Thread: How much power for a sub 8 minutes lap?

  1. #1

    How much power for a sub 8 minutes lap?

    A question posed by a mate who drives the wheels off his 1.3 mk2 Golf. What's the lowest power you would need, in a really good car, a modified saloon Road car, not a Locaterfield67 or single seater, with lots of track knowledge and skill , to do B2G in sub 8 minutes?

    Just for fun.

    And similarly on a bike?

    I think £ wise cheapest way must be on a bike, but could be proved wrong....

    There are a glut of yesterday’s heroes at the low 8 minute marker.

    Pick one with a turbo, throw a remap at it and the most sticky new tyres possible and you’ll probably find the same pro driver that got the original time trim enough seconds off to get under 8. Not forgetting the year-on-year improvements to the track.

    I’d probably start with a Mégane 250.

    I’d suspect that you’d have more fun elsewhere or could start with a much cheaper base model and spend squillions, but the logic has to be in getting a car that is close out of the box and find some cheap BHP and grip.

    Check out dannycd2 on you tube he has an e46m3, a mr2 with k20 type r (200hpish) and had a modified dc2 he drives the wheels off a car and can do 8 mins btg in all of his cars.

    edit - gives you some idea of the pace required....

    He never managed to beat 8btg in the dc2 and he tried VERY hard to do so

    Actually Nige, it was your car got me thinking. You're around the 7.30 mark iirc? With 300+ bhp, Aero and proper tyres, suspension and diff etc.
    Take 100bhp off your car and what time do you think you could lap the Ring in?

    He did 8 mins flat in the dc2.

    My Gt86 with around 250hp weighing about 1300kg at a guess would do a 8 minute BTG. Not in my hands but it would.

    Which isn't sub 8

    That lap by Robert in the mx5 is a skill and commitment level not really applicable to us trackday drivers

    That'll teach me to read the thread properly lol

    Ace lap in the mx5

    Still gutted he didn't have a pax seat :D. Nice guy as well as mega pedler too. Easy to see why he has (had?) his job despite being so young!

    Agreed re a mere mortal trying that :)

    Yea, and hilariously never got down to 7:59 despite trying too hard.


    IMO he focused TOO heavily on the lap times. It became a bit of an obsession then when he didn't manage it he seemed to go totally off lap times altogether.

    Ive got an 8min 14 sec lap in with 300Hp/1010kgs Evo, and Im no expert. I guess in the right hands it would go sub 8 with ease.....

    If i pluck up the courage to bring it in October to the Circuit Days event and not hire.....Would any expert care to try

    Certainly it will do it with ease, 8 14 is 1200kg 220bhp e36 328 pace in normal (not Robert mega talented) hands.

    Is answer to the sub 8 & power question, for a normal car so not a lightweight Caterham etc so a Hatch, mx5, saloon etc in normal hands I think near 200bhp, for mega talent less needed, see Robert above! I think he can do a sub 8 with 150 in mx5, the more crap the driver and also the heavier the car the more needed, & a tad of torque is useful,
    & old skool car like a mk1 or 2 golf etc will lack on handling vs modern stuff.

    I think my mate needs to improve on his current 65bhp so lol.

    300bhp is doable for mortals, you just need to be able to push. A remapped meg250 in standard form will do that

    250bhp you have to be pretty darn good, or losing weight out of a normal car to improve the bhp/ton. Need sticky tyres

    200bhp you have to be expert and probably fettled the car in many other ways. No passenger...

    sub 200bhp you have to be a koenisegg test driver. I believe his MX5 is c. 190bhp

    One thing to think about is that the track is NOW a lot faster than ever with a lot more grip.

    If you can get a swift around in 8:25 or 30 it was one of them a few years ago your probably looking 8:15 /20 now with the changes.

    Yeh the track is a bit easier and as a result faster these days

    I run 7.30s with 370bhp. 1150kg, R888 , front diffuser.
    I don’t have ‘that’ many laps, and I reckon with some more brave pills it could go at least 10secs quicker.

    You don’t need that much power to go sub 8

    Besides,,,,, sub 7 is the new ‘thing’
    SILVIAAAAAAAAAAAAAAAAAAAAAAARGHHHHHHHHHH S14!!!!!!
