I wanna try get my beetle to redline faster and just rev faster. How do i do this.

Its a stock 1.6 at the moment and i wanna just give it a pep up.

Thinking about slightly larger cam, ratio rockers.

Will this make it rev faster??

I believe You need a larger Carburetor and extractor exhaust system... electronic ignition system... etc..

the standard beetle engine is NOT a high revving engine...
nor is is powerful compared to other 1.6 litre engines.

Supercharging or turbocharging will also help....

dude... larger cam means, cam, bearings, seals and basically a rebuild. save your cash and buy a bigger engine. it may seem appealing to bolt on a bit of extra HP.. but with an older engine, its not worth it. you'd really be better off getter something bigger or an engine someone has already spent a fair bit of time on, that has a little extra go.

A lightened flywheel will also get you there faster... but usually needs more HP to keep you there.

i only said cam as most people selling theier bugs say its got a larger cam in it but its still a 1.6

i have a set of extractors and would go to duel cabrs but its a single port head and i havent seen any single port carbs on the net for ages.

thats half your prob. the flow on like a 1776 with twinport heads, slightly larger cam (even a w100..) and twin carbs (like basic webers) is going to be massive advantage.

If your thinking more cheap short term... extractors...and ignition are going to help... but not enough for it to be a superduper engine.

twin carbs, good exhaust and lightened flywheel are a good start without opening it up

but thing you have to consider, taking it over 4500 on stock crank, its not gonna last long
case will flog out pretty quick

if u wanna revvy motor it really needs a CW crank and a balanced bottom end for starters

Modding a 1600 just isnt worth it IMO (unless you're trying to stick to a class)

it can be, you just have to choose mods that all compliment each other

its pointless chucking decent carbs on, if your gonna leave heads stock, conversely big valve heads and chucking a huge cam in is pointless without good carbs or the right zorst

it can be painfull learning experience for a first timer
but it can be done

my used and abused stock 1600 with the turbo or blower on woulda creamed most of your average 1776-1916 K-dog engines, and that humble little 1776 of Daimos would embarrase plenty of vw engines way bigger than it too
you can get plenty of power from small engines

Turbo or blower is a whole different story though 😂
And 1776 isnt 1600 :P

I dont think modding a stock 1600 is a complete waste of time either. A set of carbs can be reused on the next build, ported heads can be reused, header can be reused, ratio rockers can be reused if the new cam is not a lump stick. You can have fun right now killing that 1600 then move on to larger engine and have some parts you can reuse. Cake and eat it too!
