3576 torque curve

[Dat111]

hey guys!! hopefully somebody can tell me, when the 3576 starts to build boost an then it runs out of steam) I cant really find much on the internet. 

[k31th]

it depends entirely on two things:

1. Your mechanical setup with regard to boost control

2. Your tune etc.

 

Any dyno sheet showing "boost" will show it as you desire.

Did you use the search bar? I typed in 3576 and this was on the first page

Hey mate, sorry been pretty busy but I’m here now so I’ll address a few areas to help you

 

First up as I’ve told you before without any negativity but DynaPack Dyno’s read exceptionally high, always have, always will due to their retarder systems. That’s fine as long as you start on one and measure each gain throughout your journey on the same one to see the real number difference which is correct… it’s just the outright numbers never align anywhere close to other brand Dyno’s which can be pretty close to each other! 
 

Next up so you can see where I was going on the below tunes I’ll explain this for anyone who doesn’t know …. A factory FG ZF tailshaft can and definitely will snap even on the Dyno when torque is generated at a point past what the shaft can take… this figure is not hard and fast but I know it’s capable of 8psi steady state but not typically more than 10psi ( use stalling up at the lights as the example here )

 

Next is the factory FG ZF flexplate has a weakness attributed to the factory x6 bolts that secure it to the crank shaft to “walk” loose with torsional rigidity loss at around 380rwkw or 18psi… the harder and faster ( or more aggressive ) the tune is the quicker this will happen and you’ll see why I stop where I stop for these reasons  
 

So your 380 ish RWKW @ 14psi is probably closer to 340rwkw honestly. Here is a FG F6 sedan I’ve tuned with the factory GT3582 onboard and typical mods that you have but 18psi up it’s arse on 98 fuel. This vehicle didn’t have an aftermarket market tailshaft or Flex plate so this was as hard and fast as I felt comfortable ramping in the boost. Replace the tailshaft and if I pumped in another 1-1.5psi it would of clipped 400+rwkw on 98 which is about all the GT3582 has as an efficiency peak flow map (19-19.5psi ) and as you can see from the below this tune came out beautifully, all the right curves in the right places  

 

 

 

Now here are two FG Turbo ZF sedans with Genuine Garrett GTX G2 3576’s on board T3/5bolt/1.06 housings with Genuine Garrett 0.60 comp covers 

 

This one was stock Tail shaft / stock Flex plate

second one had Carbon fibre tailshaft / stock Flex plate 

Both have typical mods as you, both on 98 fuel All run in 4th gear etc etc 

 

 

 

This one stock shaft/flex plate 

 

 

What you can see is if the tailshaft is addressed you can put in a bit more sooner, if you have a Flexplate upgrade ontop I could of pegged a nice 20psi for instance and been into the 400rwkw zone without a doubt on 98 fuel. My honesty thoughts from tuning a large variety of FG’s with different turbos is the fact that yes the GTX of any series (76/82) is vastly superior to the GT 

The GTX G2 76 I would class the ultimate street turbo matched up to a ZF vehicle for response…. But… up around 400rwkw with the rate of aggressiveness the GTX G2 3576 can deliver on full send ramp in boost will and does destroy the driveline in a faster more obvious manner than say the GT series or GTX G2 3582 can. 
 

Some food for thought here…. Bang in a tailshaft, flex plate, HD half shafts and a GTX G2 3576 vehicle can be electric fast too a point where the input shaft start’s hating life next. This is just something we don’t flog out at this rate with other turbos in this manner unless being intentionally abused, the 76 just has more sooner which makes for a fun turbo. I’ve seen many workshops pump out over 400rwkw on the G2 76 and upwards of 450rwkw on E85 !! 
 

Assuming you have a full built driveline this turbo can walk in 10 second 1/4 mile passes as we did back with the Gen 1 GTX3576’s  

 

Out of the GTX G2 3576 & 82 I suggest customers go for the 82 if they’re more budget minded as we can make factory driveline parts last longer than 76 punters as the 76 is a savage beast on 100% ! And typically can deliver higher numbers on the 82 which 90% of punters want ( big Dyno sheet ) 

 

TLDR; 

 

GTX G2 3576 - Aggressive tyre fryer 

GTX G2 3582 - Big numbers on the Dyno 

 

Cheers

450rwkw on E85 from the baby 3576 turbo?

That's more than just a happy dyno. That's a broken dyno!

Clearly you struggle to read as well as use simple search functions 

 

GTX G2 ———— 3576 

 

not GT3576 ….

I thought I did pretty good really 

 

Thread title says "3576 torque curve", first post describes turbo as "the 3576" and I searched the term, "3576".

Where did you get GTX G2 from?

[JETURBO]

Not you Nath 

 

old mate…. Reads link and adds 1+1 and got 450 out of GT 

 

Dherrrrrrrrrrrrrrrhhhhhhhppppppp

Ah ok, I thought it was a bit odd...thought you might have forgotten to prefill your oil filter this morning or something
