Rb25 On The Dyno..decent Result From Stock Turbo ;)

[Simon-S14]

Mods are cooler and exhaust, its in an R32 and everything on the motor is stock... except for the RB20 remapped ecu thats running it.

Dyno run with the 33 ecu was a hell of a lot less. As we all know the stocker hits R&R with raised boost. Now ive got loads of midrange torque and driveability is sweet as.

For the bucks.. its a sweet upgrade for those 33 owners looking for some more poke... chuck those 33 ecu's in the bin.

[RB30-POWER]

nice result mate.

i don't know why people bother with the standard ecu either, its useless with anything above standard boost pressure.

[NYTSKY]

Exhaust,cooler and chip 213kw?????

What are you running 2bar

[Simon-S14]

just under 13psi acctually. look at the dyno sheet.

[CEF11E]

Those are some nifty results simon. what are you doing to control VCT? I can see it it coming on at 100kmph so in 4th with your diff ratio i am guessing that is around 3700rpm?

really keen on this as i may be going a 25 shortly and would like to retain my ecu and harness

[Simon-S14]

forget about retaining the loom, its a fair wack of work just to do it. Just run the 25 loom with a 20 ecu and you'll be laughing.

No VCT here either, its off and not really needed. Cant say ive noticed any lack of low down.

My rb20 with slide highflow was making 225 rwkw on 16-17 psi with stock injector / afm /remap then i swapped in the 25 which now makes 10 kws less, with stock turbo and had an insane amond of midrange torque compared to the rb20..

Overall im pretty happy with it.

[2rismo]

Awesome stuff Simon!

[1400r]

awesome result Simon Im gonna be running a tomei intact cam so I think I'll be VCT-less anyway with mine

[Simon-S14]

what size is the cam mate?

the VCT is only on from 1500 to 3500 or thereabouts, so really it only helps off the line, once you play with timing and boost you really cant tell the difference!

[1400r]

unknown Telly gave it to me when he worked out it wouldnt fit in his 25de

as they were 33 cams one was a 256 hks thing the others a tomei supposedly

could find any info on it but it did have b673465 or something like that on it so sounds like tomei

he's now gone 26 now anyway

[R31Nismoid]

I'd be wary of running 13psi with the stocker as you drift the car yeah?

Just a bit over the side of caution, had to see you have it let go!

[Simon-S14]

Yeah it gets drifted, ive kept it under 1 bar which is to keep it safe, Should be safe at just under 13psi i would say.

haha turbo tune dyno..... should make 190 everywhere else Nice curve though.

I just say it because i've seen a couple turbos @ 12psi let go on track days.

And others who had killed them @ drag days (12-13psi also), and the drag ones are even less time/heat.

Some last some dont, guess its luck of the draw on that one

same with soarer's i got a friend been thrashin his poor ceramic turbos @ 14-15psi for nearly 2 years no drama.... but his brothers didnt last a fortnight... lady luck is a bitch

Prob been a while since youve been there but they now have the most accurate dyno in Adelaide. If i wanted a high reading i'd go to tilbrooks and wow people with 240 rwkw's from the same set up

[salad]

Yeah, Turbo Tune's dyno is only a few months old now. Comparable to Graham West's dyno now

[Mr. iNFMS]

Hmm might be worth givin them a shot. I really want to check out GWW dyno. All my mates got decent figures.

Congrats Simon.

+1 recently had mine dynod there when jeff remapped it and before the remap it pulled a little bit less to what it did at boostworx with the same mods. as said they have a very accurate dyno.

that result is very impressive, if i ever get the $$ ill seriously look at going RB25.

[Simon-S14]

for sure, the RB25 rocks, and why bother running a PFC or forking out for other stuff when you can just simply run a remapped Rb20 ecu
