Anyone -7 Or -9 An Rb28?

[mr skidz]

I haven't seen it yet lol

I can post a dyno graph of my E85 -7's for comparison soon also if wanted.

I have the same, my graph looks pretty average but is awesome to drive on the street.

[mr skidz]

If you have a stroker with -7's yeah then by all means post it up please

[Anfanee]

nah both standard 26.

Interested to see the difference on a stroker 2.8 vs E85 2.6

[mr skidz]

Pm me your number. I found it on my laptop but can't upload it for whatever reason. I'll SMS it

did you send it piggaz, nothing came through

[mr skidz]

Here's the dyno courtesy of piggaz.

Says petrol tune, 20psi, RB28 GT-SS and apparently had long duration cams.

Looks nice & fat

Looks like a good setup.

fark that thing would be beautiful to drive!

plot a comparison chart if you like

Imagine what it would look like on E85 22psi+!

^WITH A GTX2860 compressor wheel instead of that 1

I know what I'm doing when my motor goes.

[Piggaz]

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!

Wish the speed reference was revs instead easier to read, anyone able to give rpm reference points?

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.

[mr skidz]

Why would anyone use 3rd, not even wheel/ tyres would simulate a proper 4th gear pull.

Wouldn't those dots on the map represent rpm points?

Last dot meaning 8k?

Out of interest, what makes you say it is in 3rd gear?

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.

Hmmm I just look at it again, I'm an idiot. Thanks.

I agree.

Real world experience In this car would be the only true testament.

Even if it doesn't make more than 360kw peak it would have such a absolute meaty power band.
