I could see that...

That is what I was getting at!

if it was stock headers/cats and you swapped for LTH's maybe.

beat me to it

basically diminishing HP returns the more parts you add. removing the HFCs will be the main reason of gains taking some restriction away.

beat me to it again lol

tp's offer a little more power then hfc. so that might be the only place where he could pull out a few more whp. saying he would get 10-15whp is far fetched. he might get 4-6whp more.

still nonetheless those are nice numbers at 335. seems ecutek is able to provide more power then uprev

yea I mean in freak situations it's possible but likely? not at all.

335whp on a dyno-dynamics seems high to me as well. maybe if it was dyno'd at Z1 lol

Also the dynotronics is known to be low numbers which is why I like it because even tho its low its dam sure accurate if low.

eliminating the cats alone should be about 5, FILTH are a work of merge collecting, equal length art! i would even 2-3... Solid gains man! How does a dynotronics compare to a dynojet

If you do a google search a number of other car forums say between 10-15% lower for a dyno Dynamics as long as no correction factor is used (which is the case here...no correction was used) Most common number i see is that the Dyno Dynamics reads around 12% lower on average. That makes me feel slightly better about the numbers considering the amount of work i have put into the car but...def makes me eager for boost which ill do next feb or so (finances permitting)

if you knew you were going to boost your car, i personally wouldn't have wasted my money getting bolt on parts then.

GZ3 · 07-27-2015, 01:46 PM

im just glad we have another tuning option finally, and it seems to be paying off....i was not impressed by uprev

I appreciate the input but.. Why is it often considered waste? Everything is a build progression. I bought this car brand new in 2009 and didnt know how to drive it to the limit...hell i still dont. First mods were sways and handling components. I spent weekends with the local SCCA and on base at arranged "track" events. Paid the car off and decided i wanted to do more.

So on came a few different types of suspension, headers, pullies and so on. Each time i did the work myself or with friends and learned. (Exceptions are: first clutch and diff. Second time i did it myself and then the roll cage which was a shop in Houston)

After a few years ive managed to push the car and myself, growing both my automotive mechanical skills and my driving skills. Im at a point where i feel comfortable with the car and want to step it up again. Boost is natural and most of the mods i have done will support the Boosted Performance kit.

Personally, and not to take away from those who boosted right away, but for guys and gals like myself for whom this is their first "real car" i think the way i have gone about it should be the norm. I hate to think that id boosted right out the gate and then lost control at MSR Houston or on the road or something just to smash the car and waste my investment.

Each to their own tho and over the years the options here on the forum have changed and grown along with a super supportive group of members who care about their cars and those to the left and right.

because you won't use a lot of the bolt on parts and you won't be able to sell it 50% of what you paid. so it's considered a waste of money to buy those parts when you know for sure you'll boost it.

Still disagree but... your welcome to your opinion.With the BP kit Ill be able to keep exhaust and the headers, Ill have to sell off the CAI and the HFCs. Everything else supports the progression.

GZ3 · 07-27-2015, 05:28 PM

Definitely not a waste man, its all about the journey with modding. Trying different things, better stuff comes out, personal preference in performance levels...every single car ive ever owned ive changed my mind on parts and routes from the original idea when first got the car

Just saw your build thread too. Very nice

The date is off on the sheet but this was done yesterday at Ptuning. There is no wonky calibration factor or any of that stuff.

Staff is exceptionally friendly, tuner was knowledgeable and on the ball and after talking to me for a while about what i wanted to do with the car and the direction i wanted to go offered some options.

Those are some good results.We have pretty much the same mods and are very close in dyno numbers. Good luck with your build.

I'm not disagreeing with anyone but I think some of you are thinking of just bolt on and going. I was saying with the combo of LTH and retune should net about 10whp. And I also said every car is different but honestly if it in all seriousness made 2-4whp why would someone spend 900-1500 for LTH plus install if they can't do it themselves for 4whp. LTH 99.9% outperform shorty any day. I agree with the bolt on might gain 5whp with a retune i don't see why it wouldn't or why it couldn't pick up 10whp over the hfc. On my civic I had i had LTH with Hfc when I switched to a better flowing LTH without cats my car gained 7whp without tuned and another 4whp with a tune. So it possible it's really all in the tune. I do agree that when it comes to NA build its harder to make big whp gains after the basic bolt ons are there but people tend to figure that the flow rate of you intake and exhaust systems plays a huge roll on power the better the flow the better. But I'm glad we have a better tuning software now as well that alone can help make power by itself

Who knows, perhaps it would.... However I'm near the limit of things to do and you hit that wall of diminishing returns. Only way to know would be to buy some lth and test at this point but....not in my build plan sorry.
