For us HP and lb/ft people: https://www.convertunits.com/from/hp/to/ps 624PS = 615HP....Very close, I always thought the PS numbers were way higher that HP. https://www.convertunits.com/from/lb-ft/to/N-m 821NM = 605lb/ft...So maybe this was what I was thinking. Is there a big difference in lag when moving to the 2+ or HF's as compared to the stock turbos? BTW, I live in Germany, where is Peter of Pure Turbos Europe located?

ed i think thats showing the power increase between the previous tune and now the Pures.
i.e it was stage 2 550 and now 740. i dont think 1 is crank and other is wheel

Im not sure buddy... as they seem to be following the same path but obviously at a different level ..... if there had been a turbo change I wouldn’t expect the curve to look exactly the same but just at a higher level.... or maybe wrong?

Yeah I know this but just trying to understand why the dynos state engine power on the graphs but everyone quotes wheel power?
Even at a 10% transmission loss , which is pretty low, the car with 740 would have 810 hp at the fly/crank.... so just short of double the OEM cars power for those mods from a standard engined car........ something just isn’t right there imo.... would love this clarified |

I have always understood that you have roughly a 15% drivetrain loss through RWD. With that being said, you're looking at about 870HP. I don't understand what you think isn't right....? Many cars can over double the factory HP on a stock engine with forced induction and fueling. Google is your friend, man. Might want to search to find any further answers you're looking for as we are taking away from the purpose of this thread. Last edited by Schultz28; 02-11-2020 at 05:23 PM.. |

are you guys running a port injection fuel system to hit these mid 600 numbers on pump gas? or just the stock fuel system ?
I'm aiming to be at mid 700s with upgraded turbos on pump gas. is that possible with the port injection and upgraded turbos? |

Pretty sure you'll need meth injection to get there.
