care to elaborate on this? are you saying that a/t fit's can not handle the upgraded injector package? please shed some light on this Oscar because there are alot of a/t owners that already have headers/test pipes and that would mean they would have to remove them in order to get the carb kit. 3 thousand dollars is an awful lot of money to spend for 25 - 30 hp with no hope for additional power.

what brought you to this conclusion if this is true. again specifics please as it seems like this was slipped in here without any supporting info.

 

Considering this in the section describing both base and High boost. It may just mean that AT cannot run the 10lb kit once it is available. I say that becuase it comes a couple lines after he says a base and High boost kit are available, AT can run the base kit.

 

Oscar how much HP loss is expected at altitude compared to normal loss? Obviously it is relative I am just wondering if you lose a higher percentage with the kit than just with a stock motor?

 

If he had the 10psi dyno it would be posted already. That information is going to be released soon tho.

 

we are just as excited/impatient as the last crew that wanted to know about the 5psi kit but this one is more for the ones that wanna get EVERYTHING we can out of that lil motor...lol

but i got a quesiton for you (nooB one)
do you have BOV that you can hear when you shift? if not would have ing one make the car breath better and give you more hp?

 

as stated before, The kit comes with a Bypass valve, so you will have the pshhh sound

 

Premium is 93 Octane around here. I tend to use Top Tier gasoline, but there is a lot of cheaper gas around with 10% ethanol. Is there any problem burning it occasionally with 5# of boost?

 

Now that the pre-sale has ended, when can we expect these kits to begin shipping? I need to know if this will arrive in time for me to install before our only show of the year on May 24th!

 

I understand the use of the Powercard/Supercard for CARB purposes, but i still do not believe its the best method for the non-CARB applications. As its similar, from what i'm reading so far about it, to Comptech's Black box, JR's Powercard, Cybernation's Guardian E.I., TRD's black box, etc. All did not give the optimum performance, and yet promised all the same stuff like the Supercard is promising.

Are there tunable solutions for the setups? ie. Greddy Emanage Ultimate? Or perhaps attach the EMU in conjunction with the Supercard? Was there an attempt at getting Hondata to help with just reflashing the ECU with the tune instead of just piggybacking a box? Sure, the Supercard will work, esp on your test cars, but just wondering if there are other methods out there.

Also, 10psi on stock MAP. I'm assuming the Fit uses the same MAP as most other Honda's. 10-11psi is usually the limit where the sensors stop reading accurately. its borderlining for comfort personally, as if there is a slight chance to run higher boost than actually is read, ECM wouldn't know. I'm sure u already know that, but just also wondering if you should look into using the RDX's stock MAP sensor as a replacement or even Hondata's 4-bar sensor. Its more about getting the proper MAP reading and having a good margin in case you go over the specified boost level unintensionally.

Please enlighten me more of the engine management aspect of the L15 . A supercharger i tuned on was supposed to only run 11.5psi, but somehow came out to 13.5. luckily, we were using the Greddy Pressure sensor that reads up to 3 bars.

Can't wait to see these setups in action, i'm also watching your S2k setups as well. A friend of mine is really interested in doing it soon.

 

A stock Honda map sensor will stop reading at 12 psi so 10 psi should not cause any trouble at all.

It is my understanding that the supercard/powercard is only designed to modify fuel curves like an fmu would do. Is there any timing retard done?

If your timing is too far off you can detonate and blow the engine, if you go over 12 psi on a stock map your ecu will just put you in limp mode. I would be more worried about timing.

 

Are we talking 12psi of additional pressure or 12psi period? atmospheric pressure is already approx. 14.7psi.


Timing would be a concern of mine as well. However, on the flip side of that coin the Comptech kits just use their ESM box and an FMU and don't alter the ignition timing either.

 

We will be working with Hondata on the High-Boost. We have not said we would be using the SuperCard on the High-Boost. The SuperCard is designed for low-boost applications, where a timing adjustment is not needed. The SuperCard does its job very well. Our software is proprietary to us, so I do not know how other companies have built their software. I recommend checking out the first post of this thread, and read up on the SuperCard.

Of course we understand the limitation of the Honda MAP sensor, and we build in a buffer. According to all of our continuous data logging, the MAP sensor is working with ease. We run 10 PSI with our Hondata Reflash on the S2000, and it runs VERY well.

If you run an inefficient supercharger too high, you will get erratic boost numbers. This is caused by the excess "boost" actually being hot air. The hotter the air gets, the more it expands. Roots superchargers do this, once you reach 9-10PSI.

Considering this is a 'Forced Induction' Forum, it's safe to say that we're talking about boost, not atmospheric pressure.

 

If there is any chance of testing this kit with an Intake Mannifold, I know people have talked about it in Thread 2.0 but any ideas as to the results? And as far as loss of power like the 50hp lost from some exhaust parts on your S2K kit, do we need to steer away from anything on the fit that you know of yet? Thanks

 

I believe he is testing in California, and pretty much all we get is that ethanol watered-down gas, iirc.

 

The kit recommends 91 octane so anything more won't change anything.

Higher octane always helps reduce detonation but at 5psi and 121 whp 91 octane is fine.

The 12psi is above atmospheric pressure.

OJR great to hear that the high boost kit will have proper timing maps as well

 

Getting close to the end of April

Still hoping it is going to ship in April!

 

hell yeah!!!! *in arnold voice* more POWAH!!! (hopefully...lol)

 

Thanks for the explanation!

Everyone should go the high boost setup F- low boost.

 

Will the Hi-boost upgrade allow the top speed limiter to be removed?
