Top RB20 Club... do you have over 260rwkw?

[Butler]

i run an r33 turbo and my limiter is set to 8k and it is very easy to his specially when sideways

[FATGTS-R]

Max power on mine is made at around 6,000rpm and rev limiter is set at 7,000rpm. Power doesnt dive it just slowly tapers down.

I agree with Roy about wringing the first two gears a bit more but my car is all over the shop in first and second and I always am bouncing off the limiter unintentionally.

I need to improve my driving skills/suspension/tyres before I will bump it higher.

[Sydneykid]

I have the rev limiter set for 8,250 rpm vai the PFC. the standard tacho shows 8,500 rpm, they are a bit optimistic.

cheers

[R31 POWER]

Off topic i know but what type of limiter does the pfc have? fuel cut??

[paulr33]

normal powerfc is fuel, powerfc pro is ignition

[legend01]

Ok after a long wait car is finally up and running again although still with restriction issues will post the graph and maybe get a bit of a disscussion going on possible causes tuner is still leaning towards exhaust as it is pretty quiet the other is inlet track somewhere anyway u will see by the power curve that there is a problem I just gotta find the damn thing

cheers Peter

have you got a cat? drop the exhaust after the front pipe and do a power run. Should be some difference.

[legend01]

Thought about doing trhat but it wouldn't have told me anything as anyone that drops there exhaust will make more power wheather the exhaust was restrictive or not but thanks for the suggestion

I wouldn't be complaining with that power level anyway.

Can you remind us what kind of turbo you have and bottom end?

Those are some mighty high intake temps! where do they stick the sensor?

[FATGTS-R]

You said the tuner is leaning towards the exhaust as the restriction.

But you then say dropping the exhaust wont tell you anything.

Huh?

[legend01]

It will make more power without the exhaust as any car will any exhaust is a restriction we did try this and it made a heap more power but that was when I was maken 238rwkw since the engine will flow exhaust gases faster with no exhaust air into and out the engine it not pinpointing where the flow hold up is but i think a newer exhaust has to be the first step as the intake side of things is suppose to be good for 450 hp well thats how it was explained to me

Interlooper the bottom end is stock engine has only done around the 65000ks mark as ive had the haed of for porting bores looked brand new so it was left alone turbo is a garrett GT3040R

[legend01]

update

from information gained it appears 3" exhaust will not flow fast enough above 250rwkw so just bought a 3.5" cat back exhaust will fit that and then try tuning again c if that fixes the problem

what brand exhaust did you buy? or is it a custom one?

[legend01]

bought a HKS second hand mainly to see if it fixes the problem firstly but its is in surprisingly good nick so

Cheers Peter

ok the engine is nearly done, it might be in on saturday morning, i have come accross a problem, i have one washer left over, i think its from the bottom end, its a silver washer with a tapered edge, its about 15mm across.

anyone got an idea where its from.

[boostn32]

well its nearly all done, just a few more bits, this is the engine that i hope to crack 300RWKW+ with. will it happen, u bet it will. its taken so long and its only a week or so away from dyno run in and full power tune.

[boostn32]

well here it is, the engine ive been building, this is the one i hope to crack 300RWKW+ with, its been so long and now its only a week or so away from the dyno run in and full power tune.

[Interloper]

ooo, this will be interesting

Is that a steam pipe manifold? looks solid!

[boostn32]

its a Greddy manifold, its very well made.

[Drift_Mulisha]

Yo everyone, just wondering if any of the RB20 owners with over 240rwkw have had engine failures or mechanical troubles when used in a circuit/drift enviroment? reason i ask is my rb20 just made 258rwkw @18psi (mods are listed here:) http://www.skylinesaustralia.com/forums/in...ic=103095&st=20 but the tuner recommended i only run with around 1 bar not because the tune wasnt safe, (it was detonation free at 18psi) but because the sheer mechanical strength of the motor could not take that sort of power continuously ie lots of revlimiter action in drift. Any opinions would be greatly appreciated, especially from roy & other RB20 heros who use there cars in circiut or drift where are they are given a pounding.

Cheers.
