High Explosive

hi thinking of adding to my mods putting fmic on and remap upto around 300 hp will the standard 380`s hold it or do they need upgrade,thanks

The 380's will be at the very top of what they can do for 280-300bhp. Next step is 440's, probably a better bet but you'd need everything set up.

well not sure whats needed but i have full hks exhust with sports cat group n down pipe td05 with matching ecu hks mushroom filter and looking at 440cc FMIC and live esl daughter board and live map will this be enough.

Ideally with the 440s and the rest is fine however i wouldn’t bother with the fmic at that level.

will it still pull fine and not bottom out with the standard Inter cooler but if this is correct i`ll be happy as it look a pain in the bum.

If it's a classic on the slanty small intercooler then I would advise an upgrade to a larger cooler if you want 300BHP+. It doesn't have to be a front mount but either an aftermarket top mount (suitable for Pre96) or do the required work to get a 97-99 TMIC on there.

380's are at there limit just over 1.1bar.
So you would either need a pump and reg to up the pressure or change to 440's
To reliably get 300BHP+ you would need to be running 1.25bar+

I had 320/300 on a UK97 turbo but ran FPR in situ along with Apexi pcf mapped by Andy F. Top Mount and 380's were fine. (TD05 turbo btw)

i am just curious how you guys get so high figure on your wrx or sti? i am only getting 240hp at the wheels on sti v3 with the usual intake exhaust/FMI and APexi FC. i can confirm that the standard wrx only gets 150hp at the wheels and an sti around 180hp.

The above are flywheel figures while yours are at the wheel.

In my experience, with a Walbro pump, the 380 cc on a Classic will max out around 280bhp or just over. Several people have 380s running just over 300 bhp but I don't know how much the fuel pressure id bumped.

Again, referring to Classics, even 5s and 6s, charge temps rocket up beyond 300 bhp with any prolonged WOT so my findings are in line with Scott's.

yeah my 310 was 240 at the wheels.
