370z Nismo Dyno after CBE/HFC Upgrades

Matt · 07-07-2010, 03:03 PM

I just wanted to share the Dyno that I got done this past weekend at Z1 Motorsports with the other Nismo drivers out there. The top cars in both N/A and FI categories (only ~20 cars though) were both 370z Nismos!

My Nismo has Berk CBE and Berk HFCs installed, but you should have similar gains with other CBE/HFC combos such as Stillen or F.I.

I did not have a baseline done, unfortunately.

That little drop at 4.9K is curious... must be due to VVEL.

Thanks for sharing man. I was looking into getting those mods.
I'm looking into getting an injen SP dual CAI specially built for the Nismo and got a +13 whp jump.

Awesome!

Jordo! · 07-07-2010, 06:28 PM

Yeah, didn't mean to diminsih the results or anything -- great numbers!

What makes you think that? I would chalk it up more to a glitch than anything else... if it was a VVEL thing I think we'd see it in more dyno sheets than just this one.

Anyways, nice numbers.

Boost_lee · 07-07-2010, 08:43 PM

I was thinking the same. More likely a bug that occurred during the run.

Great numbers!

Matt · 07-07-2010, 11:38 PM

I don't know what that little dip was, I'm assuming operator error or glitch. I had a few pulls and this run was the only one that had it.

Don't put too much into the gains from the intake in addition to my mods. It's been proven that the first exhaust/intake mod gets around 12-15 whp and the rest, not so much.

So Intake first? Probably 13whp, sure. But after Che/hfc, probably no more tha 5-7, and that'll be at the top of the rpm range. I could be wrong, as I'm no expert. We'll see once I get my gen3's.

nice numbers. im going with HKS filters and HFC's. i hope to pull numbers close to yours. congrats.

A sudden drop in power like that makes me think it's a suboptimal switch point in lift.

I could be wrong -- just speculating...

Could also be wheel slip on the dyno.

Jordo! · 07-08-2010, 05:05 AM

^^^ True, true. If it only happened that once, it was probably wheel spin.

Imma let a little cat out of the bag

In a couple of months, one of the tuner mags is gonna have a rundown of each individual intake/exhaust mod. A shop I deal with did the testing. They took each individual component (CAI, HFC, CBE), installed it on a 370Z and dyno'd the vehicle. Each component was dyno'd separately.

A can tell you this: HFC's provided the most gain out of all 3 components.

370Zsteve · 07-08-2010, 06:23 AM

Matt, how come they didn't pull up to 7500 RPM? You would have had slightly higher numbers for sure!

Nismo_370z · 07-08-2010, 08:43 AM

I just going off the theory, NOTE: im just a beginner and just learning as I go, But the whole purpose of having A CAI, HFC, CBE is to increase fuel consumption and efficiency of the combustion engine. But the goal is to tune the car with the best combination of the three, to have the fastest acceleration...

SO you could do a rundown of each individual intake/exhaust mod. But what they should do is give a rundown of each possible combination...and find out which creates the best efficiency. I'm visualizing an internal combustion engine as a chemical reactor. The rate of reaction depends on the rate of Oxygen/fuel ----> Products, CO2, CO, POWER...ect.

So the current dual air intakes may be sufficient to supplying air to the engine, but a dyno CANNOT correctly simulate the airflow into your intake at say 80 mph on the highway. So how can you say that the HFC has better results when there are more variable to be evaluated under the correct conditions.

Sorry to beat this into the bush but this really interests me.....and should make a good discussion...
