upgraded injectors
mike_sekinger replied to alanlambert's topic in Esprit 'Project & Restoration' Room
Hi Alan, I`m pretty sure those injectors are not going to be big enough to run as your only source of fuelling. They are only marginally higher flow than the stock injectors at 267cc/min and are typically used as replacements for the stock injectors when keeping the secondaries in place (secondaries are 550cc/min) Of course it all depends on your power target but even at 400bhp, you would need something up around 8x 360cc/min. There is a rough injector size calculator on the RC Engineering website RC Fuel Injection > Technical -
Just be aware if they are re-manufactured.

PNM offer a flywheel refurbishment service. Yes, the clutch mounting needs to be machined to retain the correct step. PNMFLY918 Lotus Esprit V8 Flywheel Re-surface & Grind Service (pnmparts.co.uk)

There is a linkage between the throttles and also a balance pipe across the plenums. The arrangement will be different with the tubular manifolds and BorgWarner EFR turbos. Andrä managed to get some GT2871s installed by changing the compressor housing orientation and adaption of the wastegate flap on one side. I`ve seen this done on other 918s before.

These images represent a massive amount of work and pioneering developments. Great things yet to break cover. -

Maybe Father Christmas will bring us a small update.... doesn`t seem like too much to ask for. -

@ProAlloy-Alex please can you confirm that you have received the compressor ducts. -
Just got an update on the plenum fabrication from SMD Racing - coming along nicely. Matching of the port openings and inlet manifolds still needs to be done. Test fit on arrival and once the clearances are measured, the fuel rails will be fab`d up. Depending on the additional clearance between the plenum and the motorsport rear deck, an additional space might be used to bring up the torque. This set-up will be fitted once the engine is run-in and ready for the Motec update for 8x larger injectors.

Back out in the cold today. Got the original lower valance back and installed. The front carbon arch section fettled and fitted. I will not be using the original front splitter, as it is forced to sit too high for road car usage. I`ll be coming up with a decent compromise that will allow me to run as the desired height for the road.
