My weekend reading was a book from the Brooklands book series: "Ferrari 1977 - 1981". Nice book for those of you that don't have it, with road tests drawn from Autocar & AutoSport (UK), C&D and R&T etc. All journals I think we'd tend to trust, or at least respect their opinions.
In their articles of the day Autocar reviewed a Euro spec GTB (10/76), R&T a US spec 308 (3/77), AutoSport a Maranello special 308 (more below) in 10/79 and a Boxer (5/78) and Nick Mason's Daytona, also referring back to the original test in 1971. My interest being peaked by the Maranello Concessionaires 308, I duly noted 4 performance figures: 0 - 60, 0 - 100 and 60 - 80 and 70 - 90. The latter where quoted were 3rd gear numbers as tested, otherwise I interpolated from the 0 - 100 accel numbers (10 mph increments were posted). I found the results intriguing. Some were explained by the text, some not. Anyway, here's the data for anyone with interest to feast on and debate:
For each: 0- 60/0 - 100/60 - 80/70 - 90.
Euro carb 308: 6.5/17/4.3/4.4 (another report was close to the first two, but suggests the latter two are 5.4 and 5.1)
Euro GTBi (81): 6.7/18.5/NA/NA
US 308: 9.4/22.6/5.4/NA
MC 308 w/P6 &?: <6/14/3.5/3.4. For sale through Paul Baber (reg XYU308T)
Boxer (reported to be jetted lean): 6.2/13.6/3.5/3.9
Daytona: 5.4/12.6/3.0/2.8
Couple of observations and questions from the data:
I know the US spec 308s had advanced intake cam timing vs Euros and 200lbs more weight, but the disparity in data is otherwise perplexing to me. Anyone have any data on their own car to post alongside the reported data?
The euro spec Carb car is 1.5 secs quicker to 100 mph (17 vs 18.5), which seems to make sense given the lower reported BHP numbers associated with the 2V injected cars.
The Maranello Concessionaires 308 "factory kit" had P6 cams, a high flow exhaust (sounds like an ANSA from the description) and was reported to included higher comp. pistons but the reporter was unable to validate the latter. Performance numbers are a shade slower than the boxer and, at 14 seconds, they reported 3 seconds faster to 100 mph than the stock 308. Anyone have any further data on what Maranello did as part of these kits?
The Boxer was timed at 163 mph, much to Autocar's disappointment and produced amazing fuel consumption. MC reported afterwards the jetting was way lean.
The Daytona was in its day and for a long time afterwards the fastest production car tested in the UK. |
