Yellow Ultima on M23

[knight]

Northbound at 11-30 this morning, nice sight to brighten up a dull morning

Probably me and that nice GTWayne going up to Brands for a noise check and look see at general testing.

Delightfull little trip out with a quiet new exhaust

And just how quiet is your car?

Aspiring to be elevated to 'Very nice' status as you are Rusti
Thanks to you I am now going to have to re evaluate my thinking on y e l l o w Ultimas ( ones with an LS7 motor installed any how ).

Sounds quiet and "mellow" but unfortunately not quite as quiet as it sounds!!

99db at 4400rpm and I'm quessing about 102 at the 5250rpm needed for a proper sound test.

Add-on silencers still going to have to be made for Goodwood etc.

The LS 7 is miles quieter because the dreaded SBC Anvil Chorus isn't clanking its merry tune .......

Hi Stuart, how does performance compare with the SBC?

[Rusti Evo]

Howdy Gary,

Difficult to compare the two as they are so different. Start it up, drive it away, just like a proper car - gasp...... All the "colourful" SBC traits have vanished Definitely lives up to its reputation, smooth,smooth,smooth.........but with shed-loads of power - awesome.

The motor has only done a couple of hundred miles and I'm determined to treat it with maximum possible respect until it's broken in. This is going to be one well cared for engine!

Better stop doing track days then!
