I have the Track Struts but with Eibach Sportline springs which are stiffer and lower. I find it fine for daily driving.

My mate has the Streetfighter exhaust with headers. I think it is the right volume for the street, and is not too raspy.

Interesting mod list, have you put yours on a dyno after the lund tune?

It has 300kw at the wheels at the moment (Harrop Supercharger coming). The biggest gain was the Streetfighter headers and 200cell cats, due to the restricted manifolds on RHD cars. If you do Lund and Headers/cats you should see the same.

Would love to see the dyno sheet on that one, they are some great numbers. I haven't seen an Aus car pushing 300kw yet with full exhaust, tune and cai

I don't have mine on me, but have a read of these threads. They explain what is going on with the RHD cars. Detuned and restricted. The Streetfighter car in the first thread pulls over 300kw as well.

hmm where is the 300kw at the wheels posted? I cant see how this is possible without running a dangerous tune.

Keen for some info!

ah ok. Didnt read the whole thing. Not sure i believe 300kw atw given they are estimating based on Chassis dyno.

Would love to see real confirmed figures from a car that has this fitted.

Anyone??

or is this on a US car?

Chassis dyno measures atw. It is not an estimate. The graph below is a Flywheel estimate (which is a long way out in my view as it is using 24% loss which is way high for a modern manual).

Their test car is a US car with Custom tune, full exhaust and CAI, but that makes no difference.

hi aus-mustang . CTB performance specialists in auckland claim 400 KW on the dyno after a tune, CAI and full street fighter exhaust. i believe that equates to about 300 KW at the wheel? tom

They dyno'd 300kw at the wheels which is about 354kw at the flywheel. For some reason their dyno is correcting it using a 24% driveline loss, which is way too much for a manual rear wheel drive car.

Anyway, plenty of US cars are making about 420hp at the wheels with the same mods, which is a little over 313kw, so my 301kw seems a little down on power. :cool:
