What size exhaust housing does it have, as this will make a big difference to the max power.

Steve.

babscossie

I would be careful your gearbox does not die.

Steve.

Matt Baxter

iTrader: (37)

397.8 bhp + 400lbs of torque

i would say that mine is on about on its limit

jemis

To be honest I'm thinking of detuning as it does eat gearboxes I'm trying to find the motivation to change the current one which has 4th & 5th synchro's fubared, 3rds a bit dodgy aswell but i do have 2 spare boxes.

CosKev3

406 BHP/428 LB FT of torque I got out of my T34.63

But it only lived for 6 months running 35psi peak and 28psi held

babscossie

thanks for the spec jemis. i'm aiming for a reliable 400bhp with a 10 grand budget. must inc everything inc transmission. can do most of the mechanical work myself. does anyone think thats possible?

jemis

They are easy enough to work on if you have the right enviroment.

The transmission is the expensive part, there is a genuine ford 909 group a gearbox on ebay at the minute currently at just over a grand which will take upto 500bhp no probs, if I had some spare cash at the minute I would buy it myself.

If your working on a 10K budget you could probably get closer to 500bhp.

babscossie

trouble is its going to be used everyday so must be reliable

ring up a turbo builder!

.63
???????

how would you say that?

just 63 or point 63 etc?????

KSA-Cossie

iTrader: (4)

point 63 m8.

Yura

so, the max bhp for t34 .48(whith 55lbh + std engine + 3"exh + rs500 intercooler) is 350bhp?
What kind of boost can it run?

Lo@der

iTrader: (8)

Well then you might aswell stay on the .48 and ring the most out of it.
There's no point in having .63 lag without the .63 power gains up top.

jemis

Mines already got the .63 on it but I,m thinking of maybe downsizing and going on to greens instead of greys.

LHD220Turbo

iTrader: (4)

use Siemens injectors (Blacks) instead of Bosch, a better injector all round.........and i have a set of 55lb for sale!

RickyLee53

Surely they don't lag that bad?

I run the 0.63 on my civic turbo, I get full boost by 3600-3800 and it's only a 1.6, with a fairly rich spool.

Lo@der

iTrader: (8)

Sorry my mistake, yep if your dropping the power drop the housing size to get the most out of the spec.
You should allways go for the smallest turbo you can for the power your after IMO. Least amount of lag as possible.

Lo@der

iTrader: (8)

Not really bad no, I run one and I don't mind it at all(tho its speced for ALS) but they are laggy'er than a smaller housing size, of course.

jemis

I will see how long it takes to destroy the next gearbox which has been recond and then decide.

I like the power it has now and don't find it too laggy, I think it hits full boost at about 3200rpm redlines at about 7000rpm and holds it well. it is well torquey aswell about 385lb/ft i guess thats whats killing the boxes.

Don't fuck around with re-con boxes, get yourself a Bara/Mullet box .. Give Marco Polo a ring off here, he will advise on the best thing to do, as there is no point in continually ruining gearboxes, you will just get pissed off with the car and loose interest. I was going to run a std box on my Escort, which hopefully will be around the 400/400 mark, but it is just not worth the hassle of changing gearboxes every few months. Granted a Bara/Mullet box will be 3kish, but by the time you have done 3 or 4 std gearboxes with labour, fuck factor etc and buying/ reconning your box it will be roughly the same, except you will always be waiting for it to break and let you down. Build it once,build it right

jemis

I wish I had the cash to do it but in the middle of doing up the house aswell so most spare cash is going there.

To be fare this is only the second box in 2 years and the last one was secondhand (ebay) and a bit dodgy when fitted, 3rd to 4th was crunchy when thrashing it.

Thats why the new one is recond to see if it lasts any better, if not I will have too lose some ponys for now.

Mine made 358 with 26 psi and 373 with 28.5 psi m8.

boXXer

Whos rollers was that on mate? My Stg3 is a bit like a gunship, and wrings the hell out of the dark greens i have fitted, and i only got 351hp(but boost does tail off a bit at the limiter). Are you on dark greens?

Jasesapphy

iTrader: (1)

350 in the real world on greens and a .48, 373 is unlikly on a .48 and especially with greens
