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.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
