Un huh.

Explain your chart then....



#1...When horsepower and torque are graphed at the same rate, they cross at 5252 rpm. Yours cross at what appears to be 5600 rpm......definately NOT in the 5252 range.

#2...A spike or dip on one line will show up on the other, so the dip in torque from 3500-4500 rpm should show a dip in hp as well......you show a RISE. There is also a dip in power from 4800 to 5200 not seen on the torque curve.

#3...Power does NOT climb at high rpm like you show. I've seen enough Quad 4s in enough different stages of build to know that they ALL fall off.

#4...The number on the chart says peak power is 213 hp, how come the line appears to be a min. of 220 hp?

Remember HP = Torque * RPM/5252.

Shall I contiune?

Umm seeing as I pointed out HP and Torque always cross at 5252 and it didnt match, on Bstuff.. anything else you learned from me? HP and Torque DO NOT rise in correlation to one another, that just rediculous. Furthermore, if you have ever seen as many "quad4s in various stages of buildup" and as many dyno charts as you claim, you would now that the chart itself isnt always accurate, the numbers at the top are all that matter, and the numbers on the spreadsheet... :rolleyes: Wow your a real pro :rolleyes:

[Fat Matt]

Um, actually, I kind of have to agree with him.

Hp is based mathematically off of torque (it's simply a way of showing the WORK that torque does), so the lines WILL always cross at 5252rpm *IF PLOTTED ON THE SAME SCALE*. In addition, that means that that midrange dip in torque should be matched by the power flattening out somewhat.

Look at this:



It's a dyno compariosn of a stock Quad vs a Quad with a full 2.5in mandrel bent exhaust. Notice how the torque on Quads dips from 3300-4400rpm (they ALL do this in stock and modified form that I've seen). Notice also that in the same period of time, that the hp curves' rate of climb flattens out somewhat. Sure it's still going up, but it does it at a slower rate. Just the same, any spikes or dips in the otrque curve will be reflected in the hp curve and vice/versa.

*Your* chart does NOT show that.

I DO notice that the blue line says dynorun.001 and the other is dynorun.003, but overlaying a torque curve from one run with an HP curve from another is kinda goofy (and suspicious).

Here's another example (it's Canada's dyno chart actually from when he compared a stock airfilter, to a K&N to an RSM intake for his 3100).



Notice the torque dip on the green line at 59mph (around 3950rpm if my calculations are right). You also notice that it's reflected in the hp curve. As I said..............a dip/change to one is ALWAYS refleceted on the other.

Also, exactly WHAT do you have done to your Quad to GET 213whp (and as Canada said, the line shows closer to 220, while calculating it off the torque figure shown at 7400rpm gets another figure yet...........)? You must have some VERY hot cams in that thing to pull that kind of power out of a Quad (that's 60+whp over stock). Aaron Choate has a CAI, TB, ext. honed IM, headwork, W41 cams (not that hot I admit), 11:1 compression, ported exhaust manifold, 2.5in exhaust and a Bilmar chip, and he's only sitting at 185whp@6800rpm (since it's fully broken in), and his DOES taper off past 7000rpm.

Somehow I don't see a 4 cylinder getting remotely close to 40whp (@7400rpm) from a set of streetable cams (or even cams that work with the stock ECU at all).

Like Canada rather bluntly pointed out, your dyno is pretty suspicious looking.

Care to explain somehwhat?





I'd also like to point out. Canada is a pretty BIG farmboy.............he's 6'6"........

:D

Just so no ass kicking goes on............

[Fbod383]

Who cares how "Big" someone is.. And I'm 6'5" 230. so what... and I've been around the block a few more times than you kids. Thats odd that you use this "Aaron Chaote" character, even one of your bel;oved Beretta owners got 180hp to the wheels with nothing more than a few mods... Rex... and whoever said my car was streetable!?!? LOL Use the damn search button

[Fbod383]

and explain to me how the hell you make an overlay of a digital chart?

[Fat Matt]

You make it using dynojet's run viewer program.

Just like Canada did.........

Also, the first chart I posted above *IS* Rex Weatherfords chart. It's his first pull with just his ported exhaust manifold and a 2.5in mandrel bent, side outlet exhaust. And he only got to 167whp with a LOUD exhaust, NO airbox and by pulling ALL his accessory pulleys off (which resulted in a 14.8XX with autocross tires). The cams (which he got later) may have put him close to 180whp, but he never did dyno them. He's since gone turbo and is sitting at @225whp.

Either way, you STILL haven't explained why your torque and HP curves do NOT match up with each other. IS it in fact two different runs overlayed?

Again, I'd LOVE to see your car (GTZ or GA) and it's setup (and you ARE close enough to make it happen)............

[Canada]

Actually, I would like to see your car too..........and then we FIGHT! :D :p

As for me, if your GA was the white one with the blue stuff on it, I never did get to race you. Tried once though, but you turned off right by Audio Plus (to your place I'd expect).

I'll have to look for a Black GP to go prey on now.............

So if you see a little white, boxy Sentra, or a maroon NX2000 trying to mess with you at a light, be ready to see Nissan tailights :D

;) I'll be ready for ya


haha yea i live right up the street from audio plus and family video (on franklin) and the prelude was an older one, with really crappy taillights that looked foggy... he saw my bullseyes :eek:

[Blk04GP]

man my net's been down for awhile.. wtf happened here :D :D dude everyone knows Fbod has the fastest quad4 in the U.S. so just bow down :) :) *although sometimes i ponder his existance, let alone his car's cause he never has come to any of our meets...*

[Fat Matt]

Actually "KillerQuad" has the fastest known Quad (it's an 89 GA with a BIG shot of N2O IIRC) in the US. It runs into the 12's........

Aaron Choate and Rex Weatherford would also be VERY close as the are both in the mid 13's (although Rex's car currently needs a rebuild).



Nonetheless, while I'm hesitant to straight up call bullshit or anything, there are a number of fishy things going on with FBod's dyno chart.

I just want to see (and hopefully ride in) either one of his cars.......

Whaddya talkin about.. I have been to two of them!!! whatever happened to the kid from pella that had the Green GT sedan with the white stripes? Last time I saw him, we swapped rims and then he bashed one in on the way back from texas... Ask Chris.... hes seen the "phantom car" hell he even helped me put my "race" mandrel bent exhaust on!! :rolleyes: Instead of explaining everything.. just come and see them, But first I need to put a back window in the retta :rolleyes:

[Fbod383]

BTW Jake (killerquad) and I have raced a few times.. and his car is a 91 :p
