i have 1998 sti type r and have never had it on the dyno, would i be right in assuming it to be 300-320bhp with the mods on my car?

mapped apexi power fc
Walbro 255 fuel pump
full de-cat blitz nur spec exhaust
apexi induction kit

 

320 could be about right, it depends on what settings the apexi has been mapped to, and who mapped it

 

agree with above

 

I thought so too.. I was qouted 375bhp by the last owner but i am sure you cant get more than 350 on standard 440 injectors.. It also doesnt feel like 375bhp, my previous car was an 380 bhp evo 6 RS and the type r Feels nowhere near as fast as that..

 

also has in ihi turbo..
