they both r good, which is cheaper

Turbo with greddy e-manage system and all necessary hardware is $3500 which will produce 186hp to the flywheel, 150-160hp to the wheels, supercharger kit is either $3500 for the 5lb kit, which produces 123hp to the wheels, or $5000 for the 10lb kit which produces 157hp to the wheels.

Ok this is why I think you're being slightly stupid about all this nonsense.

The fit is just a tiny car. It doesn't NEED 250 whp to be fast. Can you imagine this thing at 180 or so WHP? It would be a ******* animal.

You mentioned the CRX SI was a really fun car to drive. This fit could be your next CRX with a modest power upgrade. Slap that JRSC on the fit and it will move.. a lot more than your CRX most likely did

eL

Not that I disagree with you elohel, but the car does weigh 2400lbs.

stumpyd2002

I agree about the wight/power ratio. My crx was lighter than the fit, but old muscle cars had 400-500hp because they were so freakin heavy! So I understand where your coming from, but I just dont know if the 180hp in this car would still be enough to make a few mouths say"OH MY!" as I smoke their mustang off the line. I am thinking turbo would be better. Same hp as the $5k kit supercharger for $3500. Just a thought right now. Im currently laying out blueprints for the interior to be modified. Should be interesting if a few things come through for me.

Directly from Siphon the magazine, who interviewed Jackson Racing: "Preliminary dyno data taken before CARB approval reveals the 5lb supercharger kit produces 126.13 hp and 114.77lb-ft of torque-a gain of 35.49hp and 27.26lb-ft over the factory Fit's baseline numbers. Jackson claims the CARB-approved supercharger kits will be rated at 120hp." END OF QUOTE. So i dont know what "JDMChris" has on his Fit, but my numbers were a whole 3hp off. Its 126, not 123. Buy siphon and check it out for yourself. Page 47, top right corner in the grey box.

SAME ARTICLE AS THIS ONE: "The 10lb upgrade kit with JR Catback exhaust delivered 157.8 wheel hp and 142.6 lb-ft of torque..."

that says preliminary dyno data,which means they have probably fine tuned it a bit since then.i work at a honda dealership and the buzz around honda is to wait and buy one next year i guess there bringing out a another version,si?mugen? dont know.we have a guy in our parts dept that has white 5 speed,intake,exhaust,and a 50shot n20,ive riden in it,and damn! that thing freakin moves.theres another guy at my work that has a stock 95 dsm turbo,last time they raced the fit kicked his ***,i think theres going to be a huge aftermarket for these cars in a few years.

Who cares... Those Dyno Sheets are from LAST September/October. Oscar Sr. and Jr. were both Thrilled with how much power it made on my car. THEY dyno'd my car. Header back exhaust is the only mod. Im pretty confident I will break 180whp

Hey JDMchris, im not trying to dog your fit. TRUST ME, IF I COULD, I WOULD DO THE SAME AS YOU! But unfortunately I am in ohio, and tuner shops that ACTUALLY know what they are doing is very scarce in my area. But now that you told me that, IM VERY EXCITED! Honestly, reading that article more DEPRESSED me than IMPRESSED me. I was expecting more from a supercharger, and apparently, there is MORE, MORE HP! Thats great. I want one but in reality I have no one nearby that would be able to install it for me. What brand header-back exhaust do you have? I was kinda pissed when my dc sports header didnt come with a down pipe. I was expecting more from a company like that. My cat-back is a skunk2 mega power. I NEED TO REPLACE THE CAT!! And get a downpipe. any recommendations???

JDMchris.com

The install is pretty DIY. I have a megan racing header, megan racing downpipe, megan racing b-pipe and tanabe axle back. Megan used my car for R&D so I got all their stuff free.

So the install on the supercharger was DIY? Or did you mean the exhaust? I have installed all the parts on my vehicle and they were really simple installs. What exactly is a b-pipe? is that what replaces the cat? or the pipe that goes from the cat to the rear axle?

Yes the SC is a DIY The Bpipe is the pipe from the cat to the axle back.

Thats great news! So you are a little over 140 whp with the 5lb kit. The turbo on http://www.a-jracing.com is rated at 6psi and does 185hp to the flywheel, 150 to the wheels. It comes with a greddy e-manage system and all necessary items for the install including b.o.v. and intercooler. Its $3500 as well. In your opinion(i know you went with the s.c.) what would be a better deal IN THE LONG RUN? I always thought turbos were better since they didnt draw power to make power, but reading on the new rotrex s.c. systems it sounds like they dont use that much power at all. What do ya think?

my SC has a BOV however since these new rotrex units dont put off alot of heat, there is no need for intercooler. I think Turbos are nice, although i HATE turbo lag. There is absolutely NO lag with a SC. If i Had to do it again, Id definitely go SC over turbo.

stumpyd2002

So you have the sound of a turbo with the b.o.v., and the spontaneous power of a s.c.? Thats awesome. Im serioulsy pumped about that now. Thanks so much about all the info. I am 23 and have been in love with hondas since I was 16 and bought my first civic. I have a dream for the fit and look forward to seeing it fulfilled. Thanks again for all your advice.

turbo of course but puts more stress on the engine

I bought my Fit to use as a great daily driver to get me through college, but even before I bought it I planned on supercharging it when the warranties ran out. 180hp in the Fit would be nuts I think.

Now I'm thinking I may not wait another 4 1/2 years for my warranties to run out. Once I graduate and get a decent job I may go ahead and supercharge it.

Ok, I see all the posts about the 2 SC kits the 5lb. and the 10lb. and yet I only see info in here on 1 of the 3 turbo kits they are planning on releasing which is the type S kit which is the 6lb. kit.

So lets look at both the dyno provided by JDMchris and the one from A&J Racing in the same post.

JDMchris first with the Jackson Racing Super Charger 5lb. kit

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by JDMchris.com &raquo;</TD></TR><TR><TD CLASS="quote">

</TD></TR></TABLE>

Next the A&J Racing Turbo 6lb. kit



Looks pretty close to me.

According to A&J Racing they will be classifying 3 turbo kits:

1 - Type-E (for emissions) (6lb. No inter-cooler, price not yet set).
2 - Type-S (low boost kit) (6lb. kit $3500 not set in stone yet, with inter-cooler).
3 - Type-R (high boost kit option) (10 lb. kit, price not yet set).

Here are 2 points of interest to me at least.

On the SC the baseline is at 100.48 WHP and 95.18 ft. lbs. TQ
On the TC the baseline is at 90.31 WHP and 89.91 ft. lbs. TQ

So it looks like the comparison starts from an uneven footing right from the get go to the tune of 10.17 WHP and 5.27 ft. lbs. TQ

Jackson Racing has already determined that their MT drive-train loss was ~13% which put their first dyno at 95 WHP. However this was NOT the Fit JDMchris has.

This makes it look like A&J Racing had a MT drive-train loss of ~17% which put them at 90.31 WHP.

Since we already know that JDMchris has done other mods which raised his baseline to 100.48 WHP we can only speculate at his MT drive-train loss %.

In any event the final numbers came in as:

On the SC the Max HP is at 142.79 WHP and 123.82 ft. lbs. TQ
On the TC the Max HP is at 146.44 WHP and 138.31 ft. lbs. TQ

So in the end we end up with these gains:

SC 42.31 WHP and 28.64 ft. lbs. TQ
TC 56.13 WHP and 48.40 ft. lbs. TQ

Since we don't want to assume the MT drive-train loss for the Fit JDMchris has these numbers are all we have to work with for comparison.

What we can figure from this is the HP at the flywheel for the turbo which would be:

176 HP at the flywheel minus ~17% MT drive-train loss equals 146.44 WHP (Wheel Horse Power).

That means a gain of 176HP - 109HP = +67 HP at the flywheel.

It's too bad that we don't get to see dynos for 2 identical vehicles (with the same drive-train loss) on the same dyno under the same conditions going head to head with no other mods to skew the numbers one way or the other.

Then we could really see what each one does.

Personally I like both products for different reasons and I'm not trying to make one look better than the other. I'm just sharing what I get from the info available.

My warranty will be up next year since I have close to 20,000 miles on mine already so I'm looking at options.

Feel free to correct anything I got wrong. This is what I'm seeing so I thought I would share it.

P.S. Hey JDMchris, how's it going? You should recognize my avitar.

Turbo "lag" is a bit of a misnomer. It's really more of a spike.

The idea of turbo lag comes mostly from cars that are already equipped with factory turbo charging systems. The owner then swaps the factory turbo out for a larger unit, moving the power band further to the high end of the rpm range, thus "losing" power where the old turbo would have already kicked in.

Adding a turbocharger to an originally normally aspirated engine will usually not make you lose any power. It's just a matter of when and how hard the added power will come. With a small turbo and low boost, such as any mass produced system that is, or will be available for the L15, lag will not be an issue. This is especially true for our drive-by-wire cars because it's already calibrated to give you the feel of more power down low by adjusting the throttle position.

SC will probably be easier to install than a TC. Less pipes to deal with plus the bay is pretty tight. I think either will make the car more fun to drive. I personally prefer the sound of a spooling turbo over the whine of a supercharger. But that's really superficial.
