Real value of Gillis vs BCS

[raywoo]

I know that many folks expound of the value of bypassing the stock BCS in favor of a manual valve. I have installed a Gillis valve and enjoy the kick-in-the-pants feeling when the boost kicks in, but when I autocross my SVO, this same feeling also greatly unsettles the car.

Perhaps using the Gillis is good for the dragracing folks, but wouldn't a properly functioning BCS be better for autocrossing? Wouldn't it make the boost come on more smoother and progessive and earlier?

The concept of the Gillis valve is elegant and pretty low-tech. Surely the engineers at Ford would have considered this when they decided to design the BCS as the way to moderate boost in the SVO.

Thanks

I don't use a Gillis .. but I do use a Manual Boost Valve. I also love to autox .. and when I do, I break out the handy allen wrench and turn my boost down. I usually keep it down at or below the factory levels (14-15psi).

You should consider a bleeder valve if you want to run higher than stock boost and autox. The bleeder will act just like the BCS (because that's basically how the BCS functions).

OK, I guess nobody is running in a stock class at the slaloms. That, or your competitors don't know what they're looking at!

The SCCA folks around here are on top of turbo cars... I get put into Street Mod because of the adjustable boost, and welded subframe connectors. It really sucks, because I have to compete with cars with many more mods than mine. Full cages, gutted interiors, tubular suspension, big brakes, soft compound tires, etc... I ussually only finish about the middle of the pack. If I get new tires before next season, I'm sure I'll be more competitive though. I only do it for fun, but I would love to finish higher. I've thought about getting rid of the connectors and putting in convertible chassis braces, and hooking up the BCS for racing... Then I'd be legal for the stock class or ESP

Hmmm, I thought all SM and SM2 cars had to run FULL interiors. I _think_ you can remove your rear seat, but the rest of the interior has to be there.

Also, aren't SFCs allowed in ESP?

Time to get another set of wheels (something aftermarket that is MUCH lighter than stock) and bolt some Kuhmo Victoracers to them. :-)

I dont think that SFC are allowed in ESP.

Out here in SoCal, I was running my totally modified track car in ESP because I wasn't competative, and they wanted more cars in ESP (for trophies).

However now that I'm a bit better, I run in CP.

SM I believe needs the full interior (minus the back seats).

Oh yeah, I also run the gillis valve turned down low (12-15 PSI)
