Any updates on this build? I need my fix... ;-)

Well... I did some heat stressing at SoWS yesterday, and then proceeded to drive back through ACH in snow with bald RS3's.

New radiator prototype is in the car, and the car runs substantially cooler. When the fans kick in, the coolant drops 20F so fast that I can watch it in real time on our display....

I also drove a mildly tuned Fiesta ST and walked away rather impressed.

Anymore details on the radiator prototype? Is this a CSG future part or am I jumping the gun :-)

I see what you did there.

This is a part that we will be offering.

From our installation experience.... do the radiator before you put on the Supercharger, or you're in for a world of hurt later.

Okay, it's not THAT bad, but it certainly takes a lot more effort to install when you have a supercharger and piping in the way.

Yeah... it was a loaded question ;-)

Going to need pics now... LOL!

It's an AIM Solo DL, and it pulls data off of CAN. We're not using any aftermarket sensors; we don't need them yet. It's a full standalone datalogger with 3d accelerometers, and can log at up to 100hz, depending on the channel. It also works as a lap timer, predictive timer, etc.

It's a unit that we sell; they retail for $700.

What kind of aftermarket sensors can it take?

Any details on the JR kit running an e85 tune? With what you have solidified on the 91 tune (i.e. reliability, oem-like drive-ability), can we expect the same on an e85 tune? What hp/tq numbers can we expect?

I'll think there will be a good increase in hp/tq with a proper e85 tune with this kit. In addition, If you look at the speed the rotrex's is running at with the current JR set-up, there's a lot of room for growth even in that area...

Get the JR CARB Kit, run the base CARB tune, get a custom e85 tune and flip the "cruise control" switch when you want to run e85... or not when you just want the base map. You get the CARB sticker for us CA folks and an option of e85 power. Win win

(sorry long question reply ) perhaps @CSG Mike or David could respond too?

The cruise control 'flip feature' is nice, but I would like to have cruise control for strictly cruise control when I take trips, which in that case 91 isn't a big deal and when I am in my city I can run E85.

If I have it correctly, the JR kit is making roughly 280 WHP on 91 @ 10psi (give or take some breather exhaust mods) .... So would you say that with the JR kit running E85, we would be seeing 310-320 whp @ 10psi?

Can the flywheel and clutch take that? That is like 300 bhp (91) / 350 bhp (e85) at the crank roughly right?

What if I only wanted to have the JR kit @ 5 to 7 psi to keep it modest? THEN run E85 at 5-7 psi as well to keep it safe and under 300, at least at first. I like baby steps in these situations. My goal is to get the kit by end of May/ beginning of June.

I know people have stated that Tada San said this car could easily handle more power. Has it been confirmed how much added power can be handled? AVO Turbo world breaks down the FA20 being more solid than previous generation of subaru engines... which is encouraging when looking to boost the FA20...

If it wasn't for the fact that this FA20 motor is a completely different and modern design with an incredibly well made combustion chamber, we wouldn't even attempt to turbocharge these cars. But while many people associate it with the old EJ20 series motors from Subaru, there is absolutely no comparison besides the fact they are both boxer 4's made by Subaru. The entire design of the engine is different, especially the combustion chamber, which has been improved tremendously from anything previously made by Subaru. Not only is the engine a major step up, the ECU on this car is also a great design, reacting incredibly fast to knock and adjusting parameters to compensate. This helps increase the reliability of the turbocharged motor. As is well known by now, this is also a direct injection motor, helping both power and gas mileage. We've seen mpg figures as good as stock on the freeway, probably better than stock as we were not exactly sitting on cruise control during our testing!

We'll probably throw in a splash of 100 octane at the track, but the tune itself is still made for 91 octane.

I read JR's instructions regarding octane in their SC installation document (see below), and was wondering how/why you chose the octane you've noted.

It seemed unusual that JR stated categorically that 100 octane should be the go-to fuel at the track. Generally, I could understand it for W2W, TT, or the dedicated track rat, but I wonder if the average owner is prepared to go that route, separate from the issue of which octanes are actually available at any given track. Away from the track, how many drivers are prepared or able to put in a tank of 100 before going out for a fun day on the back roads?

All that aside, the kit looks very attractive on a bang-for-the-buck basis. Thanks for the detailed review.

"100 Octane (R+M/2) Unleaded Fuel - It is important to run fuel designed for abuse at the track. Even stock FA20 engines should run 100 Octane when at the racetrack to ensure consistency and reliability. The additive packages in 91 Octane fuel are designed for emissions and shelf life, while 100 Octane is designed for the high cylinder pressures and full load/throttle conditions you will experience on the racetrack. When at the track, we REQUIRE running a minimum of 50% 100 Octane fuel. We highly recommend running 75-100% 100 Octane when at the track."

------------------

In that same document, JR states that FI'd FA20 engines in the twins are going to encounter fuel starvation (and therefore potential catastrophic engine damage) when in high-G corners with the fuel level between 1/2 and 1/4 tank. They don't say whether this occurs in left-handers, right-handers, or in both.

I'm wondering if this has been your experience. If so, do you begin your runs with 1/2 tank or more and then make sure you come in before reaching 1/4 tank of fuel? Or have you successfully addressed the underlying problem - if you have, can you share your solution with us?

I know it's not "technically" the same kit, but on my Kraftwerks kit I'm at about 332whp on E85 @9psi, and I'm getting the slightest bit of clutch slip at the top at WOT. Time will tell if it decides to slip further at that power level
