How can I increase my 458 Ferrari HP?

Saving 10 lbs can be done with a good 19/20 combo. 20.5 for fronts and 22.5 for rears. Heck the GS1-R in a 19/20 combo will save 17 lbs over the forged star wheels. But that's about as good as it gets, and few if any, can match that - not even the Enkei RPF-1 is that light. It might be possible, but looking at the wheel design, I doubt it. Multispoke wheels like those are rarely very light compared to a race style split spoke wheels such as the GS1-R or an A-beam wheel like the Superforgiata.

Yeah, without a scale or very specific info, we'll have to wait and see. But depending on the starting weight, 2-3 lbs per wheel seems doable.

Don't know your BMI but perhaps try going on a strict diet for starters ..it will save you money and make you fitter and healthier and yes, faster!

Ok it won't give you more HP,also run with minimum fuel ,just enough to get to cars n coffee and do a few burnouts with those pesky orientals.

 

Thanks Ray! You are right, they are darn light! I just calculated it, my Speciale wheels vs stock make it a total of 16 lbs lighter. That's a lot in the wheel world. Pic of the car

Wonder how much quicker this makes the car

 

Sounds like an F8 is just what the doctor ordered.

458 is plenty fast enough for me. Scares me sometimes.

 

This is an interesting question. When I think of any proper naturally aspirated car I personally would not bother with tuning it to get more hp or tq out of it as most people said the most you could probably get is another 50 to maybe 100hp out of it. I have only considered it personally when dealing with twin-turbo supercars or cars that are considered "borderline exotic supercars" such as an AMG GTS. I already feel the kick in those types of cars and if I wanted to have some serious fun probably look at cranking them up another 200hp although it would cost some good $$$$.

In any case, if you are looking to make changes consider things that are easily reversible as these cars tend to resell better in stock condition or with only cosmetic changes as opposed to major tuning. Besides wouldn't a lot of the tuning void the warranty... Just my thoughts.

Best of luck and can't wait to see what you end up doing!

 

You need fabspeed manifold, pipes without cats, and tune for this mods. Best power gains on 458. And BMC filter because it cheap.

 

May l suggest the obvious. Everyone knows if you fill your tires with ltalian air it has the same effect as increasing horsepower by at least 100 hp. But given the current virus crisus l suggest you wait until this problem is resolved.

 

Looks like their website is actually here: https://vossenwheels.com/engineering/

However, I'm not sure which wheel you've got there on your 458.

Also, I don't see much in the way of weights for the different wheels listed on the website.

Can you provide a photo showing the front and rear tires also? That will show on the side wall what size the rims are.

In my experience, if you haven't actually weighed the rims yourself - or have very specific details - it's very easy to think you are buying a lighter wheel and actually end up with a heavier one. I'm not saying the Vossen wheels aren't high quality. However, even companies that have very light forged wheels, sometimes also sell cast and flow formed wheels, which often weigh more.

Anyway, just curious.

Ray

 

Ok, I think I found your wheels:

https://vossenwheels.com/wheel/vps-305t

If you can post the tire info on the side of the front and also rear tires, I can probably figure out which rim you have specifically.

From the pictures, the rears almost look like 22's, but it could be the angle.

As far as weights, I'll email the company and see if they can provide some details. I think it would be interesting to know, because wheel weigh is often an area which really can affect performance.

Ray

 

Sounds interesting. I was thinking that size too. Definitely does not look like a 19/20 combo, but more like a 21/22 combo. If the latter is the case, there is in fact a lot of performance to be had by both reducing the weight, which could be significant with the right wheels, as well as reducing the diameter. My guess is that if it is the 21/22 combo, tyres are 255/30R21 and 335/25R22 PZeros. All this mass and increased diameter will subtract significantly in terms of performance.

If I was in your shoes, and the 458 was something to stick with rather than a 488 or the like, this is what I'd do. A power increase with a healthy diet.

Capristo manifolds
Akrapovic ti 200 cell cats
Akrapovic ti exhaust system
Novitec Piggyback
Braille I48CX battery
Capristo CF airbox
Capristo CFside engine compartment covers
Capristo CF rear diffuser
Forgeline GS1-R wheels 9x20 ET 40 11x20 ET 54
Michelin PS4S 265/30R20 - 325/30R20 There's about 18-20 lbs to be had on the tyres alone, not including wheel weight savings.
Speciale springs

If you don't have CF seats, get them. There's about 50kg to be had there over full electric seats and about 30 kg to be had over stock seats.

Now all this is nice and cool, but it's expensive. Fact is that you can do all this, and a 488 will still be faster and cheaper. Imagine selling the 458 for a 488 and giving that 488 the same treatment.

Such a treatment would look a bit like this.

Akrapovic ti exhaust
Akrapovic sport cats
Novitec N-Tronic piggy
Braille I48CX battery
Capristo CF airbox + lock cover
Capristo CF side engine compartment covers
Capristo CF rear diffuser
Forgeline GS1-R wheels 9x20 ET 40 11x20 ET 35
Michelin MPS4S 255/35R20 - 315/30R20
Novitec or Pista springs
CF seats

Add a bit of chassis dialing in with better camber and toe settings along with a small drop, to get it more neutral and more precise, and that 488 could probably outrun both the 720S and Pista if they went head to head.

I'm just trying to illustrate how far you actually need to take the 458 to get it anywhere near the more modern variants.

 

Best option if you want to keep the 458 but much cheaper to upgrade to the 488.

https://www.undergroundracing.com/index.php/extensions/ferrari-458-tt

 

Indeed very fast. But there's more to it. It's expensive as you can see. 70 grand for stage 1. Like I touched upon earlier with the turbo build, there's another caveat, which is the devaluation. Once you're done with that car, nobody will touch it. It will be worth much less than a non-turboed 458 so that has to be factored into the cost as well.

There's a guy in my neck of the woods, whom have done quite a bit of the Underground Racing upgrades to his cars - in part because he helps them develop their systems. He was a front runner on their old Gallardo setup and one of the first to build a twin turbo Gallardo. He did the 458 setup, and that came with a few issues. The biggest issues were of course the driveline. It destroyed both the transmission and drive shafts. The car is simply not built for it, and while it might be fun, it WILL decrease longevity quite a bit, and there will be a lot of running costs associated with it. My take on it is this. Get a Pista and get a Novi piggy, within 24 months you'll be money ahead, and you have probably gotten much more seattime in the Pista.

 

From searching around google, it seems like Vossen wheels in the 19/20 inch size might weigh as much as 25 lbs. - but I could be off a bit. If they are larger, such as 22, then the weight could be more.

I guess we'll have to wait to hear back from Warren.

Ray

 

I used to always drive my 458 around town with only half a tank of gas... that shaves off about 60 or 70 lbs

Ray

 

Why not go with a set of Speciale wheels. 18 lbs each on the fronts 22 on the rears! You can find used sets for less.

 

18 lbs is getting down there all right!

Ray

 

18 lbs? No way that's correct. HRE, OZ and Forgeline can't get that low. I'm well aware that Exoticar Auto claimed that, but I don't believe that until I see it. That weight is next to impossible for a 9x20 alloy wheel. Another thing that does not add up, is the fact that there's 4 lbs difference for a mere 3" extra wheel barrel. Look at the other forged wheels, such as the SA wheel and the stock 458 forged wheel. Those add 2 lbs for that 3" of barrel- We should be able to deduct from that, that the weight of the Speciale set is 20 lbs front and 22 rear. An OZ Superforgiata has a mere 1.5 lbs of difference for an entire 3½" of barrel. I believe the rear is 22, but I think the actual front wheel weight is more like 20 lbs. 18 simply does not add up.

 

For a 19" rim, 18 is certainly within reason.

Refer to this thread:

https://www.ferrarichat.com/forum/threads/ferrari-458-factory-wheel-weight-comparison.525346/

I have a set of 17 x 7.5 Volk wheels from 2000 sitting right here in my living room and they are only 15.2 lbs. 18 lbs for Speciale wheels is plenty doable.

Ideally, we'd need to see a Speciale wheel sitting on a scale.

Ray

 

True Ray, and I have no issues believing that a 19" wheel can weigh 18 lbs, but we're talking a 9x20, not a 19". The OZ 19" is 18.4 lbs.
I'm well aware of that thread, and that's why I mentioned Exoticar. But despite their claims, I don't think that adds up. Something's off. It's not that I don't think wheels can be light, I know they can. I used to have a set of Enkei RPF1 in 9x18 which were just around 17 lbs. But that's one of the lightest non-magnesium wheels ever produced in a version which had a very low weight limit, I believe ti was rated for like 400-450 kg. By comparison, according to their website, their 7.5x17 is 15.25, it is a very light design.

A weight of a 5 spoke style 9x20" wheel of 18 lbs as well as it being 4 lbs lighter than the matching rear, is something I will only believe if I see it in person. It simply does not add up.

 

I think seeing a wheel sitting on a scale would be what we really need here. I believe Exoticar has some for sale on ebay, so maybe they would be kind enough to snap a photo.

With the Carbon Fiber wheels I bought for my R1, getting exact wheel weights proved to be difficult. It wasn't until I actually had them here that I was able to put them on a hanging scale and get an accurate weight.

At the end of the day, it's all speculation until someone takes a wheel and places it on an accurate scale.

Ray

 

OEM wheel weights

Here ya go. We didn't take pictures of the wheels on the scale but I have no reason to fudge the #s.

https://www.ferrarichat.com/forum/threads/ferrari-458-factory-wheel-weight-comparison.525346/

 

Indeed. No doubt the Speciale wheels are light, and a nice wheel, I just think it's a bold claim and I can't see it being that light. If I had a Speciale wheel sitting, I could have taken it to my sister in law. She has a high capacity Ohaus analytical lab scale that weighs up to 35 kg within 0.001 grams. Used it to weight CCST brake discs two weeks ago. Every garage should have one of those lol

 

I put a 15lb dumbbell on the scale and it was dead on 15.
