Hehe this is so funny.

Cul202 is right. Post the dyno chart and then we can see what you actually got, maybe u r reading the wrong scale on the graph? It sounds like you are reading out ur max rpm, if you are looking on the right hand scale?

Can you tell me what rpm your car does at around 130km/h? I can work out an exact value if you tell me that. I don't know your wheel diameter, so can't really calculate it, but I'd say you'd be around 450Nm (using a probably dodgy assumption of 4800rpm for max torque).

was in 4th gear not to sure wat rpm would of been doing at 130km. my limiter is set at 7300 and he hit that on the power run which was at about 170kmhr. im dumb at maths haha cant work much out

my wheels are have 255 35 18 tyres

Ok, using your wheel sizes (since that's probably the best way we've got of working this out), I used an online calculator to get a wheel diameter of 636mm. I have absolutely no idea whether this is accuarate or not, but if it is, then 130km/h should have happened at 4480rpm.

Using that, you get 479Nm. That's a lot of torque at the rear wheels. Then again, so is 258rwkw, so it's probably pretty close to what you are making :P

      Pipe from Greddy FMIC to Greddy intake manifold (RB25)?

      By jacobzking · Posted

      Does anyone sell a pipe that's made to go from the Greddy FMIC kit for ECR33 (RB25DET) to the Greddy intake manifold?

      Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Steps to DIY sanding car back ready for respray....

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.
