[R32 Combat]

My car goes for it's first dyno tune on wednesday.:nervous:

I've no idea what to expect, what do you think?
Running @1bar & 1.2 bar
ATW figs, I'm not interested in flywheel figs.

Here is the spec(bearing in mind I've built/tuned it:nervous: :nervous

RB30
ACL forged pistons
ACL bearings
Re-worked std rods
Balanced std crank
Jun 272deg 10.5 lift cams
Highly ported head
Single 80mm throttle body
800cc injectors
Tomei Fuel rail
HKS intercooler
HKS T51r turbo kit
HKS Hi-Power exhaust
AEM ECU
255 lph pump
Std 95 octane fuel

There are a few other things but there not related to engine performance.

Any guesses??

Any guesses??

Is it a nearest the actual figures wins a prize???

A totally uneducated guess would be;

ATW figures @1.2Bar
430BHP to 450BHP
380lb/ft to 400lb/ft

Told you it was a wild guess tho

 

[stuartstaples]

1 bar
410 bhp 370lb ft
1.2 bar
460 bhp 420lb ft
Best of luck Andy. Let me/us know how you get on

 

[plkettle]

1 bar : 400 hp and 460lb/ft
1.2 bar: 440hp and 485lb/ft

 

[matt j]

1 bar : 400 hp and 460lb/ft
1.2 bar: 440hp and 485lb/ft

Just a question and I hope nobody minds me asking but;

Even though it's an RB30 will it actually produce more Torque than Power?
Like I said, not wanting to drag this off topic, just a question.

Matt.

 

[ollam69]

1 bar
459 bhp 420lb ft
1.2 bar
500 bhp 485lb ft and BANG!

Good luck matey

A T51KAI @ 1.2 bar will run approx 450/480 wheel bhp ( no run down bhp boosting allowed) IMHO. with around 460/480 LB/FT of torque , if it doesnt there is something very wrong.

@ 1.0 bar I would say 380/420 wheel bhp and around 400/420 lb/ft of torque

All I can say is i can guess very very well.....;-)

 

[R32 Combat]

I'm sure you can Mark

If I can hit your 1.2 predictions, I'll be chuffed.

I would of guessed higher at 1.2 bar, although Im all Torque :thumbsup:

 

[roadie]

Any reason for the rather low boost pressure(s) other than nervousness ??? (understandably of course). And what peak rpm will you pull out at ??:thumbsup:

 

[R32 Combat]

I don't know the limitations or the fuel pump, thats my main concern. Also, a std gearbox won't last to long with high torque.

I really want 550 lbs/ft(745Nm), but thats alot.

I might up the boost some more and see what happens.

I only have it set to 1bar, and that feels fast enough. Grip is an issue with the way the power come alive.

7000rpm is my limit, but the dyno figs will say if I need more, which I doubt.

 

[Pimpernel]

Andy, are you really planning on only 95 octane? That's a significant constraint on what you can do with the timing.

The Silver Surfer is probably in the right ballpark. Although I don't know what the ACL pistons will handle and AEM is akin to using a 186 processor

The T51 will happily run upto 1.6Bar, especially if you put super unleaded in you tight wad!

 

[R32 Combat]

95 octane is fine, then for extra safely I can run 98.

AEM akin to a 186 processor? They sent man into space with less than that.

 

[TREG]

Grip is an issue with the way the power come alive.

What tyres you using to put the power down Andy?

 

[R32 Combat]

Bridgestone Potenza RE55, track tyres.

 

[plkettle]

i have a SX fuel pump and swirlpot setup for sale, would easy do what you need for that amount of torque...550lb/ft !!!! that would feel quite nice :smokin: :smokin: :smokin:

 

[R32 Combat]

I've got to draw the line somewhere on when to stop tuning. And this is it.:bawling:

550lb/ft !!!! that would feel quite nice

It is lovely to have 550lb/ft of torque.......he he he

HE HE HE HE....your car should be above mine in Torque/bhp as you run the
T51KAI and I only have a weenie T04Z....but I do have the V-cam kit......I start to pull boost @1200rpm....
