Turbo/Supercharging Your FRS

[dabocx]

Im looking for around 300whp. So hopefully someone can bust a aftercooled supercharger setup out.

There should could be a whole lot of busting going on lol

This car is really going to force the aftermarket to thoroughly investigate GDI fuel injection systems and how to tune them. It is already easily done in Korea with the 2.4GDI that we find in the Kia and Hyundai cars, 8psi seems to work perfectly with stock fuel systems and exhausts and power gains are high

I hear the biggest potential for performance is direct injection with alcohol fuels 12.5 CR would be good for a ton of boost in that case.

Probably very true

Tradewind goes hunting for the unobtainable high flow DI injectors to suit this engine lol

I think it works best when you use the port injection for the gasoline and the direct injection for as high of an ethanol/methanol concentration as you can get. The gasoline isn't going to provide much evaporative cooling, it's mainly there for the heat of combustion, while the alcohol is for cooling the charge down. That combination gets the best antiknock characteristic for a given "blend" of fuel. When you spray too much alcohol in via the port injectors I think a problem is that some of it might not evaporate and that's extra bad for combustion efficiency. Allch Chcar is doing E85 conversion I think

While 200 is a good starting point, I would definitely love to go this route at some point. I don't really want to do anything crazy. Having that little bit extra is always nice though and maintaining everyday drivability and practicality is a plus. That being said, I'd like to see around 250whp in the end. I've made do with much less and this will be enough for what I have intended for it.

You know what, I completely agree, till I get a taste of boost on that vehicle then I think well let's see what I can do just to add a little bit more... Nothing crazy... Then wow that was nice I can really feel that, ok let's try this... Before you know it you 700+whp and still craving more... Then you become a junky.... Like me lol all starts out just fun and reliable

Oh it's so true. I really think I'd enjoy this car very much in the 300whp range but 250 whp in a car of this size and layout should still be a lot of fun to toss around. 250whp is my NA goal.

I'd planned to wait on a FI setup after seeing the product from the factory.

oh it is a very slippery slope, especially when 'more' is simply a bump in boost.

Ive already had driving experiences in numerous high power boosted cars including an mkiv , r34 and others. Yes it is fun and the power is addicting. But, when we build a car, we build it with an objective/goal in mind. Some may be big power, show car, drag car, autox, time attack etc. My goal is different. Mine doesnt require anything ridiculous.

Lol I agree completely, but there's always room for improvement

E85 convertion is interesting. This Ferrari FF got E85 conversion and now makes 875 PS. No forced induction!

Everday car and fun weekend car. Go back to the shop in Vegas for moar of this! [u2b]Uj_EoX0Ruus[/u2b] Yes the ground is wet in some of the footage. Notic the black S14.5 rockin 18x11 VSKFs....Bone stock KA24DE. Even stock exhaust=less than 150hp. Don't need much to go out and play.

^^From the event back in December. Every year. I feel like just having a fun car with a bit extra OOMMFFFFFPPHH!!! would be perfect in a car this size and weight. Suspension work, knuckles, diff, wheels, seats, a bit more power would be perfect. I saw the car made like 170whp on a dyno. If I can get to 200whp N/A with mild work then I might not care to boost. I don't know how realistic that number is though since I've never tuned N/A motors before.

[Clorus]

generally i'm rather conservative and won't go beyond a remap.

however, i'm curious on how much forced induction would cost for this car. let's say minimum 60-75 additional hp

what do you think would be the average price to fit such a supercharger? a turbocharger?
