So... some assholes here in Germany royally pissed me off, shitting on my car because its not a "Cupra R" and only a Cupra... Needless to say I specifically bought my car for the AWD because I can't stand FWD cars. I would've bought a Cupra R if it was possible to get an AWD.
Funny enough there is a Cupra 4x4 2.8 v6 and in switzerland a 4x4 v6 supercharged from the factory (208ps and 265ps) but they are heavy dogs, and impossible to work on.
So now here I sit thinking **** them I will build an engine in my workshop to drop into my 4x4.
I will use a large port head for sure (AGU) or maybe the entire AGU engine.
BUT MY REAL QUESTION IS!!!!
My turbo of choice at 35psi can flow 45-50lbs/min of air and be sitting inside of the 74% efficiency island.
Is this enough to reach 550hp on E85?
I was told that 10lbs/min = 100hp im guessing thats on normal Petrol.
I understand that on e85 you can increase timing because of the cooling effects of the alcohol based fuel. But
First off Im trying to stay as a "smaller" big turbo to keep spool but still flow up top to my 7400rpm redline.
Assuming the AGU flows a 88% Volumetric Efficiency because of the larger port head
(85 for non vvt 4 valve per cylinder engines) (95 for vvt 4 valve per cylinder engines)
AGU is 5 valves per cylinder of course but non vvt (unless there is a conversion i can do???) but with a larger port head than others allowing better airflow.
I know that hp is just a measurement on a dyno and trust me im not building a dyno queen, my turbo or turbos of choice flow extremely well and have a broad and efficient compressor map/ power band. It would just be nice to have a dyno sheet with that 550 number as a goal to hit.
anyone guess my turbo or turbos of choice?
