Lookin at compreesor maps, you need 450cfm for ~300 hp or 0.21 M/s . The K04 025 map doesnt show that flow on its map. It seems to go up to 0.18 M/s which is around 255hp.
Yes its under 300 bhp,even with a hybrid k04 over 300 does not seem possible when using the standard k04 manifold,i believe it is more restrictive than the STD k03 version!!! So to break through the 300 barrier,its a hybrid turbo + high flow manifold & 550cc injectors for starters.
Apparently it can be done with a manifold and a k04 non hybrid on an AGU and Saab Redtops. Waiting to see the plot.
Thats interesting,i think 300 ft-lb can be broken but i'm not so sure on the bhp with the redtops,one reason is here; http://www.clubgti.com/forum/showthread.php?t=246521&page=2 285 ish bhp using redtops @ 4 bar on a free breathing engine looking at the stats. I just wonder what BHP redtops are capable of at 3 bar (350cc) or 4 bar, is it 300 BHP? I don't know the answer tbh.
The car in question as far as I'm aware didn't have red injectors but still made 304 BHP Another car tuned by the same place (Bam) engine made 283 BHP with standard manifold and turbo
you say discussed, but feck me, there's some childish BS being spat at each other in that thread.. and a lot of unfounded BS.... total shyte in some respects you got to luv forums and the "experts" it brings out... feck me!
unaided.. with higher flowing supporting mods.. typical max aiflow I see is 200-210g/s mass airflow with enhanced inlets, and other mods, the highest figure I've logged is ~230g/s from stock k04 turbo all std exhaust manifold... k04 hybrid >260g/s seen.
i ran 298bhp last weekend but ive sem manifold fitted, was going to try bills intake if i can squeeze in the rallye with abs and re dyno. another time i made 289bhp and 302lbft same new dastek dyno both times, nothing changed on car between these dyno pulls.
Good thread Brad, I was also looking into this. It would be interesting to see your current charts for your map. I will post the same to see the comparison when I get mine mapped on the 26th by Jim @ JKM. I can also get the mapped tweaked when the XS manifold goes on. On my current setup I am looking at 260bhp + 300 ft lb which is standard turbo/manifold with Badger 5 + JR filer and FMIC but on Emerald as you know.
Well found out I was wishful thinking I made 254 bhp at 1.35bar and 1.2bar to redline, 275ft.lb of healthy torque.
N75 E and contolled by the ECU that's it. I am happy with it. Going to investigate reducing high air temps on high boost and egt temperatures next, then make some changes and tweak the map to see the outcome.
The TT inlet does tend to heat soak from the engine bay too. Which in turn radiates onto the temp sender. I managed to slow the heat soak with a gasket. I was getting lean fuel on a hot startup due to this. What temps are you seeing? Is your IC getting enough airflow?
