6400 RPM ok for stock engine.

[Roland69]

Thismorning on my way to work I went to pass a car cause my friend was right on my bumper just looking like he wanted to see if I could get away from him (he was playing with me right on my bumper) so I pushed it up into 3rd and punched it. I took it up pretty far and it pulled away like a MOFO then slammed 4th and held it for a while then 5th....looked back and he was a air freshener in my rearview mirror. He had a huge grinn on his face once I slowed down back to highway speed's and he caught up. I hit the RPM memory recall and it went up to 6400 . I have never hit that high before...well not like that but I am sure I bounced of the rev limmeter a couple times doing a burnout. But I did pull away from him no problem at all

I thought it was kinda wierd because it pulled awsome right up till I shifted to 4th and sounded healthy no valve float or rattles or nothing. is this bad or is it ok to run my engine like this time to time

Stock rev limiter is 6250.....

 

[Roland69]

the recall says 6400

tach is pr0bably 0ff a little. i have buddies that claim that they have turned a st0ck 302 with a st0ck c0mputer t0 7500 but it d0esnt happen. at that high 0f rpm its n0t unc0mm0n f0r a tach t0 be 0ff a little

 

[Roland69]

it's wierd cause the tach was working great up untill yesterday then I pluged it back in today and it seems to work fine. My stock tach was out a little once the rpm's got a little highre....like 2500+

dude.... buy a new keyboard

 

[ls1beater4eva]

what is wrong with his keyboard its not hurting anybody his problem. 0 o there both circles. and btw i have seen motor that wasnt stock, but a stock comp go past 6250 actually ive seen them go to about 7500.mine comp had pulled up to that and my bodys 95cobra has gone just as high allso a friends 95 gts has seen about 6800

High RPM on a stock engine

From what ive been told by everyone in my family. If it is a stock motor and it will go that high. It can handle it. Unless something is wrong with it then it should do fine... I had a 92 and it had a stock HO motor with the timing advanced and a h pipe and flowmasters and anytime I drove it I couldnt keep my foot off the floor I never had a problem with it the 80k miles I drove it. But im a maintinance freak. I like to try and bury the tach. I figure if I break it I need to get a stronger one. Im mean to my motors though...

The only way I think you can get much past a rev limiter is to downshift into the wrong gear. Otherwise Im pretty sure you would have noticed the car nose over. My car pulls hard for a stock cam, and anything over 5700-5800 its done making power and falls on its face. If I were some of the guys out there I would hope your rev limiters work better than that. 7500 RPM is not good for a T5 to try to go into gear, or the motor to go with stock valve springs and such!

 

[Roland69]

it usually stops pulling at 5800 but this time it felt like it was pulling verry well. I didn't even notice that it got up to 6400K till I hit recall. Maby it's the calm before the storm lol

 

[25thmustang]

My guess is something in the recall is off. We found out my dads aftermarket tach was off a few hundred RPM. Personally if the car was still pulling your memory sounds off... its a mechanical thing, there is no way one day it will just continue to make power at 6400 RPM, when normally it stops at 5800 RPM. Either way, just sounds like a fluke to me, not something that will be happening regularly, if it ever did hit 6400 RPM.

Your family told you?...anyways
Roland....during my dyno session we found my stock AND autometer sport comp tach were reading incorrect..in fact my '950'rpm idle was infact 675. If you watch the power curve of a stock head/cam 5.0 you'll see the power and torque nose dive after 46-4800...it will still pull, but your not making anywhere near the power you would if you were to upshift.
