but the car runs hard. decent weight reduction too.
What he said. I know that the springs on the Gen 2 coyotes are updated (possibly Boss 302 springs from things I have heard) and should be able to handle a higher RPM range, I just don't think it would be a safe option if you are really going to be pushing the engine. I went with the Trickflow springs on my engine as well and have been told that the engine should be capable of 9000 RPM if I ever wanted to move to a stand alone and go for that RPM figure just for whatever reason. If I were to do it again I would ask Eric about the PAC springs that they offer since I mean they are PAC and they make one of the best springs on the market and see how they would compare to the Trickflow springs.The stock valve springs are not designed for 8000 rpm pulls, you will get valve float. better safe than sorry. Yeah, it costs more but its great insurance to upgrade to a set of trickflows!!!

I would look into some custom grind cams for your build as well. I mean off the shelf is nice if you are impatient, but I would really look into something that is ground to the specifications of your setup and what you would like to achieve. They cost no more than what a set of Stage 3 cams are and should make some more power. My RGR/JPC custom grind cams I knew just by looking at the specs would make more power than the off the shelf comp stage 3 and I am thoroughly impressed by them. If you are shooting for E85 I would go ahead and also look into an E85 tune since there really is nothing you have to do in order to switch over to E85 even if it is a hero run, it will just get you that much closer and it is cheap HP in the grand scheme of things.
Stage 3 cams like i got require the stiffer springs! Most guys dont have stage 3 cams! So the stock /boss springs should suffice!If your not experiencing valve float just remember that stiffer springs also rob a little power from being harder to compress. If your not FI or revving to 8500-9000 rpm I'm not sure if valve springs are needed for a 500whp build. It isn't very expensive insurance against valve float for the parts, but the labor to replace all 32 (or pita) can add quite a bit for both. If it is proven to need them for 8000rpm and 500whp then I am all in, if not I am gonna take my chances with my stock Boss springs.
Say what?! Comp cams stage 3 NA cams are NSR! take a guess what NSR means!!Stage 3 cams like i got require the stiffer springs! Most guys dont have stage 3 cams! So the stock /boss springs should suffice!
lol that is the exact same page i copied the info from.....:frusty::headbonk:I dont have 2011-2014 nsr springs, I've got the newer more aggressive cr springs designed for the 15-17 coyote motor!!
