With this setup:
JDM b18C-R Head
Rocket Motorsports M22 Cams
RM Springs and Retainers

How far can i rev up to. what is safe for me to go up to and will give me good power. Basically what should i shift at. thanx

 

 

its gonna depend on what bottem end and what compression you are running.

I would guess the cams will peak around 8,000 maybe a tad higher. The best bet is to dyno it and see where power falls off after its tuned! Tuned being the key word here.

 

he has aftermarket cams in a ITR motor, not only that it has incredible R/S ratio, if the bearings are stock then i wouldnt take it past 9 if i was you, but yes a dyno and tuning is going to show you were power will stop being made which i will say is probably gonna be around 8500-8750 with an ITR and a good set of cams

 

i am running the stock 11:1 compression. i read that the stock cams run up to 8600 or so and your saying that the RM cams only go to 8000. so your saying these cams are no good and wont help?

thanx, are these cams any good then. will they help out my horsepower quite a bit or not. i am looking for a good set of cams and valvetrain for kind of a long run situation and thought these were pretty good

 

ive never heard of them, the only reason im saying not to much past 9 isnt the head, sounds well built to me if you can get it to flow, but more like the bottom end, not being forged and being on stock bearings id be nervous to go to high, plus anything past 9 the head if gonna need a good flow and you are gonna sacrifice low end big time at that point also

 

yeah alright i hear ya now. thats what i thoughtin the first place just had to make sure. ill just basically check how it runs at certain rpms and shift around 8800 or something.

 

IMO, you should also replace the stock rod bolts with some ARP's

i used to rev up to 9000 rpm on a dialy bases on stock rod bolts, but then they gave up at 7000rpm and destroyed my head by launching the piston into the valves

 

good point, head bolts isnt a bad idea either

 

thanx guys i should prolly get some head bolts too. their not that much more

Yeah you should also replace those

AEBS make good head studs which you don't need to heat cycle
and get ARP for rod bolts

i was thinking the same thing?

 

ACL or Clevite

i know people running stock bearings but if i was running a 4-5grand motor i wouldnt take any chances if i planned to rev 9grand daily thats why i adviced it

 

i was under the impression that oem bearings were as good as anything on the market.

 

Im running a "4,000-5,000 dollar motor" if thats what u wanna call it and i wouldnt out the ACLS in if u gave em to me free. That is just a matter of my opinion though, i know people who have had luck with both. Dont know about longevity on acls.

 

Why didnt you just make more research before getting the cams. You should talk to Rocket those are his cams , and from dynos i have seen , they make HP way past 8k, AznFlava i think was his' sn was taking them to past 9k rpms and it made power up that high.

check out http://m24x.com
or contact Rocket ,
not just ask a bunch of peeps that know nothing of the product.

 

to get the head to breath past 9 you are going to lose most all streetability

 

making good power past 8.5k rpms requires a properly ported from places such as RLZ, DonF, or Rocket Motorsports.

You'll also need header and Intake manifold.

Thank you for conisdering our products.
