Abarth SE035

[mirafiori76]

Here's another question for you all:

How come the mechanics couldn't get more then 230 bhp from the 1995 cc engine used in the group 4 rally cars, whilst they managed to get 315 bhp from only a 1452 cc engine with just a compressor?

the 2 ltr group 4 engine is normal aspirated unit the other is supercharged, no idea what boost levels they were running mind you, but achievable.

Hi Chaps,   

  I used to work for Allard Turbochargers around that time, Allan Allard did a few trips to Italy with some large superchargers, one an Ro20 for 2 - 3Ltrs  and an Ro34 for upto 5Ltrs I think it was.  I imagin they tried these and then started making there own.  I can tell you we put an Ro20 on a 1500 A seres (Mini)and it made it go scaty.  So the same on a fully worked twin cam 16v,  300bhp should be well in there.

Solved...

I will have a go at contacting them via the official channels to see what if any info they have.

I sent Modern Abarth an email on Saturday night just asking for info on the 035.

No reply as yet, but its not the 1st time they have not got straight back.

[mirafiori76]

It would be nice if they could tell us more. But knowing Fiat..

I?d be very curious what the boost pressure on the 1452 cc engine was and the torque achieved also.
Comparing its 7,8:1 compression ratio with the 7,5:1 of a standard Volumetrico where the 0,45 bar overpressure gives some 20% power increase,
I?d guess the boost on the little TC must have been at least 2 bar.
What do you think ?

i some of the F1 turbo cars had 2.4 bar 35 psi , so fiat would be  on par with that

[mirafiori76]

Gremlino,

Any word yet from Fiat or Abarth?

[Henk]

2.0 bar, Would that be possible with a roots blower?
The blower itself is not compressing the air but due to its drive ratio supplying more air then the engine stroke thus creating over pressure in the manifold.
I did read that these are not really suitable for high pressure as the losses are quitte big...
would this 2.0 bar be possible with a different drive ratio?
Just a question

[mirafiori76]

Just look at the size of the blower. It's huge. Could be possible to obtain 2 Bar or maybe even more.

Any word yet from Fiat or Abarth?

In a word.... nothing!

I have found that since the re-born company has grown they are not bothered with general enquiries on past models.

If you ask a question relating to the current production models they give you an answer within a day or two.

When they first mooted a return of the brand the PR machine at Fiat would go into the archives and come back with at least a photo, ok it might be one you have seen many many times but it was something.

The annoying thing about the company Archive is that there are very few original pics that belong to Fiat. The majority of old photos were taken by studios contracted to Abarth, these Studios are now mostly defunct but they are in the hands of private collectors/publishers/families of Photographers.
Every so often a collection will come to light and we see a few new pics..... mostly with a copyright plastered across them. I have recently been shown a series of original private collection colour photo slides with at least 2 or 3 from the original 131 Abarth Stradale press launch but the current owner is undecided whether to sell them on or even publish them (the answer is straightforward.... sell them to me and I can put them on here!).

From Abarths re-birth (when they could be bothered to reply) Technical data appeared not to be available unless it was published elsewhere. This leads me to think that they just got company bods to trawl through the net until something relative was found to answer someones question.

All a bit frustrating but I will keep looking for new info either in publications or on the net.

I have just seen Alberts Racing&Volu aticle in Automobilismo thread with the white 035 pic.... there must be more out there 

[mirafiori76]

It's frustrating. And it has always been this way. Same with parts for cars. I was Fiat mechanic for years. Trying to get hold of parts after about five years since the last release of a model always was a problem. Let alone, Abarth parts.
When I got my first 131 Racing, back in 1987, i had to go to scrapyards because the Dealer i worked with couldn't get them anymore.
What is it with Italians? 
Take Mercedes now. Every part from every model trough the years is still available. New. I have a W123 280 TE from 1981 and i can get any part from new stock. Fiat/Abarth should take an example from the Germans.

[mirafiori76]

Does anybody know the whereabouts of the 035? Maybe he could winn some information about the car. Maybe take some "important" pictures?

Graham, Mike, don't expect an answer from Abarth. I was there with my Volumetrico. First they didn't know the Volumetrico AT ALL. Answer was, nice car, but this is NO Abarth mister You can imagine that after I showed an original brochure  they were surprised and we had a nice talk, testdrive in the 595 esseesse, show all building etc, But I had to tell everything about Abarth history. It works this way almost everywhere, except in Germany( and Peugeot as far as I know) These manufacturers care about their history.Sorry I forgot Alfa, there are people who also do their best. But 100 year Alfa was dramatical organised and a shame for this great marque!! Fiat doesn't care too much. Even a quite well known car historian(name in PM) who works for Fiat, cannot get in the Fiat archive. Actually that's a shame. It could be a dreamjob for me working there and organise a lot of parts to be re-manufactured. There must be a nice worldwide market for a lot of parts.
But lucky us, we are there together, to care for the cars and the history, great isn't it
