Northampton Motorsport Posted March 1, 2009 Posted March 1, 2009 Funny you should say that but Dave's rollers always seemed to give similar figures to our ram 12 but I know of a few people with Duratecs that are getting close to the 200 mark on the Emerald rollers. I should also say that I have a lot of respect for Mr Walker and I don’t think he would knowingly inflate the figures. As I said there are lots of things that would seem insignificant on other engine that really affect power on a Duratec for example, the standard air filter that Westfield supply to fit under the bonnet line is restrictive and the engine will respond to a deeper filter and a hole in the bonnet.

I understand the issue of the filter on the car being outside the engine bay for cooler air, but we also did a run with the bonnet on and strangely, even with a hot engine made no loss at all. Quote
Steven (WE51STE) Posted March 2, 2009 Posted March 2, 2009 Hi, When mine was taken to the rolling road she produced : 176BHP at 6643 RPM and 150 lbft at 4900 RPM Mine was a brand new Duratec engine ( never been ran apart to go through some warming and cooling cycles to check the cooling system / rad / fan all worked OK ) Standard Engine - Jenvey Throttle Bodies - OMEX ECU - Westfield Exhaust (CAT) - Raceline Wet Sump. This was done on the hottest day of last year and the ambient temperatures in the rolling road were 45'+ OMEX who were doing the mapping said that at that temperature you could expect to see a drop of a couple of BHP. They were happy with the figures that the engine was developing. When I asked about claims that with a standard engine with just the TB and ECU upgrade you could get 205 BHP. They did not believe it would be achievable in the real world. From seeing how it all worked, if a company wanted they could easily tune / configure the parameters of the rolling road to get the marketing figures they desired. Regards, Steve Quote
Cleggy the Spyder Man Posted March 3, 2009 Author Posted March 3, 2009 thanks for your responses guys - very odd that westfields figures are so far out, an explanation as to how their figures were achieved would be good ... I get the feeling that if a "non kit" car manufacturer published misleading figures they would end up in the s**t Quote

Cleggy the Spyder Man Posted March 3, 2009 Author Posted March 3, 2009 can't be bothered havent got the time to spare Quote
skids Posted March 7, 2009 Posted March 7, 2009 talk to steve at SBD 304 and more available if you have the money Quote
stu999 Posted March 8, 2009 Posted March 8, 2009 Or fit a heavy breathing 150k Redtop and break the 200bhp barrier (@ Northampton Motorsport) Quote
stephenh Posted March 8, 2009 Posted March 8, 2009 Or fit a heavy breathing 150k Redtop and break the 200bhp barrier (@ Northampton Motorsport) Surely not using standard head, cams, pistons and rods, Stu? The point about the duratec is that we're talking about engines which are standard, apart from throttle bodies ecu and lightweight flywheel. Get the head gasflowed, and some decent camshafts, and larger bore freeflowing exhaust and then see what a duratec will achieve and still be perfectly drivable on the road. You can come for a ride in mine when its finished Stu! Quote

perksy Posted March 8, 2009 Posted March 8, 2009 Surely not using standard head, cams, pistons and rods, Stu? Yep Stu's made just over 200 brake at NMS with DTH Throttle bodies and a Simpsons exhaust system Oh and as Dave says, also ARP rod bolts Quote
stephenh Posted March 8, 2009 Posted March 8, 2009 Well we'll just have to see what my duratec makes with Simon Armstrong head and cams, and kms throttle bodies and Simpson 2 1/2" exhaust; oh yes and arp bigend bolts! Quote
perksy Posted March 8, 2009 Posted March 8, 2009 Well we'll just have to see what my duratec makes with Simon Armstrong head and cams, Please Excuse My ignorance Who's Simon Armstrong Quote
stephenh Posted March 8, 2009 Posted March 8, 2009 He did the head design for the Ilmor Mercedes Indy car engine, then the Sauber Mercedes then the Maclaren Mercedes. He left Ilmor when FIA started restricting power/max revs of F1 cars. Try googling Ulimate Performance, uk websites, and look for cad/cam porting. Serious heritage, for my engine top-end at least!
