Today two Bemani cars are going to the dyno to see what they will realy do once they get their heads out of the Swiss sand
An 05 Elise and 06 Exige are being tuned by Monkeys…stay tuned [oh dear I hope so ]
Can’t wait to see the results, you doing before and afters?
Ok Stock Bemani 224rwhp and 149tq. so far 239rwhp and 163tq a nice gain but there’s more to be had…The Bemani ass holes screw with the in tank fuel pump regulator and are putting out 80psi with 310cc injectors… Fuel pressure should be 47psi with 550cc injectors for the proper tune… So we ether find a proper inline regulator or the pump has to be changed back to stock…a major pain in the ass…
I feel bad for the guys that got suckered into the Bemani bull [censored], freakin bone head way to setup the car…
We’ll get back to tuning after the fuel injection is straightened out…
The standard Bemani tuning has to comply with Swiss vehicle testing regulations. Under these regulations, they are not supposed exceed 263bhp (but, according to rolling road tests done by external testers, the majority are around the 270bhp region � which they can just about get away with � explained by individual variation).
All I can say is that the Bemani system with its advanced cooling system simply works � under all conditions! (My engine failure was caused merely by driver error and would have happened irrespective of the state of tune).
Personally, living in Europe, I would not want a US-based high state of tune and, living in Switzerland, could not get it approved anyway! Conversely, if I was in the USA, I would prefer a reputable US tuner to a European one � mainly because of the potentially simpler sorting of any warranty issues.
I don’t know what claim are made by those selling the Bemani kit in the USA, but it was conceived to comply with the Swiss regulations. for the USA, I am happy to concede that there may be more suitable (but not necessarily better � all things considered) solutions
Hi Speedy K,
Nice to see your postying again. What did you decided to do about youir blown engine ? Do you have a new one at the outrageous price or did you go another route or even give up ?
I am considering a Bemani also now. If I had the contacts and knowledge I would love to be able to do what Ronin is doing but the reality is I just want to drive it ! For this reason the Bemani seems tried and tested and a steady 275+/- hp.

Bemani’s way of tuning is a foukin joke they have no idea as to what they are doing…One car had two different size injectors…The fuel maps in the tune are ridiculous, totally maxed out after 6,0000rpm, a total timing advance of 16* when it should be 27*…I’m waiting for the owners of these cars to install chargecooler temp gauges to see exactly what the intake temps are…This is the shitiest tuning setup I’ve seen since the Hass Turbo…
.Bemani couldn’t tuna fish let alone a Lotus…
Both of these cars were tuned by Bemani themself not a US tuner…
Now the good news is that the cars can be tuned…so far 200+tq and 270rwhp
There is no ragged edge in a proper tune, just the right way to do it…
Can’t wait untill the proper fuel pumps are installed and we do it all over again the right way

If the car had different size injectors, it probably had them before as the injectors is something that’s not included in the kit. Who are you trying to fool?

I have one - what do you want to know?
Hi Frank,
What is your suggestion for my problem. I am in the U.K. and looking for more “reliable” power for my Exige. Can only use U.K. pump fuel 99RON.
Must be reliable, must be fitable by someone in U.K. and give me no problems.
Bermani has a lot of satisfied customers in U.K. but if I can get better why not.
This is your chance, in words of one syllable please, to address your admiring audience in U.K. (and beyond in Euroland)
Which is the way to go Frank ?
Is it not Holiday in USA today ?
Thanks

Well it seems that Swiss testers lie as do Bemani, in order to sell a Swiss product…
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…
Bemani sell Bemani in the US and they are installed by one trained Bemani installer…
Speedy keep your head buried in the Swiss sand
I was asked to help out by the owners of the cars and I am not selling crap or taking a dime…they are having the ECU’s tuned and flashed by Charlie and the wrenching done by the guys at Beverly Hills Lotus…
.Bemani couldn’t tuna fish let alone a Lotus…
Reminded me of the line ‘you can tune a piano but you can’t tuna fish’…

Every day is Holiday in the US of A
Sorry two syllables …Sinclair’s call them…only 99ron :grin
There are other kits waiting in the wings as we speak now that Charlie is free to tune any Lotus car…
Frank,
What’s your take on the recent Dyno done on the Katana kit by Sinclaires? It seem to be somewhat down on the expected gain. (227 bhp instead of 240+)
Genuine interest here as I have some money buring a hole and the supercharged route is a calling.
Cheers

Sorry dude it’s you Bemani customers who are the fools…
…so can you fool a fool ?
Do you know what size injectors are in your car, have you pulled them to see ? Why the foulk would I lie, I’m helping a friend not a customer…
What are your intake charge temps on the dyno after 30 pulls with a 36" fan blowing on to the nose of the car…?
Just the facts Jack…

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…
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…
Of course there’s direct air-flow. The air flow is resulted by the fins located on the under side of the car. Result is a constant serge of cool air to the underside of the car while driving.
Komo-Tec’s heatexchanger may get a lot of air by being right at the front, but it certainly doesn’t help the standard exchanger located just below the top exits by feeding it with warmer air.

No one said you’re lying - you just happen to be pointing in the wrong direction in your outright criticism and I’m merely correcting it.
As I said, the injectors aren’t part of the kit - the Bemani kit and one of the reasons it’s allowed legal in Switzerland are for the few parts that are modified/replaced. That the cars use the standard injectors has been known for ages - it’s really nothing new. If the car you found had different injectors on it, doesn’t have much to do with the kit itself I’m afraid.
What are your intake charge temps on the dyno after 30 pulls with a 36" fan blowing on to the nose of the car…?
Never over 50.7�C. More in the range mid 40�C. (Yes, that’s air-intake temperature, after charge-cooler)

Ok when the car is idle there is zero air flow over the Bemani and Komo-tec, the Pro-Alloy kit has two fans mounted and the water never heat soaks…
The Komo-tec works better than the Bemani because it is in direct air flow when the car is in motion, I started with a similar setup…The Bemani setup loses it’s air flow as soon as the cooling fans kick in directing the air up and away from the heatexchanger…sorry just fact not fiction…a fool and his money are easily parted

Backtracking already a little?
Think you may also have to check your definition of heatsoak (and the causes). When the car is in idle, there’s no load on the engine, no charge-air being forced into the engine (other than to keep it idling). At these idling speeds, the air going into the engine isn’t significantly heated up by the supercharger so an air-flow to the exchanger for the intercooler isn’t necessary. It is when the engine is under load however, which is when it works at its best efficiency…
Not like in your solution (no pun intended) which has your charge-cooler located ontop of the engine, so perhaps continuesly cooling down again is beneficial. Or did you already decide to move it?

Lol, where do you get this stuff? You seriously think those small fans starv the heatexchanger at 50mph+ when the fins under the car guarantee a constant air flow to the heatexchanger? I can tell you - they don’t and the notion of them doing so is simply laughable, considering those fans are made for when the car isn’t in motion and heating up when there is no (or little) air-flow present.
As for the Komo-Tec solution being better - I trust we have a little more of both on tracks and road overhere and I can tell you from exerpience it isn’t, for the reasons noted above. If anything, the engines exchanger is running a lot less efficient as it’s blocked by the exchanger for the charger - the friction warming the airflow even further. It does have one advantage and that is no down-force loss, however.

Back tracking where ?
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
Tracks for testing…we have foulkin deserts with long steep grades…
I’ve tested the same type of heatexchanger setup as the Komo-tec setup so you are wrong again, no effect on engine cooling…no need to reposition my chargecooler…no heatsoak for me Why would I want my chargecooler mounted under the freakin headers Name the amount and I’ll bet my charge air temps are far better than yours
The fins don’t direct air to the Bemani heatexchanger they allow for air to escape, [intake is from the small holes cut into the safety crash structure, duh]…while the car is in motion…and yes the fans do reduce the high pressure in the crash structure…The cooling fans are set to turn off at 80mph at that point they become unnecessary
Charlie will have a tune for the 05-07 Bemani when this is all said and done You may want to contact him…
