The LR Super 48 comes with a T31 turbine I believe. It's a 50 trim t3/t4, and I'd be willing to bet my life was built off a Precision SC series turbo (most likely SC50).

hey, dont hate to so say it, I have and will continue to learn from people that have been there and done that, sooooooo..............it looks like a bigger turbo, head and intake.....I can do that.

Updating the head at this stage is a waste of money a good turbo and proper mapping will get you your goal without touching the head .....

We used to race one in GT3 pca @ 455 whp, the wing made a difference but traction was good with the exception of 1st and 2nd......

One Thing I have learned with reference to weelspn In a 951, my brothers, Is that wheel hp matters not(as much), neither does peak torque.
Instead, the rpm range of peak torque matters most to wheelspn.
The 951 likes to make peak torque in a certain wndow - NO MATTER WHAT TURBO/HEAD/CAM/EXHAUST.
This is NOT TO SAY fastest.....just most weelspin

Bore /stroke ratios is in part responsible for your TQ /Hp curve...
A peaky power curve will also lead to excessive wheelspin Something that makes the quick spool peaky guys feel fast , but it is not ....

Surely you can move the power and tq curve around a bit with different spec parts and profiles? Also older style suspension much less likely to be able to prevent wheelspin. I am not alone in experiencing a much greater lack of wheelspin with KW suspension and a proper LSD. (See pic's of new Motorsport LSD's in new thread going at the moment; ART!) I really have to try and spin the wheels if I wanted to do this (I don't). Granted, with a lighter racecar on 'only' R-spec tyres it may be more of an issue. I say 'only' as I am a fan of Toyo RA-1's but they're not a slick.

T04b 48lb wheel ...forget if its v or h trim. Hotside is a #8 with a stg 3 wheel. ...could be wrong but I'm pretty sure thats what it is. Dave Lindsey isn't a fan of 50 trims for some reason.

I am saying that the 951, because of its design, will always make the sweetest torque in one area.
And I would say that you want to reach max boost at about 3700 rpm to achieve this. This is with perfect tune, modern turbo and hardware biased for torque.
I base this merely on 1000's of datalogs and 100's of dyno runs and the torque peak figure achieved, ultimately, in my sig.

also interesting that you have very little wheels spin , then your setup is very good , yes Kw is a good suspension, but not to have any wheels spin with over 400 whp/tq, is very good ..........and unusual ......
