im going to be purchasing the tork tech adjustable over flow valve. anyone using it and how is it working for you?
 
The adjustable one is not recommended, get the 60 for street use. I am running the 60 in my P24V and we had a 70 on my little brothers for pulling and with a 40psi spring in the air dog it runs 50 psi and pulls down to just under 40 psi on the track. Thats running the 70 though which is not a street usable OFV.

ok whats wrong with the adjustable one, just so I know? (thats whats in mine).
 
yea if its adjustable why cant i just set it at 35psi? but then again the 60 is 25 bucks cheaper...
 
I was told by hte owner they arent as relaible and don't flow the same as the 60 or 70. Also he said that the 60 is the best way to go for an agressive street truck. And after running a 60 in a compound turbo truck and the 70 in the puller, those are the only two ill be purchasing in the future. 60 for street and 70 for play.
 
I run the 60 with a 40 psi spring in my AD150 and it works good. No spring to wear out like the stocker so one less thing to worry about.
 
ya the tork tek that i got just has a hole in it......no spring, no ball, no moving parts at all

i also have an AD165
 
The adjustable is good for the stock lift pump and with a pusher feeding the stock lift pump. As far as I know, the non adjustable ones that don't have a check ball are meant for electric supply pumps.

I tested an adjustable prototype on my 97(Raptor 150 feeding the stock lift pump)vs my Bosch OFV with extra shims and a stiffer spring, I did the swap while it was on the dyno. The TorkTek made more power from 2100 rpm all the way out to 31-3200 rpm. Peak gain was 16.5 HP with a maximum gain of 28 HP.

I was reading on their web site about all the different valves and pressures they will produce and was just wondering why they say that certain valves can not be used with a fuel systems and othes have to be used with a fuel system?
 
im not 100% sure but i think it has to do with too much pressure? someone care to enlighten us?

Click to expand...

He told me if you used a ofv for stock lift pump with a airdog it would bypass to much fuel. I believe the one for airdog of Fass has either smaller hole or a stronger spring.
 
That was kinda what i was thinking also, Just didn't know if the 40 would still work as it is intended even if i didn't have a fuel system.
