Sounds like fun. Good thing you have new tires.

180 mph?????

I really wonder 'where' do people get this insane speed. Here in WA state, lots and lots of twist and cops plus, the most important, other cars.

A-Spec has done great work for me: swaybars, HKS coilovers, and the car is lowered 2.5-3". Without the power steering the car does not feel squirrelly at speed.

I have a nicely paved, almost deserted highway near the house. It has some curves and hills before a long straight that ends on another highway's entrance. I've done 165mph with a police officer as my passenger. His comment was how stable the car felt at that speed.

And yes, new SO3's! -Thanks Sean.

BTW: The PowerFC Boost Control Kit is here!

Help me choose an exhaust cut-out:

Beware of those things. I know someone that melted his at a track event recently. The manufacturer is honoring their warranty (he specifically told them about the exhaust temps) and will have to put in a different valve that a rotary won't melt... I don't remember him saying whose valve he used, but what worked for a high performance V8 didn't fare so well on the rotary, and both of those have similar specs (Aluminum body -- http://www.suppliersonline.com/prope...1.asp#physical -- which melts at 1000F, according to that link).

I know of PFYC, they support our local club's track events.

I would probably advise against the Cut out. Not unless you have a map tuned for both the exhaust and without. The fuel needs change and the turbo will spool a bit higher with an open exhaust

Thanks for the heads up & related information. I will make sure that it won't melt and we will be tuning it at a dyno. The PowerFC will hold 2 maps.

Is that because of the boost controler kit?

CCarlisi

What is the basis for that opinion?

DrPJM1

According to Dave @ KDRotary, and Steve @ A-Spec the PowerFC will hold 2 maps. You can load different maps with the laptop and associated software: 15psi w& w/o cutout or 93octane & 100 octane.

The boost control kit is for controlling boost above 15psi.

The exhaust cutout is for bypassing the midpipe and catback.

Sure, your LAPTOP may contain many maps, which you can load into the PFC at anytime; the PFC itself does not contain 2 different sets of maps. In order to switch maps you’ll have to use your laptop and Datalogit to load another map. An alternate solution would be to create fuel maps with both the cutout open and closed and then calculate the percentage differences between the 2 fuel maps. When you want to go wot with the cutout open just change the pim voltages to the percentages you calculated. This method would allow you to change the settings via the commander without carrying around your laptop to load the different map.

Good luck with your next run. I'm looking at a GT35/40R myslef. Keep us posted.

Regarding heat issues on the electric exhaust cutout:

From McCord Consulting Group, Ltd

"We have them on wankel engines without any issues and also on turbo charged engines. The main portion that sees the heat is made from 303 SS. "

Any new news?

I'll be heading back to A-Spec for installation of brake backing plates, PowerFC boost control kit, and electric exhaust cutout. We will control boost to 15lbs on pump gas and beyond on race gas.
