Just for my curiosity.... do you have also info about your A/F ratio? (maybe a chart) because now I have to do what you did!!!
but because I track the car I'd like to stay .5/.7 on the richer side of A/F... just for added safety.

 

Impressive numbers! How much is the reflash and where can I get it?

 

Great research and willingness to share. Only thing needed now is for you or someone else to map out all the mods,corresponding dynos, cost/source. Then it should be stickied so people dont waste their money on useless items such as pulleys. Again awesome job!

 

Nice gains, especially at 5K RPMs and up.

California speedway would be the best option, but you have to show up really early, only get few runs and it's super hot.

You could do irwindale, but it's only an 1/8 mile. It's open runs every thursday.

 

A.H

can you please provide a breakdown of the cost of getting it to 318HP?

I have a rough idea from reading on here but would like to know a figure if you have one.


thanks,

 

let me take a guess at it man

headers--$$
dual exhaust--$$
injen intakes--$$
pulley--$$
all the dynoes and tuning--$$$$$$$$

having 318+ whp PRICELESS.

 

well... ~800 the headers, 1K the exhaust, 200$ the pulley, 400?$ intakes
plus... 1K for the install and another 1K/1200 for the tuning full tuning?

3500$ to gain 60HP at the wheel is quite... CHEAP!!!!!
to gain 100HP with a supercharger is more than twice on an HR...

 

Well i forgot to have tadashi print that chart for me but i called and asked him about it. He told me that the peak of my a/f ratio was 13.5 and it was almost a straight line.

Thats about right but if you want to get more technical....

Stillen Headers:730 plus 530 install

Exhaust: 1350ish

Test pipes: 300 plus 150 install

INtakes: 539 plus 150 install

Pulley: 220 plus 80 install

Reflash and tune: 700


I know i pay a little over the usual for install but i like good quality shops working on my car and it gives me relief. This is basically what i paid minus the fee for the reflash cause i got that for free caseu i was a beta tester but since i had to pay to retune and do all those dynos i guess it cancells out. Plus you can still get my same power at a lower cost if you buy cheaper exhaust, i know the injen intakes are now on sale, and maybe buying used test pipes. I strongly believe however that my quality exhasut componets by Fast intentions and the inejn intake smade the most of this peak power and the headers smoothed out my powerband. The fact is the NA way on teh HR is not too bad for the amount of power you get for the money. How you get that power and what parts you decide to buy is all up to you. This is just the route i chose and the parts i used were the parts i believed would gain the most power and were off the highest quality. To each to his own

500 for the reflash
150 for inhouse tuning but is only avaliable in socal

Call technosquare and setup an appointment. If you are local just go in and tadashi will take care of it. If you are far just send in your ecu and he'll send it back in 2-3 days.

 

Yea i think california speedway is where i'll be going. Just have to see when i have time. ANd how early do you ahve to be there casue i kinda have to drive a little far and i hate getting up early.

 

how far is it from where you live? maybe we can meet up there.

 

pretty much perfect for power... imho a little on the lean side for "safety" on road course (the air pressure at 120+ mph is going to lean out on top, I'd like to be on 12.3/12.5 over 5500....
you paid almost 4 grand for that kind of power... it's a damn good deal.
you are 30 hp short (at the wheel) of a E92 M3... that is about 3700 pounds

you should really have a trap speed of 110+ and be around 12.5/13 also with a bad launch.... on the road track you should be on par or really close to a 996 gt3 and an R8.... and that is even more impressive!!!!

I'm just waiting for UPREV do release the damn HR osiris... (I'll get the headers too...) and with my setup I hope to go in the 305/310 range.
:skidmark

 

As far as value for money goes its a great deal. you get very nice power and if you decide to sell your car, you don't lose value cause your car was boosted and you will even be able to sell your parts, apart from teh refalsh and get a good deal of it back. This is a huge benefit of being NA and with the HR the power gains are actually worth it.

 

awesome numbers to see man. i hope to be right up behind you. as soon as i get a 3rd and 4th job

 

nice numbers!! you need to get a vid up

 

Making a video isn't a problem and i have had multiple requests, but of what do you want a video of?

wow !~
i like !


so, what is a the final word on injen cai ? is it good for anything ?

Great numbers for a good price. Which mods do you think were the most important to get you to these numbers, and which are prob. not worth the money?

 

The most cruicial mods other than the reflash and tune, which is the most important, I belive the next most important mod is the Injen intake. The headers are also a nice edition but isn't as necessary especially for peak gains. As for pulleys, please save your money as they net no gain. And of course my cat-back and test pipes are also necessary to fully allow the ehaust to fully flow. But basically to answer your question, injens intake over everyone else's design is truly significant even if I don't have an independent dyno.
