P.S. What is the full engine, Turbo and exhaust spec?

That's a great torque figure which suggests ports or inlet manifold are the culprit!

[SEG1]

thanks Excursion.
as for the graph, it will be on the way to me on monday ,i was so excited to get in the car and drive it that i forgot the graph!

engine spec
87mm omega pistons
wrc rods
ported head
130 inlet cam
105 exhaust cam
arps through out
710 omex
focus rs plugs
gt2871r 64.
3inch exhaust from down pipe.

might have forgot something

im really happy with the torque

you will struggle to get much more boost into it without having to pull loads of ignition out of it on the .64 housing mate and if you do your egt's will kill the turbo if you dont monitor them mate.

[Excursion]

Is that an RS1800 inlet manifold?

They said they tried to pull lots of ignition out , but something was still restricting the engine.I was thinking intercooler.
How much boost did you run on the 64.?

[SEG1]

Is that an RS1800 inlet manifold?

Yeah it's a high output one.
It should flow 300+ I was told.

[jonyb4]

thats an impressive figure, expecting more or not im impressed

[SEG1]

thats an impressive figure, expecting more or not im impressed

The engine has done under 1000k so it will be on low boost for a while.
There is still lots of bits that need to be done before I attempt to run max power.

Still running in really

[jonyb4]

then even more so what i said

its not even 100% and its ready to slay evo's!

congrats on the figures,
hope you find your restriction soon

cheers mate.

now im really thinking its the crossover pipe

need to start eliminating them one by one.

the problem is not the crossover pipe or your intercooler it's 100% the exhaust housing .
i ran mine upto 20psi and got nothing but hot air! and the ignition we had to pull out was unreal.
what did your mapper say?

p-s dont forget your turbo has the same compressor as the gt30 turbos ....

Mate, Ian was speccing a .64 housing for my build even when my goal was 450bhp. He said .64 will give better response, or I can step up to the .84 to keep under bonnet temperatures cooler at the expense of raising the boost threshold by 400rpm. This was in a 50 trim GT30 BTW. I have since gone for the .84 housing as it'll be needed to get well past 500.

Does the 2871 need the .84 in your experience? Rather than changing the housing, maybe a 2876 would be better here?

It's not that then, it would have been if it was the SO or something.

was ian speccing it with a .64 t2 housing or a .63 t3 flange housing ?
no gt30 will ever do 450hp on the .64 housing the back pressure would be astronomcal.

Here you go mate - "Housing A/R. If we use the GT28 turbine with a 0.64, it’ll spool very strong but not exceed 380HP. The 0.84 is about 400rpm laggier but does over 400. If we go with a Gt30 56mm wheel, we can run a 0.64 that will fall between the GT28 options and make more."

So it was a 56 trim...I didn't think the flange made a difference - you just choose the one to suit your packaging requirements (spec sheets are the same regardless of flange type)? It is a V Band housing.

i have no experience with any of the v-band housings.
but the t2 .64 housing is comparable to a .48 t3 housing if you follow and the .86 t2 is more like the t3 .63

so what i need is the 84. housing then?. im only running 16 psi

i have two mates running the same turbo on different engines and they see 1.7 bar all day long and their both using 64.

its quite annoying . why does this happen with a zetec?

no a .86 mate, like i said you will be able to run more boost but it wont make much power and you will be pulling ignition out like no tomorrow

who mapped it and what did they say was happening?

Jamie@Jamsport mapped it.he said it would make any more power and he tried to pull out loads of ignition , but there was something restricting the engine. He said the it peaked off and went flat.

you would only pull ignition if it was detting and if was detting then its the housing mate.
if you were local i would lend my housing

p-s a more efficent inlet would give more power at the same boost but if you try to run more you will still have the same problem .

thanks mate.
do you run the same turbo then?

i will be looking for a new inlet in the future .

yes mate and i hit a brick wall with the .64 housing great for a road car tho, i ran a 12.7@ 116mph with 16psi changed to the .86 and 19 psi and pulled 123mph terminal .
car was running 1.8bar at the end of last year but never ran it on the 1/4mile ,will do this year tho.

wow not bad at all .
so with the .86 it doesnt make that much difference.as in 3 more psi.
i wana run 1.7bar!

no mate it makes a massive differance 7mph in such a short distance takes a lot of power to do.
i was only running 19psi as that was max my actuator could hold.

standard 2.0l blacktop

ive been collecting parts since oct when i took the RS off road.
main thing was too get more boost for this summer as i was restricted to 16psi.
got myself a megasquirt v3 ,new inlet manifold made by crazycage(gary), .72a/r external wastegate housing with a tial MVR and a single pass intercooler.
also got a new alloys and some ap brakes

just need to fit most of them and up the boost with good results hopefully.
16' compomotive cnx



Ap cp5000

Tial MVR watercooled but not sure if ill be using that feature.

The gt2871r external wastgate housing comes in a .72 a/r


AH custom single pass intercooler

Very nice car and spec

Interesting on the turbo running 1.7bar. I've got the same turbo (hks gt-rs) and run mine at 1.5bar but i've been told its no longer efficent above that. All on a sr20 btw.

[jonyb4]

very very nice!

i dont wanna know how hard that inlet was to bolt on
