1.9k how much power at........rpm

[DSL]

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

Darren - i found this on the Dyno-Plot website.

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?

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

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 😬

Rach has the Hobknobs on her shopping list 😬

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*

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 😬

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.

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

 

[oilyhands]

Hi Darren,

 

Holiday is hectic, 2500 miles in 10 days, but very enjoyable, getting withdrawla symptoms..

 

Saw the results, they sound very pleasing.
