I disagree with your comments on shootout mode,

My mates car made 214rwhp in shootout mode and 250somethin rwhp on a dyno that wasn't accredited but is a big company over here...

Each to their own i guess, all the serious modifiers use dyno's that are very close to each other over here with shootout mode :P

This came up on another website im on regually and we refer to this also!

Fuel curve looks like its been mapped, Stock Nissan maps are not like that so this may explain your good power figures.Rip the kick panal of and have a look.Fuel pump fault should have been lean at the higher power area of your curve but it does look like a tuner has been chasing 12-1 but factory they keep going down as far as 10s.

I believe to be a dyno tuner with the software you all have to be within specific specs of each other, i know for a fact there is less than 5rwhp difference between the 2 dyno's ive been involved with :P

Yep down this way there's 3 dyno's that read within a few kw's of each other then one that generally runs v8's that both times the blokes had the car on the dyno its thrown out a figure that is ~30rwkw lower.

Same shootout mode; dyno operator said its probably just software version.

Another bloke I know has had his car on the same dyno twice; once it made 214rwkw another time 230rwkw as it was strapped down different.

Well i guess your best goin on one dyno with one setting n stickin to that as you mod your car to see the actual diff's it makes on the same dyno to see how much your goin forward!

From what im told there few around me that peeps use are all fairly close to each other which is good for us

Mafia it sounds like your really f**ken Jealous of my RB20! Just becasue your RB25 wont produce that much power on those mods doesnt mean you have to have a cry!

And if you actually READ! I wrote that I have a R34 Turbo!! How about you put up your Dyno reading and your Mods and lets see what you get?

actually, I'm not having a cry, I'm having a laugh.

I had a RB25, PowerFC, FMIC, standard turbo, exhaust, etc. Made 209rwkw. Ran 105mph down the quarter, and was more than capable of running 13's all day everyday, and low 13's with a good launch.

But the time don't mean shit, I ran 105mph. I bet any money, my 210rwkw running 105mph, your factory ECU and bullshit 200rwkw will barely be able to scrape 100mph.

Dynos are a tuning tool. But somtimes, the figures are just complete bullshit, because dyno operators see people like you coming, bung in some high figures, and then you tell all of your mates, and they go there, get high bullshit figures, and yeah, the dyno operator has the last laugh because he has all of your money, and your down the track wondering why your "200rwkw" is only running 14's and 100mph.

I think that sums it up nicely.

Oh, and I'm not jealous... I'm running GT30 on the side of my car, its now making 250rwkw+. and running 12's with 112mph+.

Maybe I should bring my car to your dyno... It would make 400rwkw eh? (the funny thing is, it would still only run 12's and 112mph+ :) )

ok dude i have run my car on serveral dynos in perth and it only varies around 10 rwhp difference on the dyno's. my car pulled its expected power on the dyno so y do you say that it is dodgee when i ran 5 minutes before hand? as you can see non of the figures have been un realisticly adjusted at the bottom of the dyno. i can also tell you that his car is quicker than mine that is running an rb25... we will run it at the plex and i will place money that it will easly break the 100mph barrier and get mid 13's. i know this coz my car averages mid 13's and his car feels as quick as mine and has no troubles keeping up.

look im not wanting to start a shit fight or anything and i understand that i dyno is a tunning tool. When it is run down the 1/4 times will be posted

It should be in the LOW 13's or high 12's.

Remember it has a lot less weight than an R33, thats a key factor in it "feeling fast".

As for shootout, its been covered many many times before so you can go searching for it.

It adjusts the figures incorrectly, plain and simple.

Its same dyno, same day... or results cant be compared to the nitty gritty

I'm not trying to start a fight either, but just remember - My argument is based solely on the fact that you are running a factory and un touched ecu.

If its chipped or whatever - then your results could be fairly accurate.

I'll still interested in the 1\4 times, and the terminal speed. Keep us posted.

Haha yeah, well if ya live in Perth you should come down to Hyperdrive at the next shootout and see what you get. :ninja: Yeah im going to get a Quarter Mile time Hopefully next week when I get new tyres. I agree that its weird about the power output and it does seem like with that kind of power the ECU should of been tunned or remapped. Maybe someone before me got the ECU remapped or tuned...... not sure though.

Yeah we should drag at Kwinana next week kamakazi. See what quarter mile times we get :ninja:

Its around the mark.. even if it were reading 15rwkw high.. it would be what I would expect for mods boost turbo and stock ecu. So its not like its way way out. We must also remember the R32's stock ecu doesn't hit R&R like the R33 ecu's so they can be pretty much pushed until they hit fuel cut or most generally run out of fuel. :ninja:

Generally down here the R32's with r33 turbo's on 14psi tend to make around 190rwkw the injectors hit 100% duty.

Its known for the R34 turbo's to net approx another 10rwkw over the R33 turbo on the same boost.

So considering your afr's and boost your running.... I'd say it is reading a touch high. The attached dyno sheet was running a new pump, tuned ecu with injectors at 100% duty. Not to mention your almost making the same power as an R34 running the same boost. Now logic tells us the rb20det head flows considerably worse than the r34 head so you will need more boost to get near the same power figure.

My self.. simply bolting the same turbo etc on to an rb25 head I made similiar power on 5psi less boost.

Where does the R34 turbo make 12psi on the rb20?

Your run does appear to lack a little down low compared to the attached R32 running a R33 turbo so I'd assume its a tad more laggy than the one shown. In car it felt as if it came on hard around 4000rpm but was making decent boost from 3000rpm.

This was my run on the exact same day, same dyno, same operators. Car is a R32 GTS-T with 3 inch turbo back (incl. 3" cat), FMIC, pod w/CAI, GTR fuel pump, standard turbo. It spikes to 13psi and drops off to 11-12 (bleed valve).

Thats the standard ECU doing its magic :P

I'm still yet to get hold of a laptop to check consult for the AFM maxing out but I think its just naturally rich for some unknown reason. Eeprom burner and a wideband should fix that when I get some more money :P

Frost.. Here's mine with similiar mods except stock intercooler and a little fpr bleeder to lean out the mixtures a tad. It was running 12.5psi with a bleeder. 12.5psi was the most it would hold with the bleeder. By leaning out the mixtures it picked up 10rwkw. :O

Yes it was done in third for what ever reason. Later when I had the FMIC fitted I had it run both in third and fourth and fourth made 4rwkw more power, not saying this dyno run would have done the same as initially on the same boost with only an fmic and in fourth gear it made 155rwkw. :P

my rb20 made 253hp on one dyno then 251hp on another dyno with stock turbo, computer, and 1 bar of boost. it has also run a 13.5 @ 105mph. see it is possible.. i will post up the dyno graphs when i get a chance.

this is a rather old thread. But since you dug it up matt what times did you run in your car ??

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents
