Thanks Ernesto. Your emissions testing routine not an option for me, but certainly seems to work. I'm going to try the Tubi filters and a new exhaust. | ||

Mine is also a street car, and here the gov't also has emmissions inspections. I usually get away with paying off the inspector and he tests my Pathfinder instead. Otherwise, just reinstall the cats for inspection time (a very time consuming procedure if you dont have a lift/proper tools). I dont remember what brand of air filters I have, but they are the ones made (or distributed) by Tubi. As soon as K&Ns become available, I will switch to those. Ernesto | ||

ok. what brand of racing air filter? Can't get away with no cats since this is a street car and I'm in NY. Which exhaust to use? | ||

Yeah, Manu. I have the exact setup you mentioned, except of course I have the Tubi muffler instead of straight pipe. My next thing is to eliminate the resonator/silencer on the air intake system portion that is inside the c-pillar area and just put a straight pipe (like the RM Racing Kit). I have yet to see the Tubi thermally insulated Sport Manifolds (aka headers). How much do these run? That would be interesting, but looks like a difficult job. Ernesto PS. I like that quote: "The admirable, power-crazed Ernesto." I shall be using that as my slogan from now on! | ||

Sport Test pipes + Racing Air filter + TubiStyle Tube-Only Muffler = ~+35bhp With no restriction on intake and exhaust flow the car will be MEGA loud and have a load more grunt. That is NOT a standard Tubi Sport Exhaust - it is TUBE-ONLY which means it is a set of pipes a'la Formula 1 - MAXIMUM FLOW race-car style. Not even the admirable, power-crazed, Ernesto has this system on his car. You can get the ECU reprogrammed but this will likely increase Petrol Octane Sensitivity. I know a German Company..... I'll try finding a link. You could also try Tubi Thermally Insulated Sport Manifolds. | ||

how about extrude hone intake runners. Has anyone ever had this done on any car? Seems like it would be a simple bolt on mod that could get you a few ponies and still be technically stock. This combined with a tubi headers/exaust/cat dropouts/free flow intake would make a nice power gain. I was going to have it done on my NSX but I sold it. If I remember correctly it was about $600 to have it done. Ferrari may already do this from the factory, I do not know. Chips might make a small power gain (maybe 5 peak HP) They just remap the fuel injection + timing. They dont work so good on natural cars, on turbo or SC cars they work great because you can turn up the boost+increase fuel and make a good gain for cheap $$. | ||

> I had a thought, I wonder if removing the airbox alltogether will > give a gain, or loss in ultimate power? Assuming you handle the air flow sensor problem, I am fairly certain this would be a big loss of power... with the whole exhaust system in the same compartment, you would be sucking in really hot air. The setup it has now is a very big pipe with direct feed from the outside. The only restriction there is the air filter. And the only other *possible* improvement will be heat shielding to further reduce temperature of the incoming air. Though its been argued that the air moves so fast through there that it really doesn't heat up much. And given Ferrari painted it black and could've easily painted it heat-reflective silver... I suspect the latter theory may hold true. | ||

I had a thought, I wonder if removing the airbox alltogether will give a gain, or loss in ultimate power? (ie, expose the individual intake horns themselves) are they tuned for power peak free-resonance, or in that airbox? (uh, this would require some way to 'fake' (or attach one and multiply by 8 the value) of the MAF and other sensors... Wish I had a track 360 to dicker and tune with :D) Best! Ben. | ||

I thought the fronts were 225s. Either way, a mid-engine car dosen't need a whole lot of rubber up front, there just isn't a lot of polar moment to move up there. You reach a point where more just hurts steering effort generally. My car runs 225/40/18 front, 265/35/18 rear. I could use more in the rear, but the front is just fine, nice and accurate. Full Tubi system will get you a few ponies, but you'll probally not even be able to tell. Really, there's not a whole lot one can do, the nearly 400hp motor is already near it's peak in tune. You start to consider a custom turbo system, or a displacement (bore?) boost possibly, and the cost spirals madly, and reliability gets a big question mark. One option may be the 360GT parts, good for another ~40hp. Up to you to source though! | ||

Solly, whats it like with such thin front tires? Obviously they do the job, otherwise Ferrari wouldnt use them, but they just seem really thin. | ||

I think I'm going for the following: 1) Freer-flowing exhaust 2) Freer-flowing air filter, with heat shielding 3) Lightweight wheeels with 335's in the back (instead of the stock 275's) and 275's in front (stock=215's) I'll let you guys know what performance gains I got. Should be done in a week or 2. Happy 4th everyone!!! | ||

Was curious: I have known well engineered vehicles that the manufacturer designed the transmission and the rest of the driveline for the horsepower that the engine put out. The manufacturer did not want the added weight of an overbuilt transmission. Would the 360 and other Ferraris be like that? Or can the rest of the systems take added HP? | ||

I, too, am interested in HP increases, if possible. Another easy mod that added HP to my M3 and should add way more on the 360 would be heat shielding the air intake... as it comes, the 360 is basically set up to heat the intake air really well (a long intake run through a hot engine bay right over the exhaust system, using black metal surrounds to absorb that heat)! However, I suspect you'll see maybe 5hp from exhaust and 5hp from intake modes. Not a whole lot on a 400hp car... Ferrari would have done most anything easy or anything that made significant HP. For keeping those pesky Diablos away on the track, I think the #1 mod is wheels and tires! The wheel wells will fit HUGE wheels. Put 10" on the front and 13" on the rear... shoe them in R-compound tires... and you'll be able to put the full 400hp down way earlier in the turn... with enough exit speed, the Diablos HP advantage won't come into play except on reeaally long straights. My guess is that the next best mod is reducing unsprung weight. You can lose 6-12# per wheel by going with lightweight forged wheels and lightweight rotors. That's worth 15HP, using typical rules of thumb. | ||

I spent about 5k and put a supercharger on my 308, it gained over 60% hp and torque. The 360 has pretty high compression, but I've got to believe you could run 4 or maybe 5 psi. That would buy you about 25% gain in HP and torque across the board. Turbos and nos are good too, but not as user friendly as a supercharger. | ||

If the 360 engine is anything like the 3.5 engine, the major limitation is the exhaust. If the tubi gives more power, you might want to think about having someone rework the exhaust port. It really worked on my 355. Art | ||

The guy with the chipped 360 that was mentioned in the Forza article was at the San Diego Ferrari Owners Club show. His name is Steve Bischel. Anyone here know him? Is he here on FerrariChat? I think a lot of us would like to know what mods were made and how he got his hands on those chips. | ||

I did the Tubi exhaust and cat pipes, plus the air filter replacements - and you can definitely feel the car is faster through the rev range, though more so on the top of the RPMs. The only thing you may regret is the higher noise levels, but if you dont care about this, then it is the way to go. The only other things I would do are Tubi headers and a unrestrcited air intake system (ie no silencer). I dont think a reprogrammed chip would add that much hp though, but would definitely try one out if I found one. Ernesto | ||

What's the best exhaust? What's the best free-flow air filter? Does it fit in the stock airbox? If not, easy modification? | ||

See if you could get your hands on some 360GT(not Challenge)parts and software. They're supposed to have 430HP+. An article in Forza #39 mentioned a guy in San Diego with a modified 360 with factory custom-ordered engine chip. The local dealer here does not know anything about the special engine chips but is looking into it. | ||

Im sure you could safely shoot a 100 shot of nitrous. I dont know if anyones ever done it to a ferrari, but the engine should be strong enough. Its just a question of wether or not the fuel system can handle it. Spraying without enough fuel is a good way to burn those expensive pistons, which will require an expensive rebuild. | ||

I did. It is incredible. Sticks like glue in the turns, but needs a few more ponies on the straights to keep pesky Diablos off my tail. This car really could benefit from wider tires and 50 more HP. It would then be unbeatable in expert hands (not me). | ||

Steven: If there were easy dramatic gains to be had I think Ferrari would do them already. You'll get small gains from high flow intake and Tubi exaust. Other than that I wouldn't waste the money on anything else. | ||

What can I do to pick up some more ponies on a 360? I understand new exhaust may help, but heard that Tubi was mostly for sound, not additional performance. Any other exhausts out there that will give me some more HP? Any other easy fixes like air filters, chips, etc? Don't want to modify engine. What's a realistic power gain? |
