Okay so in a month or so I'm going to finally do some performance mods to the car. I have my car registered in columbus, ga but i live in atlanta, ga so I don't have to pass emissions because there is no emissions testing in columbus...so I'm definitely getting the test pipes put on my car.

List of performance mods:
1. Stillen CAI
2. Stillen Cat Back Exhaust
3. Stillen test pipes

With the assumption that each modification will give roughly the same amount of horsepower, about 10rwhp a piece. So I can assume the G35 will have anywhere from 330-350bhp. Do you think these mods will give me the edge to hang with 335i's? If yes, what do you think this car will run in the 1/4 mile?

Thanks guys

 

Personally speaking i have a stillen intake and exhaust and my dyno numbers went up like 1-5hp. The claim of getting 10 for each mod is a fantasy. IMO if your racing a 335 your most likely gonna lose. If the driver of the 335 doesnt know how to use manual (assuming thats what he has) then you have a chance. The torque is what makes the difference.

At the end of the day they have twin turbos and we do not.....but just imagine if you did then you would be smoking 335 all day everyday.

BTW if the owner of the 335 has ecu upgrades dont even bother using your gas!!

 

1/4 mile stock were running 13.9-14.3

There is a youtube clip of a guy running his stock AT G35s at 13.6

With the stillen mods youll be lucky to be running 13.7,13.8,13.9

all depends on temperature,elevation etc etc

 

even though i don't like it, you can always add nos...

 

A Buddy of mine just ran this past weekend in his Bone Stock G35S 5AT

13.80 @ 101mph

I would hope he'd run better than a 13.7, 13.8, 13.9 with those FINE STILLEN PRODUCTS.....lol

 

have you been to the track yet ultimate?

 

unfortunately no i have not...both times i got time to actually make the drive it rained out or some accident happened and they closed the track

i really wanna go run n see what the G has.

I would be really disappointed if im not in the 13's

 

damm nice run

yea like i said the elements play a big role.....the Stillen products are fairly well built (dont know if that was sarcasm in your remark) the exhaust def has good craftsmanship and design. The intake..ehh what can you say its a rubber tube with a huge k&n filter on it.

 

Exactly!! The upside and downside of the internet..... TOO MUCH information. When everyone first starts modding a car, they go to websites, add up the "Claimed" HP gains then think that's what they'll make.

With those 3 mods, you'll be lucky to gain 12-15hp total. That's at the crank!

On my last car (2002 Trans Am), if you believed all the internet claims for bolt ons, you could easily have a 500hp car just doing all the bolt-ons (no cam, heads or internal work). Unfortunately, that isn't the case.

For the most part, cut the claims in 1/2 for realistic gains. Then, when adding them together, only count 3/4 of the total.

Example.

Internet Claim: mod 1: 10hp, 2: 10hp, 3: 10hp.

Reality, 1: 5hp, 2: 5hp, 3: 5hp.

1 and 2 together: 8hp

1, 2, and 3 together: 12hp

That's pretty much the reality for bolt ons. Internal work and forced induction is a different story. But, for bolt-ons, there only so much power you can gain by making the car "breathe" easier.

FWIW, the stock intake and exhaust already flow decently. Do those mods more for SOUND than power. You'll be lucky to gain .2 seconds in the 1/4 mile.

 

The elements do play a major role, BTW those runs was at the Nopi Event this past weekend at Moroso. He ran 13.8s all day, not bad at all for bone stock. Even left the G35 Coupe he ran on one his passes asking, "What you got in that thing?" And he wouldnt accept the fact it was Bone Stock b/c he got whooped on....

There was a lil Sarcasm in the remark but not to knock that their products are crap. lol Just that their products aren't always "BANG for your BUCK" (like the intake you brought up) and they dont really give you all that power that they claim to bring. Do I hear a G35 track night at Moroso?

Back to the subject at hand though, Those 335is Trap anywhere between 103-106 and run in the Mid 13s in the 1/4 mile STOCK. Those Mods MIGHT get you close to a Stock 335i but mods like a catback and a reflash (ECU) gets them into the 12s with trap speeds up to 110mph+. I think you know where this is going but do get some comparison runs (Stock vs After Mods) to see what the mods really do for you.

Hey bro i live in Davie/Ftlauderdale so whenever your down to do a lil heads up 1/4 mile let me know!!!

i reallly need to see what my car runs its killing me!!

 

Man, I really don't feel like doing any performance mods now haha

 

I can understand how companies would want to hype their product up, but do you think stillen really uses fake numbers to trick their customers? I think it would be difficult to dyno an intake because the car isn't moving and unless you have a giant fan in front of the car, the extra wind coming under the car would be non-existent. I guess it's really nitrous or FI then...and neither sounds good to me since NOS can blow stuff up and FI would mean that I should have 15,000 in disposable income in the bank account. anyways, thanks for the replies

 

why would you say that? Did you know that with an EVC, you can control how much your turbo is boostin? (i hate superchargers) so this way, you can easily boost 5-6 lbs daily... which you will definitely feel.. shoot even 4 lbs will give you great noticeable power... When you want to give it a go, you can push a button and boost 8-10lbs... WOW turbo is amazing..... and this is why we'll get smoked by the 335 cuz a lil chip can bump up the boost...

I really think any bolton's are a total waste of money when compared to the hp gain you get from it.. but that is my opionion.

But for me, 306hp is good enough...

 

dont assume with ricer math. i would also look at better quality brands with test pipes such as berk, FI, etc. have not heard of anyone getting the stillen ones.

with those 3 mods AND a tune you will be lucky to gain close 20whp...
