The line that goes to the back can be eliminated and the port plugged. The "T" is not used. My UPR came with a plug.Need some help. 19 Roush and looking to put a UPR catch can on it. Anyone see this before on engine? The UPR does not show T-Junction for the dirty clean lines. Anyone experience this and how did you get around it?
I’m running 10 psi with a Whipple and bumping 100% duty cycle on a dw400....and you want to make 14 with the stock pump? If it were me I would log it and see how the pressure and duty cycle look.
okay sounds good, maybe i’ll just do the pump with a pulley and log it after to see how it turns out.
Thanks for quick response
Well if it were mine I would proceed very cautiously. That’s a lot of boost on 93 with 12/1 compression. Log every wot run. Start out just going, say, 3000-4000 rpm. Check for knock retard. Then extend to 5000 and check total timing and knock retard. Etc. I would expect 14-16 deg at wot at that boost level with the stock gdi pump and no interchiller.
awesome i will do exactly that. thank you for the knowledge
Hope ya breaking it in right!!
I think this one will be good the last one was burning oil from day one with 2.5 miles on it you could see blue smoke from the driver side exhaust.
I am glad to hear this. I hated to see you knock a hole in a piston with 12:1 compression, 14 PSI of boost and only 93 octane fuel.
