The folks at Jackson Racing can get 40 more horses out of a d16 civic with their bolt-on supercharger. $2k. No turbo lag. (not to mention the 170+ hp from a '03 civic si!) Lets all give them a little note expressing our interest in having one developed for our Fit!
I shot them a nice message. You guys may recomend to them that the L may be the next D. It may be in alot of other cars and could be a large market. Just beg for the boost, 5psi would be pleanty on this car to make it alot of fun on the street.
That would be terrific, it however will depend on the Internals of the engine. Hether the Rods and even the Pistons can handlke the added pressures. If you check the stock compression ratio while not being real high it is in the 10-1 range. Thsi tells me that the internals will be a major factor in any bosted application. However a roots type blower would be a perfect "FIT" for the newest Honda Tuner on the block. A typical 25-30HP gain would be tremendous on the Fit. Like most Hondas they lack torque and a roots type blower would give that added oomph down low in the rv zone as roots type super chargers are static in that add boost at any rev zone even at just off idle. Other thoughts would be of the driveline and other areas to see if they too could handle the added power. I predict the Honda "FIT" will be the savior to the Tuner World. I like many are turned off with the exotic super cars and their huge prices. The Tuner Craze started with hand-me-down Civics and Accords. These low budget rockets are what started the high tech power revolution and the "FIT" is just what the Tuner World needs to jump start an ailing industry. Not that many grocery baggers, or burger flippers can afford the TT Supras and Evo X that we all see in the Mags/Rags these dayz. Just tonight while flipping thru the super market mag rack I eyed the price of the latest "Import Tuner" Rag at $6.99..like no-way ....am I gonna pay that for mainly advertisments...The Fit is the Cure for the Summer time Blues....

amen to that...The Fit is gonna be hot and with parts that will come out soon for it will be overwhelmng depending on sales here and when more people get it

I wonder about internals too but from the JR website:
"Because of our unique bypass valve design, engine life is not effected. Our system is so efficient and produces such useable torque, that you are rarely at full throttle for any length of time. When you are at cruise speed or idle, the bypass allows the engine to breathe normally, no boost. Only when you depress the throttle aggressively does the bypass close and you have an instant 6psi of boost. Consequently, with our unique bypass valve and reasonable boost, engine life is not effected."
and the recent issue of HondaTuning (p88) has an interesting letter response regarding boost on modern engines. To paraphase, low compression for high boost engines applies to pushrod American iron. "you can definately run 10.5:1 or 11:1 pistons in yours, even at 12 psi of boost...don't let anybody tell you to do things the archaic, domestic way."

u should worry more about how u're gona have an engine management system first. low compression=good for boost, to a certain extent, same goes for high compression.
u can boost any car, but the real problem is how u're gona manage the fuel/ignition/cam angle/etc.
if anything, u should shoot Hondata an email first. JR works with Hondata and depend on hondata's tuning to get their s/c's to work on Hondas.
Hondata will have a bit of difficulty b/c of the drive by wire system. just be patient.

also from JR:
"Q: Do Chip and Cam upgrades help with the Supercharger? Back to Top
A: These upgrades are not recommended. Chips are made for Normally Aspirated engines and the fuel map is manipulated to make the car run leaner and the timing curve is slightly advanced as well. Both of these can and will be detrimental to any forced induction car. A fully programmable ECU along with larger injectors however is a different matter all together. We have tried a number of different cams in our applications as well and have never found anything better than the stock cams. We have tried Type R cams in our GSR and lost 10HP. We have tried GSR cams in a Type R and lost 10HP. In our Civic SI we have tried 3 different sets of cams and lost anywhere from 10-13HP. On one set however we were able to tune a 13HP loss to only a 3HP loss with cam gears and 3 hours on the dyno. There may be a set of cams out there that works but we have never found them."

yea like I said just hope hondata will have something for the fit
These new Honda engines are now run by a computer regulated Throttle. Before there was a cable from the accelerator to the Throttle (butterfly) body. Now there is no cable, but there is a Wire from the pedal to the computer back to a sending unit which controlls the throttle. Any power upgrade will have to solve this huge issue. Most of the Tuners that have worked on the new Civic Si have dumped the complete wiring system and gone back to an older wiring harness. I am sure that companies like Hondata will come out with a stand-alone type engine management system. There is even talk of a piggy back module that will eliviate this "throttle-by-wire" Honda system. As with the interesting posts above about the supercharger for the Fit I feel confident that a roots type blower would be the way to go for modest performance gains for the Fit motor. Tuners are just now starting to tinker with the Fit engine, and we will see mods coming soon. Stay tuned for a resurgence of the Honda Tuner craze...yippy...

thats what i said above. DBW issue needs to be resolved first. retrofiting throttle by cable isnt really a fun thing to do, and even getting the ecu to adapt to such change will be difficult.
as for the piggyback system, it is a bit easier to do but will not be easily adapted to any setup. the piggyback system is working pretty well on the Comptech S/C kits for TL and TSX. but any changes to a setup would require a new reflash to the piggyback if its not a tunable type.
only time will tell wat holds for the Fit performance-wise. building a supercharger or turbo kit is not hard at all. fabrication of hardware would only take a month or so. but the main thing is getting the tuning and ECM system to work with it. that can take years. (TL/TSX piggyback took 2 1/2 years)
