412 - Series 1 to Series 2

Hi There

Could someone here please tell me if the spec and/or effectiveness of the brakes and rear axle changed from series 1 to series 2 on the 412?

(Power dropped notably - 330 to 170hp, I think - and it's got me thinking...)

Thank you and best wishes to all.

FYI: If the 412 series 2 is fitted with the Chrysler E58 360 engine, then it would have produced in the region of 220bhp, a drop of some 40-50bhp from the E64 400 used in the series 1. The E57 360 produced 170bhp.

The E57 is distinguished by having a twin-barrel carburetor and single exhaust, as opposed to the E58, which has a four-barrel and twin exhausts.

It was my understanding that Bristol used the E58 in the 603S and 412S2, although I could be wrong. The figures quoted are net.

I don't think so. And the headline power is not that different and the performance even less different given the weight saving. Peter

Great.

Happy to hear it was 'born' with 220bhp, not 170!

Currently having total engine rebuild as quite a few of those horses had escaped. Hopefully we will find bigger, stronger ones to replace them!

Thank you both for your replies.
