Place your bets (Dyno run)

[AndyMX5]

My ZX7R is going in for a Dyno run on Thurday.

So, place your bets... What power do you think it's making.

AFAIK it is standard apart from a Full Akropovic system which gives it a horrible hole in the power between 5-7k

Depending on results, it will be jetted shortly afterwards.

So, I believe they are meant to have about 110 at the rear wheel...

My bet is 90 rear wheel horse power with practically nothing below 7000rpm.

105 here!

[R1_JON]

106.7

[Busa_Rush]

108

[F.M]

109bhp...with a hole in the lower torque curve by the sound of it.

[RemaL]

101.776

[Ballon]

88 is my guess.

[Rawwr]

647,941.

[AndyMX5]

97 hp... at the rear wheel.

The fuelling must be way out.

IIRC mine made 117 at the wheel on RhinoDynos rollers back in '98 (full Ti Akra system). It ran a bit rough <3Krpm but was really crisp above that.

Get it sorted.

I win,

but as posted must be soemthing not right to get that

Yeah - the compression is ed on 2 and 4th cylinder.

Leakdown proved it was the exhaust valves (74% on number 4!)

If I'm lucky, adjusting the valve clearences will fix it.. But that's about as likely as hell freezing over whilst I win the lottery and get shagged by that fit bird from the Resident Evil movies all at the same time.
