560cc EVo 8 injector max horse power on b18c1 engine.

 

Assuming 80% duty cycle:

280 HP for a turbo car on gas
310 HP for a supercharged car on gas
340 HP for a NA car on gas
220 HP for a turbo car on E85
240 HP for a supercharged car on E85
260 HP for a NA car on E85

In the real world they can do 375whp on a dynojet with a single 255 on an Evo before they max out. This is at a 12.0 which the above doesnt take into account.

 

Id say 350hp.

 

I agree somewhere around 350-375hp, but of course depending on fuel pressures, type of dyno and type fuel. I would recommend just invest on a good set of 650cc injectors to give you some more head room with out the worries of maxing out the injectors duty cycle.

 

I personally own an evo and we can't get over 290awhp on a low reading mustang dyno with those stock injectors.

Just wondering, whats the going rate for the EVO injectors? I have more than one set that I should just sell.

 

$70-90ish...

that's just because dsm 450cc are $40-50, and used pte 700-900-100cc injectors often sell for $150-200 if that.
