so, i've searched and read a few threads where guys have blown their motors doing low-rpm pulls in 4th or 5th gear. so my basic (noob) questions are:
1) i assume you can still accelerate in 4th and 5th gears, but how much throttle is considered "safe"? (i assume when people say "pull" they mean WOT)
2) at what RPM do you become safe (i.e. no longer considered "low-rpm")? or does this basically mean that everyone downshifts to 3rd to go WOT?

 

It is pretty easy to determine. If you're cruising and accelerate and hear a deep pitch kinda "hummmmm" you need to downshift. This goes for all cars, not just evos.

 

the manuel doesn't stae what gear you should be in every speed, but it states that anytime your under 20mph, u should be in 2nd gear and anytime you're around 20-30mph, you should be in 3rd. it doesn't go in more detail.

you shouldn't have to worry about blowing anything up. it can happen, but its not likely. just don't do it consistently.

 

You are in a mitsubishi, not a corvette. I went WOT on my evo from a dig to 120 without problems, and i didn't about 5 times that day. I didn't go past 6500 so that's probably why i didn't blow my motor. Just take it easy on the car.

 

A PROFESSIONAL tune, from a skilled and experienced tuner is the easiest way to not blow an engine up.

 

Completely agree. Just hope that doesn't open up a can of worms.

 

so low-rpm WOT pulls in 5th are ok on the stock tune in a car w/ no mods? or doing so is ok as long as the tune is good?

in other words, people who've blown motors at low-rpm in 4th or 5th do so because of a poor tune?

 

I'm not sure I understand this topic... I start my pulls usually from 3k rpm which is approx where the turbo starts to spool. I wouldn't exactly start going wot at lower rpm's since not much happens anyways.

But maybe you guys can enlighten me on how do you blow a motor on low rpm pulls...

 

When your engine is at a low rpm say 1200 rpms in 5th and you go WOT it's putting a huge load on your engine which in turn can blow it.

 

So when logging pulls for 3rd or 4th gears, what would be a "safe" RPM to start at?

 

Don't bounce off the rev limiter!

 

Ask your tuner. Base maps vary.

I completely agree with Kracka; the easier way to avoid a blown motor is to get a professional tune from an experienced tuner. Too, it's up to the individual to explain how he drives, his uses for the car and his expectations to the said tuner. "I want the most power," should rarely enter the conversation.

For example, my tuner knows full-well that I use my car rather enthusiastically and that I expect perfect performance anywhere and everywhere in the rev band. He knows that I hammer the thing in 5th, and he knows that I'm mostly concerned with having a reliable and drivable Evo. As such, the car was tuned somewhat conservatively. If I kept pushing him to make more power, such flexibility wouldn't exist with the assurance of durability.

 

Makes sense. Im on cobb stage 1 right now, so I can assume that was made to be fairly safe?

 

Bump!!!!!!!

 

I don't know. I have seen some discussion about Cobb maps on EXF. Might be worth a look.
