What's been the highest redline in a modded Maxima engine?

 

dude, think about about it...red line is what ever you can get it to once you have no rev limiter. but after you try this, you will probably have no engine.

 

Seriously... Redline??? It never changes. If it redlines at a certain RPM then thats where it redlines. Say 6800... If you mean where does the rev/ limiter stop then thats a diff. story all together. your car will always redline at 6800 but the rev limiter can be moved to whatever. I have heard of the infamous jerryrig here on Max.org by cutting some wires or whatever. I would opt to take the REAL route and get a programmed ECU. HMM, thats just me though...

 

Let me re-word this. What would be the safest rpm (no rev limiter) once you beef up the internals?

 

i'm not going to even bother with a detail explanation of this. the VQ30 motor doesn't make optimum power beyond like 5800 rpms or something close. so any higher, modded or otherwise, probably wouldnt be that beneficial.

 

I was just curious cause i'm planning on doing stuff like twin turbo (i'm not going to do the rest of the list cause i'll get more crap for it) and i wanted to see how high i could go rpm wise so i could stay well in the boost.

 

isn't redline mostly protecting the teperature of your gears, which does not have much to do with our mods.

 

Someone has a lot of money if he plans on twin-turboing the Max. I've had my Max to about 7200 RPM. That's with a Jim Wolf ECU mod. But honestly...keep it under the redline. If you want it higher you'll have to get new cams and basically an entire engine rebuild. (LOTS of money). And the best turbo boost is usually at around 5-6 RPM anyway.

Ok, thanks.

 

 

Twin Turbo? You are kidding me right? Don't tell me you going to mount one T4 on the front manifold and T4 in rear manifold. Maybe if cut up the firewall and not have a center consol. Anyway...It's feasible. Good luck and show some pictures when you are done with the twin turbo.

 

heheh, time will tell.

anyways, my motor supposely can handle revs to 8500rpm. the biggest prob at high revs is valve float, once you do it most likely you damaged something. think about lighter internals, stiffer valve springs and cams if you want to enjoy 8k+ revs safetly.

 

Ok lets think about this since everyone knows so much about engines on here. REDLINE is a simple concept. I shall speak slow and clear so all that are mentally impaired or new to motors may under stand. When a motor has been put together by you or some factory you dino the motor. When you dino the motor you will find that the motor has what we call a power band. That means it make optimal HP through out a certain RPM range. The end of this range is where your REDLINE comes into to play. Since there is no added HP at the end of the band your motor is doing nothing but killing itself. So what you do is mark your redline be it what ever it is. All motors have different REDLINES even those stock from the factory. So in regards to the initial questions build it, dino it, set it and have fun.

 

Wrong. And what's "dino"? Some Flintstones engine hp measuring machine? hehe.

Redline has no direct relation to where the powerband is.

 

u sure do have a lot of money for only being 17

 

I'm hypothetically speaking on this stuff. I will try getting a personal loan thing and pay off over some years to get my stuff.

 

i see, well i guess u could do that but u gotta build up some credit first before ur gonna get a good loan, hard to get approved for a loan being young with no credit, be careful too man cuz i have a lot of friends in trouble with debt and bad credit, trust me u dont want those problems

 

Its in inside joke jeff next time be a part of it... Also go to school some time they might teach you a thing or 2. Oh but wait I bet your some ASE guy I am sorry I dont know anything I am talking about. I have only been building motors since I was like 11. So p[lease in all of your mighty wisdom correct me. Explain to me what happens at redline and what the engines power band is... We are all waiting.

 

Can we say.... Maxima T T ?

 

What happens at Redline. Nothing. Becuase the maker sets redline BELOW the rpm where damage will occur.

What the powerband is wasn't part of the original question.

Now tell me where I'm wrong.

Now tell me what the powerband has to do w/ the maker's preset redline value??

I know it was part of an inside joke. I was in on it last week. Where were you?

I'm still waiting for the "dino" defination.

So how old are you now? 12?

 

Sorry didnt mean to come off rude to you jeff but for a minute there I thought that I was actually going to have to argue with some one. Yes your are correct. The Redline is set at the max RPM that an engine can safely run at before any number of damaging actions may occur. Why I put the powerband issue into to play is that if you look at an engines powerband and compare it to the redline, the red line is usually set around 500 to 1000 rpms higher than max HP on the powerband. When I build motors I put into the equation driver reflex and error. When you build 1/4 setups of over 1000hp and tons of cash you dont take chances you dont have to. Most drivers out of habit wait till redline to shift, which is a no no. By placing the red line at the end of the powerband you are making a safety margin. There go if you set red at 5500 when it is actually 6000, in the text book, in that split second it take you to press the clutch and slam it into gear you reach text book redline. This is of course if you really race your car. Some people actually take there foot of the gas when they shift. I for one am not, well while I am racing anyways.

 

I understand where you are coming from. Glad to have you aboard man.

Any particular reason you name is Turbomax95? Got a surprise for us? hehe

 

As a mater of fact I have been inspired for a long time to turbo my max. I have to find some pics to put up on here that is going to make some people mad. I moved up this way bout 6 years ago but before then I lived in Ocala, FL. Home of the first turbo maxima I ahve every seen not to mention only. And heres the kicker. It was dual T3/4 hybrids and for all those out there who think they are going to get 600hp out of a VQ good luck his was a 3rd gen with iron not aluminum and managed to crack his block on I-75 5racing a well moded NSX he spent over $45,000 on his motor and tranny to get a whole 450hp so those out there who think they are going to get 600hp putta the vq and spend only like $25,000... well yeah... Sorry ranting on a thred I read earlier that was closed. But any who I am in the process of building a motor for my TO4E I told the guy helping me I wanted to run a spool stage and top end stage nos setup with it... He turned white as a ghost and said "Man your trying to blow sh** up! But after you kill yourself can I have your stuff" I laughed and said must go faster!

 

Hey deezo I dont know how to take your post but I do have a really cute PIC of me covered head to toe in grease helping my father put together a 750hp supercharged 350 in our "Shade Tree" shop. Its really cute it shows me putting in connecting rods.

 

Hold the bus! Dual T3T4's? You gonna have to post some pics up in here partna.

 

I will startr looking today I dont know where they are of hand. From all the moving but it was a cool car but a pain to put together from lack of space. each turbo was mounted on a conecting c bracket and over set the hood like 4". He had to put this funk hood scoop on that we all ragged on him about. It was like a 7" pro stock scoop. Totally f-ugly but it was cool when he raced it he could almost get the turbos glowing red hot, gave the vents on the scoop a cool look at night

 

Uh..ok..

 

You need to empty your inbox jeff I am trying to send you a PM

 

Turbo, post a pic. I used to help my pops when I was that young too. Matter of fact I remember changing the radiator in his 1966 Impala when I was 11.

 

Try again

 

I'll do that. Cool to see we all can get along here. I am not one for just posting BS all it does is waste time and energy typing. But at the same time I can understand where you are coming from deezo there are way tomany many kids with way to much free time on their hands on here

 

And I thought you were another one. Welcome to the Org.

Man I have to stop prejuding

 

home of the only turbo maxima? interesting.......

 

Hey something just poped into my head while I was going over some specs... Has anyone checked the weight diff. of the sarona body kit with the stock weight?

 

Well this was before yours and uncle max's. BTW have you got it running yet... No pund intended Last time we talked you were still having the prob with the rev limiting.

 

i was thinking the same thing

 

My parents would help me once i get a job.

 

You have some nerve being new on here and insulting people. I've been employed in the automotive field for over ten years. I've built more engines than you've had birthdays and I can tell that the people on this forum are very Knowledgeable. Some join knowing little about cars with the expectation of learning something, thats no reason to talk **** about them! If you know so much and we're so inept, why don't you just try another forum where everyone is as smart as you. And you can take mtcookson with you cause he seems to know it all too. You are very arrogant people who have nothing to gain or contribute here.

 

And we an see maximus that your intelligence has been left some where else. If your really read the post, you might figure out that it was posted in regards to those claiming they know everything re: mentals and to help those who don't. So if you really want to pick a fight why dont you go some where else. And dont compare me to cook since if I remember right I was reading a post by him "I think" and thats what the rant about a 600hp vq came from. So why dont you just lay off

 

Your the one picking a fight pal. You did say "since EVERYONE knows so much" didn't you? If your refering to one person then just say that don't make a generalization. Everone on this board is respects one another so if you going to insult people expect some feedback.
