Thank you , but No top honors here :lol: , This was not planned , I was just using the 2.8 for mocking-up purposes for the
future 2.5 motor , it seem like the farther along I got the more slippery it became , next thing I know I'm thinking (dangerous)
let's try it just temporary ,then will put it back to N.A. , (Yeah right ) that was it, I got bitten , it really woke this motor up ,
I Do Not have expensive heads 48 x 38 with self porting ,Jorge at EMW (www.europeanmotorworks.com/vw/type-4-engine-parts.html )
did the twinplug modication , being non-welded they don't flow very good on the higher rpm range was my thinking, so lets try a
little boost just to see what happens , I was Hooked :shock: , so this is boosting I don't think I can go back :lol: , I'm hoping I
finish the 2.5 soon , so I can put the other spring back in the waste gate :roll: :lol:

Hey Wally , WI comes in as soon as boost comes in , I have it programmed to start spraying at about 2 lbs. and it progresses
from there , more boost more spray it's a progressive programmable system , I use their boost juice, for me the mix will be
more acurite then me trying mix it,
my best guesstimate maybe 220 NA @ the flywheel , the pressure plate is Kennedy custom 2-1/2 stage , disk is custom from
clutchnet , which seems I can't replace , as far as the gear box they say 300 or so HP , they attach V8's to them , they have
a weak first gear , and they can Not be speed shifted :mrgreen: , I have a taller 5th gear & a little shorter 3rd gear installed

Good call to let spray come in that qickly! It will save the set-up if you keep boost at the curent 6-7 psi ;-)

I am surprised you have not slipped the clutch yet!
