Paxton supercharger claims to make the roughly 405 hp Z06 Corvette to produce 580 hp. It includes the intercoolers and currently the Z06 has a compression of about 10.5 (the 360 about 11). Does anyone feel the Paxton can be fitted to the Ferrari 360 or others? | ||

"How much would a TT setup cost for a 355 running Twin T/3 hybrids? Pistons, IC, BOV, installation, down time, etc. What do you think final gains would be, 650-700? How much are the 355 blocks good for hp wise?" You're going to have to call Norwood to price that, but to do all that I would expect something like $25K. As for hp, they're are a couple 800 hp 308 engine out there, so 900 is probably possible, with 600 a lot more reasonable�..it�s all about how brave you are with your money. I'd figure about $15K-$20k to supercharge it into 600-700hp range | ||

"valve float happens around 18 psi" Good think I put stiffer springs in mine  | ||

50 shot NOS to spool her up and lower induction temperatures. trying to get the magic 500 out of it, (crank) might have to go to 16psi, valve float happens around 18 psi, will let ya know how it turns out! | ||

Paul, So 15 psi should get you to about 425 crank hp....then the nos, have they (norwood)told you to expect for the grand total hp? Looks great so far. | ||

Martin, I've never heard about a 360 kit, that would be cool though.... Paul, you're right, Norwood soes great work. Are you going 1 or 2 turbos? How much boost are you planning? And most important, when will it be running? | ||

Kent, Thanks....now I just need to actually make the kit....... I've changed it a little, the new version is very similar, but has room in the plenum for an inter cooler and is stronger, I think it�s now strong enough to deal with 60 psi or so just in case you ever want to put twin turbos and another inter cooler in front of the blower.....not that I would of course��that would be very very bad��. Seriously, the one in the photo, I used part of the OEM plenum to make. That�s Ok for a fabbed part since it�s their part I used, but I can�t make a new casting with ferrari�s name on it, it�s stealing. The casting will have similar ribs and a 4.5� chrome horse (OEM from a dealer) in the center. I think it will actually look a little nicer, but I�m still working on the prototypes (1 for me and one is going to Jeff D. in GA). Production pieces are probably 3-4 months away, but I�ll work as fast as I can. There�s a guy with a 2v injected 308 in CA on the list in front of you too, but maybe I can get yours out since I already have the design while I work out a system for the 2v cars. Why don�t you email me with a phone number so we can talk about exactly what you are interested in and what�s involved? | ||

Kent, Your stock cams are just about perfect as they are. The stock pistons are plenty strong for what you're talking about, but 6 psi with a roots blower is about all you'll get on 91 octane with a roots blower. That's not a flexible limit, if there is any doubt in your mind that you might want more, something like the QVs 8.6:1 CR would let you go up to about 8 or maybe 9 psi, but you'll loose a little power down low. A screw type blower will let you run higher boost with the stock pistons, but they cost more. Really it's about a $600 difference on the blower to go with a screw type, so you could do it for about $8100, I included other things in the other kit like a bigger fuel pump and throttle body, that you could live with out. The pump can always be changed later if you have any problem with the stock one. The reality is there�s a lot of flexibility on what parts are used and any package would be put together to order�..I don�t expect the demand would be more than 5-10 per year, so it�s not a high volume, take it or leave it deal�.you get to pick the parts that go in your kit so it matches your needs. The basic design is locked, the detail are not. I just listed what I thought would make good combinations to give people and idea of where I�m heading price wise. I am leaner toward making it so an intercooler could be added at a later date too, that basically let�s you go up 50% on boost is a little tougher to install.  | ||

Kent, check Mark's profile for a pic. I'm not an engineer, but I have the feeling his kit in the modest version would do what you want. I'm just waiting for him to 'go public' with it. | ||

My 3.2 engine is being rebuilt as I speak. I have an opportunity to prepare for moderate horsepower upgrades at this time. Hypothetically, lets say I buy Mark's Supercharge kit, low boost 6psi., which cam's and pistons would you recommend? I don't want to compromise driveability or reliability. Should I stick to OEM components to save a headache, or would this be a friendly investment? | ||

F***ing A Mark, spot on mate!! Now thats what i like to see.I my self twin turbo charged a Rover V8 engine and used warter injection as a secondery intercooler,had to design it all myself and build it but not after reading all the turbo and super charger books i could find,becourse there was no kits avalable and every where i rang advised me not to do it becourse of one reason or another,any way that was 3 years ago and the engine is still going strong in my other car and has evern been featured in several UK Streetmachine magazines.I for one am very interested to know how you did this coversion becourse i have to play with my F car over the winter months. Nice ine Mark.C | ||

Ken, Thanks, I spent way too much time on it. It�s a bolt on, the stock internals are very strong, the cams and compression ratio are well suited to boost also. It�s an eaton roots type blower and the car made 304 rwhp on 93 octane pump gas (the norm on the east coast) at 10psi, so maybe 350-360 crank hp. About a 50% increase, with 91 octane and 9.2:1 CR, I don�t think you would want to go over 6 or maybe 7 psi with a roots blower, so 40% hp increase, that�s the $7500 system. The plan is it would come with everything you need including the EFI stuff. The top of the intake will look a little different because clearly I can�t cast ferrari�s name into it, I�ll put on similar ribs, but leave an oval area in the center to hold a 4.5� horse, it should look at least as nice. With a screw type compressor you can run more boost, probably 10-12 psi, so 60+% hp increase, that�s the $8700 system. It would look the same, but uses better parts. I�m going to try to design it so an intercooler could be added in the future if you choose, but it might look cleaner if I don�t leave the room, but then I need make 2 castings, I need to think about that a little bit. | ||

That's a REALLY nice setup you've got there, Mark. Is it all bolt-on or did you have to beef up the internals as well? How much HP gain you getting out of that? | ||

There's a thot: Just "slapping on" a blower is probably a bad idea. But adding EFI, upgraded ignition, a new ECU (with knock sensor) and custom cams can let the car tolerate induction boost. But those mods will give you better performance by themselves, even without any blower. "Simple engine upgrade" is probably an oxymoron. | ||

Well, mine has had a blower for 2 years and about 15000 miles without any sign of a problem. But to your point, a 308 QV only has 8.6:1 CR, really it's an ideal candidate. The 3.2 has a 9:1 CR if I�m not mistaken, so there is still some room to play there. When you get to a 348 and newer, maybe a 40 degree F temperature rise is it all the engine will stand, so you're really limited on boost, but still that�s 3-5 psi without an intercooler from a screw type blower (only 2-4 root type) which should net you 25-35% hp increase. Add an intercooler and the number would be more like 6-10 psi for 50-60% hp gain. I�ve been extremely happy with my car since the conversion, but now it�s time for more. I�m building a new intake with a water/air intercooler build in and a much bigger blower, we�ll see what happens. Anyway, I have had a lot of requests for copies of the system an I am looking into producing them now. You need to convert to EFI at the same time, so a complete kit (308/328) would be priced around $7500 for 35% hp gain, $8700 for 60%, $12500 for 100% (intercooled). I�m sure a kit for other models could be designed, I�ll probably look in to it after the 308/328 project is finished. Then there�s the turbo route, the guys at norwood do great work and I�m sure they could help you too. | ||

What's strange is that whenever you go to a service center weather Ferrari or Lambo they highly do not recommend it and the reason for it is that the motor would not last and problems will happen and that is hearing that from tuners of these cars too. Now if you can afford to buy new motors very often then you probably can afford to do so and putting more boost to an already high compression motor would only cause detonation. Ever see one driving on a daily basis or even often enough? I haven't. It's usually show cars that seem to have them for bragging reasons. | ||

I'm very interested in supercharging my 3.2 Mondial Cab. Are there any successful & reliable results? I'd want conservative boost 5-6 psi. Will the stock engine handle it safely? |
