All this fighting...I would like to read something from this Justin fellow.

 

Whos fighting? The only thing i was "mad" about is eddy coming in here and giving people false information. The newbies that come here and that read this, they tend to take things to heart and i want to make sure all information on any thread i start is as accurate as possible. That way, future people that look on the thread can gather real information instead of false, or misleading information.

I too hope he comes on here, but people getting upset at me is pointless. Not my xb, not my times. Its not completely impossible giving what he told me. Its definitely a strong possible to hit 14's.

 

Check out scion.com click on pdf x/b specs it clearly states 103hp@6000rpm. I think last years was higher like 106 or 108. Iam not giving out any false information just calling out people who make wild claims about how fast someone's x/b is.Just tell Justin when he gets a chance to post some time slips and a video of the run and don't forget to point the video camera at the scoreboard so we can see the et and mph.

 

You are giving false information. Powerband reflects nothing on how a motor performs. Specific mods can change the powerband from 6,000rpm to higher or lower. Just because someone peaks whp at just say 4,500rpm, does not mean their motor is running rich, lean or poorly. It just means the powerband has changed and now they are peaking whp at a lower rpm compared to stock. It would be pointless for someone to peak whp above 6,000rpm given our redline is right at 6,350rpm. Unfortunately, we vvt-i does not offer the same performance level as vtec so you could have 120whp at 6,200rpm and still be slow as crap. Well, depending upon the climb of power between 4,500ish to redline.

Either way, this is false information when you imply powerband reflects performance of a built car. Not every build up is strictly top end.

 

Powerband does affect how a motor peforms. A street motor makes power from idle to 4500-6500rpm depending on the displacement. A race motor will make power from 3500-13000 rpm and a street strip motor from 2500-7500. I have never heard of any stock motor reving 900rpms higher than the same size engine with mods reving 900rpms less and making more hp. Even if you bored and stroked and motor it wouldn't lower your max power rpm by 900rpm. If you don't believe me talk to any person who builds engines for a living and tell him about this it makes no sense. Did you go to scion.com 103hp@6000rpm I was right huh.

 

Seriously, you either dont know how to put whats in your head into words or you honestly dont know anything. Im saying this nicely.

Your generalizations of how certain components in a car perform are probably the funniest thing Ive read on SL.com for awhile.

It is possible for a motor to make more power at a lower point in the RPM band in boosted applications.

Honestly, your generalizations are misleading and false for the most part. Stop being a bench racer and leave this thread.

 

BrianxB what Iam saying is when I added a s/c to my x/b my peak hp was @5900rpm and when it was stock it was @6000. My motor didn't lose 900rpm . I never said you can't make more power at a lower rpm with a boosted motor. What Iam saying is how do you add a s/c to the x/b motor and now it's peak hp is 900rpm lower. So you add a poweradder and lose 900rpm. Someone please explain to me how this works?

 

Tuning. Simple.

 

Adding or pulling timing out of the motor or changing the a/f mix is not going to make your motor peak 900rpms earlier. Tuning may change your peak rpm not that much. I think he cut the dyno run early at 5100 and shows his dyno print out to some kids at the local street drags or the track. Next he races them for some money hits the nitrous button and takes home some nice cash.

 

Tuning, just like Brian said. I admit, i'm young and still have much to learn however its obvious you know absolutely nothing. Yes, 103hp was right and i admit, i was wrong with that. I'm not "too much of a man" to admit when i'm wrong. Infact, thank you for correcting me. Now putting that aside, you are wrong on how the powerband effects performance my friend. End of story. Think what you want, but do not come in this thread giving information like this. Its false, misleading and i perfer keeping my threads i make as helpful and useful as possible to those that have less knowledge than myself or others. I have asked you nicely to leave, and i will ask you nicely again. Actually, you don't have to leave you this thread but i would perfer you to stop giving information like this. If you want to bring up your powerband theory, start your own thread to discuss it.

Oh, incase you are wondering what knowledge i have with motor build ups: n/a 97' gsr, 231whp @ 7,100rpm raised redline of 8,600rpm. low 13's 1/4 with custom gearing. I have also helped with f/i and other n/a builds on civics, integras, rsx-s, usdm tegra type-r, celica gt, helped a little on a 89' mustang project, motor swaps, re-builds.

It's possible with tuning and different mods to lower your powerband and make more power, just as its possible to increase your powerband and make more power. Same logic and process's for both. Only difference is, instead of tuning for top end you tune for more mid-low range.

 

Since you had no replies to your thread I thought I would get your thread going. You don't have to prove to me how much you know about cars since this isn't about you. Just have your friends buddy Justin get on scionlife post up time slips for 14.2 and lets see that dyno sheet. smiple right

 

relax.

 

Technically Eddy, you don't "lose" 900 rpm. (That's actually only 100 rpms lower btw) Those rpm's are still there, it's just that on boosted applications, more so on turbos, that after a certain point, the power adder just can not add any more power. So it begins to taper off. This in turn means you hit your peak horsepower LOWER in the rpms than you would on a N/A engine. Turbo systems are notorious for this, and some superchargers that I have dealt with do it too, just not as often since they run off the belts instead of exhaust. Hope this helps to clarify.

 

he should throw in some injectors and a fuel rail and maybe he could b faster cuzz i dont see fuel management stuff listed and what is he drivin a auto or manuel?

 

^^^The greddy supercharger comes with a pre-programmed e-manage, so there is some of the fuel management. But I do agree, he could defintely help himself out by adding a fuel rail and possibly bigger injectors, if he doesn't already have that is.

 

He has fuel rail and injectors on the way, the list i gave you is what he has currently. Maybe we will hear from him on the boards sometime this week or next. He said next time hes on, too bad he has a life unlike me otherwise he would have already posted.

 

haha to bad he stays like 40 min from da FL border if he stayed near ATLANTA i would ask for a race haha just for da fun of it

 

$173 speeding ticket on the way to work today will keep you from wanting to do ANY racing. Stupid blind curves... state tropper sitting on the inside shoulder... my own fault I guess. Anyone recomend a good radar detector?

 

haha i got a ticket for loitering cuzz me and some others were watchin ppl race and dat ticket cost me $140 so basically i got charged for standing around haha we went in like 20 ppl deep for the same ticket might as well b a speeding ticket cuzz it cost me $140 for goin 20 over

 

My Chevelle was not even at 300hp and ran low 13's...where is this generalization coming from?
