Same here Jon
staffi, i recently took Alan Bell out in my own car, he was used to his sti7 running 450bhp/480lbft back then, and he could not believe the difference in acceleration between the 2 cars.
His is an instantaneous flat torque curve, with over 400lbft available from 3000 rpm. Mine isnt, its a different hit, but when it hits it hits hard.
At that level, i maintained that his car was the best everyday impreza i have driven, because it had bags of grunt available, when you wanted, and most importantly, the chasis wasnt screaming blue murder at you.
Alan's now pushing out 500/530 and it would be interesting to compare them now.

So how is a 500hp car worse than a 400hp car ? In the end, if you are sensible, it doesnt matter even if you have a 1000hp car, as long as reliability does not become an issue.
When you have more power It just means that you dont have to push your car very hard to go as quick as a 400hp car would go ( or a 200hp for a matter of fact ). But when an opportunity arises you can enjoy your car to the limit, whereas a person in a 400hp car would be wondering - what would it be like to have another 100 more hp ?
When you have the exact ammount of power that you require, you will stop wondering what would happen then - untill then, keep upgrading!
If your car is too much for you, just lower the boost and sacrifice some power for reliability, thats the beauty of a turbo engine!
On the other hand if you cannot drive without pushing your gas pedal to the floor everytime, i think you are better sticking with a corsa anyway.

its all down to power delivery , when you floor your car in 2nd/3rd gear on a normal road things pass you by a lot quicker so you have to think before you hit the loud pedal
a quick press for example could mean 100yards but in a normal impreza your ok

. A gas pedal is not just an on/off button mate

Generally the more power you have the bigger the delay in achieving boost. For example 500bhp on a 2.0 is not an easy car to drive, it will lack midrange response, particularly in the lower gears and the torque rise will be very non linear. 550+ on a 2.5 also starts to become a shade laggy.
If these were normally aspirated or supercharged engines then I would agree the more power the better and just control it on the throttle. Turbo car is a different story.

Everyones idea of acceptable response is different. My take on it is that for road use, full boost before 3000rpm is ideal. Full boost by 3500rpm is just about bearable if you don't mind stirring the gearbox, any higher than that and it becomes hard work keeping it on the boil, especially in the lower gears and at lower speeds.
For track use its different, you are continually in the upper rpm band so the lag is less of an issue.
Typically you can get just over 400bhp on a 2.0 with full boost from 3000rpm and close to 500bhp on a 2.5

With what turbo ? TD05 18G ? MD321H ?

Andy is right
Mines got 480bhp/420lbs (maybe slightly more dependent on day to day variation)
This is on a 2 litre and at this level I love it on the road - I wouldnt want less, but anything more on a 2 litre would be a waste of time as it would be way too laggy
I only recently replaced the gearbox - the sti5 one had lasted 8 years - with average power in excess of 380bhp/360lbs (but I dont do drag racing/elvington events as I find them very boring - Track events are much more fun)
The Turbo characteristics make it a bit of a pain to drive on some circuits - like Brands as the power curve just doesnt cover a large enough rev range and means it just isnt quick enough on tracks with lots of bends......at easy to drive circuits like Snetterton its great, and its also nice at places like Coombe........ technical circuits like Brands dont suit laggy Turbo cars..........
I think most people would be fairly comfortable with the power above - I am for 90% of the time

I can say i wouldn't want it laggier than the 18g myself. It fits in with Andy's guidline criteria. 1 bar about 2900 and full boost by about 3300-3400. That's around the (newage) 390bhp mark. You still get caught out requiring a change sometimes to get a move on. Especially when you come out of a TDi
Sure, a laggier turbo giving boost further up the range will give a less linear more boot in the back, but will less driveable. But that doesn't bother some.
