Horsepower Limit With Stock Engine

[polverari]

Hello!
First of all, I'm Brazilian and sorry for eventual mistakes and bad english. (I'm not using a translator ;-( )

I have two doubts:

1 - With stock crankshaft, stock rods and stock pistons, what is a safe horsepower limit (In crank)?

Example: Stock rods, stock pistons, stock crankshaft, but upgrades like intercooler, turbo, injectors, e85, walbro 255, ECMLink, etc.

2- With wiseco forged pistons , stock rods and stock crankshaft (4g64), what is a safe horsepower limit? This is my actual setup. I have wiseco pistons for stroker (forged), stock 4g63 rods (150mm) and a 4g64 crankshaft. So, i'm running a 2.3 Stroker.
I have a FP68HTA, Walbro 255, E85, 1200cc Precision Injectors, OEM head 4g63 (100% ok), Wideband AEM, VRSF Intercooler, 3'' exhaust, 2.5'' inox pressurization, K&N filter, original MAF, TIAL BOV, OEM exhaust manifold, 1200lbs clutch, acl bearings, OEM gearbox and.. I guess its all

ATM im running with 1.1 bar (16 psi) and 360hp (CRANK)

I'm using the car all days, as daily car. Is my only car. I drive like a old woman, but sometimes, obsviouly, i like to go hard. So i want go about 400-450 in crank but i'm afraid. Its safe?

Thank you.

With stock 7 bolt rods in a stroker you’ll probably fold one up around 400whp.


The weakest link in the stock bottom end is the rods.
