Do I understand right you are running PNP LM6XX on stock engine(stock piston, rods, valves...) and running around 600HP and 650Nm?
Are you planning running 750Nm also on stock engine? Im not sure if internals can handle that torque
Its not HP which kill engines but torque kill them...
How is PNP LM6XX driveable as daly car? Did you have TTE525 or TTE535 on your car? In future I will also look for turbo upgrade for my Cupra, but because 95% of time I drive slow I would like to use turbo which spool similar to OEM but produce around 500HP and safe torque for stock engine&DSG&4DRIVE...
Hi Dejan, thanks for your professional answer. You are fully right. Torque kills an engine.
The CJX (EA888 Gen.2 2.0 TSI in Golf MK7, etc.) can be killed by Torque more than 620 NM.
I drove with PNP LM500 with 502HP and 607 NM for 40.000km and when we increased Torque to 625 NM one piston immediately!!! crashed after some km full throttle at 300 km/h on German highway. So I got forged pistons and IE rods installed and the car runs great again.
I know the TTH480, TTE525, 470 and newer 535 very well. MTR Performance seems to be the only guy who can adjust them properly and tune them powerfully because he is an expert. The TTH/TTE and others normally seem to still keep and reuse the stock IHI bearing/basic unit which everyone knows is weak (turbine shaft crashes, etc.) already blowing on lots of normally tuned IS38 (See the whole internet forums worldwide of Golf MK7, Cupra MK3, Audi S3 8V/TTS,etc. SEE PICTURE 1). I have seen lots of charger blow on the dyno or at the second launch control action. This is really sad and expensive because you do not get your money back. Always because of the reused stock bearing which most of the turbo builder just keep and reuse because the turbo builders want to save money and increase profit. BUT: You cannot trust the stock IHI bearing/basic unit and turbo internals - So all LM chargers (also the smallest LM440) by Ladermanufaktur PNP Turbo have kicked the complete stock basic unit out and replace it fully by the TD05+ basic unit by Mitsubishi and developed it further (so the '+' in the name) and it has seemed indestructible for 7 years in extreme worldwide racing. Some younger drivers like to save about 400 bucks and buy hybrids with stock basic units where just the wheels are bigger and/or the basic unit is a Chinese copy and their whole money is gone after a few months/weeks. Young driver should INVEST in Quality guiding them for decades - Older drivers have learned this very useful lesson
LM chargers are famouslighter, for their extremely early turbo spooling (LM440 and LM500). Even the LM6XX starts very early. It starts pushing from 1500rpm and there is no real kick but you feel that at 3300 there is even more boost gradual. So all LM chargers do not know a turbo lag or turbo hole because they have OptiRateTechnology where both wheels are newly designed and therefore much more efficient, bigger and HiFlow playing together very well because LM has the technical equipment to calculate characteristic maps of IS20/IS38 housings, wheels sizes, mass airflow, etc. to make daily driving so wonderful. I had lots of TDI diesel engines in the past and licked early boost and that is why I personally prefer LM chargers - they are so much the same. And if one LM chargers blows, whch has not happened since the release in 2016, you will get a new one for free. But you will not manage to kill it because of the above mentioned technical advantages. That is why I have sticked to LM chargers and will possibly do for the next one or two years because their charges are technically advanced and their development is about 1,5 - 2 years ahead as far as I can observe and assess it from my daily driving in my Cupra Year 2014 and racing on German Autobahn A2 and A1.
Just my personal view on the IS38 / IS20 matter:
When driving fully stable and reliable
- 430 HP - Install the LM440 IS20 - This is my FAVOURITE Charger - It goes like crazy.
- 460 HP: Install the LM440 IS38 - Spool is 300 rpm later because housing is bigger but gives +30HP therefore.
- 500 HP: Instal, the LM500 IS38 - which is the best running product so far: Extremely early turbo starting + Broad torque (2700 - 7200 rpm constant increase - so powerful - see all dynograms)
- 550-620 HP: the LM6XX - Check how incredibly early boost starts in the videos given above
All in all, lots of drivers have the LM500 on stock engine with 500 HP - This chargers wants to make more power easily - But ask your personal tuner first regarding required hardware. When driving 95% normally slow like you and me, this is a peprfectly comfortable choice. Expensive 911 Porsche have no chance competing anymore and after beating them you will see them selling their Porsches at Ebay's the next day.

VIDEO of IS38 attached for technical advice:
This is an original IS38 (New revision produced on 18 th April 2018 - see stamp) Stock basic unit but tuned after 2000km. It blew on the dyno at 1.6 bar boost pressure because of weak IHI basic unit. Lots of older and newer! blow when tuned. Question: How can you use the poor stock basic unit to make a big 450+ HP hybrid of it expecting it to be stable ???
Invest in stability, endurance and reliabilty as a life-time principle. Consequently I have installed the PNP LM Upgradecharger with TD05+ basic unit + HiFlow compressor wheel for broad performance + highly efficient exhaust wheel (OptiRateTechnology) for very early turbo spooling.
This is a new ORIGINAL IS20 (smaller brother of IS38 - lateral cut). Assess the stock bearing/basicunit. It is good for stock software but can cause severe problems when tuned.
