Wonder why they stayed with the 3.8 and not the 4.0?

Because the x51 is a better lighter unit which makes power to red line.

A shame the road going car did not get the x51 engine though.

Not road legal so all the faff getting it to the track and storage etc etc..... As Chris has said, few choice mods to a road car is an easier option

Absolutely.

Will also be running PFC rotors and MR brake pads. Just as on the CS

So the 981 with the above upgrade ‘maybe’ a better way to go than a 718? No gpf !
How much does the engine upgrade cost?

This is nonsense. They didn't change it because there was no reason to from a cost perspective. The 981 and 718 Clubsport can run in the same series and the 3.8 is a known, reliable entity that can make the power. The Clubsport is mainly built for racing and the cars run under BOP. It doesn't mean that they won't use the 4.0 in future or that the 3.8 is "better".

Weight was a massive issue in early 981 CS race cars, hence they bought out a weight reduction pack which made a massive difference to the car, putting the 4.0 would reverse that weight problem which plagued early cars.

Also, the 4.0 engine wasn't ready/finalised before the cars needed to delivered at the end of 2018/beginning of 2019...

I would suggest that we find out the comparative weights of the 981 3.8 engine and the new 4.0l ...

If anybody has hard information it will be David, any less a reply appears to be unfounded argument ... and hot air.

I am very happy to tune the engine I have and would observe that by comparison to the Gen2 3.8, the 4.0 at the time when the 718 Clubsport was completely untested in the hands of users.

In addition, Porsche had an extra 40bhp in their pocket with the tried and tested X51 ...

Please all remember, the whole concept of the GT4 Clubsport series is that all the racing components are unlifed ... irrespective of which it remains a fairly expensive option for mere mortals.

Summary of Chris' build from the other thread, as detailed by David....

Porsche911R said:
they sort of are. If hope it's ok to post as this is all what Chris car has and his stages.

1st off as the GT4 is fixed at the rear and lacking a set up is the Manthey stage 1 road kit.


This allows a basic track set up.

Chris then wanted to swap out the disks to ST and that's been great as they just don't wear out.


after that he wanted a proper Manthey set up so went for their GT4 full racing 3 way kit with a ring set up geo.
this car does not dive or roll, and it must also save tyre wear as the GT4 is too soft oem and does wear edges badly.


A few CUP race car parts with monballs were added to reduce play and add feel and also allow for caster adjustments.


and last the engine mods to 430 HP / 345 LBF-FT with a new M and M big bore full system and Jens magic on the RR.



I think some BBS Fi-R wheels next and some bbi wing uprights would finish it off very nice :-) lol

So yes pretty much off the shelf parts, put picked well and fitted by experts.
Chris has since added the BBS Fi-R wheels
