Put a smaller pulley on.
Was that other boost achieved on the stock engine?
Yes on stock engine.
Smaller pulley will over spin the rotor beyond factory specs, and I had the same size pulley previously.
Just might be inlet restrictions. But I'm really happy with the power, feels so good even though it's max boost is not what I hoped for.
I'll just live with it. Tired of worrying about it.
Your last explanation sounds right. Move volume = more power. PSI doesn't really mean much. Lots of variables that can change boost.
I want to buy the intake system with filter compartment that comes with the URD mk3 kit. Anyone willing to sell his? I know some people, @shane881510 , who have replaced it with an open pod filter.
Anyone wanting to sell his lemme know.
Still quite small filter, and that snorkel(?) hose might cause a lot of restriction for air flowing too.
I agree, I'm looking to find a way to fit a larger filter. However, it is much larger than the old one, and I was able to make 10.7 PSI from the old one, with the same flexible duct and a smaller supercharger. So can't be the reason.
Have you tried running with just a large cone filter, for testing purposes? To see if any differences were had? Or briefly with no filter?
No I didn't. Not good for the engine, air will be too hot even before compression, will result in bad knock at WOT. I don't want to take the risk. It will be sucking in hot air leaving the radiator, further heated by the headers.
I tried it without the supercharger and was knocking bad, imagine how it would do with a supercharger.
Then maybe you should talk to whoever you're buying those intakes from, to make a larger one.
I'm trying to get my hands on a URD intake. That would be awesome.
