This is the last time im gona post about this... I looked at my boost gauge and it went to 23.5 AS THE HIGHEST in my gauge and dropped to 21-20... AGAIN i am NOT spiking 25-26.. Damn i wish i had a logger so i can post it and stop this argument

DUDE!!! The spike is not happening because you are never at 3-5000 rpms in 4th gear at the track. They are saying that IF you shifted into 4th and started 4th at 2000rpms, then when you passed 4000rpms you'd be at 25-26psi, then by 5500rpms (where you actually come into 4th after shifting out of 3rd) you'd have tapered to 22-23psi, which is what you see because that's where you come into 4th gear.

They are saying that IF YOU RAN ALL THE WAY THROUGH 4th gear, you'd see that peak, but since you're only seeing 5000-7500rpms in 4th gear, you see 23.5psi WHICH IS AFTER the taper has (or would theoretically) happened.

They are not saying that you actually see 26psi, but that if you were to start 4th gear at 2000 rpms it would look something like this:

2000rpms: 0psi
3000rpms: 15psi
4000rpms: 26psi
5000rpms: 23psi (starting to taper, this is where you come in and your logging starts)
6000rpms: 21psi
7000rpms: 20psi

you come into the equation at 5000 rpms. But for your boost to be at 23.5 at 5000(or whatever) RPMs, it would have to be 26psi at 4000, but you don't see that number because you don't even see 4000 rpms. You're starting 4th gear at 5000....

They are saying that whatever you have your boost controller set at, if you were to drive it at 4000rpms, you'd be seeing 26psi. But you are only driving it at 5000+rpms, so you see the tapered value of 23.5psi

I've said it as many different ways (including the picture) as possible, hopefully you see.

THEY ARE NOT SAYING THAT YOU ARE BOOSTING 26, but that you would see 26 if you shifted lower based on the fact that you are seeing 23.5 @ higher rpms.

OH yeah... I forgot to say nice runs

lower 60' and you're in business!

Yes on the street if i left it that way, if i nailed it below 5k, it would spike 25-26 cause thats what happened when i went on the street after

Damn you guys had me confused LOL I see what you all are saying now
Took me a while til you broke it down for me, duh!!! HAHAHAHAHAHAHA!

exactly! So in a very confusing way, they were saying that your boost was set to peak at 26psi, but you didn't see it, because you weren't in peak boost range.

Your ACTUAL peak boost is what you said it was, but it was in limited circumstances (ie, @ track)

Thanks for clearing it up for me and thanks for the comments on the run

what a waste of time lol
good run.

true, but I have an OCD about trying to explain things! I can't leave the ends untied!

Ok, now that you know what we're talking about, 25-26psi is extremely high for 93oct. Why are you doing that? Sustaining 23.5psi in 4th is not wise unless you're on race gas. That's higher boost than when I ran my 12.000, becuase my gauge never read that high in 4th even on race gas.

You do realize that doing it on the track is no different than doing it on the street, right? It's extremely foolish to just randomly turn up your boost at the track because you THINK your boost is lower. I can't believe it took 30 posts for you to realize that you never see your true peak boost in 4th on the track and that you are running your turbo at race gas levels while on pump gas. Very poor judgement indeed...

whats so hard to understand about saying much boost your running. if someone tells me they're running 23.5psi at the track I don't subtract psi for taper, holy crap, I wish I had those precious minutes back I wasted reading all this garbage.

op, nice times and driving. were you spinning or bogging on the launch?
you're just a good 60' away from a very low 12!

Because when I go to the track, I don't claim whatever boost I see in 4th, because that is not the actual boost I'm running. Just because you only see XX boost at 5500rpm in 4th, it doesn't mean that's the boost you're running. If that were the case, then instead of saying I run 26psi daily on alky, I could just say I run 19psi, since that's how far down my boost tapers by 5500rpm at this altitude.

The fact is he is having to turn his boost up to 25-26psi in order to achieve these times that are so-so and that have been achieved by many others at 22psi. It is not smart for him to be running this much boost without adding some race gas, and if you know anything about Miguel, that is the last thing he should be doing to his Evo...

wow, that makes zero sense...

If 23.5 is the PEAK boost you are seeing, and someone asks you how much boost your running, why the hell would you say 25-26. only an idiot would make a statement like that.

to me it sounds like your jealious about his 'so-so' runs as you call it because he is almost as fast as you with less power mods. don't hate, if you have nothing positive to say then just sit back and stfu. it gets real old opening every thread and seeing you arguing with everyone like its you job.

wow warr.. people just dont fu*king understand... do they?

ppl r so damn ignorant lolol

*sigh* Some people simply _amaze_ me. Good God, man, how hard is it to understand that what you SEE from 5500-7000rpm is not the boost you're running? We have explained it TIME AND TIME AGAIN!! Just because you're never below 5500rpm, it doesn't magically mean your boost level is what you see at 5500rpm. Is it really that hard to understand? I mean REALLY...is is _THAT_ hard? What if he was never below 7000rpm, then would he say he's only running 20psi even though his boost is turned up to 26psi? Gimme a break, man, you're barking up the wrong tree here.

The fact is he went to the track with his boost already set to 23psi or so. He thought that the track magically made his boost lower, so he turned it up. This means his boost was now higher than 23psi. Just because he only WITNESSED 23.5psi while in 4th gear on the track ABOVE 5500RPM, that doesn't mean he was only running 23.5psi. Do you still not understand? He had his boost set to 25-26psi, and he would have SEEN 25-26psi had he been at peak boost RPMs of 3800 or so. He even said so after he figured out what we were saying - he said his boost WAS at 25-26psi peak after he drove on the street. Guess why? Because he hit peak boost rpms. His boost didn't change from the track - the only thing that changed was the RPM he was seeing. That means he was running 25-26psi on the track, too, regardless of what he saw on his gauge after shifting to 4th.

Why would I be jealous of him? I ran 12.26@110 on 93cot with LESS mods (no manifold or o2) than he has on his car right now, except I had a base flash, not a custom tune, and I was running 22psi PEAK (yea, at 3800rpm), which meant I was never above 20psi in any gear on the track. So yeah, might want to re-think that statement...
