i was thinking about doing a 0 plate in my truck with a valet switch, the question is. will i lose much driveability with this set up?i know of several people that run 0 plates so fess up. mike

 

How would you go about doing a valet switch?

 

i was going to use just a 12volt solenoid between the intake and the afc. or could blow the buck for a variable one the guy is selling in the classifieds

 

But what all involved in it. How would it decrease the power without having a computer? ???

 

A valet switch doesn't let the injection pump &quot;see&quot; any boost.<br><br>It simply blocks off the passage between the pump and turbo.<br><br>It would have an effect similar to disconnecting the MAP on a 24V.<br><br>BTW, I'm curious also, as a friend of mine might be doing a #0 plate also.

It should work just fine, I have a #0 and a valet set up from Piers although the valet hasn't been installed yet. Cutting off the boost from the AFC make the lever arm on the AFC the plate. Piers does most of his towing with the valet engaged. On high HP trucks and the proper adjustment of the AFC it limits you to 200-250HP.

He's much higher than that now. ;D

 

Mark, I said high HP, not extreem HP trucks. Piers could make alot of HP with a electric fuel pump and spray nozzles.

 

A 0 plate will work just fine with a valet switch, remember that in valet mode the plate is not even being used, the way to take power away from valet is AFC housing, DV valves, or injectors as those are the only players.<br><br>BOTW, I made 433/868 in valet with small DV's and the AFC in the middle.<br><br>Jim

 

Good numbers Jim. I'm guessing this is with the twins in valet. Piers numbers were with a single HX40/16. ;D<br><br>I know of 2 more guys that are right beside you in the 690's and are also 12v's. Great job Jim.

 

due to my injectors, turbo, and tranny, i'm not at the higher hp levels, but i do run a #0 plate. sure, i control fueling/smoke and egts, but i prefer that sometimes. i CAN run around with no smoke, but i usually let out some. and i do smoke pretty good at WOT--i leave nice big, then long clouds with only upwards of 315hp or so. i don't run a valet switch yet, but i've been thinking about it for simply cruising around town.<br><br>#0 plate driveability? fine. #0 plate with big injectors...well, then you'll probably need a valet.<br><br>Tom

 

I know of 2 more guys that are right beside you in the 690's and are also 12v's. <br><br>Yea that rascal is going to knock me off the throne here, even more so when when I give him my next R&amp;D results next weekend or there shortly after. Need to clean up some more smoke and we both know how I'm going to do it just needs the funds. See ya!<br><br>Jim

 

i just have many times that i put out much more smoke than i want at the time, i was thinking i could run with the valet switch on 95% of the time and keep the smoke down. and get the extra fuel when i wanted it. mike
