Pros and Cons of new 1.4 tsi Jetta

[neexis]

Looks like Bunny just plan his next mod there

forge diverter valve
bigger IC
remap
apr intake

So can we safely say by now that we can expect at least 200bhp or 170whp for the least with the above mods? Would this mean GTi type acceleration (ie. mid 6s range to 100kmph)?

Ok so the diverter valve opens when it gets a signal from the ecu or just on its own once the pressure goes too high?

with these mods we talking around 270hp 280tq...that's my goal

ECU controls it as this is what the solenoid is for....and agent we remap this is how we are able to increase boost...

Can the present pistons be able to handle the proposed increase in power?

What about the stock injectors?

Oh Great VW Celestial Being.

The pistons in these engines are split forged and can withstand just around 350 lb ft torque from what I have seen....clutches handle up to 300tq from factory based on the dsg tune I did to my car...injectors around same benchmark also.....only when you cross that will parts need to be upgraded....

[EcoTune Trinidad]

Forgot to mention stage one maps bring the 0-60mph to low 6 sec bracket in a polo gti..so our Jetta should be around 6.5 sec software only..

I have seen slips online for 300hp polo gti doing 5.5sec

power at the crank estimated based on software and mods...these dsg suffer the least drivetrains power loss due to absence of torque converter and tranny oil

it does seem to hold boost longer

VW seems to have revised the part again. Revision E is the latest now and it sports a different design. Has a piston now similar to the Forge.

03c-145-710D on the left. 03c-145-710E on the right.


New Jettas may be getting the E already as it's been out since September 2012. I wonder how the two compare.

[drchaos]

Hmmm I'm probably on D, my engine has a july 2012 manufacture date.

You guys see the face-lifted jetta? Looks very much more passatish

One on the right looks like it can hold up to extreme temps under constant thrashing and quite possibly can hold more boost - which means some of us may not need to upgrade after remap; can only be certain if we had info on the spring tension behind the piston...care to dissect both?

[Allergic2BunnyEars]

Oh that's a pic I found online. Have no access to E.

dropped in vehicle today to have some changes made, including changing that worn clutch

this is what a worn clutch looks like
video starts in 3rd gear
slippage occurs in 4th gear (K2 clutch is responsible for R,2,4,&6) just between 3k and 4k rpm.
you'll notice the rpm jumps
gear 1,3,5,7 pull without problem.

[Allergic2BunnyEars]

Props for the vid. Didn't expect it to look like that. What did you use to record the video?

[syncrod]

galaxy s3, video was shaky so i used a free app call VideoPad to try and stabilize the video, so it does look abit funky

[drchaos]

how old and what mileage if u dont mind me askin?

[syncrod]

34700miles, been like that since about 16000miles
car is about 5 years old

[drchaos]

Jeez now my mechatronic anxiety is over I have to deal with clutch wear anxiety ....

[Allergic2BunnyEars]

Clutch wear is the last thing you should worry about.

[syncrod]

Jeez now my mechatronic anxiety is over I have to deal with clutch wear anxiety ....

this car was basically babied for 4 years. alot of light footed drive for short periods. in D mode. so unless u chinksing on the gas doubt you have to worry about it.
it was only discovered because my foot heavier. (not as heavy as some in this thread)

[EcoTune Trinidad]

Not sure why drchaos worrying about clutches for tho... Especially since I announced newer model clutches can withstand 300lb tq from factory... This means the clutch material has been updated...

You sure is me worrying bout clutches?

[EcoTune Trinidad]

What you talking about bro
Stop editing my post

[neexis]

Hahahaha.. My posts are tuned by EcoTune.. they spool up faster than yours

[EcoTune Trinidad]

ROFL...good one nexis....take win...lol

[jhonnieblue]

Quick ques guys.. has anyone been using ron91 in the passat version 1.8t regularly?
any feedback to how it performs or long term effect?

[Allergic2BunnyEars]

Think the lowest we get here is RON 92 in super. Do you have the manual for your model Passat? If so check it and don't go below what it recommends.
