A suggestion for the 5.0 hood and air intakes.
Move the hood scoop openings to the outside on the hood where the airboxes are located and work on an air intake system.
Interesting. all the turbo and superchrger
mods are great, we would love to work on one for Genesis. personally I prefer turbos for their efficiency. they also don't put unnesessary load on the engine's internals, where as supercharger is driven buy the engine and about 20% power created goes into driving the SC.
We did a twin turbo kit for 94-96 Impala SS (see thumbnail) and it was lots of fun.
We did not build the engine up, SBC will handle 500 HP safely without any
mods. And - MAF system handeled extra air flow nicely, never threw a code.
If driven easy you would never know there car has a turbo. We did put an Aeromotive fuel regulator with pressure reference port and bumped pressure to 52psi. Down low PCM shortened injector cycle to have 1:14 AFR and when
we stepped on it it would go to 1:12.5 AFR. So the PCM was always happy and we never leaned out. If someone were to have same type approach to Genesis
it might have useful application. The turbos have to be selected carefully though - with A/R fairly low, about .65. and limit wastegastes to about 8.5Psi
Turbos like that , with fairly small inducer sise - maybe 58-60mm would spool
up quickly, have a go at low - mid range and somewhat calm down after 5000 RPM. The car would be a monster to drive, have big power in the mid range and some extra on top, but not too much to overload engine at high RPM.
As for our efforts, we are bound by the rule of not compromizing warranty, as our package(s) will be offered as dealer option for new car sales.
I'm sure someone will step up like the outfit from SEMA, and develope workable package. I don't know what
aftermarket hardware is awailable for 5.0 or 3.8 - like pistons, cams and so forth. Also - who can beef up tranny and rear end?
So, for now we'll work on Cold air intake. I'm leaning towrds leaving stock boxes intact, since they are already taking air fron the front,
and adding two cone filters drawing from under the scoop. We'll have to buld a pan to keep hot engine bay air isolated from the new flters.
in other words, have a cold air intake not instead of but in addition to stock one. Commonly we can expect 10 extra HP on top from a mod like that.
With free flowing mufflers we can hope to get 440 HP ..
