Max boost-bhp T36 Siemens 55's
Hi All,
Bit of advice needed.
I have just got a new TT T36.63 from tony at TurboSystems, (thanks tony ) to replace my broken T34.63, anyone know what safe boost-bhp i can run with siemens 55's?
i have Ab07 inlet cam and standard head.
Cheers

mine is running 55lbs and a t34.63 at 32psi
it made 402bhp (if you believe the dyno)
standard cams and bottom end wrc head gasket been like that for 3 years with no drama but i think the turbo runs out of puff at the top end

dissmarls thats the setup i had until the t34 dropped a turbine blade, anyway i'm a bit slow atm having spent the last week trying to remove a snapped exhaust stud with head in situ which i have finally done.
So..
Tony with your infinite wisdom could you give me a rough idea of a safe boost limit with the T36 and siemens 55's, AB07 cam, standard head, 7.8 cr please lol
Much appreciated.

Well I had the same spec and Tony told me 2.2 bar so I thought about that for at least 30 seconds and then run 2.6 bar with 1,9 held and I trhink you will find its a tt36.55 and on a standard head it will surge a tad at low rpm in 4th and 5th but overall a very good replacement over a t34

Thanks for the replies everyone, Jay i got confused when tony said that i need a .63 i thought it was exhaust housing for 440bhp lol, on the TT card that i got it says .63 A/R and part S241 so i guess that must be the compressor housing then, didn't know a smaller housing could make that much power, cheers for the info.
Tony can you clarify that i have a .55 exhaust housing because i think i might have screwed up when i sent my old chip back for a new one...

I didn't think it was possible for a t34.48 to produce that amount of power

Engine is standard only a Group A gasket and standard bolts just as cosworth intended. Only difference is the turbo has cutback blades which makes for a little more lag.
Dyno was a DD and they specialise in jap stuff and they where shocked too.
Search my posts and you will find the graph.

I thought 55lbs where an alternative for Bosch greys but apparently they're good for 450bhp

Ah the penny has dropped that would be why Stu said he could tweek the map for more fuel.
So on that respect i guess 55lbs will do more around 440 bhp so i have been corrected sorry.
Tony if you smell bullshit you have a far better sense of smell than me
It might not last very long but who cares

2.3 bar peak
please remember this is on a T34.48 which started life as a GrpA turbo with a 34mm restrictor. I then changed the front housing for a std escos one.
This turbo will produce more power than a std 34/48 due to cutback blades which is why I have a touch more lag.
when is was on the dyno it was pressirising the cooling system due to a failed head gasket.
I knew this before the dyno due to cylinder leakage test which showed 60% on number 3 cylinder.
I have since done the gasket and still feels strong.

Could the head lift a bit on standard setup at 2.3 Bar? Mark originally thought mine was at 2.2 but I actually didn’t have the correct pressure relief on my expansion tank, it was fine after.
I don’t know how high boost we will go on the new stroker?

The t36, sounds very interesting, however there are many variations so I was told by one tuner, so be careful,go through Tony for sure.I remember when Jay had his and Big Steve (cossie4i) had these turbos a couple of years ago.

All I know afr was around 12.5 which is really as lean as you can go imo. Stu did say he could add more fuel for top end to get it a little safer but it is only at that rpm for second's so I wasn't that bothered.

I think they work out how much fuel is needed for 2bar and then just allow the ecu to keep adding the same amount until the rev limiter once the map sensor is maxed out. End up running rich at the top end for safety.
One of many benefits of going aftermarket ecu is you can use 4 bar map sensors, I’m going to be using a Bosch 4 bar map sensor on my next ecu and it will fit in place of my air temp sensor as the Bosch map sensor can read pressure and temperature

You don’t need aftermarket management to do this

You can do a 5 bar on the Weber, but my experience of it is that the ecu is very limited in resolution so they dont actually drive very well on it, there isnt enough breakpoints to spread that pressure scope.
