To make any SIGNIFICANT impact on this car's performance you either need to supercharge it, turbocharge it, or shed about 500 + lbs . Not a lot of ways you're going to attain that last option without destroying what this car is..

This past weekend I drove a Ferrari Pista. 700 + hp , 570 ft/lbs torque and the damn thing weighs less than 2,900 Lbs. Holy crap ! You step on it at pretty much any RPM level and you feel as you have just been catapulted ; it also sustains that acceleration until you let off. Got back in the GT and felt as if I was driving a snail. Almost made me think about having a Novitech SC installed, but it won't pass smog in California, so I'll just have to be content with the performance as it is, although no real complaints, it's perfectly quick enough for the grand touring vehicle that it is.

Aside from smog, I wonder how much additional maintenance you have to do before the engine tanks..

Good point. I know turbos ( aftermarket ) will shorten the life of the engine quite a bit, but low-moderate boost centrifugal superchargers not so much, although they still takes a toll, more so than a NA engine. Not sure how much boost Novitec generates.

Not only do you increase hp and torque by about 20, but throttle response is massively improved from stock. The car just flies from a standing start, and although I haven't done any official tests on it, I wouldn't be surprised if 0-60 was improved by at least 1/2 sec. That being said, this is still no sports car and guys shouldn't have any delusions about it either. The GT is just too massive and heavy to be anything other than a luxurious sporty cruiser, no matter what mods are on it.

If you're looking for the best all-around car that combines the comfort, good looks, and sound of the GT along with the athletic prowess of a world-class sports car, the Ferrari Portofino is IT! If I had to sell all my cars and keep only 1, it would be the Portofino. It's that good. Not only can you daily drive it but you also have 90% of the performance envelope of a 488. This car is a grand slam for Ferrari.

Thanks for the info and 1/2 second is a massive increase for what you mentioned. Next year i'm turning 50 (SMH) and was willing to drop $250k on something and was initially considering a Portofino and dumping the Masi. However, i'm having second thoughts on dumping it, cause a naturally aspirated F136 is special and a thing of the past, plus all the sex appeal I mentioned in original post. I have friends in the Ferrari world and they still say the Porto is "shunned upon", because it's a gloried Cali T and front engine. So I'm thinking to wait to buy the new Tri 8 that's replacing the 488.

Is it a "seat of pants" feeling?!

It's fine for a hi-revving, light sports car like the 430 however. This along with the antiquated 6-sp ZF auto makes throttle response way too lethargic. The Sport cats makes the engine breath a whole lot better and combined with the DBW, you get much improved throttle response. With these mods, my MC just flies from a standing start, even in Normal mode. I swear getting to 60 is quicker than before. As I mentioned previously, I would love to get it to the track one of these days to do some official runs to confirm.

Outside of these mods, probably the best improvement would come from turbocharging. Adding some extra 100-200 ft/lbs would do wonders for this car. That's why I could still never understand why Maserati would take their current best engine (the 590hp 3.8L TTV8) and give it to the Levante Trofeo instead of the GT. It's sacrilegious to think that a SUV would wind up as the halo car for Maserati.

How nice would this badass engine look in a GT?
So agree Trofeo wise and hasn't the GT been discontinued?!

Understood, I was definitely over zealous in my initial request! Driving an M5 everyday, that sucks the eyeballs to the back of your head in launch mode, jades you!

My '18 M5 is a cow too, but w/ 600/580 and awd, it's a demon!

Not looking to drag at all and I love it's GT nature. Just want more power at this point. I think the MC is as light as it can be, so I'll just add the suggestions from here and see where it takes me!

I don't want to ruin it's natural aspiration, it's part of the Masi's appeal to me. I have same good problem as you, cause my DD is am '18 M5, which is unreal....

Due to where my project is, my 4.2 can probably beat a 4.7 to 60 because of all the bits im missing (interior, back seats headliner and whole front end and hood are removed) probably adds up to 400-500 lbs
