Most % power increase with n/a bolts
 

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

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!

Ok, I'll re-do my post in percent to satisfy the OP's question. :p

Somewhere between a 10%-20% gain.

Lol!!!

I wasn't complaining to or about you!!!

exactly. my original comment was about my experiences and use of bolt ons in the past and was poking a bit of fun, OP hopefully can make up their own mind and do their own research on stuff rather than going the route of so many others that just go by manufacturer dynos and toss on a bunch of stuff, only to be disappointed they did nto get what they paid for. sure it is easy to tell someone to go spend money, it's is not your money. maybe i am just the person that don't like to see newcomers to cars like ours get screwed over by these parts manufacturers and their bloated HP gain numbers

I know. I'm just bored at work and hoping homie here comes up with some kind of explanation on how all of the dyno sheets we've seen here are wrong, and bolt ons don't make power.

Users here have posted their dyno sheets. Not manufacturers. I'm confused where the question is.

40-50WHP for a couple grand is A-OK by me, that's really not a bad return, yes you can go nitty gritty with the NA mods and that's where cost/HP goes down, but it's part of the fun too IMO
