NetViper said:So Lud, in other words... for street driving, the Comptech and Gruppe M are better solutions because of the low end torque. For track driving, the BBSC will give the most performance. Sound about right?
I think you've pretty much answered your own questions with respect to the boost profiles. Nice when the measured data conforms with the theory.Lud said:I'd still like to see answers to my questions about the boost profile, aftercooler or other mods recommended and the benefit derived from them, cost, etc. but I think it's safe to say that while the BBSC now produces more power than stock at the low-end, the fundamental torque curve characteristics relative to the other kits (linear increase vs. relatively flat) remain unchanged.

Lud said:The graph shows dyno results, but being a car geek I am still curious about many technical details, which the web site is very light on.
How over-driven is the 2000 blower in this application (meaning, what would PSI be at 8000 RPM if it did not waste any boost)?
Above what PSI does it waste boost?
How much effect is there from heat-soak with prolonged high-RPM boost (such as at the track) with no aftercooler?
How much does the aftercooler improve performance?
How much does the aftercooler cost, and it is officially supported?
Sig said:Seeing that Mark rarely visits the site, it would be a more efficient and effective use of time to contact him directly either by phone or via email. Waiting around on a forum for all the right information to land at your feet can be frustrating.
Ryanmcd2 said:Lud just spend the $6500 and you will see how it works. That's what I was told. Good luck getting all the facts about it. That webpage has about 3% of the info I am looking for, more of a sales add then anything else.
NSXTech said:Ryan, Well- you have one fact correct- almost. The website is about 25 per cent complete, rather than 39- but it was my choice to start with what I had time to finish in between phone calls and installs. If I had waited any longer, the critical drumbeats just get louder. If I come over with what I have so far, the critical drumbeats get louder. If any one who works for me or one of my dealers actually said, "just buy it and find out for yourself", I would be shocked and dissapointed. I suggest you have embellished just a little. If not I apologize TO YOU, and FOR MY rep.
To answer the most asked about relevant question, by the closest thing to a voice of reason, it would be Luds question about overdriving- how much and what levels. None, and None.
The 2k, despite the opinions of some here who think the 2k upgrade is a scam, makes more power lower strictly as a result of CFM, which equates to two very minor issues you may be aware of. Air and fuel density. Boost may be boost, but 6psi at 800 cfm, and 6 psi at 1150cfm, are night and day animals.
More info on all aspects of the newer system will be forthcoming. In the meantime, the site went live because several magazine and tv stories have flooded our phones, and our e-mail and tech support needed a central home. That is why the site is up. For those who think it lacks enough info to justify a purchase, please,
PLEASE do not do so yet. I have been serving the NSX community longer than ANYBODY on these pages- 11 years to be exact, and will be here for many, MANY more. Every other kit coming out sounds REALY good, but who are the builders, what are their customer treatment ideals, and just how much NSXpertise do they possess. Experience?
Again, the voice of reason- Lud suggets, there are many new kits out there and they do different things for different people- ask questions and choose wisely.
