Default Voo-Doo possibilities

Simple question. I've seen a very very small amount of miatas running high 13's with a voo-doo box. My question is, Is a low 13 or possibly a 12.9 quarter mile possible with a voo-doo, (on super sticky tires and low 60' time of course)? What would it take boost wise, turbo size, injector size, etc.?

I dont live my life 1/4mile at a time. I have no idea how to convert fueling needs into time @ speed.

The ONLY thing a voodoo box does is increase injector pulse length. That's it. It just leaves the injectors open longer when it sees boost.

Most guys running voodoo on an othewise stock fuel system (specifically stock injectors) need to max out the settings of the box to run the stock boost of a 2554r. Swapping to a 2560 and the voodoo will be completely maxed in it's capability on the stock injectors to provide enough fuel for safe AF's... and that'll leave you for absolutely no margins. Switching to bigger Toyota injectors will let you turn the settings down a little, but no way I'd run more boost.

With something for timing like a Bipes, some Toyota 310's, an IC... you should be set for 200whp at around 10-11psi on a 1.8. I wouldn't turn it up anymore than that for safety. Some guys claim to run 12+psi on a Voodoo setup, but I bet they're up in the 13's for AF... not my cup-o-tea.

200whp will get you into the high 13's... maybe mid 13's with some added lightness/Torsen/slicks.

If you really wanted to try something new, just stack 2 Voodoo boxes together like guys do with PCPros.

Please note that anybody at FM will laugh at you if you start to stack Voodoo boxes

Samnavy's summed it up pretty well. The limit's going to be around 200 whp. I have no idea what that means in terms of 1/4 mile times though.

BUY MINE BUY MINE!! It will totally get you into the 6-7 sec range because we all know that using two of any electronic device makes you go twice as fast. I've heard if you use 3 voodoo boxes and 5 pc-pros when you hit 88mph you jump to the finish line.

I pulled a 13.8 quarter mile at 6psi here, at 9+psi I think you could get low 13's easy.
