What do you mean ???
35 horsepower for $2800 is steep. I’m gonna stick a leaf blower on mine...Water-to-Air is worth looking into. I discussed this with the shop that would be working on my car. I have an old air-water intercooler in my garage that I was going to use on an old Subaru project back in the day. Never did use it. The shop mechanic stated that the air-to-air would be much simpler to setup and the air-to-water intercooler is best used on a track, where you can apply dry ice to the tank. I like simplicity so.Is there literature on intercoolers mounted outside the engine compartment? Given the comprehensibility of air, I think it would lower efficiency at the intake. Dunno. Worth looking into?
How about a water cooled intercooler? A friend of mine has a Dodge Challenger in which the supercharger is water cooled with its own radiator. Wicked!
A couple of things around this. You are correct on saying that the stock ECU is limited. I have been asking around about this kit on forums, Youtube, etc. I have gotten in touch with a gentleman who has this kit installed on his Toyota Sienna. Exact same kit. He knows of two other Sienna owners that has this same kit. He shared some interesting information with me earlier today.Intercooling is key! Corky Bell's books are awesome!
Now, this hardware and plumbing aside, what are the software options available? The stock ECU will likely have very limited ability to adjust fueling and timing based on just O2 sensors, IAT sensor and knock sensor. Even though the 2GR-FE has forged crank and con-rods, ECU remap will be of ultimate importance.
1) The kit runs 'ok' without any tuning being done on it. Ok meaning that air/fuel ratios will seem to be ok for the most part and no drivability issues.
2) The kit will run better with some type of engine management as you stated.
The supercharged Sienna guy (SSG) said that he has his Sienna tuned with an HKS Fcon and said he can feel that his car has more power. He talked one of the other supercharged Sienna guys to get an HKS Fcon for his. This other guy would not get it at first because his air/fuel ratios were good but he went ahead with the purchase anyway. His supercharged dyno was 260whp. After using the HKS Fcon to tune his supercharged Sienna, he had 295whp. Both of these setups are with the top mounted intercooler utilizing a forward facing funnel setup that comes with the kit. Apparently the Sienna has the space to use this. So, yes, the HKS Fcon is one option.
I am going to go with having my stock ECU reflashed by R9K tuning, based on how my stock ECU reacts with the kit. I have faith that he'll do a good job so we'll see how that goes.
You can see a little bit of discussion about this on the Siennachat forum ~~> Supercharged Sienna
The guy I was talking to about this is not on the forum though but the two other guys I believe are. I am 'Myxalplyx' on there as well. I just joined! /forums/images/Rav4World/smilies/tango_face_smile.png
Nope, not to the intercooler in the foglight. Unless you are asking someone else. My setup is still the same. Slow, slow, SLOW progress on my part. Still trying to sort out my check engine light for too much fuel (Maf sensor diameter issue). It's in the shop now and I'm trying to get that resolved so I can take it through Motor Vehicle. No space for front mount on this vehicle. You'd have to remove your front bumper to see what I'm talking about. Originally, this is what I wanted to do.Did you ever open up air flow to that intercooler?
No justification! Don't do it. Not recommending anyone do this. Actually, I don't recommend ANY modifications. Leave your ride stock. 0It seems hard to justify the cost for 5psi. What is the compression on a 2gr?
I am using 440cc injectors with the factory ECU... no real problems. Tip-in enrichment goes rich, as expected, but the ECU is able to manage fine in closed-loop (hovers around 14.7:1), and goes appropriately rich under boost... maybe even excessively rich (I see down to 10.0), but I am not complaining, since it isn't too lean. No stuttering. There is carbon on the tail pipe, so it could be adjusted with a piggyback, I assume. I bought an FIC 6 for that purpose, but have not seen a real need for it yet. I installed a wideband sensor on each header.
Awesome update and thanks for the pic too! Hope all goes well for testing and hopefully you get the injector CEL worked out. I'm about to install a set of 440cc injectors for my E85 tune and Tundra TB, so once I have some feedback, I'll update you.I just wanted to keep folks updated on any recent changes.
That's all for now.

I'll be hitting up the track this Friday. It's forecasted to be some morning showers but with only a high of 66F, should make for a decent night of racing. If the drives well up until then with no issues, will test it out and see how it goes.
Best time is in my signature. Will see....
That's all for now.
Much appreciated Blogson. I have a lot of respect for the 'old timers' on the on th3 board. (Yeah, guess I'm old timer too). I've included a couple of pics I took today so you can see a little how things look from inside the foglight area and how we tried to 'seal' the air inside the shroud to force it through the intercooler. We almost decided to trim off the inside of the foglight to make for a 'hole' rather than the little pieces protruding into the incoming airflow. I decided against it, in case I go back to being N/A (Ex: Supercharger fails). I may want to install the foglight again someday but it's not likely.Many thanks for the update. Even though I am not going to do any of these mods to my '11 V6, reading of your experiments and progress is very interesting.
I had the HKS supercharger on my rav for a few months and removed it. OV tuning can program the ecu to run the stock injectors and plenty of fuel. You will have to buy all the software and stuff and wait weeks at a time for a tune adjustment. Very little help on how to use the software. I would not recommend running this kit without tuning, it runs very lean with way too advanced timing. I could only get barely 5 psi, used an air to water intercooler in place of the HKS intercooler and ran a small radiator in front of the engine radiator and a pump from a mustang cobra. My 0 to 60 was around 5.2 seconds, never really did any real testing to see how much faster it was but it didn't feel much faster. Again, only 5 psi is not going to accomplish much as superchargers suck up power just to run them. I had constant issues with the belt squeaking after 200 miles, from idle to about 2200 rpm, drove me crazy. Also the transmission started slipping under part throttle boost when shifting from 2nd to 3rd after about 1000 miles. Zero support from HKS or anyone else,I gave up and it sits on the garage floor to this day. Transmission is OK once I went back to no boost.
What are you going to do with this setup btw? Probably best to sell it all as one whole unit.I could only get barely 5 psi, used an air to water intercooler in place of the HKS intercooler and ran a small radiator in front of the engine radiator and a pump from a mustang cobra.
Big thanks for posting this. Wonder if 'Giovanni' posts here anytime.Check out The Smoking Tire's new One Take review of Giovanni's HKS Supercharged Rav4 - They didn't have much good to say but I give props for putting his heart and soul into his build. It should be pretty quick regardless of the "elephant" sounds. LOL
