Drew made 412whp

 

Nice numbers!

I dynoed at 326whp/380wtq on low oil. So i'll re-dyno soon.

I was expecting higher numbers, but every 335 there dynoed around 330whp.

 

Yeah. . .you're piddly 475 ft-lbs and 420 HP were pretty sad.

 

I heard Drew turned up the boost on his third pull to get 412... Cheaterrr!! :-D

Seriously though, our cars were extremely similar im very surprised.. well i guess it would make sense since we have pretty much the EXACT same setup down to the injector size and brand lol.. at around 8ish psi we made within 2hp basically lol

 

Thanks Buddy! I hope to see you at some more get togethers... down in tacoma and west seattle if you get me. I was all alone with the domestics last friday man!

 

Yeah, the numbers aren't bad, but with my mods I should be at 465 hp/485 tq. I've seen probably 25 cars with the exact same mods as me and they are all right there. If the SAE correction was at .98 (which is was the last time I had it on the dyno) rather than .95 it would have made 430/484. I don't even know what the SAE correction is supposed to be. Time to talk to my tuner....

 

if i do that, i get the numbers i thought i should be making...433rwhp

 

Hey, what's happen'n guys. I'm a day late, but just wanted to say thanks to Patrick for setting the dyno day. To Flea7, thanks for taking a bad pic of me and posting it lol. I'll get you back for that one. BTW, nice meeting all the guys yesterday.

 

How much did you put down?

 

412rwhp

 

Yeah, and again, I don't know if I'm doing the math right...I'm just assuming.

But it seems more "right" to me. Like the guy with the G37 was hoping for 280, and if you use my method, he's at 284...

(And with my car, puts me right where about 100 other people with my mods are...so that makes more sense to me)

Overall, doesn't matter, as long as we use the same .95 SAE each time, I know what's working and what isn't...just not as good to brag with! haha

 

STD = 362.03 Hp / 322.30 Tq

.95 SAE = 343.92 Hp / 306.18 Tq

 

I don't mean to be a complete tard, but what does a "95%" correction factor supposedly correct for? I mean specifically, how is the value 95 chosen? Is it a generic means for accounting for pressure, temp, humidity, O2 partial pressure, etc? Isn't correction merely supposed to keep all (same brand) dyno's standardized? Huh. . .

I'm bored, and thinking about all the different dyno's I've done. All dynos were with the following mods:
1/2" motordyne spacer, borla exhaust, z-tube, pop charger, and tuned/flashed by Tadashi at technosquare. (see this post for my dyno "log."

Just doing some scratchpad math, a decent shape '03 5AT VQ (280bhp/270btq) should put 218whp and 210wtq (22% driveline loss).

So, comparatively, all are on Dynojets:
Dyno 1, Costa Mesa, CA, June 4th, 2004, ~50,000 miles, 2 weeks after install of all mods above, 3rd gear, let off at 6600 RPM, tank o' 91octane:
run 1: 245 HP, 221 TQ, Temp ~75*F, Baro 29.91
run 2: 247 HP, 224 TQ, Temp ~76*F, Baro 29.91
run 3: 248.5HP, 227 TQ, Temp ~76*F, Baro 29.92

Dyno 2, Lake Forest, CA, June 5th, 2005, ~65,000 miles, same mods, 3rd gear, let off at 6600RPM (6 gal. 100 octane, ~2 gal. 91 octane, ~97.75 effective?):
run 1: 211 HP, 195 TQ, Temp ~88*F, Baro 29.66
run 2: 217 HP, 197 TQ, Temp ~88*F, Baro 29.66
run 3: 215 HP, 196 TQ, Temp ~88*F, Baro 29.65

Dyno 3, Auburn , WA, January 20th, 2007, ~111,000 miles, same mods, 3rd gear, 4th gear, 4th gear, let off at 6600RPM, 3/4tank of 76 brand 92 octane:
run1: 222.53 HP, 212.81 TQ, 53.81*F, 30.16", 42% humidity, SAE 0.95 (234.24 HP, 224.01 TQ STD)
run2: 218.07 HP, 211.57 TQ, 54.03*F, 30.16", 42% humidity, SAE 0.95 (229.54 HP, 222.70 TQ STD)
run3: 227.77 HP, 221.21 TQ, 54.75*F, 30.16", 42% humidity, SAE 0.95 (239.76 HP, 232.85 TQ STD)

I'm pretty sure the dyno 1 or dyno 2 guys didn't use any STD/SAE correction factor, but I'm also sure the dyno 2 guys didn't know jack about their own dyno. Taking the average of the dyno 3 (needs oil change, cleaned air filter, probably shoulda done an ECU reset considering all the granny driving I'd been doing, just to see) and comparing it to the freshly tuned dyno 1 leads me to believe that my VQ is holding up pretty well over time. I'm going to do a compression and leakdown check prior to my vortech install, so I'll let everyone know how it goes.

Carry on, gentlemen.

 

Hopefully Bob or someone can shed some light. I'm not entirely clear, either. Looking at my last dyno graphs from 8-Velocity, they were at .99 SAE correction.

 

Who was the white 350z that spun out as they were leaving?

 

lol...there was a white or silver one that did the same thing at a Sykart meet July 4th last year.

 

That was all Drew... lol

 

that was purposeful drifting

 

doesn't sound like it

 

lol, redlude was the talking about the white one that did a 180 on the main road on accident at the dyno day. I did a big drift in the parking lot of sykart on 4th of july, and carried it all the way out to the main road. I didn't spin out (that time at least).
