There are many conflicting accounts as to the true standard output.

Vicci Butler Henderson said 308bhp in the Clarkson video when she raced a cossie.

However i talked to my mechanic who specialises in Subarus and he said around 260-270 bhp but with a de-cat as high as 308 bhp.

So what is the true figure?

Do the different sti versions vary?

chrisp

An STI Type R only had one cat (downpipe), its not like a UK car of the time which had 2 (centre and downpipe).

Who know what the real output its the word "PROVEN" is banded around and its laughable. As if it was "PROVEN" then surely it doesnt matter which RR is goes on or if you run it more than once. There are too many variables involved to say a figure is "PROVEN" on a RR.

The Japanese gentlemans agreement was 280PS (276bhp) and that would be what the cars were marketed with. Rumours of some of the last STIs having 300PS (295bhp) were also banded around.

Its also not clever decatting an STI without a remap and also decatting the car will make it illegal and it will fail an MOT but I guess you knew that.

What's the implications of having your STI de-catted without a re-map?

chrisp

I am not an ECU expert, infact I know nothing about them and I just repeating what I have read about STi running lean with full decats, which is very bad news apparently. Plenty of info in the technical forums about it.

Implications are you run a higher risk of blowing up ya motor

DanTheMan

I would say have a look at the dyno graphs on http://dyno.scoobynet.co.uk/ but unfortunately the site is down.
When it did work I recall seeing a 5TypeR with decat & induction kit running at 317BHP but you never know it might have blown up by now, or it might go 100,000 miles at 317BHP......

stiscooby

I have a MY99 V5 Type R and that has a full decat (but has a high flow cat in centre section) with HKS RS air filter and a LINK ECU re-mapped and that runs 319Bhp. I have had it over a year now and has been faultless

Has been re-mapped to run on optimax since so might be fraction more???

Look on the SIDC web site, says Type R's are 300PS which must be about 290-295 Bhp???

Back in 98,mine ran 285bhp and 247lbs/ft torque standard..Alan,Changed a bit now though

Gedi

I have been heavily researching these things for quite a while now as I have just bought one.

The general conclusion I have come to is that if they are run on 100ron fuel:
aprox. bhp - 300bhp
aprox 0-60 - 4.3 secs

sg72

Mines been RRd. and Deltadashed at @ 292 BHP but only 230 ft/p torque.
thats full de-cat & k+n panel. Optimax (no booster).No remap (This will be rectified soon(JB)). 19500 miles in a year.No probs.

Have I been lucky?

Highly recommended IMHO.

Gedi

its probably the 98ron thats keeping your power down.

Due to the fact that your only running optimax and you have a decat, I would say you have been pretty lucky not to blow it up.

sg72

Gedi
I certainly agree about the 98+ ron fuel,giving the lower figures
but as for blowing up I doubt it.

As I see it This car came from Japan (100-102ron) I drove it on SUL+ Booster for @3 moonths till Optimax became available.Then used that since.
I know **** all on the subject of ECUs. But it would appear that given time they can adjust finitely to various conditions.
I think and Im no expert. that most of the engines that have blown , have been with people buying imports filling up with 95or97 ron and going straight out for a blast without being made aware of the fuel spec.
However having said that the knocklink is getting fitted on Monday. Ready for the remap.
Car has been Deltadashed 3 times and shown no sign of Det yet(Oooh I like that Det yet mmmm........Could be Debt yet.

Que the MY WRX STI import grenaded on Optimax replies....DOH!

MY TYPE R MADE 279.8/6501 RPM AT 89MPH 247.1 lbft at 5619 RPM ON CLIVE ATTHOWE'S R.R.
NO POWER MOD'S

sg72

sOUNDS FIT (WHAT FUEL?)

hypoluxa

A Type R gives around 276bhp on circa 100ron fuel.

However due to the different centre diff, the transmission losses are less then other STi's, so they deliver a higher % of that 276bhp to the wheels. Which is nice

sg72, my decated V5 would det badly around peak torque, this was with Optimax and Millers octane booster. Be careful

sg72

Thanks HYPOLUXA>
Didn't want to hear that. Gulp! ........Knocklink on Monday.
May the truth be out.

StickyMicky

i was at revolution today priceing up a downpipe and i asked them "scooby peeps" about this running lean malarky and they had never heard of it or experianced any problems like it

they simply said u optimax spec petrol minimum and octane booster would be advantages

IanW

That was the correct readong for that particular car, which was de-catted.

My Type R made 282bhp and 252lb\ft when it was standard.
it is now making 302bhp and 282lb\ft after decat and on Optimax and OB.

Not to bad just need to get the link done now.

Just dug my old well lane dyno sheet out, my car is a standard version 5 Type R, no mods, and my car was 302bhp and 292lb/ft (using optimax and booster as always)

Had major problems getting traction at the back, so the first 4 runs were spiking quite badly, after the 5th I think my poor car had had enough! Can't see any spiking on the graph, yet I think the figures are a tad optimistic

rhybeck

dont take your cars to t.d.i. in barking very inacuate my type r just span wheels on rollers about 8 times they tryed.

they must lock the c.diff to have a chance.

5 Type R

In standard trim on Optimax when the car came across from Japan
my STI 5 Type R was dyno'd at

272.6bhp and 230.3lft.
FACTORY FIGURES SHOULD BE: 280ps = 276bhp/36.0kg-m = 260lbft)

This shows that the lack of 100RON fuel has cost a little hp but mainly 30lbft of torque.
The car was running smoothly at this time and all plots and variables seemed OK.
Spec was totally standard mechanically.

To be honest performance felt very disappointing compared to the MR2 Turbo running 330bhp that I sold to get the scooby and the figures confirmed this.

The Current Engine Spec is now as follows

Dastek Unichip Mapped to Peak 1.45 bar and hold 1.2bar
Dual Pump Water Injection System (Controlled by Unichip)
H&S Downpipe
Blitz Nur Spec R System
K&N Panel Filter

310bhp (249 @ wheels) 309lbft

The car is now completely different and a complete beast with the short gearing. As mentioned in an earlier thread the 310bhp may not sound a lot but nearly 250 @ the wheels is what a lot of cars struggle to get with nearer 350 flywheel horsepower.

Just before anyone questions the dyno, this has been run on 3 different dynos now all reading within a few horsepower of one another.

IMO , I would be very suprised if any stock Type Rs come across running more than the factory 276bhp/260lbft

chrisp

Yep forget flywheel figures my RA ran 195bhp at the wheels which is more significant IMHO. Funnily enough none else has posted there power @ wheels figures .

Tractor

Oi Oi Oi about all this blowing up stuff. It's the Sti V and VI that really don't like decatting, just as they're really sensitive to fuel. I am not saying that earlier Stis are SAFE, but they are SAFER, according to what I've read on here when it comes to decatting etc. So those of you with decatted Sti 2s,3s, and 4s, don't be terrified by what you've read on this thread....

And I'm sure someone will disagree with me

sg72

My STI V Type R was running 292 BHP and 230ish ft/lbs, with SUL+booster. Same figures with Optimax Thats with de-cat and K+N panel.
I say was because its just blown up today.

I kid you not.

Just had Knocklink fitted ready for Deltaecu.

Lucky white heather anyone?

5 Type R

Gutted..........How did it go pop mate.

After long dual carriageway/motorway run?
Full boost back roads?

Interested to know

sg72

Haven't a clue mate.
Had posted yesterday about Lambda sensor failure and its connection with poor idling. Kinda thought that this was causing faulty running
Got home today with billowing blue smoke and coasting engine.
Read replies to post doesn't appear to have been that.
Daftest thing is I had been Going on about how I'd covered 20,000 miles this past year,Running on Optimax alone.
then took heed of all replies, to use booster and fit knocklink.
then Boosh. **** happens ..........................Still love my car. However the expenditure may end in divorce (Wife not car)

Sorry to hear about your bad luck, hope you get it sorted soon with not too much of a dent in your wallet.

How long had you been running it with a full decat?

Does anyone recall a STi5 blowing up in the UK running it standard? There was a load of talk a while back on the oil pump possibly being the cause of engine pops.

sg72

megastream
Thats exactly the route im thinking of now. Think I read somewhere about No. 3 cylinder going pop due to faulty pump.
I thought this would explain the rough running, that started last night
Car has been De-catted for almost a year.
Checked oil on Sunday Ok . Now I think its spat most out.
