Tiguan IS38 and Big turbo upgrades

[INASNT]

The mods are done.
I'm a little confused on the final figure when I look at what others have achieved, but nevertheless I'm stoked with how the car has turned out.
The ride height is spot on too, and while firmer it isn't rough. It's perfect.

It turns out when I took the car back the tune had been dialed back to 212awkw. The tuner had tried to explain to me he was reaching for 240+ but kept getting engine knock. I guess in all the excitement I misheard what he was explaining to me and thought it was running at just under 240 with more to come.

Everything checks out, the only way to increase it would be to up the octane I was told, but I'm not going E85. BP98 can be expensive enough as is.

Maybe it's the addition of the oil cooler, maybe it's the oil catch can?

I also suspect their dyno isn't very forgiving. When my R36 had a stage 1 it read close to 20awkw less than some others were getting.

You running IS38?

Might need to look at water/meth injection kit as next mod

Thanks davman.

And sorry mate, but at least you got a good price.

Beedub, your Wolfy looks awesome man - the more I look, the more I like the springs - it is perfect height now. I am hoping that it handles a whole lot better than stock - because stock handling is not the best for the beast you have now created. Handling is good though for the all rounder that it needs to be considering its target market, considering its a SUV, and considering its tow rating.

Unfortunately I ended up having to buy my springs from Eibach direct in Sydney - however they do a pretty good discount for VW Watercooled members, and considering I can claim the GST back, it wasnt a whole lot more than Tunershop in the end.

The KW you have will keep blowing your mind, you are not going to miss anything.

Might need to look at water / meth injection kit to get more out of the turbo

That's still a pretty decent increase - particularly given that the dyno looks like it reads pretty low. It's all relative I know when I ran mine on the dyno I was initially a little disappointed, however when I compared to all the other results that ran on the same dyno it was right up there.

I've run my car on a couple of dynos and there's been some quite inconsistent results in terms of how the dyno has been run and what gear the car was run in which makes a massive difference to the number on your dyno sheet. At the end of the day I was left scratching my head and pretty much gave up on getting a reasonable number that I could compare with

It looks like your dyno was run in 4th gear if you look at the speed/rpm which is similar to this run with mine. Max on this run was ~213kwaw which is pretty much in line with what your car is putting out (ignore the bit at the top end as it clearly upshifted).

Thanks tigger.

At the end of the day it's the curve that needs to be looked at, not the final figure.

E85 is cheaper than Pump98 eg; Yagoona United E85 = 139.9 Pump98 = 178.9.

Yes area under the curve is what it's about.

Hi mate, I’m really looking forward to your build. You’ve been a huge advocate for the community and it’s awesome to see that you’ve landed on the IS38 upgrade path. I’ll add a placeholder on the front page for you. All the best with your build, you must be pretty excited...

Thanks mate....

Was Initially going to go with a Littoc 550hp upgrade but changed my mind, will save the extra money the turbo and associated hardware would cost for my 'weekend' car fund.

Update...

Put the IS38 on Tuesday, noticed a few marks on the compressor wheel and slight comp to housing rub before putting it on that I did not notice when it got delivered, we thought the rub was because there was no oil in the turbo. I was pondering if I should install it, the IS20 was already out so decided to install it and see how it went.

Once installed oil run through it and car idling or reeving could not hear any rubbing so thought all good.

First baseline dyno run at 23psi car made 225kw@4 wheels beautiful power curve, then bang!!! and the car stalled!! Restarted the car and huge rattle from the turbo, removed the turbo and exhaust wheel was hanging loose... Luckily it happened on the dyno and not when I was driving the car otherwise might have dropped a bunch of oil down the exhaust and have to find the exhaust wheel in the cat, also could have put bits of metal through the intercooler and into the engine.



Had to put the stock turbo back on. Now in the process of claiming a refund through paypal for the turbo as clearly there was some damage to it before it was sold......

Hunt now begins for a replacement..Have found a few options so IS38 still on the cards.

Crap - sorry to hear INASNT - painful to say the least. However at least you saw the positives.
