Just fitted a boost sensor for the SECS unit on the car to get the true boost reading. Car is

MY01 WRX


PPP ECU
Miltek Sports cat exhaust
Up pipe de-cat
Green panel air filter
STi7 intercooler

The boost reading I am getting is 1.37 bar (20.1 psi). This seems really high!!!1 Car has been in this set up for ages and drives ok. Should I be concerned!!!

I get 1.37 on mine mate but thats all mapped for with my tek3

sti7 intercooler ... cool
could it be a bit of overboost with the downpipe?

I ve still got your wheel clearner and Jumper... its about time we had a meet

Fizz_daz

it tails off at about 5 and goes down to about 1.1 by the rev limit I think (15psi)

yes wee need to meet up... I'm freeish this weekend and was planning to come to Worcester to see Rik at some point...

Squizz

Oh you were, were you...

Ya big boost freak, you!

Ha, I can talk - Our wee ikkle T25 puffing its heart out at 15psi

We ought to organise a meet very soon. We haven't all got together since... "Steady" Waynes leaving do?

Noticed today with the cooler temp that I'm getting 19.5 psi (1.32 bar) in 4th & 5th on a std PPP WRX.
Up til then, 4th was getting to 18.5 psi.
also 2nd & 3rd were up to 18.5 psi, from their normal 17.6 psi.
I thought at these boosts fuel cut would come into play, unless its been raised considerably higher than the std WRX).

Well I suppose I am feeling a little better perhaps the combo of all the extra little bits help (was on normal super as well though so might get higher ) anyhow I have got a knocklink coming soon so that should ease my mind more or panic me!!

Fizz_daz

So is it safe and correct then?

I'm running a MY01 With PPP and full scoobysport decat, I get the following boost readings from my defi's (quoted bar but defi's read something else which is almost identical to bar).

2nd - 1.2 to 1.3 bar
3rd - 1.2 to 1.3
4th 1.3 but will often peak at 1.4
5th 1.3 but will often peak at 1.4

all trail off at about 5.5k revs I think.

Can't remember 1st, I'll record a reading through the gears over the weekend and post it up if you want.

Cheers

Chris

Hi,
i've got a My01 PPP 39k on the clock (got 252bhp on the rollers at G-force) which looking at the figures chris gave mines about the same using a GReddy electronic boost gauge, 1st gear peaks about 1.0 - 1.1bar, hope this helps
2nd - 1.2 to 1.3 bar
3rd - 1.3 depends on the load
4th 1.3 to sometimes 1.4
5th 1.3 to sometimes 1.4

Oops,
I thought my figures were too good to be true.
I fired up delta dash today to compare but couldn't get above 17.6 psi.
The boost gauge (SPA), once powered up, is reading 1 psi without the engine on so my readings are b*ll*cks.
