late friday nite around 5 am, i ran a b16 crx, and i miss shifted 2nd and accidently revved to 9300 rpm (my tach needle went way past nine)... it runs fine...im hoping i didnt **** anything up since my valvetrain is still stock... yea i'm stupid.

 

I took mine to 9 once. Nothing really happened. I destroyed my tranny, but that's about it.

 

went to 9191rpm on my K20A2 and blew 2 cylinders and bent two valves.

 

ouch

 

 

 

aint gonna do anything i revved mine to 9000 all the time

 

<---hit 8717 peak RPM as indicated on his VAFC last night. stock redline in my 2000 ITR.

 

nice intelligent statment.

dont listen to him.

if its running ok i wouldnt worry, but if you are do a compression test.

 

Yeh very nice isn't I even said "aint". Well I was in a hurry, but realistically it probaly wont harm the engine, I myself and other loacl guys I know rev B18's and B16's like that with no more than average long-term wear. I have seen and heard of just as many stock b16'a blowing up at 8200 as I have at 9K. My friend just got rid of his "bone-stock" b20/vtec car, Him, I and others revved it too 8.5K with no damage for 15K miles, if it's gonna break it'll break, if not...

 

lets say you arent gonna damage the motor
WHY are you revving that high?
have you upgraded the cams/valvetrain?
its pointless to go much higher than the stock revlimit because it dosent make power unless you have dont head upgrades.

 

i went to 8000 grand on my D16
I almost stained my undiees

 

 

i hit 8200rpm all the time... over raevving once should not do any harm to ur engine... just my thoughts...

i would have if i brought it to "eight thousand Grand"

 

I guess as long as you don't downshifted from over 100mph in 5th gear down to 2nd ,like this guy did.
He took pictures of his motor after

I remember reading that post when that guy posted it, never got to see the pics till now and might i add

 

actually two friends made the same mistake.
one - busted his clutch into a million pieces.
another one - bent his valves.

 

I've gone up to 10k with my b18c1 on a chipped P28. No damage so far.

 

i was in 3rd gear at redline and tried to go into 4th but it went into second..loudest noise i have ever heard. the tach needle on the gauges was below 10 and the needle on the auto meter was bouncing off the metal piece where you chage your settings...motor ran fine after that..did a compression check at school and it was still good...i for sure thought i fucked something up..BTW that was in my moms R

 

my friend did that in his si...bent his valves

 

well i guess i got really lucky then...

 

I took my old d16z6 to 8200-8400 like 10 times a day for 60,000 miles. Stock bottom end, stock head with only i/h/e, gude cam, and ecu.

My friends b20/vtec/turbo pulls hard alll the way to 9200rpms...add 10psi (or more) of boost on that and its like (HOLY $#@$$ HOLD ON) haha soooo awesome. Riding in the car ur like....daammnn shiiifftttt wwhoooaaaaa hooollddd on!! hahah -- its cool after a hard pull like that looking at the apex afc which shows a peak of like 9158rpms or something crazy like that.

liam

 

I've never gone over 8000 with my b20vtec, I'm scared to...
