Try turning the wheel either left or right slightly and overtake him next time............... maybe he was stuck in 3rd or summat like that

Naahhh
i thought of 2 things what is our goal?
Building an cruise car? or Building a sportscar?
Every sportscar revs sow i build a Bec. When i have to do a long distance trip i maybe come back from the statement.
But i won a sportscar.
Both engines can make serious huge power. Its just how much money you trow at it.
But the BEC will always win in the corners and on acceleration.
CEC vs BEC for me its like compraing an diesel car and a petrol
You want / like revs or you don´t.
back to watch mode...

I wouldn't get too hung up on power. Get the chassis/brakes/steering sorted and make the car easy to drive and you will always be faster than
someone who struggles to put the power down and has to fight the car. If trackdays have taught me anything it is that to be fast you need to get the
corners right and learn how to out brake the next bloke. CEC seem to be easier to drive and more forgiving to being in the wrong gear at the wrong
time.

Hi shurley this is a personel thing as to what you prefer. Just looked at the 750mc results to see if there was a staggaring difference in performance
as the bec guys seem to think. Results.
donnington taken at random from last years results page.
RGB- front runners 1.17-1.19 180-200bhp
kits- front runners 1.22-1.23 155 bhp
locost f/runners 1.30-1.31 85bhp
Question is what happens when you put 200 bhp in to a cec easily down to the same times as the bec lads but i dont have the offical times to prove
that.
each to there own preference there is no big advantage.
cheers matt

slightly different scenario, but when nationalsupersports was still going vauxhall engined cars always beat hyabusa engined radicals. club &
prosports and sr3's that were about at the time. Either on same power to weight ratio (with ballasting). I only once recall an unballasted (read
high power/weight) prosport with a breathed on 1500 hyabusa coming past a vauxhall engined car and thats cos the guy fluffed it out of the hairpin
leading to the banked corner at rockingham.
Ned.
ps that particular driver has since sold the radical for a v6 cec!

I have a bike so don't feel the need for the sound and sequential box of a BEC. When I build it'll be a CEC as I plan to use it mostly on
the road anyway.
If I just wanted a track day tool I'd build a BEC.

I have a CEC, but like BECs as well - we need a 3rd option in the poll!

naahh
the Third option should be an RX7 or RX8 engine..
because they also rev and make huge power.

You sure the kits only have 155bhp ? the regs allow a lot of tuning in the engine dept (I can think of one RV8 powered car in kits that put out close
too double that) non of which is allowed in RGB, if there is no advantage on track with a bike engine why where they banned from under 2000cc
class's let alone smaller cc class limits ? We have too agree to disagree maybe, on long straights, motorways ect the strong CEC will always
pull thru but somewhere where lots of acceleration is required and top speed is limited by an fast approaching corner then the BEC will take some
licking, of course it can be done but it costs a few $$$$$ to do it.

£ for £ this qoute puts it into prospective...............
Before the RGBs went out the Roadsports Championship had their qualifying session. The Roadsports Championship is an eclectic mix of sports cars,
including Nobles, Porsches, a Morgan +8, a TVR Tuscan etc. At the front of the grid the cars will be costing well in excess of £50,000, and yet the
pole winner (Noble) wouldn’t have made the top three in RGB! Furthermore, the third quickest Roadsports runner in a Noble M12 would have qualified
fifteenth in RGB!
This does illustrate just how quick the RGB cars are, and whilst no one will ever say motorsport is cheap, the RGB Championship does represent
incredibly quick and competitive racing for the money.

As others have said, it all depends on what type of car you want, and where you're gonna use it.
I've had a BEC, loved it for a while, then got frustated with any kind of distance driving, so I'm now build a 280bhp cec which will
outperform my 140bhp bec for sure.....

i intend to build a zx12 bec soon for tracking, but eventually i will build a much larger 3 seater with a large v8, ideally the audi lump  I think
the bike engines are justa whim for me.

HI jon yep thoes times for kits where for the class b zetec 155 bhp cars as the v8 with 300 bhp cant hang on at the corners so overall is no quicker
as said a 200 bhp cec will stay and leave the 220 bhp busa of charsley when he was testing.
2.0 zetec 200bhp
+£750 g/box = £3000
220 bhp busa = ?
But its still a personal choise cec or bec . I just think that the guys with a bec think there is a much bigger performace gain when there isnt at
kit car level.

Bec's lack torque
I have heard from a racing driver that around the track after 70-80 mph the car engined cars do pull away faster.
I have no experience with bec's and have decided to build with a 200 bhp zetec.
Car stripped down I would expect to come in at less that 600kg
thats ( I think ) 300 bhp per tonne?
I would expect 0-60 to be down in the 5's and top speed of around 140 -150
that's pretty good going.
One reason I did go this route though as a direct hit on bec cars is that the car enigined route ( even a modern engine such as the zetec) is much
cheaper.
i.e. I bought a mondeo 2l for £140 with a blowing head gasket head skimming was £80 and I've ported it myself which gets me up to approx 170-180
bhp
All thats left to buy is cams at £200 and enigine managment at £300 Oh and the 40's were £100
That's £800 for a good enigine. All the fireblade engines I've seen are around £1000 and a hyabusa would be £2000 min.
Just my view.

Ah but if you just press vote without selecting one at all, it does accept that.

We got to do some tests with some 1.6-2.0 CEC and mid range BECs. Some 0-60, 30-70, 50-80mph figureE etc
Nothing stupid like busa turbos - cause if i turboed my zetec it would be 285bhp and we could go on for ever!!
Anyway CEC or BEC??!?
I went on price- i didnt want to fork out £1500 for a R1 and £700 for a reverse box so went CEC and now im really glad i did!!!
Even though i still thought a car engined car will and would be much faster especially around the 70-100MPh mark- i think bike engines sound/seem
faster and have more a thrill to them- thats why people think they is a difference- and i just dont think there is in some cases!
But is there anything better than a 4cly grunt from Tbs or webbers..... i think not
So i got a £300 2.0 Zetec and despite want to keep costs low so far on engine ive spent in the region of £2.5k nearly oops sumthing went wrong
there!!
Built, Ivaed, Drove and now Sold - 2011 MNR VORTX RT+ 2000cc Zetec on R1 Throttle boddies.

lets face it both are great
However dont underextimate a cec and what torque can do
My 232hp Vauxhall engined MK would i imagine 'worry' most bec's
