Dyno sheets and discussion for UK Rotaries!

Bri what do you make of my dyno graph pratically the same as yours bar the mid range being a bit better on mine?

[bnaellis]

Here we go Brian dyno attached ignore the thick black line as that is my old setup, look at the thin one, comparing my power line to your its almost equal at the beginning
eg 4100rpm you are producing 108rwhp and I am Producing 112rwhp,
at 5500rpm you are producing 300rwhp and I am producing 325rwhp, so the Hbridge edging it here.
But by 6200rpm (cant be exact as different scaling is used) its equal again at 385rwhp
And still equal at 7400rpm when we both hit 470rwhp, at 8200rpm you lose 10rwhp whilst I am still the same,but to be honest there is hardly and difference, the pull is stopped after this.

Interesting stuff so if I was to bridge my secondaries does that mean I wouldn\'t actually get any gains on my current setup??

looks that way for peak power it be the same, you will gain in the midrange only.
Did you run WI on your dyno runs?

I think the difference in mid range is clearly seen where your secondaries are doing there stuff but I thought there would of been the same difference over a broader rev range.
I can also see where after 8000 rpm the bridge is more efficient where there is less time for the engine to swallow due to engine speed.
Torque curve is more or less the same too.
This time round I should lose a little power as I am putting a more restrictive but nicer sounding back box on my car.

No I was getting break up at first so I disabled it to put it out the equation.

So the main question is Brian will you be running next year against Timbo?

[silverrexman]

Blitz are you updating the the sheets,come on i want to see me at the top of the pile before some other fduker beats it:wiggle
So far its my only claim to fame,apart from when i was on the telly coming out of the courts:Giggle

[BlitzBoy]

lol okies I will have a go at it tomorrow I was just waiting on Geff to dyno the RX8\'s 20B engine

Mine will look nicer than Tim\'s I guess that\'s not hard really. But if Tim can get his engine probs sorted next year I don\'t think anyone would want to be racing him i\'m sure he will wipe the floor with all the competition. He will have a very special car for next year but I cannot say more.

Okies guys will be re doing the Rotary Dyno Sheet, it will be revamped, it be Top Twenty only, Twin turbo guys should created their own Dyno sheet.

[BlitzBoy]

what Turbo you have again Steve?

[AshRX]

ill scan mine later when i get in

[BlitzBoy]

need at wheels figures Ash

[AshRX]

was about 465 from what i can remember @ 1.15 bar ish

[Kash_]

^ very nice Ash especially at only 1.15 bar :eek
