Bemani tuning

I told Bruss to have Sinclairs check the bypass valve for proper operation they should be on the other side and not under the manifold, I told Sector to move them but that would take time and time is money…funny thing the first thing Jamincali asked me about was his lack of power in his Bemani car after I told him it was set right and he went from 3psi to 8psi…

For the money the Sinclairs kit is the way to go… [/quote]

Are you saying that it should be making more than 227 or that due to the design and install the best we can get is 227?

Thanks

It should make an honest 215 to the rear wheels…148tq.

Yep. New one supplied by Lotus, installed by the Lotus dealer. NOT cheap!

It has been having a winter sleep with less than 100 miles on the clock since then.

Seriously considering selling it in Spring before I break it again!

Now I’m not talkin about heat soaking of the air it’s the water in the chargecooler I’m talkin about, without cool air flowing over the heatexchanger you might as well have a tea bag ready because the water will be hot enough without cooling fans at low speeds

The heat in the water from the chargecooler is heated up by the heat of the charged-air. When the engine isn’t under load and car is idling, the charge air isn’t a factor and doesn’t add any significant heat to the water cycle - thus, no air-flow is required at idle, unless we are talking about idling the car until the point that heat becomes a factor with just about every other part on the car, regardless how many fans have kicked in at that point…

Tracks for testing…we have foulkin deserts with long steep grades…

You mean those canyons you call “driving roads” in your Youtube videos…

I’ve tested the same type of heatexchanger setup as the Komo-tec setup so you are wrong again, no effect on engine cooling…

I obviously can’t vouch for your car, but I do know that there have been observations of increased engine temps (loss of performance sometimes the effect) overhere by Komo-tec customers that have tracked their car hard on hot days.

I’ve driven just about every Komo-Tec variant outthere - from Exige-S tuned ones to their “Turbodrive” varients - how many have you driven to effectively know from experience and be in a position to claim to know anything about their kit or how well it works?

Why would I want my chargecooler mounted under the freakin headers

Under the headers?! Don’t know where you have any room there, but that’s not where I have my charge cooler sitting. Want to guess again?

As for keeping it “down there” - keep the center of gravity low and the water runs simple and as short as possible. Most of the heat also rises up btw, not down - and at the bottom, you may be even to use some of the air-flow from the ground etc. Not to mention to have it in a place that not only works for Exiges, but also Elises without larger modification required.

Name the amount and I’ll bet my charge air temps are far better than yours

That wouldn’t really be an apples to apples comparison though would it, not to mention the amount of factors that are just as important (pressure, ambient temps etc). Seriously, all that matters is that it works brilliant both at idle, on the road and on the track - and there are more than enough customers that can attest to that.

And just in case you’re blind - I already mentioned some temps.

he fins don’t direct air to the Bemani heatexchanger they allow for air to escape,

Not only that, but they also cause a lower pressure (negative pressure) by re-directing the air that travels under the car to suck the fresh air through the heatexchanger. The air traveling through the front-intake is more than enough to travel to both exchangers.

and yes the fans do reduce the high pressure in the crash structure…

Err, what?!

Charlie will have a tune for the 05-07 Bemani when this is all said and done You may want to contact him…

And void my warranty with Bemani and make it a non approved car under Swiss laws? No thanks.
Bemani sell the cars as they do (with the power they make) with full warranty - anything that would compromise longevity of the car is not something I am particularly fond of. Upping pressure without modding the engine block or tampering with a tune that was sold with the kit happens to be one of them.

To each their own though.

Well it seems that Swiss testers lie as do Bemani, in order to sell a Swiss product…

That is quite a serious claim to make.

Advanced cooling, on what planet ? The Pro-Alloy heatexchanger is advanced cooling with cooling fans mounted underneath… no fans on the Bemani heatexchanger no direct air flow like the Komo-tec heatexchanger…

Before the Exige I had an Opel Speedster (same chassis but with the 2.2 litre Ecotec GM N/A engine � also sold as the Vauxhall VX220 in the UK). Stuck in a nose-to-tail jam on the German autobahns on hot summer days after prolonged runs at 140+mph, I used to get concerned about the coolant temperature. The fan cuts in at 105�C and it did on several occasions. With the Bemani Exige,whatever the situation, I have not seen more than about 92�C. Now what the temperature at the intakes is under these conditions I couldn’t say � but then I don’t need max bhp when crawling on a grid-locked motorway (so it is totally irrelevant!) � and at speed the cooling is certainly not an issue.

It is all very well hurling abuse at the Swiss tuners and the Swiss auto press, but I don’t think you are doing yourself any favours. And please remember, it doesn’t matter if some US tuner gets a safe 500bhp out of the car, you cannot use it on the road in Switzerland. Not your problem, I know � but for those of us in Switzerland it is of paramount significance.

Speedy keep your head buried in the Swiss sand

Frank, I think I’ve explained enough times by now that it should slowly but surely be clear: Switzerland is severely regulated and you can’t do whatever you fancy, but only what a tuner has had approved by the authorities � and this is a costly and time-consuming business.

When I had my 147bhp Speedster, there was the option to buy the factory 2.0 litre 200bhp turbo model (which I didn’t want) or a Swiss S/C kit giving around 205bhp � but I couldn’t get good wheels, rubber, harness bar, brakes, etc., etc. as nothing had been approved. When Lotus offered a road-legal Cup Exige and Bemani offered an officially approved 263bhp S/C conversion it was like a dream come true for me.

Don’t ask me why I can run an Exige Cup on the road here and Cups are not street legal in the US, as I really can’t say. What I can say is that we have far more than I could have dared to hope for here with the Bemani S/C. What you do in the deserts of the US is of absolutely no consequence to me � and that is not because I have my head in the sand � on the contrary, I am very much in the real, stringently regulated and controlled, world

Keep up the good work lads - almost as much fun reading this, as the venom spat out by Special K

First off yes the water is heated by the charge air and it is also heated due to the fact that it is sitting next to a 450*f muffler with no air flow at low speeds…a foukin convection oven…so until higher air speeds are seen have your tea bags handy…

You are so right I misspoke, it’s the supercharger mounted under the headers the source of high charge temps tucked into the oven for pre heating

Yep it’s those canyons in 115*f anbient temps and little places like the Mojove desert…same as most OEM’s for high temp testing

No one has upped the pressure on these cars, all of the gains are due to tuning nothing more…

Warrentee ? give me a foukin break, what a baby… I’d be askin for a refund because you didn’t get what you paid for and that is a proper tune…you are not even close…
As far as passin any Komo-tec cars that’s next on the agenda…Their tune sucks also just ask Junks…

and yes your crash structure is compromised with the holes drilled into it…and high pressure is created when air is being forced into it as the car is moving…

Speedy K you have my sympathy for living in such a overly regulated country

Conceptics you

Speedy K you have my sympathy for living in such a overly regulated country

Why, thank you for that kind thought. Trouble is, it is so regulated that I risk terrible punishment if I drive my “useless” Bemsani at even a fraction of what it is built to do. And when I can only drive it slowly, the total lack of creature comforts makes little sense.

In fact, it is so bad here that I am seriously contemplating forgetting all about the “bare bones”, light is right, stripped-out Lotus philosophy. I may sell my Exige and 300ZX twin turbo to buy a Nissan GT-R next year (but a used one which has lost a tidy amount) That way I will have an all-year car (4wd), all the comforts I could want and great performance if I want to track it. Not the Lotus feeling, I know � but having played with one in the virtual world (GT5 prologue Demo), I can say that with all driver aids off it is very entertaining

If this statement evokes a diagnosis of insanity, so be it. Thing is, I don’t think the rest of europe is far behind switzerland in the ever-increasing oppression against drivers.

The GT-R sound like the right choise for you…I know if it were me I’d have a C4S coupe as my only car…

Fear not winter will be over soon I hear

Hell the only reason I said I would help with the tune was to piss Conceptics off

and now I’ve made new friends go figure

996 C4S in black with the sports exhaust and uprated suspension = winner

997 much better than 996.

Why would you choose 996 over 997 ?

What about those horibly ugly lights on 996 ?

Ex77

Dudes let’s stay on topic…

Frank,

Where is my 300bhp coming from ? Is there more to come from Sinclares kit ? Buying a 997 is the easy way out.

I want all the fun of the Exige and 300bhp. It seems at the moment Honda or Audi is the only way to go. I am reluctant to throw away a good new Toyota lump. If you can get more out of a Bemani kit do you think we can buy Bemani and get the necessary parts to upgrade from your side of the pond ? Is it just a tune plus some injectors ? Oh yes and fuel pump / regulators.

Summer is coming and there are plenty of big HP Supercars out there waiting to get their butts kicked.

Waiting for the big breakthrough.

Ex77

I think if you look at the the charge temprature with the non intercooled S/C car, there is an obvious thing to add, some form of charge cooling would be a good place to start after the S/C is installed, then smaller pulleys and finally a full engine build and custom tune.
If 300hp is reachable on a standard engine with a supercharger I hope to make it soon. Just need to get my base Gotham tune done and then start adding more parts again and keep check the AFR to make sure it is still within limits.

Hell there are a few things waiting in the wings as we speak…Now that Charlie is free to play with others ECU’s, I mean people that have done R$D to develope products and not just resell…

I’ve had a peek of some very nice soultions for the Elise/Exige and I’m told there’s more to come…

Remember the only thing that has held up the HP gains was the ECU and that problem is now over…

Let the ass kickin begin

I wonder how my ECU is doing? I believe it is with Charlie now, or he has had it already? Can’t wait to get the car back now, but I have at least another week to wait

Had dinner with Sinclairs last night, don’t dump the lump just yet…save your pennies

Now I’m even more excited, how long till I get my ECU back on my car

I gave Wayne a new set of 440cc injectors I believe for you and should see him and Charlie again tomorrow, I’m playin at the dyno again…

Bemani cars are back this Saturday with the proper fuel injection setup for final tuning…
