only for the g sedan, the g coupe's ECU is already on the market.

The G sedan has a variable capacity muffler. Single inlet, dual outlet. The first outlet is always open, the second outlet is valved to open at approximately 3800 rpm. This produces max torque down low with freeer flowing for high hp up top.

They don't know what the final numbers will be. The automatic sedan saw >10 hp IIRC. However, it appears the 6mt sedan is tuned a little more aggressively and they lost power on the first try.

I don't know how it will affect performance, but those answers should be available within a week or so. I am not at the purchasing stage so I haven't got all the facts yet. Still researching my goals for the car.

 

I replaced the center section of the exhaust (huge resonator/cat combo unit that weighed about 50-60 pounds) with the coupe center section ( about 15 pounds) and that made a huge difference in sound and power.

 

What discs are they using in the fmu??? I am assuming they are 10:1 . I wonder if switching to 8:1 discs would solve the richness problem ......maybe a Vortech tech or vendor can answer this.

 

I'll ask about the discs. Earlier I had posted that the shop had used a laptop to do tuning. Turns out they were tuning the piggyback ECU chip and not the FMU itself. But the bottom line is that fine-grained tuning is possible.

This morning I [finally!!] picked up the car and had the chance to drive it around. My first two reactions were: (1) it's not as loud as I thought it would be--it's audible but not obnoxious by any stretch of the imagination; (2) it is faster than I expected. Redline comes up shockingly fast in first gear. In fact, the first time I really gunned it I had bounced off of the rev limiter before I knew what happened. Gotta be careful

How audible is the BOV in the cabin, I know it's purely subjective, but I'm curious.

 

BOV is audible as a hiss--especially if you rev the car up and coast to slow down. If you are trying to drive "quietly" you can shift early and almost not hear the BOV at all.

If you're getting on the gas, you can hear the BOV--but who cares in those cases, really. The car doesn't seem any louder at WOT than it did with my Injen CAI, to be honest.

so are you pleased with the results? After seeing/hearing your car it made me want one. The maxima might be getting retired sooner than expected.

any video clips soon...hehe =)

 

In fact I think I might post one up tonight...that is if we-todd-did-racing site stays up.

 

OOOOOHHHH YEAAAAHHHH.

OK I have a 1:30 clip of Steve's car but I can't get a host for it. When I captured it was 50megs. If someone will host it for me I would appreciate it.

 

Thanx sound like it is relatively stealthy at low throttle.
Just an FYI, I read on another forum that the SQ trim should not be cold started below 32F. Since the SQ gear tolerances are so tight lockup at a very cold start is possible. I don't know how 100% true this is, but there was a significant Vortech Forum thread on the subject via the Superchargers _online site. You may want them to clarify for you. It doesn't concern me in Nor Cal, but it could be a concern in NC.

 

I can host it. I sent you a PM with upload instructions--or you can call me at the number I provided.

--Steve

 

I keep my car in the garage at all times so it's not below 32F very often if at all--but I'll investigate this. I would have thought that sharing the oil with the engine would make cold starts less of a problem than with the ATI unit, but I'm hopelessly uninformed when it comes to this sort of stuff.

--Steve

 

The supposed issue was just at cold start. once running, the oil would definately quickley warm the gear case. tHe thread was fro guy whos 4x4 (up north somewere) with and SQ trim locked up on him . Vortech replaced his unit free of charge, but warned that they would not replace it second time.

 

old link , but this is were it came up...

Here's a short shot of video footage from outside the car. It sounds much louder outside the car than it does inside the car, so I'll need to take some more video footage to show that.

It has an INTERESTING sound at idle.

 

You really have to hear it inside the car (or at least with the hood down). I'll take some more video footage.

--Steve

 

One thing that I wanted to mention was the car was somewhat cold so the idle was a little higher than normal warm idle speed. This thing sounds so sweet in person.
