I think it's good enough for 9000, yet it's hard to find cams that will make power that high with B16's compression.

 

yea, and a stock b18c1 handle?

 

it dosent matter if you can rev sky high. why would u want to is what you have to figure out. u should also get valvesprings and retainers. remember it is not just the bottom end that limits how high you can rev. a B16 will go to 9 all day with valvesprings and retainers. i wouldnt take a C1 without valvesprings and reatiners past 8500

 

I am asking how high a b18c1 could rev to w/ stock bottom end. Hypothetically the engine would have a built head.

 

There's one guy on here who say he's taken his stock bottom end to 10000. I've heard it's good up to 9500 and that's when the rod bolts start to stretch. I'd say 9k with a 9300 revlimit.

Edit: this is on a b16.

 

obviously i will be building up the top end,it is the bottom end that i would like to know the limits of,so what i am hearing is that 9000 is safe? correct?

 

10,500 is the highest I would take a stock b16a block..

 

i wouldnt take the c1 past 9

 

I wouldnt just build the top end...but that is just me

I do....9500 to be exact.

Neither would I, but show me some cams that are gonna make power at 10,500 RPM and I would be really surprised.

 

10,500?! heh i had my sotck bottom end to at least 11 if not 12. 10 at least once a week

 

i would think 9K max on a B16A block with stronger rod bolts like ARP.
i wonder how the stock rod, rod bolt and piston setup would hold out when seeing 9K rpm often. of course as was mentioned the cams would need to make power up there in order to make it worthwhile reving that high.

i was going to take my freshly built B16A (Eagle H-beams, ARP 2000 bolts and Arias pistons) up to 9K if i ever get the cams to make power up top. right now it's at about the stock redline with stock GSR cams. needs some odds and ends too.

 

lemme say this again. im running rockets valvesprings, and cams. thats the only mods internally, and ive taken it to 10 plenty of times. i freereved to 11-12 once. very scary but the motor is still in once piece, just burns a little oil

not bad, surprised it all held together.

 

i think, that the agressiveness of the cam will determin the rev limit. rod stretch sux, and since my cams are relativley small, i think thats what keeps hte valve from hitting.

rocket advertises the springs to 13,000 rpm. i am afriad to go that high

remembe sgt ran his fully built b18c to 11,000 rpm. it has a much worse R/S ratio

 

Stock B16 blocks will take 9K without any problems. Just make sure your valvetrain can handle the RPM's.

 

stock b16 bottom end, making power to 8800, redline @ 9300, hasnt blown up on me.....yet

 

i took my b16 to 10,000 twice a day. each time i got on the freeway.
stock b16a 1 series bottom end from an automatic.my cars peak power was at 9000 rpms and didnt drop off more then 5hp all the way till 10Grand.

 

this thread is a huge testament to the durability of the b16 motor! this is why i refuse to sell mine

 

Well, lets say they designed the rods for infinite life at 8000rpm with some safety factor. When designing for infinite fatigue life, the end result is usually something that operates at an alternating stress that's a fraction of it's tensile strength.

This means that the bottom end will handle 8500rpm, it will handle 9000rpm, and it will probably handle rotations in the five-digit figures as well. However, it will not do it forever. The higher you rev it, the sooner it will fail.

Keep in mind all that they did to a Type R motor for 400 extra rpm.

Exactly

 

The cams that would let the motor make revs at HIGH rpm aint gonna suit a motor at standard compression

holy fawk...
thats sport bike territory
what about built b16's then? b16b's? people must take those to the moon!
