What power am I looking at?
Right, I know everybody asks this, and the best way is to get it on a Rolling Road, but for now, you guys on here seem to be pretty accurate!
94 WRX (240PS)
Mods only: Sti Panel Filter, De-cat Downpipe with wide open mouth. 3" System to back. Bailey DV.
How much increase in BHP am I looking at?
Some recommended Rolling Road places in the South would be appreciated.
Thanks

I'm not sure what ECU it is, I can't remember if mine is end of 1994.
Just with the de-cat, feels a hell of lot quicker!!
What are the prices for the Rolling road at Janspeed? Can't find prices on their Webby.

The ecu is under passenger footwell (5 min job to get at it should have a sticker on it).
Turbo spools up quicker as the decat is less restrictive.
Don't know the prices you could phone them and ask.
This is your local club Hampshire Subaru (if you didn't know about it)

WRX/STI saloons 2C, U8, W6, and W9 11.47psi held to redline fuel cut 14.57psi
WRX saloons (95/96) Z4 12.71psi dropping to 11.78psi@6600rpm fuel cut 15.65psi
These are the differences and whilst it doesn't look much different the way the car accelerates is much better (holds on to the boost longer,better fuelling even Prodrive used the z4 map increasing the boost)

So 236bhp + approx. 15bhp = 251bhp ish? Perhaps a couple more as you have a decat downpipe instead of sports cat?
All guesstimates of course, rolling road will give you a proper figure

From my own experience with my UK Turbo, 15bhp was gained by changing downpipe (albeit Ninja Sports Cat), Magnex decatted mid section/backbox and JR Panel filter swap.

Well the UK94 wagon I had had a full decat, induction kit and a dawes device which allowed me to raise the boost to just under the fuel cut limit, on a RR it got ~290bhp, mates UK96 wagon with the same mods (except the DD) got about 260-270bhp IIRC.

Very surprised you had 290 as normally full decat and remap on a TD04 produces 270-280 max.
But it obviously happens - a lot of variables, for e.g. what rolling road was it?
Mine was Powerstation who are known as being conservative?
Was your mates wagon dynod? Amazed he went from 208 to 260-270 with just a decat/panel filter change?

These cars can vary alot.
I know of a UK saloon that recorded 290BHP with just exhaust mods, even the RR involved were suprised.
One of my chips then went in (I think it was a 14psi map) and it hit 311BHP.
I recieved a email from a guy last week with a UK wagon, who just fitted one of my 16psi chips and a decat and filter and he got 297BHP and 275lbft.
It must be said though that these are the exception rather then the norm.
I would expect a UK or early WRX running 16psi and exhaust/filter to be around 275BHP-290BHP depending on health and vehicle tolerances.
