I was wondering which power/torque can you expect with a stock engine, only 803s and straight exhaust ? T3 at 22psi (can it handle more?).

mechanic28

iTrader: (5)

310-320 22psi i would say it is about as much as u can push a T3 !should have a good torque reading tho maybe 330-340lbf

TIFF

320bhp max on a T3........

Trist

Same spec as my old one and it was a very punchy 310bhp and 320lb ft. 2wd

-31 actuator too I guess. -34 would be too much isn't it ?

Twellsie

iTrader: (1)

maybe not Tiff

bigchez

O/T but Tiff were you in Warwick the weekend? Sure I saw that Skoda parked opposite the race course.

Mad Matt

iTrader: (2)

Can you tell us more mate ?

Twellsie

iTrader: (1)

cant say for sure as i have not had it back on the dyno yet, made 310bhp & 336 ft/lb last time, but boost has been upped since then and have been advised with the fueling etc it should be 330 ish

mine is on greys btw

Mad Matt

iTrader: (2)

Ok mate. But I don't know which actuator to use with the T3 at 26psi ? -31 or -34 ?

Chip

iTrader: (3)

rwd or 4wd T3? Seems to make about 10bhp difference.

getting the boost up isnt the problem, its holding onto it, that turbo simply wont flow enough air to hold onto anything much past about 1.5bar really.

320-330 is the absolute ragged edge of what it will manage from what Ive seen.

gingeRS

my old stage 3 saff, -31, 803's and a T3 made 311bhp and about 325ft/lbs of torque

that was peaking at around 24 and holding 21psi

Mad Matt

iTrader: (2)

4WD T3. Spoke with Stu and peak 26psi, holding 22psi will be fine !

Just need to know now if getting the -31 or -34.

Twellsie

iTrader: (1)

that sounds about the same as mine was, its now peaking around 28psi then holding 25psi iirc

You can get a 343bhp from a hybrid T3 with a 60 trim compressor. This achieved a best standing quarter of a 12.892 @ 111mph at Santa Pod way back in October 1996. However, obviously this was on the old benzine super-unleaded 98 RON. Also, this was live mapped on an engine dyno. There is no way you would get this power with a generic off the shelf chip.

Wow, nice results, Mike !

I also forgot to ask if a 044 fuel pump was needed with a T4 pushing 26psi and 803s ?

Twellsie

iTrader: (1)

do you mean T4?

COMEDY DAN

It is always a good option to renew the fuel pump.

Why wait for it to fail and melt your engine at 160 mph, when you can put a new one with a new fuel filter and have piece of mind.

Much Love.

Sorry my fingers went mad. I meant T3 yes.

Turbosystems

iTrader: (5)

a 4x4 60 trim standard t3 will shed the exhaust wheel at boost levels above 22 psi, the thrust bearing will need to be 360 and the you will need a 7 degree cut back exhaust wheel.By the time you have had the bill for this work you may have well bought yourself a modified t34

Mike Rainbird

iTrader: (3)

Hence why mine tailed off to 21psi at high rpm and had all of the above features. It never went pop either .

Tony, he is from Switzerland and so he cannot legally change the turbo at all, hence why it has to remain a T3, as externally it won't look different from standard .

Matt,
I retained my standard fuel pump, as in good condition, these are good for 400bhp anyway.

Twellsie

iTrader: (1)

the wheel hasnt come off mine yet

Mad Matt

iTrader: (2)

Mike if only I could find a girl who understand my "problems" as you do...

I think as Michael told you, yes in Switzerland we cannot modify anything. Or at least without huge difficulties. My car has Koni homologated on it, and it was quite a pain in the ass to do that. So for engine bay I will have to keep the T3, use Roose motorsport black hoses, and its about all what I can do.

I cannot even put grooved brakes, not even thinking of changing the disc size.

This is for a road legal car in Switzerland, but we have the technical control every 2 year so in the mean time (if you don't get catch by police) you can use during 2 years "illegal" parts like what I will do, with brakes, exhaust, and so on.

Well I will stay with 22psi then, as turbo only has 360 but not the cut back mod. So I will even be able to keep the std fuel pump and use that money for something else.

Perhaps you're driving for economy rather than as if you stole it?

Although I never had any issues with my T3 or T3/4 0.48 a/r, I used to kill T34s with both 0.55 a/r (my Escort) and 0.63 a/r (my Sapphire) on a regualr basis .

Twellsie

iTrader: (1)

economy, whats that?

its been running that much boost for the last 3 years and i drive the car everyday

Yes you did mate.....it was outside my house

let me have a go in your car Mike, i will show you indestructable, lol

Forgot to ask if I will need the "group A" head gasket. For turbo I will just put the 360 kit on it with a small rebuilt, and if it goes bang, then I will get a proper T3 one !

daz1968

I had a T3 from turbo technics, it is a stage 3 supposed to be a front wheel from a T34 so will flow more air and still look standard, maybe this is the way forward for you. I still have to get mine set up however as only just run the engine in.

mechanic28

iTrader: (5)

grp A headgasket is a good idea fella at 26 psi and holding 22 psi and a -31 actuator will be fine!

Mad Matt

iTrader: (2)

Have a second engine there too, which I will rebuild, so might just put the power on the old engine and see what fail first and then put the rebuilt engine inside.

I don't want really to buy anything for the old engine as I would first to get the bottom balanced but got no time to do that yet, so will do on the "new" engine. Will see if it goes pop

POPEYE

same as mike's really apart from mine held 32psi till 6k dropping to 21 after that

Mad Matt

iTrader: (2)

Mike, where can I get that "hybrid" T3 you were talking about which produced 380 of torque (live mapped) ? I don't think my T3 will handle 26psi as it is a quite used unit and it will blow up surely.

Turbosystems

iTrader: (5)

we do a standard looking t3 with larger comp wheel .55 turbine housing cut back exhaust wheel -34 actuator etc etc for people like yourselves who are resticted in mods.
This turbo looks identical to standard externally except it is shinny and new

Mad Matt

iTrader: (2)

Would it be possible to have a .48 version, as I want to avoid lag as much as possible ?
