Ok I understand the conversion but exactly what power/torque u get? Also what tother mods r u running with it?

[Fezzy Turbo]

It's the old rule : Just because it says 195 it doesnt mean you will get 195bhp.

But if someone has gone for 195, I would expect someone with that power to have a chargecooler or very large I/C, hybrid T3, lots of head work, bigger valves, cam. You will also be pushing the std bottom end to the very limit, so for reliability i would have that up-rated to.
The std gearbox wouldnt last long either.

The other problem is the Superchip 195 is not the best for this amount of power, something about advancing the timing too much, if i remember correctly.
It would be much better with a custom mapped chip.

[AdrianFRST]

I've always been told the 195 superchip is a bad map - overfuels at idel and underfuels at the top end.

Remember you'll need an uprated fuel pump with your 701 injectors.

[Fezzy Turbo]

Adrian has just backed me up......needs to be a custom chip.

and yes, i forgot about the injectors and pump.....oops!

[AndyBlackFRST]

I will let you know when mines setup mate.

I have a collins chip in mine, this may be better than Superchips, not too cure yet though.

I have a cossie pump, Beiges, low comp bottom end, stage 3 head, piper cam, 0.5 oversized mahle pistons...etc etc

[bassboy]

Kev...kiddah...to get a genuine 195bhp requires alot of work! like fezzy turbo said, u need head work, hybrid turbo, low comp, etc etc...

in our ERST, the follwing mods were done:

1640cc low comp bottom end (7.95:1 comp ratio)
MAHLE +.5mm low comp pistons
Burton Steel con rods
ARP bolts
stage 3 big valve head
stage 3 hybrid turbo (Cossie 2wd compressor....48 exhaust housing etc)
K&N element filter in standard air box
piper cam
Pace intercooler
veriner pully
turbo systems stage 3 chip
etc etc

and that produced 211bhp at 16psi on the first run and then 229bhp a couple of days ago @ 16psi (195bhp at the wheels!!!!)

and that mounts up to ALOT of money!

about needing the stage3 turbo

i spoke to Burtons the othe day about buying a stage 3 and they told me that the standard turbo is good for 14psi????

so why would you need to go stage 3 for an extra 2 psi???

not arguing just want to know if Burtons know what there on about

[bassboy]

yes the standard turbo IS good for 14psi (both fiesta and escort)...BUT with a bigger turbo, you will get more bhp at 16psi (or [ERRR] figure) then when using 16psi on a small turbo...its all about air flow...hybrid turbos are all about combining all the best parts of turbos together, machining out etc etc all to allow, less lag, more boost and air flow.

my cousins Cossie for example, using a T3 cossie turbo at 21psi, he produced 320bhp...now with a T35 turbo running at 24psi, he has hit the magic 350bhp!

get me?

Its not all to do with psi, it how much air it can flow, bigger housing more air flow @ that psi

[keydoh]

Might be wrong, but if the turbo's creating 16psi worth of pressure, it's the same pressure (and power) just that the smaller turbo will be spinning faster?!

[Fezzy Turbo]

bassboy

Rubbish!!!.......no matter what size turbo u use, if your getting 16psi your getting 16psi and you will NOT get more power from a T3 producing 16psi than a T2 producing 16psi.......the same amount of air is still being moved. But the T2 will be working a lot harder than the T3.

[bassboy]

but then thats like saying y are people in Sweden or wherever getting 615bhp Cossies when running T67 turbos instead of T4's but still running the same if not less boost?

bassboy

P.S not picking arguments...just i always thought the bigger the turbo, the more boost and more air u will move (at [ERRR] given PSI compared to a small turbo)....wanna know if ive been told wrong thats all

Greg your wrong

Psi is the pressure at which the turbo can push

look at the size of a compressor on a T2 and a T3 its far larger and can flow more air the air is at the same pressure but due to the larger size compressor housing there is more volume in it thus more air. so same pressure but more air = more power !

this is the reason bigger turbos produce more power not the fact they can run more pressure !

this is the main reason for creating a t3/t4 hybrid the smaller exhaust housing of a t3 wit hthe larger compressor housing of a t4 allownig the same spin up time of a t3 but being able to flow more air than the t3 compressor housign could !

[keydoh]

pressure is read at the charge carrier, this is what the engine sees, not a T2 or T3 etc... just the pressure. If a King gave you Fiver, and a tramp gave you a Fiver, which would be worth the most?

Both the same, except the King would have more money to give more... (like the T3)

[MadcatCraig]

pressure is actually read inside the manifold on the right hand side of the efi unit ! then to the map sensor this measure the manifold absolute pressure.

[snake]

urm, lol think of it as blowing through small and large pipes, both pipes same psi, the larger pipe will shove more air through it at same boost, T2 gets rescrictive due to size, so simply loppin on a t3 will produce more power at same psi. Adverse effect to this is that it needs more rpm-increasse in lag, also something to remember is the heat the t2 will create as their is more heat created by the t2 than the t3 at that same boost which is why t2 is prone to crackin, also less material to soak the heat up. lol, aint been up long but makes sence at the mo

[keydoh]

snake:
the pipes are the same size, not in the turbo (i agree) but the charge carrier, manifold engine are the same whatever turbo is fitted. I'm no expert, just working it out with a bit of common sense.

If you have two pumps, 1 twice as powerful as the other, both pumping water around a system at the same pressure then the same amount of water would pass which ever pump was used!

[bassboy]

the way that i see it, and have experienced...when running the standard T3 turbo and intercooler on the ERST, we were producing 190something odd bhp...now with the stage 3, and pace inrtercooler, gone over 220bhp...and that was running the same boost

with the Cossie, ran 24psi boost...hit 323bhp on PE's rollers, with the T35 added, we are now hitting 343bhp

keydoh, u are right about the pumps, but u cant think of it in that way...in those terms, one of the pumps has to be bigger (a bigger turbo will flow more air/as more volume)...then, when this is flowing at the same rate as the other one, there will be more water flowing at a stronger rate through those pipes right?? (talking about the bigger pump)...considering the pipes remain the same size from both pumps...

ya get me??

bassboy

[snake]

if u look inside the actual turbo, the t2 is s**t loads smaller than t3, so the restiction is inside the turbo itself, pipes were an example, i wasn`t talking about the inlet tracts etc, i was on about turbo size.. u phisically get to a point when the t2 is just too small to flow serious amounts of power.. Above 170/180 bhp the t2 is too small imo..

[keydoh]

OK, I can see the point that after a certain boost pressure the T2 is no good (due to is size), that I know.

The rest I'll think about, because I'm not sure...

[snake]

rest of what lol

[oriont]

just a quick explantation


take a garden hose at 1 bar of pressure
take a fire engine hose at 1 bar of pressure.

the later is about 10 times bigger in diameter.
both are producing the same discharge pressure but which will have the most flow.
its not hard so ill leave the answer to you lot.
oh the same principle apllies for air.

thanks

wahoo i was correct about something

that I understand, for I am not a simpleton. When I read the pressure the turbo creates, I measure it from the dump valve.

Pressure inside the turbo is not measured, or if it is where...

come on, let's make me understand, with the number against me I must be wrong?

[MadcatCraig]

on the compressor housing of the turbo there is a small brass takeoff with a small piece of vac hose that comes off it and goes to the amal valve

a similar piece of hose goes from the amal valve to the hose conected to the airbox/cone this can then tell the difference between pressure of air goign into turbo and pressure turbo is spinning air too

this is also conected to the actuator (this vac hose system) so can control the boost by increasing or decreasing air pressure aplied on the actuator spring/shaft

[keydoh]

so that's different than the pressure read by the boost guage?
