I'm getting a remap for the Compact which runs an M52 with M50 manifold. One of the potential benefits of a map is I can choose the upper rev limit, which I believe is 6,500rpm standard. 7,000rpm seems to be the general recommendation before it becomes 'unsafe' but wondered what people's real world experience of upping the limiters and then spending all day bouncing off them was? Do they just love it or is it worth playing it safe?
James, when I spoke to Enda Ward @ EndTuning, he said 7k is normal, but some people go for more, but this was for my track car not a drift one, so won't be on the redline anywhere near as much, maybe fire him a message, lovely guy (or just get him to map it, even better lol).
cheers guys. might go for 7,200 if 7k is 'normal' What's the actual limiting factor in how high a standard Single Vanos M52 engine will rev?
My M50 is upped to 7.2. I will be having the same on my M52. In all honesty I don't ever get up to 7.2 when doing skids. It just allows for that little bit extra to play with and enable's you to change gear that little bit later, without having to bang it off the limiter every time.
I know of people that have. It takes a while unless you get valve bounce. Standard on a M52B28 is 6250. 7k should be enough
i had mine put to 7 as there is no actual gain past 7, it flat lines or falls away, 7200/7800 sounds great on paper, but you wont be able to gain etc.
from what I've read by scouring internet forums, most over-revving engine explosions have been the result of a mis-shift and have been when engines have seen more like 9,000+ rpm I'm not after a load more power, just more range. Should have the remap sorted by the end of this week
