Dyno Resullts (Single turbo 26)

[R32-GTS]

Just for those who are interested. Got a dyno readout from yesterday. Rb26dett running single garrett t04z and 272 cams at 16.5 psi boost. Once i get a proper fuel system sorted can put in some boost and see what it will do.

needs a tune - what's with the jumpy A/F's?

nice curve though, how's the lag?

[R32-GTS]

The af;s are pretty straight except up top the fuel sytem cant keep up and it starts heading towards the 12's. Id rather have it 11-0-11.4 all the way across to be safe . Its really not laggy on the street.

Jumps to 260rwkw pretty hard. Wheeeeel spin

[R32-GTS]

Yeh it killed stripped 3rd gear last night. Not impressed.

[Cubes]

Did it strip during acceleration or a quick grab of the gear?

[R32-GTS]

Quick but not stoopid change from second into third.

[Wazz]

so how similar would this be to the HKS t04z ? both are ball bearing are they not?

[R32-GTS]

They seem exactly the same to me except the HKS has its own customised compressor cover and exhaust housing. The core is the same.

[Wazz]

so both are ball bearing? wat size exhaust housing have you got? i know hks offer 0.61 .87 and the 1.something

[R32-GTS]

HKS have .61 .81 and 1.00. I got the .81 and yeh there both ball bearing

[wrxkilla]

Great work

cant wait to see more tuning and boost!

go hard!

[Butler]

hey saw your car at the sauwa dyno day! beautiful car that sounds absolutely mean! congrats on the result and cant wait to see more power!

[pnblight]

nice to see you getting there simon, you must be happy to have starting to come together

Why you want to run so rich?

And i'm surprized that after upgrading to the 044 you are still having fuel troubles what is your next step to fix the fuel supply ?

The cams your running are 272hks Yes? what lift ,as i heard danny just snapped a high lift cam and it is not that uncommon that they do (bit of a worry)

And the million dollar question what is your target boost preesure once everything is running right?

[Blitz]

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

[R32-GTS]

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.
