more practice runs very soon..

Keep us posted! Fascinated thread btw.. I love all the doubters even though you have proof on paper for them to see!! lol.

Wow, small world, I think I've seen your daughter driving this car around town.
Judge Ito, do you work at a shop on Grand St in Paterson?

Yeah, I think I actually spoke to your other daughter. I work at autozone's commercial counter on lakeview ave, she walked in and gave me your business card.
I'm gonna need some PowerFC tuning done. PM me your rates/prices, and I'll give you a call after i get a base map set up.

Libor · 11-03-2011, 07:21 AM

Why so much skepticism? So many numbers floating around without any performance proof and no one is questioning their validity only because they´re in some ballpark what has been done.

Ito gave us dyno sheet and peformance proof, so what´s the problem?

I just put some numbers to turbo calculator, gave it very conservative IC efficiency, assumed 90% VE at peak power (I think this is pretty valid), conservative BSFC and AFR and it spit out 300 HP@crank at 9 psi boost. Torque values are also valid.

It seems that people are totally forgetting what makes power. I just happens that this very example is working efficiently despite all ods and doubts

Given the fact that Ito didn´t mentioned race weight, we can just guess. But at 3000 pounds, 300 HP would be totally valid.

Ito, could you share weight? Just to keep track with how the car performs

GoopyPerformance · 11-04-2011, 09:59 AM

Ito's HP and Time slips are totally legit... We sold his daughter a USED Rx8 PP right before their 12 second pass. I remember her rushing her dad to get going since she had a 6pm nail appointment.

Ito had a Rx3 called Little Josh running 9.30s on nitrous and a few other cars running low 9s more than 10 years ago..For whatever reason he took a few years off and now he is back tuning and building. He is totaly capable of a 12 second pass. And I am sure he can pull off a high 11s with the stock ECU and stock turbo.

However It seems some of the doubters are folks that are either new to Rotarys or not familiar with East coast performance scene.

RETed · 11-05-2011, 05:20 AM

The HP #'s coincide with the drag strip #'s.
That's not the problem.

The problem is the stock turbo / stock ECU / (basically) stock fuel system / stock (top-mount) intercooler / *STOCK TURBO* claim.
I was hoping more info was going to be revealed before it all went to crap.
There is no way the stock turbo can support airflow at the claimed ambient temperatures at the claimed boost levels.
Although we don't have an official compressor map of the Hitachi HT-18, we can deduce it's airflow potential by measuring it's compressor wheel inducer and exducer - nothing fancy with that, and it's a well-known method to gauge turbo potential when you don't have the compressor map in front of you - I've already mentioned this, but most have ignore that reply.
That's my beef.

My experience with a Hitachi HT-18 running around 8psi to 9psi of boost would produce anywhere from 200hp to 230hp at the wheels.
Judge Ito is claiming 50hp+ over that.
I find it highly suspect.
Nothing more.
I'm not insulting him, his shop, or his reputation, but I'm sure you will argue otherwise.
Plenty of groupies will just raise the "Hater" flag, but I've been through that before.
Now you come in here and insult us by saying we don't know what the "East coast performance scene" is?
I guess you guys are running some rarified air or using some magic pixie dust out there then...
But you're just going to tell me I don't know what I'm talking about and just blowing sh*t out of my ass, right...

JuanFelix · 11-05-2011, 08:33 AM

Pardon me if i may, I am fairly new at rotary performance but wouldn't the fact that the engine is ported which im sure was both intake and exhaust along side the larger injectors produce the extra power in question. is the principal not getting more air in and out of the engine as fast and burn it as efficiently as possible. I am very young compared to a lot of you guys and don't have nearly a quarter of the experience some of you have but i share that same passion that you do for rotaries. If the numbers are such and issue why not try your own build own setup like it and either confirm or debunk but i think its silly to keep taking stabs at one another in a irrelevant argument. i hope im not offending anyone i just want to move along and hope this forum does not turn into what the other ones have.

RETed · 11-05-2011, 09:17 AM

I'd like to know where the extra 20% to 25% gain in power came from myself?

Is it in the porting?
Does Judge Ito's porting make it that much superior that everything else out there?
That's what I want to know.

I doubt it's the porting.
Porting will only give you so much.
After a certain point, it's not the engine that's the restictions - it's the turbo.
Porting the engine all you want - bridge, PP, etc.
The turbo becomes the restriction.

It would be nice to get the answer to all of this, but I doubt that would be revealed anytime soon.
I'm not holding my breath...

listen you fucking hater, i've posted dyno runs showing the top mount intercooler. also posted a picture of the bone stock turbo. so shut the fuck up and stop deleting my post. yes it has everything to do with my porting and engine clearancing. nothing here to hide. it is what it is. and you continue to hate.

Judge Ito · 11-05-2011, 10:09 AM

to further avoid bumping heads with mods/admins from this site, i am done with this website. i have posted a video of the run at nopistons.com, if anybody wants/needs more info. on this car feel free to ask away over at nopistons.com where i am a moderator and have some home field advantage.

N.RotaryTech · 11-05-2011, 11:42 AM

Everyone just calm the fuck down.

Really, Judge, really!
I like the premise of your build, but you've got a bad attitude, and a drama-queen complex.

I have nothing better to say, so I'm done with this thread.

drama queen? if you only knew who you are talking too. far from that.. ted has been a hater for ages all over sites. this is nothing new. i repeat. for who ever is interested, updates will be at the other site..

RETed · 11-05-2011, 12:34 PM

You still bitching about this?

Do you even realize that (ZGN) restored the majority of the replies that I had initially deleted?
Now you're blaming me for all the other deletions - which I did not do?
Geezuschrist...
