12.69 i think was recorded by Chris at Blue Power Racing Developments in his BA XR8 ute (auto). Intake, exhaust, edit, probably underdrives....
I think last friday he did a 12.74 and blew the auto just after 200metres. It's going to have the engine opened and played with now... so in my opinion it will be the first 'properly opened' XR8.

Your on the money Parawolf, But I think Chris is pretty determent to get a 11sec 1/4 before he opens it up. Chris has a few more tricks up his sleave that he want to try out before he cracks it open. EDIT: The Holden girls are going to hate Chris when he gets his 11 sec pass in an unopen Boss 260 |

There are definatly some good times ahead. The 260/290 boys are starting to peg back some of the 5yr head start the LS1 boys had, however a way to go yet. Makes for VERY intresting watching. Keep it up guys, on both sides of the fence.

That's right we are yet to see the Boss's FULL potential, the LS1 guy's had a few yr's up their sleves, so we are not to far behind in comparrison.

LS1's have 'weak' valve springs I think it was... so to maintain reliability it was deemed at some stage 'okay' to replace the valve springs because it doesn't go "into" the guts of the engine itself...

Id like to see unopened include rockercovers, Trans, Diff and interior, most quick LS1's are stripped out virtual racecars.

To me valve springs changed = opened...
Yes it may not improive performance on its own but it allows more revs reliably which can enable more performance. To me its NO different to running a steel crank, H-beams and forged pistons, claiming that its for reliability only and running as unopened.

This has become a big agrument with the Ls1 valve springs and have to agree that anything in a engine comes in contact with oil and is changed deems a opened engine. Geez we could turn around and change cams in the boss motors and say it's unopened as we just took the rocker cover off just like the ls1 boys..

We don't have to be like the LS1 guys. If we stick to our guns, they may re-classify their terms. Unopened has to mean what it says. I'm thinking the engine is either stock, stock with bolt ons, worked or forced induced.

I agree with everyone about the valve springs its opened but under there LS1 rules they are not...
so what do we do.... . Why dont we just do the same, if your wanting to do it, just change them valve springs. if we are going to try compete at least we should have a level playing field to start. Just added a Poll to the top of this page, its open for 30 days. What do you think? change or no change give us your thoughts?

Okay I figure level playing field is fine - replaced springs is either opened in both cases, or unopened in both.
However do the BOSS engines require spring replacements? For example the LS1s _NEED_ replacement, but do the boss engines need it to run a 13.0? or to run 12.5? or faster? Or is it a reliability thing. Personally I figure springs as it is definatively a reliability thing only as it does not affect power, but it allows for more power to be generated. I call it unopened.

Every LS1 powered vechile that i have seen that has run a decent number un-opened and opened have been stripped out.They even go to the extent of taking the boot mat and all the door trims ect................... : I would be interested to see a BOSS powered vechile with all the mods,stripped like the LS1 clowns. :
