Shift-S3ctor Airstrip Attack with Mike's single turbo LSx FD 11/10/12

[zbrown]

I just looked and it was rolling start. That would explain it

I thought it was a standing start type of deal

I was way off, thanks for the correction, lol. In reality psi stands for a multitude of things and not just pounds (of force) per square inch.

You're welcome

In reality we're talking about turbos, where it stands for pounds of force per square inch.

Hell, my old 5.3 did >400 RWHP on 0 psi.   I'd wager my current 5.7 with the same heads is low 500s on 4 psi, to the wheels.   More displacement + better heads and the same turbo on an LS9 should do better than I do.   Particularly if the tune is on and the timing more aggressive than my pansy ass timing I use.

Boost is a combination of a lot of things, partially including resistance to the airflow passing through the engine.   More efficient engine + same turbo airflow output = "less" boost.

[spacevomit]

Yeah. All I'm sayin, ya damn noobs*, is that intake charge PSI by itself doesn't mean much. It needs to be considered WITH at least a few of the other factors.

*Lol not you Blake. Please don't ban me lol...

I gotta kick outta everyone at the event touting how much boost they were running.  Conversations like, "I'm running 24 psi. Well yeah I'm running 30. That guys running 32."  Then they'd ask Mike, "How much are you running?"  He'd hold up 4 fingers and say, "About 4"

That dude is NOT running 4PSI....more like 24psi. I guess he can't count that high so he just puts up the 4 fingers....

You do realize that 24 PSI on a 6.2L V8 with heads that flow 340+ CFM would be like 1200 RWHP right.  You picked the wrong site to troll if you keep this up.

Can I please see your mathematical formula on how you came up with that figure? Cylinder head flow is only part of the puzzle, how about camshaft overlap and events?  Also what about intake manifold flow? Exhaust manifold and turbine housing flow? There's a lot of variables not taken into account right now....

[MyCockAddiction]

Seems like trolling above, but I am too skeptical that 4ish psi making 600 rwhp can be that potent. The FD is light, no doubt, but victories against some of those opponents seem reasonably questionable when power to weight ratios are considered.

PSI is (in a sense) effectively just a measure of restriction. And don't forget the aero factor.

I don't think a difference of  .04 on a drag coefficient is going to be that big of a factor especially when that ford gt has 1000 horsepower vs "ls9 on 4psi" Infact isn't the fastest standing mile car currently a Ford GT? With your logic right now we should all be going out to Texas with Rx-7's with 4psi and stomping their records!

Next event I will have to put in one of the guys above in the car with a psi gauge in hand.

Look, I was at the event and I was standing there when everyone was questioning your setup. I know a few people offered to ride in your car and video your boost gauge to prove to everyone you were in fact running 4psi.....You declined making some excuse. Also I remember we asked you about a boost controller on Saturday and you claimed you had no boost controller installed, but then Sunday you magically had higher trap speeds. When asked again about a boost controller you said you had installed on overnight.

So you are telling me you found boost control solenoids, wired them in, dialed them in to your Holley standalone system, all on a Saturday night in Coalinga California?........Must have went to the K mart to get that.

Dude just be real for once, we all know your car is fast that isn't what we are questioning. It's a sick car and a very nice build. Everyone has just been trying to get you to be truthful about your setup. There's no reason to be doing "street racer hustle" out at the airstrip. By you insulting everyone's intelligence, you turn a fun event into a very displeasing event. People put thousands of dollars into their cars and take pride in what they have and for you to claim such low figures (both hp figures and boost levels) causes people to get pissed. And if 24psi on a ls9 would cause the heads to lift, then you need to learn how to tune a bit better my friend.

My Holley boost controller was not working all day Saturday.  Sunday I put on a manual boost controller so I could run faster times and it worked. I gave out a lot of rides in the car Saturday and Sunday. So Mr Cunningham I have nothing to hide on the car. Next time ask me and I will give you a ride and you can hold the laptop. This setup has never seen the dyno. I got the car running a few days before the event and tuned it at shift sector.

While Ryne Cunningham was very vocal about your setup, this is not him. I am just a fellow racer that was at this event and found this thread so I wanted to clear the air a bit.

Dude you're confused about the meaning of PSI still lol

Good, sounded like Ryan. Next event introduce yourself and I will give you a ride. Last event I still have 200 more hp to use but I need to be able to put it to the ground. This is why I need to get my electronic boost controller working so I can run 15 psi up top. No reason for anyone to be mad. Allways faster cars at events. My car went 196mph in the mile before the turbo was added. So they do not need a lot of power to go fast.

Actually we were talking about the definition of PSI.

[spacevomit]

Fine, I'm not sure I see what you're getting at... All I'm saying is, you can't compare just the PSI, it's not the best indicator of anything unless taken with other variables. I'm not sure if you guys are doing that, but it seems like maybe... You can't just like compare (for example) just the PSI of a Evo and some turbo LSx car, as some indicator of performance, it doesn't tell you much by itself.

[spacevomit]

Speaking of which, neither is drag coefficient by itself the only thing to be considered as far as a car's aero. These are like magazine statistics..
