If you're proud of your accomplishments, that should be good enough for you. If you're going to share claims that here are difficult to believe, without a shred of evidence to back them up, just don't. We have many experts with experience directly contradicting the claims of a single unfounded and elitist poster who swears and has an aggressive attitude, who do you think is going to be more convincing?
This has nothing to do with either me personally or my general accomplishments.Instead of trying to understand why I post what I post and instead of asking and simply rest on just drawing your own false conclusions, you should try to see if this is as I say if you are interested in an fp red setup, as you have nothing to lose but all to gain in your effort to improve your setup. If on the other hand you do not own an fp red nor plan to do so, then you have no say in this thread, but you do not see me telling you to stop posting your findings because this is like how I feel about it. Actually I would support your freedom of speech and right to share your experiences with the rest of the world if you so wish to do so, even if I do not agree with it.
I am not here to convince anyone to do anything. I am posting my own experiences and findings to show what is possible with a certain setup, nothing more. The attitude aggressive or not has to do with how people behave and confront my commenting through their posts. As for forum proof, yes I agree that posted logs would stop people asking for them in ordered to believe, but unfortunately for them as I have already said more than once, I do not keep logs on the pc once a setup is done. Someone in the know does not need logs however to know that what I am saying is very do-able. For those not in the know If you merely think the simple fact that a specific compressor, compressor map and turbocharger is for instance rated to 75lbs of flow but in reality it gives 80lbs, you can realize that same goes on for the rest of its characteristics, such as the surge and choke limits presented on a given compressor map i.e.
As for Extreme Tuners, I am not a tuner in profession, nor do I tune their cars. I am simply friends with the owner of the company. I only tune my own cars/setups and help friends with theirs.

The reason the specific was mentioned here was to show the responsiveness of the turbo on the right setup.
Apart from the above when something is discussed on a forum such as this, it's good for one to give relative info to any o/p's question as I am sure that others that might be interested on this for example might as well be using their car on the road also.

I am emphasizing this because this hKS setup I built is really similar to a normal evo 9 turbo in boost treshold (i.e. spool), while doing some 70 hp more, but it is much faster in throttle response (i.e. transient response) when driving..

responsiveness for autocross setup or, for that matter, road setup, is better shown by measuring the transient response, which no one does really...

Both high gear low rpm down pulls, which show the boost threshold, spool time, and full boost rpm point to what it actually is, and transient response through gear changes should be among others two of the most important factors for circuit driving/ time attack/rally for choosing a turbocharger. The two are inter-related, if you have great boost threshold/spool time and full boost rpm point, then your turbo's transient response will be very good as well. Also choosing a dual ball bearing core affects positively the transient response and extends the life of your turbocharger.

For rallye you want response and wide powerband, although rally cars are specific in having small restrictors, and they are mapped for max power all the time which means a huge spike in tq low down and then on a flat powerband... they do run antilag though
On the road, IMHO, you want a flat TQ graph for as long as you can, with limited tq spike in the begining... this is nice on the gearbox and drivetrain, and nice for overall car behaviour. Most wouldnt agree but it is my opinion..

depends on the type of race.... Your normal road course / time attack car doesnt have to have all that wide of a powerband.. in fact any place where you know in advance what the corner looks like exactly, you can live with a narrower powerband and better gearing..

Apart from the fact that I like wide powerbands in general no matter the usage of a setup, it gives one much better flexibility and makes things simpler and more fun, and the fact that on a road car/daily driver setup where you compete with no one, nor are you after a time record, where how your setup is, is simply a matter of how one likes it, I agree with what is said above. On a road car I am of the opinion that when building a setup one should simply amplify and improve the car's oem performance and behaviour as it is.
