dewismotorsport Sounded tinny to the touch so decided to chop it in half, this was all that was left :eek: System was only a couple of years old
milo Mine sounded gr8 when carl installed it and the quality looked gr8 as well, but well before i got the charger fitted the the exhaust note changed noticeably under full chat it was a lot louder and sounded flat. What did your mates sound @[deleted]
evocarlos dewismotorsport said: At the end it sounded awful, like someone had fitted a dustbin for a tailpipe :wtf: that's what my current one sounds like at a guess i would say the center silencer has collapsed and due to the local branch closing i can't take it back for repair the cobra has the same lifetime warranty so if it drops it bottom it will go back for a repair 🙂 i cant find anywhere that can get me a 3" system made ready for fitting in the short time i have till mapping day cobra said 3days 4days ago lol
milo evocarlos said: 8th of june and 3" outward rolled Sweep stake again!! I got it bang on to the hp the last time u went on the rollers. So this time I'm going for 318.2hp @the clutch
Dave_Gilbert 327bhp at the clutch(u loose abit from there to the wheels dont you?) for the work done id want to see atleast 320bhp
milo Dave Gilbert said: 327bhp at the clutch(u loose abit from there to the wheels dont you?) for the work done id want to see atleast 320bhp CS say 20% on they rollers
milo Looked at everyones power runs when at CS and only carl got more at the clutch than me by 3hp :rolleyes: but torque was same
Dave_Gilbert So id expect the polish n porting to give 20hp, water pump/ balance delete 5hp cams 10/15hp New valves n springs might help not sure lets say 5hp so id say 45/50hp on mods over the 267 so thats very close to you estimate.

corsaZ22se you on 9:1cr now carl? that losses a few bhp but gains more reliability with more boost and bigger cams. you running the 2.8 pulley now or smaller? been out in mine over the weekend and I don't care its well under 300bhp it still goes well enough to make me smile and sounds great too 😃

Dave_Gilbert I want a dump valve. but gonna wait untill its running. Dont blow it up again, tske it steady
