Supercharged mustang engine issue

[Cat B Repaired]

Hi guys

A friend of mine has recently imported a 2006 Mustang 4.6 Supercharged V8. This was supposedly pushing 450/500 Bhp before being imported into the UK. After delivery we test drove the car and felt it was running a lot less power. He has owned two mustangs in the past so is pretty sure about the power loss. Could anyone point me in the direction of a mustang specialist within the Midlands area?

The claimed power from the US is usually quite far away from reality as they use Dynojet - hence all these great numbers on US forums. As a rule of thumb a rwhp dynojet reading would equal crank reading for a dyno dynamics so I wouldn´t count on 500 hp. Just to have an idea my car read 440 rwhp on dyno dynamics and 510 rwhp on a dynojet (Sallen Stage IV, 3.2 pulley, long tube headers, stage 3 cams and spot on tune, and this is more or less the max you will squeeze out of the stock bottom end)

you can have many reasons for power loss - so far I lost power once when the chargecooler pump was gone and once when one of the spark plugs was gone.

I would also call Mike at modurstang or Trevor at Surrey Mustang to see what they have to say. Btw. what gas is the US tune for? If you need a new SCT tune definitely get one from JDM - really great email tunes and they got mine spot on from the first time when I upped the boost and installed the long tube headers.

Cheers for the help guys

Not really sure about the current tune but I do know we're looking for a new tune after the cars been through a full health check. Would Mike or Trevor be able to give the car a once over for him? if not could you guys recommend a good place for a full check up?

Both of them can do a full check up, also both can hook it up on the SCT to read error codes etc if any. Furthermore ask them if they can hook up the Ford Livelink - then you can drive around and monitor quite a few parameters on the laptop to see if everything is ok (timing, separate injector loads, sparks and many more).
If everything seems to be healthy then you go for a dyno session to see the AFR and what hp are you pushing and think of options to get more (you know some is good, more is better but on a stock bottom end the limit is about 450-475 at the wheels on dyno dynamics, after that the rods won´t cope with it)

out of curiosity, what sc do you have? saleen, edelbrock, whipple, kb, paxton?

for tune, JDM are really good, quite a few people on the mustang forum went with them

Mike will give it a full health check and will be nearer. Never seen a bad review of his work.

Cheers guys. Will definitely be giving a mike a call for an sct check and livelink. I don't know much about the car unfortunately as i am posting on behalf of my friend but I do know that it is a "Steeda" if that means anything lol!

Steeda is a well-known and respected Mustang tuner in the US though they tend to use proprietary parts from other manufacturers as well as their own bits and pieces so it will be a proprietary blower. They make their own "Screaming Q" models.

Hi Cat B,
I am Mike from Modurstang.
A guy called me up a few days ago about supercharger issues on a rescently imported Mustang, though that was a Vortec,
You said Steeda.. Are you sure you dont mean Saleen. If so then give me a bell and we can sort it out.
Thanks. Mike.

Hiya Mike.
My friend did give you a call earlier on in the week with the issue with his vortec supercharger. The front bumper has steeda written on it which is all I knew about the car. Sorry for any confusion
