Slowest R5 in the world- thats mine.
« on: 12:57, Thu 06 August 2009 »
What gives here ?   Was looking forward to driving this little Mother for the first time however was shocked to get such poor performance from it.
Similar to a tractor i'd say.... :shock:
This car has....re-jetted carb [how can one tell if thats not bulls*** ?]
                    4" straight thru pipe
                     Double capacity alloy intercooler.
                      T2-T25 Hybrid turbo
It couldnt pull the skin off my Mothers custard so i checked the boost level and she was only running at 5 PSI.....why would that be ?   Why would anybody REDUCE the boost to that level.
Any ideas chasps?
Maybe it was done for a reason or to hide something ?
I'm all ears !!!

check for boost pipe leaks first. if all is good wind the actuator arm in making it shorter a few turns and see if you create a little more boost. then go from there.

Double check for boost leaks.

Does the turbo sound like it's doing anything? If it has a leak and is set to lets say 15psi it will whizz it's tits off trying to compensate for the leak, resulting in a knackered turbo.

Thats only if it has a leak of course. If it hasn't maybe it was set low and had some sort of in-car boost controller before?

Thanx for all the tips Guys,
Yep, the first thing i did was check for leaks but nothing.
Turbo is working fine.
The only reason i can see that it is on a lowly 5 psi boost is that there is a in car boost controller however it has not been connected up.....so maybe somebody has played with the actuator and forgot to reset it back.

Having the items i listed above i should be safe in cranking it up to say 14 psi dont you think?
 How does one know if it has an uprated head gasket is the big mystery. Mmmmmm.

Usually when fitting a uprated head gasket most people opt for the hi-tensile headbolts aswell.

Hi-tensile head bolts are the hex (allen key) type capscrews while the normal head bolts are just well normal bolts.

A peek through the oil filler cap and you can see.
