not too shabby for a p20 exhaust housing..

for reference, an old datalog can be found here: http://forums.nasioc.com/forums/show...8&postcount=34

interestingly, the boost comes in at EXACTLY the same rate!

1 bar @ 3075
20psi @ 3280
3.0mafv @ 2784/5.1psi
3.5mafv @ 3027/12.7psi

i guess a bigger tmic doesn't hurt spool so much after all. there is a little advantage to the old run in terms of mafv, but it was a month later in the year and colder. besides back then i only ran 20psi... i have a feeling i'm gonna run out of fuel this winter, at least until i turn up the fire under my walbro's ass.

for even more reference, an old td04 record-breaking spool log: http://forums.nasioc.com/forums/show...2&postcount=18

1 bar @ 2289 (800rpms before the vf23)
3.0mafv @ 2116/10.6psi (600rpms before the vf23)

i must point out it was a LOT colder that day, though.

ken

ps if anyone else has some datalogs of spoolup map/rpm/maf for various turbos, post 'em up.
