How much boost? Did you dyno the car?
Sadly not yet, with logs it should be 290 to 300hp.
@@TomoReso do you know maybe how much boost ia it making? Stock ecu or standalone?
@@maticomahen7498 depending on rpm, 0.3 to 0.5 bar, 970 kg/hr maf reading, nearly at the limit in 1024 mode, stock ecu handles great this engine with sc and lower boost.
@@TomoReso what size pulleys do you have? You should be getting more boost with this charger
@@maticomahen7498 210 crankshaft pulley, 93.5 standard eaton pulley, 2.24 ratio giving 15680 supercharger rpm at 7000 engine rpm. Boost is not as calculated, 0.5 bar, well not always at every rpm, but the calculation for stock maf limit is nearly dead on precise using maf logs. The air drawn into the engine is as it should be, it all depends how well your engine is breathing, ive also ported the supercharger and engine head, so i believe it all flows good.
