My home track is Mosport. 718 Clubsports can do 1:24. Lap record for street car is GT2RS with Cup 2 R tires did 1:22 for reference.

991.2 GT3 on Hoosiers I did 1:29. I have seen an incredible amateur driver on full slicks in a 991.2 Gt3 do a 1:28. No chance a Gt3 with the same driver can keep up with a 718 clubsport at Mosport.

Interesting

Trakcar and I did 1:32s in our old beater 997 RS on toyo ra1 in 2012. Second day there

I'd figure a 991 on Hoosier would be faster

That time of 1:32 for a 997rs on street tires for non-regulars at Mosport makes sense to me. Don't know your background and experience though.

My gt4 heavily modded with Hoosiers I would do 1:31.5 and a clubsport pro driver in my gt4 did a hot lap of 1:30.5 for reference.

Hard to truly know unless you put the same driver in both cars same day same track. But, I am about 1 second faster around Hallett (1.8 mile) in my GT4CS on slicks than my 991.2 GT3 on hoosier R7's. And I am about 2 seconds faster around Barber (2.3 miles) in my CS than my GT3 on R'7's. These are my personal best times and were not on the same day. But, I can guarantee you that the CS requires much less aggression to lay down a good lap. My gut says that a pro driver running CS vs. GT3 on same track same day same tires, the CS would be faster on most tracks (all except high speed tracks). The weight savings, brakes, suspension and balance of the CS are enough to overcome the power of the GT3.

Damn. Shots fired.

after reading this thread I have this question: what is the recommended number of hours of track use before rebuild on the engine and transmission for the clubsport? I would think this would make the answer to this question simple...unless money is not a factor.

kkabba

It's the same engine as in the 981 GT4 - not measured in hours but Miles/kilometres. Also engine doesn't get rebuilt, you just replace after 50,000 track miles or more so incredibly cost efficient for a race car.

A lot of noise on this thread. What is the OP's goal? Fastest car that drives itself? Or a proper racecar that gives him a good intro to the next level of performance?

The statement that a GT3 streetcar is better because it clocks faster laps really has no meaning. It's as apples to oranges as it gets.

Lastly, the question on engine lifetime in the 982 CS is practically the life of the car. There is no timeout on either the engine or PDK box, they are street components and will last.

Confused about the LOL, but a blown 991.2 GT3 4.0 engine to replace with labour and tax will be around $100k. I know of 2 instances that happened on track. Yes warranty covers unless money shift.

And if you don't have a trailer and need "arrive and drive" services and also wish to have track support for making real time adjustments to wheel swaps, alignment, suspension/shocks setup, pressures, data analysis etc, then it will add material incremental cost to your w/end DE.

I just saw the bill from the dealership on a 991.2 GT3 4.0 engine (engine blew going down interstate). $37k was the total. Under warranty. Frankly, I am not sure if the $37k included labor, but I think it did. Regardless, no where near $100k.

kkabba

Although I have not seen an invoice for a 991 4.0 Gt3 engine replacement including labour and tax, and have gone with what both my track buddies said was the cost to repair of $120k Canadian ($90k US so I rounded), I have an invoice for a 997rs engine replacement and it was $80k US so your $40k figure on a newer engine seems light.

But again, if you have an invoice to confirm amount then I stand corrected.

GT3 is great ... but if you are going dedicated track car, why not go all the way ?

Always wanted to try a radical. Maybe one day

I’ve logged about 20 days in our 718 Clubsport so far and here are my thoughts:

I’ll never track another street car again

Running gear on the car is virtually indestructible

Replacing the Hemp doors or spoiler are big $$$$

Slicks fall off a bit faster than MPSC 2 and are a bit spendy, but the grip is immense

Motorsport ABS / Brakes are a real treat

Car is EASY to support all on your own. As easy as a street car would be

Have fun. Did I mention I’d never track a street car again?

Good question. Goal is to have a proper racecar that gives me good intro to next level of performance. I will be working with a pro coach to set up the car and improve my driving. Safety is also a consideration as a true factory race car is clearly safer than a street car with a half cage.

Finally lap times are not super important but from my research I think I would be 1.5-3 seconds faster in the 718 at some of the big tracks like VIR than in my Gt3 on Hoosiers. I don’t want something that is so fast that It is not fun at DE’s with a mix of cars (ie 991.2 cup car)
