At the risk of de-"basing" this thread even more - the direction I see it taking (not that there's anything wrong with that) - don't you mean "you have a soft top (as in convertible) for Elle McPherson" and a hard....

And, shouldn't it be Megan Gale floats your car since this is an automobile forum?

Personally, I'm partial to Kate Hudson (continuing taking this thread into the gutter). That's what happens when you and your F-Type are snow-bound with, literally, mountains of snow blocking each and every path.

Oh, and if we're talking down-under, what's wrong with Naomi Watts?

 

 

You are correct sir! And I apologize for contributing to the digression.

Well, since we are digressing..and i started this thread god 'D#MN it, luckily you guys don't know who i am. I do choose cars, like I choose women...that sounds bad I know: let me explain. Sometimes, especially when i was a younger guy, i would go for the V8 R only. But with time, i have realized that some of the best women are sleepers...they are the V6's, that with a few mods, flourish into agile beasts. Actually that's not true at all...i have just become cheap.
With that being said....a pulley here or there, or a tuning chip might turn a v6 into a very fast machine: kind of like giving me a viagra.
So let's discuss getting more power out of the 6 base model...has anyone tried?

 

My final comment [re] your most recent post - and, no, while I have a V6S Coupe, I have no intentions of any performance mods; I love it just the way it is - as one gets older and presumably wiser one realizes that it's often not the biggest baddest fastest most expensive "x", or most [physically] gorgeous women/girl, etc.

It - life - is much much more deeply and meaningfully rewarding than that. Sometimes - oftentimes - or even all the times it's the simple things in life which are the most gratifying.

And with that I vow to end my contributions to this thread.

 

I know you are looking for someone that has actually done some tuning on their car...but here goes anyway. I've done a lot of research on the matter generically when I was tuning my 1.6L supercharged MINI (167hp increased to 230hp with a pulley and a tune) and more recently and specifically for the V6S. Issues identified:
1. The V6S engine is no different than base V6 except for the programming. There is no reason that the V6 couldn't be enhanced to provide the same performance or better with a tune from a reputable programmer. If somebody is asking $69.95 for OCBD module or other device, walk away. Eurocharged appears to know what they are doing and you might find others discussed elsewhwere on the F-Type forum that are reputable.
2. However, the sensation of power on the street does not come from hp. Power is only of value if you plan on maintaining the rpm within 500-1000 rpm of peak power. Your butt dynomometer rigisters torque. Notice that the V6S, though having 40 more horses than the base, only has 7 more lb-ft of torque. So, under normal driving conditions, the S doesn't feel much more powerful than the base.
3. Significant increase in torque can only be secured with additional boost. There are plenty of examples of V8S or R pulley/tunes because most tuners are thinking that V6 buyers would have bought a V8 if they were interested in more power. Not true for a variety of reasons: cost, weight, transmission.
4. The real question is whether the V6 can tolerate substantially more hp & torque. I and Foosh have pointed out a number of times that the base V6 already produces more power than the V8 on a per displacement basis and the V6 might not be able to handle the substantial increase of torque and power.
5. However, after researching the engine further, it appears the V8 and V6 are of similar design, critical components such as connecting rods are of similar design and dimension. I think we need to look at the stresses on individual pistons. The R is producing 69hp/63tq per cylinder. That equates to 414 hp and 378 lb-ft on a V6. As Adam Sandler would say: "not too shabby"

When my car arrives (July ?), I'll be initiating the following steps in sequence:
1. Run a dyno on the stock setup for baseline performance and to determine if there is sufficient (fuel dispensing) range in the injectors to accomodate the additional air (1.5 lb boost).
2.Install reduction pulley, and run dyno.
3. Work with one of the F-Type experienced tuners to optimize results on the dyno.

 

Amen to that.

 

I believe all Jags have "looked" better as coupes. But that doesn't mean it is better. I've been a roadster guy since my '59 TR3A in high school, I think an open sports car is more fun, weather not with standing. All of new ones I have recently seen are R coupes, mostly black.If I lived in Bay Area to Seattle I might think different.I tell people don't get a convertible if you are not going to put the roof down a lot. Ricky Jay do the "52" stay in your pocket when the roof is down?

 

Thanks for that very useful information! can't wait to see what you do.

 

The one thing you may not be taking into account is that the bore and stroke on the V8 and V6 are different.

 

I am indeed. If they were the same, the V6 would be a nominal 3.8L. The reason the V6 is producing more power/liter than the V8 is that it generates more boost as a result of a smaller SC pulley. In fact, most of the tuners are using an OEM V6 pulley to increase the boost on the V8. The undersized pulley for the V6 has to be aftermarket which I have already acquired from Mina Gallery.


The issue is whether the connecting rods, crank and rod/main bearings can handle the additional torque. I believe they can, as the main bearings and rod bearings seem to be similarly sized on both engines.

 

Thanks. That's good info.

I'm new to forced induction, since all my experience is with normal air breathers. I always used HP and torque/liter as the best indicator of power efficiency, but I can see where forced induction, with the ability to vary the boost, changes the equation a bit.

 

Exactly. Volumetric efficiency of forced induction systems can actually exceed 100%. The R engine isn't actually all that efficient since it makes ~600hp (project 7) with the SC. I was getting that much power from a Jack Roush built 5.3 liter naturally aspirated Ford engine back in the late eighties mostly accomplished with porting, mirror polishing and large radius turns in the induction system (intake manifold & heads). Displacement really isn't the limiting factor for power. Just a few years ago, naturally aspirated 3 liter formula one engines could generate over 720 hp (at 18000 rpm). The limiting factor truly is the ability of the engine design to withstand the wear and tear of the combustion and load parameters.

 

You're right. Impressive.

 

New guy here -----

I am considering ordering a 2016 base V6 ---- I note that that V6S only has a little bit more torque and I will not be tracking the car.

I have a 2015 Corvette (which I will keep) and am looking for the F type as a GT rather than a sports car.

I am a coupe guy --- maybe that is genetic since there seems to be such a definite split between convert and coupe guys ------

Thanks for all the good info
