Couldn't agree less.
My mate ran 9.95@136-138mph (VL) with 1.6/7 60'ft marks making 367rwkw
On 9 or 10inch slicks with front runners.
So if someone were to run with 450rwkw and full slicks, you'd expect nothing
under 140mph to justify the claimed power output.
Hell...with that much power you would expect a 10sec pass on re-treads...
However, if the stated power is correct on such little boost pressure...that person would probably put GARRETT out of business if he could supply Gt3540's that may produce that much power on such little boost.
GARRET would probably discontinue production of the GT45's
