Rebuilt my F355 engine

They claim 490hp with full kit and Motec.

 

Where did you get that info from I been searching. LOL I think the price is fair then, if there claim is true, more hp's then a F430

 

Sent them an email and that was reply

 

Thats a fantastic gain for a relitivly great price. I cant get the dam thing out of my head after seeing the kit posted yesterday Wish i had not seen the dam thing now. I do hope they provide a detailed write up with dyno results and video of the kit fitted.
Weres Forza magazine Once i have seen that then they will have a buyer here.

 

Other than the adjustable cam pulleys ...... I wonder if the cams have a radically different profile from stock or if it is a timing change to bias a higher RPM torque limit? ......... which begs .... how much faster are they spinning the motor? What kind of fuel and engine management is required?

Because ........ starting with a stock 380hp 3.5 .......... HP increase from the larger 3.859 displacement increase alone, only gets us to 418hp ....... the increase in torque from the longer stroke is not enough to get 490hp ..........

490 hp from a 3.859L = 126.97 HP per liter .............. which is approximately where the new 458 is per liter ...... .............. IMO there 'has to be' a few more parts/mods than what the picture shows to get 490 hp ............ if there isn't any other parts/mods ...... then 'pure magic' is the only explanation ........

I don't think you will be alone buying this kit.

 

I think there claim is very high so I'm not going to jump the gun. I really want to see dyno sheets and videos. Many people have made claims and never backed it up so I'll wait for the proof. Also we don't know how the engine will handle for everyday driving.
