There are no problems at all in tuning the auto boxes to 300+ bhp.

Also, the 850 T5 manual and auto both had 225 bhp. The 2001-2005 S60 and V70 T5 in manual and auto both had 250 bhp. There is a pattern here ! only the R models differed in outputs between auto and manual.

Don,

I wouldn't care to hazard a guess as to the auto\manual percentage sales ratios but whenever I have looked around Volvo forecourts, manuals appear as rare as hen's teeth. With the larger models it looks as though in keeping with the intended market most are auto and I would think that their design people married suitable auto boxes to engines.

As Hamish has pointed out the same power unit providing the same power is used in the specific vehicle pertinent to this thread and possibly many others which is somewhat at odds with your late thoughts. Rather than have this look like antagonistic reply, perhaps you could give examples to illustrate your point as it would certainly be of interest to know what models get a lower base power with a choice of auto box.

Thanks, Liam

On the very specific subject of a '99 V70 T5, yes the later Auto boxes will take some more torque, but there is no problem here in that it is not posssible to gain an extra 60 bhp with just a software rewrite.

Nearing 300bhp with that particular engine, you have to fit a downpipe with special cat and a more efficient exhaust from that cat back and also fit the larger injectors from the current 'R' models as you will be leaning out dangerously.

So, no possibility over 275 to 280 bhp with properly written software on that particular engine, but stonking torque in the mid range with a lovely fat curve which really gets you going.

The '97/'98 Rs do have different bhp depending on if manual or automatic
240bhp: Automatic
250bhp: Manual
The 850R manual had the revised stronger engine (fitted later on to the S70/V70 T5) and 250bhp whilst the automatic's bhp was 240 bhp.
One does have to ask the question why Volvo chose to make the automatics less powerful! Anybody?

Don,

Sorry Don but I do not agree with your assertions on power obtainable from my vehicle nor on your leaning out suggestions. These issues have been historically been argued about ad infinitum and they always ended up with bad feelings and no conclusions.

PPC claim +59BHP (= 299BHP) for my vehicle. RICA claim a little more and you by implication believe they are both wrong. Based on my reading of the USA site of your software companies US distributor, your supplier deliberately applies a very conservative tune which rather tends to imply that more is available. Of the three major re-mappers (that I know about) your company claims the least power (by design) but you appear to take the position that others cannot be right and that begs the question, why.

I do not recall you ever having stated what power is available from your re-maps so I am asking now. What power increases are to be expected with one of your re-maps for my '99 V70 T5?. Numbers please because substantial is subjective.

I know that there was a c70 in the states that made 303 whp (i believe) on the 5 speed auto.

However I doubt there are any auto 850/70 cars in the uk making a genuine 300+ bhp.

But the concern with the auto's isnt really with bhp directly, it more to do with torque. This is why the auto tranny ecu\tcu sends a signal to the engine ecu before a shift to request a reduction in torque. However with the greater torque from the chiped cars the trans ecu will increase the shift speed which causes the harsher shift. ultimately, if the box can take the torque physically then the harder shifts are better for it as you have less clutch pack slippage and thus less heat and wear.

An easy way to make the auto cope with higher torque is to run better fluid and an external cooler.

so my view is that the autos are pretty strong if looked after, and should take 300bhp.

Does anyone know of a 850 or 70 series auto that is run at well over 300bhp. I assume it has been tried and tested, if the stock Volvo box can't handle it what do people do? Do they put a auto box in from another car or is there an upgraded/modified box you can get?

Interesting and suprising that only the R series has lower bhp in the auto, I wonder why Volvo did do that. Does anyone know why the R should suffer this fate yet the T5 manual & auto are the same bhp. Can an answer be had from Volvo's pr department?

As im aware the new r cars are all 300bhp (volvo claimed), but i suggest people look at the torque figures for the auto an manual and interestingly the 0-60 times for the auto and manual.

The c70 i was referring to is based over on volvospeed, do a search and im sure you will fine it. I believe that it made 303 wheel hp as i said, but i know for sure it made over 300 at the wheels.

however, dont get hung up on power as its not bhp that will break the box!!

[MikeyL]

i know its not a volvo, but over 70bhp is possible by a simple remap on a ford cosworth engine...

i'll get me coat!
