Ams Evo Cam Test

Those are DSM cams.

The EVO cams that are 1,2,3s are just Comps standard grinds. Then the 4R and 5R are custom spec cams FP designed but still manufactured by Comp. The Xs were only for the older style 4g63.

HOW about some cossie M2 they would be suitable for this car setup>>>

I really appreciate the effort here, but I was wondering if you have any plans to do testing with an IX? Maybe just with some of the top performers here. I would be pleased just to see the results from the kelfords, a gsc cam, and an fp cam. Thanks again for the work.

HOW about reading the thread?

THIS TEST IS OVER AND DONE WITH.

IF YOUR FAVORITE CAMS ARE NOT ON HERE, YOU WILL NEED TO TEST THEM YOURSELF.

First off, I'd like to say that tests like this is what makes me appreciate the EVO community. Such extensive tests take time, effort, and not to mention dedication. To the crew of AMS (Martin specifically), I for one appreciate the hard work and it is going to serve as a valueable source for my next cam upgrade. Secondly, as I read through nearly 500 posts, I had to shake my head at the ungratefulness displayed by some evoM members with the repeated "what about this cam", "what about that cam" remarks. There are hundreds of cams on the market and the ones tested should give everyone in the EVO community an awesome baseline for choosing the correct cams for their own individual set up. It amazes me that the majority of people want everything at their disposal without doing a little research themselves. By reading through the several write-ups in "Turbo" magazine along with the knowledge contained in this thread, anyone should be able to make an informed decision as it relates to buying the proper camshaft combination. I personally learned quite a bit reading through this thread. I never would have taken into consideration the recommended threshold for a stock head (10.5mm lift) when comparing cams. From what I am able to gather, here is how I see things as it relates to my current/future set up. I plan on running a stock/E85 set up for the near term and ultimately go with a FP Red/E85 set up.

* upgrading from HKS 272 to HKS 280 gained around 20whp more with an increase of spool of about 150RPM
* GSC S2/S3 are recommended to be run with upgraded springs/retainers
* FP5R, GSC S3, Crane, and Tomei 280s are nearly the same overall
* GSC S2 and FP4R are nearly the same
* GSC S2 outperformed all tested cams (except Tomei 280s) between 5-7000RPM
* Kelford 272 has a 11.5mm lift
* JUN 272/272 = 225 intake and 226 exhaust; HKS 272/272 = 208 intake and 206 exhaust; GSC S2 = 217 intake and 217 exhaust
* JUN built around stock head flow rates
* BF272 (not tested) is nearly the same as JUN 272
* BC cams suck on stock head
* FP4R competed with Cosi M2 cams (not tested)
* FP4R has stock-like spool with better topend than HKS 272

So, with all of that said, as it relates to my current set and how I use my car (street, autox, drag), my choices would be:
1. GSC S2
2. Kelford 272
3. JUN 272
4. FP4R

I really appreciate the time and effort that the AMS crew put into these tests and it has certainly helped me to make my next cam upgrade decision.

on this car yes, but remember that these cams arent designed to be run on a GT35, so the results may be different with a GT42 for example.

Kelford 272's have 11.0 mm lift, not 11.5... the 280's have a 11.5 mm lift.

Thanks for the added details and it's certainly information that will shed some light on my potential choices. I'm going to get springs/retainers regardless of the route I choose for an added piece of mind and without knowing the specifications on the BF272, my choices are JUN272 followed closely by the GSC S2. I'm not willing to try anything above the 10.5mm lift range.

[EVOLVEU]

For the price, GSC S2s cant be beat!

[Mellon Tuning]

I'd like to know the specs on the BF272 as well but I take comfort in the fact that the fast BR built cars run them.

[wrceuro]

Guys I don't know to much about cams and all this lift stuff. I am running HKS 272/272 on my car and I wanted to upgrade to FP red. Which cams would you guys recommend for the street and drag strip.

Except they require a valve spring upgrade.

[Zeus]

All you need it is the inexpensive FP or GSC springs for OE retainers... for most of the cams here that require an upgrade.

I planned on upgrading springs/retainers for the added piece of mind. Zeus, it looks like I'll have to wait on the install as Uncle Sam is sending me to train until early October.
