So has anyone gone north of 400whp with this kit yet?

That same header would *lose* power on a NA car because the exhaust velocity will be too low due to the increased volume of the header. http://counterspacegarage.com/ace-anaconda-48-gt86.html |

Might sell off my turbo stuff and switch if I can get around 450whp with a twin screw and I really like this kit.

The limit to power is the amount of air the blower can flow not the max psi.

Here's a chart of a 3rd gear WOT datalog on my system with the stock 95mm pulley.
http://www.datazap.me/u/armstrom/3rd...a=2-6-8&solo=8 Yes, it comes into positive pressure pretty much as soon as the bypass valve closes. But at 2700 RPM I'm only making .2 bar of boost (~3 PSI) Boost continues to climb throughout the entire pull until it hits a peak of .6 bar (8.9 PSI) at 7075 RPM... I ran out of road so I didn't rev to the limit.... PD blowers come on boost more quickly than centrifugal blowers, yes... but that doesn't mean boost doesn't build over the RPM range. A well sized turbo may be able to hit my peak of 9PSI before 3000RPM and then hold it throughout the entire rev range. That would yield more area under the curve and a faster accelerating car. Peak numbers can be misleading. Don't get me wrong, I really enjoy my Harrop kit but the power delivery is very different than a turbo car. Throttle response is pretty much instant but the power builds linearly rather than hitting hard like a turbo would. -Matt |

I'm not sure how you'd get 450whp. I don't know of anyone in the TVS1320 community who's dropped the compression on an engine build. I remember cosworth's Matt saying he thought a slight drop to 11:1 would be optimal for a twin screw set up. Maybe that's the way forward. One thing to consider if you swap is that you'll not make much power on 91. |

Since superchargers typically do not have any method of closed-loop boost control like turbos do that means even at a steady state (load the engine so that a given throttle input does not result in an increase in RPM) the boost will still build over time even without an increase in RPM until it hits equilibrium due to a drop in pumping efficiency as the pressure ratio increases. -Matt |

If you have lots of E85 available locally then by all means, stick with the stock CR and get big power. But for me, a better compromise is to have a lower CR and still make mid 300s at the wheels on pump gas. I only know of one E85 station anywhere near me and that would involve a 45min round trip just to fill up... not convenient. Of course, I've never seen any dyno plots of this configuration so it's pure speculation on my part for now -Matt |

Yeah im looking for more low end torque. A pd blower will out pull most turbos until about 4500rpm which is where most people drive daily. Don't get me wrong the rush of 500+whp is fun but around town it's a dogs breakfast. I know boost builds over rpm but it builds it miles quicker than any other form of boost. I just don't wanna sell all my shit then be limited to like 350hp.
