I have recently got myself a 2004 UK STI which has had a ECUTek re-map (carried out by Chris Davies of Race Solutions), RCM Air Induction, Upgraded fuel pump, upgraded top mount intercooler, APS exhaust with sports CAT, all done by previous owner.

What would be classed as a safe boost level running these mods?? The cars last rolling road session produced 342bhp.

Just wanting to make sure it's not pushing things a bit too far and would like some opinions

Thanks

 

I'm running 305 Brake @ 1.25 Boost.

my old 2003 STI (B Rawle mapped) was 1.4 bar (peaking 1.55) and that was circa 320bhp

The modified i/c would produce better results without silly boost wouldn't it?

 

I think from memory the previous owner said max boost was set to 1.5bar so guess thats not out the question?

 

1.4 bar is OK.

1.5 not sure.


I put boost, I meant 1.25 bar on mine.

Mine boosts to 1.7 bar thats standard turbo.

When I got the car it had been flashed mapped with a WR1 map by previous owner and ran at 1.6-1.7 bar boost for around 18 months.

I've had the car 10 months and after month 3 Mocom mapped it, checked it all and it's fine. Turbo takes it, no idea what to say really it's been running that boost for well over 2 years without issue and done 30,000 in that time and I have lead foot!

I have defi gauges reading this but I also had a mechanical gauge or something that Mocom connected up to make sure it was reading right which it was.

 

I think I remember Bob saying anything over 1.6 bar was pushing the envelope of safety.
