Allan - thinking about making the leap to one of them? lucky!

 

1/4 mile times and especially trap speed would be much more telling than 0-60 because of lack of traction in the first two gears. Sometimes the same car with twice the horsepower does not show better times until over 60mph.

 

I am a new member here. Just some opinions. I understand 0-60 is not the most important gauge of a car's performance, but it is important, and these days we see cars with 0-60 times that are unimaginable back when I was in high school. (which was only 15yrs ago). I remember reading an article about 5 second club, now I guess it is sub 3.5 second club.

Speaking of lack of traction. If the forcefed kit is so powerful when turbo kicks in, shouldn't the user also size up the width of his or her tires? Also, one can practice launch until the point that traction is controlled?

In my opinion, 0-60 performance has a lot to do with torque curve. How much time past until you reach the sweet zone. Therefore I see many 400whp Elise doing mid 3 sec runs 0-60, because a lot of them are Honda engine with turbo, and precious time lost before rpm reach the sweet zone and then sudden acceleration, and in Lotus we do need a gear change, unlike corvette.

so one guy downstair said, the corvette ZR1 0-100 time is amazingly yikes, yeah the ZR1 reach 60 in 1st gear and 2nd gear gets you past 100, while other performance cars take 3 gears to do that.

I do agree car with more horse power shows after 60 or 100. That's why forcefed Elise post 8.8sec 0-100 runs, and tops out at 160mph, while my 240R takes 10 sec to reach 100, and tops out at 151. hey, 1mph over the official stat.

 

I agree with buz . The greater hp FF car would have a higher trap speed even if times were similar. 3rd gear and up would see greater acceleration. old school math said it took 30-35 more HP to achieve a 1mph gain in the 1/4. This is most likely due to drag after 100 mph.

 

FF car vs SC car. The usual scenerio is that SC car sprints faster, and after 60mph or so , the FF car starts to catch up'quickly' and pass the SC. Due to aerodynamic or powertrain drag needs hp to counter, and advantage for FF car. Then the SC start to lag behind, while the FF car just keep going and going.

However, most in this forum probably knows that driving FF car and SC car feels totally different. Expecially at the track where you really don't want sudden power delivery. Or maybe if you are good enough you can always keep your rpm at the sweet spot of FF car and have no trouble with it. I never tracked FF Exige, mine is SC, but even that I have problem as the tail tends to be happy and that troubles me.

 

Does the forcedfed 275 kit bolt-in and install the same way on an Exige as it does on an Elise? Or are the component mounting points and such different that some custom modifications to the install are required?

Forcedfed's website makes no mention of an Exige application on their website as they only refer to it as the "Lotus Elise Forcedfed 275 turbo kit". It's the same 2ZZ motor but I'm wondering there must be a reason why Forcefed does not market it on their website as an Elise/Exige 275 kit since the Exige has been out for quite a while now.

I suppose I could call them regarding these questions... but then I don't think I want anyone to convince me not to wait for my Exige S but instead pick up a na Exige now at a discount and throw a FF275 turbo kit on

 

Def, no, I don't think so. Too much money. Too much of a loss. Not enough of a desire either. But the numbers just go me wondering.

The only info I could find on the Exige S is 0 to 100mph in 9.98 second:

Because the basic car is so immensely strong but lightweight (935 kg, 2057 lbs), giving a power to weight ratio of 173.8 kW/tonne (233.2 hp/tonne, 236.4 PS/tonne), performance is phenomenal, with 100 km/h being reached from a standing start in 4.3 seconds (0 – 60 mph in 4.1 seconds) and 160 km/h (100 mph) being reached in 9.98 seconds (estimate) before topping out at 238 km/h (148 mph)

Does anyone have 0 to 100 times for a Force Fed Elise?

 

Does anyone have 0 to 100 times for a Force Fed Elise?

Right from their web site... 8.8 seconds

 

Right from their web site... 8.8 seconds

Haha. Thank you. I was too busying reading the articles.

Performance Specification:
Horsepower: 275
Torque: 200
0-60mph 4.0 seconds
0-100mph 8.8 seconds
1/4 mile 12.3 seconds @113mph
Top Speed 160+mph

So we're looking at 8.8 seconds versus 9.98.

Actually, they do mention the Exige:

The Exige S is street legal and the ForceFed 275 is not.

Is this correct?

Marc

 

street legal

IIRC, FF passes CA smog, but not the visual inspection -- technically not street legal.

Nope.

There are several folks here on ET that daily drive their FF275 Elises - and love them!

Very street legal.

EDIT: Oh... forgot about California... silly silly California -poke-

Damn! Forcedfed's 8.8 0-100mph is lightning quick! Actually, even the Exige S's 9.9 isn't too shabby. By comparison, the 997 Carrera S does it in 10.7 secs, my M5 (which I consider as the fastest car I've ever owned above 80mph) does 0-100mph in 9.4 seconds, and another straight-line whore I have in my stable, the RS4 does 0-100mph in 10.7 secs, and the brand-new 415hp 997 GT3 does it in 9.2 seconds. So it looks like an FI'd 2ZZ motor in an Elise/Exige can now hang with some serious heavy hitters on the straights... then of course pass them on the turns! :coolnana:

...except the C6 Z06 which can do 0-100 in 7.9 secs. Yikes!

 

You just made me more proud of my Exige S. own the Carrera S, nearly as good as M5, smashed RS4, and barely hang in there with GT3. Well, but Elise FF is the way to go, the chassis weight is 100kg less than Exige S. That means it corners even easier.
Corvette, that's a different monster. 1st gear all the way to 60mph, and 2nd gear pass 100mph........yikes.

 

FYI: My computer modeling of the TriPoint supercharger kit places it's 0-100 run at 9.3 seconds.

...except the C6 Z06 which can do 0-100 in 7.9 secs. Yikes!

Yeah, but don't you only have to shift once?

 

depends where you live if it is street legal. Here in Fl no emmissions which is great for turbo cars like my 90 eclipse. cat came right out. Even in NY there are plenty of places to get an emmissions sticker without ever going to a shop if you get my drift. The only drawback from the FF kit is if you want to retain your warrenty. Otherwise it would be like 2-3 days work to return it to stock for dealer service!

That's it. I don't care which of my children I have to sell, I'm getting a FF turbo.

Must...get...turbo...

I'm sorry but what is IIRC? In regards to the visual inspection, the FF turbo doesn't look to far from stock so it should be able to pass, right?

 

if i recall/remember correctly :up:

 

...except the C6 Z06 which can do 0-100 in 7.9 secs. Yikes!

Which is why that they have a 340hp kit. That's another 65 horsepower over the 275 kit!

 

Another question I'd like to pose in light of this FF275 vs Exige S comparo is which car do you think would be more reliable (warranty aside) for regular hard-running for those who track the car frequently? Also, aren't turbos more susceptible to significant power loss in hotter temps or when the car is run hard longer than a supercharger?

 

That's it. I don't care which of my children I have to sell, I'm getting a FF turbo.

That's the spirit! :clap:

Yeah, two issues there: heat soak and air density. Sit around for a while w/o airflow and the intercooler gets hot, losing efficiency and therefore power. The FF intercooler apparently has a puller fan, so maybe that helps?:shrug:

Forced induction motors make less power when it's hot. But you're looking at it the wrong way. The flip side is that when it's really cold, you make lots of power.:coolnana:

The Exige S has less boost than the FF kit and is tuned by experts. It will be more reliable on the track. But there's no reason why FF can't be tuned within 99% of where Lotus put it. There's nothing mystical going on -- at a certain engine load, you need a certain amount of fuel and a certain amount of spark. OEMs get it perfect, but good tuners can nail it, too.

You can always lower the boost on the FF kit if you want and run 100-110 octane gas for an added safety margin.

 

Did you guys just came from the moon? 0-100 in 9.9?! :wallbang:

Exige S
0-60 4.6
0-100 11.1
1/4 13.0

I dont think forcedfed will do 0-100 in 8.8, more like 9.2-9.5. 0-60 will be around 4.2.

 

Where is the FF275 intercooler located when installed. It is the same for both the Exige and Elise even with the "extra" room the Exige has.

Wherever the car is silly.

psst... they also have a 380 kit.
