Year?
Mileage?

Not saying I don't believe you, but I'd love to see the graphs proving this.

 

 

I don't care whether you believe it or not. It was tuned at dynosty on a dynojet. It's an '03 touring. It went from 219 to 249. That is not a high number. I posted the final dyno chart a while back. I didn't get a copy of the baseline dyno, hell it was rough enough posting the 249hp dyno.

 

219 to 249 is somewhat believable; I'm betting the tune had the biggest impact.

I thought you were going to say you went from 260 to 290...

 

i know the first time i had mine dyno'd, i was disappointed to say the least

 

Sadly, no. I agree that the tune more than likely had a big part to play. But if you're going to do those upgrades, a tune is needed anyway.

 

I dont think any of those will really make a difference in the way the car feels. If I were you, i'd go with exhaust mods. You can at least make it sound a lot better with a catback. Add a tune since that makes the most power anyways. Leave the intake side alone for now. Just my opinion.

 

I chose to mod the intake and exhaust for sound purposes. I knew I wouldn't be gaining a lot of hp, but I wanted it to sound better. I love the sound of the borla exhaust so that's why I went the way I did with my mods. Roughly $2500 to make it sound better. Though it did perform better after getting it tuned.

 

Ive got a sweet borla exhaust and berks high flow cats and a dc intake along with some other things... I know they have not given me any gains because they are sitting in my basement collecting dust...

Come on spring.

 

wont matter if the bolt is still stuck....

 

I really enjoyed doing simple bolt on stuff. I doubt I had any gains from the stuff I did, but it was fun. I still have most of those mods so they help now. I did an AEM intake, strup headers, intake spacer, and catback. The only thing I sold when I went FI was the intake. Everything else is on the car. The catback made the biggest difference to me, just because of the sound. To be honest, it was a bit loud, but I did like the improvement.

 

Whatever they did, it fixed the issue of the front two ports not getting enough air.

30hp isnt alot of HP. And it might not even be worth forking out the cash for it. What I dont understand is why some people are in complete denial of bolts on's + tune having any significant power increase. ~$1200 for 30HP or even 20 is not so insane.

Curious as to why you think he would say 260 to 290

 

On a VQ, yes it is insane (especially the DE).

This car is 13 years old. Multiple people have tuned full bolt-on, top of the line parts, and few have seen increases like that. Even fewer break 300.

Because a lot of noobs claim it without actually getting their car on a dyno. They assume they are at 267 stock, then use the claimed HP increase printed on the box of their ebay parts.

"The box of my K&N intake says 30HP! I started at 267, so now I'm at 297!" No.

I've seen this bullsh*t too many times, so now I actually question gains to try and mitigate the misinformation these schmucks are perpetuating.

 

^^^ This.

& if you install HFC's.. You will not pass smog in CA. Our smog laws are the worst in the nation so much in fact that we have more restrictive & expensive cats than every other state. Exhausts you can get away with, even high dB.

But honestly if you really want to get the best bang for your buck..

Suspension first.

 

When I put my Borla, Test pipes, and Injen Intake, I lost a TON of power down low for maybe a slight increase in top end (2006 revup) I think the dream of power is alluring, you are better off selling your DE and just getting an HR for the price of some of these mods.

Just got a 2008 nismo with 14k miles. I remember when I tried defending DEs. HRs are just that much better. This time around I might get intakes and Exhaust (mostly just for sound) but i'm going to wait on cats until I can afford LTHs and a tune at the same. time.

 

maybe when I get home I can look for my dyno runs but I cant honestly say which mod in particular did the best for me, I would assume the tune, but its probably a combination of all of these. If I remember correctly at the wheels pre-tune but after mods was 246hp and 226tq after tune I was at 278hp and 256tq.

not really sure what it would have been completely stock with tune, sorry, but here is my mod list when I got the tune.

-kinetix test pipes - fortunately we don't have to try and pass any type of emissions or roadworthy whatevers in Tennessee
-JWT lightweight flywheel and clutch
-invidia q300 I think or something like that catback
-motordyne 5/16 copper plenum spacer
-popcharger

the best thing I would say, no matter what mods you do, you wont get the true benefit from it til you get the tune.
