welcome to ownership. also, I see where you're going with your first two posts... and I like it. [emoji106]

 

Is the Novitec CARB certified ? I might be interested in adding that but unless it's CARB compliant and has a certification number it's useless in California ...an probably most other US Sates which have smog testing ... unless you want to de-install it and reinstall it every two years ...
Seems that the rest of world does not have this problem, so pretty good to at least have that option, if you want to SC your car ..

 

There's a lot if you just google search "novitec supercharger maserati"... Similar to AaronE I like your plan. I'm interested in supercharging too.

no pics of the actual engine though... just the top can looking thing instead of the intake "horns".

oh, and interesting, the Novi MC had their front bumper painted like mine! only black in the small strip above the splitter.

 

I'm starting to wonder if it truly existed haha I've searched high and low and I've never seen anything but a picture of the cover piece. I'd imagine this car is no harder to supercharge than anything else using a centrifugal supercharger, plus there is a ton of room in front of the engine for piping, water to air cooler, etc.

 

Talked to a Novitec dealer yesterday and was told they don't provide anything engine related for the 4.7L at this time anymore. No ECU tunes, no supercharger etc. May explain why it appears to be a "ghost?"

 

That sucks, I have a 2007 GT500 and went through a few set ups. I have a couple of superchargers lying around including a centrifugal I never used. The roots ones would probably not work.
I think the shop I have been using for years would be able to put a custom setup together, they build custom race cars, but not sure about the tuning, which is the key.
Might be a project for next winter. I'm assuming internals are not that strong ( cant find any info) probably not forged probably no sleeves so 5-7 lbs. of boost max is what I'm thinking. The key is getting it tuned after the install. might not work out.

 

Did anyone follow up on supercharging a GT?
It's certainly an interesting project, especially with the new brushless motors and LiPo packs available. They go up to 100C discharge, so a small pack could deliver a lot of current.

Ideas?

 

Bumping this...

I'm also looking at the feasibility of mounting a centrifugal SC. Here's all I could find searching the net, indeed, the Novitec people are rather good at keeping things under wraps.

On the teamspeed forum there are a couple pics of kit lying out prior to installation, the most valuable photo in my opinion was this one (below), giving some idea of the mounting position and orientation of the supercharger.
https://www.maseratilife.com/forums/attachment.php?attachmentid=120987&thumb=1

I was at first rather confused, using intake side/air filter side as reference the main body of the supercharger would have to remain medial (towards block) to that of the serpentine belt. It finally clicked when I viewed the accessory positions, and in particular the water pump of the 4.2 engine, compared to that of the 4.7. On the 4.2, the water pump is mounted lower and therefore offers a nice niche between the head and water pump on the passenger bank -- I believe this to to be the location of mounting for the Novitec system. Unfortunately we do not have this space on the 4.7, and I can only see the possibility of have the body of the SC facing out, filling the large area currently populated with the large air filter box, and beneath the strut tower brace/connector.

 

Thanks for the PIC, I am confident that my Gt500 shop can set up a custom kit ( supercharger or turbo modified mustang kit 7-10 Lbs of boost), I would rather do a supercharger. As for fuel with some injectors and a Boost a pump should be ok. The issue is the tuning, do you guys know of anyone who would be able to custom tune it? Is it the same coding as a Ferrari? The tune is the key. Everything else can be done in my opinon.

 

The Novice supercharger is just a kit put together by Novitec tuning. The ACTUAL supercharger is a Rotrex.

Rotrex A/S

and specifically:

they tell you which actual supercharger unit to use for the . The reason they refer to a distributor is the distributor supplies the brackets and tune... but you could arrange this through another workshop, probably cheaper. The tune can be done by anyone who offers ECU tuning for a Ferrari. I know plenty of places in the UK, am sure there's loads in the USA.

Novitec don't really deal with the older model cars anymore, so I'd just contact rotrex direct for their recommended unit, and get a local shop to make the brackets up (really not hard to do, same as any car).

All the above being said, I don't see why you can't just get a local shop to make up brackets to fit a vortech supercharger; should be cheaper.

 

Would be awesome to see someone install
SC in 4.7

 

Spoke with a local well respected shop today, they indicated proprietary programming equipment is necessary to tune Maserati's. So no doubt not an overly easy task to line up a shop to perform this. Most options appear to be cookie cutter mail order "chip" or flash tuning, and no piggy back systems for these.

All that said, I did find one shop which appears to be a viable option; if you're in the Midwest you're in luck! Maserati Tuning | Smokey's Dyno

Stock injectors appear to be easily sourced Bosch branded, and thus compatibility to other aftermarket injectors shouldn't be an obstacle.

Things are looking not too bad! I need to review engine specs a bit more. The compression is 11:1 (+- .2), which depending on the camshaft specs might limit potential boost a bit.

I need to sit down in order to digest these:

Intake valves: 9.5 mm +/- 0.05
Exhaust valves: 31.0 mm +/- 0.03
Intake timing variation: 60° (YG & YH)
Timing variator inactive: -25° (YG & YH)
Timing variator fully advanced: 35°

**It appears this cam information is incomplete, if anyone else has the specs; e.g. duration, LSA etc. These are rather important in determining dynamic compression.

Suggested octane from Maserati/Ferrari is 95 octane, thus I suspect we're walking a fine line with regard to maximal boost PSI. But it wouldn't be fun without some challenge.

I know you need the Maserati computer/code to reset the "service coupon" warning. Nobody has done it yet, so I doubt that any reasonable access to the ECU map is feasible. Anyhow, its easier to just boost and blow up a mustang 5.0 or something?

 

Oh, definitely interested in where this could go. Good information so far. Appreciate it.

I don't care for Mustangs, and seemingly like to do things the hard way. ?

But legitimately the shop in Ohio has the ability to tune them. They mention FI tuning also, however they could be encompassing all Maserati's within that statement.

 

Anybody with plans to attempt this on their 4.7?

 

Nothing formal. Just the mental masterbation component at at the moment. Trying to make contact with a proficient tuner not turned off at the prospect. If that lines up, then plans may become within reach.

I'm finding it hard to source basic knowledge, and rather surprised as I assumed this group would be heavy gear heads with such. Basic cam specs will be needed before I move forward, but I suppose Maserati may not be the most transparent for such information.

 

Would it be feasible to modify the 4.7 F 136 "Y" engine in our GT's, to the F 136 "F" spec which is found in the Ferrari 458 Speciale ?

This would increase horsepower from our 454 to 597 without supercharging.

According to what I've read......

 

sure, change the crank from cross plane to flat plane (increasing the rev ceiling), and add an extra throttle body, and change the inlet manifold and you're probably 90% there... exhaust is decent on the Maserati, but perhaps headers or sports cats may top it off. (don't forget to flash the computer to 458 tune as well)

 

The problem is that Maserati provides zero information, even less than Ferrari or related cars. I've been hunting around for someplace to get the ECU or TCU repaired with no luck at all; I called one shop that does Ferrari and Alfa ECU repair and they said "no Maserati, they don't provide any information on their programming so we can't fix those even though they are the same hardware units as the ones we do fix."

 

I'm sure there's USA based outfits, and Formula Dynamics comes to mind, but these guys are well rated for ECU tuning in the UK:

MASERATI Quattroporte 4.7 - DMS Automotive

 

Tuning may not be needed in the way you normally think. 16-18 years ago, way back, I had a 2000 Grand Prix GT with a NA 3.8 v6 which I installed an aftermarket supercharger kit (shaved 2 seconds off the 1/4mile, no bs). Tuning it wasnt an option just yet but a shop in Michigan made a supercharger kit utilizing a Paxton novi centrifugal supercharger. Hear me out here...

The kit obviously needed more fuel and being the NA engine it ran lower boost, much like we need, to run safely but yet get good power results. Matt was his name, and he was partnered with ZZP performance but was his own shop which I'm struggling to come up with the name. Without a a tune available they came up with a way to trick the mass air flow sensor into running larger injectors and correcting the timing, and in turn you could easily adjust the air fuel ratios to lean or rich the "tune".

I actually just dug and found they still sell the maf controller and their explanation is much better than mine.
https://zzperformance.com/products/mini-afc-air-fuel-controller

In theory, at least mine, this could be a solution for a low boost scenario, 4-6lbs or so should be a significant gain, no? Being that tunes are readily or cheaply available for such task.

Of course this is all speculation combined with what I ran on a much cheaper car back in the day.

It is a pipe dream and will not realistically work for a variety of reasons...I was just getting started with the exhaust, but I`ll add another...458 has dual VVT and M145 does not...so now you don't even have the wiring to run the second VVT solenoid let alone the software and a totally incorrect exhaust...Best advice...These are not 600-700HP cars...If you want that then you need a Corvette, AMG,Porsche or BMW.. These are nice cars, but expensive to modify...Best gains are from software, sports cats, and exhaust combined.. Even then you'll not see 600 hp....I honestly think some of these TV shows make the general public think you can just swap this and that and it will just fire right up..Here is the reality...It won't and there are a 100 problems that most people have not even thought of until they occur...You could swap engines like that in 1985....Jason

 

I know, let's put a V-12 in there from a Lamborghini Aventador, and supercharge that with some nitrous on board.

 

Why go so old school? I think it would be best to stick with Ferrari drive, but if you're going to go, go big! Just slap in the power train from the Ferrari The Ferrari. It's all Italian, so it should just bolt in and go :wink2:

 

I think we are getting off track here. Engine swaps are possible but expensive. As for supercharging, I am confident that I can get the hardware done. Its the tuning that would be an issue. Again if anyone knows a good custom tuner let me know.

 

I do this type of thing for a living and the only way a S/C would work is with a generic engine management computer. The existing computer does not have the ability to control a S/C and cannot be programmed in.

 

I'd be content with a 4.7 gts motor paired with my 05 F1 duo select transmission. Is this more possible than the supercharger?

 

that's essentially what the Granturismo MC Shift is... a 4.7 with the DuoSelect (renamed and re-programmed). This is easy as all the parts are available. Would it be cheaper than the the $20K roughly Novitec charge for supercharging? I wouldn't say so... probably about the same if you're buying new parts... 2nd hand you could piece a few together... (but hey, I'm the guy changing a murcielago from e-gear to manual...)

 

I have been on this forum daily for 6 years..So I have seen the topic of swaps, turbos, superchargers etc. come up previously.. Do you know how many I have seen completed?....ZERO....Do you know how many I have seen attempted?....ZERO..........Jason

 

I've had this fantasy of swapping out the V12 out of my 599 GTB Fiorano and into my GT, but my Ferrari mechanic squashed that idea pretty quickly. Even though the engine bay on the GT seems to have enough room and the chassis theoretically seems strong enough to handle the 600+ hp beast, the problem is the transmission. The ZF 6-sp auto is just too weak to handle the power and torque of the V12.


But it sure is fun to think about it.....imagine the sound of such a combo!:smile2:
