I was on my way down to A/C today, pretty much my first trip with the car cause I havent been driving it all that much to see any potential races..

Half way down I see an S4...we were toolin around about 80-90 nothing big and the oporunity came up for a race...I figured it was stock< He may not have been as well....I was in 4th so I didnt even bother goin to 3rd and he toasted me. We raced all the way out to about 120 and he still was walkin me the entire time. I dont understand, I know there relatively fast but I figured I would hang and most likely win...My car is running perfect and feels really fast...it also seemed to got to 120 really quick and boost at its max was about 10.5 (3.125) with fuel pressure maxing at about 90-95....according to the EGT I am running rich which may be why Im lagging...I have the cartech set to Eye...

After racing him twice I went up beside him and wanted to try my luck with 3rd to 4th, but he didnt want to...

Is my car just a dud ?? lol I really wanna believe that Im running rich though
Any assitance will help...

Maybe the S4 was heavily modded...hell I'd love to have that setup. I probably will soon, but In my opinion the max is fast stock on the freeway...can't wait to see how the supercharged version is with 9-11 psi boost!

 

Don't worry there Matt. I had a friend in the car when I saw an 01ish 4dr V6 Accord passing a row of cars coming up behind me. We were doin about 65-70 when I saw him start gainin on me to pass so I waited till he jumped into the other lane to drop it to third. My belt was prolly slippin at the time cause I only saw a max boost of about 4-5psi but this guy hung on my rear quarter up to 120.

 

use 3rd when at all possible.

 

posts like these are always amusing...."how did he beat me, I thought I was fast?" there is ALWAYS someone faster...BTW an S4 isn't exactly slow

 

He was probably modded. How about getting to a track or dyno to make sure of what your car is putting out if you can't tell it's faster than it was with just bolt ons.

 

yeah you should just put on the dyno and see

 

what year s4??

I have seen mildly modded ones (2000-2001) do 13.2's @105 in the 1/4

 

May be this why you lost

v-8 340 hp/7000rpm

WTF is a S4?
I ran into a new Dodge HEMI Magnum the other day with the dealer plate on it. I thought it was a customer test driving it.. we took off from a light and he couldn't get my maxima's front end off the rear bumper of his car I thought I'd ruined a sale......
I later found out when I got some parts for a Buick at that dealer it was the Sales Manager's Demo car!!! I told the parts Mgr to tell the guy I said Hi

is your fuel pressure a typo? If its that high thats the reason 90-95psi of fuel is waaaaaaaaaaaaaaaaaaaaay to much.

 

not with stock injectors and 10+ psi

I would not go lower.. I'd take some fuel out

 

I thought he had JWT with 370cc's?

 

I thought that was Requin??(sp)

 

Yes, 3rd is key. Im sure the S4 got the advantage with you starting in 4th.

 

NO there not installed yet..

90-95 psi with stock injectors is definetly correct for 10psi..you run stock FP 50-60 with larger injectors..

-matt

 

my bad then

 

well...get on the dyno and find out what is going on....and go from there matty or even the strip...

 

Matty, my friend has an S4 that runs in the low 10's and looks almost stock unless you really stop and look at it. those things are little rockets. twin turbo 6 cyl. if it was a 01 or 02.. I have seen him put many FAST cars to shame, dont sweat it bro... My clutch should be in tonight I really need to get on a dyno ASAP, lets meet up and get them both done together maybe we can get a deal... I will make some calls today, my frined just got a dyno at his shop.

 

A stock 2.7T S4 traps about 96-97mph in the 1/4 and can run about 14.0 with a good driver. A chip alone will give the car like 50-60hp and tq, and probably bump trap speeds into the 102-104 range.

Anyways, yeah, this thread went sortof off topic but the point is with a simple mod they are no slouch, you being a supercharged car is at more of a disadvantage because of your selection of gear, since your torque is dependent upon RPM rather than load like a turbo car is. Being in the wrong gear hurt you pretty bad. If you raced a car with an identical setup and power as yours from the same speed, with one car in 3rd and the other in 4th, I'd expect the car in 3rd to probably pull out 2 cars on the one racing in 4th. In 3rd at 80 you are around what, 5800rpm, whereas the car in 4th is at like 3800-4000rpm. Because boost is directly proportional to RPM with a centrifugal SC, the car in 4th gear is only making 2/3 the boost the car in 3rd is at this particular RPM (theoretically). So lets say your car would make 9psi at 6000rpm, you would only be making 6psi at 4000rpm, that's a difference of probably 40-50hp right there. Additionally the car in 4th gear is at a severe disadvantage just because of the gearing, let alone the fact that it is making 40-50 less hp.

 

matty your car aint slow that S4 is just fast. and if he had any work done its faster.my boy has a S4 that i raced and i won, but of course i had to squeeze him the s/c alone wasnt quite enough. he had a chip and exhaust plus four wheel drive, nice cars.

 

Matty- I am running same set up minus the mevi. Can't win them all... Untuned atleast

 

Ok, I'm on the other side of the tracks here - Yeah matty your car is slow....









so send me your mevi and come install my supercharger kit...now.

 

Why don't you go to the track and find out? Racing on the street against cars you don't know the particulars of does not mean too much. The car could have been completely stock or heavily moded...who knows!

 

track or dyno....simple as that....you could be really out of tune plus you were in 4th when you should have been in 3rd...making a dramatic difference...all i know is I beat my bro's 2000 S4 tiptronic NA when I only had intake and y pipe/exhaust....he had exhaust and intake at the time and now he has a chip....but with my udp and mevi and ecu, we are almost even...he walks me up top...!

can't even imagine how I will destroy him when I am boosted! but then again the stick shift S4's are much faster than the tiptronics I believe (remember these cars are freakin heavy), but I know of stick shift S4's that run low 13's with intake, exhaust, chip...of course that is as far as most of them can go without major expensive upgrades from there...

 

if it was an older S4 I wouldnt be surprised if it was a super car sleeper, I have never seen an S4 outlandishly advertising its performance, I've seen ricy 1.8Ts but never a ricy S4, I know a few people with S4s, and even if they run 10s, all they are is lowered with wheels and exhaust, and maybe massive 14" Stoptechs

but you will never know so just like everyone else has said, go tune the car or run it at the track. Also, being a gear too high makes losing sooooo much more easy, I ran my friends E46 M3 and he couldnt catch me until 100+ because I got a jump on him from 3rd gear while he was in 4th

 

HAHA!! i just have to laugh at this guy for this comment.
A Audi S4 will spank on you and no they are not just a4's with, as you say "lowered with wheel and exhaust, and maybe massive 14" Stoptechs"
An A4 1.8T has just that under the hood (4 cylinder engine is 1.8 Liter) while a newer S4 is a V8 4.2 Liter - right there alone a very very BIGGGGG differance. older S4's like a '99 and 2000 are V6 engine 3.2 liter with TWIN TURBO! SO tell me again how they are A4's???

I hate to say it but i drive all types of Audi cars at work every day and an S4 will smoke a Max - even if it Max is supercharged or whatever be it.
Put a chip or tune the newer S4 correctly for racing and all you will see tail lights for a few seconds and then dust!

I am in no way bashing the Maxima - its just they are really 2 different cars & most of all I LOVE MY MAX!!

 

I have a crazy idea, how about knowing what you are talking about before you post, and reading the posts you are replying to twice so you don't make stupid mistakes like you just did. You just posted a ton of misinformation, and apparently didn't read what you were replying to. I suggest you read it again, because you just made a fool of yourself. Also go look up the displacement of the twin turbo S4 before someone else corrects you on it, because you are wrong, about that, and a great many other things in your post.

 

http://www.modernracer.com/archives.html

The fastest in there is listed at 14.2 in the 1/4. Even if those are crappy mag times, that's barely faster than stock 2002+ 6-speeds. A supercharged max will own any of these stock cars.

The 4.2 is not faster than a VQ35-powered maxima in stock form. It can weight up to 3800 pounds.

Also I agree with Neal, and anyone who read the post you replied to correctly will perfectly understand what he meant.

 

like I have said before..., I walked on my bro's tiptronic 2000 2.7L V6 (for you 2000 maxiumus) twin turbo S4 back when he only had intake and exhuast...granted my car is a stick and only had intake and header back exhaust at the time...no udp, mevi, or ecu at the time...now that he has a chip he only walks on me....now I have UDP, and mevi, but found out my ecu is running stock timing for some reason...but the upgraded A/F graphs....(kinda weird I know)...of course his car is about 5-600 lbs. heavier than mine...and is an auto...can't wait to be S/C'ed and destroy all those non KO4 S4 sticks!!!

 

and I have to laugh at your *** for not being able to read... it was quite clear what I meant, I have yet to see a ricy S4, and the ones I know to run 10s and 11s,only differ from stock looking S4s through wheels, brakes, suspension, and exhaust

and I'm not stupid, I know the new A4 has a 340hp or so V8, its obvious to nearly anyone that no matter what shape or form the newer S4s are wickedly fast, I was discussing the earlier 2.7 biturbo S4s which are quick from the factory, and can be modded to be very very quick... I have never heard of a 3.2L biturbo S4..... even the earlier RS4 was still a 2.7L

 

2000-02 S4 came with a 2.7L biturbo not a 3.2L biturbo which you should have known since you drive Audi's at work all the time. If you are gonna laugh at somebody make sure you know what you are talking about or we'll be the one laughing at you. BTW Audi didn't make an S4 in 99 just though you should know.

i think not. i will roast a S4 already did it for some dough. yeh they are quick and come with twin turbos but a good modded max will beat a S4 unless its mod for mod. never underestimate the other car cause there are a lot of factors to winning a race not just its a S4 theory.

 

For some reason I am having a real hard time believing this. A bone stock 2000 AUTO S4 would be at the very worst running a 14.6ish 1/4 mile. with his mods I would guess 14.2 or 14.3 minimum.

 

racing on the street is never precise

I beat a Ferrari in Newport Beach... I swear he was racing!!

a difference between 14.6 and 14.2 is small, especially with driver variations...

 

well...here's the deal..., the auto S4's may run that at the strip...when you race from a roll...it takes away our whole "FWD disadvantage"...so it evens things out a bit...I never beat my bro from off the line...mind you...it was always from a roll...I would get killed off the line...unless I knew how to launch really well like hlh, neal, or ceasar..!

look at our trap speeds and theres....they have great traction...which is why they get the times they do....but our trap speeds indicate bad traction off the line and 60' with the potential (as seen by our trap speeds) to do much better provided we had the trap speed...just look at what maxima's run with slicks...neal-13.6....when you take the traction advantage away...and our no grip...our cars are rather fast...drag slicks are like having AWD in a sense if you were to say neither car gets wheelspin off the line...

and still remember, we have a huge weight advantage...and I have lighter wheels....not to mention AWD and an automatic is highly parasitic...!

 

13.4 actually

 

see, there you go....most S4's with stick, ecu, intake, and exhuast run around there....so it's really the fact that they have great off-the-line traction that gives them such great ET's...but with sufficient traction our cars fully modded NA can keep up!!! which is why from a roll I was always able to either walk away from or hang with my bro's S4...
