Gas Mileage An Excuse For A Turbo Upgrade?

[yokotas13]

well

sounds stupid i know, BUT its true (in my case)

Normally i average 200-250Km a tank

well, after i put this new to4e turbo on....i got 280KM to a half of a tank...

ao thats over 500KM to a tank if i calculate it correctly

ill do a test since i have to fill it up anwyays and i will have a week before i get a tune.

more on that later

[MRO]

thats the evidence i need to explain to the wife the new turbo will be a cost saving! Good work.

Awaiting official results.

[yokotas13]

yeah, im curious to see gas mileage between rough tune and after Rom tune with more fuel delivery parts installed.

im hoping 450+ KM a tank...if i can get 300 id be happy

this 250km a tank is killing me

[_Ryan_]

this could make me keep the stagea!

I am not familiar with that turbo model sorry- but I gather its larger than the stock turbo ?

when does it come on boost?

[yokotas13]

its huge

i had to grind part of the compressor housing to fit it on the stock manifold (stainless had a huge ass crack so i threw it away)

its a t04E size compressor

50 trim

i get 10psi at 4k rpm

im imagining 1 bar at 4300-4500rpm

when i get home i will throw up a picture of it next to a stock turbo for comparrison

[ssshonky]

well I guess thats cause your spending less time on boost.. so the car is running more like an n/a most of the time

What did you do, run it on 2 cylinders only?

Whats that knocking noise I hear?

[yokotas13]

lol

nah

AFs are in the low 13s accross the board

i had liek 2 horus to tune it on the highway.

and nah, i drive my car like a bat out of hell.

thats why i have to maintain it all the damn time.

im never out of boost normally

[ssshonky]

well that makes no sense to me .. hopefully someone will tell is what the go is

Should have gone Autech Grant. 650hp, 400kms a tank.

[yokotas13]

same here, thats why i was like WTF

so far 67 kms of hard city driving and it is still at hte full mark.

[yokotas13]

but, i dont want or need 650 HP

too much HP isnt a good thing always

[_Ryan_]

and 25's are cheaper to replace!

Ill pretend you didnt say that ghey boy.

[yokotas13]

lol

besides, its like working on a z32. no room in teh bay

[BoostedBarge]

Yep, big turbo would be to blaim, when you're cruising along on the highway or whatever it is making less boost and the ECU runs is leaner.

It was the same for me with my old R31 that a HT-18 on it. Most the time was off boost, so fuel efficiency was awesome. As soon as you get up, you can just about watch the fuel needle dropping! A friend of mine with an R32 also has similar affects.

[rb26stagea]

....or the fuel guage just sh1t itself...

[DECIM8]

Well its bigger and your not going full boost at 3g any more which is typical change time.. around there anyway.. damn im going highflow :|

[yokotas13]
