3.2 vs 3.6 0-60 times???

In a slightly earlier post, a few guys here said that they were able to get 0 to 60 in the 5.3 to 5.8 times on non abused 3.2's. Im curious what times are you capable of with a sweeet running 3.6. Has anyone here had the luxury of getting the best time you could get with you 3.2 and then do a 3.6 conversion and check your times with the same car and weight as before with the 3.2 engine??? Numbers anyone?? Just how much faster is the 3.6 over the 3.2????Thanks for any input, thoughts!!Mark

I don't have any hard data to share, but can tell you that my new 3.5L (from a 3.2L) is a HELL of alot quicker then the 3.2L ever was. No comparison, whether from a standing start or travelling in-gear. The 3.6L conversions would be just as fast, if not even faster. There are plenty of guys who have done the 3.6L conversion, I am sure they can provide you some hard numbers to chew on. It is big fun!

I think Thom Fitzpatrick has timed his 77 Cabrio with a 3.6 at 4.3 seconds to sixty.

Of course Thom's car is "special", but I do remember him turning in the 4's on several occasions, so I'd say in the 4's should be a given for a well driven 3.6L conv.

no hard data here, but my friend with his stopwatch sitting shotgun, clocked me at 4.7 seconds. Give or take a few tenths for lag time in both starting the watch and stopping it, so it's probably somewhat accurate, atleast enough to give you an idea of what a 3.6 in a early car is capable of.

surely the biggest gains of upgrading from 3.2 to 3.6 are to be found with in-gear acceleration ?

Remeber that any of the three, .4 /.5 /.6 liter transplants/rebuilds are typically light weights as well. 2400# seems to be the starting point for most of these cars.

Going under 5.0 sec 0-60 isn't going to be a big deal if you don't peel off the tires or burn a clutch out.

I have the baby brother of the crowd (3.4) and it has done 4.9 or less on a hand held stop watch a couple of times with little effort.

Yeow - that's fast. But someone please tell me (again) how a small ring and pinion 915 gearbox is to survive a 3.6 at Willow Springs, Mulholland, or just regular stop and go driving?

Not sure many are running a small ring and pinion David.
I would bet short gears are more common.

In the grand scheme of things gear boxes are cheap to rebuild or replace

LOL! No chance the fifty bucks in my wallet will cover it, though, right?

I've done a 4.3 0-60; I need to find my G-tech and test the car in it's current roadster configuration. I'll bet I'm in the mid 3's easily.

David, is that $50 for the rebuild or the short gears?

If these guys are like me the reason I don't have $50 in my wallet is I have short gears and saving for a rebuild

Mid 3's? Now that is fast!. What the hell does your car have in it to do mid 3's? I don't even think some ruff cars do that? Do you have a tall first gear or what?

It's not so much what is has in it, but what it doesn't have in it. No roof, no carpet, no insulation, no HVAC, LTW battery, fiberglass doors...

HP\weight-makes sense. My little poopy 72 with 2.7 and e cams with nothing in it weight wise surprises the hell out of a few cars, but I'm looking at maybe mid 6's. The reason why I'm asking is because my supercharged viper did 0-60 in 3.2 seconds and I about shat myself (I was not driving it). But the viper is a boat!
Gobble, gobble everyone.

Thom - isn't it hard putting all that power to the ground? Mid-3s, and I'd think the tires would be spinning in second and third gear.

On my last test run, I was getting wheel spin well into 3rd.

I can't wait to get back into a 911. Wheel spin in 3rd is pretty amazing considering the rear weight bias of a 911.

Thom, I'd love to ride shotgun sometime . Dave, I ate my original mag cased early 915 with the 3.6, but at the same time it had never been opened up so it probably had quite some wear on it anyway. Now I'm running the Alum cased 915 from a later model, good to about 70mph in 2nd before redline. Launches quite well also without any clutch problems (knocks on wood). I'm using the lightweight Patrick Motorsport flywheel. About the Ruf, the original one ran 3.6 0-60 in Road & Track magazine, Thom's running with the big boys now!!!!

Thanks Scott. Yes, every once in a while, I start thinking about engine stuff. I like high revs, so with a 3.6, I'm sure I'd make ground round out of my 915 in a season. Nonetheless, a 3.6 vs. a rebuilt 3.0 is always a nice sort of dilema. Fortunately, I don't have to think about it for a while - I hope...
