Who Wins? XRS vrs 6psi boosted 01?

I was just sitting around and pondering stuff and was thinking. Which has more HP and which would would win in a 1/4th mile race. A Corolla XRS with VVTL-i or a 01 VVT-i running 6lb of boost? I want to turbo my 01 Corolla but I may decide not too if a turbo setup pushing 6psi on stock internals will not put my car outside of the NA league of Corolla's.

6psi is safe on a 01 Corolla if properly done... I think the turbo corolla would have an edge if properly setup

^I'm with stupid^

Meh, I wish. I'm nearing the completion of swapping a 3SGTE into a Celica ST. Then I've got an MR2 that I'm swapping a silvertop into and building megasquirt for and then tuning it good. (In between there I need to put a clutch in a Celica, Corolla, and probably do a rear disc conversion on my Jeep). Then I've got half of a 3000GT Twin Turbo that I'm using to convert a base 3KGT with. Then after that I don't have anything scheduled for sure (which means I could potentially work on the turbo kits!)

I did, heheh...

turboed vvti will win.

xrs is slow.

Given equally skilled drivers, 1ZZ with 6 psi of boost will never touch the XRS. Not even close. Whatsoever. It is common sense for people who actually drive the car. Guaranteed. XRS puts up consistently time slips in low 15s bone stock with good drivers (15.3 with 93 mph trap speed). With intake and exhaust, it is a different story. With 10 - 12 psi of boost, yes and it may beat it. No way with 6.

does ne1 have any actual dyno figures on a boosted 1zz

hahahaha this is funny, all the people with the 01's are saying it will spank the XRS and then the one dude with the XRS is saying there is no way it would touch it. Sounds like a lot of people protecting there rides honors hehe. I just need straight up Dyno's from an 01 Boosted and an XRS and that would sell me.

The last thing I want to do is to engage in childish "my car is faster" arguments because I don't care. Recently there was a race between S/Céd rolla with intake/exhaust and header (al6176) and Corolla XRS with intake and exhaust (Bio) (not 200 lbs heavier Matrix XRS that raced a S/Céd rolla S). The first race, S/Céd took till 70 mph and XRS took after that. Second race, S/C'ed could not outlaunch the XRS and XRS took lead off the line. Everyone agreed that it is a close race between the two with equal drivers.

Here is the link to the story (by al6176

p.s. S/Céd has much better low end because of no boost lag. Supercharger delivers power much more effectively at low revs than a turbo. Turbo lag will kill it off the line because of the super short first gear on the XRS and 6 psi is too low of a boost to do any serious damage once they get out of first gear.

p.s. Dynos do not reflect the faster car because there are other factors there i.e power to weight ratio, power delivery, torque delivery across the rev band (more important than gross peak torque at one point on the graph), gear ratios, differential ratios and powertrain loss etc. If anything, compare what is the best run consistently that is possible in both cars. Like I said before, XRS is putting up timeslips of low 15 secs bone sock.

Cadetlee runs a 15.9 in his '98 with some pretty minor mods... with a well-designed low boost turbo system, it would easily beat the XRS. Like you said, it has to do with where the power comes on in the powerband, and the turbo will apply much more usable power then the peaky 2ZZGE.

Like I said before, a Supercharger running 7 psi of boost will perform much better all across the rev range than a Turbo with 6 psi of boost on the same. Look at the link I posted above about a race between S/C'éd rolla vs XRS I gave above. In the end, everyone has his opinion. I just gave some things to think about. That is it.

p.s. I have raced my friend's well tuned and rebuilt 1991 Mazda RX7 Turbo 2 running 7 psi of boost 3 times with intake and exhaust myself.

I agree. I think I opened up a pandora's box asking this question because everyone will defend there ride and anyone can find information to support an argument on the internet. I think I just need to go with my gut and do the turbo. With 6psi of boost with an already 11:1 compression ratio I should gain atleast 50 - 75whp which would put me over the XRS in the power department. So now build me a turbo kit already

You raced a well tuned 1991 Mazda RX7 running 7psi and won? or just raced him?

I thought you would take a hint.

A 1991 Mazda RX7 2 Turbo has 200hp with stock boost and 195lb of torque. If you won in your XRS then he wasn't trying or his "Well Tuned" was more like "Completely busted" I'm not trying to rag on you but I think your just trying to pimp the XRS a little hard because you own one. Thats cool and I think there badass cars but I want the fastest of two cars, an 01 boosted or an XRS. Also I'm kind of partial to turbo because I love the spool and blow-off noises. Anyways I like your car but I agree with Dr. Tweak that the turbo corolla driven correctly would own an XRS driven correctly.

Don't think I'm a hater, I'm the guy who swapped a 2ZZGE into a '98, remember? I like the 2ZZGE a lot, but I still know my stuff and this is how I think it would go.

Also, you're not correct about a supercharger making better performance than a turbo. The one advantage to an s/c is the throttle response. Other than that, the turbo is not only more efficient, it's also INTERCOOLED, which the s/c is not!!! :sad: Colder air = denser air = more fuel = more power!!!

2005 XRS

1/4th mile : 16.1 @ 89mph

1991 RX7 2 (turbo)
-------------------
Power : 200hp
Toque : 198lb
Weight : 2800lb
1/4th Mile : 14.9

The QM times were from (http://auto.consumerguide.com/Auto/Used/reviews/full/index.cfm/id/2345/act/usedcarreviewspecs/) so you can check them out.

16.1 secs sure is a joke (by none other than autoweek considering a 1ZZ Corolla does it in 16.2 secs according to autoweek).

By all means, turbo your car and be happy. I hate getting into arguments and looking like an XRS fanboy and an a**. One of the reasons why I don't come to this site anymore. This is just to get some things straight on this post. I am out of here. Bye.

peace

Hahahaha, peace.

What's the big deal? Not everyone is going to agree with your point of view in life, get used to it. I don't understand why a little discussion has to turn into "this is why I don't come to this site anymore!!! Wah wah wah!"

Here's a quote from your first post in this thread:

"Given equally skilled drivers, 1ZZ with 6 psi of boost will never touch the XRS. Not even close. Whatsoever. It is common sense for people who actually drive the car."

Would you say that your original statement is perhaps not 100% accurate now that you have seen some new numbers? All right then.

/\seriously....

no1 was flaming you, if they were i can understand you not wanting to come here, people were just pointing out some facts that proved your statement might not have been right to begin with, its happened 2 me many-a-time
moral of the story: dont post what you dont know

I'd say good riddens. Things are much more peaceful here without people bringing up these pointless ass arguements.

I'm sorry I had to ask the question and spark a civic war in the Corolla community

LoL I dont usually come to start arguments but a 01 corolla with 6psi boost.... thats well tuned even shitty should take out an xrs.... 170whp stock or 146.6 whp and 105 wtq roughly.... its been between 140 - 150whp for most stock xrs

DYNO: XRS


hmm that seems slow to me... now a corolla with 7psi (yeah its not 6 psi boohoo and its a 00 not an 01)

221.1 WHP and 191.2 WTQ and thats not even that well tuned....

Now 6 psi we will say i lose 21.1 who which it would be less.. but thats 200 whp to the ground! On a car that weighs less then an xrs and has the same drivetrain pretty much...

DYNO: 2000 Corolla 7PSI


Now assuming the corolla has 200 whp... thats 40whp more then the xrs. The corolla weighs less as well... now Unless the driver forgets to hit the gas your statement above is almost right...

"Given equally skilled drivers, 1ZZ with 6 psi of boost will never touch the XRS. Not even close. Whatsoever. It is common sense for people who actually drive the car."

The difference being the XRS will never touch the 1ZZ Corolla... also turbo lag is stupid... im fully spooled before 3500 rpm... Its not a match the xrs would eat dust.... and dont come with BS liek the XRS is all motor so somehow HP means nothing or turbo lag which hurts ya for off the line only makes a difference..... they have raced celica gt with supercharger and turbo at the same psi and the turbo won so this supercharger being better is some bull as well....

In the end your XRS is slower then a boost 1ZZ.. THE END YOUR WRONG!

Wanna prove me wrong ill take you on at a track... my corolla probably weight 500 pounds above stock with the stereo in the rear and ill turn it down to 5 psi and still spank ya most likely!

Oh 2000 corolla ce curb weight Curb Weight: 2426 lbs.

So I also have a 224 lbs bonus... although my stereo system cancels that out...

so a 1zz that weighs less, has more hp with a turbo, and is built on the smae chasis nearly yet the 1zz should lose?? Im really lost with this argument!
