Can anyone tell me what boost presure an STI 7 runs with PPP or without in BAR or PSI.

Peak Boost and Held Boost.

Thanks.

Arron.

 

With 3 inch MRT exhaust + high flow cat and SS up-pipe was running:
1st, 2nd, 3rd - 0.7 - 0.9 bar
4th - 1 bar held ( peak was 1.4 )
5th - 1 bar ( ditto )
6th - 1.05 ( peaking in vy cold air to 1.5 ) have added dawes since the weather has warmed up.

With dawes I run it at 1.2bar with no peaks or creeping.

 

Question for Swaussie. I keep on hearing about this Dawes device. Can you tell me more about it; is it worth it; how dificult to install; price and where can I get it from? Also I can't seem to get my hands on any NF Race octane booster. Do you know of a distributor over here in Switzerland? I've got an STi7 tuned by Digit Power and eventhough it's running like a charm, thought some octane booster might add extra security on high speed runs on the German Autobahn.

Cheers

 

Sorry to hijack the thread Arron.
Bigdude, I would highly recommend the dawes. It was very simple to install and tune to the boost I wanted. It also stopped the spiking which was making me nervous during winter. I got mine from JW Racing in the UK. Boost seems comes on quicker (getting 1.2 bar at about 3200 rpm) and it holds boost instead of the dramatic taper off over 6000 as standard. Made the car even more fun to drive.
I have no idea of where to get octane booster in Switzerland and have looked everywhere for it myself. The Shell Garages in Germany sell optimax now which makes a noticable improvement when driving on the Autobahns. Give me a mail if you want to know more Bigdude.

Back to you Aaron
