Keep up with our series on Project Altima. We're going step by step with this car and doing dyno testing all along the way.

First off, I'd check the pump out for sure. Ours had a fuel pump go out at around 9000 miles. Gave some technicians fits until they figured it out. Don't know if it was a random problem or if it could be common to the cars...

I'M THINKIN OF PICKING UP AN ALITIMA 3.5L. I WAS JUST WONDERING IF THE CAR WAS TOO HEAVY FOR COIL OVERS? COULD SOMEONE LET ME KNOW.

The curb weight on the new Altima is 3225 with manual trans. The twinturbo 300ZX weighs in at 3414. I know for a fact that many coil-over systems were developed for the Z.

I'm not really sure if there's a huge market for coil-overs for a sedan like the Altima. Only time will tell. What you can count on, is a peformance tuned strut/shock with a lowering spring at a higher spring rate.

Which is the exact combination I want once the strut/shock aftermarket catches up...

I'm curious to know where you plan on getting the nitrous setup from? More importantly who you have to handle the engine management. The fuel system on newer Nissans like the Altima is entirely controlled by the ECU. So you can't simply raise the fuel pressure for the Nitrous with something like an HKS super AFR.

I'm 99% sure the JET computer chip you refur to is for the older Altima

I know of a memeber (different board) that has a Nitrous Express Wet Nitrous Kit setup since no fuel return on the 3rd gens.

I'd be interested in seeing the dyno chart!

The file was curropt so some PhotoChopping was needed to clean it up.

Without knowing more about the car I'd say this smells like BS. 380 ft lbs of torque! I'd like to know how they are dealing with the fuel issues that we've discussed today.

Slurp or myself will get him over here to post...

That spike in torque is pretty odd in the beginning.

So the system is activating at 2500rpm?

A wet system is the only way I see it working right now. Just wondering how the timing is being retarded though?

He has the switch on the steering wheel if I remember correctly so he can light it up at any time. As for retarding the timing, he isnt doing anything.

Don't get me wrong if the car is truely making more power than good for him. He's definitely not running on crappy California 91 octane that's for sure.

Wow, that's scary. They must be just dumping fuel in there.

There's definitely something not right with that torque peak in the beginning...but besides that it looks pretty good.

besides that spike in the beginning I'd believe the hp and torque are possible on pump gas with Nitrous.
