If you knew anything about how a turbo worked then you would just know that its not possible to produce 400whp on the SR and still have the turbo spooling at 2000rpm If you researched it breifly before posting and found threads on here where people with GT2871s dyno in around 350whp but arent seeing turbo spool till the 3500-4000rpm range then you’d realize there is no way in hell you will make that kind of power and still spool up at a low RPM. BUT instead, you decided to post vs researching it on your own and you got flammed… lesson learned I hope. --- _[View the full topic](https://forums.speedlife.net/t/possible-to-build-a-400whp-sr-that-spools-by-2000-3000rpm/107276)._
