Gear ratios etc for stroker motors
For all those out there with stroker motors that run on the street what gear ratios do you run and what mods have you done to your transmission to
make it capable of withstanding the extra forces. I am looking at motors bigger than 2.0litres.
Any information is more than welcome..... |

Thanks t2,
Do you know what the ratios are? What is it like for driving around town?
Short of first gear, does second gear allow for a good long pull ie pull you from ~20kph to 70kph easily(thanks to the engine torque) and what is it
like on the highway? |

I have a 2110 with a stock IRS Single side cover box in it. It has a 3.88 r and p. The gears are 3.80 2.06 1.26 .89.
At 7000 rpm it pulls 1. 30mph 2. 60mph 3. 100mph. Cruises in 4th at 65 - 70mph at about 3000 rpm.
I would class the gearing as tall, probably stock gears with a 4.125 r and p would be a better option. Depends a lot on car weight, engine torque, and
the use of the vehicle.
The only mods I have made to the box is a ZF LSD, everything else is stock (rebuilt).

Although my type IV is not classed as a stroker, it is close to 2L  As
you know I haven't had it on the road yet but the box is from a 68 swing axle beetle - 3.88r&p and 0.89 4th. Heavy duty side plate, super diff,
welded 3rd and 4th gears etc. This will be fairly tall but my priority was cruising rather than drag racing, plus the type IV will produce a decent
amount of torque which will suit the longer legs of the box. I'll be sure to give you a drive when it is done 
Brad's IRS box (that will eventually go into his ghia) has custom super beetle mainshaft, 4.125 r&p from memory and 1.04 4th...super diff, welded
3rd and 4th etc.....this will be lots more fun from traffic light to traffic light but not so fun on long drives.

I thought the SSP 3.88 tranny had a 0.93 4th gear as standard, and the s-bug had the 0.89 4th and 4.125 R&P.

Oh BTW,
if you know your ratios and tyre size I can produce a graph if you'd like.

It seems like everone spends more time on the sizes of their engines and alloy wheels than to get the power to the ground.
Has no-one driven a car with a good combination of gears and ratios that suits daily drivers.... I know there will be a lot of opinions on what is
best and how their cars are being driven and that is what I am looking for...
Basically some discussion to help the novices like myself from making mistakes that others have already made..... Thanks to all those that have
already responded :thumb |

I am in the process of going to a 2276. The guy who ported my heads wanted to know - Gearbox ratios, tyre size, car weight, driver weight, carb size,
cam numbers, exhaust size, fuel, compresion ratio, and the main use of the car.
Its a matter of matching it all up to work together. My first combo was a bit to peaky for the rest of the bits it was driving through...

I have spoken with an engine builder on this issue and his advice, which I will probably go with is stick to what volkswagen put together with
reference to the ratios, however he did suggest changing the final drive ratio to a 4.125 (or something like that)...... does anyone have an LSD with
a 4.125 crown and pinion diff to get me out of this mess??? :thumb |

Try having a look through the transaxle forum on shoptalkforums:
http://www.shoptalkforums.com/viewforum.php?f=50&sid=9bd950aeca4898270b2e...
About 12 pages of threads to sift through!
And the transmissions forum on germanlook:
http://www.germanlook.com/Forums/forumdisplay.php?f=13
That might give you some more info perhaps?
