DSL Posted August 28, 2007 Share Posted August 28, 2007 Anyone remember from their dyno plots what sort of power approx they make at 5500 / 6000 / 6500rpm, with the 1444 cams fitted 🤔 Cause thats where my map runs out at the moment, feels nice & torquey then seems to get into its stride big time around the 5700ish mark 😬 Although its a map done for the previously fitted 2180 cams, seems to run pretty good on it Link to comment Share on other sites More sharing options...

martinwhitcher Posted August 28, 2007 Share Posted August 28, 2007 That is my engine, and what a wonderful engine it is...... 😬 Martin MW 51 CAT Superlight No.171 now known as:Superlight DVA 250 Link to comment Share on other sites More sharing options...
Mark Durrant Posted August 28, 2007 Share Posted August 28, 2007 Darren Richard Andersons 1.9K with 1444 cams made 252 bhp @ 8600 rpm and 174lbft @ 6085 rpm on Steve Greenald's rollers recently. When are you getting yours mapped? Mark D Comp Sec Link to comment Share on other sites More sharing options...
DSL Posted August 28, 2007 Author Share Posted August 28, 2007 Nice plot Martin, Dave was saying what a nice motor yours is Thursday, night shift at Steve G's place Something around those sort of figures would be nice Link to comment Share on other sites More sharing options...
Mark Durrant Posted August 28, 2007 Share Posted August 28, 2007 Darren Hope it all goes smoothly and dont forget to take some Hobknobs to help the two Steve's find those few extra BHP that make all the difference 😬 Mark D Comp Sec Link to comment Share on other sites More sharing options...

silver-7 Posted August 28, 2007 Share Posted August 28, 2007 my 1.9k made: 5500 rpm - 165 bhp 6000 rpm - 205 bhp 7000 rpm - 238 bhp 7500 rpm - 248 bhp 8000 rpm - 252 bhp 8496 rpm - 259.3 bhp with power still climbing ! 😳 179.8 lbft @ 5974 rpm 😬 Again on Steves Rolling road on 1444 cams, 32.5mm inlet, 28.3mm exh VHPD head, Steel crank, Standard 4 - 1 R500 exhaust. Pity ive sold it ☹️ but did it fly up the pyrenees mountains *thumbup* *thumbup* *thumbup* regards Alex Edited by - silver-7 on 28 Aug 2007 22:09:10 Edited by - silver-7 on 28 Aug 2007 22:10:24 Link to comment Share on other sites More sharing options...
David Ward Posted August 28, 2007 Share Posted August 28, 2007 My DVA 1.9 with 1444's but a "standard" VHPD crank and rods made 258.5 bhp @ 8179rpm and 166.9lbft @ 6515 at Emerald last year. We've done no fiddling with the induction or exhaust yet - it's on an R500 4-1 at present and the general view is that a 4-2-1 setup will find me some more torque once I can stop driving it to do some back to back tests. Looking at what you say Darren, mine really picks up from 6k (170bhp) to 6.5k(210bhp) and then on from there 😬 V7 HPD Link to comment Share on other sites More sharing options...
oilyhands Posted August 29, 2007 Share Posted August 29, 2007 Hi Darren, Depending on exhaust configuration (4-1 manifolds have a dip around 5000-5500) yours should do between 165 and 180BHP, Richard Anderson, David Ward and Alex Minchin's engines all have pretty much identical specs to yours, but Martin Whitcher's has larger inlet valves and a bit more torque as a result. In my experience Steve's rollers tend to read around 4-5% higher than Dave Walkers. Let me know how it goes. Oily Link to comment Share on other sites More sharing options...
DSL Posted August 29, 2007 Author Share Posted August 29, 2007 How's the holiday going , bet your itchin to build a K as its been at least a week since the last three flew the nest 😬 I don't have a mobile no for you Dave, or I would send you a text with the results Link to comment Share on other sites More sharing options...
oilyhands Posted August 31, 2007 Share Posted August 31, 2007 Hi Darren, Holiday is hectic, 2500 miles in 10 days, but very enjoyable, getting withdrawla symptoms.. Saw the results, they sound very pleasing. Oily Link to comment Share on other sites More sharing options...
