317Rwkw - Stock Injectors - Now at 360rwkw

[Tobey]

OK after a slight misunderstanding of what I was told:

Race - Magenta - 361 @ avg 16psi - This goes from about 18psi down to ~14psi - was 365+ but the tune (timing I think he said) had to be backed off due to slipping clutch (see graph)

Street - Dont believe the actual run is on the sheet I have - will have to chase this up tomorrow.

Low Power - Green - 345 @ 10psi - note the torque line when I say low power.

My car was left in the hands of the tuner and he made it work for him - he explained to me he doesnt work on static boost figures or any target in mind, he does what the car likes and that's the result. He knows the cars back to front and runs what he thinks is safe. According to Jim the car did it easily, with never a sign of strain on the motor and its well within its limits.

The street tune vs the race tune has more mechanical protection built in (timing etc).

The 10psi tune has very little timing on it I beleive and makes very little torque, however still has a high peak power figure late in the rev range.

To be honest, power figures dont phase me that much, its more about the MPH at the end of the strip, depending on weather, I'll be runing it on wednesday night.

Also the turbo is stock, hence why the boost tapers off...

Looks good. I wouldn't have thought that 6psi less only would've netted a minor loss but obviously the tuner knows what he's doing

Good job, enjoy it.

I think it only comes down to about 3psi at peak power, as 10 will hold steady, yet without a new actuator it wont hold the 18psi it creates the peak torque with earlier in the rev range.

So at 361rwkw there is 3psi difference compared to the 10psi at 345rwkw.

Yet looking at the torque of the low power tune it is very evident that its only at 10psi as it has less torque than the generic tune shown there.

time to go external gate I say nice work.

Clutch is slipping now... Cool night in fourth gear, slliiippppp....

Going to go with a CI twin plate, with a higher clamp load pressure plate - 1500kg IIRC. Recommended by tunehouse, apparently good for over 400kw, also cheaper than the MW alternatives.

I'd tend to take it easy on this motor mate... by the sounds of what you've said , its been running on the edge (14:1 on boost) for awhile now, with high inlet temps and super lean AFRs its prob been pinging alot too... could be a grenade waiting to pop.

Not saying the tunes in it now are bad, I'm sure they are awesome... I'd just be keeping the boost down.

As I've said before, I trust the tuner, so I'll go with what he has given me.

Also no pinging in the time I've owned it - which wasnt taken easy, nor when it was leant on, on the dyno. So no reason for it to happen before I owned it.

Go hard man, mine loved 360rwkw on the sh*tty bottom end. Raped it at powercruise and nearly every day of its life. Only let go last week cause the timing chain jumped 6 teeth.....

I have no intention of babying it! Otherwise I would have bought an NA...

What clutch did you run in yours?

[Anchor]

NPC single plate 5 puck. Ceramic. One of the ones that's a bitch to drive until you get used to it. Came with a billet concentric slave as well. Was awesome. Sit on 80, hit a long sweeping corner, clutch it in 3rd off limiter and it gripped straight up and spat the ass out. Never slipped for me even with MT's on. Old mate was launching it at 4500rpm and it just bit down.

Not even expensive either, bout $800 I think all up? + fitting and machining of flywheel.
