Cosworth or GSC
As far as I know, Dynoflash has only tested the Cosworth cams for the IX. He hasn't tested GSC's or Kelford, so how do you know the Cosworth's are that great? They may be the worst of them, you have nothing to compare them to. Al was impressed with them, comparing them to VIII cams, and because of MIVEC, it's not a good comparison. Food for thought..

Yeah I'm well aware of that. I was talking to the people that said they were getting Cosworth cams based on Al's (dynoflash) testing. I was saying Al hasnt tested any other pairs of IX cams, so take his review for what it's worth.

i kn0w one thing though...Greg From GSC is a great great guy to deal with..i wish i could take that into consideration to help me purschase cams from the car..but his personality has nothing to do with his product.
also remember that al will not give an honest review of gsc products.
anyways, there has been before and after comparisions for both these cams on this site. Search and figure out what suits you best.

I'm awaiting more test results for the GSC S1 cams. AMS is supposed to be testing them out soon.
I've not seen very good results from the original GSC IX cams or the Cosworth IX cams. Both netted about 10-20whp in most stg I/II applications. To me; not worth the install and tuning hassle for the price.

I'll jump in here with some info for you guys.
The GSC S1 Cams are designed for as stock turbo or small upgrade. These will defiantly out shin the S2 or Cosworth IX cams when used with a stock turbo. Better Spool, more bottom end tq and more gains under the curve. The S1 cams on a stock turbo will make your car faster than the S2 or Cosworth as far as daily driving and road racing/autocrossing. Drag racing might end up being S2 if someone is running supper high boost.
The S2 grind and the cosworth needs to be on a larger turbo. 35R 37 and probably some of the 3076 guys really pushing it.
When you make your cam choice for the 9 you need to make or have your turbo picked out or at least the power you’re shooting for. ie if your staying small 50 trim, 20G, 3076 or stock go with the S1 if you got plans to go to a 35R then you have a decision to make.
We are going to do a little test on a stock turbo with the S2 grinds to show the differences of S1 to S2 on a stock turbo. We should have this dyno to post in the first couple of weeks of jan

Seee....this is what i am talking about...first hand communication with the producer of the cams...but if i got the cosi..and had a problem..i would have a hard time to communicate with them...
therefore..my choice has been made..a set of S1's to set me right!!
greg ... prepare the cams...i am getting them.
Greg FTW

So for the case of the 35R between the S2 and cosworth which one out shines the other? I know your the a gsc rep but in your honest opinion based on testing from both cams. Haven't really seen any info for the cosi with a 35R....
I've never actually seen a cosworth cam. so i havent messured them. from what the specs that are posted they are close. our S2's have slightly more lift than the cosworths posted numbers. very small amount tho .2 on the intake .1 on the exhaust. depending on their design of the ramp and where they put the center line it could be a toss up. I would have to go with ours do to the increased lift and i know our ramp design is very good. but then again i havent tested them back to back. knowing what i know about the 4g head i would say if they are more agressive than ours they will put undo stress on some other head components, but i havent seen them yet so i really dont know.

I have tested Cosworth cams on a bone stock IX and it spooled up significantly faster and harder than with the stock cams (with proper tuning)
The Cosworth cams are really good with the stock turbo
My impression has always been that intended RPM range is the # 1 criteria for selecting cams.

BTW - for those interested we are dynoing a Stage II Evo IX (Stock Turbo) this evening - 93 octane and meth
With Cosworth cams
It previously made some 360 whp on our Dyno dynamics so it will be curious to see how the new cams effect the power band
We like to test things and show hard facts
