currently running 550cc injectors on car, looking to run car on 20%ish meth, obviously booking car in for re-map but want to know if injectors will need uprating/flowmatch, 400+bhp at mo.

you'll be running a pretty high duty on them i'd think currently so i'd imagine they need uprating/flowing, is it on a 2.0litre? you running a fpr to bring up the pressure?

seem to recall 98% duty cycle being mentioned, but not completely sure, i do run fpr yes, cant remember wether its set at 3 or 4 bar, bloody useless i know lol

Running 98% is huge strain on them, you need extra flow to cope with the meth. 800cc injectors would be needed

is it suitable to send them to lateral, would support about 1000cc then, or should i be looking to buy new?

Can be worth while selling them. I managed to sell my STI pinks for £125 and got my 800's for £170 IIRC where i think it was about £100 to have them flowed.

Graham (enginemapper) recently mapped a car which I built the engine for, He's running 850's and with 20% meth they were getting close to max at 400bhp, this is due to having to flow extra fuel to compensate for the meth.

Is he running a FPR on that too? My 800's are from MattyB's car that was as almost 500 without meth on with these in.

thanks for that wms......so would it worthwhile having injectors flowed to 1000cc odd at lateral then?

cheers birchy....was thinking about buying some 440cc and getting them matched and either keeping or selling on my 550cc

If you have WRX injectors(380cc),they can be flowed to 700-740cc,if you don't have they're cheap and don't cost more than £40-£50
