I did the dual air feed mod to an unmolested Dynatwist on the weekend but only managed 192 g/sec. Hopefully better results to come when i modify the housing. i need to beat 218g/sec to maintain the same performance as my jetex open cone. It was warm though.
Disapointing results Carl
I don't know how we managed between 210-220 with unmolested housings. All seem to be different but like you say... Temps make a big difference.
your using the larger maf housing though aren't you? so how would you convert that to if you were using the 3" maf?
Hadn't you and Nick drilled holes in the end of yours though Aaron??
i cant remember what figures i ran before drilling those holes ED, i didnt label the logs well enough
I'm trying to keep a low profile in another persons ride thread so i'll only comment on mods relevant to Probees car too.your using the larger maf housing though aren't you? so how would you convert that to if you were using the 3" maf?

Thats interesting, why did you decides to change boost pipe set up.im now running solid (tubes) boost pipework, it seems very responsive now, im very impressed with it.
