Average power of a supra, what is it?

...

I think the stock supra actually makes 320bhp.

And if you want to know about tuning, searching for BPU is a good start.

To add a bit more : On this forum, I've never noticed a "stock is best" attitude. The general concencus is : tune it as much as you can. BPU gives about 400bhp I think, but single turbos give much more.

Yep sorry your right 320.

So i know that the standard Supra knocks out 280 bhp, but are owners happy with that? How easy are they to tune to a high power level then? Does an exhaust system and induction system add much to these machines? Or is increasing boost the way to go?

Have we any monster power Supras on this mans forum?

I know i could use the search button but i am new to here with no clue about tuning Supras,and this may be a good way to meet the solders:D Do you also get traditionalists who frown upon touching the original model i wonder.

Mine is std TT J spec

actually puts out approx 320 bhp in stock form - the 280 bhp figure was a ruse in Japan for some reason I forget.

I dont personally like modded cars the buggers fast enough for me as it is

but each to their own and there are some superb cars in this club.

More importantly there are some fabulous people in this club as well.

i started stock around 300bph,(with age losses accounted for) then went bpu, about 380ish, then hybrids about 450, now single at 520 but with mods to 700, its a scary road to take this modding mullarkey:D but such fun;)

J spec is 320bhp?

I thought the UK spec was 320 and the J spec was in fact 280?

when you get used to the power you want more.But you need deep pockets.

There should be no age related power loss provided the engine is in good health with good compression.

I've had a couple of bog standard J spec TT's put out 323bhp on the dyno so that's a pretty sure thing to me.

Changing the exhaust and decatting a J spec is the same thing as increasing the boost as the wastegate can't keep up and as such cant regulate boost... a restrictor ring is placed in the exhaust system to limit boost to a sensible level. This (and some other basic mods) is enough to see 390bhp and is termed as 'BPU'.

The 280bhp was a gentleman's agreement that all the big Jap car makes quoted but then ignored Do a search matey its been covered in detail many times and quite interesting

Sorted, I have more power than I thought

There are a few (very few!) here that keep them standard. The temptation to modify is great since it's so easy and cheap to get an extra 80-100bhp out of them (not to mention the increase in throttle repsonse, etc).

The problem is, once you do that you get the bug to do more (big intercoolers, injectors, ECU's, etc), the costs to modify increase exponetially with the power targets, ie:

300-320 bhp = stock

380-420 bhp = BPU (about £800-£2000 dependant on the condition of your IC or UK/jspec)

450 bhp = hybrids (about £3500 to do properly)

550+ bhp = small single (starts from £6000)

850+ bhp = big single/twins (£25000 upwards)

...

May i assume that a J car imported has a restricted top end of 112mph? I remember it was that way with imported 300ZXs.

Yep, just needs a little unit added to remove that

Blimey, this old chestnut hasn't come up for a while. It used to be regular occurrence.

As said above, at one time the Jap car manufacturers agreed not to make cars for Jap domestic market that were over 280bhp. They didn't stick to this agreement for very long but for several years after they continued to quote their high power cars as only making 280bhp.

Many cars which make in excess of 280bhp, besides the Supra, are also quoted as only making that figure.

ive been arround here for a while but one thing ive never learned... what are hybrids?

replacements of the origonal turbo's?

For a proper hybrid (commonly known as stage 3); They're stock turbo's with the compressor & turbine housing ground out to increase the inducer & exducer size, plus a new compressor and turbine wheel made of steel with a larger inducer and exducer with larger scroll area.

Essentially it makes the turbo more laggy but capable of more peak power.

Yep, replacements usually with some trick bits added...

So do we have a possible convert from the Italian side or are you trying to wind things up a bit Spider?

Hmmm, not sure about the housings being ground about. I'm sure some (lots?) are just straight same-size steel replacement wheels.

I've noticed that everyone that has hybrids claims they're "Stage3" but almost none of them know what Stage 3 actually means.

Does anyone know somebody with Stage 2 or 1 hybrids?

More importantly, would they admit it?!

Do you think they've all had this claimed specialist engineering work to make them a larger capacity? Or have they just had the broken bits replaced with steel wheels?

I know what I think.

No seriously though, all hybrids seem to be "Stage 3".

So where is stage 1 and 2 then? and what would they consist of? Fully agree with you though, it is nothing more than a marketing term..

Envy Hybrids are always Stage 3 iirc, same goes/went for JPS ones too i think, but i have never really looked into Hybrids....

:sigh:

Yes, but that's my point. Do any of these sellers say what Stage 3 actually involves?

If not then it's meaningless, isn't it?
