Hi I think I have lost some power from my MY95 WRX. It is fitted with a full HKS de-cat system, HKS blow off valve, K&N induction kit, Blitz iridium spark plugs. Would a warped and/or cracked flywheel drain power? Also would a worn clutch Drain power? Does anyone think that getting my scoobyecu fitted help with this power loss. I always run it on Optimax but not octane booster.
Please help as I would of thought that with these mods I should be seeing a good power increase!

 

Anyone?

 

I wouldnt run with those mods on Optimax alone without some sort of remap!

All the mods you have revolve around getting more air in and expelling it quicker. You can just about get away with Opti alone on a standard WRX but I should be surprised if its not seeing any det TBH.

Worn clutch will show up by the revs rising and you not going anywhere ie, its slipping.

Have you got a boost gauge? Has it lost all power or just on boost? Bit more info needed.

I haven't got any det as I have got a knocklink installed and I don't get any lights other than on start up.
I do have a boost gauge and I do hit around 0.9bar but it just doesn't seem to pull as well as it used to. I do still have power it just seems slow when on boost compared to my mates standard version.

Would having 18s on make a big difference?

 

having bigger wheels wont make much diffrence.your car is probably hitting the boost limit. ie getting fuel cut. the boost limit is set to 15psi.i would get a fuel cat fitted so you can run on normal fuel and fit a hks fuel cut defencer.

 

Fuel cut is quite voilent so its not that.

I think that I am gonna have to get the scoobyecu fitted and see what difference that makes with a veiw to getting a full re-map in the future cheers for your help guys.
