thing is.. according to the dyno graph, it only runs lean up top, and by then its already made most of its power...

so its power isn't really coming from the fact that its running lean...

in other words, the rb20 is makign power for another reason. because its just in really good condition? possibly..

rb20 ftw!!!!!!!!!!

where's Roy? he'll jump in here soon for some rb20 lovin :D

Yeah im going to get a new Fuel Pump very soon. Then finish the zorst off with a 3 inch Front/Dump pipe and Hi Flow Cat. Raise the boost to 14psi and get a tune. Should be sweet then :D

Thats pretty good Matty boy! Now take it down the drags :D

Yeah it is running lean but the power is still up there before it starts running lean...

I might get some new tyres next week and take it down the 1/4 Mile :)

MATT nice work and it does look at 150km's you hit the limit of the fuel pump, BUT there is a posible little thing you can do to help will the fuel pump until you can replace it. That is to run a good heavy gauge power supply wire to your fuel pump as the standard system normally has to much volt drop across it (meaning your not getting full 14v charge volts to the pump) you can use the exist power system to switch a relay controlling the heavy gauge if you like and also ground the pump well. This is not a total solution but can offen gain quiet abit of exa performance out of the exist pump and will definitely help went the new pump going in. (voltage to torque ratio is a square root relationship meaning a little voltage drop will lose a lot of torque).

As for be lean BS running 12:1 through the majority of the power range is great and safe, and at only 12psi you could quiet easily run leaner without a problem. The only problem is the lean out trend at the end as you have already identified.

pete

ps i run 12:1 at 500 to 530rwhp for 2 years at 18 to 20psi no problems.

Nice result! I pulled 195.4rwkw in my 32 and thought I was doing well... but you don't even have a fuel pump or tuned ecu!! Must be happy about that.

yeap, and you must be happy about the wanker dyno operator giving you bullshit figures.

Unless your factory ECU has been remapped, and the turbo either high flowed or replaced with a RB25 turbo, then your figure is bullshit.

I bet any of these "figures" are barely able to pull over 100mph down the quarter.

ok matt is running an r34 steel wheel turbo and i was there it did pull that power and have been in the car and it feels as quick as mine, i have an r32 with an rb25 making 197 rwkw. i have no doubt that the dyno is reading correct

It was also run at the pole position dyno day so i doubt they mucked the figure up when my car was run before matt and a soarer ran after matt and power figures for both my car and the soarer were around what they expected.

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?

Thats an awesome result. Must be a relatively fresh engine. My question is how much difference in power output could there be between a fresh engine and an engine thats starting to get tired? In fact i started a thread about it!

Your questioning Hyperdrive's (im guessin as its in Malaga) dyno??

It use's shootout mode and is known as a very realistic dyno, doesn't read high at all dude.

Its well known that shootout mode applies some exceptionally poor correction making results higher than they should be.

demit, how come i get 167, with more mods, on 14 psi, on a engine that so many people have told me is in really good nick.

because yours is realistic dude :)

I'd reckon you both would run extremely similar times down the track...

And same dyno same day, you'd both have power figures close to each other :D

Im going to the drags very soon and when I get my quarter mile time it will give you something else to cry about!!!

He isnt having a cry about anything and he actually owns a rather quick car and knows what you need to do to achieve that sort of power... He is being realisitcs considering your modifications. So either there is more there that you are unaware about or its possible the reading is incorrect.

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
