I really would love for this to be true but that's gotta be a record or something. Are you using those light weight billet rotors? What's the secret? cause you have no shame claiming those numbers like it's nothing. Please make us believe this.

 

ha you know you're gonna give me a ride it that beast!

 

So you somehow managed to get the turbo to flow more then it physically can? 87 lbs/min = ~870 piston rwhp / 1.3 = ~669 rotary rwhp max assuming ideal conditions? Forum dyno numbers make me lol every time. Aside from that, its probably a fast car with that turbo.

I always wondered why these high HP dyno's are never by RPM. HP is a calculation of torque and RPM, if RPM is not known, how exactly is the HP being calculated o.O



thewird

 

The 4202 flows 87lbs of air/min, but at what boost? The flow chart is when the turbo is flowing at its best. It doesn't mean you can't push the turbo beyond. Not saying this dyno is true or not, but pointing this out to ya.

 

More reasons you can't just go by a flow chart....
You don't know what kind of timing he's running
An aftermarket UIM can yeild as much as 50rwhp
Different porting can yield as much as 100rwhp (ie..Semi PP, bridge, etc..)
And simple things such as his exhaust system will yield more power.

 

Bring that to the japtrix dyno and we will check it out to see if this is real i would believe it if it was a 3 rotor motor but not a 13b and not at 20 lbs i would have to go with the rest of the guys and give this the thumbs down.

 

A better known more accepted dyno would be a dynojet. That way you could do SAE, corrected, std...

 

for sure
yeah he pulled a bike on me before i let off.

oh and heres the dyno vid sorry correction it was 23lbs and not 20lbs

At just 20psi, even in ideal conditions, it would be saying it making what, 300@wheels n/a? From a street ported 13B?

Im not going to cry BS as you can never say never, but im interested, thats for sure.

 

That theory isn't sound.....

 

Damn what porting is done to the motor it boost and rev so quick? Can you pm me your pictures of the porting?

 

Whatever you got in that car..... i will take two of everything. Lol

 

I don´t believe that rotary needs 30% more airflow for same power. More yes, but not more than 17%. I assuming it based on BSFC of rotary vs. 4-stroke at given AFR. Also on torque values of all out racing N/A rotaries vs. 4-strokes


On the main note anyone remember this? https://www.rx7club.com/showthread.p...hlight=700+e85

 

Sounds like there's no load on the dyno. 4th gear rev just as fast as first.

 

ok isnt there suppose to be a load on the dynamic? That thing sounded like it wrapped up really quick.

edit-^beat me to it.

 

IIRC, in another thread/video he credited the UIM with the quick throttle response.

 

Thats because hes in steady state mode and only a speed restriction
You need to do a ramp run but if having traction problems use a faster acceleration rate.
Rx72c needed another 11psi boost to make less horsepower something sounds dodgy

 

is it that car that ran 4x1600 injectors and made 699rwhp?

Im on a similar setup and will be tuning my engine on a superflow engine dyno in a couple of weeks... will be interesting to see!

have fun and take it easy on the roads

 

Well if the bike jumped on you and only had half a length on you then your car should pull some good traps.

Yea thats some pretty quick revvin through the gears on the dyno there... I think you should take it to another dyno just to see the difference between the 2 dynos.

 

My .02 cents

1. I think on April 1st all this is gonna come to light..... APRIL FOOLS......... lol.

2. Or the secret is gonna be billet rotors.. Some of the videos of the als fd have me thinking that they might have snuck some of these rotors in and showing what they can do..

3. In his video, you can watch other videos after his stops. Well there is a vid of a red drag car, think it also says als car somewhere, and it did similiar hp numbers. So maybe they are laughing at us who are trying to figure out the secrets..

 

At 20 PSi is where I took the number from. Efficiency drops off fast going beyond the chart and I don't believe he is going off the chart with a street port regardless of his special LIM.

23 psi is a little more believable. Turbo flows 91 lbs/min which is 700 max rotary rwhp

Think this is a classic case of dyno reads high, owner is happy. Regardless, its just a number, the car is probably a rocket.

thewird

 

23psi and 737rwhp?

Thats bloody huge power.

I dont know if my eyes are playing tricks on me but i could see roughly 1.5 on ATMC correction.
Its the green field which tells you how much the dyno is correcting the power figure.

Congratulations mate. Thats a bloody well done and a half.

 

That's some sick response. I look forward to some more vids.

 

the Underground Gallardo is fast,, right down the street from me , same guy with the 6speed supra, at 246 st. mile, he got some of the fastest cars in USA.

course im jealouse

 

thewird. This is why i ran the bike to see if my horsepower figures were right. If they weren't i would of gotten beaten pretty bad.

yeah 699rwhp @21lbs of boost. is making like 770hp now @ boost unknown

you will when i get my boost controller & up it to 30lbs ahhhhhhhhhhhhhhhhh


Besides me whoelse has that 4 barrell throttlebody?????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????
