There aren't many 260 campaigners that are all that hungry, or 290 for that matter.
When you make a plan and design a setup to aim for a particular number, the customer and vendor need to understand the goals of the vehicle, the finances, the upsides and downsides, and keep it all in check with reality.
The reality in this instance is that it looks like a 290 is capable of hauling a 1800kg car to an 11 sec pass.
Our 290 project which is DABOSS's auto GT's first time out with our airbox, inlet pipe, underdrive pulleys, difillipo large primary stainless system went 13.19 at heathcote in less than ideal conditions, and backed it up with a 13.17.
It was making 266rwkw at the time, it is now making 277.
Im guessing with a baby converter (customer wants PRIMO driveability retained) and some diff gears, a 12.2 or 3 should be a snack. Then we have
suspension
more exhaust R and D
ignition mods
a few tricks here and there
so there is a lot of scope with an unopened 290. The 260 i think will be at its unopened limit at a mid 12 unless something is done about the weight of the car.
Not forgetting my ute - with the larger converter it went its fastest ever to the half before hurting the auto, so in reality if we put a 4000 converter with a lock up in it, a low 1.7 60 in the GT will be academic. Then we may see 11's.
This is a work in progress ATM, so we will keep you guys informed.
