Settle an arguement.
 

Would just like your input on this statement. Most notably the 25psi part.



sorry man, but no matter what you drive, once you start moddin it, it's gonna run the risk of blowin up. there's too many stories floatin around about the rotary that scare ppl off, if done right and cared for, they can last plenty long. look at ernieT, he bought a brand new, reman mazda motor, no porting or any work at all. didn't run a break-in or nuthin. took it straight to the dyno at 25 lbs., running consistent 10's, and been running it for over a year like that. sounds fine to me

And sorry for not knowing who ernieT is. I never visit the 3rd gen forum.

thats just about right although i dont think his engine is gonna make it pass the 100k mark...

So I can go buy a reman, strap a KKK on it, turn it up to 25 psi out of the box, and itll just run 10's all day long?

If everything is tuned, etc... There are other mods that go with that turbo to make a 10 second pass happen.

ErnieT knows what he's doing. If it was that easy everyone would be doing it. :)

Im not saying theres not other mods.
Im just going by the above statement.

A reman engine
No portwork
No break in
25psi on a KKK

I will say that the car would be "capable" of running 10's. However, to be correct, ErnieT was running 20lbs of boost:

Here's where that 25lbs of boost came from:

For the 3rd time, Im not talking about anything else on this forum. All I know is what this person told me which is what I said in BOLD in my first post.

Calm down tiger.

I'm clarifying the situation. ErnieT was running 20lbs of boost. The person who wrote that original statement mixed up ErnieT's commends.

Yes, ErnieT ran a stock ported motor with a Stage 2 KKK single turbo at 20PSI and got into the 10's.

I don't think it's a fair assumption to say "all you need is a reman, a big single turbo and run 20 PSI to get into the 10's.".

lol dont worry. Im calm.

Im just saying forget everything you know about ernie and read that post.

Its saying that I can take a reman motor out of the box, dial it up to 25psi, and run 10's all day long.

Im asking if you all agree with that statement or not.

Yes I do agree, to some extent (I don't agree that you will necessarily hit "10's all day long", but dialing up the boost on a reman, sure).

Most remans are not "new" motors, so I somewhat agree with the people that say remans do not require a break-in period. However, I do believe that it depends on how long you want to have the engine last. If you aren't concerned with having the engine lasting 100k or longer, sure, dial up the boost and tear it up.

I think an important part of that formula is missing. This is probably more correct:

Take reman out of the box, drop it into a car that has lots of supporting hardware and many hours of tuning with a similar motor, dial it up to 25 psi, and run 10's all day long.

But you might have to tow it home at the end of the day if something goes wrong. :)

I also think that there is value in braking in the motor. If you have new apex seals and new rotor housings in the reman, you could probably benefit from some break-in. That is not in conflict with the fact that someone ran 20+ psi or 10s on a very fresh motor. But it might make more power after a break in. And it is also possible that you don't need any "special treatment" during the break-in -- any use might break it in.

i think the point here is that one of the most important factors in the longevity of an engine running high boost is the tuning. you were questioning specifically the 25 psi part, and i've heard others say that engines that make over X horsepower will not be able to last.
now i'm not speaking as an expert here, just my observations, and Kyle or Max or anyone feel free to correct me if i'm talking out of my ass here, but it seems that how well the car is tuned is more important than boost or output? engines can blow at 10 psi making <250 hp (like mine :mad: )
