i was just wondering if any one knows about how many rpms stock b16 rod bolts cah handle with out streching or braking?Also how many peaple have broken stock rod bolts?And what rpm were you running?

 

bump

 

I have a stock b16 bottom-end with a built head, i redline mine at 9200 right now, have been for about 10k miles. Higest rev the engine has seen is about 9800

 

I'm just bumping this up to get more heads in this thread.

 

The stock Honda rod bolts are very strong and should be able to handle any rpm you throw at them where your cams are still making power. ie: you won't be reving past the power peak of the cams so I wouldn't worry about the stock Honda rod bolts. ARP rod bolts realistically just aren't required in a Honda engine to be reliable at high rpm.

 

thanks for the info,no one out there has broken b16 rod bolts?

 

It's not uncommon to see 10 second Hondas and faster running stock rod and head bolts, stock bearings and stock piston rings, crankshaft and headgasket. Unlike a lot of OEM domestic parts, they are very high quality right from the factory.

 

B16 rod bolts are storng, johnzm on here was rev'ing his stock b16 bottomend to like 10k for awhile. Youll be safe at around 9k, 10k i really dont know about.If you feel unsure, just get the ARP bolts.

Then what causes them to break?

I have broken B16 rod bolts reving to 9200 rpms. I have also boken B18b rod bolts reving to 7200 rpms on bottle!

did you measure bolt stretch? there is a spec on that and if stretch is outta spec they will break. also were those motors ever rebuilt?


i revved my internally stock bottom end b16 to 10 a bunch and to 11-12 once. i have hit 9+ on it since fresh bearings... but the head is stock now so im worried about floating a valve..

this is stupid, i havent EVER seen a 10 second honda with a stock rod. not to say it isint strong, but come on, it takes 500whp to hit 10's!

 

all motor B series cars are making 500whp?

 

Where can i pick up one of those gauges to measure stretch?

No these were stock motors that were later modified but the bottom end was untouched!

If you re-read what I was saying you'll see I was actually saying rod bolt, but I'm sure it's possible to run that fast on stock rods.
