SVA LS7 GTR emmissions + weights

[GTR One]

After a long absence of too long the GTR finally passed the SVA today!

Took some serious exhaust sealing efforts in the run up to get the lambda reading to the 0.97 - 1.03 level required! But once there, HC was 11 ppm (vs pass level of 200 ppm) and CO was .01% (vs pass level of .30%) So massively within the limits I wonder if it would pass without the cat?!

Out of interest the final dry weight (once my portly mass and fuel are deducted) came out at a shade under 910kgs, which I didn't think was bad!

Hopefully make it to the Exeter show..Is anyone else going?

I plan to go down but most likely in my Dakar.
May then go down into Cornwall for a few days from there.

Where are you gonna put the number plate?

[suntiger1965]

you cant use the black sun strip on the windscreen as you are not allowed white letters on a black background./.

car looks fantastic, especially without a front number plate.

How did you manage to wait from June to now before re-submitting your car for SVA, werent you driven by curiosity, or testosterone fuelled salivation even ?

FWIW, no, it's impossible to meet the HC/CO target's at Lambda 1 without a CAT, to meed the CO/HC target's you would have to run the engine somewhat leaner, and thus fail the 0.97-1.03 Lambda target.

A very nice car! The colour has certain looks with the old Sauber group C race cars. Post some more photos please!!!

TBH I wouldn't go much on the SVA's weight. When I had mine corner weighted it differed some what from the SVA weight.

There scales where built for 30 Ton trucks so they just arn't that accute for our leight weight cars.....
