EVO IX Cosworth Cam Dyno Results
It is what it is
I see a car which was done at TT in so cal that had the buschur 20G and the cams which made basically similar power on pump gas
The reality is that 350 to the wheels is about as much power as a IX will make on pump gas with the stock turbo
Adding some cams or other bolt on parts is not going to get the car to 400 whp on pump gas - IMHO
A better investment may be a alcohol injection kit but as you know that route has its pit falls and may fail
The new alcohol kits with built in fail safes - such as the Perrin are fairly fool proof
Personally, I like the way the cams "feel" on a IX and I would get them if I had a IX
The Cosworth have a nice idle and I just like them
To each his / her own !

I recently tuned some cosworth cams on an EVO ix and agree with those results. once you get past the TBE, mbc, and tune.. it is very hard to make power (i almost believed it to be impossible) on pump gas. The Cosworth cams are showing about a 15 whp increase to what I once thought to be the limit.
past 4000 rpm the cosworth cam'd EVO dominates my best tuned evo 9 w/o cams the entire power band by 15 whp.

AL i see great low end gains ,correct me if wrong, almost 70 hp at 3400 is that possable , i am thinking of getting the cams and evo green,also would his boost taper relate to his power drop off after5000 rpm?? thanks you tuned my red 9 last week at BR, i am thinking that the green and cos cams ,with my existing meth ill be a lot flatter up top, thanks again for doing a great job on my car, dean
The power is dropping due to the boost falling
I agree that the cams and meth would make the car have more power up top and give it more TQ as well
It is a nice good all around driving combination IMHO

There seem to be some who are making huge claims which I do not see.
In testing a good base line and post mod control are super important to reaching any conclusion.
The most important thing for customers to know is that just adding the cams without tuning will not give you any power. So far I have needed to make significant tuning changes to see any gains of any kind.
BTW - just to add
I have sold, installed and tuned 3 sets of the cosworth cams to date and every single one of those customers has been 100% satisfied and loved the purchase. I have not heard any negative feed back.
Al what sort of consesus have you reached regarding these cams being used on the stock valve train? Do you recommend upgrading the springs/retainers even at stock rev limit? It seems that the aggressive lift on these cams would cause premature wear on the valvetrain.
I agree... i don't have on the car testpipe, o2 housing, piping kit, fmic, ported manifold, or alky kit... when all these go on the car then i am pretty sure that we will see 400awhp on the Dyno Dynamics...
and don't forget on our race gas mix run, the bov opened thus dropping the boost pressure instantly. I think if we had adjusted the greddy bov to a stiffer setting the car would hold more boost throughout the power band thus making even more power...
Nevertheless, i am very happy with my car.
al, are you comfortable with the tuning of the cosworth cams to the point that you would offer some mivec changes in your mail in flash?
i'm also interested in the opinions on running stock valve strain on these cams as well.

I have been using stock valve train (lifters / rockers) on my race evo to 10,500 rpms with more lift
I need many more cars to tune before I can set a good patern
jk
until the summer probably i will have a whole bunch of extra parts on the car so i guess re-tuning will be necessary...
On mail in tunes - I must do 10 - 15 cars to develop a pattern which works consistantly before I relese a new tune application
I believe that after all the bolt-ons and testpipe i will be able to see more than 350awhp on the dyno dynamics...
