New Dry Sump for "New Evo"

We have a new dry sump system for "New Evo", the Tilton Interiors/Insight Motorsports Evo IX RS, which will make its motorsports' début at the World Time Attack Challlenge at Eastern Creek, Friday 6 August and Saturday 7 August.

As I mentioned in an earlier post, Insight Motorsports Dry Sump Systems, we developed our original dry sump system and tested it on the racetrack, bolted into the original Tiliton Interiors/Insight Motorsports Lancer Evolution IX RS, which we now affectionately call "Old Evo".

To be fair, Old Evo and New Evo are the same age and the exact same model apart from the exterior of the former being white and the latter being silver. New Evo is just more extreme. We have taken lessons learned in the heat of battle and engineered them into our new designs.

Take for example, the dry sump pictured fitted to New Evo:

The kit includes:

• Timing cover with internal pump elimination and braced sprocket system
• Billet sump assembly with stainless steel cap screws
• Peterson R4 high volume 4 stage dry sump pump
• ATI balancer with spline drive assembly
• Goodrich G-Line Kevlar line from sump to pump
• Drive belt and 50% drive sprocket

In 16 days, the Tilton Interiors/Insight Motorsports Evo 9 RS will be competing in the Pro Class of the 2011 World Time Attack Challenge, running the Insight Motorsports dry sump system. We are proud to be able to supply you with race proven technology. The complete kit is available for $7950+GST.

Systems for non-Evo applications are available on request. For example, Scott Kuhner has fitted the dry sump, with a Peterson 6 Stage R4 Drag Dry Sump Pump, to his legendary Stanza. Already famous for a best of 9.4 seconds at WSID, the Stanza will hopefully be making her comeback soon, although she was still semi naked last time I photographed her, with her 4G63 (i.e. Evo engine) and bird eating turbocharger proudly visible.

Evo IX: Stock versus Turbo XS Exhaust & Flash Tune

I know that there is a bit of interest out there about the sort of gains which can be made on the Mitsubishi Lancer Evolution engines with just the fitment of an aftermarket exhaust. In fact, the gains which can be made are quite substantial. Moreover, I have proof.

Here is a comparison of a stock Evo IX engine and the same engine fitted with a 3 inch Turbo XS exhaust and a flash tuned ECU.

The latter combination yields a 26% gain in maximum power. Most notable, however, is the massive gain in torque across the entire rev range. On the street or on the circuit, this would result in a much more flexible and useable engine.

Flex Fuel Testing on Mitsubishi Evo 9

These are the results of preliminary testing of our Flex Fuel test car, a Mitsubishi Lancer Evolution 9.

So what is Flex Fuel? It is a system which allows you to run E100 (100% ethanol) or 98 RON unleaded petrol or anywhere in between on the same car with the same fuel system.


The test car is an Evo 9. In order to manage wide range of parameters of the flex fuel system, it is fitted with a wideband O2 sensor, fuel composition meter, Insight Motorsports Evo twin pump upgrade, ViPEC V88 ECU, Xspurt 1000 injectors, fuel pump controller and digital individual cylinder knock control.


The test engine is an 124000 km old Evo 9 engine (as per the photo) that is totally standard mechanically apart from the aforementioned support system improvements and a Turbo XS 3 inch exhaust.

Once more road testing with varying levels of fuel composition is completed, we will replace the wastegate actuator since it has been limiting the boost due to its age (original turbo remember). We expect the engine to run about 20 psi, which from our experience should produce close to 260 kW ATW on E100.

The next step will be to install an adjustable fuel pressure regulator to allow for an increase in fuel pressure. This will allow higher injector flow capacity and therefore more boost.

Flex Fuel kits will be offered from early 2011.


This particular car has a 700 hp race engine ready for installation and will also be setup with Flex Fuel.
