nothing to back it up but theres a few over here been running them for years with no probs and a greddy one looks like its got less volume in it,theres no doubt the greddy is better mainly because you can fit a bigger throttle body
is that bhp at the hubs or the fly,and i see what you mean about the graph and thanks but i'm still going to see if it'll go to 12psi and in the meantime i'm looking at buying a gtst engine to rebuild,and whats your opinion on water injection,thanks john
when under boost the whole plenum is pressurised and not all intake valves open at once these intake runners are designed to suck not have air forced in them,i've heard on a forum somewhere theres been tests on these mods and the greddy one only took over at high bhp can't remember what the figure was or where it was but this engine will never get great figures with a high cr,ah and it costs nothing to do if you know a welder
theres lots of these plenums over here with no probs,and theres no way you would get as much power from it as you would a greddy one because its only got a standard throttle body,i have got a greddy type one but theres no point in using it until i lower the cr or blow it up and put a rb25det engine in it or if i smash the car i'll just buy a gtst and swap the bits over and in the meantime its all fun
8.5psi but i've added a turbo elbow downpipe,tubular manifold and splitfire coilpacks and thats it i'm hoping i have not got to lower the boost as it will raise up
i take it by what you mean about clutch fan its our viscous fan the viscous fan does not have any effect after about 30mph so ithink try thermostat first then radiator assuming there is coolant in it. and i am from the uk so the speed may differ
take a look, any comments welcome,power fc,480cc injectors,fmic,modified plenum,oil cooler,255l fuel pump,air filter/pod,de-cat,de-cat back 3" to3.75"xs poer exhaust and kenlowe fan
yes i know,just trying to prevoke an interest,i cannot seem to find any n/a power figures anywhere close so i was hoping somebody out there would tell me different you should/hopefully get quite abit out of one without the turbo looking at motorcycle engines
but its still an n/a engine internals still original still high comp,just trying to find out what power can be gained without engine alterations i am sure some of your are interested in doing the same
hello there,i have an r33 rb25de with turbo fitted running at 301.5bhp ath,i see you do quite a bit with na's down under and i've noticed hesh as been asking lots of questions,but the main question i have is who as got the most power out of an rb25de/rb25de+t and what mods they have done to get the power,many thanks john
