arrg! everytime i run my car its around 0-60: 4.6 and i dunno the 1/4 mile shouldn't it be faster for what i got and it gets 180 miles to a full tank of 91 gas on the streets and 260 on the freeway im only pushing 10psi til i get my car tuned for the mods so i don't blow her

so whats holding me back?

heres what i got

Street Large Port 13b engine

Factory twin turbo setup converted to non-seq pushing 10psi

Unorthodox lightweight engine pulleys

Goodyear eagle GT+4 in the front being replaced with 245/45/16 bidgestone fuzions ZRi in the next new days

^?maybe its my tires?^

 

Where are you getting the 4.6, 0-60 time from? G-Tech?

 

180 street and 260 highway?! Holy crap that sucks! I almost have same mods as you but I get about
200 street / 450 highway, but thats when I push it to get the most out of gas. But if I drive with some punch I get about 180 street 380 highway, and thats with left over gas in my tank too. O and btw 4.6 0-60 is pretty fast my friend. I too would like to know where you are getting your times from? if its from a stopwatch then you are gonna make me laugh.....

 

stopwatch lol
yeah yeah i know i need to get it timed at a track i will when i have time but 4.6 is pretty consistent when i time it and i get 260 if im going 65 if im going 160 then yeah i get 380 lol it seems i use less gas if im punching it everywhere

 

Don't bother comparing times until you can get a worthwhile method.

 

ok

 

yeah thats what I say.

 

LACR?

 

lets go!!! im down!

we were going to set up a track day if you want to come?

also, i would think it might be the backpressure from the stock exh but thats not a big chance?

 

well i need to get tuned on the dyno and new tires before i go to LACR and blow my engine lol

 

Regardless of what mods you have if you get that badboy tuned correctly, it's very possible that you could get stock level gas mileage. You really need to lean it out under light loads. Hell with 80k original miles, I get 270 mpg in the city and 400+ on the highway.

 

good advice thanks

 

ummm get a catback before you have it tuned
you are probably losing 10rwhp with that thing

 

lol
read my earlyier posts i can't because i live with my parents so til i move out i need a quiet exaust

 

my car has a large single and its almost as quiet as stock
borla xr1 in the midpipe and greddy sp catback there you go

 

wtf? you have 2 different exaust systems?
or is the borla xr1 a pre silencer
I don't get it

 

I had an HKS mid pipe, Greedy down pipe and apex catback, not bad there's an increase of 25 HP when i dnoed my FC with 10 PSI of boost!

 

the borla xr1 is a muffler that is welded into the midpipe
it has been used for 25 years the exact muffler in racecars porshes etc
it makes my car quiet to the point where you can hardly tell its on from 10 feet away and only takes away a few hp

also gets rid of the **** rotary sound

 

The RacingBeat cat-back seems to be a nice improvement while not too hard on the ears. I fully intend to get it once I start modding more.

holy crap that mpg is horrible! lol

last time on the highway, i got 144 miles on a 1/4 tank with some boost here and there, so lets see 144 x 4 = 576 miles per fill up.. wait, that seems wrong..

576 miles divided by 20.1 gal cap = 28mpg

wait, that seems right

 

dude you must have it wrong and a FD3S dosn't have a 20 gallon tank stock i think its 14 correct me if im wrong

 

austinsFD, Fd is supposed to have a 20 gal fuel tank, but when I fill it up(low fuel light on), I've never gotten more than 17.5 gals in the tank. I've never run out of gas either so I'm not really sure how much gas is really left in their. I always calculate my milage based on how much gas I actually get in the tank.



ulost2my7, Remember just because the gauge says is has 1/4 left doesn't mean that it actually has that much in the tank. In most cases it's just a referance point(doesn't mean it accurate).

 

Read your owners manual. It clearly states in there the FD comes with a 20 gallon tank. I'd scan it if I had it at work with me.

 

sounds like an O2 sensor or something wasting your fuel....I agree with freeway milage of 400+ per tank....driving conservativly

 

it was an estimate

and yes an fd does have a 20 gal capacity as stated in the owners manual and from experience

my buddy's 94 had a cracked gas tank, he replaced it, pushed it up the block (about 50ft ) and filled it up and it read 19.7 gals or something..
