Hi Steffen,

Great to finally see some real figures behind all of that hard work. :thumbsup:

I would question the drivetrain loss that has been assumed - 25% would be really on the high side.

Of course, without engine dyno figures it is always an approximation to establish the crank HP, but I would have thought something between 10-15% would have been more appropriate.

Enjoy all of those extra ponies !

Cheers,

Mike S

Just turned 2? Awesome work for a toddler

Can 'we' see the car in Wiesbaden/Giessen this weekend ??

Stefan, it wasn't meant -as for 'posing' power competitions ! those guys just understand more if you talking 'fuel talks' as your wife or neighbours... . So it is allways good to compare experien

Thanks for your comments. It's truly amazing how much energy the car has now. I hardly need to step on the pedal, It just gallops away with such a ease and effortlessness.

I am sure you agree that it is very hard to get true readings on a turbo engine as there are so many variables like ambient air temperatures, engine bay temps as you test etc.

The device Steffen uses is not capable of reading the rpms and therefore also not the torque on 4 cyl Esprits.

I am sure when we test again at. let's say 15°C outside temp, we are clearly over 500 hp.

Don't really know if dyno figures are any preciser ??

How have you always gotten your numbers on engine performance ?

Steffen's device is attached to the rear wheel and calculates the HP from there. At least this is a reading taken from a realistic scenario as you simply test drive the car to get your figures

Hey Stefen,

My power figures have always come from a rolling road dyno - again, measuring the wheel HP. At the end of the day, this is the real power that is propelling the car and therefore the most important figure.

The first dyno plot I had on my GT1 replica showed 375whp - which we equated to approx. 430hp at the crank.

Your huge jump in power output must make that baby really fly. I still want to see your car in the flesh sometime soon ! :sorcerer:

Cheers,

Mike S

Mike, you are absolutely right. Wheel HP is what we should be after because this is what you feel when you drive.

And I also agree that the drive train loss figure is questionable, At least it feels 400ish, for sure

I have a seasonal plate which ends at the end of october, so there is a slight chance for a visit.

If not, next spring for sure. You ought to drive her and get hooked, too rambo.gif

Excellent, you've got to get that framed!

Great work!! Going back to the breather again, so are you now feeding the oiley air back through the engine? I know this is as the original way to do it but to my mind its really not a good idea. Depending on how hot the engine is the amount of oil going into the combustion will be different. I also believe oil lowers your octane rating and increases the chance of pinking as well as premature detonation something even more common on a turbo engine. On my car I am planning to use a oil catch tank. I would think it s even more important for your highly tuned application?

All the best

Thanks for your positive comments on my car. Yes we do now feed the oil back in the original way. I am aware that this is not the optimum and agree with you that a seperate oil catch tank is probably the cleanest solution.

If I would still have a 2.2 l engine, I think it would make a difference but with the 2.6 l closed deck design, which uses up to 3l of oil over 1000 km this is not really falling into account.

Once you have your solution in place give me a shout.

Stefan

:unworthy: AMAZING !

Hans, I am sorry

I have overlooked your comment.

Thanks cheers.gif (Leffe brun, haha)

Let's see if we finally can meet before season's end as I am not too far from your neck of the woods

How about a nice cool saturday in October?smoke.gif

3L every 1000km ?!

With lets say 6-7L within the fully (oilcooled) system, you will have "new oil" at least every time you use the car. So this means only regular changes of the filter element ? :question:

This is max consumption when I really push her hard.

I don't think this is alarming and I don't change the oil filter every time I add oil

The engine is so robust now and with the oil scraper baffles on the crank I have no worries at allcoffee.gif

did'nt meant to change the filter every time ..just 'exclusevly' based on normal timeline -as the oil is regularly changed via the 'consumption refill' anyway :rolleyes:

At last, I have finally found a company that is caspable and willing to dyno my car properly. :animier:

They develop, manufacture and sell their dynos to tuning firms exclusively. Normally they do not accept end user requests for dynoing.

But the owner likes the Esprit so much that he invited my to a session, using their latest development.

Here is a link to GRIP, a german online car magazine which uses this dyno on various plus 700 hp super cars.

My Esprit will be used in another promo video of the company.

Feeling very lucky, indeed

I shall post my results here immediately after I have the readout.

Stay tuned

Cheers

Hi Stefan,

Nice work on getting all that power from a 4 banger!!

I am thinking about getting an Esprit for restoration and would also like to uprate the engine (although not with quite so much power :blink: )

I am a british person living in Germany (Munich) and everyone I spoke to said no no, it will never get a TÜV. How did you get all the modifications past the TÜV? My german isn't very good so any answers from Internet searches have been difficult. Any advice would be greatly welcomed.

Thanks

Nic.

Since the Esprit is a rather exotic model amongst all the registered super car models here in Germany, the TÜV can't really verify if your car is modified or not. Lotus has not even required about a so called "Fahrzeugchlüssel" ( model key code ) when applying for a ABE ( Type approval ) here in Germany

The TÜV has generally nothing to compare your car with due to the rarity of the model.

One could try to have all engine mods blessed by the TÜV but this could take ages here in Germany, if at all. Besides there are TÜV sections which are more donnish than others.

I just had the problem of getting my Sport 350 magnesium wheels certified for the S4. They are larger than the original rims. In conjunction with my chosen tyre sizes the TÜV Hessen in Wiesbaden did not want to to it.

But the TÜV Saarland had no problem as long as I provided a certificate that my speedo is calibrated to compensate for the now larger wheel diameter.

It all boils down to the TÜV inspector thas sees your car.

As long as all the specs listed in your "Fahrzeugschein" (vehicle registration document) are verifiable, you get your TÜV and I have never seen a TÜV office that has dynoed a car just to see whether it has the HP listed or not. Especially no Esprit.

This car is, by numbers alone, a closed book to them.

Hope this helped

Stefan

Absolutely right Günter

Concentrate on the "inner values" when you tune your Esprit, as the outside is spectacular enough :scooter:

And besides, I guess all of us here are far away from pubescent hot hatch teenagers :lol:

Indeed my boy racer days are long gone. The plan is to restore an S3, fit the S1 bumpers and rear lights and that will be it as far as the exterior. I like the classic look of the earlier cars but with the later underpinnings. Therefore, upgraded suspension, bigger brakes and a normally aspirated engine with fuel injection. Should keep it sweet looking but able to play with the Porsches on the Autobahn...up to a point anyway...I was playing with some wheel configurations too and curiously the Ford RS four spoke wheels seem to fit the car quite nicely.

But thats a long way in the future.....

If you have a G car in mind to tune, it's even easier. If you are lucky you can obtain a H plaque which is reserved for historic cars, older than 25 years I believe

to be exactly, for a German 'historic registration' it needs at least 30 years of age [date of first registration -of the car, not the model version] ...and you can only use additional tuning parts available in this time, legalized in the market for that car within the 30 years of use.

For real value keep it as original as possible, even if it means some signs of 'aging' ... contact *Classic-Data* for references and insurances and so on..

Thanks for the info Günter. The car I had in mind is from 1986 so the H plate (at the moment anyway) is irrelevant. Also the car is apparently in a really bad state and the interior has been badly "butchered" with Ford RS seats etc. It will never be original anyway.

Also, what is the purpose of an H plate? does it increase the value of the car for example?

more value

...as it means it is 'restored' at least to an good level, or mostly original without silly 'modifications' -plus : it is cheaper on the running cost (taxes, insurances) ..with no general mileage or 'term of use' limiting the usability. Bonus -you're allowed to drive in the regional 'emission control areas' in big city centers !!

On the *red-letters registration* (several cars in a collection run variable on one number-plate) you are normally (at least this what the law sais..) allowed only to use the car for demonstration, testing and car shows. What means you can't drive it on Holiday from Germany toward all across Europe. But the red-plate is now only available for collectors, with 'dealer-plates' slightly equal to this (same red lettering on the plate).
