Hi fellow Renaulters, I come seeking guidance and assistance.
I race a Formula Renault Eurocup car and am looking for some more power. I have pretty much decided on fitting a turbo conversion and am in the research phase. I’m hoping I can glean some information from you lot.
The car runs a very slightly modified F4R 832 engine (which I believe was found in the Clio 200). Its modifications internally amount to no more than some minor head work. Externally it has a dry sump kit and a different intake and exhaust manifold.
It’s managed by a Pectel SQ6 ECU which is more than up for the job.
Gearbox is a 7 speed Sadev sequential.
The car currently puts out approx 210bhp and in an ideal world I would be looking for about 260-270bhp with nice flat torque. However, the numbers are only part of my requirements. As a 500kg racecar driveability is paramount. A laggy unresponsive engine -even one with more power - would likely hurt my laptimes rather than improve them. Also, I need to retain the 7500 redline for gearing purposes.
I see many people recommend a set of cams but then list redlines of about 6500rpm. I’m guessing this drop in RPM is as a result of the cams ??But maybe they’re needed to pump the turbo?
My exhaust after the turbo can be ran unsilenced, with no cat and end immediately.
Packaging wise I think we have a plan there that works so I’m just trying to get info on matching cams, turbos etc to suit my requirements.
Any help appreciated.
