

The OEM clutch can handle 350 and a little past 400 awhp. It depends how it is driven which makes it go bad. Adding an exhaust and increasing hp will not necessarily cause it the start slipping.

The OEM clutch will work at those power levels however, the whole point of the clutch is to transfer the power to the ground. So the stronger the clutch the better the job it does.

I have a friend with bolt on evo with oem clutch at 75k miles. I am at 45k with bolt ons. Others see a brand new clutch go bad because how it is driven.

I've had my car since around 64,000 miles and have never changed the clutch.

But then again, I have only launched it about 2-3 times.

Get a new clutch and PP installed! You will be AMAZED at how much better it is! I'm in the same area you are HP wise and when I got mine replaced it was like a new car again! My old one was the same way as yours is now. If you think it's doing ok you would be wrong! I thought the same thing before I replaced mine also.

I went 24k on my stock clutch with no restrictor in the slave and made 200+ passes at the 11.50 level. It was thoroughly done at 24k though. Never slipped but wouldnt shift at high rpm anymore.
