Maybe Smorison or Unique Autosports will pay for it, that way they can use the data to discredit RPW and use the site to push their own products some more.
Then again maybe they know what the results will be, they just use the "did you put it on a dyno, before and after, on the same day, with the same operator, same amount of fuel, same temp, same humidity etc" as a scare tactic and because they think we give a crap about actuall figures. All you need to do is go for a ride in one.
Anyone in Perth who wants to ride in a manual GPX with full RPW mods, drop me a line. Better still, maybe we can go head to head with RichardH, he's got the unique pipe.
Scared?
You should be.
oh dear, have things really degraded to this? How about we get over the size issues and the "mines better than yours" and do this in a more sensible manner.
I'm neutral in this as I do not own any RPW or UAS equipment, but I will say that I'd be questioning anything labeled as a performance product if dyno results could not be shown to prove what they do. You wouldn't upgrade all your stereo components to ones which simply said they were "loud" and "sounded good", you'd want to know the RMS wattage and frequency response, so why should this be any different for performance equipment?
Keep in mind there are two key parts to the dyno results, one is the maxium power outputs (KW and torque) but probably the more important one is the graph itself as this shows the usability of that power. You may find that a brand X performance product produces a higher KW figure, but the brand Y product provides more torque where you want it. The dyno graphs would show this and help make a more educated decision based on how you wish to tune your car.
Remember there is no "wonder fix" to dramatically improve performance, it's all a fine balance of tuning your car to get the specific result you desire. An improvement in performance in one rev-range often means a decrease in performance in another rev-range.
Gwido, although I understand the point you're trying to make, you're going about it all wrong.
Black_FTOGPX sentiments are right on, this should not be a place of bitching, or goading people into challengers. We're a small enough community without having internal politics breaking it apart.
People will buy what they think is good, however, I was a little disappointed with the fitment of the RPW extractors but in all, they worked well for me.
What I am disappointed was that there is no word of the race tune extractors, and I haven't seen mitsiman post in here for a while. Guess they're busy.
People do want to have faster cars and the like, but we've done well to not have any ego brandishing in this forum so far, we don't want it to start now.
Respect will be given when respect is due. However, people on here won't tolerate dis-respectful posts of members on here who have earned the respect of people in this forum.
These are my thoughts but I think I'll speak for the whole forum with that comment.
ok the point i make over and over again about RPW is they always have an excuse as to why they shouldn't provide DYNO results... to me this is very concerning as any manufacturer of a performance modification should be prepared to backup their statements.
Hell i've even offered to dyno their products for them (at my expense) and they have declined, its not through lack ot trying on my part.
as the owner of this site
as the national president
It is my responsibility to ensure that members are given accurate information on all products that performance shops claim work.
It is no secret that i spend a lot of time with Unique AutoSports and it is no secert that Unique AutoSports are my preference - i do deal with other companies but only where i know it would be a waste of time and money buying from Unique AutoSports. (tyres / alternators / etc).
All Modifications Unique AutoSports develop MUST:
* be dyno proven
* give me a copy of the dyno
* be tested on multiple cars
* be realistically priced
now lets addresss some of those
dyno proven
Dyno results before and after done same day and as quickly as possible between the runs. At least 3 before and after runs (min 6 in total) are done to get a good idea on power gains / loss
tested on multiple cars
At a recent dyno day without knowing anything about a car they put the intake mod on the car and it made a substantial gain - can't remember the exact figrues but it will be in the thread
When developing the UAS engine pipe we used 4 cars 2 tip mivec's 1 manual mivec, and a GR. it was determined that it was a risk to sell this product to GR owners and their money was refunded.
As my reputation is at stake as much as Unique AutoSports i ensure the products go through strict quality control and there is no hype and bulshit associated with the sales. The only reason i chose Unique (apart from them being in sydney) was that they were (and still are) committed to quality and will adhere strictly to the conditions i place them under.
As an example of this, before i had even seen the Brake Master Cylinder supports (the prototype i have been using for a long time) they returned the entire batch at their expense to be rebuilt and it has now been 7 months since the first one came off the production line and we are only just getting quality now. This they have done at their own expense without even asking me if the quality was acceptable.
I am not slandering RPW here nor am i promoting Unique AutoSports i am simply showing the difference in the way the two companies operate. Why? because it is my responsibilty to present information i have to all members to ensure those who may not be as experienced as others can make informed decisions based on the information available.
RPW's reputation nationwide is a company that has great ideas just rough on the finished product, i have heard this from companies who have dealt with RPW in the past. I will say that again they have great ideas...
anyway Gwido, next time before you go making accusations you should check the facts.
Sorry, I didn't think I was slandering UAS or anything, just making a valid suggestion (aka my two cents). If you choose not to listen that is your perogative, and if it annoys you, maybe you should ask yourself why...
Common sense says that full extractors, with a dump pipe that is almost identical to the UAS item, will provide better breathing. The extractors themselves will add more power to what UAS is offering. (Read: More power than the UAS item, not saying the UAS item doesn't add power.)
As for mitsiman, he can be reached on the MOGWA website any day of the week, he is probably sick of the same comments and questions everytime he visits this site. Race extractors, as he has said before, are a custom made job and cannot just be ordered by mail, they need the car.
All I am saying is why do you need dyno results, it seems to be the only thing that is stopping you all from buying RPW products? No one else offers the same products, and surely enough members have given positive feedback to confirm they work and work well. Ok, there was some weld splatter on the extractors, but this is easy to remove, but you cant see it anyway when fitted.
I'm not saying my car is the fastest (sorry rich) i was just suggesting we go head to head for a real world comparison of the two products. Win or lose, we will find out the truth.

Because without them you can't validate what they actually do and because personal opinion can be wrong and can differ between people.
A good example of personal opinion is exhausts. Many people get the feeling the performance of their car has increased because the exhaust is louder. As we all know this isn't necessarily the case, in fact in some instances, a different exhaust could lead to performance decreases (e.g. too large an exhaust), yet it could still give the appearance of increased performance due to increased loudness. Dyno's remove the human error of personal interpretation.
Probably the most important reason for doing a dyno is to produce the graph which shows the difference the mod makes to the torque and KW curves. As I mentioned in my message above, there is no "wonder fix" to dramatically improve performance, it's all a fine balance of tuning your car to get the specific result you desire. An improvement in performance in one rev-range often means a decrease in performance in another rev-range.
So someone wanting to increase performance down low would need a differently designed set of extractors and exhaust to someone who is seeking more performance at the top end. While both may improve performance they do so in different rev-ranges and this is where the dyno graph comes in so you can tune your car to get the result you require in the specific rev-ranges.

(a) one could be a better driver the the other
Just race each other around 3 times for consistency, & then swap driver.

Your post came across in my eyes as a really aggressive post and you seemed to making the statement that we all thought like that (and you still are)
That is what annoys me the most.
And to be honest, Dave kept saying that the race tuned extractors were coming soon when I was tossing up waiting or getting the already available street tune extractors. I got tired of waiting after 6 months and got the street tune ones, I never got wind that they were ever custom job tailored to each car.
Also, how can they be customised jobs when they are selling the products to international buyers, that just isn't possible. Their web site still appears to have race tuned length extractors as one of their products off the shelf, just a modification to the street tune design. What you're saying doesn't make sense to me.
Don't get me wrong, I'm happy with what RPW have produced. However, I don't like it when I get labeled what I'm not.
Oh, and why people like to see dyno results??? It's the closest thing you can get to a scientific method of proof. It's a measuring device. Like it or not, some people like to see some of proof that it works, especially with products that take a while to save the money up for.
Why does everything have to have a winner here, oh right, we're in a car forum =PPP =)
(And yes, this is as active as anyone has seen me in a thread =P)
How about we get over the size issues and the "mines better than yours" and do this in a more sensible manner.
Yes, it would be nice if we could eliminate the "size issues" some people have, it would help make these forums more amicable.
