Hi all ! how are we?
Im new to this site so first topic post!
I have a 1994 R33 Nissan Skyline Gts-t manual with usual mods, boost controller, Front mount,exhaust, pod, fuel pump and fuel Pressur Reg and Clutch, I recently put a garrat GT3076R high flow in and its very awesome! runnign 12 psi she sings. but planning to get an ECu put in and tuned so i can run more boost with safer levels as now the ECU doesnt quiet adapt to the higher boost haha
my question is , before with the Stock Turbo, when i would wind the boost up to 12 psi it you's to R/R (Rich and Retard) and cut but now when i wind it up i can go to 15 psi if i want and it will take it ! and wont R/R just wondering if there is some sort of Mathimatics going on there with the air flow? my boost controller is of the Throttle body so it reading is Correct....
its a spinny one has had me thinking about it for a while! could it be that it isnt actualy getting the correct amount of boost? in order for it to R/R.
I went throught the trouble of putting the older turbo back on to test and bam! 11.5 PSI R/R !! put the bigger flowing turbo on more power at same PSI with no R/R at all.
Its not a major issue, i would like to know if it could be doing harm? amd should i be worried? and if you have the correct answer to this?
Thanks!!
