Engine and camshaft choice
I`m buliding a 1584ccm engine.
The goal: a solid reliable street engine with optimized power between cruise speed (about 2000 RPM) to maximal RPM at 5500 (original crankshaft). Parts I have: 2 x 36 DRLA dellortos Scat 1,4:1 rockers. Thereby I can use gentle camshafts DRD L3 heads, flows up to 130CFM@28", up to 0.480" lift / 12.2mm. The heads are cut 2.5mm and should be around 40+CC. Deck should be about 1.4mm, giving a compression static of about 9.0 Tri-mill exhaust, I want it to exit through the stock ports. OEM Mexico oil pump with spin-on filter. Therefore: which cam should I choose from the list below (4-rivet camshaft)? The timing is given with 1mm valve clearance, I was told US cams one should add 20degrees to compare. Or subtract 20degrees from the ones below. Schleicher Spezial Nockenwellen Käfer "Made in Germany" mit tiefem Zahnrad Öffnungswinkel Nockenhub 292°* Bus 8,50 04013 211,18 308°* Strasse, 1 Vergaser 8,45 04010 211,18 296°* Strasse, 1 Vergaser 9,00 04020 211,18 316° Sport 8,50 04030 211,18 324°** Sport Racing 9,40 04040 211,18 330°** Racing 9,50 04050 268,47 332°** Racing 10,25 04060 268,47 * Nockenwellen auch geeignet für einen Originalvergaser **wir empfehlen Doppelfedern |

No comments?
Is there a rle of thumb of what RPM range the camshafts are made for? (I know this also is a variable of displacement/compression) |
