What does the mpg go down to after an rst has been chipped and running about 170bhp. obviously the way its driven determinds it but say cruising at 75. would it be any different to cruising at 75 when not chipped?

Get a 2 stage boost switch if you're worried about it...............can't say I notice on my car but I'm not looking. I only do about 500 miles a year anyway and she's a sunny Sunday morning car so I don't really care !!!

grunter

must admit i think mine is rather good on fuel well before the turbo blew get about 180 200 miles to 25 quid and runnin on super that is just a rough figer and of course not hammering it all the time

thelynx

mine wasnt that bad really,but its hard to judge sometimes with the petrol cost goin up and down

petermintrst

i'll have to add i use the car for 12000 miles a yr, and i struggle to afford petrol when its standard

i got exactly 302 miles out of a tank (before i ran out ) and my car is chipped. 29mpg

won't have much effect if your just cruising at 75 cause your off boost anyway.

oh and i was properley caining it as well

petermintrst

cheers dave, the minute im on boost i get a whining sound from the turbo, so me thinks a recon is due before i chip it. one way to finish it off

thelynx

You need to get a better paid job then or drive it less

thelynx

hehe mine used to whine a little when standard, 3 days after I changed the ecu and upped the boost I took it to get set up, on the way home boom turbo went.

crawled 30 miles home trying to keep it under 2k or smoke would piss out

petermintrst

cheers for the first bit - greatly appreciated

petermintrst

again, greatly appreciated that you find it amusing that i might have to spend more money on my car. i am overwhelmed by your friendly helpful approach to my question

the standard Turbo is supposed to last about 80k miles i think i read...?

yep i think 15psi would polish off a standard turbo, while your there you may as well upgrade it and make it future proof.

by the way make sure you know what your doing cause chipping an RST is just the start of it. next it will be an intercooler, then clutch, then gearbox, then suspension, then brakes etc! not cheap!

petermintrst

i didnt think it was a case of exhaust actuator & chip. i could live with that.

my cars on 70k now and its just started sirening. new turbo or recon?

Mr S1

iTrader: (2)

Codswallop mate provided the turbo is looked after and cooled down properly you'll get more than 80k miles.........and 15psi may blow it if the turbo is hanging but if it's a healthy one she'll handle 15psi all day long

petermintrst

so whats wrong with mine i've done regular oil changes and let it cool down.....the owner b4 me did short journeys though and it sat for a yr

dave_y

iTrader: (4)

im not gonna deny that im probably wrong, as i said i thought i read it somewhere.

my car had a new turbo about 8k ago (standard spec) and its dealing with 15psi just fine. im gonna treat it to 18psi soon as well.

just for the record my car kept its original turbo up to 100k (just to prove myself wrong lol )

Mr S1

iTrader: (2)

Only takes one bad owner to screw a turbo mate...........it could well be shagged and sounds like it is TBH...............all I was saying is if a turbo is looked after it will sail past 80k miles and handle more than 15psi.........mine's standard, done over 80k and I'm running 16psi, chargecooler etc. I don't want a hybrid, but if / when mine does give up the ghost I'll get a stage 1.

Mr S1

Taking the piddle mate

petermintrst

so is mine fooked if it sounds like a police siren when spooling up? just so i know.

Mr S1

iTrader: (2)

Yep that's shagged. Probably catching on the casing. Want to be a bit careful in case the blades shatter - new engine then mate...........

petermintrst

oh balls! so keep it off boost then and get it changed!.

how much are they?

dave_y

iTrader: (4)

about Ł450 for a standard unit.

Mr S1

iTrader: (2)

Yep...............

thelynx

Forgive me for being daft, but why have the car if you cant afford to run it

Also, I was not laughing at the matter, I mearly pointed out what happened to mine when it whined and had it chipped... Dont have to tell me about spending money on these cars, they cost a small fortune

thelynx

I got my new unit for Ł350+vat

Linsay

Mine gets about 230 - 250 miles to a tank, with instances of ass kicking here and there

but can easily get about 40 miles to Ł10, as i enjoy driving it more now with the current spec , so can be an unfair comparison

dave_y

iTrader: (4)

so Ł410 after VAT which is close enough to 'about' Ł450.

thelynx

T28 RST

I get between 60 to 70 miles to Ł10 of fuel, on longer journeys i can see 35mpg

thelynx

What even with your power? I barely got that when mine was standard

T28 RST

Yes

My best is 300 miles to Ł30 of fuel

thelynx

Thats impressive wish mine was that economical, must be my lead boots wish I could take them off

petermintrst

thelynx

i can afford to run it if nothing major goes wrong, if i didnt have my car im liable to go slightly nutty. Only enjoyment! sad but true

grunter

the turbo on my cossie sounds like a police siren 2 been like it 2 years running 18psi as a standard unit no problem..................... before i get any wise smart arses i know were not talkin about cossies here was just passing comment......... it could be summat as simple as a split hose or leakin gasket correct me if im wrong?????? look at obviouse things before condeming it i.e breather...... is it burning oil?????? does it boost up nice and hold it????? is the power nice smooth and constant????? just done the turbo on my s2 wen the old 1 let go lots of smoke appeared was burning a litre of oil per 50 miles would boost up and pull 4 a few seconds then go really flat bearings and seals gone and also turbine housing cracked on the inside near waste gate

Linsay

Is unlikely to be a split hose or gasket, rst's don't like air leaks. Mine wouldn't run right when i blew the bottom out of the little gasket on the inlet oops

another passing comment here, my Turbo Technics stage 2 lasted over 80'000 miles, think i was told they do about 30-50k
It lost a fin on the exhaust side when i had it flat out coming back from germany, might have lasted longer if i'd have had a bit more respect for it
