Experieces in Racing an Europa

[Valerio Leone]

I still not understand why the Suisse do not want to give us some information!

[skwiz]

Hi Stefan,

Thank you anyway for your help!
This sounds weird, I don't understand why the Swiss don't want to help us..
Ideally we need a photo of the engine bay, but we could try to use the documents I collected so far.

Entry list Ollon Villars 1971.
Entry list St Ursanne 1971.
Official Results St Ursanne 1971.
Photo of the car in action at St Ursanne.
List of races the car has taken place untill 1974.
Photo of the car in 1973.
Catalogue with tech spec of the Swiss Lotus Dealer.

In case some of you want to proceed just ask me, I will email the documents.
I am undergoing to restore my R8 Gordini 1100 racecar period F.
I will be off from my Lotus for a while...
Ciao
Valerio.

Hi Valerio,

I have just removed the chassis yesterday (I'll post pictures on the french forum Asap) and I am interested in getting all those documents (you have my email already) as I will need to now what I will reassemble.
I just need to find the proper person to contact as my previous contact was not really helpfull...

[Valerio Leone]

I'm wondering if this car could be one of the one.

Hi there

I finally got an answer from Alfons Tresch, but he has no pictures or documents in his archive. He just said that both of them (Tresch and Bubeck) used almost completely standard cars. The only things changed were the camshaft (Albert) and carburettors (Dellorto). Pity!

Best regards

Stefan

ciao Stefan,

sorry to say, but why pity?

Were those cars Hemi engined? YES.

Have those cars two carburettors? YES. no matter the make since the appendix k allow us to change the make.

Were those cars competitive? YES. Look at the results.

The fact they were "standard" don't change the fact they were classified as Group 4 from FIA.

The real pity is that he don't have any picture.

Anyway, our French friend Skwiz is enquiring FIA for this configuration in order to proceed on request of official HTP.
He collected a nice Dossier with new photos and documents.
We will have the final response by end of June.

Good news, I'm curious on what the FIA's respons will be. If he gets the go-ahead we're finally out of the woods and we have a certain direction that we can take. Some very clear guidelines.

Hi all

Indeed valerio is right I sent it already although I didn't received the acknowledge receipt for my mail and today was the deadline for the June session, let's cross fingers !!

I have a gearbox question to all of you:

Whatever the decision, I will swap to 807 hemi and if I have to, I would register in TSRC for that. I have a R16TX to put in the car as soon as I rebuild (if I don't buy a 807 soon enough), but anyway I don't have the gearbox so I definitely need to buy one.
But I have no knowledge in that area (in the french forum I was basically told to look for models fitted in the same side of the engine as the lotus but that's all...). So...
First which type of gearbox would be allowed, either in TSRC of GTS 1600 (5 gears alowed ? which references ?).
Second which are the best/strongest gearboxes ? How to recognise a race gearbox and how to find one ? Etc...

Also in term of engine, I will certainly do it in two step, get an original one in the car, and latter strip it down and tune it for races with proper components. Do I have to look for 807 20 only (the ones of the r12g and r17g) of are there other option ?

Thank you for your help

Hi all,

Bad new has arrived from FFSA... They don't agree from the homologation of the Hemi in GTS 1600... (with international HTP).
Maybe you should try in you own countries !

Mecky the result is I will certainly go for TSRC, so we might race together some day 
How about wheel size for TSCR, what is the limit permitted and what do you advise to go for ?

I do really like the panasport from technical shop happy, but the guy is from japan...

Hi skwiz,

Do they give you any sort of explanation on top of this disagreeing?
I personally think that this is a shame.

Let us know!!

[Mecky]

Hi there,
wheel sizes are

front: 8x13
rear: 9x13.

[skwiz]

Hi skwiz,

Do they give you any sort of explanation on top of this disagreeing?
I personally think that this is a shame.

Let us know!!

Actually the biggest shame to me is the fact that as an answer to the 50 pages folder, they almost answerd "No." (actually one sentence with no explaination...  )

Mecky : Your rear wheels are twice as large as the original ones !! ^^ I understand why you have those wide wheel arches !

[Valerio Leone]

Well, this was the official answer of FFSA right?
What about FIA?
I don't think this is up to a National ASN to decide. The answer have to be provide by the international federation.
I wonder if FFSA now could accept the TSRC configuration...
 

[Valerio Leone]

...Still very angry for this situation...
I'm feeling we are in a sort of MAFIA connection. 

Anyway, Yesterday I took the decision to start a new project.
I am collecting some new parts for my wedge engine.
I asked for a brand new set of pistons (CR11.5/1) to CPS, the Mecapart supplier.
Also, I will put a brand new and enlarged valve trains and I will port the head.
Of course I will have an uprated camshaft.

I will go for G1 configuration because as G2 the car can't have any improvement.
I will make the car as per the one has raced in Sebring 1969, with 6 inches wheels.
I will keep the stock header, intake manifold and carburettor (SOLEX).

I will post some pictures on the coming weeks....
 

[Serge]

Valerio,

Nice to hear that you're not giving up! Do you have any notes or info on the Sebring 1969 specifications? At least the rules for G1 are pretty clear.

Also, did you design the piston yourself, to get the correct dome height for the compression? Do you have any technical drawings?

And does anyone by any chance know the original wedge head spring rates for the double valve springs in the Lotus spec engine? Or for a modified engine? I only have standard R16 valve springs and they are not enough, not even for the standard lotus camshaft.

I don't have a standard twin choke solex carburettor either I think, but I'll need to check my parts when I get home.

Ciao Serge,

it's good to hear from you.
Just to let you know I personally take this challenge against the federation  just like a sort of time break.
I will work against the idiots (and mafiosus) that don't want to recognize a real race car and I will promote the right we have racing with the same car configuration. 

Regarding the Sebring specification I have some pictures where the bigger wheels are displayed.
I also have the entry List.
I've no other information, but I can say that nobody is able today to recognize a weber or a solex.
I will go for a single weber 40DCNF since they fit on the stock manifold.

Regarding the pistons from CPS I've just made a mold of my combustion chamber and I sent to them the specification as follow:

diam 77 (using mecaparts liners)
wirstpin 20 blocked into the conrod

I also sent to them an old piston.
If you are in need I can help you, they are Italian but for sure they speak "Engliano". 
Please note I have unshroud the area near the valves. So it's better you send your own molds.
price is 186 euro each tax included.

Regarding the springs I have solved the problem using a spare from Fiat X1/9, but you could ask to Catcam in Belgium, since they have a huge catalogue.
I will also change the valve train using 7mm stem instead of 8mm, made to measure from IVAM (italy).  For the valve guide I will ask IVAM as well.
I will use a made to measure retainer (using the valve spring locks of Renault gordini engine 1300)
