so I have been thinking about getting a NB with a 2.5. and I have 2 questions.
I have noted that the rabbits hp went from 150hp to 170hp in sock form, but the NB did not get this gain. anyone know what VW did to get this gain in the rabbit, and why the NB did not get it?
also I will want to chip the car and I have been looking at GIAC cus most people have said there chip is the best. but on there page the stock power was in the 140's I would guess this was the 150hp motor and that that was true wheel hp so with drive train loss and all, chiped it was much better 10hpish, but that doesnt seem to match the 20hp VW added, also does GIAC have a chip for the 170 motor I could not find it on there page,

in crank hp.
150hp-160ish hp = giac
150hp-170hp = VW
170hp-? giac
thanks all.

Re: 150hp-170hp and chiping. (elmer fud)

There has been a lot of debate over this. The difference is in the computer, intake manifold and valve train.
I think VW lied about the 150 hp engine, because a lot of those dynos show that it has more then 150 hp, and these are Rabbits and Jettas.
Now I don't know about the NB motor. There is an air box difference between the Rabbit/Jetta and the NB.
Also, I'm not sure about chipping on the NB.

vw "made" or said that he 06 is at 150hp and the 07+ is at 170hp the only difference between the two is th diamater of the airbox and certain lag codes in the ecu ive ha dmy car dynoed a dew time after mods and the horse power never read as it did from vw the first time i had it dynoed was bone stock and at the wheels it was 160 after the exhaust and intake it was 165 and now that i am flashed it was dynoed at 180. the guy who flashed my car buil it from the ground up usuing an 08 ecu and removing a number of lag sensors and tweaking the rpm limiter so now instead redline being 5800 my red line is 6800
so far so good with my rabbit...as project c2 turbo stage 2 begins

Re: 150hp-170hp and chiping. (slownlow2.5)

okay, here's the newbie dumbass question of the day. I thought it was the 08 that came out with the 170 whp. some say it's just an ecu change that took the 07 from 150 to 170 for the 08. that's where the GIAC chip comes in for the 07. in any case, has anyone done the C2 turbo for the tiptronic tranny? i really want to do this but would like to hear from someone who has already done it, and what they think of it.

bump.

Thanks for posting up a shot of my engine bay....But the cover is painted too now...


I have been holding off on chipping because you just don't get much for the money... 10hp seems weak for 300+ bucks.

lol you cant justify spending $300 for 10hp and 14lbs/tq but you can for spending $300 for that intake that got you 5-7hp and 10lbs/tq?

And a sound so nice I have not payed 700+ for an exhaust!

Borlas sound amazing on the 2.5, they don't drone at all on highway and get loud when you romp on it. http://****************.com/smile/emthup.gif I am looking into the C2 chip for the 2.5 http://****************.com/smile/emthup.gif A local group buy for even cheaper prices FTW!

just a update bump.....
I work for vw, and I am the original poster, after no luck here I started asking inside the comp. I found out from a very reputable source, that the beetles also, got the 170 upgrade also, he has no idea why the advertising department felt no need to tell people. lol

Re: (Xyphyr)

borlas dont have highway drone? ha only if that was true! my single borla gets real annoying at 70mph thats why i cruise at 72. and yes they sound amazing, especially after a 2 hour drive home and getting on it. but i do have to admit straight pipe sounds even better, would do it but would loose too much back pressure. heard it when was putting new exhaust on after the cat and did it sound even better then a vr. all they did from factory to get the extra 20hp at the crank was a little bit more tuning. and you might as well not try to go to your vw dealer for the updated flash because they wont do it for you, trust me already asked and got story of some big dealership in chicago and almost loosing there franchise. p.s. i have revo flash

I'm still undecided on ever chipping the Rabbit. APR has stated on here that they haven't produced a program for the 2.5 because it's not worth it (as in there's nothing to gain), especially for the latest 170hp engine.

Re: (seanmcd72)

the reason they say that because its an n/a motor. so really they cant make big power by adjusting fuel trim, timing, and boost. so they prob wont do anything because they cant in excess of 50hp.

who cares what APR thinks? look at the price, look at the gains, and you decide for yourself if its worth it.
oh and btw, the same gains that were seen on the 150hp motor are the same as on the 170hp motor
