I wonder if you'll notice the increase from 190HP stock, to 230HP..
I was hoping for more like ~250HP, and a quick spool-up, without going through the cost of another turbo.
For that, I'll probably need to run the system at 28PSI.
When stock horsepower is mentioned people are referring to HP at the flywheel.
When tuned horsepower is talked about they are talking about at the Wheels.
Stock horsepower at the wheels is about 15% less than what you see advertised.
Stock horsepower at the wheels is closer to 170 HP +/- 5 hp.
so put simply you will notice the difference between stock and tuned.
Not sure anyone has achieved 250 WHP with a stock turbo.
I am running 28 psi on 93 oct and I am not close to 250 whp and I don't think e30 would get me close either.
Holy crap, 28 psi on stock turbo without ethanol? WITH ethanol/e30 I'm tuned for 26.5 psi, on 93 you are just creating tons of heat past 25 psi... Did Stratified custom tune you that high? I feel they run a bit too high of boost for comfort... But yes, 220-230 whp is what you see with e30 tunes, if OP is serious about 250 whp then it's definitely a hybrid turbo to get there.
