well, pulled my intake manifold and tumble valve housing this weekend, the one tumble valve has been broken for some time now and i discovered it was near 90% closed all this time.... (that's some serious airflow restriction in 2 out of 4 of the intake pathways...one TGV motor drives two butterfly valves... and the car still seemed fast all this time)... anyways... i pulled the butterfly flaps and they are happily gone forever now.......
also... buttloads of electrical connectors and hoses to be pulled, what a PIA it was.... (and i haven't put it all back together yet, uhoh... waiting for gaskets and PERRIN silicone intake pipe)
to get to the VF22 point... i checked my VF30 and it has enough shaft play to allow the blade to just slightly catch the housing as I spin it with my bare hand....... in other words... its seen better days, and the worst part is, it's only got about 5k miles on it... that sucks....
but i'm going to upgrade the turbo soon, not sure what to get, figuring i'll get the VF22... what kind of WHP can i expect from it with a good tune... (stage 4 car with GTspec headers, no CATS, front mount PERRIN, UTEC used for engine mngmt) and what 1/4 time can be run with this turbo, assuming the drivetrain and clutch held up and a good driver was at the wheel... ?
Can a PE1818 or an SR30, maybe SR40 make more HP than the VF22 or be better turbo to get... I don't get it... the PE's are real expensive, the SR's are rich-person expensive, and the VF22 is $600 shipped from Gruppe-S.... i don't see the point in getting those more expensive turbos when a VF22 can make the same or more powre.... anyone care to fill me in???
thanks.
