Hey lads, What are peoples experience when it comes to wrapping the dump pipe and back pressure? I realize it would be better if it was coated or ideally pre turbo, the dump pipe will self destruct, etc
Modded Garrett 12lb fits too Bit of mucking around but actually allot easier than I thought. Now with the front cover hosed straight to the actuator I have 13lb at 3500 rather than 22lb. With no preload only enough preload to not spin the gate and adding 15lb, this was how much it was opening before n Now with a bit over half a hole preload (10psi) the garret open this far with 15lb added
Yeh the more I think about it, it points to the actuator. I thought I had a spare 12lb I could play with but my bro lost it kn'fuq!! Lol Just played around with a standard bf actuator and found it begins to crack at about 5-6 lb and is fully open by 10lb so that's 4lb added pres.to fully open. The presicion actuator begins to crack at 11-12lb and is fully open at 36lb, that's 24lb added pres. To fully open.
Gtx guys just using the 12lb actuator from their previous setup or does the Gtx come with a new actuator? If it does come with a new one, do you know what lb it is?
Kinda what I was thinking too. sh*t part is it's not a str8 swap I would have to modify it a bit. Probly would have to pull the turbo out at wk n do it all there.
Just tested what psi the actuator requires to open the gate fully and it took 36psi to touch the end of the stroke. The actuator begins to open the gate at 12-13lb. What PSI would 1 expect the actuator to fully open normally
How is everyone else going with boost control with this turbo? Appears mine would like to run 20lb when if should be less. Actuator is adjusted loose as sh*t + it opens up properly on the bench. Bac pres. Is 3lb in the dump at 4g, 5lb at 6g
