More Mercury Motorsport Magic (Or Madness)


Recommended Posts

I want to give a very BIG thanks to the team at Mercury Motorsport for turning my GTR into something that is now simply amazing. The figures speak for themselves in the attached Dyno chart.

The chart shows pre tune 262 awkw and 465 awNm. Other than the Titanium Willall mid pipe and cat back system already installed, my car was dead stock. There was NO tune of any kind to support the Willall exhaust, So these figures are only slightly higher than a dead stock R35 GTR.

After Mercury installed their new 3.5" catted high flow dump pipes, a AAM Competition Air Intake system and the Cobb tune with their custom Dyno tune over the top, the results ramped up big time.

The acceleration has gone from brutal to totally savagely demonic!!!

As you can see in the chart my car now has 342.6 awkw and 625 awNm.

Not to mention the massive fattening out of both Kw's and Nm's throughout the entire rev range.

These are significant improvements, especially when you realise, that is an increase of 80.6 awkw and a wopping 159 awNm.

The guys at Mercury explained that, the percentage of drive train power losses does not stay constant when power increases, which makes sense.

This is interesting because even if I add NO extra Kw's or Nm's for further drive train losses and simply add the net at wheel power gains to the factory at crank specs of 357 Kw and 588 Nm, I now end up with 437 Kw and 747 Nm at the crank. WOW!

Due to the Titanium exhaust (largely) and air intake system (slightly), my car is approx 40Kg lighter than stock as well.

To say I am loving this car even more than I did before, is an understatement!

Anybody thinking of trading there 09 or 10 GTR in on a new 11, don't bother. For a quarter of the changeover price you can turn your existing GTR into a 2011 crusher. Unless of course they do the same?

I am so looking forward to my next encounter with the new Turbo Porsche. Just getting slightly ahead of them is now replaced with their total annihilation. Happy Days aheadrolleyes.gif

not sure why your car only made 262kw with light mods and others made 291kw stock std

Great result Kymbo.

In respect of the J-Rad post people should not compare raw dyno results of one dyno to another dyno, unless they know how that dyno typically reads for a specific model.

I would have expected around 300awkw on a dd dyno as guide using standard mode.

However, as the dyno is a dyno tool just focus on the before and after results from the same dyno for the changes to a specific car run under the same conditions.

In this case the relatively change is huge, with no loss anywhere, and verified on the road.... and a happy customer.

Do you know how much more boost was added?

p.s I'm blown away by just how good the standard 11 is on the road, after 1600kms in 4 days.

As bcl posted, dyno testing is best used as a before and after tool to assist in measuring gains. Absolute numbers are difficult to analyze. The track and drag strip are a better way of comparing cars measured on different dynos.

Kimbo, was great to meet you the other day. Look forward to catching up at the track soon ;)

Thanks Brian & Mark

Yeh, I am stoked!

And you are both right. It is the before and after on 'that' specific dyno that is relevant instead of trying to correlate one dyno's figures to another. I could have taken my car to some other tuner on the same day and on their Dyno got a 50 awkw different reading?

Anyway, bottom line is, on that dyno, that day the Mercury guys got a huge jump in power over the stock power output. That NET figure is what matters, when considering how it fits in with improved output relative to the factory claims.

Look forward to seeing both you guys again in the near future.

Kymbo

Oh Yeh!

Forgot to mention, The Turbo's now boost to 17 PSI in the 342.6 awkw mode!

The stock boost was 12 PSI.

The new 'mild' setting now only boosts to 10 PSI, yet interestingly still produces the 260 awkw as it did with the exhaust only. This I believe is due to the extra hardware?

So a standard GT-R only makes 260awkw dead stock? Jeez when you put it like that you kinda have to think about how it is such a dominant force when 260kw is only a pfc and 14psi from an RB26.

Hi J - Rad, what is pfc?

Glad to hear you got your beast!

Enjoy!

I wasn't trying to bring up a dyno debate. Just saying that its power figures weren't all that high, yet it still manages to be so good at doing everything. Had nothing to do with figures or anything. I have no idea how much a GT-R should make at the wheels. Was a mere observation that a 300kw R35 is alot quicker than a 300kw R32.

No problems; even though heavier it does have 46% more cubic capacity and 18 years of development over an R32.

The 11 will pull around 124mph trap speed at the strip, so it is very good stock. Also, people often look at just peak power, when average power is far more relevant, and how the torque is delivered.

On the 11 I'm seeing 15lb max boost on the boost gauge. I'm not sure if 12 pound is standard for the earlier model.

Cruising along at 2500rpm in 6th and onto the accelerator will see 15lb by 3000rpm. Factory spooling is pretty good, for what I believe is a non-billet compressor turbo.

As Mr Mizumo told us, the car (11) has more power than stated, and by seat of the pants I'd say he is correct. I'm going to take the car down wsid in a few weeks time, as I always see trap speed as a good indicative of power.

glad to see u've got your car back.

Would really love to see the monster myself.

I'll be there for the next meet up :D

enjoy the ride!!

Edit: the mods i have is pretty much the same as urs, beside the intake. mine is sitting at 328kw! that intake sure does make a big difference :D

Torque and response - and gearbox, is what's predominately behind it.

    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
