As above, was watching a few vids on youtube and just wondered what stage of tune they used to run, would it be something like a stage equivalent??....

TIFF

wouldnt of thought they would of been too powerful.....as RWD and big power/touque on gravel wont be that fast

Interested to know though.......

Until you,ve just come on it and wrecked it Jay.....

Staffi

iTrader: (1)

Really?

So stayed on the T3 etc then?

Suprising how quick a 300 bhp can look when driven properly...


Yet the Manta,s had near on 400bhp didn,t they?

Csm

I thought they were around 300bhp

andrewg

they would of been restricted then.. end of group B was the start of restrictors?

Staffi

iTrader: (1)

Andrew,

But wasn,t there a showroom type class that Gwydaf Evans (spelling) drove in?? i thought they were lesser powered so to speak..

godrikki

Never asked if they used the t3 or not but he did say they were tuned slightly so im guessing they would have the t3 albeit slightly modded to maybe spool faster.Not sure about the mantas but think it would be fair too say they probably wouldnt have 100 bhp more

godrikki

would also have to agree with andrew they would have been restricted after group b

iirc the early group a cars had something like a 45 mm restictor, not the peasly 34mm we run today, the actual figures would have been more like 350hp.

red would do almost anything to get jimmy or colin to win a event, even if it ment fuckin around with the boost,illegal servicing.
in the old days john goff sat in r.e.d's tranny on the event rebuilding the boxes as the cars went through them so quick.
they also used to run colin in a group n car in the group a with just a big group a diff fitted to get it in.
he still won like in group n+ cars.

i was told the group a cars were well over 300 but under 400 btw.

Got an article on the 1988 Corsica winning car here.
Cozzfather is right, Terry Hoyle built the engine in partnership with Graham Dale Jones from Boreham.
Ford Motorsport's John Wheeler reckoned that the standard turbo and intercooler limited power to around 308-315bhp but torque is over 300lb ft from 3500 > 5500 rpm
Getrag 5-speed box 4.89 rear end with viscous diff
Bilstein dampers set at front 325/150 with 500lb springs and rear 260/110 with 200lb springs
AP brakes 12.9 in front
11.2 in rear
Weight in Corsica trim 1106kg

Tested on a wet Boreham track by John Wheeler on Michelin slicks
0-30 2.4
0-60 4.8
0-100 10.8

Max 115mph @ 7500rpm in 5th

Mike,

Those 0-100 times were VERY impressive for that power..

Good info that.........

Mike1

4.89 diff though and slicks remember.... plus 115 max speed at 7.5k revs

bloody hell Cozzfather, anybody would think you know stuff about rallying!

back in the early days of group a the turbo cars were running a 38mm restrictor over the 34mm

i would say they were around 360hp if on the bigger restrictor, i know the escorts were running this sort of power when on the big restrictor !

the torque would have been abit higher than the power, around 390 in the escorts, dont know about the 3doors

Paulo P

Manta's were N/A so nowhere near that. I've got videos of Jimmy driving 3 doors on the Manx and the car does look like a handful and very well driven, I'd also doubt the quoted 300bhp figures but he was properly on it and a commited driver on tarmac.

Good thread

P_is_for_Paul

I might pop along to Kaimes on Sunday, and if i see Jimmy, ill ask him. Not too far from me.

Ill tell him i know Dojj and his WWE crew and he'll give me all the info i need to know

Staffi

iTrader: (1)

Paulo,

I,ve got a few vids of him driving too, agree, he could certainly drive them.....

Mike1

I think the Mantas were up at about 275-285bhp at the end of their run - much less torquey than the Cosworth but 2.4 litre naturally aspirated

Cosworth designed 16 valve head and Opel Rekord diesel bottom end

Staffi

iTrader: (1)

So basically they had the same BHP as todays WRC Cars yes?

What torque have the WRC Cars of today got though?

godrikki

come along mate should be a great day and lets be honest how often are you goin to see jimmy mcrae chuck a mk2 escort about nowadays
