Costs per HP gain unworthy for our Z's

TongMan · 07-26-2010, 02:32 PM

I highly doubt that as the Mustang GT pushes 412 hp stock for 30k.

Intake: Stillen, Injen, or AEM Cold Air Intake
Exhuast: Stillen, F.I., HKS
Headers: HR Longtubes
Tune: UpRev Tune, Cobb AP

So, I've calculated the costs of each part and compared it with the amount of hp increase.

~$500 for a tune for ~10 hp and 8tq
~$1700 - $2500 for catback for ~10-20 hp
~$1300 for headers for ~10-20 hp
~$500 - $800 for an intake for ~5hp-10 hp

When you think about the cost vs the hp gain, it just doesn't seem worth it. Or am I the only one that feels this way?

Buy a GT500 then. Seriously. Or do what I did, get a group buy price for a catback (My Berk was under $1000) and find a used CAI (My Gen3 intakes cost me $300 used).

Don't want Mustang. Buying used is probably the way to go. Thanks.

I had a Audi TT and a canned tune for it gave me 50 hp and 80 tq on a 2.0t 4 cyl. Add the downpipe and CBE and add another 20 or so hp/tq. I had over 300 tq on a fwd car.

Well I came from owning a 05 STi. Bolt ons for that car got you crazy power for dirt cheap but the stock turbo maxed out really fast. After the basics, you had to go with a bigger turbo for any substantial gains. Don't think upgrading the turbo on that car was cheap either. I priced out a modest build (~450-475 awhp) and it was going to cost around 10K.

I can put 6-7K into a supercharger for the Z and be right about there. So really it depends on your ultimate goal. If you want a nice jump in power for cheap, the Z isn't going to cut it. If you want 450-500 whp, then it's actually a decent platform to start with.

Mustang GT500 is $48K base with 550 HP and 510 ft-lb's torque. Also dropped over 100 lbs from the 2010 model, mostly from going all alluminum engine.

I mean for the price of all those parts you listed you basicly hit the amount needed for Stillen's SC.

MMC Racing · 07-27-2010, 01:58 PM

This is nothing new. We had the same "problem" with the 350z platform. If you want significant gains you have to go F/I.

Often true on most import platforms.

The s2000 often loses HP with breather mods....

True... the Z does have a modest increase in power per performance, but the Z can be made lighter in weight. Those modest gains then become more significant.

And besides that, the Z is a freakin looker. I love the GT500 and the new Stang, but the Z has that WHOA factor.
