bigger turbo same boost now slower?? Help??
ok to start i have a d16a6 built with
srp pistons 8.5:1 (30 over) eagles log manifold 38mm tial wastegate w/ 10psi spring and no boost controller greddy type-s bov 2.5" piping 3" open dp godspeed intercooler delta 272/260 turbo cam arp head studs cometic head gasket no a/c fidanza 8lb (i think) flywheel lsd 6 puck unsprung clutch w/ heavy duty pp TT oil lines aem fuel rail with TT 440 cc injectors walbro 255lph pump basemap w/ crome ok the problem is that i used to have a .42/.48 airesearch t-3 turbo and i upgraded to a t-3/t04e .60/.48 turbo and now at the same boost level it is slower. I thought it would pull harder since it would have more cfm then the smaller turbo just have more lag but its not it is slower with more lag and the only reason i was thinking it might be is because its the same hot side but bigger cold side so it should spin the about the same amount except maybe the other turbo was more efficient at that boost level where the bigger one would be more efficient at like 18-20psi when the smaller is throwing out to much heat. Im just curious if there was another reason that i dont know about or if i am wrong, i just wasnt expecting it to be slower lmk what you think. Thanks for the input |

you cant just slap another turbo on and expect it to be faster without making any mods to your "basemap" / without more boost especially being larger on the cold side

dont keep turning the boost up. i dont under stand how your capable(if YOU did) put a turbo car together and cant figure out that changing mods it effects the tune.

ok well i called chris at xenocron and asked him since my tune was just a basemap for now if i should get a new basemap when i changed my turbo and d/p and he said no it wont make a diff just keep what i have untill i get it dyno'd so i didnt think it would have been the tune.
