$3,000 = 50hp

[jetguy]

import tuner mag jan 11 has a dyno review of all the breathing mods and it turns out for around $3000 you get an extra 50 horse power.

so.....is it woth it? 50 little hp for $3000 large?

[RedBullRR]

Doesnt sound like a fair deal

[Jamaica]

double that and you have a supercharger numbers(kinda). or triple it and you have a tt kit with guarnteed power

[tjlazer]

For FI, you still need an exhaust which is about half of that quoted $3000 price....

You've got to pay to play!

The Z only sells around 10,000 units per year. There's not enough volume to keep aftermarket costs low.

[jetguy]

There is no need to upgrade exhaust for a supercharger system, infact most companies will quote improvments to power with stock pipes and their supercharger system.

[m4a1mustang]

That's true. But when factoring in the cost of FI make sure you include all of the supporting mods... clutch upgrade, gauges, etc.

[jetguy]

But I would add some hfc's

First of all, it's not a gauranteed gain of 50 whp, because those numbers are all based on power added to whatever you measured as your starting point, and all of that will vary from dyno to dyno (and also vary by what correction factor is used) -- it's really a gain of x%.

Going with dynojet #'s, I'd say the average Z puts down about 275 whp (AT and MT) and maxes out around 300+ to 305+ whp. That's a gain of about 10% to 12%.

That is a substantial bump in power and torque, but no it isn't going make your car as fast as something like FI will (a typical gain being around 25% to 30% or more in power!).

As to costs, you can always buy stuff used or scour ebay to save money.

I've bumped my car up by about 10% from baseline and have spent under a grand.

Best bang for the buck mods: K&N panel filters (seriously) and either test pipes (cheaper) or high flow cats (more costly).

No, that is 50 hp total gain with hfc, cbe, gen3 intake, and uprev tune. Total combined, not tuner math of 18+30+18+20. They added after each upgrade. The gen3 which is good for 18, onlyh added like 3hp to the numbers after the exhuast for example.
Btw, do you have any hard numbers you can share about the k&n filters?

[ClemsonWill]

I don't think you can solely look at the hp gains. Bolt ons change the sound, throttle response, etc. Not to mention the reliability aspect of going FI.

If you are solely looking for the best bang for the buck you should just hook up a nitrous system.

[efuseakay]

And the tune. Some tuners are more capable/knowledgable than others. Using finite numbers to tell readers that every Z will get those exact results is quite dishonest IMO.

[Jamaica]

kinda simple thou, if you want real power FI is the way to go unless you want to add a 4.5 liter

You're missing my point... I am talking about total gains for ALL bolt-ons' combined, not ricer math piecemeal gains -- my point is that the meaured gain in real numbers (i.e., 50 whp vs 30 whp) will vary from dyno to dyno, and somewhat from vehicle to vehicle, but the proprotionate overall gains should be similar.

Never mind...

I have numerous dynos posted and I have gathered data from other folks nice enough to share their data (actual dynojet runfiles) tho I don't post it without their permission.

Regarding the K&N's in particular, there are several dynos posted both by me and others.

If you're gonna engine swap why stay in the Nissan family of engines? I say shoehorn the biggest / most powerful engine availible into the Z.
