Last week I dynoed the z after installing the GReddy TT, and got 313.
Back this week to the same Dyno after installing test pipes w/resonators and got 350

So alittle more then 35+ HP Gain!
I knew those dam cats were holding it back

Now time to up the boost!

312-314

37 HP is a heck of a gain. With that much HP, test pipes make a huge difference, lol. Wonder how high flow cats would do. Thanks for posting those results.

 

Very Nice.. Tim. I got a 350z coming in this week for TT also. And this car already have the straight pipe. Nice to know what kind of numbers to expect. Great job

 

Nice looking Dyno man is that a smoothing factor of 5?

I think the RT's added a gob of hp/torque to my FI setup. It was very noticable when driving and I already had Borla and Borla.

 

tim im telling you if you add the crawford plenum you'll get another 35

 

WOW 35?

Which test pipes are these?

 

I think they are the Kinetix

 

ACP,
Which blow-off valve are you running?? Sounds good.

 

And where did you get this number from?? Any proof that the plenum adds this much HP to an FI setup?? Cause others have said it adds far less HP.

 

Just saw the video. Tim, your car is hot

 

I highly doubt it. What makes you think it would?

 

Did u change the spark plugs to one step colder? The reason i ask is because on the manual it says that changing the spark plugs to a step colder is highly recommended.

 

ACP, great numbers, congrats! You're car is sick. I am going to add the Vertex sides and rear to my car, but keeping the Nismo front bumper. I heard you had to cut up the front for the IC. Do you have pics?

 

kick ***.

 

I am glad everything worked well for you, those are nice numbers.

He is using our testpipes with resonators.

I think that for a FI setup, that the straight throughs are the way to go. either test pipes or pipes with resonators.

High flows show good gains on NA, but you cant beat these numbers for FI.

 

ACP,

How are the test pipe's with resonators? I have the old school LSD test pipes, is there any noticeable raspiness when reving in netural? How about when rolling? Thanks for any feedback you may be able to provide!

The sound is almost no different from stock, I have heard the test pipes and I would go with the resonators.

Aside from the pipes, after seeing and hearing this car I don't know why people are still getting the ATI SC, the sound of the SC just makes me cringe, I'll be saving for the TT, not sure if the Greddy or the one JWT is working on.

 

well i admit i have no dyno proof just logical thinking...if the craford plenum add 20 whp up top on the 350/g35 by correcting a poor design that resulted in a reduction of air flow to one bank than...forcing more air into the engine is still going to have the factory restriction...correcting this should prove to provide even greater gains on a forced induction car than N/A...think of it like exhaust if a stillen free flow exhaust add 16 whp to a Z it stands to reason the gain would be exponential when turbos are added

 

You should hear the Vortech kit - it is a LOT quieter compaired to the ATI kit.

 

The Stillen kit is also quieter than the ATI kit.
