If you are stage 3, then you should be around 360hp? and 165kg out of a manual should put you around 1250kg.

Not too far off with some sticky tyres :happy2:

I'd be surprised if you didn't knock at least 3 seconds off with all that weight out of the car.

5 seconds would be on a perfect lap, with a few brave pills. :laugh:

The braille is just 31Ah, the Odyssey I want to buy has 45Ah wich is a little better but also 12.5Kg as compared to 9.5Kg for the Braille. However, due to my audio system, I have to use a deepcycle battery that can be fully recharged from 0. Hurdy, my car had 1664Kg with me and 55% gas (the audio system only is about 150 to 180Kg). So with the 165Kg out of the car I will be in the region of 1500Kg (with me inside) ! In the list above, I haven't deducted the speakers + the front doors (+10-15Kg per door as compared to OEM due to massive fiberglass speaker panels) + the amplifiers + rack (about 50Kg ). I only put out the subwoofer from the system !

^^^^ :surprised:^^^^^^

That is one hefty car Fuscobal.

Or should I say was :smiley:

It doesn't take much sound equipment in a car to ramp up the weight.

Yes Hurdy, I know. Unfortunately it's sooo hard for me to let go my audio system as sound is for a passion as big as car's performance. This sound system also brought me 2 times the 3rd place in Europe at sound quality in 2006 and 2007 and it got even better now !

That's very ok for this dimension.



ps:
swap for home hifi - even heavier, but it doesn't affect your lap times   :signLOL:

(I do it this way: Linn LP12/Pass PearlOno/Pass Aleph/Odeon horn speakers)

Nice system Bruce. Congrats, didn't know you're into this !  :drinking:

My car system says :

- Clarion DRZ 9255 Head Unit (made with McIntosh) > this unit + the voltage converter weigh in at max 1Kg more than the OEM unit they replaced
- Audison VRX 4.300, 1.500 and 2.150 (these 3 have 23.6Kg + another around 30Kg for the lower and upper MDF bords, cables, distributors...). We are talking about 55Kg wich sit exactly on top of the rear wheels. This have the benefit of keeping the rear planted but I don't know if this benefit is smaller or bigger than just removing those 55Kg from the car
- 2 x Micro Precision 7series / door (the doors are heavily damped and the 2 speaker are sitting on a massive 2cm fiberglass panel > we are talking of some 7-10Kg/door more than OEM)
- Scan-Speak revelator 12M midrange installed on the dashboard (these don't count for more than 1Kg in total)
- Scan-Speak revelator 700001 tweeters (these also don't count for more than 1Kg in total)
- Brax Matrix 10.1 subwoofer + enclosure > 34.5Kg (this can be taken off and installed back in if needed)
- Power Cell 3000 > 27Kg (don't really need this much current for my listening levels so this is where I'll lose weight first)

The small room (computer room) audio system :

Computer > Benchmark DAC 1 > Vincent 226 amp > Chario Academy Millenium 2 bookshelfs

The big room audio system :

EMM Labs CDSAse > Pass Labs XP10 > Pass Labs X250.5 > Usher BE-10

My LP12 is 20 years old.  :smiley:
Classic Ittok LVIII Mk.2 arm, Troika MC (rebuilt). DIY CNC-built Keal chassis.

Have an Linn Axis with Akito as well and a Rega Planar 2 with RB300.
Also some good old amps like my Cyrus One, Linn LK1 preamp with Dirak
and two LK2/60 power amps (all are heavily modded).

You see I like Brit-Fi.  :evilgrin:

Some years ago I was more on the audio forums.

Most of it was bought secondhand, the 'old Hifi' is worth roughly what I paid, which makes buying justifiable. Not 'cheap' I'll grant you, but a 30 year passion  :smiley:
