well done

 

Great figures brg, looking forward to getting some of mine own!

 

can you tell me what kind of internal mods you have supporting that?

 

he ran that on a stock motor and it eventually blew up

 

..but to caveat akaryerye, didn't he blow it up @ 17 psi?

not to knock bubba, but @ 12 posts it's likely he doesn't realise how much boost a Miata engine can take with stock internals. Hell, I've had people ask me if I was going to get my engine "sleeved" before turning up the wick :gay:

 

it only blew up (bad rings) when he went to megasquirt and starting running more boost. he ran it in that configuration for a few years with various track days.

 

Wow, more boost than 15psi on that turbo?! That seems a bit crazy.

 

Yup, can handled 15psi for a little over a year including a few pretty strenuous track days.

Engine gave up the ghost at 18psi. I was NOT trying to run the engine at 18psi, but my crappy Autometer boost gauge was reading 10-12 psi so didn't realize I was at 18psi until after the damage was pretty much done.

 

That sucks. Did you rebuild and get it back up and running or just go to a new engine?

 

see his sig silly. :gay:

 

My visual acuity is low apparently. Need to...

 

Curious - what A/F ratio you seeing at peak power in that graph ? Better yet what target did you tune for ?

 

Pretty much dead flat between 12-12.5 AFR which is right where I was aiming. I think there might be a pic in one of the old threads. It's the beauty of olderguy's autotune.

 

are you running an intercooler or just crossover? i know this thread is old but i'm debating intercooler or not

 

wtf? you fail to forget the greddy turbo is one of those magical non-heating ones.

 

i know that stock greddy's came with crossover tube so i was just asking, magnamx-5 has no intercooler and i didn't see any other info about his setup on this thread or others

 

richard runs water injection. click the vbgarage and see tom's setup in full.

 

Scot you kill me yeah Mazda nissan he runs a big ole FMIC

 

Sorry I didn't reply earlier, I used a big FMIC b/c my AC is removed. It's the one one ebay with 2/5" in/outs and IIRC the core dimensions are 12"x9"3". It's a little on the big side IMHO, but it was cheap.
