Took my RS to Dastek in Fife today for a setup and to fix some niggles. Have to say very professional and credit to Russel who knows his stuff.

Unfortunately the dyno highlighted that my actuator was possibly weak as it was only making 0.3 bar of boost (about 5 psi) hence only getting 160bhp at flywheel. Probably due to me fitting it but have my old one to try out.

Looks like I can remove the starter to swap it over, is that correct?

Anyways hopefully that will fix the problem some more boost and should be able to achieve 200 bhp.

Dont need to remove anything to change the actuator mate.

Whats your spec mate?

kermitt

Standard rebuild bottom end and head,
Airtec FMIC,
Magnex exhaust,
K&N induction kit
Chipped ECU,
Stage 1 T3
Running MFI

Still to fit Koni adjustables and a OMP front strut brace. Hopefully getting a cage soon and maybe some new racing seats.

Had my saph on their rollers and was impressed with them.

Might be worth a look.car sounds like it running good dude!i had same problem with weak actuator,7psi was my max lol.still made 160 odd with pretty standard spec like yours.

kermitt

Yeah Russ said it was very good numbers considering there was sod all boost. So how do I remove the actuator then without removing starter motor etc?

chaffe

Good power for f*'k all boost mate. try tightening the actuator you have, slacken the 11mm lock nut and screw in (shorten the rod) by about 5mm, this will give you more boost and tighten the actuator up. If you pull of the boost controll pipe to the actuator does it still only make 5 psi?

The two 10mm nuts holding it to it's bracket, and the C clip on the waste gate arm.

as karlos mate said its an easy job then adjust it like chaffe said till you get the boost you want

stwibs

once you have set the boost you will need to take it back to get fuelling checked.

kermitt

Job done seems to pull stronger now. Disconnected the crappy boost gauge I had as it sounded like a leak coming through the dash.

Gonna pop out later for a quick run and check over hopefully track day tomorrow!

160bhp from 5psi?!? surely not.

chaffe

how much boost does it hold now then mate?

kermitt

At the flywheel yes, 100 or so @ the wheels.

Dunno what boost I don't think the cheapo gauge was working. Feels a bit more lively now and not as flat. Only turned it two turns on the actuator.

Karlos G

Yeah the dyno is way off there, a brand new RST 20 years ago only made 132bhp at 7psi

chaffe

i agree, must be nearly 110 bhp at that boost?

Karlos G

iTrader: (4)

Yeah none of those mods will give it any more power at 5psi.
Shows how far out Dyno's can be! lol

Well I have pretty much the same engine aside from the stg1 turbo, And mine makes 165bhp @15-16psi

Stage 1 is just 360 thrust bearing so no actual flow gains, his IC will help but not until running over 12-14psi, so just a standard RST really.
Your figure is pretty much what I would expect for that spec and boost.

ryan_gwa

How much was it at Dastek? Going to need a decent fuel set-up and run on the rollers when mine is done. Miles away yet, but nice to know.

Think i removed my rad and interwarmer which made it really easy.
