Looks like a challenge car! Love it!

PM sent. Our website seems to be working. Anyone else having problems?

FABSPEED: Ferrari F458

almost 70whp gain on exhaust and tune on a NA car sounds almost to good to be true! Excellent work!

[Mahzari]

630 crank horsepower... Oh my god, what a beast

I hope this doesnt sound like an attack on you but the claims you made in your post are completely unsubstantiated.

Hi David, I beg to differ. Chassis Dyno are very unreliable, there are dozens of factors that can affect the results. The other problem with them is they never accurately replicate actual loads from driving on real roads.

You are suggesting a basic tune + exhaust on an high strung NA motor that is already operating at near maximum efficiency is able to add 80 crank hp? So why aren't you on the phone with Ferrari engineers telling them what they did wrong, as you are able to increase power by 15% without raising revs past 10k on this engine. On your base runs you are suggesting this car is making 450whp, implying 25% power losses on an extremely efficient drivetrain? 450whp in the italia which is quite a heavy car would not be trapping 130mph+ as many users have done(not just magazines).

It's almost as if your base run is completely underrating the HP of this car(or something is wrong with the vehicle itself). Scuderia's are laying down 450-460whp on these 20second dyno runs. That or you really are the best tuners in the world and should be saluted, managing 15-20% hp gains out of the best engines in the world without any forced induction I may add??

very nice work!! seems very complete

You have to keep in mind that the Ferrari engineers have to obey emissions regulations which is probably why they bottleneck some of the power.

And further development of the same engine. Scud version etc that will have more power.

But i say it again. 80-90crank hp is very good for tune and exhaust on NA car. almost too good.

Are you suggesting you are gaining around 100 crank HP on a NA engine from an exhaust bolt up? I understand Ferrari isn't using the best exhausts due to the emission + noise regulations, but 100hp gain on none boosted motor? Yea right. Not believing that unless you got engine dyno sheet(20k chassis dyno is SUSPECT).

Hello Ramius,

No offense, but the info is clearly written in the post. We saw a gain of 67 whp with Fabspeed headers, catalytic converters (200 cell by HJS), sport mufflers, and ECU tune by Evolution Motorsports. It is a big gain... even bigger than expected, but certainly within the realm of possibility. Please let me know if you have any other questions. Thanks.

Jeff
