Thanks for the responses guys, still wanting to hear what I need to do to get more boost, I guess it's time to start playing with the pump tuning some soon. Thanks again.

 

Boost is related to fuel input. More fuel = more boost.

 

pods are the industrial injector and they really dont flow that much more.I think theyre only a 40hp injector.

 

The mechanic that installed the injectors bench tested them compared to my stockers and he said they have a spray pattern about 10 times bigger than the stock ones. They seem to throw out plenty of fuel so far, I guess I'll get to cranking the fuel screw and see what kind of boost I can make and still keep the EGTs reasonable for towing. About time to load the trailer up behind it and see what happens.

 

I get right at 20psi w/ a h1c turbo that is past needing to be rebuilt, and stock injectors, a stock fuel pump, and a stock injector pump that could be turned up more, but when the engine has been running a couple of hours @ mid rpm's and the fuel is hot, I'm ending up with a black haze @ full throttle. My 91.5 comes with a 21ccm turbo housing but if one puts the 14 or 16 on I hear the turbo will spool up faster (which I believe without seeing the results yet). Not sure how much full throttle boost you will get w/ "better" injectors though.

Be careful about turning the injector pump up if you have a 5 speed manual. The automatics were the only tranny's holding stock 1st gens w/ the injector pump turned up.

 

I did the 14cm housing this weekend, and it is amazing how fast my turbo spools up. No more lag for this kid.

 

i'm making 27-29 psi now with my new s300, and love it egts are way cooler almost 350 degree drop, but here soon im planning on getting an airdog 165 with the adj regulator.

If i get this will it make my boost go up since there will be more fuel pressure and fuel.
