[SATO GTS]

all's i have to say is

F'IN AWESOME

[fatz]

yea kyle has been for a spin in it

[ferni]

adjustable cam gears with a proper tune should help boost come on earlier.

[fatz]

yea cam gears some cams and some injectors are next on the agenda

[joh21m]

off topic...wen did autosport get a dyno dynamics dyno? have they got rid of that old one they had in the ground?

fatz,

I've been looking at a few compressor maps (GT35 .50 a/r)

It appears if you run 20psi you will run over the choke line with anything over 7000-7500rpm on a rb26.

Playing with airflow figures from the 4ltr I can see (i think) why this turbo was selected.

Thats providing I know what I am doing. Still getting the hang of it.

Going by what I can see, I would expect power to either flatten out (lack of efficiency = hot air) and or boost to drop off at the top end. It will be interesting to see really what happens.

Cubes , would be very interested to see the compressor map of the GT40 comp in .50 E cover . Any chance of posting it ?

Thanks A .

who knows but hey ill try

dyno dynamics..

could be my fault i just assumed thats what it was... (i dont know shit form clay when it comes to dynos its only the second time i have been near one)

but here is a more accurate test

down the main straight a oran park racing with a gibson hr31 which has 270rwkw he pulled about 3 car lengths on me (he weigh in about 200-300kg less)... then at the end of the straight he hit the breaks and i almost went up his bum man what a rush driving along side those beasts loved it...

[fatz]

oh yea i dont really want more power than say 270

just want it over a large area so any advice is appreciated

I was looking at a GT35 .50 comp map.

I am a little confused at the moment as the GT35 uses a GT40 model comp wheel.

I've checked out a GT40 comp map with a .58 comp cover which is as close as I can get, the map is much better suited and allows 20psi right up until 8500 with around 55lb/min worth of air before it begins to choke. BUT this comp map was using a slightly larger comp cover so choking may begin at around 8000rpm.

Garret don't list a GT40 with the ford specs (exhaust a/r & comp cover), that doesn't mean it isn't a custom job.

Garret do list a GT35 with the exact ford turbo specs (.50 comp over and 1.05a/r exhaust a/r). Being the GT35 uses a GT40 model wheel could it be this?

If you were to use the GT40, 20psi & an RB26 that were to rev to 10,000rpm it would completely use the comp map (max 63lb/min).

An RB30DET would need 8500rpm & 20psi to flow the same air.

I'm sure it will keep making power as it goes in to choke as these little stock T3 turbos must be constantly in choke from anything above 5500rpm lol.

Too hard basket.

Discopotato, the pdf can be dloaded from Garrett.

Fatz... If you can get the rev's/airflow via cams I can see 340rwkw..

[Cubes]

GT 40 & GT35 COMP.

GT40 exhaust & comp cover specs don't match that of the Ford.

GT35 exhaust & comp cover specs do.

Then there's the GT35R which I haven't posted a compressor map for.

This is the one of choice.

[fatz]

by all acounts it should flow some more

who knows....the boost went to 1.2 bar at 5000 rpm it made almost 270 then before greg stoped to turn it down abit

ill get a power fc and let greg loose with some injectors ect and some cams athen we will see what it can do

dont really know just happy with it as is at the moment

Hiya, just wondering where you got the Z32 AFM=> 80mm pod filter pipes. Did you buy them or have them fabriated?

Thanks,

Penfold

[fatz]

air flow meters are just stock gtr

pipe into turbo is a greddy t51r intake

Joel its not difficult to be confused with Garretts PDF . I think the maps of the GT32 and GT40 may be describing bush bearing turbos . In that list GT30R and GT35R , I think the "R" denotes GT series Ball Bearing CHRA . If you looked at the GT42 it shows the optional BB CHRA .

With the comp covers the maps don't tell if they are TO4E or TO4S . I know for sure that Garrett did the E covers in .50/60/70 ARR's where the TO4S ARR's are all over the place with odd ball no's to suit diesel apps .

The 50 E cover would not have any meat left over with an 82mm compressor in it . Ford would have looked into the maximum flow of the cover and probably decided it was enough for 240KW (crank) with effectivly the 4 psi that makes it to the inlet manifold . Brett tells me that 6psi leaves the compressor and 4psi leaves the intercooler .

I reckon looking at the large 1.06 ARR turbine housing and adequate ? comp cover Ford were trying hard to have little restriction on the exhaust side , and just enough inlet flow to get the power rating .

Garrett and Ford would have the compressor map for this combination but getting it out of them would be difficult .

As an RB bolt on these should be pretty good , its just a pity Garrett haven't done the .82 turbine housings as well .

[Cubes]

It will be interesting to see the actual numbers.. 5psi doesn't sound like much but it may very well prove to give a nice increase in power with the ol' rb at low rev's.

I'm about to select a comp cover for my turbo so I need to do a bit of reading up on these TO4E and TO4S comp covers.

[fatz]

so all you turbo gurus out there

can i just stick the bigger from housing on?

would it be a complete waste of time or would it make more power

or should i justget some cams and gears and be happy with whatever i can flow at around 1 bar

[fatz]

full boost really hits around 4800 now if i can get that doen to 3800 i would be mighty chuffed, is it posible to make it happen

im thinking some tome b cams (says they spool up a large turbo quicker than standard)
