What is the highest recorded "realistic" figure being pushed on RB using -5/2530/-10/RS - 0.64 hot sides?

60's would want to hit 420 rwkw considering it's not too hard to do that on bog stock -5's on E85 but without the brain damage.

Borg Warner do a 9174 now. Still sitting on the fence as to how that will go. 9180 with the 0.92 read IWG, soo much compressor for that small hot side. You may have to bite the bullet and externally hate the gasses and go to a larger rear housing?

2828.5 cc 87 bore x 79.3 mm stroke. Poncams are long gone.

Feels so much stronger than before, 100%. It's going to be a good thing when it's turned up!

Picture, post the picture!

Chuck up your graph again mate?What pressure are you running to net 500 kW?

No. There is a graph from very early on in the tuning process. 10 psi at 4500?

9180 1.05 or 1.45. Do it! Gearbox ordered yet? That stock one will last a month if you're lucky.

Really? From who?

I'll know more soon.

Going off what Brett has said. 22 psi was reached at 4300 RPM which on that graph is 105 km/h. It's making just on 300 kW at that point.

You're assuming the run goes to 8000 rpm.

Not really that exxy really though . A set of AFM delete pipes costs more

Throw that trash as far away as you can! As above, well worth it!

Until you get up and over 400 kW and it sucks the filter in. N1 GTR's car used to do it. Not sure if they ever fixed the issue. Nice and shiney though so looks the part. R33/R34 airbox is good enough. Spend the money elsewhere.

What's the size (obviously 18 inch) and offset, fatman?

Im sure it may make a difference with the reduced angles of the two fronts merging, however, spend $100 on the "twin turbo pipe mod" and put the extra money you saved into "the future head mod fund".

Race car now. AC gone.

Where is it coming from?

Because the dyno run went to 180 km/h which is the top of 3rd in a factory geared box. It's making peak power around 160 km/h which is 7000 ish RPM. If it was in 4th it's peak power would be like 5500 RPM (rough calcs) which isn't right.

That run would have been done in 3rd gear. That's 22.5 km/h per 1000 RPM. (Close enough when factoring in tyre sizes) 90 km\h is 4000 RPM.

I'm sure the dyno sheet would only tell half the story of how this thing behaves. Drive it through the hills with its tricky diffs and sticky tyres and it would be an absolute bullet. E85 and give it more boost through the middle would fatten it up even more but I'm not sure how much the peak figure would change. Definitely want a drive!
