Whats the max BHP you should be pushing through a standard focus RS engine to retain its longevity? I heard 330-350 but I just want to be sure.

 

there are people that have had 400bhp with cams and a gt30 ect....

330/350 will be fine, and its a big BUT dont get a plug in remap for that power, get somewhere like jamsport to custom map it to the mods done, and its no more expensive either but will be alot better.

problems lie with charge cooler pumps, but i would fit a front mount at that power so wont matter.

and water pumps but if you upping the power by 120/130 bhp then fit a new cambelt kit and water pump for piece of mind.

 

Thanks I won't be able to go to Jamsport as I am located in the U.S. but the car will be going to a tuner and I won't be using any of the standard turbo kit. I was just making sure the internals will hold up.

 

350 American horses will probably be about 280 UK Stallions...you'll be fine

 

lol well im talking 400 english horses so if we are talking american then 500 is the limit lol

 

I'm just trying to hit the magic 300 whp. I want this engine to last a long time and I'm hoping for the time being its plenty for the track. The straight is a mile though.............? LOL
