What I have done which really helps is open up the wastegate completely (un attached the wastegate actuator) and I don't have problems and only get boost at 6000 rpm

Detonation resistance increases with RPM. Now, your motor desperately needs more fuel. 8psi should be something like 170whp, you are probably making all of 100whp, or less.

I'm thinking this guy is a total troll at this point.

Where are you located? I'll have a 91 1.6L for sale soon.
Also whoever gave this poor guy -1 on every post is a dick. so I fixed it.

I've got a 1.6l sitting in my storage room too.

Sorry, posted wrong place :vash:

I am really not trolling, i was hoping that the meth would make up for the lack of fuel, and i have reason to believe that.

On my mazdaspeed when you hit about 325-350whp you start to have fuel problems, the crank driven fuel pump cannot keep up and your fuel pressure drop from the ideal 1900 psi till 0 where your engine goes kaboom. Now i was going to buy anew fuel pump but my friend had a Stage 3 methanol injection kit that he said i should give a try to see if it would remedy my problem. So an hour later with the kit installed we take it out for a spin and Bam! no more fuel problems! It also made my car scary fast (its like adding boost to boost) I was running PIG PIG rich (in the 9-10 range) I was hoping the same effect would happen with the miata.

I guess not, going to do a compression test tomorrow and i will let you know if i will be getting a new engine or not (P.S. i live in Canada)

Lol @ adding boost to boost!
Your miata was not factory boosted, so the stock computer will not add fuel in boost. Your fuel pressure won't increase, and meth has nothing to do with adding fuel.
You need to find a way to make your car add fuel when it goes into boost, it's the simple.

Wow. Trollmastahhhhh

I wonder how often you have to replace the fuel pump belt? Shiz gets real when that thing breaks from pulling 10,000rpms! Who would've thought they would move the electric fuel pump from the gas tank?

2. Hope you didn't kill your motor.

5. sell car

4. buy civic

My Opel Olympia -56 has a crank driven fuel pump. So does old Volvos and I am sure more. I am also sure this dude is a troll, however trolling quite well.

If I am wrong, we have once again proof that the Miata engine is a strong little bugger. 2months of 8psi with no extra fuel and still running? Respect.

soviet 02-08-2012 11:56 AM

1) mazdaspeed3 have direct injection. hence 1900psi fuel pressure.
2) they also have camshaft driven fuel pump
http://edgeautosport.com/products/CP...3-HPFpump.html

The high-pressure fuel pump used on the Mazda vehicles is mechanically coupled to your camshaft
lol @ complicated new cars

edit: to clarify, the high pressure fuel pump is in addition to a regular, submerged in-tank low pressure fuel pump. yes, two ****ing pumps

drummersrs 02-08-2012 12:03 PM

stop this nonsense and get engine management.

Running a 9 or 10 afr will wash the cylinder walls clean of oil, if it would even run. At that point the oil pan will be soo full of fuel that you would have to stop trollin.

So the miata received a bit of love today and the engine really is a strong mother F*****

Compression test put out a nice 210 - 225 - 200 - 210

Got new Plugs and she is back to purring like a little kitten.

I will be getting some sort of engine management either way, or maybe trying putting gas into the meth injection kit hmmmmmmm...

soviet 02-08-2012 03:46 PM
