The Jensen Roadster specs in the list need some correction:

Wheelbase = 92 in
13" wheel diameter
140hp not 144hp

Dave,
That's 63 HP on a motor that was already 10 years old, and forced into the environmental protection age with an airpump that rivaled an AC compressor, among many other removable smog devices, timing that was so retarded you could start the engine with a lawnmower pull rope, and I won't even begin with the header and exhaust system configuration. Just to set the record straight.

Jake -
Not to damage our position, but . . .
Based on update / backdate, the ITA MR2 should be 115HP. That was the rating on the '88 - '89 cars after they improved the fuel map, changed the injectors, and improved the header.

Line 125 - Opel GT, listed as 102 hp, but that is pre-'71 over-inflated GM rating, therefore it's SAE gross hp. True rating is 90 PS, or about 88 hp. This is correct for 1968-1970 models. For 1971-1973 models the rating is 75 hp. We have to work very hard to get an honest 105 hp....

Line 181 - Opel Sedan, listed as 90 hp, but in fact 1971-1974 models are 75 hp, and the 1975 EFI models are 80 hp.

Line 262 - Opel Manta, listed as 75 hp, which is correct for 1971-1974 models. 1975 models have 80 hp.

Another update - 95% of the Jensen Healeys out there have 4 speed boxes. The rulebook lists 5 speeds, but these are not common, only produced during the last year and only for part of that production run. The 4 speed has the following ratios:
3.12,1.99,1.295,1.00.

Also, valve sizes - 95% of the heads out there have 35.56mm intake and 30.86mm exhaust. There are big valve heads too, but these are uncommon and I've not located one yet nor specs for it.

Updates are in. BTW - I'm just keeping track of HP - if there are errors in the GCR in any of the other info, you should contact the SCCA about them.

Sorry, did not know.
