exhaust manifold is integrated into the head and water cooled
electric heat management
twin scroll turbo
lots of weight reduction, for example plastic sump.
What I can’t quite see is the paths of the valves, and how the exhaust is split between the sides of the turbo. No what would be very cool is if they can lift one valve at low rpm like the K20A inlet to improve gas velocity and direct it all down the tighter scroll. Then open up the pair when they want it to breathe.
Anyway, have a read if you’re into that kinda stuff.
3mm block wall sounds scary
water pumps just became scary expensive and no more diy
plastic sump which includes main bearing covers also means baffled sumps become more complicated
cool tech but why does progress continue to go in the direction of throw away after use/damage. I do love the friction reduction (nano) technology though
These new engines though are all about emissions. I wouldn’t want to touch an engine that has a built in exhaust manifold, how do you go about bolting a huge turbo to that. hahaha
The 1.8 20v engine lost tuning potential over its life cycle. The head on an early 1.8t golf had huge ports. The later engines had much smaller ports for emissions reasons. Thankfully there are a gazillion big port heads in scrap yards that mean MAHOOOOOOOSIVE power 1.8t’s are still doable. That engine was then replaced by the 2.0 TFSI engine and again that is harder to get big power from that a 1.8 20v. Its all just a sign of the times i guess.
Lets be honest though the manufacturers must hate the after market. I have heard it said that Lotus put pressure on the LOT race series to outlaw non OE engines from certain series as they wanted ‘Lotus product’ to be doing all the winning. Thankfully LOT didnt totally bend over as there are still a few NA honda cars racing I believe
Modern engines seem to be more self contained and too full of electronic wizardary. I think tuning in the future may be more about cracking OEM software - actualy that’s already here.
