319rwhp Standard Turbo! (maybe)

[teejay]

im not arguing with any of that, im more arguing the original post that a stock 33 made this sort of power.

[Wildcat]

The car that i am talking about we still have so there must be two freak R33's in Perth!!!

[Miller the hoon]

I pulled 242rwhp with only a pod and 3' exhaust out of the turbo in an auto with the rb2.5t on psi s dyno in perth

then had a front mount and eboost and did 244rwhp at 8 psi and then 250 at 10psi on xspeeds dyno

both places said they had never seen an auto pull that much with thous mods only

my rb25 made 240 rwhp the with a stock r31 na exhaust and no cooler on 9 pound when my i got my 31...

stock airbox and all.

Ignition system seems to play a part in the power differences perhaps.

I notice that many of the curves are similar on 240/50rwhp cars to the 300ish ones, with the difference coming in up top. If the spark isn't as clean this could account for the power difference. The coils and wires under the cover get very very hot and this effects resistance and reduces the efficiency of wires over time with heat cycling.

[rev210]

Also whether the bonnet is up or down can make a difference too.

[teejay]

your not going to find 60-70 hp from bonnet being up or down.

[kamakazi]

ok my rb25 is making 267.2rwhp with minor mods on stock boost ie: zorst cooler and safc.

[noise]

no way r33's can make that much power.

the above poster is claiming 267.2rwhp on stock boost stock turbo, HELLO THATS IMPOSSIBLE.

r34 gtts with running 12-14psi with powercf, hi flow exhaust etc etc are only making 260-270HP on the stock turbo.

with boost cooler zorst, my 25 went 272 rwhp.... no ecu

[Miller the hoon]

teejay whos dyno was that done on?

james

[noise]

I am pretty sure that 25 neo's can only do 195-205rwkw max from stock turbo.

Thats 261.50-274.90rwhp.

how is an older less powerfull rb25 going to put out more power with fewer mods?

it isnt, stop talking shit.

or point me in the direction of threads of people posting dyno sheets to show otherwise.

[teejay]

i dont know why yours didnt make more then 270 rwhp

Shall I direct you to threads showing you this? how about you go to a workshop with a database of dyno sheets and look at them?

I didnt even own the car when it made the power, so i have no need whatsoever to talk it up. Those numbers where made on a DD accredited dyno

The car had

A garrett cooler, not gtr sized, just under.

A mettams morley dump and front, leading into a apexi cat back. 3 inch hi flow cat

11 psi

Walbro fuel pump

KN air filter

s2 motor

manual

standard timing

272 rwhp.

www.antilag.com/personal/tom/my31 for pics of the engine bay etc, so you can see it wasnt packing a hidden t88 etc.

tj

and back to the argument ... 319 rwhp is very very very hard to believe

umm ok...

im not saying 319rwhp is possable...

but why have many not just one or two, rb25 run between 280-300rwhp on stock turbo?

just because ur r34 didnt make it, doesnt mean its not possable for another rb25 power cars to do it

i would have thought there was a few psi more to play with in the r33 stock turbo vs the 34 due to the nylon wheels . that would pretty much negate the extra stock power of the neo

Hey James! man hows that happening? I only got 202rwhp with 3" exhaust & POD! Damn I'm pisst! What PSI was it at b4 FMIC etc?

[N I B]

Back to the basics,Im sure there not stock but they sure look untouched.

NEO engines have nastie combustion chambers for polution reasons and will ping at less timing than an R33 RB25.

Some shops are not aware the NEO head is different,A few weeks ago a shop removed the head of a NEO fitted to an R33 finding it looked different told the guy the head was an NA head and had to be replaced.

So yes theres lots of misinformation around.

Some strange things have happend to new cars like in the early 70s Fords GTHO Phase 4 was shelved by the government (AS were GM etc)

so ford stuck some parts on a 2 door falcon and tagged it RPO87

the rest ended up in ZF Fairlanes without the new owners ever knowing

and over the years we saw stockers with Noddy iron 9in diffs winged sumps and 4V heads with 780cfm Carbs etc so who knows what may have happened with these cars,Prolly modded very early in life by very carefull mechanics?

[rev210]

got to remember that the dyno is a tuning aid at the end of the day. There is some value in relative comparisons but, not something people need to get hung up on if their car is doing what they want on the road or track. If your tuner is handing the car back to you with improved power characteristics this is what matters.

Some R33 gtst 200rwkw+ cars have run against my old R33 gtst (dyno of 170rwkw) and had an ass whipping both in 1/4 mile time and terminal speed.
