on who's dyno......

your injectors are "in theory" good for around 220rwkw with bumpt fuel rail pressure being that they are 270cc = 270hp (flywheel) then take away say 25% driveline....

other than that .. u can get stock injectors to make 250rwkw ......A). if your in Perth....B).the dyno is special ....and or both

How safe was it to run that much power through your stock injectors Simon? could they run anymore power? I'm getting a hypergear TR43 fitted as we speak and I'm getting a remap through speedlab once I have run it in. If I can get 200rwkw safely, I'll be a happy man. I'll be giving feedback on the turbo kit on the RB20 and I'm hoping its not too laggy. The 5-0 Laurel ran this turbo and apparenty spooled 300 RPM later than a VG30, which is pretty good for a 440 hp turbo. Here's a list of my mods:

- Hypergear TR43 turbo

- FMIC

- straight through 3ich exhaust

- Bosch 040 fuel pump

- turbotech boost controller

- 3A racing pod filter

- HKS SSQ BOV

I'm keen to see how much Jeff can extract from these minimal mods. I plan to run injector cleaner before I get the dyno and change the fuel filter as to ensure fuel supply is as good as I can get it (cheaply). I aways run BP or Shell 98. Feel free to offer opinions or ideas.

^ I want your car!

anyway, 250 rwkw on Rb20 injectors? now I've heard everything! So do I need an aftermarket fuel rate regulator to get more fuel pumping through the injectors?

Using a 2:1 malpassi reg, it will build a higher rail pressure, and alow the injectors to flow more fuel when open, So the 270cc injectors become more like 400cc at say 60-70psi rail pressure

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.

      First thought is to use a ram mount (to hold the ipad) + windscreen suction mount. The arms on the ram mount can be as long as you like, should be able to position the ipad pretty well with that setup.
