Valentinik Posted June 3, 2015 Share Posted June 3, 2015 Im currently building my car and when finished it will primarily be a road / track day car. However i'm interested in entering a few events to start off with. I've been reading the class discussion thread with great interest but didnt want to post in there to go off topic. I've done a search on here and looked on the MSA website, but I'm not able to find anything that clearly defines how each class differs (that i can understand). Im just looking for a little guidance as to what class(es) my car would be eligible to enter. A quick spec: 2 Litre Duratec engine Turbocharged 5 speed H pattern gearbox sierra lsd FW bodywork with Aeroscreen Any info is appreciated Mike Quote Link to comment Share on other sites More sharing options...
Terry Everall Posted June 3, 2015 Share Posted June 3, 2015 Currently either D, F (road going)or H if on slicks Quote Link to comment Share on other sites More sharing options...
Kyle Posted June 4, 2015 Share Posted June 4, 2015 I couldn't find this either. Has anyone got a comprehensive list? What about a novice 1600 Mazda SDV, aeroscreen, H pattern, 1.5 way LSD? Will a 1600 be competitive in the under 1800cc classes? Quote Link to comment Share on other sites More sharing options...

Terry Everall Posted June 4, 2015 Share Posted June 4, 2015 Should be fine in class A The classes are shown in the Speed Series section "2015 Speed Series Regulations" Quote Link to comment Share on other sites More sharing options...
Valentinik Posted June 4, 2015 Author Share Posted June 4, 2015 Thanks Terry, i've read the 2015 regs but i was unsure what differentiates B from D ( Is it just the novice aspect of it?) and D from F? Mike Quote Link to comment Share on other sites More sharing options...
Terry Everall Posted June 4, 2015 Share Posted June 4, 2015 B and D are just different due to novice D and F are different because of gearbox.....D needs a H pattern box (syncro or dog box) but F can have sequential. F can also have "drivers aids such as paddle shift and traction /launch control whereas D cant 1 Quote Link to comment Share on other sites More sharing options...

darve Posted June 4, 2015 Share Posted June 4, 2015 I didn't realised forced induction cars could go in classes A - D Would it be deemed against the spirit of the rules though? Just interested Quote Link to comment Share on other sites More sharing options...
Paul Morcom Posted June 4, 2015 Share Posted June 4, 2015 I didn't realised forced induction cars could go in classes A - D Would it be deemed against the spirit of the rules though? Just interested The MSA Blue Book defines a formula for dealing with "Forced Induction" - superchargers or turbocharges all treated in the same way. A coefficient of 1.7:1 is applied for forced induction. So, for example a turbo'd 1000cc engine would be the equivalent of a 1700cc engine. A supercharged 1400cc would be equivalent of 2380cc taking it into the over 1800cc class (from a current WSCC regs perspective). This coefficient is accepted across all MSA governed events.

I had read that when i looked into competing with my supercharged mx5, thank you for clarifying Paul. With the coefficient applied the engine would be roughly 3.4L. Would this still be suitable to compete in the larger than 1800cc category (class B whilst I am a novice)? Mike Quote Link to comment Share on other sites More sharing options...
Kevin Jones Posted June 4, 2015 Share Posted June 4, 2015 Sprints have a lower coefficient, 1.4, it's hidden under 10.3.1 pg 339. Quote Link to comment Share on other sites More sharing options...
Terry Everall Posted June 4, 2015 Share Posted June 4, 2015 Kev is correct and at the moment its anything above 1800cc Quote Link to comment Share on other sites More sharing options...

Thanks Kev, I had a quick look at the Bluebook and found 1.7 but was thinking 1.4 but didn't have time to look any further. Quote Link to comment Share on other sites More sharing options...
davidgh Posted June 6, 2015 Share Posted June 6, 2015 B and D are just different due to novice D and F are different because of gearbox.....D needs a H pattern box (syncro or dog box) but F can have sequential. F can also have "drivers aids such as paddle shift and traction /launch control whereas D cant If you have a dog-box I don't think you can run in Class A or B -- even if you are a novice. Road-going cars with sequential gearboxes (whether motorcycle or car derived engines) have to run in E or F. Classes (per the SS regulations) are: 3.1 Classes in the Series will be as follows: The following classes must comply with Roadgoing Specialist Production Cars S.11 A. Road-going Westfield kit cars up to 1800cc (Novice Drivers).Any “H” pattern synchromesh gearbox B. Road-going Westfield kit cars over 1800cc (Novice Drivers).Any “H” pattern synchromesh gearbox C. Road-going Westfield kit cars up to 1800cc. Any “H” pattern gearbox D. Road-going Westfield kit cars over 1800cc. Any “H” pattern gearbox E. Road-going Westfield kit cars with motorcycle engines up to 1150cc or Roadgoing Westfield kit cars with car-derived engines up to 1800cc. F. Road-going Westfield kit cars with motorcycle engines over 1150cc or Road-going Westfield kit cars with car-derived engines over 1800cc The following classes must comply with Modified Specialist Production Cars S.12 G. Non road-going Westfield kit cars with car-derived engines up to 1800cc or motorcycle engines up to 1150cc H. Non road-going Westfield kit cars with car-derived engines over 1800cc or motorcycle engines over 1150cc I. Electric Westfield kit cars Quote Link to comment Share on other sites More sharing options...
