DCT and meth?

335is808 · 04-17-2014, 01:30 AM

hey guys, just had a quick question that wasn't fully covered in searching the web. Getting used to the power of fbo... so im very tempted to go down that meth road to kick me over the 400whp mark, the IAT drops would be awesome too since hawaii is pretty hot year round. I know meth comes with the massive torque curve output so i was wondering if the DCT trans was able to handle it reliably (for years). Im already losing traction in 2nd gear sometimes, will LSD be needed as well or will it just be a luxury addon (I dont track). Also, is there a cheaper meth kit available for cobb? The hsf is nice but i dont want to spend a grand just for meth..
Anyways, hoping there are some DCT meth users out there willing to chime in.
Basically, Dont want the power if my car cant handle it reliably.

no one? ...

You'll be fine with meth but as far as kits go, Aquamist is your best option and it's worth it!

You won't need a LSD (even though it's the best upgrade from what people say) but you'll definitely need better tires. Nitto 555R would be a good choice for daily.

You dont need meth to get over 400 whp on N54 DCT. If E85 is easily available and properly tune you will get well over 400 whp.

If you do not have easy access to E85 then well I guess you have no other joice but to use meth

no e85 or 93 octane in hawaii sadly... meth is the only option for me but im sketchy at the strain of the massive amount of torque might put on the tranny.. is your IS meth tuned?

Im more worried about the strain it might put on the dct tranny than gripping the ground. Any other combinations with cobb beside hsf? Really dont want to spend $1000 if i dont have too..

if you're not going to do it right, don't do it at all.

Aquamist is your best option

Driving FBO + RB's for more then 50k km's with a DCT.
Meth or e85 mixes...
The clutches will wear faster, further no issues besides regular maintenance, propper warming up the oil makes a big difference.
Also keep the box in sport mode when beating it up, less slippage.

I am about to install an aquamist kit and I am fbo. Hopefully I wont have issues

Allen@MOTIV · 04-17-2014, 06:51 PM

The DCT trans does seem to hold up pretty well, even with E85 or Ethanol. Of course, with a ton of power you always increases the wear on components. Fortunately, just because you are running methanol it doesn't mean that you have to push the power to the limit. Through tuning you can always keep the torque down low and emphasize the power higher in the rev range which makes life easier on the trans.

how soon? I'd really like hear about your initial results after, are you ptf tuned as well?

how much whp do you think meth will add allen?
im currently fbo with ptf tune, around 390whp 410wtq peaking around 16.5psi.

great to hear, you must have 500+wtq as well... must be a blast to drive!!

30-40whp is possible. 420whp/420wtq would make for a very fun car

No, no meth, I dont believe in meth....lol, too much E85 around where I live

lucky bastard...I want some e85 or even 93 octane here.

I have the PTF E50 map, and that puts out a lot of torque. My DCT had no issues with it at all.

The key is when you want to go WOT make sure to have Sport enabled. Also, after enabling Sport down shift before going WOT. Stay away from D-Mode or S-Mode for WOT
