thx very much indeed

I have now got ballpark figures for all the info I required except top speeds, if anyone recalls the kind of top speeds these cars were reaching again it will be much appreciated.

Of course if there is official stat to be found like in this previous post then they are still most welcome, even if only to validate the current info I have.

Thanks again

Mark.

Good luck with everything and I hope you can release F1 77 as a mod or game in the future. And also good work with GT 2002

Cimarosti has

BRM T193 (5 speed) - Stanley-BRM P207
Ferrari (5 speed) - Ferrari
Hewland FGA 400 (5 speed) - ATS-Penske PC4
Hewland FGA 400 (6 speed) - Ensign MN06, Fittipaldi FD05, Hesketh 308E, Lotus 78, March 761B, March 771, Renault RS01, Shadow DN8, Surtess TS19, tyrell P34, Wolf WR1
Hewland TL 2-200 (5/6 speed) - Ligier JS 7
Hewland-Alfa Romeo (6 speed) - Brabham BT45B
Hewland-McLaren (6 speed) - McLaren M23, McLaren M26

I'm suspicious about the ATS, but that's what he said.

His peak BHP and revs is slightly different from Autocourse but not enough to make it worth typing it all out.

[PhantomSBDT]

thats excellent thanks.....

Anyone with any thoughts on estimated top speeds in this year of racing ? 200 mph sound like a reasonable guess at minimum aero settings for somewhere like Hockenheim ?

thx again

Mark.
