Increasing redline on RB25

[N I B]

Melbourne is a very long way from perth.

Very long way just to prove a point??? Whats the big deal. Get your car on the track and start doing some real numbers not pub numbers!! Even a trap speed is good enough, that should prove your power.

It was a joke :wassup:

I will post of our street GTR 682rwhp and 141.5mph trap speed on normal road tyres.

Yes we have to even run a parhchute to race it again.

This is as driven and made 1 hp less at Cabin auto salon.

This is for those that think that RB25s dont make a shit load of power and high revs on stock cams and heads.Check it out.

Hi Steve, on this dyno graph the AT is 21 degrees and the IT is 52 degrees.

On BMan's, the AT is 25 degrees and the IT is 31 degrees.

Help me out here, I am confused :confused:

PS; There are a couple of other interesting differences, but more on that later. I am more concerned with the temperature differences first off.

The final power figure was after a number of runs, and the intake temps get pretty warm, cause when doing a proper shootout reading the bonnet must be down.

Argue with 141mph...

[N I B]

Remember last year Pauls stock motor won PAS dyno comp at 436rwhpwith the same turbo

but 411rwhp here but the under achiveing knockes bagged it then also but cant do as good themselves.When i take Pauls GTS to the track all the bull will stop!

Your point is valid!!

[GTS-t VSPEC]

Theo's GTR ran an 9.86@144mph on Nitto's, ND4SPD ran 141mph on old shitter street tyres, so the potential is there for a 9sec pass.

Should hear the thing at 10000+rpm.

ill be the guinea pig for this stupidly long-running debate

Im driving over there in as many months, and no doubt i'll be @ SST-Auto a bit checking it all out

[GTS-t VSPEC]

R31Nismoid, Get you car dynoed at a DD Shootout dyno over there so we can do and accurate comparison when the car comes over here:D

Where was the IT temp probe?

[GTS-t VSPEC]

IT probe is infront of the air-stream going to the pod filter.

So the air coming out of the dyno cooling fan was at 52 degrees? That's a hot day for 11th June (winter), even in Perth. :confused:

They might have used a radiant heater instead of a fan

I'm not sure whether there breed you dumber over there or not, so I'll repeat myself slowly so you may understand.

The probe is inside the engine-bay, in-front of the airpod, with the bonnet down. After 7 or so power-runs the air gets pretty damn warm in there, the fan is directed at the intercooler.

Time sydneykid built a car that shows his tru skills.

Really think he is a keyboard coward,Prove me wrong.

What about ND4SPD?
