Much less useful for what?

Driving up a hill at 55 mph and try to pass without shifting, vs the 220 mph available and totally unreachable top speed.

Slower off the line, geared for MPG and not performance on the top, thats less useful to me.

Its not the abyss to hell, but its not optimized for what I want either, just mpg.

The gear stuff is in the hybrid transaxle thread that is currently being discussed.

For my manual G28:08 final is 2.75 I think, G28:10+ goes to 2.20 for a few years, but other ratios change inside the tranny too.

Mark - Nice layout of 16v to 32v info. While <IMHO> I don't completely agree with some of your 16v preferences, this is a great Beginners Guide to Model Familiarity. Driving both prior to purchase or either one would likely change many pre-conceived notions about 16v'ers and substantiate many comparisons you've pointed out. Appreciate your time composing it.

$5250 buys a non-intrusive install and solid performance for 32v - no 16v yet, other than a universal kit and their support while you set it up yourself. They are actually the 928 house for http://ststurbo.com/. Seems like a nice system and STS has a solid history. That said, SC's are a proven option on 928's, from reliable suppliers that reside on Rennlist, so you'd have a huge resource pool to help work through any issues along the way. Good luck.

It is called a fat wallet, and a damn good mechanic with kids that need to goto college.

Not sure 928's were truly designed for stop light to stop light.

I don't mind shifting, or would have gotten a slushbox, However finding a good 2.27 or 2.64 RnP set would be of some interest.

Alright I'm confused, what's the final drive on a '83 S (usa)? Also what is it on an '84 S, since we got the transmission (and I think differential) from an '84. Where can one find all the info on gearing, anyway?

928specialists have a final drive ratio chart-check them out

An interesting thread. There are a few glaring omissions though. The most competitive and robust version right out of the box is the 90-91GT. Also, early cars did not go for anywhere near $100k. The $100k cars were the early 90s and later. Although the 89GT has LSD, beginning in 90 the GT changed to PSD and significantly, traction control was added. Also fittted with, ABS and tire pressure monitoring(all things found on modern F1 cars). Lets not forget the airbags, and aerodynamic package.

4 valve, 2 cam heads were not revolutionary with the 85 928. Dusenburg had them in the 30s, but in a straight 8 engine. There was no discussion of the Weissach axle, which is the cornerstone of the 928 handling.

100K for early cars was in ratio to car prices that year. Ie.. $45K in 79 was like $100K to someone in 95.

Great post. Only 4.7 was the "S" motor ROW starting in 1980. 4.5 was the non "S" ROW but still with higher compression. HP rating from US 4.5 are only slightly higher, however torque showed a larger difference. The 4.7L 300HP Euro is not sluggish by any means.

Thanks for the link anonymousagain - site bookmarked!

Great post Mark. Can you list which years were non-interference motors?

Jim bailey - 928 International

all 83-84 engines are "4.7 liters" actually 4664 cm 3 , the USA engines were lower compression smaller valves smaller intake runners smaller throttle bodies and less camshaft.... The 83-84 G28.08 USA 5 spd has a 2,26 to 1 final drive the EURO 28.07 is the 2.7272...

TRACTION CONTROL ?? did not know the 928 ever had traction control how did that work ?

Part of the ABS if I remember right, wheel spins it taps the brakes.
