do yu think an xa with 14 lbs rims, a DC header, hyper ground system, hyper voltage system, and an AEM cold air intake will be able to take on an automatic nissan SE-R (non-specV)?

the SE-R belongs to a friend of mine. im hoping the light weight of the Xa would be the advange to make up for the lack of TQ and HP against the nissan.

 

I thought you were on a budget! lol

the SE-R is 170 HP, but weighs 3600lbs... I'd put my money on the SE-R, but I wouldn't be suprised (I'd be happy) if your xA won...

 

our little scions are peppy in the beginning cuz of the ultra short gears.
but once u hit 100.. u're done... i lost a few races cuz my car can't go faster than
120.

 

Hi this is my first post but I don't really have a chance to introduce myself. I've been lurking around in the forums for awhile because I am seriously going to be getting my xA sometime in the next two months. This seems to be a great forum with very nice and informative people (for the most part). But I just had to post when I saw the 3600 ibs post.... but wtf? seriously not to start my posting with a flame but if you dont know the **** you talking about PLEASE keep your trap shut. I am looking into getting an xA because I totalled my 02 SE-R Spec V and I will say for a fact SE-R autos don't weigh 3600 and I don't care if you're joking either. They weigh around 2700s and run low 16s averge. The 04s may run even stronger. Anyway I hate to break it to ya hnefrdo but don't think the xA has a chance unless the driver was blind or something :/ Anyway just wanted to shed some light on things. Peace.

 

as much as I don't like attitude in your first post, the guy is right, they do run about 2700 pounds, but that's about 400 pounds over and xA, and the SE-R is an automatic right? If you have a manual I would say you have a slight chance of doing it in... but only with those mods, and even then it's dicey

 

yah...if u have a manual, you will definately win in the quarter mile. after that, he will catch up and pass you

 

Whoa whoa whoa, calm the ____ down, coolio! It was a little typo, jeez. I even said I'd still put my money on the SE-R. The SE-R is about 2700...

First impressions are everything buddy, and you're a dick.

 

thanks for the honest opinion, guys. it'll be sumthing to work towards with a high chance of never getting there, then. if yu guys have anymore to say, say it! please!

i am on a tight budget. all those mods will be the outcome of, maybe, two years of tuning. im so glad i didn't have to move out for college.

 

lol, I moved for college...that's why I ended up with an xA...but no complaints here.

What 14lb wheels are you looking at? I'm thinking of getting some 15" Rota Attacks. My mom's going back to the Philippines in April for some family business. I might ask her to get me a set (they go for 200 bucks a set...450 in the US) along with some balut. :D I don't know though, it's a lot to ask for...

 

sorry man but the se-r's have a gang of tourque so i think he'll take you off the line too... i'm originally a nissan/se-r guy myself so i know the power potential of the motor and honestly it's no contest. but hey if you beat'em more power to you. if it was an older se-r you really have no chance.

 

if you are looking for some lightweight wheels you may want to check out the Kosei K1 TS's. they are 149$ each at tirerack.com and only weigh 10.6 lbs for a 15x7 in. wheel.

PS I think that the SE-r would win no matter what

 

I do want to apoligize if I came off the wrong end however I do admit tht it angers me when people are ignorant about something and instead of posting facts they just post something out of their a$$. And its a typo my bad as far as standing a chance I suggest you go all out with the bolt ons then you stand a good chance imo... so I/H/E ? You friend has an auto with only 4 speed which will cripple the launch somewhat however it has gobs of torque which will be the killer. Keep that in mind.

 

the SER automatic curb weight is 2700lbs

no, you won't be able to take it.

take weight, divide by horsepower.

smaller number wins

 

wrong

even if we assume that the auto is sapping something like 30 horsepower from the SER (And it isnt), thats still more horsepower per pound than a scion XA by a good margin.

 

Power to weight ratio is a good indicator of power, but you have to consider things such as transmission (auto vs. manual) in a race. I still think the SE-R would win.

 

you don't think there's at least a 15% transmission loss there Jack? I mean our manuals have about an 11% transmission loss (108 at the crank ~95 at the wheels) what makes you think an auto wouldn't have a bit more? Just a thought, but still my assertion stands, it's dicey to beat that car with those numbers.. but that sure doesn't mean it will stop us from trying!

 

maybe there is a 15% drivetrain loss

but then the manual has an 11% drivetrain loss

15-11 = 4%

theres nothing dicey about numbers. whats dicey is when people subjectively jump to conclusions based on absolutely no data at all, or worse, incorrect data.

its the same with any car forum, misplaced optimism about their car =)

just as a point of reference, even the base model civic has slightly more horsepower per pound than a stock XA.

Though, we do have slightly more power per pound than the base mini cooper

 

se-r's don't have as much of loss with an auto tranny compared to hondas and other cars. how do i know you might ask. my g20 is auto and before the sr20det swap i was able to stick 200sx se-r's easy and the g20 is at least 300lbs more than a 200sx.

 

...a Toyota Echo weighs 2,035 lbs.

Why do I bring that up? :D No reason.


I do have a question though -- howcome HP is used in the calculations, not the TORQUE? I just wonder in general.

...also because isn't torque on the xA pretty good for its hp?

 

xa is pretty light, i don't think it needs a whole lot of torque, but yea, the torque should be in question shouldn't it?
