cool but I have a gauge that works in bar !

psi/14.5 = bar u do the maths

[RobEvo5]

So mine should be running 1.13 bar !. So 1.5 + held will be nice.

[BIG"E"]

What about a : WRX STI WR1.

You let me hook up to the car and I'll tell you....

1.5+bar held LOL..... any more then 1.2bar at the top end and the VF turns into a hair-dryer.

[RobEvo5]

New I should have bought a Mitsi Evo . They will run 1.5 all day long on stock set up.

Having had a tangle with one about year or so ago, when I had my green 2.5 classic in mild state of tune and about 330bhp, I would say its running the same boost as what ever the TSL333 map might be - I remember it impressing me, and certainly could out break me as I came to the tunbridge wells roundabout.

The Evo VIII I 'followed' today wasn't running 1.5bar held, as my lowley UK scoob was gaining on him........my defi peaked at 1.5 though....(they do read a little high).

[RobEvo5]

Possibly a UK GSR 260 varient. But the base 260 can be wound right up to MR360 power without changing a thing other than the map.

The 260's come with a low spoiler, but nearly all of them have upgraded to the larger rear spoilers.

Defo not a 260.
Reckon more like an FQ300 or FQ320 bearing in mind I'm probably running alot lighter then an EVO VIII.

He was also baiting me and overtook me earlier to make a point...if it were a 260 I doubt he would of dangled the carrot so much.

Both acknowlegded one another after which was nice....

Trying to compare like with like a WR1 pushes out 320 and according to an old article I just happened to read. The WR1 has identicle 0-120mph times as a 276BHP P1.
WR1 looses out due to weight and too many gear changes (6-speed).

I'm also probably running 35-45more BHP then a P1.

Off topic a little if anyone has a boost gauge for sale please let me know

Don't just go for a boost gauge, go for a full set : http://cgi.ebay.co.uk/DEFI-STI-GAUGES-6 ... 286.c0.m14

Probably worth £200-£250 as sensors need sourcing.
And you will need an MY01 Pod as they are in a Classic Pod
http://cgi.ebay.co.uk/Subaru-Impreza-Tu ... 286.c0.m14

New Items without the STi Logo :

http://cgi.ebay.co.uk/Defi-Subaru-Impre ... 286.c0.m14


Or Cheaper style Defi Copies : http://cgi.ebay.co.uk/NEW-SM68-Electron ... m153.l1262

To be honest after wanting Defi's for years and now having them, I reckon the copies that are around now are just as good.

http://www.rspec.co.uk/index.php?main_p ... cPath=3_83

The next thing to decide is 52mm or 60mm ?

If you only want a single gauge then most pods are 52mm.
If you want a set then you normally have the option for the centre triple pod of 52mm or 60mm.

That might have been me!!!!!!!!!!!!!!!!

[RobEvo5]

I think it probably was mate Not too many WR1's about especially this kneck of the woods.

[stig this]

im running just over 1.5 bar @ 311bhp but i do get intermitant fuel cut not good

[MIDLIFE]

Being a bit thick does the 2001 WRX and the 2001 sti (jap spec) have the same boost figures? thanks Paul.

No

Impreza WRX 2001-2002
ECU Code AF530 : 13.61psi
ECU Code AF531 : 13.61psi

Impreza STi 2002
ECU Code AG820 : 16.4psi (peak)

(Not JDM figures, but will be similar, if not higher)

[Anger]

Im guessing my 1.8bar is a little more than standard lol

[viper1982]

Good, I haven't connected for a while. I want to ask you a question about a Boost topic. I have the doubt that it would be more advisable in terms of the increase in Boost and efficiency, if I go testing with the diameter of the "pill restrictor" or otherwise replace the "wastegate" valve with the Kinugawa or similar with the possibility of changing the different springs with different degrees of sureness, my question is specifically if it is justified to place the wastegate with harder springs, or if the behavior would be better with the original wastegate and go altering the diameter of the pill to obtain the desired results? What is better? Who gets better results without having so many pressure spike problems?

My current configuration is a prodrive ECU MY99 AE801 with OEM turbo TD04L-13T (9-blade turbineof Kinugawa) Larger Intercooler, K&N filter, Equal Headers and 3 " full decat exhaust. Walbro 355LPH, 550 cc. Yellow´s. Samco IC hoses & Inlet too.

Thank you
