hy guys its maybe a unusual question but how can i put back my engine horse power to 132 original PS BHP

i have piper cam 285 stage 2 turbo mongoose exhaust

i need to push the power down to passe the MOT
(i live in a other country..)


thanks

 

surely you mean engine emission for mot?

 

yes because i need to have 132 bhp to pass the mot how can i put the power back to 132 bhp like origine

 

ahh,
trying to get dead on back to 132 would require putting it all back to standard or a how about adjusting the actuator to give less boost?
im sure someone will have a idea

 

Hold the waste gate open, restrict the intake etc. My car with a stage 2 turbo, exhaust etc made 115bhp with 5psi before rebuild. I assume less than 132bhp is OK?

 

hi unless your mot stations have rolling roads with dyno cant see how they test your horse power !! more likely its emissions and noise pollution as your mot is very much like ours !! down load decabel app for smartphone or tablet ( they usally free) find out what level @ what revs u need to pass then if u have to change your exhuast for test change it swap it back later ( over here kit cars cant be over 100db @ 3000 rpm as seen on wheeler dealers ac cobra episode) after whatching that episode took db meter app outside started up my s2 84db @ idle didnt bother finding out what it @ 3000rpm as for emissons stick super unleaded in and cross your fingers or get it tuned up!!

 

What country are u in ?
Like said it has to be emmisions and not power

 

Just turn your mixture screw anti clock wise till it passes and make sure it goes back exactly were it was before

 

I would imagine he's in Luxembourg....

And other country's have incredibly strict MOT like tests. I don't think you are technically aloud to modify cars in some EU country's, so perhaps a dyno test on a suspect modified car is needed for it to be road legal.

Rob,

 

exactly rob its this the problem well i need to be near the origonal 132 bhp

the xr3i have 105 bhp
the rs turbo with 0.5 bar (original) turbo have 132bhp

well i with my piper cam an mongoose exhaust and stage 2 turbo

what do you mine hold the waste gate open and restrict the intake ...? there is the nut on the waste gate ? need i to turn the nut wich side i have to be nearly to the 132bhp 122 bhp will be ok ....

wont be long before we get mot standardised across europe then we all fucked! if you go efi cant you remap for the test !!

 

up rob ?

 

does it not hurt the engine to run it with the wastegate open?

will a realy loose some bhp if i run the car with the wastgate still open ?

or i will runn it like rob did it after the engine rebuild like 5 psi to have 115bp or maybe 6 psi to be mor near the 132 bhp

 

Wastegate open and pressure down can be done both with the same component. I think pressure down is much better then op WG all time. Take ur WG off. Mark good where it is now (length) and then make it longer. Till you almost can fit it without pulling (just a lil bit). Then your pressure will be around peak of 0.5 backing to 0.4 or sg. You have some upgrades that you don't require the 0.7 peak to 0.5 of the std

 

ok thanks i will do this

 

Sorry I didn't reply. Red Bull is correct. You could also adjust your throttle cable so you only get 1/2 throttle

 

WELL GUYS i did the DYNO test today at the result is 153.8 bhp at 5599rpm 221NM
at 30 degrre outside temperature (very hot)

i really put the acutator on my t3 stage 2 longer that i can fix it witout poulling on the wastegate

i only have 0.3 bar pressure

but i have the piper cam airtec intercooler mongoose exhaust ....hmmm i will try the MOT again like this

 

Loosen the throttle cable so you can only get 3/4 full throttle

 

0.3 bar will be enough i think. What pressure where you running on the old set up?

 

What was the boost at 153.4bhp? I think you will be fine at 0.3bar too.

Bit of a odd thread, its the opposite of what most people ask

 

Reversed engineering!

 

i had this power at 0.3 bar

before the position off the nut was 1.2cm on the wastgate

it was setup like this when i received the brand new stage 2 turbo t3
didnt know how much pressure i had

 

When will you go for a new try?

 

i need to drive some more KM

i only had 80km after the engine rebuild and than put it on the dyno was not the best thing to do but i didn t had the choice

 

i passed the MOT is ok no an other problem on a new treath
