If you redline on fourth gear, is there any problems that you might have with your engine? For example, lets just say you are on the freeway and you are cruising at 80 mph, and you downshift to fourth. So basically you are on vtec all the way to 8K rpm on fourth gear. I know that puts lots of strain on the engine, but is it okay to do it once in awhile?

 

man I do it ALL the time....I live in VTEC......hahahahah

 

hahahah....but still....is there any damages to the engine?

 

It's the same as hitting redline in any other gear, engine speed is engine speed man.
Redline =

 

Honda's are high revving to begin with... My thoughts are, if you're car is built to handle the stress, by all means go for it. In my D-Series, I don't go above 7500 rpm in any gear (That's about 500 or so past redline). Just be aware of the repair bills... Overall, Honda's can take a little redline with no problem.. Moderation is the key. Just don't tach out!

 

They didn't put that red area in the tach for no reason. stay below that and you will be fine. As long as it's not from light to light, like how I see some kids driving, they're just asking for problems.

 

damn.......i am asking for them......

 

I'm was one of those kids, too. Every stop light and ~120 time slips from the track over the course of over a year. Hell, I made it a point to redline the b16...I would even downshift periodically when cruising on the highway. I don't believe that with the newer engines, especially Honda ones, moderation is key. It's all about going all out.

They seriously design those things to take it. Let me give you an example:

When I worked for Borg Warner, they had an S2000 engine on a dyno for 25 hours straight at 8500rpms. I guess Honda told them that they should watch out at around 350 hours, because a rocker or something will finally fatigue and break.

I lost my b16 and crx to an accident some months ago. It sucked, but I'll give myself this: at no point did I have any regrets about not making the most use of that engine. Don't short-change yourself. Just make sure you maintain the engine and warm it up properly before redlining. After that, it's all within it's design limitations.

 

i drive my b18c to the redline regularly in all gears except 5th, but dont go as far as fuel cut off/rev limit, hasnt done any harm so far!

 

8500 in 4th gear on my Z6, you do the math..........

It was 2 years ago, and chemical assist was involved.

 

i down shift to 3rd at 80 but 2nd will bring you up to about 60. got to love high revs
