I have a L92 that I'm looking to supercharge, I'm only looking to make around 550hp currently. I've seen a few post about boosting LS3/L92s and they all seem to run the stock bottom end. From my 0 experience on boosting, a 10.5:1 compression ratio is pretty high for a engine with no forged parts in it?

 

It's not really that high of compression to be honest, people have been doing superchargers and turbo chargers on stock engines for decades now.

The stock bottom end can handle well over 800hp without much of a worry with proper fueling and tuning. You can slap a supercharger on that 6.2 and not really care, have the correct supporting mods for fueling and with a good tune it will last a long long time.

 

10.5:1 kuulostaa korkealta paperilla, mutta GM L92 engine / LS-alumiinimoottorit kestää yllättävän hyvin pienen ahtamisen, kun setuppi on järkevä. Syy miksi ihmiset ajaa vakioalakerralla ~550 hp tasolla on juuri se, että rakenne on tehtaalta melko vahva, kunhan detonaatio pidetään kurissa. Se mikä tappaa nämä ei ole niinkään puristussuhde vaan huono säätö, liian kuuma imuilma tai https://casinia.live/ liian vähän polttoainetta. Maltillisella ahtopaineella, hyvällä intercoolerilla ja kunnollisella softalla tuo tehotaso on aika “sweet spot” stock bottom endille. Jos haluat mielenrauhaa, niin silloin kannattaa keskittyä säätöön ja lämpöjen hallintaan ennemmin kuin heti alakerran rakentamiseen.
