S85-EVO Program

Swipe right for info.

Reach 125hp/liters and beyond.

I have documented dyno performance gains and the variables that come into play.

Increased RPM limit to 8,800 RPM.

Peak power is achieved +/- 700 RPM over original. To do so, we use a lightened, uprated valvetrain.

Maximize performance with torque multiplication.

Higher rev limits enable shorter gearing while retaining the original top speed.

Optimized engine maps.

S85-EVO tuning solutions were developed on the road, and fine tuned on the dyno for all driving conditions.

Program fundamentals
Complete S85 cylinders head service.

The S85-EVO Program is based on a core exchange service.

Core S85 cylinder heads are inspected, cleaned, machined, refreshed and upgraded with the components required.

The heads are delivered with the new camshafts bolted for transportation purpose. You will need to transfer your original camshaft hydraulic followers and VANOS components .

Upgrade your final drive ratio.

Maximize the benefits of increased power at higher rev limits.

FAQs

No.

Yes. Contact me to discuss options.

Yes - dyno tuning will be mandatory.

The performance figures were achieved starting from a Full Bolt-On (FBO) basis. It is highly recommended to have the V4 long tube, equal length headers and the CSL Competition intake installed.

SXX-EVO: High duration camshaft programs.

In 2023, I set out to empirically prove, or disprove an hypothesis: could we reach 125hp/liters on naturally aspirated S54B32, S65B40 and S85B50 engines?
