I think we need a test between these and a set of GSC S3s.

 

I second this...Any insight Em with the 650s compared to S3s?

 

Honestly, I have never tested or used the GSC's. I have no real reason to test them as ours work very well and we have not found the end of them yet.

Just plain straight up ignored your question huh EvoDan? LOL! I want the answer to that question too.

nfo VS the br272 cam????? how much laggyer are these VS the br272 cam. i like my cams but if you and dave made some updates and that are acceptable then i want them. maybe a graph of each would be best???

 

Looks like I am going to have to get my car dyno results to see if I can upgrade to these. Sounds like something I would be interested in. I have the forced performance cams right now. I have heard I am estimated around that area.

 

I'll have results on these soon on my car vs Kelford 272's, I put down 657 on the Kelfords and .63 hotside HTA86. I swapped hotsides to the .82 but the car isn't waking up so could be the cams holding it back. They'll be going on very soon and then I'll be going back to the .63 to test that out with the cams also. Thank Tom at VR-Speed, he's a great tuner and is doing alot of this work on his own time to help out the community

 

Hey Em, I have been searching for some reviews on these cams has STM come up with any more comparisons? Any threads specifically that show reviews on these cams?

You should get these & their new small front brake kit...weight reduction!!

 

There brakes will do me no good on the street. I like them but there for 1320 only imo

 

Sorry, I do not have any real data to post with back to back runs on these cams VS anything. We have only had a few sets made and I am pretty sure every set has found a home in a 700 whp+ car. Basically, they work very well in the top end and if its spool you are looking for they are probably not the cam for you.

I would suggest them to anyone drag racing a 650 whp+ car that plans on staying over 6000 rpm's the whole way down the track.

I just picked up a set of the 650s from Emery a few weeks ago and this weekend went another 9.1@159.88MPH. Almost 4mph faster then the old Mivec head with also a slower 60ft time. Car has a 8 sec pass in her and going back this weekend Cams are awesome, im satisfied!

 

Thanks Joey! I am glad you are happy with them. If you have video of your car idling or racing feel free to post them here.

ill let you know but its going to have to wait till spring. im swapping my BF 272's for emerys cams

 

I have tested them, more top end power just like Emery says. I agree with Emery on the HP and RPM requirements to run them.
