rb25det plazmaman V std intake Results
Since this has been a very common question over the years of people actually wanting a proper back to back comparison of plenums on rb25 I thought I would post my results as I have done a back to back with no other changes.
Car Setup:
std rb25det
tomei 256 cams
hypergear ss2 turbo
e85
4inch straight pipe exhaust
PFC
z32afm
takashi 600x300x100 cooler
xpsurt 1000 injectors
Plazmaman Plenum
22PSI
As you can see from the results there is very little change with a few kw up top gained but generally the curve has remained fairly similar with a few spots slightly better and some slightly down. Boost response also remained the same. (Orange curve is plazma and red is std intake)
