So i plan on buying cams for my evo 9. Its a stock block with fp black, bolt on, and a 450 pump. Was wondering if i can run cams without upgrading my valves and springs. Any suggestion on what cams i shoud get. trying to hit 450HP.

 

Run those S2's! (many of us do!) Must get the springs for sure! I would get the Ti retainers as well!

No need for any valve work.

 

Okay thanks bro.. I'll look into it.

 

The modest lope is very addicting

 

Hope to hit the 450s

 

Im running the S2's on stock internals & the FPHTA71 & tuned at 460 Dyno jet WHP

 

So just get the s2 cams and springs..

 

Yeah, The S2's w/the springs & Ti retainers

I assuming youve the fuel pump & injectors & the other supporting mods?

 

Not the injectors yet. Not really sure what size injector I should go yet

 

Yeah, im running small RC1000's & they are tapped out on my E85 tune

If im not mistaken, our engine Gurus, would suggest a min, such as the ID1300's

 

S2's and the appropriate spring/retainer is kit is a good choice, the GSC 5040 part number.

Are you trying make 450whp on pump gas or E85?

 

So just wondering if I can run cams without doing vavles and springs. If so what do you guys recommend me getting for cams? I got full bolt on n fp black with a stock block. 450 walbro pump. Trying to hit 450. So let me know what you guys think about the cams?

 

Based on limited info, You need bigger injectors and e85. Then 450 will be cake, even without cams. On pump gas, a mild cam will help. Maybe something not requiring springs. Hopefully someone can come in. Also, you would swap springs and maybe retainers. No need to change valves.

 

Yea for sure I'm going e85 n think about 1450 injectors.. but was just thinking about throwing in cams also

 

Why did you start another thread?
