racing beat has a header coming ou tthis spring and the guy there said they were making 7 to 8 whp from it and try to price it from the 500 range

ddub

And it will weigh 10 lbs more than the stock exhaust manifold, and actually provide no gains. Racing Beat is bad news, stay away

toca

oh i forgot to post this and racing beat is going after carb with there header too

ddub

Also, either you're confused, or racing beat is lying as usual. You will not get 7-8whp from a header on the rx8, they can't even do that on the n/a rx7's where it provides more real gains from free-flowing header.

toca

just telling u what racing beat said damn dont get all up tight about it lol

RB themselves have stated, on many occasions, that even with NO cat and NO mufflers, there was only a 2-3hp gain..... so 8 from a header? dream on.

ddub

Since when did Racing Beat say this, though?

As far as I know they haven't said anything like 7-8whp, unless this is new? On the site they say " 2. Headers – approximately 4 HP peak power gain."

toca

they said this over the phone 2 day ago.

ddub

Well they lied to you, get used to it with racing beat.

ddub

No... No header will with STOCK port and STOCK exhaust sleeves/inserts. The exhaust port runners/sleeves will not flow enough to make many gains on any aftermarket header/exhaust manifold. With the OBX I'm hoping for like 2rwhp at most, and I'm going to doubt that. I wouldn't expect more than 3rwhp from any header produced using the stock engine ports.

Also, never trust when a manufacturer dynos their product themselves. What are they going to say, they lost power? Or that they got the same results as every other product? Of course not, they are going to make it sound as good as possible. Just like the original K&N intake where they claimed 9.5hp or whatever. When independent people dyno'd it themselves, they lost power. So until someone dynos that exhaust without being bias, you probably shouldn't believe it.

Who is TurboXS?...oh, that's right, the guys who are trying to sell it to you told you TWENTY-ONE HORSEPOWER.

Not twenty, I like that touch, makes it SO much more "believable".
(Damn, I lost that "eyes rolling" emoticon again!)

um why dont u take a look of there dyno sheets they have on here and its not turbpxs own car they dyno a members car on here and got those numbers

ddub

So? Dyno's are not that hard to manipulate depending on the conditions, whether or not BOTH runs were SAE corrected, etc.

army_rx8

^good point..i'd believe a third party dyno numbers...not a company..regardless of who's car they are dynoing....thrid part impartial is the way to go in my honest opinon

It's funny how someone can actually insult the single most experienced and honest rotary shop in the country. I guess it all has to do with the fact that they don't claim to be the be all end all when it comes to power and are more down to earth with gains. Anyone who doubts them needs to go see their setup in person. Your doubts will be gone.

On the topic of the header I will say that their original claim that headers could only get 4-5 hp but now they are saying that they are getting 7-8 hp, isn't hard to believe. Think about it. To say that 4-5 hp is the max possible assumes that they tried every single header design possible. I do know that they tried literally dozens and dozens of different designs. All that means is up to that point anything they tried only got a max of 4-5 hp. It is possible that they tried something after that posted claim that actually did get more power. Edison tried nearly 800 lightbulb combination before he got one to work. If he published a claim before this point that the lightbulb wasn't possible, this assumes he tried it all when he hadn't. See how this can all be possible? That's the beauty of not giving up when you fail.

said so wonderfully

toca

ya the guy at racing beat told me same thing they said a frist they had a hard time but a came a cross a new design and it worked and there getting 7 to 8whp i forgot to ask them tq numbers but this is why there going to release it is because they said they finally got a design that worked

Seems that there is an alternative band wagon passing through town with "I hate RB" written on the side. To equate RB with K$N is really a streatch. But to each is own...

So, I was already to send my obx header to get the jet hot rotary treatment, when my mechanic brother-in-law (who is a great guy) said that he would be willing to try and bung my header (ha! "bung my header"!)with a port for the air pump. All he has is welding equipment. Is this going to happen? Also, do I really really care? It is not like it is going to make me fail emissions in MD, right?

Was their first claim of 4-5whp gained from headers made before they released the Revi and Ram duct?
I am curious to know if Racing Beat tested the headers with the stock intake setup which produced only the minimum amount of gains or did they test it with their aftermarket setup?
Or are they leaving the intake alone so it will remain a constant in their testing? This is all just speculation on my part but I think if you test headers on an engine with a restricting intake then your gains are not going to be the same as when you free up some air flow going into the engine which could be the cause of Racing Beat finally seeing a gain greater than first posted.

The stock intake is really not THAT restrictive...

too bad their original claims were USED to disprove that any other company could provide more power then themselves from various mods... Borla especially comes to mind since they post an 8hp claim and then get blasted by RB's webpage and Jim himself on this forum the following week after their own exhaust made 3hp and "thats all that is possible".

Well, it doesn't exactly look like 8 hp was that much of a pipe dream after all.... see TurboXS

Hmm... that sounds like providing false information in order to sell one's products... oh, i forgot.... Racing Beat

Racing Beat has earned a great deal of trust over 35 years of building quality products for our cars, so there is a reason that they have such a following.

That said, RG and many others don't just take their claims at face value, we do actually investigate there claims for performance gains. We got to see how they test and what they tested at Sevenstock, and they are about as conservative and butally honest as it gets.

Racing Beat does all their testing on a engine dyno, which is the most accurate and consistant way to test whether or not a product makes real power. Most others, included the ones you mentioned, use either dynojets or dynopacks, both of which are less accurate and could UNINTENTIONALLY show slightly inflated gains that are totally outside Borla, Greddy, TurboXs etc.... control.

We are only talking differences of 4-5whp here betweem RB and TurboXs for example, which are inside the margin for error for most dynojets and dynopacks.

I'm not saying that turboXs doesn't have a better product, Racing Beat will be the first to tell you that someone could build a better mousetrap, but with their experience, they know how to get power from these engines, and have the knowledge and experience to make some of these arguably blanket statements on gains from intakes/exhausts etc...

no, for the full exhaust we are talking 20rwhp vs 4hp at the crank shown now with several cars and several runs for each car... thats a pretty big difference

They published their numbers with the complete intention of justifying their modest power gains. While I'm sure their testing of their products is accurate, their numbers to justify their gains are bogus. You do not just unbolt an exhaust and dyno the engine (which now runs like crap) and proclaim to the world what the max gain possible for an exhaust is - and people on this board especially continue to take their numbers for complete face value because "they are the all trusting and all knowing RB"

Now I read they themselves will be releasing a product that produces more power then claimed possible - well if their testing is so accurate they really have some explaining to do

Aye, but you've only ever heard one part of the story. When friends start a business and it falls apart, the bitterness is usually pretty nasty and vicious. It's pretty hard for the RB founder to defend himself when he's on the other side of the US.

Not saying your friend is lying, I'm just saying there is always parts of the stories left out. It's easy to choose sides when you only have one.

ddub

They weren't in business together, they merely shared ideas but both did their seperate thing. Afterwards, the guy that started RB stole his concepts and ideas, and discontinued contact with him.

Also, did you miss the part how I've talked to lots of other individuals and companies that say similar things? RB steals this ideas, or screws them over in some way. So this is not an opinion forumulated by one individuals account, it is that individual and other company's accounts that lead me to my belief.

Not that this matters, but other side of the US? I, and this guy, are in WA state and RB is in cali :P
