I have not seen many pics of peoples hard work and dollars spent on their turboed/ supercharged beasties! Or even just your favourite engine bay that makes you dribble!

Every proud owner out there please post some pics!

I will start.

Were you influenced by dr seuss in any way in your construction?

And mine, great to see so many different set-ups.

And my CAI trial.... FAIL.... soooo noisy. I know there is no benefit while having an I/C but I just wanted to try.

Then perhaps that should be "Lyin Miata"

The inset white letters look great. So who's is the blue motor?

Habanero666 · Post by **Habanero666** » Tue Sep 08, 2009 9:16 pm

Magnamax I think, and yes it makes me dribble.... so much I am gonna build this spec engine!

I am not lyin man I just chose the engine bays that make me dibble because I have over posted the 1.6!!

He's still not happy,wanted 300whp,didn't like 600hp Skline GTR's beating him

Oh dear, I would have thought that was easily obtainable! might need to go the- 1.8 with big cams and the tdo5h 16g turbo way!

Always depends on how big your wallet is Depending on how much power you get,I think he told me spent near enough to 10k to get that far,Most of it is high end stuff and hand built ,Custom pistons/Turbo Computer etc etc.
You know the usual story,What you think your car makes and actually having to spend a couple of hundred to find out on the Dyno for real what it does make is a different story.
Many motors have melted down finding out.
The other thing to remember ,his car IS 280WHP AND just 600kg all up ,So what would the power to weight ratio be ??.
Who out there is clever enough to work that out?

Habanero666 · Post by **Habanero666** » Sun Sep 27, 2009 10:33 pm

Hmm I would work out power to weight to be 0.4666:1 , not bad at all, nope very impressive indeed.

Anyway then there is the issue of traction...... the skyline may have 600hp but they are usually weighty Behemoths so that would leave traction as the hidden factor here, you could have asked Peter Brock but.....

I see you can win a dyno power run on trade me for 115 NZD but it is in Foxton, not far from Palmy North.

I agree, you can hear some "side splittingly funny" predictions of power, but we all have to bare in mind that an unbuilt bottom end will only handle 250hp SAE (at the flywheel), so a well prep'ed one will be safe up to 320hp within a fart in the pool, and then you can have the concrete filled block with billet main bearing caps with yada yada yada $ $ $ so yep anything is possible

Interesting, is that an NA or NB? I recall reading the NB had a bigger crank and possibly rods, thus I was assuming much stronger. Am I on the right path? Also if you are getting say 200RWHP what would be likely to be seeing at the flywheel?

What would most likley fail if you push the power too far (assuming motor tune was good)?

Another thing worthy of adding to the mix is to consider if it's power in the right place. Like the 500HP MX5 discussed on the forum recently, nothing at all down low and then a huge kick in the pants. So power isn't everything, torque at 3k rpm is probably more useful for most people like a T25 setup, but if you are on the track then I’d guess tons of power at 6k rpm be the winning ticket. Thoughts my peers?

The 1.6 had a superseded big nose crank after mid 1991 from 22mm up to 27 to address the associated issues with breakage. The Rods are the same length for the B6 and Bp 133mm.The BP crank is longer shares the same bearings and the mazda GTR crank is forged steel.

I personally have gone with shot peened B6T conrods from a '89 323 turbo which weigh 580gms a piece and has stronger fastners, compared to 540gms for the standard twizzle stick conrods that are the replacement part from Mazda, and are in all but the swapped out custom engines. Th e Picture below will show you what I mean.( hopefully I won't get assassinated for letting that secret out?)

I believe the BP is a stretched version of the B6 to allow for a bigger bore diameter.

I will receive a bit of flak for this but here goes,
You will probably have 225-230 Hp at the flywheel if you put 200hp to the wheels (but all engine, clutch, transmission combos will yield different results give or take 5 hp).
If you consider that losses attriuted to friction=heat energy loss as the governing factor of power loss pull a thermometer out of yo butt and pop it in the tranny fluid when you are spinning the vehicle up on the dyno...and see the rise in temperature .Mechanical losses are not huge.
Besides the these mechanical losses are non linear and can not account for the massive corrections I have seen spat out of someones $$ making dyno skam calculators! " Oh you have to get this done or that done if you want this power " type scene.

I have heard of a power quoted 450whp 4wd familia from a number of trusted witnesses and can attest to seeing this thing doing Helicopter burnouts! in front of a few hundred gob smacked people.

Max power on a standard B6 block with very precise tuning: global answer= 250hp at flywheel anything more is walking a thin line( to quote too many people). The BP I have been told by a breathing living tuner, will handle up to 280 flywheel Hp and again with careful tuning.

The difference in terms of tuning advantage would be the increased torque, potential for top end power and better engine airflow of the 1.8 also the fact that there are alot more AEM parts to get things hotted!

The choice is yours and the wifes in most cases!

yeah, what Habanero666 said...

the rods generally let go first, more so in NB's. Even tho the dimensions and pretty much everything look the same as an NA conrod they're weaker... the latest favourite rumour was different metallurgy.

way back in the day, they actually threw a B6 (?) engine on an engine dyno (its in one of the early Miata Magazines) and measured the drivetrain losses at 26hp at redline, so this seems a reasonable number to add on to whatever rear-wheel hp figure you have .

hey poison - what does that g-meter thingy tell you ? It can do hp estimates, right .. :]

Here's what Ray Ayala (MiataLink software writer) said about knock and dead engines:

It does show up in datalogs as a noise small enough to be confused with valve train noise, except that it's envelope is rather impulsive in shape while valve train noise is more continuous. In a stock-CR M2 motor it usually starts to show up around 5-8 psi (depending on ign adv) with west coast fuel and can be destructive in a very short time.

Silent knock - as in knock that the knock sensor can't detect and make
up for? Or something else?

I wasn't aware that knock was a serious problem running Premium and only
5psi boost.

Hey jif
Yup I have a g-tech pro. You program in the car weight and it does hp
over a 0-100k run. You can upload to a pc You're welcome to borrow
it. Call me. My iPhone has a similar software package, I must
compare them sometime.

So,280 rwhp off a B6T in a 600kg car is not bad eh

.
That a every day driver (JUST),He admits traction is a bit of a issue,Or lack thereof.

Yeah! Hahaha, I would imagine the turbo lag would be a killer!

I also wonder what intercooler is used?
