Anyone here running a backpressure sensor? If so, how do you have it hooked up to keep from burning up the sensor from the extreme heat?
The tap was in the y-pipe at the turbo inlet. I ran about 3 feet of stainless tubing, put a few bends in it, and put the sensor in a spot where it wouldn't see a lot of heat. All per RacePak instructions. Couldn't get one to live and I've heard of others having the same problem.Bobalos said:I know it would be ugly, but couldent you run a tube off of the header & put the transducer 2 or 3 feet off of the header?
I've heard the same about double the boost pressure.Jim Monson said:I just watched to see if the backpressure was too high. I've been told that if the backpressure gets much more that twice the boost pressure your turbo is less efficient. So if you have 20lb of boost and 40lb of backpressure you're ok. If you have 20lb of boost and 60lb of backpressure something is wrong. Changing the a/r ratio can raise/lower the backpressure.
On my car I have a 1:00 a/r ratio. I want to watch the backpressure to see if a 1:3 or 1:5 a/r would help.
Good point, I hadn't thought about breakage. :lol:Jim Monson said:I want all the data, all the time. I'm greedy. I need all the help I can get. I also wanted to monitor how well the exhaust was sealed. If the backpressure dropped off it's time too look for leakers.
