Hi,

Just brought a second hand Monaro 2004 LS1. Drives brilliantly and could not be happier! Haven't used the radio once since buying it!

My only issue is with power! Like i do with all my cars i took it down to SRR to make sure every thing is ok and to get an idea of bhp and torque.
The spec engine wise is Wortec Focus pack from Monkfish.

It made 368bhp at the flywheel and 297 at the wheels.

Having a look at Monkfish website this seems to be nearly 50 bhp down on what they say the focus pack should produce.

The fuelling etc is spot on and it pulls like a train!

The 14.9 mpg is well worth it!

I took the air filter out and it was fairly dirty so have ordered a new replacement. Will also order new plugs whilst I'm at it.

For the work its had, headers, sports cats etc from the focus pack i was just expecting a lot more! This is the whole point of putting my cars on the rolling road to make sure they are running as they are supposed to! If i had spent the £3699 for the focus pack i would be a little pissed!

I m just looking at the original invoice from Monkfish and the price was £3,699 back in 2008 when the work was carried out. Have the changed the spec of the pack at all does any one know?

New plugs, New 8mm Magnecore leads and new air filter ordered. Will see how that works out! Will get my name on the list for the SRR day next month and re run it!

Just a quick update.

Had plugs, leads and air filter changed. The difference is fairly impressive! WIll be good to see the results on the dyno in October.

Also swapped the 'quiet' exhaust option on the Wortec exhaust to the loud option… my good god its loud!! not sure its to my taste but for the time being its quite amusing.

Cheers for the help
