Performance mods for 458

Well if it pulls well up to the 170s, I guess I can live with it. I am still getting one this year then. What a relief.

As far as your needs for speed. I can totally understand that and don't really care how fast you were going or where. But I think a bugatti supersport will not disappoint.

 

Better keep the Scud!

 

Wow. Never been in those stratospheric levels with my F458! How fast were you going on the 6th to 7th shift?

 

You answered your own question, the 458 feels slow is because it got much higher refinement then the Scud. That is why fast Go-Kart feels scary fast.

HP requirement is exponential at really high speed. If you want to feel the rush at the top end, you need at least 800 hp. 570 from the 458 is not going to do it. 1000 hp feels awesome at +160 mph.

 

I think you are approaching this respectfully, so no need to qualify (at least for me). I do suspect it is "seat of the pants" given the driving characteristics of the two cars. A real comparison if you still have access to a Scud and your track permits, is a side by side run. Should take all the mystery out of the objective condition. As for the subjective, as has been suggested, whether it be cats or ECU, you may need to go to a blower (someone has or soon will have them available) or turbo's to get the feeling it sounds like you are looking for.

That is true on all NA motor.

It only makes a big difference on turbo engine where 93 octane allow higher boost, typically a 10% hp gain from a 10% higher boost pressure.

 

Holy smokes that must of been fun! While I know you needed more power, how stable was the chassis at those speeds? I will likely only dream of going that fast in mine.......

 

The "things coming at you fast" is an understatement at 2.5X normal freeway speeds!

 

I have done 180 mph in a very stable car, it is really not a big deal in a straight line, unless something bad happens. It is really just "things coming at you fast".

 

My expectations for 458 was higher than it actually is.
I use same road in similar conditions to judge my cars like you do.
F430 and 458 spider is strangely in the same league.
I don't know what will happen after I pass 5000kms and do another oil change at which point Ferraris get faster all the time unlike Lambos.
Takes more than 35 secs to reach 180 for sure.
LP640 takes under 35 more like 33 secs.
FF takes same or less time as LP640.
Was really impressed with FF and will buy facelifted version for sure.
Aventador...now any time any moment with stretch, it gets 180 with ease...Different league.
So, like you, I am really suprised to find out there is not much difference in the top end between f430 and 458...little disappointed I would say.

 

Yes. Completely different experiences -- refined vs. raw. Maybe the forthcoming track-oriented 458 is for you.

 

Or if the track is a regular thing, consider getting a race car for the safety reasons. Hitting these speeds with these road tires in a road car is dangerous and potentially very costly if you start bending up a street 458. Why bother with the performance modifications? Just get a race car and be done with it. Here is a link, no affiliation with seller.

The dual clutch vs. single clutch alone completely changed the character of the car.

 

OK, I will not waste my money. Thank you.

 

I think, there must be something wrong with your 458.

When I drive on an empty German highway I have really fine accelaration in the 6th gear till the upper end of allowed RPM. This is around 185 mph.

Honestly spoken untill today I have never been driving higher speed than that.

Also in the 7th gear when I push throttle hard around 140 mph the accelaration is really nice. But I have no comparsion to the Scud. Some friends of mine have a Scud and have tried the 458 too and they tell, that the 458 has clear better acceleration.

I suggest to go with the car to the next Dyno. If you measure lower than 540 hp and/or lower than 510 Nm you should start a serious claim. Maybe there is something wrong with one of your cats, or the exhaust-valves, or or or ....

Have you ever thought about getting a Lamborgini Gallardo and twin turbos. I am at 1138awhp now and in the process of turning her up to 1250 whp. Talk about pull from 60 to 200 is unbelievable. With all wheel drive it puts the pwr down and goes. Something to think about if you love the pull of pwr, about 1400 crank hp.

 

Man, you and I have the same taste in cars! I have a UGR TT Gallardo, and after driving it, nothing else seems fast anymore. Hell, my FGT-TT will leave a Veyron behind from 100 mph on up....and that's when I was running only 17 psi/800 rwhp. 205mph in the Texas mile. The Underground Gallardos have broken 250 (!)

(For reference, a 458 runs about 175-180 mph in the standing mile.)

 

Yea, we do Doc! What pwr you putting down on your UGR? Those guys build some monsters!

 

1014 awhp on 93 octane/15 psi, 1250 on C16....

6 speed manual, Tilton triple disc clutch, UGR stage 3+.

 

A couple of observations:
First, the 458 is geared high thru 6th gear, whereas 7th is lower geared to achieve a 200 mph + top speed spec. That's one reason why 7th feels slower.
Second, at speeds over 160 mph max HP and drag play much greater roles; thus at 560 HP the 458 will feel slower than, say, an F12, which has 160 more peak HP. The 458 is suited for most tracks where straight away speeds are less than 160 mph or so. If you want lots of grunt beyond that go with a V12 Ferrari, or something similar.
Best.

 

I was driving at 175 mph in Italy last October and there was plenty of power left...
