Cosworth IX Cams RULE ! My test
edit - i'm sorry, did not look at the dyno's
There is no valvetrain work done except for the drop in of the cams and every mod to the car is listed on page 1, nothing was missed.

^^.. If you go to the first page of this thread, you will see that Al posted the third graph of IX with bolt-on mods for reference. My question was directed toward Stage II IX's graph, not yours.

Thanks for sharing good info about Cosworth IX cams. I am now convinced that these cams provide good gains of 20~30 tq/hp. One observation, why does the hp curve start to drop off at 5500 rpm on the last graph with Stage II IX? Shouldn't it at least continue to go up until 6500 rpms?

I do not recall the specifics of that tune, I believe he may have had ecu controlled boost which does not hold the boost as well as a MBC or EBC - I will have to go back and look over the dyno notes and his boost log when I have a chance
So do you really think GSC cams are crap, or you just saying that because, well i am sure you know why.

But, since my Buschur engine has been holding up really well and its hard to take apart a really great running engine for no reason
The Cosworth head is just a spare part at this point
I have a fully built bottom end over at Buschur's ready to go thatr has been sitting there for who knows how long as well as a spare transmission over at Shep racing
Since the Cosworth head is a nice size to have sitting on my desk that is my conversation piece at this time

The JUN 272 I use are a more high rpms drag cam that is on the very agressive side
this thread was meant to be dedicated for the IX cams...
i could be blind but i see more questoins and answers about the 8 cams than i do about the IX's. lol
freakin hijackers

Al - If you can find a nice cat-back & test pipe or high flow cat before new years, I will drive down and we will find out what the cams make over the stock IX with exhaust vs. no cams using the right spark plugs.
