How easy is it to get a stock 60hp 1600cc up to 100hp at the flywheel, like what all would need to be done...I dont want to bore or stroke it, just make it a lil quicker. I heard from some older guys here in my area that a bug with 100hp is pretty quick :?: i finally got my motor at my house now. it has a chrome shroud,tin,dipstick,generator an stand, an pulley as of right now though.
thanks :D

Dude, why bother?

Instant 100 HP recipe:

Take one 1600 engine, and build a 1914, with decent dual carbs, Engle 110 cam, big valve heads, and merged exhaust. The more you put into the heads, the more power you will make.

mostly because i dont feel like having my motor machined for 1914cc pists (94's) plus i dont want a monster in my bug yet ;) an no, i dont consider 100hp in a bug a monster :lol:

Ok, so you install some high flowing heads, and a big cam, and you have a high strung 1600 that's nearly undriveable in traffic.

Or you boost it. Be sure and carry a broom with you. hehe

With the correct carbs /cam/heads and exhaust and retaining drivability expect around the 70/80hp mark tops.

(the 1600 is rated mainly at 50hp)

heres the stats of my warmed up 1600.

new as41 crase set up for full flow
69mm counter weighted crank
13lb flywheel
slr xv260 cam with 112 lobe centers, .418 lift (when assembled and measured came out to .420)
stock vw 1.1 rockers with swivel feet adjusters
new slr lifters
stock vw heads with an awesome port job, heads flow at 127.45 cfm intake and 110.77 cfm exhuast and 7.6:1 cr
85.5 new cima/mahle pistons and cylinders, balanced.
rebuilt and balanced stock vw rods
GB oil pump and pump cover
40mm kadrons with 130 main jets and 55 idle jets on short manifolds, also match ported to the heads.
csp linkage
GB 1.5 quart oil sump
S&S 1 3/8 header with single quite pack
stock german doghouse and engine tin

now for some dyno numbers.

peak torque: 82.8 lb-ft @ 3900
peak hp: 70.8 bhp @ 5000

of course since the location of the dyno is alot higher in elevation the numbers should be slightly more where im at closer to sea level. and the torque curve is awesome, making 80.2 lbs-ft at 2200 rpm dropping off to 77.5 lbs-ft at 4900 rpm and 64.5lbs-ft at 5500 rpm.

also for the fun of it we ran the engine on the dyno with no fan belt, with no other changes.

peak torque: 93.7 lbs-ft @ 3900
peak hp: 85.6 bhp @ 5100

Sure you can get 100 HP out of a 1600cc. But in reality it would be cheaper to get 100 HP out of a 1915cc

Please note a 69 X 94 = 1915.38cc. I still would like to know why everybody calls them 1914cc.

Wed Sep 06, 2006 6:38 am

Surely you can squeeze a little more than 100hp out of a 1914... my Chico built engine made 136hp on the dyno

Wed Sep 06, 2006 7:14 am

That's why I said "instant". It's hard NOT to get 100 HP out of a 1914. But some have done it. lol

small turbo kit on a stock 1600 makes a nice driver, Cameron had come across and old rajay kit that was very small like a t-2 with a bendex sidedraft and it screamed! Cameron also built a set up for Jeff Lovell's street 1776 that was based off of a bug pack street header, china t-3 and a small side draft that kicked ass. simple but effective!

I have 1641 motor with p/p stock heads, webcam 163, 1.25 ratio rockers, 9.1 c.r. (we have RON 98 fuel), Kadrons 40 with 135main. I don't know how much hp and torque it produces but it accelerates really fast from 2500 to 5000rpm and out performs most small Japanese NA cars.

thanks :D

First things first - ditch the chrome. It will only promote excessive heat.

Next, the easiest way to get "a lil quicker" as you put it would be to swap the stock cam out for something with more kick, get some worked cyl. heads, an ignition system, & some better carbs.

Decklid prop - the righteous way!

Wed Sep 06, 2006 11:02 am

1600cc + $10,000 US dollars = 100 HP. :lol:

Sure you can do that much HP...just have the money ready. It will NOT be cheap.

I disagree. Here is the best recipe for creating 100 horsies from a 1600cc that I can back up with test data and extensive dyno stats:

Chrome dipstick=5 horsepower
Chrome fanshroud=15 horsepower
Chrome valve covers=10 horsepower 2.5 more if billet
Chrome generator stand=2 H.P.
Chrome backing plate=7 H.P.
If it's all EMPI stuff add an additional 10 H.P.

I think Jake and Mark would tend to agree with me?

Outrageous compression ratios, excessive pinging, race gas, turbos...priceless.

Dude, listen to the guys that know, bump it up to 94 mm pistons or 92 mm thick walls with a pump gas tolerable CR. This is the biggest, most reliable bang for your buck.

Wed Sep 06, 2006 12:23 pm

ok heres what im not understanding..your saying bump to a 1915 an you get 100hp.why bump to a 1915cc to get 100hp when i only need 40 more hp...i dont care bout whp :lol: so whats the problem with just building up a 1600cc with 60hp stock.. up to 100hp? an i dont think it would take 10grand sorry but thats complete b.s. dude :D if that was the case then id think vw's aircooled motors suck if you got to bore them out to make just 100hp (40hp increase) i mean honda guys swap motors just to get power...an vw owners bore out an stroke the motors why not stick to stock motor with mild modifications.

bigger isnt always better (to me anyway)...not to be rude sorry if it seems that way, an about the chrome i doubt it would bring heat on, i mean i got my decklid open 2inches so it shouldnt be as bad as you claim.

Wed Sep 06, 2006 12:55 pm

hondas make power with bolt ons.... all the bolt ons for vw wont get you 100 hp unless you turbo. .. a stock 1600 with header, and kadrons 1.25 rockers, the baddest ignition, and a tiny lil power pulley wont get ya 100.

3 choices
nitrous=blow motor up
turbo=money!
do what these educated people on the samba tell you.

sounds like you need a 5.0 those have bolt ons that will get you into the 12s. donate your car to me and go get a mustang

oh yeah... CHROME SUCKS!
