Just wondering has anyone put into consideration lifting the current X275 class single turbo from 80mm to 88mm?
In the rules section it says you can run 2 X 62mm which has approx 1450hp pontential or a single 80mm which has about 1230hp potential.
Lifting the single up to 88mm which would level the playing field to 1450hp potential and line up with the X275 class in the US.
Having an index of 8.5 is a great idea for x275 class but unfortunately for people like me who want to join in on the action with a late model commodore or falcon that is still street rego’d, An 80mm turbo just ain’t going to cut it. To heavy of a vehicle, but that is our choice.
Would be close to 4200lb with driver and cage. With good traction might go 8.75@150ish with an 80mm turbo, It would all depend if I could get it to hook. There is a lot of weight to transition in an irs car unfortunately. If it was up’d to 88mm, Could keep the boost low of the line then use the bigger wheel to bring it home. Nether the less 80mm it is.
Blokes have been 155mph on a 4450lb Chev a truck (brick) with a single 80mm a borg Warner on a mild 383 23 degree Chev.
Anything running sub 9’s will be competitive on the day without a doubt. I have no doubt a mid 9 sec car if consistent could snag a win.
