you all forget we are talking about 2.0 CR engine, 303hp is the best result so far until proven otherwise, and nobody came even close to this result
trying to push 320 and 2260vk is more than enough for that, do you all agree?
so in reality i dont need a better turbo, right?

i dont know if my fuel setup will be enough, and i'm talking about injectors here
i am replacing the original with something else

They are also talking about 2l CR
This 303hp you talk about - do you have any more details? EGT's, smoke any proven 1/4 times?

you have different dyno launches on the other topic, you can see power increase on the same dyno in different setups, and the results are well in line with other tuners from Italy and NL
last setup is 297hp but better torque curve
the car is a DD passat SW not a race car, very low smoke, dont know iq and egt, cant monitor them in torque

Tbh the cars which I know run 2.4 bar and pambda 1.1 at 4k rpm and theyre not doing anywhere near 300 hp. maybe the air is thinner over here lol..

what do you want me to say? maybe its down to how competent the tuner is
Eric was working for months on that car, i cant imagine anybody spending so much time on a particular model.
remember the more fuel flowing 2.0pd is good for 360-380hp , there are so many in italy putting out 380hp without wmi
want me to post dyno as well for you to be convinced?
just because you haven't got there "yet" doesnt mean its impossible.

when i tune mine i will also do a run with current setup revo2 and of course final run mapped

to have an idea of the accuracy of the dyno , 2 runs on stock map and tuned one for stock 180KW bmw engine

just FYI. I tuned these cars and no matter what skill, or lack there-of, the tuner has. the engine only flows y amount of air for x amount of boost (considering equal size turbo/emp). no tuner can change that without hardware changes

Goes to show the CR head is not flowing so well actual worse than BKD it seems.
With 2.3 bar i got 1.1 lambda with just under 900deg - on track egt's are approx 930.

IIRC you said these cars with 300hp are running stock rail pressure, would be interesting to know egt's.

I agree :-)

Airflow is crap.

incredible what you find if you search for it, he even has the DATA to back it up

TDIsyncro has the flow data of stock CR170 injectors , more than enough for 300hp, told you so!

hmm maybe the cars I tuned with 2260vk of which 1 with CP3 must have had a bad head casting then? putting a head on a flow bench alone also doesn't mean much. there still needs to be a camshaft to open the valves.

What counts is: you have x boost and y airflow. this airflow is hard to understand wrongly because as soon as you hit lambda (measured) of 1.1 you are 'out of air'. its also no rocket science to calculate power even without going on a dyno if you have extrapolated the duration map properly and have a certain amount of logical understanding of specific fuel consumption/brake efficiency at certain engine conditions.
A (healthy) CP4 in all these cars definitely does not flow anywhere above 270hp. this is with no current on the metering unit and stock case pressure regulator at 4k rpm.

in your case it seems hard to understand that for a tuning company posting a dynosheet with pretty numbers is the best and cheapest way of marketing

Yes it's x amount of airflow lb/m that the head can flow at y pr.
With a 2260vk.

Go to Italy you can run 108mg on stock pump at 1750bar ..... must be oem cp3 on european cars. :-)
