As above. Anyone got any suggestions?
Was thinking about either retrofitting sports chrono or fitting a lightweight flywheel. Car is not a daily driver.
I want it to feel a little more alive.

When we're the spark plugs last changed? I felt the car pulled better after I had mine replaced. I guess the other option is a remap to adjust the power and torque so it increases further down the bottom end.

Out of interest, what makes you feel its not that alive /responsive? Have you had faster cars in the past?

I've not had faster cars in the past no.
Spark plugs were changed at last major service 1000 miles ago.
I'd just like it to feel a little more responsive. My indi is looking into remap options for me.

Before spending lots of money try fitting a sprint booster , this fools the throttle into thinking your driving much more aggresivly than you are , the old style has 3 settings the new has multi settings . this worked really well on my 997.1 tip when I had it and is not an expensive mod to do. it yours a tip car or manual

I would have thought that in order to improve throttle response, you'll need to reduce rotating mass around the engine with a lightweight crank pulley and a lightweight flywheel, especially the latter. And an improved airbox and free flow manifold with sports cat to improve the breathing. And maybe bigger injectors. All followed by a decent custom remap to make the most of the changes. How far do you want to go?

Some great advice here.
I think I'd get the fault codes read first.
Are the coil packs new?

Sprintbooster, under drive pully first options.
Lwfw and balancing starts to get v pricey.
N/a 997 not normally noted for poor or unenthusiastic throttle response, so worth getting an indy to check it over perhaps.

Fit a solid flywheel. It makes a massive difference to response.

I don’t know if it can be retro fitted, but the sport mode you get with the sports chrono package makes a massive difference to throttle response.

I beleive it can but I understand not the stopwatch part. If fitted then you can go the DSC route to alter both throttle response and suspension set-up. Obviously you need PASM aswell!

Throttle response ..

DSC or sports chrono upgrade .. no clock .. it's just throttle response .. either are imho what you are after .

I have had sports mode retrofitted to my 997.2 C2S and it has completely transformed the car. Best upgrade I have ever done to a car. In sport mode or sport plus the car now comes alive. 😀😀😀

Mine's a manual. Does a sprint booster work on a manual car?

Any idea as to cost including fitting?

If you use the OEM GT3 RS4.0 clutch plate it isn't an issue.

Here you go - get a pair of these race boots. Same effect as a sprint booster.

They do sprint boosters for manual and auto just be sure you buy the correct one. cost is under £200 and fitting is a 10 min job to try it , and if happy then a little longer to route the cable and controller to where you want them .

this is worth a read
https://www.6speedonline.com/forums/997/196447-installed-sprint-booster-my-997-c2-instructions-w-pics.html

There will always be those that say a sprint boosters only the same as having a heavy foot and stamping on the go button all the time , but in reality we dont drive like that on normal roads so we need a devise that fools the car into thinking your doing that when your actually driving with regular foot pressure . who actually stamps on the go pedal all the time.
