New 1.2 TSI Engine Exhaust near Firewall WTF
Hello :-)
I was with my friend at Skoda to make a test drive of new Fabia.
When I opened to see new TSI engine with 5 extra horses (110 total) from prev version I saw this
Did anyone noticed that exhaust side moved to the back to the firewall??? WTF?
May be there is some magic engineering involved, but how it could be better from when it was in front of grill and better cooled with air flow and less heating front cabine part?
Again. Exhaust part (turbine + catalytic converter + pipes) with all high temperature (above 300C) moved to less ventilated part. Let's burn more oil! :-) And more to add, it has AC hoses there not heat protected.
I don't get it... It has programmed potential issues to owners and more profit for garages...
Old setup was much better in terms of logical and physical thinking.
Update (2015-10-21)
I have to note that I talked with owner of SEAT Leon Cupra R after this post.
He also has the same layout with exhaust and turbine near firewall. That's not crappy 1.2 TSI :-) that's 2.0L TSI in stock 265 PS and 340 Nm but now with stage 2 - 335 HP and 450 Nm! No issues. He suggested me that it makes sence in terms of getting exhaust closer to tailpipe, no need to run under the engine block.
