Kr, C16 ?engine problem ?

[vette_c6]

guys ,, i faced a Zo6 Came From UAE

to be honest ! it was Strange ,,
1st of all
i relized that this car have been Dyno'd before
the Tuner for the Car ,, Runned it till 6500 RPM instead of 7000 RPM
the car made 470 RWHP
Headers Exhust + Camshaft gt19
227 / 239

.678" / .688"

114

the Car Was unbeleiveable in the dyno !
you can Hear the KNOCK
and you can see the Knock in the HPTuner
what i will do is to add fuel in the car
have anyone of you guys knows what is the theory for the C16 With the Fuel ?
1L or 2L with half Zo6 Gallon ?
i just need to confirm if the car need Fuel .. or there is an engine problem

cheers

hope i guys share the info if i missed something

NOTE : the older Tuner ( 1st tuner ) said its a FAKE KR !
this is a PART WOT i released the throttle when i saw the KR
AFR in this Run was 12
i leaned it up to 12.5
Still Same thing

the weather is hot ,,
the Car is Retarding timing because of the knock and the Temp

hope i get some comments

Comments from experience please

That motor shouldn't need that kind of octane. You could use it as a test to see if it's false knock but would go back to a lower octane.

High octane fuel burns slow and low octane burns fast. You could really slow down the combustion process to much and kill power.

Not to mention the lead in that fuel will mess up the factory oxygen sensors.

If your hearing knock its knocking! In that case you need less spark or more octane.

Also if the engine is burning oil....you can also induce knock.

C16 will be added to tank
Need to confirm the knock
-------
the thing is Timing is 19
because of the HEAT and the hot Weather ,, the Car has pulled 8 degree's
its 40c Temp over Kuwait
and also because of KNOCK the car even Start Pulling timing

i think this engine is modified With Compression more then 12.0
