Question about Si trim
So got everything installed, made my butt *** ugly power pipe lol. i have a 3.33 pullie on my Si trim v1 so i had a few questions. How quickly are people building boost with stock hci? I ask because ive been flogging it a bit in the lower rpm, and at about 4-4500 i make 6psi WOT, so since its not tuned yet (before you flame me for railing an untuned car, i had it tuned on a dyno with the intent of it making 10psi but turned out my s trim was bad so the tune stayed in the car, but i upgraded the sc. thats why im only flogging low rpm not high yet. my af is safe at 11.5) Back to question at hand, is boost a linear thing? like if i started building boost at 3500, and make 6 psi at 4500 would it be accurate to assume 12psi at 5500? im just trying to get an idea of what ill make, cuz its killing me waiting for this dyno time to roll around. Plus i kinda thought the power pipe and s trim woul make a 3.33 pullie have at least 12psi, and i just dont feel like it would get there with the little tooling around that ive had... Plus im hoping that it pulls way harder above 5k because at 4500 just feels like its ok fast, not real fast. i think im just being deprived of my need for speed right now with this short shift stuff. If anyone can give me insight thatd be great.
