Snowy Posted October 12, 2003 Author Posted October 12, 2003 Yep, I did! I don't understand your avatar, what is that all about? How many of the SEight's have been produced , any idea? Quote
windy Posted October 12, 2003 Posted October 12, 2003 Windy old boy! You don't need to throw any of what you quoted away to get over 200bhp with a duratec, just change cams! According to Steve Broughton (he's done a fair bit of dyno work on the Duratec now) a standard engine, std cams, with bolt on bits will reliably give you just under 200 hp. If you up the revs to get more with cam swap (or without a cam swap) he's found the big end bearings start to rotate within the rods and so you have a serious problem. With a VX this does not happen because the big end shells are pegged. Replacing the std rod bolts with heavy duty items is all you need to do internally to give you a reliable 200 - 210 hp. You don't need to change cams & you don't need to worry about big end bearings spinning within the rods. I assumed that by stating "over 200 hp" meant IRO 250 hp. For both Duratec & VX you will be binning most of the bits to achieve this. With the Duratec the bits you bin will be almost new. Remember also that power is not everything. An engine with lots of torque is more likely to win you races. As a road car engine I'd put the Duratec almost level pegging with the zetec & VX 2 litre lumps in standard form. Personally if I was to build a road car I'd be looking at the lower capacity engines such as the 1.7 Puma engine and 1.6 VX ecotec because they combine lightness with economy & are available in relatively large numbers fornot too much money.

Snowy Posted October 12, 2003 Author Posted October 12, 2003 Tourque it is then, I guess the V8 has this by the bucket full. Cheers Quote

conibear Posted October 12, 2003 Posted October 12, 2003 Windy, re: Duratec bhp. Yes I agree you can get 197bhp in standard form. But you do not need to up the revs to get more bhp, I don't understand that comment. Changing the cam profile, pocketing the pistons (allowing for the higher lift), re-mapping, replace rod bolts and hey presto just under 230bhp @ 6700rpm (Weber RR Sept 03). This is what Raceline, Mountune and Scholar are producing and this also my spec. To obtain 250bhp all I need to do is replace pistons, rods and re-map, still no head work. NO NEED to throw away any NEW bits as you stated. If you think I am talking nonsense contact any of the above performance companies. The Duratec weighs 20-30kg lighter than Zetec and VX and produces bhp ecconomically without much work thus very little stress on the engine thus much stronger. The Duratec is in a different class with regards to power, weight, strength, torque and cost against the Zetec, VX, 4AGE and K series. I know many of you Westie people luv a VX and we are all bias, but there is no comparison. Ian Quote
S8ight Posted October 12, 2003 Posted October 12, 2003 I don't understand your avatar, what is that all about? went toBody Worlds exhibition when it was in London, managed to take a few sneaky pics without getting spotted its basicaly a bloke who has been 'peeled' and preserved Quote
tr mike Posted October 12, 2003 Posted October 12, 2003 Surely the bigger capacity alloy engine has it 'in the bag' because it can be tuned, bored and stroked to huge proportions. It could fly, well almost. I also believe in keeping it simple as well as large. Quote

Buzz Billsberry Posted October 13, 2003 Posted October 13, 2003 The red car would whip the ass of the V8 on the circuit or road When was that then? Hi Tommo Hope you are well? that statement is after driving both of them but my red 2.o 16volter is lighter than my yellow V8, plus the red un' has a competition box that makes all the difference especially with the long 1st and the other 4 come nice and quick where the V8 with R380 box even setting off in second won't keep with the red un' but once you get to circa 80mph then the advantage disappears as the V8's torque starts paying dividends Buzz Quote

conibear Posted October 13, 2003 Posted October 13, 2003 Windy. My comments, that you call pub talk is fact, your statement that ''the Duratec requires to up the rev's to get more bhp which will cause the big end to rotate'' is straight out of the Stella keg. But, you must be a mine reader, co's I hope to do some SpeedSeries next year, once I have learnt to drive the car properly and registered etc...., but I am hoping I have got nothing to prove, it is the developement organisations that have. I think your wet blanket may dry out if you took time to read the reports on the Duratec, but your heads getting done in. I never knew there was a religion called VX. I'd better be careful now co's I'm gonna get my head kicked in. Where do live Windy, I'll show you my car and let you drive it or even better meet at a trackday. I am in the South. Mike H is correct I have to throw away the pistons and rods but they won't be new and it was compared against any other engine trying to get that HP. Ian (What do ya fancy I'm always in the pub).

neilb Posted October 13, 2003 Posted October 13, 2003 The Toyota 4age will give 200 bhp for less money than duratec, weighs nearly half of that of the VX will rev over 8.5k and is still only a 1.6. 250bhp is not unrealistic and if that is not enough, stick a turbo on it and you can be closing in on 400bhp. I figure that the 50kg saved is worth a good 25bhp and it’s built by the japs so it will last for ever How much better can it get??? Quote
