That is pretty gnarly compression for pump juice, as for whether its too high...
Do you happen to know what was done with the ignition timing? I have a feeling there would have been some fairly dramatic changes to stop it pinging with that compression which may have affected it. Either this or it could be running really rich too. Someone with a bit more tuning specific knowledge should be able to help.

That is indeed pretty high for a streeter. Mine has about 9.9:1, and that is about as high as i would go with the rubbish fuel we have here.
The last NA engine i built had 11.5:1, and i had to run it on C16, pump fuel was a no go. However, a really good tune should see it gone.

Someone with a bit more tuning specific knowledge should be able to help. Its all tuned correctly by the guy who built the motor. Its all thru an EMS Stinger. He wants me to run a different higher octane fuel to stop the pinging & up the power. Thanks for the replies.

Is this car a daily driver/did your engine builder/tuner know it was to be a daily or is it only a circuit car? If you ran race fuel you would probably see better results but this isnt exactly practical if it's a daily.
And i'm with fordfairmont, even in my old race car we left the compression at a touch over 10:1 (although it was only junior street's)

Yeah he knew what i was using the car for. The fuel im gonna use is pump fuel but only available at 2 servos here in SA. One being near my home. So its semi practical. Like i said about the comp, its close to 11:1. Think it was 10:9 maybe? Cant remember.

If it is pinging and you have an EMS, get it retuned and take some timing out. That will solve that problem straight away. You may lose some torque, but it wont be that noticeable.

186rwkw @ 6800rpm. from memory 415nm.
Best 60ft is 1.901 Has run a 13.78 @ 104mph, 13.86 @ 102mph, 13.88 @ 104mph. AU XR6 HP motor. -Custom extractors -3inch highflow X-force cat -Custom 3inch mandrel bent exhaust -custom 3inch mandrel bent intake -Pod filter -Big a** billet Surecam -Vernier gear -Completely built head, spings/valves/porting etc etc Been done twice now. -Ported BBM manifold (got done with the head) -Aftermarket coil packs, Splitfire leads -high vol oil pump -walbro intank fuel pump, upped fuel pressure -Atomic Stud girdle -T5z Spec gearbox, because stock T5's are poo. -5 puck brass button clutch -2200lb pressure plate -Lightened billet alloy flywheel -Rebuilt 4.11 LSD diff with 80lb springs -SCT Flasher with Custom tune, 7200rpm rev limit. Already grenaded a stock bottom end at 7200rpm. Needs a new one, which I may be building soon, Undecided if I want to go further with it. Have also thought about the 6 x t/b set up brockyb has. These things have plenty of potential if you know what your doing with them.

Must be screaming its nuts off Can't really describe the sound, just one of those things you have to be there to hear. From 4500-7200rpm its just a type of sound you've never heard before, doesnt sound like any other 6. Makes me smile everytime I spin it past 6500rpm, but its like pulling a pin on a grenade. The whistle/induction noise, and a 3inch exhaust up at those revs sounds pretty nuts, it makes everyone look, makes babies cry and strikes fear into the hearts of most motorists. Garenteed to give you a funny lump in your pants and cream if you listen for too long. But basically yeah its screaming its nuts off lol. Im being nice to it at the moment, rarely going over 6000rpm until I sort out the bottom end.
