F355 Twin Turbo, now in US/EU

Every engine is designed to take more than the rated horsepower and torque. I have seen motors take well over 3 times the rated horsepower, such as the Supra motor which takes well over 900whp on a stock motor. Or the Lancer EVO8, which can make over 600whp on stock internals, more than twice of the stock rated horsepower. So to say that it would be designed only for 380hp/270tq would, honestly, be a mistake.

And given that Ferrari does put a significant amount of engineering into their engines, this is really no suprise. The suprise though, is the clutch. To have the clutch withstand the power with no slippage really is a testament to the standard at which Ferrari builds it cars.

With the drag 0-60mph times, the 6psi kit had a 1.7 sec 0-60' (not mph) time. The 13psi kit (which ran in the video) had a 2.2sec 0-60' time.

 

Steve,
The original tester car for the TT kit is still runnning all his original parts. He has abused the car and driven it extremely hard. From drag racing to street races, he runs the car very hard and does not baby it in any form or fashion. It is also driven in traffic with no adverse effects.

Increased power and pressures do put more pressures on the motor. But because of the superior engineering of the turbo kit and the motor, those pressures are within the specs.

But you are right, anyone can destroy a motor.

 

In addition to the info above, anyone can blow a motor, even a naturally aspirated one. Pushing it into redline all time, things like that.

As far as acceleration for most daily driving, the 0-60mph time for the 6psi kit is near the exact same for the 13psi kit. It is 3.3-3.5 seconds. Still better than any car you will almost ever run into. The reason the times are so similar is that the 13psi kit has much more wheelspin than the 6psi, and actually, the 6psi kit has a faster lower end than the 13psi due to the less boost (meaning lower spool time for max boost) and less wheelspin.

On the drag strip, the 0-60' time for the 6psi kit was 1.7sec and the 13psi was 2.2 seconds.

 

Quote from the F355TT Owner-Ton

 

We have talked with several people about being the validation car for this twin turbo kit, with no takers as of yet. We are still looking for a car to put this on. For those who take their car's on track days or "rallies", this kit will surely perform.

If you have any questions or comments whatsoever, please post up and we will answer them ASAP.

 

Thanks. Although we were not driving the car. I have driven 11's before, and I have to prefer my cars to be able to corner fast than go fast in a straight line. You would have to talk to Ton about the misshifts

 

We would like any F355 Owners to consider this kit. We have talked with Modified Luxury & Exotics to do a press release, tech article, and feature article on the kit. We have already sumbitted our press release to them, and it should be in the magazine in the issue coming out or the next issue.

 

I will respond as open as possible (and I apologize for not seeing your questions until now)

1.) As comparative for the 6psi vs the 13psi, the difference is mainly the horsepower. With the 13psi kit, if you track the car, this will really wake the car up and get you around the track much quicker. As far as for the 6psi, if the car is a weekend car, but you are looking for a little more "oomph", this will take care of it for you. Or if you are looking just to have a fast car, without spending the money on a 360, this will take care of it.

2.) When Nizpro was designing the kit, they did not pick 2 boost levels and build off that. They built off a low boost point and increased the boost from there to get maximum performance possible, while still keeping driveability. The 13psi kit would be a beast of a street car and, if raced, would take down most anything, with proper driving skill of course.

3.) The sound is one that is unique to the Nizpro kit, and the exhaust has been designed for a turbo car. Exhaust for a naturally aspirated car requires specific backpressures to ensure exhaust velocity. But a turbo car is the exact opposite. The turbo requires as little exhaust backpressure as possible. In fact, the ideal exhaust for a turbo is none at all, but that violates every exhaust statute in the book, so that is a no-go.

4.) As far as how the engine takes to the boost on the pre-97 models, Nizpro has not run into any issue so far with the tuning or performance gains on either the 6psi or 13psi kits. As far as engine life, once again, that is up the driver. Keeping the car to red most of the drive will put a motor out the door quicker than running it hard every now and then. But for shortened engine life, I really do not see it as an issue, as I have seen cars put a turbo on at 130K miles, and drive it another 75K miles with no issues, and selling it.

5.) As far as other components needed, this kit has been running on the stock internals, clutch, and the tester car just got new tires. Nothing is needed to be replaced as the kit comes, which is suprising to me, believe me. But brakes are recommended to increase stopping ability, as higher speeds are certainly more capable with this. With regards to body work, Ryalex Design and my company have started to talk about a Total F355 package to include entire new body work and the 6psi turbo kit. But that is months away, as they are developing the F355 body now.

6.) Pre-Lubers (for the oil) are a good thing in a turbo car to prevent heat damage to the turbochargers. But necessary, no. Only a select few cars that I know of have pre-lubers. However, one thing that is highly recommended is a turbo timer. It is a count-down device, so that when you park the car, you can remove your key's, set the E-brake, and walk away. This allows the oil to continue to cool down the turbochargers to prevent the oil from coking inside the turbo's and preventing subsequent damage. They are extremely affordable and is great insurance for a turbo car.

7.) As far as why Ferrari owners are hesitant, I will be honest that it is not just Ferrari owners. All car owners are hesistant to put something aftermarket on their car that has yet to be proven in their market, because who wants to destroy their car? But after performance is proven and documented, with no failures, people to tend to become more acceptable towards turbocharging their F355's/cars. I have talked with several F355 owners, and some are tired of souped up Mustangs beating them or racing against a 360 and losing. And while they do agree that it is a worthwhile item, it has yet to be proven in the US.

Another issue I have noted is CARB exemption. Most owners I have spoken with do not want their car to become illegal after installing the kit. So I did some research to find out what really the CARB E.O. consisted of. Basically, so long as it can be proven in the installation manual that nothing is left out that came from the factory (such as hoses, etc), and can be tested to ensure that it does not significantly increase harmful emissions, a CARB E.O. is granted. But the CARB does not do any testing on it's own. I have forwarded all the information about CARB exemption to Nizpro, which can do testing to determine the exhaust output of a stock car and a TT car.

Other answers: Some have asked about warranties. The turbo kit comes with a 1yr/12K mile warranty, whichever first. Everything is covered except the turbochargers, which are covered under the Garrett warranty, which is a minimum of 1yr/12K miles.

As far as how the tester car is going, it is still going incredibly well. The car is w/o hiccups, and the clutch is purportedly indestructible (not really, but the car is running as strong as ever).

For those with international magazine interest, the magazine, Motor, will be sending a V8 Supercar driver to test out the car next week. Some have said the performance is above that of the V8 Supercars.

I hope I have answered all your questions fully enough. Should anyone have any questions at all, please do not hesistate to contact me. And I promise I will respond quicker than I did to this post

 

Here is an update on the kit, which we just recieved. The kit has passed the 8000 miles mark with no failures, no detonation, no clutch slip. His daily driver F355 is still running great.

Nizpro believes the exhaust sounds amazing as is. With regards to fitting another exhaust such as a Tubi or Capristo, that is not possible as the entire set up is totally custom. However, more baffling can be added without a problem, for more sound.

For those F355 owners who just want more performance, this is the best way to get it. Ask any question you have, and we will respond as quickly as possible. We have yet to have a owner take the plunge, and are offering a initial purchase discount, and all we request is an honest writeup of what you think of the system and the performance.

We have talked with Modified L&E, and the kit will be in the next product release section of their magazine.

 

I meant to include this in my last post. I know most everyone is skeptical about the clutch, so I have contact Tilton to see if they can make a clutch that would be able to handle the power. More info as it becomes available.

 

I met with Jason Heffner from Heffners Performance today and he is willing to do the installation. Heffners Performance has the quickest Twin Turbo Dodge Viper, and is currently building a Gallardo Twin Turbo for a member on this board, G-Force.

 

pm sent.

 

I have sent an email to Nizpro and will send a pm to Ton to see if we can get a leak down test done, or see if one has already been done. I would think that with the thought and engineering done with this kit/car, a test would have been performed many times throughout the testing phase of the kit.

As soon as I find out the test results, I will post them up.

 

Peter, I realize that you are in argument about Tony's statements, but please do not clutter this thread with contention. Thanks!
