Streetfighter 2.3 Supercharger Package

[Streetfighter Mustang]

I was looking on your website, about that warranty and i have to ask a quick question.

The Ford Racing Supercharger kit comes in at 670hp... i do recall last year the Ford kit was lower than the Roush kit, but now they are both the same and both kits use 47 lb Roush Injectors..

(i know they are the same kit, but the tune's orginally were different)

You still have the ford racing supercharger kit at 630hp on your website... does this need updating?

Also, im a little confused. the supercharger Kit with the SF full header back exhaust was 680hp

So only +10hp more than the 670 kit.....

I did notice both kits now use 47 lb Roush Injectors.. was that not the case when you did the dyno.

Cheers,

We cannot compare with the U.S figures.
U.S flywheel horsepower is most often quoted with no ancillaries attached eg
alternator , water pumps ete etc.
This makes for a higher initial reading.

Our Australian SF Mustang figures are quoted from actual rear wheel power on a chassis dyno and then generated to estimated Flywheel horsepower.
This equates to the 630hp at flywheel we are seeing on AUS mustang with the 2.3 Superchargers.
Add an exhaust with long tube headers and we are able to make more power with same boost. approx 670-680 fwhp.

47Lb/480cc injectors will only support an absolute max of 630hp at flywheel. This is why we upgrade to KPM1000cc injectors beyond this level.

Thanks for that, its a good starting point.


So how is the US fuel better than ours in Australia.

98 Ron is the same as 93 (USA) and we get E85 here as well, well in QLD that i know of.

This helps out a lot, why do those companies talk up there fiqures, if it doesn't include ancillaries.... no one runs without those in the real world.

I suppose HP sells

It's good to see someone be honest.

So just to be clear. that with the SF header back full exhaust hp increase to 670hp, that requires the larger injectors...

 

[Streetfighter Mustang]

Yes, larger injectors are needed with anything higher than the 630hp kit.

Not bad I think guys. How much is the drive line warranty David?

Drive line warranty is included in this package.

Hmmm this isa pretty good, in the budget too!

Hi David, How much power does this 630hp kit make at the wheels? Can you post a dyno sheet with the wheel power?
