1 hp equals to 0.7456999 Kilowatts

Well what I gathered, was they have installed a few themselves and done there own dynos and gotten some good gains (5-10 at least), but they are in Cali and I am in Texas (weather/humidity/etc.)

% gain should still be similar. If the weather was a factor, it would be a factor in the baseline as well as the final dyno for both sets.

Which by % would have still gotten the same gains if you had the car and the intakes dyno'd in the same type of climate. So there has to be some other factor that contributes to such a loss. Just to add to what caravan said

yup, they may have dyno'd 10 hp higher on baseline than you (assuming same dyno type, but worse conditions for you), but then you would assume that if they made 8 hp, you should make 7.

Well the major change from each dyno was the AF mix, stock was around 12.5 while with the intakes we were down in the 11-11.5 range.

:gtfo2:

if thats the case, those intakes are making you run rich, robbing you of hp and gas mileage. Sounds like their tube diameter is effed up causing the mass air flow sensor to read that more air is coming in than is actually coming in, and is dumping extra fuel in.

so you would have been running a little leaner which would have contributed to a slightly higher dyno, not lower. Nothing too significant but I would think it wouldn't have dropped.

don't listen to rreign, he doesn't even have a Z :rofl2:

lower air to fuel ratio is running richer

I was talking about the car's initial dyno. But after reading that, I can see the confusion. Yeah intakes would have cause the car to run rich where as the intitial dyno w/o intakes was leaner. That's where I was going with that lol.

ahh, ya it sounded like you were talking about the intakes making it run leaner.

technically, a good intake will make it run a little leaner, but not to the point that they risk detonation

Or in my case....a dead cat. I guess you could say...I had a real "Cat"-back exhaust for 24 hours.

Yeah, ok, fine...I hear the chirping of the crickets. :mad:

as long as you hear them you are forgiven :icon23:

you're right on that. I mean ultimately I have read/see/learned that the best AF mix to try to reach is between 10.5 and 11.2 giving you the best output w/o risking some kind of interior destruction. Or maybe that's just with FI. Can someone clarify that?

This actually made me laugh out loud...

well maybe not quite out loud...

actually it was more like a chuckle....

In reality I just breathed out...but at least it didn't make me stop breathing!! :tiphat:

:icon18: At least I knew it was a bad joke....I hopefully saved myself from being self :owned: this time by admitting to it!

For our car (or any NA car) you want around 13.

doesn't change the fact that I've done more research and learned more about the Z than most of their owners:icon23:

FI is more prone to detonation. I haven't looked in a long time but I thought ideal A/F ratio was in the 13's somewhere, with 14.2 being the absolute max lean you can go. I could definitely be wrong though, it's been probably 6-8 years since I've had an A/F gauge in my car

this is true, and I :tiphat: to you!

You have no idea how long I've been waiting to use that, too....its sad. :icon14:

So that is just FI then?

you are stuffing a whole lot more air in the combustion chamber with FI, so I could believe that they need to run with a lower A/F than NA to keep the car safely detonation free...but I don't know the numbers for them off-hand

Yes, for FI you want to be around 10-11 I believe.

I was just having this discussion with a couple of guys the other day. One is a buddy of mine fresh outta UTI and 2 other guys in their 60's/70's with over 50 years experience. Those were the exact numbers I was given by them but we were talking about different motors. Some good ole american muscle, the 2JZ-GTE and the RB series motors.

hey gais

sup

hey cow, any news on the diffuser?

:hello:

Nothing. Tracking number still isn't working. I was out of commission yesterday. I'm sending an email now.

good morning ><'

eh

left a post on forgestars blog yesterday telling the guys looking for 18's that they might be waiting a while since I've been waiting 10 weeks for my order for 19's. Moderator deleted it

just tried again, I'll bet it gets deleted again

Wheel Collection | Forgestar Custom Wheels

I think the time to play nice guy has long passed....tell 'em like it is now Cow, that they are BS'ing you around and you aren't going to stand for it.

Yeah bro, that would be pissin me off. 10 weeks for some wheels?! I know they are a new company and probably have a bunch of shite on back-order but atleast be courtious enough to contact the buyer and let them know if any progress is being made on your order.

Yeah, I thought that after I sent it. I'll see what happens today & then I'll come down hard.

oh lookie lookie

Granted, he should have it, but whatever. Let's see what happens.

he's stalling...

agreed.
