See now you're talking out your ***. You clearly said something that is not true. Which is that your big *** 30r turbo is spooled by 4k on a 1.6L.

You did NOT correct that statement or interpret it to us for days. Now you come back in and say "that's not what I meant. I mean its good spool, not full spool"
Can you be any more vague?

A 40r car can also say "I have good spool at 4k". It is nowhere near peak pressure but that doesn't matter right?


Oh well, I knew it was too good to be true. Good thing I didn't hold my breath.

Don't get me wrong, you have a cool setup. Just need to be more specific when you STATE something.

 

why guys you are too offensive here ? i haven't any reason to tell lies i know my car and i am serius tuning it. No diy manifolds, ecu's and engine builds. I have seen too many 1.6 engines push easily a gt3071 not only the Mazda bp 1.6.

 

We're not offensive at all

When you say something like what you did people get excited. Because its either unheard of, rare, or a very big achievement. So they expect for you to deliver the proof.

And don't compare a miata 1.6 to other 1.6L's. Not the same.

And we're not flaming you. More like disappointed

 

I mean it in the sense that I opened the thread hoping that you had numbers and spool data already. Is true what 18 said, or at least I agree with him. Im anxious to see the result. Dont take everything that is said too serious

 

this is my first post about spool in this thread.
Where i said about full boost man ? I am not crazy i just sharing opinions to a very usefull forum for me.

The only thing that i can do is to post my dyno and some videos of my car.

I can't believe that a fiat punto 1.6 8v (1993 design) can beat our engines.
I have too many examples for you.Maybe smaller displacements are not too popular to you but believe me are too strong.

ps : 3071 is much quicker to spool than 2876

 

Why does your NB have a 1.6?

 

Maybe becouse i am from Greece.

 

Oh I see

well is it a normal B6?
I thought the 1.6 in theeuropean NB's was different and made more power, but maybe Im wrong

 

So where are the videos??

 

George they have 1.6 engines there too. The most na's are 1.6 .

I can see a point to 18psi's talking, but he missed the picture of this thread and he insisted for something you never said.
Anyway the 30r sure is a big turbo for the 1.6 but who cares?
In the track or in a street race the 30r will never leave you without spool changing at 7k rpm.

 

is normally 110hp. bp4w is the code i think

Buffon01 when i finish with my car i will post some videos. I haven't with my previous setup.

 

Watch out, most of the Miata community is suffering from small turbo syndrome.

 

There is a reason about it and here in Greece we call it tranny failures.

 

There is a solution and here in America we call it a 6 speed

 

But of course, 6speeds for your small turbo syndrome is just all you need.

 

The ones with the 6 speeds tend to get turbo's on the bigger side

 

come on guys. Problems are worldwide. But is true that an 6 speed is more expensive and not to stable solution like an rx7 II . Don't forget that you need to change and pinion ring to 3.6 if you go for the 6 speed.

 

I'm just giving him a hard time

You have a very nice setup BTW.

 

Come on George can't we have some fun here?

Seriously I haven't seen a 6speed failure but if I had chose the 6speed path and meet a failure then I would propably cry my money. Couldnt take such a big risk.

 

That turbo looks huge in the engine bay, almost as huge as that radiator. I like 18psi was hopeful you would have hard data about spooling larger turbos. I'm also running a 1.6, but with a t28 clone. I'd be stoked to find out i could run something larger and have potential to flow over 300whp with out having to do a 1.8 swap.

BTW I always thought the European 1.6 that was available at the same time as the 1.8 made less hp than the original 1.6 from the NA6 miata's. I've seen articles that refereed to it as detuned. Sort of like the 900cc motor in the Honda 919, vs, the CBR 900.

Have you seen any benefit from that torque damper?
