just bought my car a few weeks ago, and its got a dyno map with it saying 279 bhp, will this be chipped to get this, its got full uprated zorst system and induction kit, but thats about it! it boost just under 0.8 bar is this right thanks

 

I would say chipped,but am sure someone more informed will be along soon.

 

What year is it? With just under 0.8bar, I'd guess it's not been chipped.
Nice healthy result, whatever!

 

What years your car and is it an sti ?

 

It all depends on the year, 92-94 WRX's were quoted 240ps (237bhp) 95-96 were 260ps (257bhp) and 97-00 were all 280ps (276bhp)
Note this is for the SALOON version only, the wagons had a different turbo and produced less power (unless it was an STi).

hi its an l reg so 93-94 its done just 50000 miles with fsh but im only getting about 200 miles for £40 is that rightit isnt an sti and is a saloon

 

0.8 bar is as near as damn it waste gate pressure. Is there a pipe from the turbo nipple directly to the waste gate? Mine was rigged this way when imported and wasnt using the ECU to control boost. It looked like an aftermarket boost controller had been removed prior to importing it into the UK.

Just be careful about plumbing it back in if it is this. There may be a reason why they reduced the boost.

 

0.8bar is arounf standard for a 1993 WRX.
279 is a good result with just and exhaust change. It could be running a little lean due to a faulty MAF which would give high BHP but may be getting dangerous.
If it was a good RR setup they should of spotted this.

 

ive been thinking about getting it rr is there anywere in the northeast that can do this and give it a tune up cheers...

 

my 94 classic is not chipped or anythin and is running 271 bhp

and yeah that fuel is about right

 

Also, 200 miles when driven in a spirited manner is about right. I have just been testing my fuel economy in my MY98 WRX (modified) and can get 27mpg the motorway. This is with very restrained control, keeping it well off boost and with very progressive acceleration instead of booting it all the time.

80mph seems to be around the best speed for this.

45.77 litres at a cost of £1 per litre just for ease of calculation.

45.77 / 4.55 = 10.06 gallons

270 miles / 10.06 gallons = 26.84 mpg.


so £40

40 / 4.55 = 8.79 gallons

200 / 8.79 = 22.75 mpg

 

oh good well must be just a healthy lump hope so, ive checked fault codes and it only picks up knock sensor, but this only showes when cold if left to warm up to then no faults show.
