[Custom Twin-Chargecooler setup]

Hi Mark

Cool and Groovy result B)

Congrats.

Please report on any improvements over the old state when running.

Thanks for all your positive responses, guys

I am more than ever convinced that, as Alex said, a 4 pot CAN cut the mustard. One can feel almost special having "just a 4 cyl" on today's 12 cyl catwalk !

Spot on mate

As the boys need to do tome tidying up yet on the engine bay etc, the hatch is not on yet.

They took the chance to video it on it's first real test run.

I just love that perspective as it give you a real rush watching the road dissapear

[Project Sport 500]

Alright gang,

The wait is over.

Here are the first 2 videos of the car running !

It runs smooth as silk, no funny noises, but we needed to be carefull as everything is new.

I guess the hardest thing for me is that I now need to drive it 1500 km to break it in, taking it

easy and shift no higher than 3500 rpm.

What we noticed though on the first test runs was that even with no fine tuning yet the wheels have a tendency to spin

Looks like a differential lock is the next mod to do

First test run :

exhaust sound sample:

[New V8 exhaust]

This is what it looks like.

The company claims that it will produce aprox. + 15 HP

It's got 80 mm pipes all stainless steel.

Price: 1007.-

[New V8 exhaust]

Just got this in R & Bs latest news letter

Thought I share it with you as it sounds quite impressive

[Project Sport 500]

Patience, Patience

Don't want to terrorise you with the sound of a first start up of a brand new engine

Once the babe runs smoothly, I will have something for the spoiled ears of this esteemed audience

[Project Sport 500]

Spoke with Garry last night and he thinks Mike's turbo would be good for 600-700 HP.

But the lager turbo would need more time to spool up and therefore the drivability could suffer in lower RPMs

Well, we need to see first how the car performs with what we have and take it from there.

[Project Sport 500]

Don't tempt me Mike

I am very receptive to these things

I will have a word with Steffen and Garry and see what they think

Thanks for showing

Stefan

We know about this but how much the exhaust pipe needs to be adjusted can only be determined after some measurements once the car ran with

the one we have on it now.

I have no problem down from the Turbo. This is a 3" V Band exhaust

The bottleneck can only be the silencer and the end pipe.

We will see

[Project Sport 500]

Buddsy

As if you had smelled it. First start up is planned for tomorrow.

As I have promised I will post a sound sample and/or put a video in utube.

So hold your horses, matey

Stefan

[New Giugiaro Esprit?]

The yellow one is TOO busy.

Agree

If this yellow one would be the new Esprit I'd buy it instantly! Esprits need to be outrageous and good looking. This concept is all that.

Also agree, but they need to clean it up and make it less busy just as Rich stated.

Otherwise a very new and agressive look.

[Project Sport 500]

waether's fine (in fact great, been a loooooong time !) in Belgium Stefan, I'll take it out this evening on the trip to work

Having some night shift, so need to get some sleep during the day

btw Stefan : are you going to German's Lotus Club Season's opening meeting 1st of May ? I'll be there, guess bosbon as well

Hans

Sorry for moving you to NL. I have never really looked at your flag. Shame.

I am sure you enjoyed your ride out with the S4 while I was at home, grounded

Unfortunately I will not be able to come to LCD's season opening as my mother in law celebrates her 60th birthday on May 1st.

But I am sure we will meet during the season on the one or other occasion.

That looks ace, I've got to jump out of a plane at some point, I love adrenalin and can imagine that it's the ultimate buzz !

The air filter is a popular upgrade on many cars, nice to hear it makes the engine seem to rev more freely, I hate to see an engine suffocated on the way in or out.

Bibs,

Skydiving is a great sport and if you have the chance to make a Tandem Jump, grab it.

Check this out and tell Dave I sent you. http://flatfly.co.uk/xxx.htm

Great to hear you also like engines that can breath freely

[Project Sport 500]

Hey Hans

Bad weather in NL ? You should be out driving your Esprit

Yep, skydiving is the last legal drug Especially when you can boogie in paradise

As to the Pipercross : I just copied the above from their website to explain the way it works.

I have no data with both systems compared but my personal impression is that the car runs much more effortless in all RPM ranges.

Just like a breath of fresh air, one could say.

[Project Sport 500]

Is that a Pipercross Evolution filter?

Oh, and is that you jumping out of the back of the plane? If so, you're a lunatic!

Bibs, it's a Pipercross Viper induction system (info below)

How the Viper works

The technology used in the Pipercross Viper was first seen on the famous Lotus 340R, but soon became available for an ever increasing range of popular road cars.

Using 'velocity air force', each Viper air intake directs cold air directly into the engine. The cold air feed takes air from an area of cold, dense air straight into the Viper's inlet, swirling it through a unique Pipercross reverse-flow air filter contained within a carbon fibre heat shield, then into a ram pipe to increase the air pressure before feeding it into the induction system.

The carbon fibre heat shield protects the air charge from under bonnet heat keeping it cool -and therefore more dense -thus introducing more oxygen into the combustion mixture,giving increased power.

The reverse flow technology filter and 150mm ram pipe make use of the physical phenomenon of air tending to move towards surface area's, creating more air flow on the edge rather than in the centre of the inlet. The unique design of the filter cone and the inlet 'tune' the moving air flow to increase its speed and therefore its pressure maximising the laminar air flow into the engine, again resulting in increased power.

And Yes, that's me just outside the ramp of a C 130 Hercules over the Gulf of Acapulco.

We landed on the land strip you see below. Not much choice : Sharks on the left , Aligators on the right

But I guarantee you, there is no speed limit up there

Because a new engine needs a new sound, we have installed the new R&B central exhausts yesterday.

Can't wait to hear it. It will be covered by a V8 Type aluminium rear plate yet.

Hope to post a sound sample end of next week.

Cheers

Stefan

maybe a dumb question : why do you still use the original chargecooler pump ? Wouldn't it be better to replace it byan electric chargecooler pump ?

Hello Hans

Sorry for the late reply, but I had to retrieve this info from R & B

Here is what Steffen Brandt told me

1. Important for the cooling power is the surface area of your cooler in front and not neccessarily the pump as we have long distances in our cooling cycle

2. The mechanical pump works by engine rmps which is more efficient and produces no power loss. For example it delivers 12l/min at 3000 rpm and 15l/min at 7500 rpm

The electrical pumps work, but do not have any significant advantages ( according to his measurements when comparing both for performance )

He thinks the main reason why people have gone to electrical pumps is the price of the original spare part ( 1000

[Project Sport 500]

Back from Acapulco where I spend a marvelous time skydiving

As promised here is my post holiday upate

Today the engine was placed into the bay. Next step will be to modify the right bay wall to integrate

the Viper induction system.

More to come, so stay tuned.

Stefan

[Project Sport 500]

Hi everyone

Sorry for being behind schedule, but I am swamped with work.

The engine is almost complete and ready to go into the bay.

Maybe I should leave it out as it looks too juicy. ( always felt like this looking at Mike Sekinger's masterpieces )

This is going to be the last post until beginning of March as I will go on a longer trip.

Acapulco here we come

Cheers stefan

[A new age, and the end of white supremacy.]

Paul,

First I thought it was going to be a political manifest about the new US head honcho when I read the topic, but

to my surprise you only stand in line with all of the world's politicians, denying today, what they have said yesterday.

As this is common practise in today's world I suggest you pack away your scourge and enjoy your new toy.

Stefan

[Project Sport 500]

One step further, guys

Some other interesting mods had been done to the oil baffle shield.

As you can see, there are holes drilled into it alongside and then funnel shaped.

These holes let the oil flow back, which has been scraped off the crank.

Behind the scrapers you can see the oblong holes which dispose all the oil scraped off.

To make sure the oil can flow unrestrictedly, Steffen machined 2 more oblong holes into the oil pan.

[Project Sport 500]

Today's catch

[Project Sport 500]

Here's what I'd like to know.... how the hell is the magnetic base of your dial guage sticking to the aluminum block??? -- Edit... I see now.. you've got some angle iron attached to the side of the block there... VERY CLEVER! BTW... Very very very nice work! Those crank scrapers are a brilliant plan... what's the clearance to the crank?

Mark

Clearance is around 2/ 10th of a mm.

Nice progress Stefan.

Have those scrapers been proven? I'd worry about fractures developing along the fold line. Seen similar before and engines ruined as a result.

Dan

They are proven in Drag Race enginges, can't tell you the thicknesso of the sheet, but due to the additional folding on the sides, they are very strong.

Here are todays Pictures showing for once the axial side clearence adjustments and for the other the specialy designed intake cam.

As Steffen Brandt told me today, they are coming along nicely with their work so I hope we see pictures every other day.

Stefan

[Project Sport 500]

I want some!

What...even more madness ???
