E15et cam
E15et cam
Gooday all i read the spec sheet on the cam to see what i can get it shaved to, according to the sheet stage to is as high as you can go, this doesnt bother me thats what i want but after ringing around (adeladie based) nearly all the places say that the standered cam wont go that far and wont make much differance.
Now i would really like a stage two cam for oviuse reason most of it being that i love the sound these cars have with them lol
Please could anybody advise me of what i can do and if maby i calling idiots that dont what they are on about
Best regards et_rider

Funny. I have juuuussstt, swapped back to the stock cam after 5 years of putting up with 20% less poke down low for a smidge upstairs.
I'll have to see what the dyno shows.

I'd be interested to know that...
When i did the last engine change (the one that subsequently exploded) I notice a big difference in driveability with the "big cam" (what ever grind it was). And not that much more top end....be interesting to see.
One cam bloke in Adelaide told me years ago that to much overlap in a turbo cam would just see all the pressurised air blow straight out the exhaust... he suggest 'very mild' for better performance...

Often the cam isn't the limiting issue for higher revs. Often engine balance means more revs will cause more engine degradation or even straight failure. Similarly oil pumps often can't continue to supply sufficient oil to keep the moving bits seperated, cause damage to the likes of big ends etc...2fast2stop wrote:Does a stock cam allow engine to rev harder? (higher)
Cams are typically tuned to provide performance within the acceptable rev range, which is dictated by the other factors.

correct me if im wrong im still learning but id run a standard cam iv had mine grinded but i didnt do my research and talking to alot of people a standard cam would be just as good cause the idea or a turbo engine is to get as much air/fuel into the combustion chamber so by changing the cam it would close the valves sooner and open them sooner ect. as i said im no expert but please correct me if im wrong.
cheers

three things can be done with cam regrinds -
Change openning size (more is usually better fo get more air through)
Change opening times (more the time it opens, which changes valve timing)
Change duration of opening (change how long the valve stays open, longer is normally better to a point, and that 'point' is different for turbos and non turbos......which is what was discussed above)
