Maybe it is drivers but they’ll never say so…I know of one 255 Cup that had an oil pump fail…and he did not over rev his engine…I have the Circuitworx Oil Pump Gears installed along with the upgraded eibach valve springs my motor…I left the factory rev limiter…

I’ve been following the Elise-Talk forum a bit and am wondering - on what kind of fuel are they running the Bemani cars in the US?
In anycase, driver’s ability will always be the limiting factor in things like this - I’ve seen enough times to see Exige-S or 240R’s fair better on the race track than Bemani’s, but have also seen the opposite - this isn’t to say one is quicker than the other as at the end of the day, it’s all about the driver on the track. Having made my own share of experiences, I can say with absolute certainty, all else being equal, a Bemani Exige is quicker than the Lotus supercharged variants. If you’ve seen something else, it’s either because the cars aren’t performing as they should (climate, weather?), or the other cars you’re comparing them to have been modified, driver’s ability etc.
Yep, Driver skill is by far the biggest variable.
My mate had a standard Elise S1 with 118bhp and was lapping the ass out of everyone at a track day last year (inc me in my 190bhp Exige). Decent suspension setup, tyres and brakes make more of a difference IMHO than bolting on another 75bhp.
Here in Ca. we run 91oct on the street or 100oct at the track unlead…at least that’s what we at www.moremonkey.com run

Woah, 91oct is quite low. We’re adviced to use 98oct at the absolute minimum overhere, preferably 100oct…
Dont forget all you need is a lardy passenger and the performance advantage would be gone

I think direct comparisons of octane between the USA & Europe are inaccurate. In Europe we measure octane in “Ron”, & in the USA they use “Mon” - I think - can anyone be more specific, please?
Okey, dokey, now found this with a conversion calculator Clicky
The only Bemani cars I’ve seen were at the track and I’d bet they were runing 100oct race gas…as I said don’t belive every dyno graph you see…all of these guys post very optimistic numbers…They all go for that cold engine best dyno run.
as I said don’t belive every dyno graph you see…all of these guys post very optimistic numbers.
You seem to assiduosly assert this � and it is a pretty serious accusation � but where is your evidence in relation to Bemani?
From what I’ve been told, Bemani played down the figures to avoid complications in getting it road-legal in Switzerland.
My dealer tells me that all the Bemanis they’ve measured have more than the official figure and most are iro 275bhp.

Can you post a real dyno chart and not some power point presentation…you know a chart that shows A/F ratios and boost levels ? I have never seen one for Bemani that looks the real deal…at six psi. they’re not anything close to a real 275…and if so could they do a number of back to back runs showing the same numbers +or-5hp ? real dyno charts…

Well, obviously there are people that have (and are not Bemani) if they claim to have seen figures around the 275 mark…
Also, who says/claims they’re getting anything close to 275 at six psi?
Well then how much boost are they making ? Do you own a Bemani car?..I know I’m making 13.3psi…my last dyno run was 290rhwp or 340bph before any street tuning…

Believe me, the Swiss authorities take things like power outputs of tuned cars seriously. If Bemani say that their S/C is putting out 263bhp (the maximum they can easily get road approved), then I doubt very much that they are exagerating. Furthermore, Bemani are a long-established and competent tuner who don’t need to make false claims.
In addition, as I already own a Bemani Exige, I can’t see how my Lotus dealer could benefit in any way from volunteering the info that all the ones they’ve had on the rolling road have shown significantly higher outputs if it were a falsehood. What benefit would he derive from it?
I still feel that, if you wish to dispute the published and officially documented output, it is up to you to provide evidence to the contrary to support such allegations
But don’t take it personally � whatever outputs these car have, they are fun!
It’s just that so many people will belive anything they’re told…all I’m saying is if Bemani or anyone makes a HP claim back it up with real world dyno sheets…Have you ever had your Bemani Lotus on an independent dyno just to see if you got what you paid for ?..I think not…nothing personal…
Dear Frank
First of all much respect for what you have done and I can understand your reluctance to believe anyone else but here is some info - Bemani dont run 6psi they run 0.55 bar = just under 8psi
When I picked up the car I received a dyno chart from my car and it produced over 270hp believe it or not but reputable tuners in Europe dont need to inflate their claims enough said
Cheers Jamie
Dear Jammie, as you know there has never been a true dyno sheet posted on any fourm with regards to the Bemani supercharger in the Exige or Elise…7.5psi now we know… If you can please post your old Bemani dyno sheet…Thanks
I know now that european tuners would never lie or inflate HP numbers in order to increase sales because that would be bad…
So let’s see the dam dyno sheets…
Cheers Frank
I also know now that the Swiss authorities are scaring all tuners around the globe…
I’m sure the Bemani conversion will have had to gain TUV approval to sell in Germany. If so, the power output will have been observed on a certified, calibrated bench dyno facility to with 2% of quoted power and 4% of quoted torque.
I dont understand why anyone would need to put their car on a dyno if its been properly converted and is running healthily.
Rolling road dynos all talk “cobblers”. I never trust any numbers I see quoted. Back to back comparisons possibly but never outright claims. So posting graphs up is a usually a waste of time unless you run the two cars on the same dyno on the same day and same conditions.
I’ve done power certs on several engine programs and the figures that some people subsequently claim to be flywheel power outputs back calculated from rolling road tests for stock cars is “very misleading”.
Also I’ve never believed any power output improvements for NA cars by chips tuners and I regularly enjoy taking the “michael” out of them at Autosport etc.
Before anyone says anything - yes I am a right “obnoxious person” sometimes.
Edited to be worded slightly more “pleasantly”
Bob
Agree entirely
Welcome to the obnoxious club - it’s getting crowed in here
With regard to the Bemani, I’d much rather hear feedback from owners who have forked out the cash. If they are happy with what they got then does it really matter whether a dyno sheet shows 250bhp or 270bhp? It sounds as though Jamie was very impressed with his Bemani conversion and no major problems with it since fittted.
All this dyno talk and ‘my bhp is bigger than your bhp’ is really beginning to sound dull. Frank, if the Bemani thing is bothering you so much and your having sleepless nights why don’t you either ring Bemani up or fly to Switzerland. I believe Bemani have converted over 100+ cars, how proven is your kit on the car which you own? and would you have the balls to admit on a forum like this that you’ve actually had issues in the past with your work of genius?
Bhp does not compensate for driving abiliy.
As to the size of my balls step over to www.moremonkey.com and take a look see…I would like to see the “100” supercharged Lotus list…I’d put money down on the fact that there are nowhere close to that many Bemani Lotus cars runnin around…as to my car it gets trashed through the canyons every weekend, you would call it a 250mi. hill climb and so far 24,000mi.
as I said I would just like to see a real dyno sheet not hearsay…it’s not a dick swinging contest…unless your into that kind of thing…
The funny thing about some guys that fork out the cash is that they will never admit they didn’t get what they paid for…
Bhp does not compensate for driving abiliy. …but it sure does help…why is it that so many assume the guy with the faster car doesn’t have skills
