Most % power increase with n/a bolts

What is the most % power increase people have made with NA bolt on mods?

Ryguy · 09-06-2013, 08:07 AM

From what i have seen on here, it seems like long tube headers, then probably a cat back exhaust. That should get you over 300 whp no problem.

NA with full bolt-ons seems to peak around 20% whp increase... there are lots of threads with dyno numbers for reference.

nothing you would ever notice except for the weight savings due to your wallet being lighter. but it will sound cooler and annoy the neighbors when you go to work in the morning

Again with the 'you can't feel it' blah blah blah. Clearly you are defining 'feel' by the bottom of your ***.

The hp gains are expensive per hp and some, like Steve over there, don't think they are worth it. If you don't push your car they probably are not by most standards. But if you spend time on closed roads on Sunday mornings or the track you'll appreciate the gains and weight loss.

If you want 'push you back in the seat' gains you need to go supercharger or twin turbo.

You wouldn't notice 30-50 whp? Will you share whatever you're smoking?

Plus the benefits of weight loss...

bolt ons for a NA engine will not give you that much increase, no matter how much ricer math is done or how sensitive your butt-dyno is.

Really? Stock Zs dyno at 270-280 whp. There's plenty of dyno sheets floating around here of 320+ whp Zs.

I can't wait for this thread to be closes...

We argue over the cost effectiveness of NA bolt ons every other day, and all that happens is we waste time by compare còck sizes while none of us use it because we are so busy arguing.

Guys, answer OP's question and let THEM make the decision. Not cost effective for the HP, why do you give a half a fùck? It's not your money, let them decide!

I agree with that.^^^^^^Add 4:08 gears & you can compete with/beat street Camaros & Mustangs. Also you'll be driving an all around great sports car.

If you have no plans to go beyond N/A mods, a car with 4.08 gears and intake/HFCs/catback and tune would be a hell of a lot of fun.

Arrvaxx · 09-06-2013, 10:22 AM

OP, what are the thoughts behind your question? Are you debating the cost/benefit or thinking about skipping NA mods for FI?

Don't forget the performance increase from decreasing rotational mass. The biggest performance gain my car has gotten was dropping 8lbs off each corner with lighter wheels and tires. If I can find some weight listings on aftermarket rotors I think even bigger gains could be had here.

I noticed that much more than the intake/exhaust or sway bar/endlink/springs combos - although I will say replacing the broken end links with SPL ones allowed me to tighten the swaybar (actually re-attach it) and that made a BIG difference in cornering speeds vs running with broken stock ones (and one not attached). Not necessarily a power increase but definitely allowed me to keep the car in the power band through corners much easier.
