And here we are, received the finished photos from Simon:
( albeit minus strut
brace fitted
)
So I organised between Simon at YVS and Will at Race Dyno Tuning the best
day to meet and organise the mapping.
Which turned out to be Monday the
30th of September.
problem being is that Will needed to start at 9am, and RDT is 30 minutes south
of Doncaster.
Me living on the Ashdown forrest in the south meant that its a
near 4 hour trip involving a 5am start, two trains, a tube and a taxi and even
then I wouldn't get there till 9:40am.
And because of this Simon very
thankfully drove the car down followed by Liz
( his wife
) to RDT about an hour
south of YVS.
So myself and my stepson who had traveled up with me for the day finally got
there just as they were finishing plugging in the mapping gear.
Hours of mapping later we were starting to build up the power, after sorting
a base map and altering idle and other things etc.
It started getting interesting.

We started building up boost, but then hit a snag.
And potentially a very bad
one.
The fuel pressure reg gauge was showing heavy pulsing that could be felt
on the top of the FPR.

We tried to figure out what could be causing this.
One
thought was that maybe the fuel gauge in the car was incorrectly reading,
which has never happened before
but it's worth a try.
So Liz very kindly
drove a very very stressed Jordan to the closest Shell garage to fill up a 20ltr
can with V Power.
The nightmare of potentially having to have the car shipped back to YVS to
inspect an issue in the fuel tank and then pay another
£150 worth of tickets
back home on the train was not doing by mental state well.
However I arrived back to Simon telling me he thought he had cracked it,
and he had.
It turned out to be the OEM resistor for the fuel pressure wire had
been damaged during the heavy boost loading sessions, where Will loads up
the dyno to replicate heavy load but then applies heavy boost.
Doesn't sound
good and Simons not a big fan of it due to the excessive heat it produces but
each mappers different on how they get their results.
And Will gets good
results.
Anyway heart attack averted we cracked on with the mapping, now being
close to 6pm and the nights drawing in and an entire UK storm about to hit
we came to an end
( we thought
)
Final power figure attained.
363whp
/ 425bhp*
@ 1.4 bar of boost
* approx based on a half way between 15% and 20% transmission loss.
This was with only 21 degrees centigrade of intake temps which is incredibly
cool, and seeing as heat was always going to be out biggest limiting factor.
shows very good scope for more power.
The goal was always to make a great road car, road useable power not some
dyno queen.
Progressive power with a smooth delivery but a fun shove at the
end.
Will has definitely done that
! We were at 7pm now and had been mapping
since 10am
! As said there is scope for more power easily, but with the OEM
map sensor only running to 1.5 bar of boost 1.4 was the top.
So all thats
needed if I decide to, is buy an aftermarket larger map sensor and up the boost
and map.
All was not done though.
.
.
Simon advised me to take the car up the road, by
now in the hammering rain and dark to make sure it drove ok, it hit boost cut.
So I drove back to RDT and Will cam out to confirm and we took it back
rose the boost cut level to 1.7 as it was set at 1.5.
This fixed the issue, and me and Ollie were on our way home.
Near on 4 hours
of the worst conditions I've ever driven in, with AD08r's
yeah it was
stressful.
But we got home.
Ive had two days to drive it in good weather since, and it does not disappoint.
the noises it makes are insane, the G25 is like a jet engine behind your ear.
making all manor of turbo sounds.
And most importantly it drives great, with added madness
Next up, painting lots of parts to make the bay look like its had the money I've
spent
!
