What hurts a RB25DET motor? Boost or Power

[INASNT]

Real skyline??? Or as the rest of us define them 'the one that uses the weed wacker engine'

I cant recall a r32 with a rb25 and GT30 at PI???

[Roy]

Thats the thing R32s are pooftahs cars as well:) A real Skyline is a GTSR:)

[INASNT]

Only one I can think of is ashes, but he as the same spec GT30 as mine so it aint him :confused:

You sure u didnt eat 2 many of the wild mushrooms that were growing around the parking area??

What you are attemtping to describe is Average Power, if you do an Average Power comparison  between the 2 turbo configurations it will answer your question.

Im talking about traction v's low down power as in the described text

INASNT, same GT30 as yours and he doesnt have any traction problems. Though his car wasnt running its highest boost setting. Seat of Pants it still had good mumbo!

I somewhat disagree, No matter what housing you get your still going to get wheelspin.

Say we have 2 turbos, one producing midrange and the other top end.  Ok, both are going to produce wheelspin in first gear regardless.  Now, second gear, one produces maximum power earlier than the other, say 500rpm??  So one spins or 7/8 kmh before the other, lets say 10kmh it is then, so one spins at 60kmh and the other at 70kmh, one has more power than the other so in my theory they would spin about the same.  And the wheelspin you get at those speeds does not really slow you down.  Now 3rd gear, if you can get wheelspin you have a mighty strong motor, so i would say the midrange turbo would jump the top end turbo initially and then the top end turbo coming over the top.

i totally disagree based on my own car.

the .82 rear housing. If im smooth through first-second it will not wheelspin one bit.

And yes it was my car Roy was in

I have no traction issues at all. Just using 245 sumitomo's which are absolute rubbish for grip. And ive still got lots of squat

If the turbo came on much sooner, im sure i would have problems. I used too with my old t04e which was maknig a lot less power, but boosted just a bit earlier.

And true to form, the Bush bearing turb was like a light switch.

The my turbo on the motor is much smoother and progressive so it has bearely any problems traction related

one min its boost spike.

next its prolonged boost.

...........

i never said it was the same turbo

if you call two dyno runs a prolonged period of boost, then i wonder what you call a decent time between rebuilds .. 1000km?

']i never said it was the same turbo  

where did i say it was :looney:
