Only once have I opened mine right out whilst having it mapped on a private road.
Can't remember the RPM's but the peak speed recorded on the Apexi PFC commander was 246 KPH.
152 Mph according to Google calculator.

Sounds like the car hasnt been converted to mph (which is illegal btw in this country), though easily fixed
Gearing plays a part, it is dependent on that to what your top speed is, also 360bhp but not with a front mount?
I would suggest going to a speciallist and getting the car health checked, if the ecu doesnt have a piggy back chip then its going to be no where near that sort of power (the slanty top mount is lucky to push 300bhp+ let alone 360
), plus your injectors may well be maxxed before then (your standard car should be 250ps)You can also ensure its got a rear foglight (that works), that you can have your speedo converted to MPH (so it reads correctly and doesnt go off the clock
) runs healthily and isnt running lean/rich/detting its little pistons to bits

To give you an idea of 6 speed, mine at 8000 rpm in 6th (UK box) top speed is 197 mph. I would need over 2 miles to achieve it as Marham runway is 1.6 miles long I believe?

most cars won't pull top revs in 6th - certainly unmodded sti's/ wrx's etc won't.
Skull's/ Clive's would get most of the way there but that might even struggle at the real top end due to wind resistance increasing as a square of speed.
To put it in perspective, Andy Forrest's old StiV needed circa 800bhp to do 210mph...
My 450bhp p1 on an 04 6 speed was pretty much flat out at 164mph/7500rpm rev limit on GPS on Marham.

The description I heard that put it into perspective was that when you approach speeds like 200mph the wind resistance is so high it's like trying to drive the car through water.
Gives some idea of the massive power & aerodynamics required .
