Running HB2T5, after 5k the N75 duty starts to drop and the boost drops away. Should a K04 not be reequesting more?

[Simon L]

Is it as simple as turning the boost up with the SPS3?

At 6k the N75 duty is only 54%, so its venting half the boost!

 

[m0rk]

had you started to ease back at 6k?

The 5680 figures look respectable, good airflow etc

inlet temps had risen too - so it's possible it started to pull back slightly

 

[Simon L]

These were taking whilst on a RR, the operator was driving. Dont think he lifted off til after 6300rpm.

Made 230bhp and 270lb.ft.

Will changing to HB5 bring in the boost higher up?

 

[m0rk]

there's no chance 230bhp is 197g/s though.

 

[Simon L]

I'm assuming you reckon 197g/s should be producing more?

 

[Martyn]

Correct!

 

[PhilW]

Unless the CF's are off the scale, but i'd expect to see that down low tho.

As i said on the other thread HB2 T5 are really soft settings.

 

[Simon L]

Will knock them up a bit and do some logging, see how it goes. Cheers lads.

 

[Simon L]

Done some logging tonight and the N75 duty is now at 80% over 6k with HB5, instead of <60% when on HB2. Holding 16.5psi @ 6.5k.

CF's are max of 3, and the timing is on 5.

Logged speed too, 0-60: 6, 0-100: 13.4

 

[Simon L]

Temps were drastically down too, peaked at 40'C tonight, compared to 60'C at the weekend.

 

[PhilW]

Try HB6 and T6 to see what your logs look like.

Post them up. We like logs on SCN.

 

[Big_daddy]

It be alot cooler at night and getter a lower reading as during the day

 

[DPJ]

Try HB6 and T6 to see what your logs look like.

A reasonable starting point IMO.

[Simon L]

The 2 logs above are on HB5T5. Will do HB6T6 tomorrow.

 

[PhilW]

Theyre are lookin about right to me tho, worth trying hb6 t6 tho to see what it looks/feels like.

 

[Simon L]

After searching for some LCR logs, holding 14psi to 7k seems to be the benchmark. I never took it that far tonight, but don't think it will be far off that.
