I'm not seeing one right now :/

And I know this was done as a project!

one big advantage is it will sound awwwsome

what spec cams are in the car ?
270 profile make peak power under 7k revs so revving any higher is pointless in the quest for more bhp.
I tried this some years back with mine running 270 cams, we raised the limit to 7200 and then 7400 and it made no more power it just flatlined after 7k rpm's. You need 285's to make more power at those dizzy revs.
After living with a kv6 running a slightly raised limit i would never go as far as 7800, when your in 3rd or 4th gear on prolonged flat out acceleration over 7k the engine just doesn't sound happy, and imo it will have a much reduced life expectancy , i know qed ran a 2.0 kv6 at very high revs but a couple of important factors are different on the 2.0 kv6.

Your car ran std injection and std ecu and a restrictive plenum. This car doesnt, so will in no way be the same as your trials with your car.

Once on the rollers we shall see exactly what is what, but going on what we have been told by the people that designed the throttle body system, the breathing will be greatly enhanced.

Sounds good, when do you hope to have it on the rollers?

the plenum, injection or ecu are not the problem here the cams are, but who says the plenum is restrictive at these low power levels, my car and others made much more power than this will through the plenum with nitrous added, and the standard injection is not a problem either, its been proven to go over 250 bhp.
Thats all irrelevant however as the cams just cant do it, see this copy and pasted from motorsportworld website, specs from piper for the 270 kv6 cams says specifically that the powerband is from 1500 to 6500 rpm's.

" Kit comes with cam, followers, timing disc and cam lube.
Powerband : 1500-6500rpm ; Power increase : 20bhp
Inlet duration : 260 deg ; Exhaust duration : 260 deg
Inlet valve lift : .380"/9.65mm ; Exhaust valve lift : .380"/9.65mm
(Valve lifts quoted assume a rocker ratio of 1:1. )
Timing (Inlet open - close) / (Exhaust open - close) : 20-60/64-16
Inlet full lift (ATDC) : 110 deg ; Exhaust full lift (BTDC) : 114 deg
Valve clearances : N/A"

Well we shall see wont we !

Nothing is ever written in stone ! oh and forced induction works in a different world to normal induction, which is why having cams designed for nasp didnt work on a charged engine.

good luck with itll be good whatever the outcome

Can it? Has anyone actually done this?

All supercharged cars have an additional injector to increase the fuel needed for the additional air .

I do know that the std injectors are only good for 38bhp each on the std fuel pressure, which would mean that they would be maxxed out at 228bhp!

We are not running the std injectors and our new injectors flow 57bhp each at 3 bar fuel pressure.
