would an N/a be able to handle the same rpm? around the 6000 mark with a superpump as the only mod?
N/A would handle high rpms better, because boost doesn't cause valves to float as much and there's less load on the pistons.
mechanical heads have any advantage?should have i suppose...
if so what the rpm limits seen on these engines?
Factory red line is 5100 for the 1.6TD (from memory)
from the manual:
1.5D redline 5200
1.6D redline 4800
1.9D redline 4600
all are as the 'lower bound' for max rpm setting. upper bound is +250rpm... i think theres a fair amount of variation in this ;-)
but im sure they have been safely pushed beyond these numbers.. I also think that mechanical heads would have some advantage of just being.. tougher? maybe a beefier made head..? i really have no idea.
In dont either this engine is new to me Im still learning it. But it stands to reason the beefier it is the more abuse it would stand up to. Any one have any idea of what a safe higher rpm cruising range would be on an aaz. Just dont want to go all out and push it to hard with out knowing the facts first.
I know in gasser engines mechanical lifters are favored due to no "bleed down" at higher revs causing lower lift and duration. I'd assume the same would apply.
No idea how high it revved, but our 1.5 IDI survived a starting fluid run-away running for what felt like forever but was really maybe 20 seconds. God only knows how high of revs.
