Has anyone ever plotted out the Boost Curve for a stock Evo X FQ-400? I also wouldn't mind seeing the Power/Torque curves plotted either. Any reference to those would be interesting. I'm curious as to exactly how much the UK Mitsu Engineers are willing to push the boost across the RPM band.

 

Crazy, I happen to do a search today to see if anyone has posted the stock boost curve of an Evo X FQ400. I couldn't believe it. The number one hit on Google is my own post with no response almost a year to the day. Anyone?

 

I am guessing that the type of people that would by the FQ400 and the type of people that visit this forum are mutually exclusive

 

I think that is indeed the case. I have yet to see a single FQ400 owner on these forums actually, let alone posting up a dyno plot with boost and AFR values that are meaningfull.

It's just such a rare car and the fact that they don't make it available here in the States means chances are about one in a million you will ever get an answer. Then again people do get struck by lightning or win the lotto, you never know.

 

I bet there aren't a lot of FQ400 owners. 80,000 USD is a lot of jack for an Evolution, even as good a car as the FQ400 is.

Though if I *had* $80k for a car...yeah, *I'd* be dumb enough to buy one and ship it over from the UK.

 

80k is a bit pricey.

You can make a FQ 400 for a lot lot less. A COBB 400S kit, a Alcon big brake kit, and a few other mods; boom you have a FQ 400 more or less

 

Agreed. I sure would like to know how much boost the British Mitsubishi engineers are willing to run in that thing...with a warranty! I'm at around 400 hp now, but I'm hovering around 24 PSI. It would be nice to see if the 400 hp could be obtained with less boost.

Here's the parts list from AutoBlog with my comments . Based on the parts below, how much boost would you guess they are running to get 403 hp at 6500 RPM and 387lb-ft of torque at 3500 RPM?

High-flow fuel injectors (I was surprised this was necessary)
New turbo with low friction bearings (Is it the same dimensions as the USDM Stock?)
High temperature turbine that Mitsubishi insists will keep turbo lag at bay (General goodness for longevity)
New intercooler (Makes sense)
A new ECU works its binary magic (Can't touch Tephra )
Three-inch stainless steel exhaust (That's easy)

 

Just remember a FQ400 is at the flywheel NOT the wheels.

Basically any well tuned bolt-on Evo 10 is a FQ400.

That said, I would LOVE to get my hands on a FQ400 ROM.

 

I bet you do .. how much are you willing to pay ??

 

Just curious if anyone has found any more information about the FQ400 factory tune/boost curve?

I'm also studying various tunes and quite interested in how they tune for longevity.

 

any one try lancerregister.com?

 

the last one on there was dyno d and found to be well short of 400 at the crank, it made 340

 

How much does the 3 year warranty cost in the aftermarket?

 

Definitely not 40k. You can re-build you complete motor ~ 3 times for that amount.

 

it depends on the dyno plus thats right on point if it dynos 340whp. thats only 15% loss from flywheel to wheel.
