Comparison of Single Turbo RWHPs

I knocked this up to compare three single turbo Supras that have all been Dyno'd at Marlin Motorsport.

I know which one would by far be nicest to drive:)

Nice Post Jake...

Very interesting to see the curve differences...

I know which one would by far be nicest to drive:)

Which might that be??

Jakes spools beautifully, defo the one I'd go for:)

Suprafan2 will be wheel spinning its nut's off....low power, low power then bang big power.

Yeah i was thinking that... I do like Jakes Power curve.

And you'd be surprised with my mods.. that i dont really spin that much....

...but Andy's makes a shed load more power.

Shame you can't have both, isn't it

Which might that be??

Jakes, when i went from the T88 to the GT4088 i lost about 100peak bhp, but the way the smaller turbo delivered its power made for a far faster street car, id never go large turbo again for a street car,

Imo have the best of both worlds, small to mid size tubby with Nos for that extra top end punch if you come up against something real fast.

Jake, whats the use if you can't use that power and put it to the road on everyday road conditions.

You'd probably leave most Grande powered singles round a track.

Hey Jake any chance you could add in SimonB's T35R vs. T67DBB??

That would be most useful

While you're making 300HP at 4000 rpm and really motoring the others would be losing so much time in a roll on.

Hey Jake any chance you could add in SimonB's T35R vs. T67DBB??

I'll be guessing the numbers from the graph but it should be pretty close. You don't happen to have the data in text/Excel format do you?

Those are RWHP, right?

Great info guys.

Needs to be a sticky in tech i reckon

Great info guys.

Well done Jake.

I started doing this but soon realised that unless Ian and Simon's cars are making over 600RWHP and 550rwhp respectively these figures can't be right.

If they're Flywheel figures the comparison is meaningless.

Interesting Jake, I've attached a copy of my dyno of a GT3582R, lower line at the wheels upper line estimated flywheel.

Sure.

Ah...think they are estimated flywheel...I know Ian's powertrain loss was only 8% but most seem to think the manual loses 15-20%!! (I think you all need to put some air in your tyres lol)

Ian got 580RWHP....http://www.mkivsupra.net/vbb/vbpgimage.php?do=full&p=1497&d=1142339607

But either way can't give you a graph

Not with racing drivers and a well set up car.

No you haven't

you need to be careful you are comparing apples with apples guys. All manifolds should be the same material etc, preferably the same dyno.

No you haven't

Have now, the image was too big to attach

That looks interesting just comparing it to my dyno result Just out of interest you labelled yours as GT60 was that your PHR stage 1?

I thought :-

PHR Street turbo is GT60

PHR Stage 1 turbo is GT61

I thought :-

 

PHR Street turbo is GT60

PHR Stage 1 turbo is GT61

Just though he may have meant a GT60 series turbocharger?

I thought :-

PHR Stage 1 turbo is GT61

Both are the so called GT60
