Vince...

I'm not sure what you accomplish with running the Dynojet Winpep software yourself. The end is a line graph, just like you would get if you attended a dyno pull outing a dealer puts on. I have several files of data comparing one motorcycle with another; great for me to play with, but not any more useful than a before / after printout as Chuck has provided. Your challenge to "simply provide raw data" will not uncover any tricks that a dyno operator might try like, no fan on the intake, air con turned/off, Traction control on/off, etc.

We don't own a dynojet. The dyno was performed at another independent dyno shop and I am not sure if they will be able to provide me with raw data. Be honest with you, I have no idea how to operate a dynojet or manipulate with raw data.

Chuck Huang

 

Then you can disregard the information that you don't want and be on your way. Easy.

Vince

 

So your claims go to the bullshit pile. Don't worry you have plenty of company. Can't say you didn't try!

Vince

 

What's your problem? Becuase I don't own a dynojet and I don't have the raw data on hand and that makes my dynosheet a fake and bull ****? The dyno place is 2 hours away so once you request, I have to drive down there to get it for you? If I spend time to get it for you so you can play it on your computer, will you purchase one?

Best of all, you can purcahse one and dyno it yourself and see what it does before you call bull **** on anyone.

You seem very negative and I don' t understand where that's coming from.

Chuck Huang

 

I agree with Chuck. Too many people here cry bs and yet half of them have never even seen much less know personally how a dyno works. I'm sure if anyone purchases an intake, dynos the car, and proves that there was no gain whatsoever, Chuck will be willing to let you return it. Of course if you do dyno it, you'd better own the dyno yourself, and know every little in and out on the details of it! After all that would only be fair wouldn't it?

 

Chuck,

I agree with you about the dynos. but anyway..

Could you comment about the driveability of the car after the intake is purchased. There has been a lot of discussion about the Borla exhaust install (which I have) and have noticed that the car isnt choppy at all down low and it merely just increased the power.

I am really curious about the level of performance after this mod has taken place. With the Borla the power really felt a lot better after 5.5 on up and I am curious what you felt after riding the car. That to me is the best part. Hearing what your personal experience with the power has been.

It gets people talking I think.

Thankx a lot!

 

After the intake is intalled, the car's drivability is the same as stock. My butt is not as sensitive as before because my project rx7 has a lot more power than the RX-8. My rx7 on pump gas has about 450 rwhp and every additional psi of boost gives the car another 25 rwhp. My butt dyno is probably the least accurate one. :D That's why I had the rx8 dyno tested.

If you look at the dynosheet, you can see the HP gain increases as rpm goes up. This makes sense since engine at higher rpm requires more air and the less restrictive intake system will make more power at higher rpm compared to a more restrictive intake.

To prove my point, you can do the following test. Dyno the car with the stock air box and then dyno the car again with the stock air box but no air filter. If there is not any HP difference, you can say a less restritive intake will not make any hp gain and any kind of aftermarket intake should not provide any noticeable HP gain.

Today, I talked to another shop who told me that they did the above test. Their car's base line is 185 rwhp and after they remove the filter, the car has 197 rwhp.

People who have doubt are more than welcome to perform this simple dyno test. It's a lot eaiser than swapping intake system on the dyno. You can remove the filter out of the air box in 5 min.

davefzr...
A simple 'home dyno used to quickly verify changes is to locate a nice spot on a straight road. Always use this same section. Up a hill or flat is fine. Start a timer at a start spot as you hit the gas in say 4th gear at a predetermined (again always the speed), 20 mph or whatever works for you. Measure the time it takes to get to either a certain rpm or a certain mph, no shifting. Do three runs and average. Make your change to the car and retest. Will not tell HP, will not even be that accurate, but it will record significant differences and is better than just "feels like more power".
Tom

 

Chuck,

Your the one making a very large profit from your HP claims.

So far you have made most every bullshit excuse (I'm waiting for "the computer crashed" or "the floppy drive doesn't work") for not producing the data.

Go get the raw data from your Dynojet people and post the raw data from all of your dyno runs.

Again, your the one selling 35.00 worth of parts for 300.00 and making bold HP claims. What I'm asking for is very simple, show us the raw data please.

Vince

 

Guys, this is getting ugly. If you wish to continue the conversation in pms, go ahead, but take it off the public forums. Thanks.

 

Elara please do not close the thread. It seems that there is only one person here who is creating very negative comments. So far Chuck has been answering every question in a very proffesional mannar, and I have certainly learnt a thing or too. I am sure that other posters will back me up on this one.

I agree though, if your going to give someone ahard time...do it through PM's

 

Wasn't planning on closing it. Just don't want to see the nastiness that's being thrown at Mr. Huang any more. As long as it stops, the thread's fine.

And while I apologize for stepping in here, enough people are complaining the mods do nothing about flaming that I'm going to crack down hard on anything resembling personal attacks that I see from now on.

 

1. The filter itself already costs more than $35. I don't know how you can make the exact set up for $35 including all the components and features.

2. You can spend the money and do the testing yourself. You will be happier that way. No matter what kind of data I provide, to you it's all bull ****.

Chuck Huang

 

I don't mind all the quetions and I am happy to answer them all. Thank you for not closing the thread for just one person being extremely rude without any kind of internet etiquette.

Chuck Huang

 

I think that if you use a forum to sell your goods and someone asks questions you need to answer them (and not duck and dodge).
The bold HP claims were made here and my questions should be answered here.
I take it personal when someone tries to gain my trust then lie to me and make a fat profit.
Mr Huang,
Lets get this back on track and show us all the data from your test dyno runs.

Vince

 

What question that people asked I duck and dodge?

Go back to my post and read what time I posted about the raw data. When I saw your post, it was 7:30 pm and the dyno shop was already closed and that's why I said I am not sure if I can get the raw data or not because I couldn't reach any people at the dynoshop at that time. The earliest I can find out if I can get the raw data will be on Monday when they open. All the other questions have been answered.

If you can get it done for $35, it will seem like I am making a huge profit but apparently I can't get it done as cheaply as you can, not even close. I don't know how it's possible. I am sorry to disappoint you. I am not making a huge profit. Can you show everyone how you can get it done for $35? They will love to hear about it as I would too. Can you not duck and dodge this question? Can I call you bull **** if you can't back up your claim?

Chuck Huang

 

Thanks Chuck. We await the data.

Vince

 

Who's "we." Vince, you clearly are of the opinion that its all BS and anything that doesn't exactly match your requests will be used as evidence of that (the title of the thread you referenced is evidence enough of that). If he manipulated the dyno chart then he could manipulate the raw data just as easily. I really think he's done what he needs to do here. Obviously, if his intention is to lie about his intake performance, he can do so with any data he provides. The truth will come out, either way, when someone buys his intake and tests it themselves. Really, you're welcome to your opinions and all...but he has provided data. If you want to call BS on it then the onus is on you to prove that data false, whether its a chart, a table of numbers, whatever.

jds

 

I still don't understand Vince's hostility towards aftermarket vendors here in the forum. If anything, we should be thanking these people for developing products for our car, but instead they face the endless and unfair scrutiny from some of the members here. So far, the only person Vince trusts here is Canzoomer who hasn't posted any evidence (dynos, raw data, etc.) on his claim. I have nothing against Canzoomer, and in fact, I would be the first one in line when his product becomes available. Maybe Vince is waiting for Chuck to send him a free intake so he can test it on his own that's why he's hounding on Chuck. For what it's worth, I think Chuck is doing a good job of answering all the questions so far.

 

...and Chuck has stated he will refund the money if not happy.

 

Hostile, hounding and unfair scrutiny?

When someone tries to sell you and me something based on lies and bullshit you should direct your suspicion to them not me.

The truth is a funny thing sometimes.. You should demand some for yourself.

Vince

 

How about lets expose it for a fraud and not buy it first and save some people from getting ripped off?

I mean "We" as a group not as a whole.

Vince

 

I'me sorry Vince, but I tend to beleive well established companies that produce this sorta thing. When the person responsable gives me a money back warranty as well, I feel comfortable that it will perform. I dont know why your so hell bent stating this is BS, when as far as I know, you have not shown WHY it's BS other than your opinion. I also dont know you and have no idea where your experience comes from, while RE has a good reputation with RX-7 owners I have talked to.

YOU dont have to buy squat from this man if you dont want to. But your ragging on a guy who has not shown any reson for that sort of behaviour. He has been open, honest and helpful about this intake. Your wanting raw data is pointless as if he was smart enough to modify the data to show his numbers, it wont show up anywhere if your just running it through the vieweing software.

Your only way to prove it's BS is to put one on and try it out. NO other electronic form will prove anything otherwise. And if ya dont belive me, I'll get the raw data for my dyno run and show you data that says my car has 7000HP.

Please, be fair at least before being offensive and possibly scaring new people off who dont know whats going on.

Or ignore me altogether. Whatever floats yer boat.

 

Once again, what is your basis for calling their claims lies and bullshit when you haven't tested yourself or anyone else for that matter? All I'm saying is let's give these people the benefit of the doubt until proven wrong.
