cam choice advise for 2550 T4 in bug
Posted: Sun Nov 18, 2018 5:31 pm
I picked up a used but practically new engine a while back which I am rebuilding (hopefully early next year) to go into a Germanlook 1302S.
The aim of the car is to fit somewhere between a daily driver and a weekend warrior but remain easy and smooth to drive.
I've already got Kerscher shocks on it, with 280mm VR6 disc brakes all around. I've added a lot of sound deadening to keep the car quiet.
FWIW, my other bug is a 195hp 2332 street car, now I am looking for something a bit more relaxed and quieter that I can do distance in if I want to.
the main parts for the T4 is as follows
78mm DPR crank
early (first gen?) LE180 heads, 42x38
102mm QSC
JE forged piston with 16cc inverted dome. I'll be cutting this down to increase CR or if needed, I'll get flat tops. I'd like to avoid cutting the heads so I can keep them as strong as possible.
1.3 rocker arms
44Idfs
aly pushrods (AC.net)
Street beehives from AC.net
A1 muffler 1/5/8 sidewinder, stainless.
Now for the cam?? With the parts, I got a EMW "H" grind with straight cuts. I've already backed off to helical gears as I hate the sound of straights.
My gut keeps pushing me towards the Webcam 86A camshaft.
My aim is big torque (which I'm sure either cam will give) with a peak hp in the 160hp range, somewhere between 5000 and 5500rpm, while being relatively quite as far as mechanical noise goes.
What are your thoughts when comparing the EMW H grind to the Web 86A on a 2550cc build?
Thanks
