scud weight reduction and horse power increase

doesn't underground racing do a twin turbo package?

 

Are you looking to track the car, or have more power for drag racing/straight line?

 

I believe the Capristo full system (headers, exhaust, etc) with the heat shields improve the acceleration/power quite a bit while also decreasing weight. F430GT was the expert on this but he seems to be in a bit of a pickle at the moment. Good luck!

I can't help you with (reliable) insane power gains, but there are ways to reduce weight on the Scud without losing capability or drivability.

Yeah - if you really want it fast fast - then UGR for a good 45-60k can make it blisteringly quick.
But it's already a pretty fast car

 

Tool kit & useless puncture repair kit will save you a kew KG

 

I think that changing the wheels and tires to a much lighter set up will be the most noticeable weigh saving measure that you can do. It will change the way the car acts under acceleration, deceleration and cornering. Any time you can save weight on an un-sprung rotational mass the effects are felt much more so than changing weight on a sprung mass (supported by the body of the car).

 

Some obvious weight saving measures, whit my estimate of total weight saved (please correct me of wrong):

Lithium ion battery (-/- 10 kg)
Full AM exhaust (-/- 15 kg)
Wheels: BBS F1 (or RI-D; which is even lighter) (-/- 8 kg)
Radio/Speaker delete (-/- 8 kg)

Total weight saved: +/- 40kg, maybe 50kg max.

You can save some more weight by buying the CF Scud parts (diffuser, sills, engine compartment, rear deck, boot lid) but weight savings will be limited and expensive.

 

conventional wisdom: 8kg wheels = 16kg body

 

This has been my project for the last 18 months.
Car started at 1360kg standard on empty fuel tanks and washer bottle. Used race scales for accurate measurements.
It is now 1300kg and as a result of the full Capristo exhaust system has a claimed extra 40hp and 60nm of torque. My goal was to not diminish the comfort and usability of the standard car and keep it looking pretty standard.

It's a law of diminishing returns and exponential increase in dollars spent the further you go into it.

I have found the biggest gains and bang for your buck as follows:

Lithium race battery- - about $3k with charger. Weight 4.2 kg versus 21kg lump Ferrari used in the 2008 cars. Some later cars used an ultima red which weighed circa 15kg

Full Capristo exhaust from manifolds to titanium exhaust tips- weight saved 24kg

BBS FI wheels- look great and save 8kg. They are also wider and allow bigger tyre fitment. People forget that the larger tyres weigh more and your weight saving (depending on tyre choice) is largely negated. I went for Pirelli Corsa R tyres and overall weight loss was about 3.5 Kg from memory.

All the original optional carbon fibre equipment offered by Ferrari. You can spend huge dollars to get the rear engine cover, diffuser, side skirts and a few other odds and ends. Weight saving is about 12 kgs from memory.

Then I had some customer carbon fibre front and rear bars and a front boot lid made in carbon fibre. Not a lot of weight to be saved as the originals are very light anyway. By the time you make the custom stuff fit well and look pretty enough there isn't much weight saved.

I put weight back in by adding the 4 point seat belts with appropriate mounting brackets. Probably 5kg at most.

Last things I have done are have custom foot plates in carbon fibre made to replace the aluminium checker plate which I think looks ugly. Maybe save 1.5 kg, haven't weighed them yet.

Final weigh in soon should see it under 1300kg by a small amount.

You could save another 10-15kg by going to full race buckets and ditching the standard seats. That would compromise comfort and usability too much for my liking. Ditching the air conditioning and using 430 Challenge doors and windows would bring huge savings. Don't recommend this for safety reasons on a road car.

That's my experience so far.

 

any tested batteries other than the optima red top to use on a scuderia?

 

Yes, a member has used one of the Braille Li-Ion batteries without any problems.

 

any thoughts about the porsche Li-ion batteries

 

Standard Fiamm- 21kg
Optima Redtop- 15kg
Braille Lithium- 4.2kg

I've been using the Braille ML30 Lithium battery for over 12 months now without a single issue.

thanks for the replies. Appreciate your help

 

What is the part no for the optima red top battery

 

I'm 5 foot 7 inches and weigh 182 pounds so I know what the cheapest option is

 

A diet....
