1776 power estimate

[Vw1600dellortoGR]

Hello,
I have an engine Combo in mind and I would like some input on the power output so that I can decide what else I need what clutch mostly ,
1776
German CW crank
Stock rebuilt rods
New case
044 panchitos
Mahle p&c
C25 cam

[modok]

85-95 hp

[Vw1600dellortoGR]

Do you think it is a.good combo ? What would it need for more ;

[modok]

The cam is very mild, so it doesn't really NEED heads that big.
a 1776 with those heads could run 7000rpm, but that's not necessarily a great idea to turn high RPMS for most uses, so IMO, what would do the most good is.....
more stroke!

What is the carb gonna be?
My 1776cc, C-25 cam, 40X35.5 valved heads, 1.4 ratio rockers, dual kadron carbs. Dyno sheet says 78 hp to the ground. Plenty of giddy up for me in a 68 type 1. Oh that is at 6500 feet above the sea, lower it would be more for sure.

Use stock heads, single springs, 48cc chamber. Ditch the bigger heads.

The expected output is 0hp since it has no carb(s) or exhaust. What vehicle is it going in?

Just for your information, when asking about horsepower/torque expectations, all you need to include is piston size, head details, ccs, camshaft/rockers, induction, and exhaust. When the combination becomes really wild, other small parts can be a factor like lifters, pushrods, valve make, piston make, compression, intake and exhaust specs.

Those heads are too big for that camshaft. Change one or the other.

What exhaust and carbs will be big factors in whether you should go with smaller heads or a larger camshaft.

I have found two nos dellorto 36 drla with 32mm Venturi's
As for the exhaust I have not concluded to something yet . What would it need to make 100-110 HP;

This is one of my small and quick 1600 type 1 set ups:


AB case line bored to 0,50mm. Surface cut 0,35 mm.
69 mm std crankshaft, 0,25 mm
200 mm flywheel, ligthened 1 kg.
38 mm HD flywheel bolt.
200 mm. std pressure plate. All dynamically balanced.
200 mm. Super disc.
Unitech rods, balanced +/- 0,5 gr.
26 mm Shadek oil pump, full flow.
Scat pump cover.
Cam: Web 163 special grind. 108 lc. Advanced 2 gr. ,472”/,425” valve lift.
CB 30 mm light weight lifters.
Std 85,5 mm Mahle cylinderset. Pistons balanced +/- 0,5 gr. 1,2 mm. Deck height.
Manton Cromemoly pushrods.
Old VW 043 cylinderheads, 35,5/32 mm. Valves, 9 mm. Shaft on exh. Ported to my stage II specs. Scat sgl HD valve springs shimmed 1,5 mm. 9.5-1 CR.
HD Rockershafts. 1,1 – 1 ratio.
Accuvance 009 copy w. Electronic module. Advance curve altered. 3 Ohm Pertronix coil.
Dual 40 mm Dellorto, 32 mm venturies, on Riechert manifolds.
Al´s header, 1 3/8” merged with Turbo Thomas 2” stainless Phat boy. .

Reduce CR to accept medium grade US fuel (9-1) and use a 1½" header instead. An A1 sidewinder would be a good choice. So would a CSP super comp if you are more into stock appearance. Use your 36 Dells, and you will be very close to if not spot on 110 hp.

Keep in mind my measurement was on a dyno. I would bet that at the flywheel it would be greater.

Sorry for the thread hijack.
78 hp on the wheels, at 6500 feet is around 105 hp on the flywheel at sea level (!) How much did you do to the Kads ?

[jpaull]

Did you order all your parts yet? You can have a larger 1835TW without sacrificing anything. Just order the heads with 94mm opening(Same cost) and keep your 92 opening on your case(no cost change). Then you have thicker cylinders then the 90.5's, and bigger 1835cc.

Go with a larger cam, even a 110 would be better then that C25. Just choose something better!

I wouldn't ditch the heads. That would be my FIRST choice for a 1835.

I need to find this magic dyno that gives these high numbers...


I'd keep the heads, up the cam and run dual 40s.

Properly ported stock valve (35x32mm) heads will produce 120 hp so using larger valve heads in your combo will only accomplish a slightly soggy bottom end (and maybe slightly reduced mileage). A 1776 or 1835 would have to rev to 6500 rpm to make use of 40x35 heads. Go with heads that are a better fit for what you're building if you want the best power throughout the rpm range. Al
