General consensus on boltons to gain the most HP.

whoady4shoady · 02-02-2011, 12:17 PM

I will be doing all my boltons at once, and i was wondering which ones out there that will give me the most HP without going FI.

So far it seems that the Fast intentions exhaust with test pipes (which TPs do you guys recommend?), and the Stillen G3 intakes is the way to go for the most HP. Would I be correct in my assumption? Thanks in advance guys.

all that and a retune is what I have been seeing as the popular route.

I figured with all the parts and tweaking I would be a quarter of the way to an SC so I am just going to hold out for the SC in April

Yes A tune is a must if you wanna get the max HP out of your bolts on,

I recommend Motrdyne ART Test pipes, they give the most HP over any other Test pipes available for our cars.

I wouldnt mind going that route, but my Z is my DD, and I dont want to have reliability issues. I also dont know where the heck I can get an ECU tune in my area, so Im thinking FI is definitely out of the question.

Anybody know what whp gains to expect fro Stillen G23 intake, high flow cats/TP, and exhaust? I'm assuming they are not additive even with a tune. Maybe 35-40 whp?

cotizi · 02-05-2011, 04:35 PM

20-30 maybe

Jordo! · 02-05-2011, 06:33 PM

Best bang for the buck:

1. TP's or HFC's (ebay test pipes will work fine) ($125 and up)

2. K&N panel filters with HPS (or similar) smooth intake tubes. ($95 + ~$110 = ~$205)

Those two mods (as low as a little over $325) should net you approximately a 6 to 7% increase in power, which on a 275 whp (give or take) vehicle puts you in the 291 - 294 ball park (on a Dynojet).

Based on all of the dyno evidence I have seen, pod filter intake kits are NOT worth it. They are 2-3x the price of the highflow panel filters plus smoother intake tubes and, at best, may net you a few more whp.

That is a great set up. I would recommend an UpRev, and tune just to squeeze out the last remaining hidden horses

I ran Berk HFC's, so I can't comment on TP's.

Yep. Thats the route I'm going. However, they're sold out right now and I'm checking frequently.

cotizi · 02-05-2011, 07:10 PM

that setup is good if your not worried about maximizing hp/$. I ran it, worked great.

Lemers · 02-05-2011, 07:14 PM

Bottom line: there Is no consensus on what's the best bolt-ons for HP gains.

Jordo! · 02-05-2011, 07:24 PM

Actually, to the OP:

I would make a point to get a baseline dyno before doing any bolt on's and them go back, rather than just getting an "after" dyno.

Otherwise, you may be setting yourself up for disppointment no matter what the result is...

pulpz · 02-05-2011, 07:42 PM

So for example,

Stillen G3 Intake +17
Stillen Exhaust +18
Stillen High Flow Cats +16

Total +51 whp

Now I'm guessing all three together don't give +51 whp with a tune. What's reasonable to expect? If the gains aren't strongly additive I don't see the value in doing all three.

370Z JT · 02-05-2011, 10:03 PM

About 30-35hp with a tune. JMO.

Might as well add pulley set and motor dyne manifold to maximize hp b4 getting a tune.

cotizi · 02-05-2011, 10:49 PM

depends on your car. I only gained 5 hp from exhaust, longtube headers, pulley, and tune.
