3.6 Varioram Conversion Performance Specs?

[spsfiend]

I was hoping someone might be able to tell me what the 0-60 and quarter mile times are for an early 911 with the 3.6 varioram upgrade are? Or point me in the right direction? Considering the upgrade on my 87 911 but am trying to find out what the performance gain numbers are.

Thanks so much!!

I would look up the 993 numbers for the VR year and take that as a guideline. 0-60 likely will be better on the earlier car with this engine due to gear ratio and lighter weight. Just a thought. I am sure there are people chiming in that have 0-60 and 1/4 mile times measured with the stop watch or their accelerometer gizmos!

just do it and drive man...

BUMP - Anyone else with some input?

[Steve W]

I don't think anyone has dragged their car to get 0-60 or 1/4 mi times, but based on my butt timer, I'd guess 0-60 anywhere from 4.1 to 4.5 sec and 1/4 in 12.0 to 12.6 seconds. Your results will vary depending on gear ratios and how much your car weighs.

I have driven his car, I am not a 1/4 mile guy but I suspect Steve W is correct. The 0-60 numbers seem about right from 'feel'.

I have a 3.8 in my '87 with stock ratios but slightly larger tires. Have not done the 0-60 in any scientific way but the difference from the stock 3.2 is "significant."

[Randy W]

Between 4 and 4.5 sec depending on how much clutch you want after.

Nobody have a G-tech or other accelerometer and can run this?

Thanks for the feedback guys!

I am trying to decide whether to pony up the $ and do the conversion or to just buy a 993... What a difficult decision?!?!?!?!

So I figure if I can get some specs on the a 3.6 in an older 911 body it may sway things.

I am also trying to figure out if it may be worth going from a 3.2 to like a 3.4 or 3.5?

$/ increased HP ratio is pretty steep...

[aigel]

0-60 times are one thing, track times another. The 993 will have better brakes and suspension on top of the added power. It will be heavier, but that can be remedied if you start taking things out.

I would lean towards hot rodding the 3.2 or getting a 993 over a 3.6 transplant.

I've had both, and I still have the 87, so the bias may be obvious... However, objectively speaking the 993 is a better car all the way around (SAI and ODBII issues excluded, and I did have some trouble there). The topic has been beaten to death elsewhere, but if your only objective is performance on the track, sell the classic 911 and get a 993. If you want a unique car that is "yours" and also is impressively fast, do the 3.6 transplant with a varioram engine.

Well said CB. There is something about a classic car that has modern power.

The times I quoted were for a 2300 lb car with a late 915, so an '87 will not be quite as quick.

An early 911 with flares, ducktail, bigger brakes and suspension and 3.6 VR is nothing like a 993. They are totally different animals in experience and sensations. Both can be equally as fast but they do the job quite differently. Best to ride in each to get an idea before making decision.

[midnight911]

when i blew up my 3.2, i contemplated between 3.4 high comp twin plug and 3.6. The cost projections for both were about the same, or 3.4 being on a little higher side. In a longer term, 3.6 is stock and i figured cheaper. yes, i'm a cheapo.
i would love to have 993 also. Do a GT2 body kit if you get it.
i'm jealous you have these options to consider.
whatever you do, continue investing in your driving skills as that is THE factor to get the car going. If you are just looking for a car that goes fast, 10+ yr old porsche is not the answer.

[efhughes3]

The thing about a built 3.4 from a 3.2 is that it is indeed probably as expensive as a conversion, but you start out with a new motor. 3.6 conversions are not free, and unless you know the motor going in, there will always be an unknown quantity to it.

This is a vid from a 993 with 320bhp and torque to match, he catches my blue carerra with 3.6 non vram (276 bhp) at about 1.39, mines the car with the black duck.

It was my first trackday so was slow in the corners but you can clearly see how much it pulls away on the straights. I've now had it remapped to 296 bhp so is even quicker, rarely bump into much on the road as quick.

This is a vid from the same day I think of an SC with a 3.6 chasing a 997, they are plenty fast if thats what you are looking for.

I say do it - you wont regret it.

Two data points:

Car 1 2200 lbs, ~310 hp VRam, 915, 265 V710 tires. 3.7 to 60 on the best launches G-tech.

2nd car 2400 lbs, ~295 hp Vram, G50, 3.9 to 60 best launches. 1/4 was generally 12.5- 12.7 @ 115-117.

Pete,
How about the water cooled early 911 monster? Any data points on that?
cheers,

Doug

Doug,

I've simulated the car so I know roughly what to expect, but I have not done any instrumented runs yet. I'll find out soon...
