Shane's 525whp Twin Scroll HTA3582
Congrats Shane This looks to be a kick-*** combination. I'm definately impressed by the early spool on a 2.0
I'm now thinking about moving up from my fpblack and going to a twin scroll fp3586 on my 2.4.

Yeah, the difference in the exhaust back pressure can have far reaching effects. You can run a cam with more overlap, extending the RPM range at a given boost level. Or up the boost until reversion becomes an issue again. Higher compression ratios like it too.

The 86 was running the same boost but the twin scroll allowed me to do a few things I couldnt on my 86 car in that graph. I was down to 9-10* of timing to keep it from knocking where the TS car could run 11-12* at the same boost level. This is most of the power difference as the mods were otherwise pretty close.
Next it seems that if you start a pull with more boost and/or more timing early on it will carry through the pull and just make more power. I think a 3586 in a TS will spool the same and not have any restrictions until higher boost levels. I would be excited to try a 3786 at some point to get the larger twin scroll housing and a larger turbine.

I must say that the anti-surge on this turbo is one of it's best features!
I never see people on here talk about it, but my old 8 turbo would surge all the time when going up hills (when barley pressing the gas). I can't even get this turbo to surge on purpose! Just plain AWESOME
