Interesting...

I plotted swooshek's dyno onto a similar one that I had when the car was first tuned on a similar dyno.
allowing for the shift in the graphs (move the pencilled line about 3/4 of a square to the left) they look quite similar, although I am running about 1-1.5PSI more on average throughout the rev range.



My car still had a 2.25 inch exhaust at this time.
Interesting to compare this chart to the one on the first page as well, that one is about 10kw higher right through the rev range after re-tuning for the new 2.5inch exhaust.

different days, different dynos= 134kw max as compared to this 157kw

just to put your pic on here instead of the link, hope you don't mind-


BTW, 216hp is approximately 161kw

That's a bit low for a B18

I'm making 202HP ATW on only 8psi on my SiR 2 B16A 2.5inch exhaust

you took the words out of my mouth luke...

I wanted to say the same but didnt want to put the guy down. I was getting around 161kw on 8psi on a very rough tune.

im on 168kw atm with my 10psi tune which is very rough and is lacking a new pressure sensor. It was almost a "this will do for now" tune.

Might be his tune, A&F mix is all over the show

Most guys with boosted B18's are making about 170kw 7-8psi..

FF - my car seems to hold 10psi fine, need another map sensor?

Nah nah we were tuning it for 22-24psi and it was having issues couldnt figure it out and the only psi that wasnt making my ECU read randomly was 10psi or under so we chucked it at 10psi roughly enough for me to come back after ive figured out the issue. In the end i found that my stock map sensor only reads upto 10psi which i didnt know. Havent got another sensor yet and havent retuned it. So the 10psi tune i have atm was just rough and i got 168kw thats all i was trying to say.

You want to give me that map sensor you got in your toolbox

Stock will handle about 12ish

Na give me your MAP Hao

[FastFwd]

mine got to 11psi is think and even on 11 is was fairly safe but not 100%.

Dont know if different ECU's react differently with the stock map sensor or not.

[Limbo]

nah you need to upgrade the map sensor when going over 10PSI otherwise your readings go crappy, doesn't matter what ECU

FF - nah i'm holding on the the 3bar sensor, its a Bosche so should be decent in case i wanna go higher. Been told they are hard to come by.
