Static Comp For A Rb25/30

[MRHD66]

Hi guys and girls just wondering what a good static comp ratio would be for a RB25/30 turbo runnin 15-25 psi cheers

On pump 98 stay between 8.5 and 9.0:1

[MRHD66]

I was thinking 9.0:1 for more response off boost

would 9.2 be high for e85 ?

rb26/30

[N1GTR]

Not really, no

[TiTAN]

mines 9.3:1 on 98, if its dedicated e85 10:1 or more is easily possible.

MRHD66,

What turbo are you planning on running?

hopefully a GTX3580 with a 1.06

[MRHD66]

Meant GTX3582

Get a HTA GT3586 from forced performance. Results look like the HTA stuff is better than the GTX. Better behaved in terms of spool and power, the GTX will want more boost to do its thing whereas the HTA shines most with lots of boost but still outperforms its predecessor for the same PR.

There is some valuable info in the 'budget 370kw RB26' thread in the general FI section.

From my experiences with SR's 9.5:1 seems to be the upper limit of FI high comp when wanting to extract the most and stay on 98. I would stick to a CR around the 9:1 mark if possible.
