Tiguan IS38 and Big turbo upgrades

[Beedub]

That’s an amazing list. Thanks mate.

I’m leaning towards 3 for no particular reason (there’s too many, maybe haha).

1. Burger (BMS) - currently $379us plus shipping.
2. CTS - I have their DP already but $799 + shipping but they do have sales.
3. Integrated Engineering - fancy but a bit expensive.

Anyone of those really standout for an IS38 car?

FYI I bought the Wagner kit from Performance Brands Group for $1528 delivered.
Make sure you get all the fittings with whatever you choose.

I put up graphs of my stock, stage 1, stage 2 and stage 3 on the same dyno..

I asked asked some of the APR tuned Tigs in Vic to come and run their car on the same dyno as I did to see if there are any differences.. I dont think there will be much overall power differences, maybe slightly different curves.

I just had a search for those graphs and can't find them, can you post a link please. Can someone tell me what a stage one, two & three tune is please, I thought these terms went out with carbies, heads, cams and extractors.

There's variations, however generally:

Stage 1 - software only
Stage 2 - DP + software
Stage 3 - big turbo + stock engine
Stage 4 - big turbo + built engine

Some say that IS38 swap is stage 2.5 as it's still a "stock" turbo. Anything bigger than a IS38 (hybrid, etc) is a "proper" stage 3. Some people get a bit caught up on it but it's mainly so people know what level of mods your ar has.

Just a quick one I noticed the dyno pull with 238kws was done in June at 13 degrees. Mine was done during the heavy smoke days at 28degrees. Oxygen and heat would not have helped.

Certainly not going to make up the difference but would not be surprised if it got to 200kws. Ps I think that was a Hybrid anyway? Lastly what’s the torque figure?

Yes both smoke and temperature will effect your result as with higher ambient temps you'll have less dense air and potentially less %oxygen with the smoke.

It's really hard (almost impossible) to compare results on different dynos. I have all but given up as there's way too many variables including which gear the car is run in and how the car is strapped down. That's beside the ambient temps/atmospheric conditions of the day.

Yes my 239.8kw is with a IS38 hybrid turbo (TTE475) so you won't see that number just with a stock IS38. If

Does anyone believe the 70kw claimed increase by Bluefin? That is only just south of a turbo change so why go to all the trouble of a turbo swap if Blufin's claim is true.

I can’t confirm the Bluefin claim. Some are not considering there is more power to be extracted from the EA888 LONG BEFORE a turbo upgrade. It makes absolutely no sense to me doing a turbo upgrade before you have extracted every HP available first. It’s why most do it in stages, why go straight to a turbo swap when you haven’t extracted the vital HP that will only serve as more HP once you get to the turbo swap?

I’m definitely conservative when it comes to power and motor claims as you have probably seen in this thread alone.

I can confirm though that I trialed the bluefin and was blown away by the difference of the stage 1 tune.

No launch control, just floor it off the lights, and traction light would come on. The car felt crazy different.

If I was to do it all again, I’d probably just get stage 2 with bluefin. In other words, just do an exhaust and air filter and maybe a cooler and get the bluefin without doing the turbo and custom tune it was that good.

I’ll see after the break if I feel the same as I’m car is getting another look at.

Only reason I did it is because of the cost of Labour of swapping the DP might as well do the turbo as well.

Understand that Rexman but what I don’t understand is why you didn’t keep the tune and then get the DP, that alone would have been impressive! I’m not having a crack at you bud but I can’t understand why you went this way other than for the sake of saving labour? No one is making over exaggerated claims about their upgraded power, it’s what they are seeing, just seems to me like your doing things in reverse. That said I don’t know what else you have done to your car. Have you done any pipe work upgrades, turbo muffler delete and turbo elbow etc? Main intake and stage 2 intake pipes? These four components alone are only going to small but positive changes until you upgrade the turbo, which obviously you have done already. It all combines to reach the figures the guys who have done stage 1, 2 and 3 are seeing.
