TurboXS Dump Pipe and Recode Tuning for Golf R

[PTW]

Mark,

With the increase in boost pressure after the tune, im wondering if the stock DV is remaining closed on full boost and WOT...if not, i wonder if putting a stiffer spring inside the stock unit is possible ie where can i find a spring that will fit?

Any idea's?

You're talking blow off valve I gather? What makes you think it's not opening, what are the symptoms?

[KRA21E]

Blow off Valve (Vents to atmosphere), Diverter Valve (Vents back to intake) are same thing...What i mean is, is the vlave remaining closed on full boost and full throttle and not allowing boost to leak...Just want to make sure that the boost level is not also forcing open the DV.

btw, your a spastic re your comment in the other thread! lol

you've got the later model one, it will be fine. If your still a bit concerned I will sell you my last Kuhneutson Valve for $300 cash

BOV's can & do return as well.

You haven't answered why you think this is happening? Have you noticed a sudden change? What's happened to make you question it?

[KRA21E]

Nothing happened, I was just thinking if w are changing the wastegate to make it more reliable, should we beefing up the dv aswell...it very easy to change the spring in the dv, trust me, once you un bolt it, it all just comes apart.

No worries, Mark has replied anyway but I thought you were only going up in boost by ~ 2psi which is bugger all. Maybe it's more .....................

I don't even know where it is, very easy on a wrx on the top, but if it's in a more difficult spot then it was a good point to think about while you were doing the actuator - now it makes sense.

Had the car custom tuned today by Mark at recode.

198kw atw with TXS downpipe and Autotech pump internals. There was more room for boost but he pulled it back until I get some other bits done.

It's mental to drive and exceeded expectations. I'm dying to see how much power these cars make with RS4 valve, actuator and FMIC upgrade as I can see huge room for improvement.

Mark can post up the dyno if he is happy to do so.

[parso_rex]

Oh you mean this thing



As usual 10Kph Ramp 4th gear - not that it makes any difference

Note the stock power. This has me stuffed. It has in stock form somehow benefited from the TXS Dump pipe much as my previous logging and dyno runs have shown not to be the case in the past. The difference is Glen has driven with the TXS/ insert pipe of your choice.... for over 2000kms and not 2 minutes after a remap, I expected the typical 155~160kW atw but no. I will investigate this in more detail when time permits. I have full logs to show the fueling, ignition timing and boost control with the totally stock arrangement, its fine - Apart from the Cat efficiency CEL that you'll see, that won't be an issue with the current file ...
We did a heap of runs and in hindsight I could have chosen better runs to show the gains but you get the picture


Goes hard

Gorans file for reference with the highest stock run

Hahaha, another happy customer!!! It's ferral ay?? One question for Mark though...why the big difference in torque between the two cars?

Parts are in transit! We will all be happy chappies soon!!

Mark,

That is different to the printout that i have...oh well, much of a muchness...We really need to work on rounding out that midrange from 3-5k and fix that dip above 6k!!

[parso_rex]

I have to choose the runs to print out and there are quite a lot most will be pretty similar. I usually do 8 runs per modified file, 6 minimum plus ones where I have screwed up due the kickdown switch, traction control, gear selected etc etc.... Doh !
Edit: that's actually a crap run to put up as the top end in yours is pretty flat sloping off ATM

[Fab_R]

Great results Mark.

Quick update with mine.

Had my TurboXS DP & Cat installed during the week, replacing the APR DP.

Will be logging this week and GIAC will be tweaking the file in light of the hardware changes made.

Had a before and after dyno run done on a mainline dyno, tune unchanged .

What were the results?

[Lucas_R]

Fab - no offence, but you have spend sooo much cash on this car and changing tunes and parts etc etc.. You are obviously not short of a dollar. Why dont you just strap a Garret GT30 / GT32 / GT35 or something onto a custom manifold, get Recode to tune it and get the thing pulling 250-260 kw at the wheels. Then you'll be doing a 12 flat down the quarter. There will be no need for more power.

GT35 should be alot more than a mere 260 ..................
