How much can 2.3 T stand

[nissanman]

Hi Guys

I had to get a stronger diff with just 264AWHP. Compared to my Falcon Turbo (480rwbhp) these mazdas just dont hold up to much power.

stronger diff? or diffs? 195 awkw with a CAI and BOV?

is this the sort of system you men are on a bout

Strength of internals is one but not the only issue. Balance is key. And the more rpm you run, the more it is critical. You can have the strongest internals known to man but start slinging even a few asymmetric grams around at 5000+ rpm then you are asking for trouble.

Given that most modders here, including me, are bolting on power and upgrading fuel pumps to feed the new appetite and not pulling the engines apart to either strengthen rods or blueprint all rotationals, for obvious reasons of cost and effort, then we can expect what we get.

So I wouldn't be too critical of the engines themselves as they are doing what they were designed to do, and a decent margin above perhaps, but no more.

It's all then made worse by the fact that some factory ECU's (all cars) get the occasional brainstorm, and even Xedes and Standbacks seem to get occasional minds of their own, meaning that there is a risk of an unbalanced and internally weak engine, possibly at high rpm, slamming headlong into the solid brick wall of a mis-timing issue.

In this context, I believe that KMH001's comment above "there is no doubt that the problem is associated with map transition" is valid. Similarly, I don't think hydro-lock is a regular cause, it may be one, for reasons I won't explore here, but once an engine has shot its bolt, it's pretty hard to tell where all the oil came from and whether its presence is cause or effect.

Yeah that's essentially the same system that I was talking about. Do you know the history of the car in those photo's, has it been successful?

can not find the site it was on, but it was mostly used for drag racing,they also said that this system free up 20bhp more than stock pvc valves,pretty good mod in my opinion
