What's your boost threshold?

[zukgod1]

The t3 super 60 isnt that big....guy run it on turbo 1.8-2.0. It would be way too small to run on a vr6. I think it would be a little big for a diesel but with a proper pump I think it could yield some nice power.

Sure it could, At 4000 rpm and up.. If that's where you want to run fab it up and go.

Whats the disp, hp & tq @ RPM numbers from the engine that turbo is off??

2.7 V6, 190bhp at 4000rpm, 325lb/ft at 1900rpm

I used to work on these vehicles and they do come in nice and strong so I am hoping the turbo is on the small side in order to increase torque due to being a 4x4.

the fact that the turbo allows the engine to produce 325 lb/ft @ 1900 rpm shows you how well the turbo spools down low, and that its a VNT.  i think that this turbo would be well suited to a 'hopped up' 1.9 diesel engine.  the lag would be comparable to running a K24 i would imagine.

If this is used on a 2.7 ltr engine, is there a way to figure out many CFM of air is running through the turbo at 1900 engine RPM?
Then see what RPM the 1.9 motor has to spin to make the same CFM.

The only problem I can see with this theory is that it might be related to how much fuel (load) is applied. There is more heat generated (expanding exhaust gas) from a 2.7 than a 1.9.

Am I over thinking this?  :shock:

I will be runnning a 1.6 bottom end though so even worse......

I am going to give it a go, if it sucks I will put the T3 on there. I am sure Land Rover run them very lean for emissions so with a bit of smoke and the ported head etc I hope it will work ok.  :lol:

See my project thread.

Im running a S1B switzer, with no wastegate on a 1.9 AAZ and it will start to spool at 2000rpm and will peak at 30psi at around 3800rpm but i had to modify the pump to get it that high otherwise it would only hit around 8psi. Its good around town as well as on the highway were it will sit around 3psi crusing

What vehicle does that come on standard? I would be happy with that sort of spool range as I think the top end will be worth it.

Can I ask what you done to the pump, or do you just mean fuelling adjustments?

[UnderPSI]

A 2.7 flows 6.25 lbs/min at 1900 if it had 100% volumetric efficentcy. A 1.9 will flow the same considering 100% ve at 2700.

S1b Schwitzer can be had new for around $400.

[barrygti]

So it's not un-reasonable to expect full boost on a 1.6 at around early 3000rpm range??? Perfectly fine by me if it will then hit 200bhp!!  :lol:

[UnderPSI]

A 1.6 would be 3200.

[barrygti]

Yep that's what I just worked out too, but I would assume that's full boost if the peak torque of the 2.7 is delivered there, so that would mean it should start spooling earlier with full boost(dependant on level of course) at around 3200rpm, hopefully continuing to around 5000rpm will give a nice enough power band.

i think the only way to know is to try it.  u could plug numbers all day and get an idea of what you need but until you try it you won't know, there are so many different styles and sizes of wheels.

It's a T3 Super 60 actually.

[TurboJ]

A Super 60 will support around 300 hp on a gasser 2.0, and that means it should be able to make 200+ hp on a diesel of the same size with little trouble.

As for spool-up, on my 2.0 Saab I got a T3/T4 since a super 60 would've been too small. Even the T3/T4 gave full boost at 3000 rpm.
The difference in spool-up between the T3/T4 and the stock T3 wasn't dramatic, however the effect of spool-up definetely was!
Since a normal gasser T3 works fine on IDI VWs (experience from another guy), a super 60 should be just just as good, given the fact that even with a T4 compressor the T3 does not have that much slower spool-up vs a standard one.

Looking forward to your results.

just like everyone else here I love BOOST!!!!!!
