That may be relatively low, but it's still very high in my opinion. On 85 degree days (as hot as it gets for any length of time here), while doing autocross runs (which involve very little airflow over the radiator because of the low speeds) going full throttle almost constantly ALL DAY I had an IAT of 105F.

Y'all need that intercooler somethin fierce.

 

Definitely on the intercooler, but this has been the lowest my IAT has been in over a month, so I'm happy.

 

Okay, nothing out of the ordinary here. You are non-intercooled, so 155°F intake temps at slow speed is understandable. This is nowhere near non-intercooled (even intercooled) temperatures of other FI systems.

Just to reiterate, the IAT sensor is plastic and heats up in stop and go traffic when under hood temperatures spike. This causes the IAT sensor to read high.

I am wondering if the location of where he mounted his A/T cooler has anything to do with the the elevated intake temperature he is experiencing..... I had put one on a GMC van and it was very effective at dissipating heat to the extent that it lowered the temperature of the engine coolant as well..... I mounted it in line ahead and in front of the radiator and could feel that the dissipated heat was accumulating inside of the engine compartment under the hood and much hotter in that area than before.... I have noticed that this problem seems to be of more concern to owners of cars with automatic transmissions.

 

now just a random thought but would this intercooler kit be more efficient on a turbo kit that the FMIC that come with the kits?

 

Going to eventually see if a combination of a vented hood and the TMIC kit will lower the temperatures big time - just a matter of not having the funds for such items right now.

 

mustang dynos measure true wheel horspower, unlike dynos that hook up to the hubs. i like worst case scenario numbers, it helps me keep things realistic. i dont drive without wheels. and the wheels cause a loss in power (hence why hub dynos and mustang dynos usually have numbers that favor the former.) that i like factored in.


but i agree: dyno numbers mean nothing if you are not using the same one.

 

I will wholeheartedly agree with OJR here, for a non-intercooled FI setup, 150F IATs really aren't that bad. Cooler is always better, but I'm sure without my FMIC I would be running temperatures WELL into the 200s. My intercooler does get very warm to the touch on the hot side, even during regular DD duty. The cool side stays cool, however.

One other note, my IAT sensor has been relocated with my turbo kit, to a place a little further from the engine, so heat soak is probably not that big of an issue on my setup like it might be on others.

Long story short, the intercooler is a VERY good idea, even if you're staying at low boost. I applaud Kraftwerks for coming up with this elegant solution. Very cool guys!

 

Just need someone to try adapting the KWSC TMIC to a turbo kit like Kylerwho was asking and see how that turns out - if it works out well it could be a great kit for turbo owners who don't want front mount or to lose their fogs, etc.

 

I dont know if that small intercooler is sufficient enough though to cool for turbos.

 

mabe a double intercooler setup? sounds kind of silly... never heard of one... with good reason im shure.

 

While speaking of intake temps, has anyone considered running a CryO2 system in conjunction with their supercharger kit?

Design Engineering, Inc. - CryO2 System & Components

For the kit there is a pipe with a metal tear drop like shape inside that also the CO2 run through it and cool the passing air. That should work wonders for reducing the intake air temp and even better with an intercooler. Here is a pic.

 

Systems like these were in the J.C. Whitney catalogue a few years ago but not for very long... It would be great for drag racing but so would an air to water I/C pumping ice water and much cheaper to operate.... I had a refrigerator in a travel trailer that operated by a propane burner heating alcohol that somehow circulated through coils or something.... It worked real well .... I am thinking that the same principal could be employed using heat from the exhaust system... I am going to have to do a search about that type of refrigeration.... In fact my brother in law has an electric refrigerator made by Frigidaire in the 1930s that uses the same process..... All refrigerators worked that way in the old days.

 

does anyone run a torque damper with their kwsc? just wondering if there's room for it.

 

I am not sure about room but I have read that stiffer motor mounts are the preferred way to go..... With the standard KWSC set up, light weight wheels and street tires I am not having any problems though the engine moves around a little if I don't lift my foot to match revs when shifting at peak power in a turn..... I Know not to do that and don't so it poses no problem.

 

I've read about alot of people with turbo kits (around 165) tearing up their motor mounts, that's why I wanted to throw one on before I upgraded, but I doubt it will fit. Also, I really don't want the rattles associated with stiffer mounts.

 

Warning: I'm a total noob here and pretty intimidated reading through all these posts.

I'm interested in the KW kit. I just want some more power in my daily commuter car. My Fit is 2007 Base AT.

If I get the KW kit, will I:
1) Require any further upgrades? (brakes, intercoolers(?), exhausts...)
2) Require more frequent or complicated maintenance?

Oh, and will it make the car "loud"? I'm not exactly a fan of that...

Thanks for any and all help, cheers!

 

1. No, but you should probably get a transmission cooler.

2. Only extra maintenance would probably be changing the Rotrex oil at the intervals stated, and changing the belt more often than you would normally.

From my experience, I don't know how it sounds coming from a stock muffler, but exhaust volume is probably the same or maybe a little quieter than stock when using aftermarket. Noise from the engine will be a bit louder due the supercharger whine & intake noise - but it's still not as loud as it was when I was using a SRI. Overall my car w/ KWSC & H-fit exhaust is pretty quiet until WOT.

 

I have the base kit on a 2007 M/T car and can tell you that there is no additional maintenance but it is advised that you keep an eye on the belt adjustment.... The only upgrades on my car at present is lighter wheels and a freer flowing axle back exhaust pipe and muffler and these things I had put on before installing the KWSC.... I had an AEM intake that I removed when I installed the kit and there is less noise coming from under the hood now than before even when I am on boost..... I have to admit that 100 + degree weather hurts the performance but should not be of concern where you live..... It is just like driving a stock Fit until you step on the accelerator pedal, you have to use high octane fuel and the additional fuel that you will use is worth the fun that you will have.... It pulls like it would with a larger engine and there is no quirks that make it feel like anything but a factory installed engine with more displacement..... The installation manual and the technical support online or over the phone makes it possible for a person with mechanical skills to do their own installation..... Yeah I like my car a lot more with the thing and I already loved it. .

 

Thanks very much for the quick response! I didn't know about the fuel requirement. This helps a lot!
