there you go

ps. i herd his number was 1-800-SPANKME

 

You need to read a little more before posting. I agree AP+suspension make the most noticable difference. Ask me how I know.

 

HPDE events.
Autocross events.

AccessPort from Mazda Manaic.

 

why would I need to read more? I don't understand. Cobb's free pdf document for their rx8 AP indicates that, after they tuned on the dyno, they found about a 5.5% increase in BHP. So, 185 x .055 = 10 bhp gain. And as for the midpipe, well, according to the various sources and opinions on this, it seems that exhaust mods for the rx8 pretty much just change the sound, but don't really add anything in terms of actual power/torque increases. So, this is how I base my conclusions.

So, Cobb's own literature on the subject plus the general consensus on exhaust mods apparently is completely inaccurate?

Again...what is it that I need to be reading?

 

You can start by reading the results of my dyno tuning session with Mazdamaniac posted on this forum to know that I picked an average of 9hp across the entire rev band and peak of 15hp. Getting the AP by itself is the first step. You use it to get a custom dyno tune for your car. If you'd read up on the AP you'd know that as well.

As far as exhaust mods. I didn't recommend that but there you are partly right. The cat backs get you 2 or 3 but swapping out the cat. can get you ~5-10.

Shocks and sways can do a nice job of firming up the ride a bit and increasing your cornering power. The ride is great out of the box but you can take it from ~0.89gs to the ~0.95g range as well as increase your slalom speeds.

The Grand-Am ST class cars that run the renesis use a stock airbox, custom exhaust and tune their PCM. They get ~220hp at the wheel NA. TeamRX8 with a tune and custom exhaust was able to get ~220whp. That's about a 30 hp increase.

Like I said. Read up before you post. There's a lot of junk out there but there are some good mods if you do some research and read the results of other people's work.

 

Thank you Shaun

Genesis's post made me

 

who is Genesis?

And again, why would my post about 5-10 bhp make you frustrated? Cobb states 10 bhp increase with their professional tunning....and exhaust mods from what I can tell don't add anything considerable over the rev range, besides maybe a 2 bhp blip somewhere. Also, Shaun basically agreed with me when he said he got a 9 bhp increase across the rev range, plus a 15 bhp peak somewhere. for the most part, getting a 9 bhp increase across the rev range seems to fit with my claim that Cobb states a 10 bhp increase in their literature.

I am very confused.

 

^^ likewise. rg - "exhaust" is a loose term here. catback alone, you're right, won't do MUCH, but even 2-3-4 hp when we're talking about <30 is something, you can't just say it's nothing. and further, a midpipe was mentioned...THAT is the key to releasing more hp when talking about the entire "exhaust system", not just the catback.

i think the confusion is someone said 15-20 hps, and you said MAYBE 5-10. well, now we're saying a solid 10 w/ the cobb alone, plus the midpipe and exhaust, so we're already up to 15-20...not the 5-10 that you said. that's all...

anyway, i gotta save up for the cobb

 

you are.

first. the stock cobb stage 1 map noticeably improves the power all across the band. regardless of top end power, i will out accelerate you, because my power band from here to 9.5k is fatter.

and... a catless 3" race pipe IS 10whp.

no discussion.

just accept it.

ok?

 

get a LS3 engine, you get 430 hp on pump gas.

 

thats right put an LS series in a mazda

Reposted in case it was missed



Ok...

1st. Midpipe and Exhaust ARE NOT THE SAME

Exhaust will give you 2 maybe 3 at the most

Midpipe will free you from the cat and you can widen out the piping - true you may not be able to open to a FULL 3" midpipe unless you replace the headers out but that doesn't hurt it's cause.

I think you may be confused on which mods actually produce a 'gain' and ones that are aesthetic.


2nd. MM's tune further manipulates the Cobb ap maps by actually tuning TO THE USER'S CAR. Because we all run differently (too rich, too lean) the results will always vary - to range between 5-10 would only reflect a fraction of the results that have been posted SEVERAL TIMES ON HERE.


It frustrates me because it amazes me how many people contribute to this forum with hard facts and data and yet people still manage to be oblivious to it. Have you researched the dyno threads? Comparisons dynos? the AP Discussion thread? If so, then it amazes me even further how you can say that a midpipe won't make a considerable difference? Ever seen a turbo with a cat on?? No? Ever wonder why? Midpipes make a difference.

Shaun said 9hp...true. But he explains that he peaks at 15 so technically it's outside of your range, rendering your statement false - that's like me saying "That turbo will give you 10 whp....oh, you dyno'd over 300whp?? See I WAS RIGHT! YOU MADE 10WHP!" You get no brownie points for guessing the obvious.

and your name is Genesis for two reasons. 1. I already refer to another member as Renesis and i would hate to get you two confused. And 2. I don't know your real name(nor do i need to know) and i don't care to type out your entire user name.

 

Your posts make me sad.
Give us these "reviews" of the 8 that show a slower upgraded suspension vs. stock by the same driver in the same conditions.

 

^The V12 is more impressive lol

 

lol....... i bought a toyota mr2 for $200 as a daily driver

 

I agree with this suggestion

 

lol havent seen the v12 one

 

I recommeng getting a decent set of tires. Nothing beats grippy tires

 

sorry for late reply.
i had to work all day yesterday and today.
just got off work.
I am focusing on little bit of look and power.
thinking of getting high flow cat from RB or wait till BHR comes out with his midpipe.
but don't really want to smell gas in my car plus it's gonna be loud with the ap exhaust that i want.
probably i will get cobb AP from MM/ap exhaust/clear corner/changed some lights to led/short shifter/shift know/lowering spring/appearance package
and when i save some more money then i will get ings+ body kit + new rims/
what do you guys think?

 

s techs- 200
AFE SHIFTER- 300
Progress sways- 300
remove your vfad- free
eyelids- 60
led interior conversion 40
400-savings for rims and tires

 

Uh huh. So is 10hp peak the same as 10hp average? Is that the same as Cobb advertises? Is that a waste? How did I agree with you again? So I'm guessing you haven't checked out my post yet because of your "somewhere" comment. where should the peak gain be with a proper tune? My point still stands that spending your money on a Cobb AP tuned by MM and suspension upgrades is the most noticeable gain in performance you can buy for $1300.00

 

Lol , like i said just buy a full header back exhaust and an accessport. But thats just me , i like sound from a car >_>. Also imo stock suspension is good enough for the street , honestly we cant answer anything because we dont know your goals for the car... But thats what i would get for first mods .

 

huh? ha ha, ever heard of the 'enter' key??

 

If it was me (and I like power )

Aem intake: 300
Cobb:600
midpipe:300
Clear Corners: 100$ (or less)


There
Or
For suspension:

Front and Rear Sway Bars
Tein S-techs
Strut Bars
Hawk Pads
and.... Crap I don't know **** for suspensions....

 

if you tune the driver, suspension mods are not needed as this car stock outhandles 95% of everything out there
