[R32-GTS]

What other internal engine work has been done on the car?

hi blitz. has Arias pistons. N1 piston rings , Pauter rods and HKS head gasket.

Peter.  I want to run it that rich just to have a bit of a buffer zone as i will give it a hard time and just want to make sure its safe. Id rather sacrifice some hp and just make sure it doesnt ping. As with fuel thats the most that pump is gonna give at those afr's. Fabs gtr went about the same hp with a single 044 so im going to use 2 with a surge tank . Cams it is using are HKS 272 272 step 2 10.2 mm lift which isnt huge lift as they go up to 11.8mm on some. . As for target boost pressure this turbo should be in its efficiency at 24-27psi so thats what im heading for. Also lift the limiter from 8k to 9k when it has a fuel system to support it.

Why do you think it is the fuel pump? Have you monitored the fuel pressure on the dyno? If the pressure drops that means the pump is running out of flow capacity. With 13.8 volts via a relay and direct to battery connection the single 044 should have more than enough capacity to handle that sort of power.

[R32-GTS]

Hey sydneykid. Its got a HKS reg running 2 bar base pressure and comes onto boost hits around 4bar and holds it all the way. Oh and it has 13.8 volts with a relay and cable striaght to battery.

ok cool

thats a pretty big buffer but ha each to there own and rich is safe

so by way of a the 800hp turbo at mid 20's psi with high lift cams and spinning it to 9000rpm you must be think around 600rwhp then at a guess.(or did you have a target in mind)

and if your going to spin it pretty hard what oil pump you using out of interest?

pete

sorry to hear about the box

[R32-GTS]

Thanks yeh box is a bummer hopefully new one in by weekend. Im happy where it is at the moment as it feels nice to drive with not much lag and good top end. Im thinking in the mid 20's it may go near 600rwhp but until it does that i cant say what it will do but it is a good sign to be making good power at lowish boost. Its running a JUN oil pump.

[GTS-t VSPEC]

Well done Simon, it gives me more confidence to follow the same route to get my 600rwhp too. I'll get two 044's setup for mine now:D

[Gav]

Nice work Simon

Did you spend much dyno time playing with cam timing?

[R32-GTS]

Hey Gav. Havn't had time to play with cam timing yet as its only had a ten min tune.

[Gav]

All good mate - happy for ya

[R32-GTS]

Now just to get yours going !

[Gav]

It's in the wind digger - just like my divorce when Mrs Gav finds out my crankshaft costs the same as a small country villa in Bulgaria!

[R32-GTS]

Haha nice. I take it your buying one of the Jap billet items ?

[Guest DIRTgarage]

I hope you have a large cost-effective supply of gearboxes...you'll need it

[R32-GTS]

Haha why do you say that. Im hoping it was a one off breakage !

[Wazz]

10 minutes tune got you a 590rwhp reading from a 800 hp turbo on 16.5 psi?

whos the tuner.. i might have to use them

[R32-GTS]

Says 519 to me dunno where you got the 590 from but hopefully should get there soon. And power fc comes with a base map . With the laptop software does not take long to tune at all.

[Wazz]

err woops my bad lol i might listen to the next person that tells me i need glasses

either way.. still ****ing awesome for the amount of boost used

[Remix-]

Congratulations! A long time in the making, but most definitely worth while

[SimonR32]

I hope you have a large cost-effective supply of gearboxes...you'll need it

simon doesnt learn....

he went through about 8 or so rb20 boxes and still didnt learn

how many gtr boxes have to be killed :uh-huh:

car goes very nicely, was shotgun in it same say as the dyno run... can't wait till more boost and better tune

PLUS A DECENT GEARSET

[StageZilla]

hey simon nice results :uh-huh:

pitty you sold me the spare gtr gearbox you had haha

goodluck and hopefully u can take me for a spin when its sorted to show me some single turbo power (and maybe ill convert mine to single haha)

cheers
