[QUOTE=Spin9k]Hfalex, regarding our engine discussion so far please just to clarify....
1) You are preparing (at least) TWO entirely different engine setups I think. 1st - CURRENT "std racing 8s" engine is the grp.N FIA regulation mod engine of ~263hp, and 2nd - the OTHER is the "r18 volumex" combo supercharger / turbocarger engine you hope to develop by next year with 350hp@7800rpm and 29kgm of torque on 98 fuel?
Yes, correct. The grp.N FIA is the model which competed in the 2004 italian championship. We fitted this specs engine also under 3 street legal cars.
The supercharged engine will, probably, compete in the European Hillclimb Championship in 2005. It has NOW, with only the supercharger, about 365hp. With the Turbocharger combo we hope to hit the 480hp with 102 fuel.
2) When you say a "PLUG'N DRIVE" ECU... does that mean you redid the WHOLE ECU, not a piggy-back to revise the mappings, etc? But even after doing this you maintain Euro emissions standards? And you COULD SWAP IN/OUT this modified ECU without wiring loom or other changes to a stock car (if someone wanted to for track use:D) ?
Correct, again. A " plug 'n drive" Ecu is an Ecu which complies also FIA grp.N regulation. We mantain the emission standards on ALL the 20 8s we have competing (NOT on the Supecharged version now...). You don't need to modify your wiring loom at all, but it needs to work with the racing exhaust we're using now (complies 93db emissions).
3) When you say ~263hp on the dyno, do you mean at the rear wheels 263hp, a healthy ~80hp gain over the ~180hp stock? OR did you run the engine on a dyno out of the car to get that number?
When i speak about power and dyno i always speak at the crank, as SAE, DGM, DIN etc... says. The gain so is only 33hp (more if you thinkk that we never saw 231 hp EC95 but the best was 221hp, most 218hp...)
4) On the "std- racing 8s" mods can include "Ecu mapping, sw and hw". What other engine sw and hw did you modify, if any?
Astra is a "rally 'n racing" company which only sometimes builds or tunes street cars.
By the way Astra work since 1988 (i presume) in the World Rally Chmpionship with Lancia, then with Seat and last with Ford in the JuniorWRC.
If you like WRC you'll be pleased to know that we had pilots like Tommy Makinen, Gardemeister, Fiorio etc...
In circuit with Maserati and now Mazda (since 99 MX5 and since Astra is the Official Mazda Italy racing dpt since Feb. 2004).
Maybe you remember also the 500hp Lancia Delta wich won the PPO class at the 2000 Pikes Peak (or 2001???). It stands in fornt of my office
.
5) I found what I believe are your rules here http://www.fia.com/resources/documen...04_Art_254.pdf. Is this correct? Fairly stock cars you guys run, at least mechanically speaking. Sounds like a lot of fun competition
Correct (again...)
Thank you.
