So I was going to complain about lack of power at the top end, but then I found the reference to the output on the wiki page.
B4194T,
147 kW; 197 hp @5500
300 N·m (220 lb·ft) @2400–3600
Makes sense as to why it dies in the arse once it gets above 5500.
What I can't find is a print out of the torque curve? How much does it actually fall away there after?
Is a strange feeling coming from motorbikes and high revving NA engines. With this, all that glorious torque but with a dismal high end.
It's still a laugh however :P

Rear muffler delete will boost the midrange and top end.
In my silver car (no rear muffler, probably a bit more boost), it takes care to avoid limiter bashing when you're having a fang - it's still pulling strong at 6500 when the limiter spoils the fun. It could really do with the rev limit being raised 300-500rpm to keep it right on song after the upchange.

That's all it took, a better breathing exhaust. Well indeed.
I suppose he next question should be is these ECU's, how much compensation, well fuelling and spark adjustment do they have for boost above 12psi? (assuming that's the default position) Again I can't find much about these ECU's other then it's a Siemans.

I've read so much conflicting shit on ECU stuff that I refuse to believe any of it until I work stuff out for myself.
I haven't even found a credible figure for the factory boost level (hence my ambiguity in previous post). Mine peaks/spikes at 14psi, and sits on 12psi.
Concencus is that above 1.3bar is where stuff gets problematic (including conrods) but I haven't seen a clear statement about "you need a chip after 1.x bar" or anything like that.
FWIW, The Wife used to fill the old green T4 with 95 octane E10 or 91 octane dishwater on occasion, and the silver one has had a few tanks full of 96. It did drop performance a bit (particularly the 91), but neither car showed any signs of unhappiness - it's hardly scientific, but that says to me that the ECU can cope with a fair bit.

Ah ok cool. Yes I concur there is so much crap floating around, so thanks for confirming that I'm not going mad and simply failing at a google search :(
bowie
Oh I haven't had a photo of it on a road, legally with a licence plate. Shame on me. Presenting the angle that had me fall in in love with it months ago :P
RAAAAP!

They do lack a little up there. The VVT version pull even harder at low revs.
I think it is tuning thing to lessen turbo lag.
A my 850r T5 pulls a fair bit stronger up top but lags more.
bowie
Well fixed that crappy top end.
It's much nicer now :P
UNM
Those plugs look like crap.
bowie
Agreed. New plugs work wonders. It's like.. Magic :P
bowie
Those clips that connect the power to the coils atop the spark plugs, that then share to the other cylinders.. Fancy these things running a wastes spark setup. Are they a common Volvo part, i.e Can I replace the male end of the clips with fresh ones easily? Mine are only staying together on the terminal with the aid of electrical tape....
And now the engine warning light (which looks an awful lot like a Half Life symbol) wont go away.

I think the early models are obd2 compliant.
So grab a $20 bluetooth dongle and the free Torque app, you can pull/clear codes and lots of other cool stuff.
UNM
Agree with nicko.
Any 'ELM327' bluetooth dongle should do the job. Don't load the free software that comes with it unless you have up to date virus protection, mine was badly infected.
The free android app called 'Torque' gives good basic diagnostics. I bought the Torque pro version for a few $$ and it does have a couple extra bits and bobs.
'Genuine' volvo diag cable and s/w will be way better, but the basic bluetooth one is well worth the small investment. I have seen them as low as AU$4.97 on fleabay.
nickm
The other option is Vol-Fcr and a vag com cable. There are a few versions running around the net.

Those coil wires and plugs are made of crumble. Maybe common with p2?
bowie
Cheers all. I'll investigate. And I must fire up a parts catalogue and do some searching for comparisons.
bowie
Well the s40 is going well. I've had it a month and lost 4 points of my licence. That's over a point a week. Tsk tsk :(
But still.
Hehehe ah its god fun.
But no more points please. I've had my fun. :(
Spac
They do that.

Get a gps with speed alert
Mine has done a dam good job keeping me from losing any points in my bmw
bowie
Well the GPS didn't help.
It's just the rush through that tall 2nd gear that got me again.
I have to be good for 6 months now.
Stupid wonderful Volvo.
