793 HP Stroker Miata on M.net
 

I found this pretty interesting

804 PS = 793 HP

New BP record?

That's insane. I've heard of 600whp before. Hopefully the guy posts more details and pics of the setup. Wonder what transmission and rear end he's running. Definitely not a 5 speed and a torsen.

Ummm....


Did you notice the thread is from 2007? CEO also posted his build here when he did it two + years ago.

Also, I've got him beat through 5000rpms! :giggle:

Says rx7 FD3 tranny in the specs ;)

hey retard, how about resizing pictures??!!

i want more details about this. that's got to be one insane slingshot feel.

Did you notice that he bumped his own thread TODAY with a dyno sheet?

The forum automatically re-sizes pictures....

Guys CEO is Greek too. He is running a Quaife Transmission Cusco differential and racing fuel.

His car is a beast after his final modifications, and he is planning to install an 9'' differential.

After all the cops over here are pretty lazy and they don't care much about street races.So we are lucky.

Believe me the dyno is 100% true.

exactly, the thread is old but the dyno numbers are new.

Up until this the highest output BP I was aware of was 616hp, so if these numbers are accurate and he is really putting out 793hp, it is a very big achievement.

thats crazy!! take that fe3! i want that set up in festiva it would be such a sleeper!!

Do you know how much boost? The 3540R turbo he talks about is a Garrett GT3582R. They come in some big A/R sizes in the T4 frame (up to a 1.06 A/R, IIRC) but 800whp is still kind of high for that turbo.

Sav, he posted: "in 30 psi with VP Q16 fuel" on the m.net thread.

The stroker is taking 30 psi to 8700rpms, seems to be really bulletproof.

How the hell does he find traction on R888´s, I don´t know.

From 5k to 6.5k that think must be a fucking rocket. I bet that thing is pointless with no traction at all

If I lived somewhere that type of power/speed was "accepted" on the streets, I'd be dead. That's an insane amount of power out of that motor.

At first I thought it would not be very driveable when I saw how late the turbo hit full boost. But, then I saw the redline; The 8700 rpm redline gives the engine about 2200 RPM range of fairly flat peak power. Hell call it a 3300 RPM wide powerband of insane 400+ horsepower. Not much worse powerband width overall than any other turbo bigger than say a 2871. With that steep torque curve that thing must hit like a freight train. In a word, awesome.

What's up with torque and HP crossing at 7500 rpms? Maybe I'm in idiot for asking but I thought that was consistent at 5200.

The dyno plot won't load on my slow ass phone connection, but I'd guess it's because they measure horsepower in different units over there. Still a function of torque, but a different equation.

So does how much power would this thing be throwing down on a dyno here if that's the case??

Holy balls, that must be a wild ride after 5500 rpm lol.

awesome torque curve.

not only are HP and TQ not to scale, they are measured in different units. Math fail.

~30KgM @ 5252rpm = ~216ft.lbs
~225PS @ 5252rpm = ~220bhp

lol, I'm bored as shit this morning so I am going to put my 320/305 chart and his 793/550 chart onto the same graph in excel.

Big cylinder head, big camshafts.

I wanna see what he did to this head to make it flow well at nearly 9000 rpm. Aren't these heads notorious for dying out at high rpm?

There is a reason alright, nobody uses a big camshaft. The miata head flows better than some NASCAR heads. He was man enough to get the combination right and not use a pussy cam.

Are you on crack

The BP does not have a good flowing head, It is extremely naive to think it is compared to many modern engines. The BP is fundamentally designed to be a torquey turbocharged engine, the rod ratio alone shows how the engine was never intended for high rpm use. You wanna see a good example of a production high flowing naturally aspirated head go look at a honda F22C, now thats a head that flows.

NASCAR engines are capable of 200+psi BMEP, the fact that you think the heads are even comparable is laughable

Still a 2 valve head. Considering the bp's bore size, it is pretty damn good. I have seen flow numbers from developed BP heads out flow some of the Nascar heads that are a few years old.

I did not compare it to a stock four valve Honda head. We are not using Honda engines, we are using bp engines.

My comments are to encourage motor development, which is sorely needed around here. Do you suggest that we just live with the limitations of the bp, or go and fix them. :facepalm:

I'd love to see a few links to threads which indicate a "sore need" for engine development.

Maybe he wants us to all run carbs, too. :dunno:

wait omg i thot carbz were bettr?

My observations: The overall approach of the builds at this site, with some exceptions, is about getting the most power for the money.

The Miata crank is bulletproof, the block is strong, the block to head interface is stout, good rods and pistons are readily available, there are several good options for exhaust manifolds, and the exhaust itself is well sorted. Lots have developed solutions for the intake, from gutting the stock manifold to a full custom unit. ECUs are also taken care of, several flavors to choose from.

So that pretty much just leaves the head. Oversize valves are already available. Springs are already available. VVT is being experimented with. Static cam timing tuning has been done. So that pretty much leaves porting and cam profiles. Head porting and the like are nice, but from what I have seen they are pretty expensive to get done professionally and/or properly. I have seen some play with cams but not many.

Clearly the builder in the linked thread spent an insane amount of money on his motor, and is not running pump gas. I think it is well beyond what most want to do here. For insane power levels, a V8 swap is overall a cheaper and more bulletproof option if one is trying to get above 300-400 RWHP.

So in my mind the above explain why no one is sinking large amounts of cash into head work and/or cam profile experimentation. It is easier and cheaper to build a stout motor and turn up the boost.

This miata2slow guy is quite amusing!!

Unfortunetaly this engine wasn't that bulletproof. Rumors say that the engine exploded during performance measurings a week ago.

Man, if I sunk that much money into a motor and blew it up...
:vash::vash::vash::vash::vash::vash::vash::vash:

My guess is "that much money" means a lot less to him than to most of the forum.

Cliffs: Most of us are either too poor or not interested in spending $25k in upgrades to our $2-10k cars. Most of us are not street racing from 50 to 150mph in a straight line in our cars and can't effectively use a car tailor built for that purpose to do what we are doing. But we like and admire the ability of others to build such wonderful and capable toys.

for sure bro my dad's friend has a car w carbs runnin FIVE HUNNURRRRD HURSEPOWER runs 7s in the quarter fo real
