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

[digitalsolo]

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.

Seems like you're a whiny bitch, really.

Last I heard this was a run what you brung event.   Maybe next, go faster?

Did I not tell him this was the wrong Forum to toll?  Bunch oh crying it sounds like. 

but to answer his smart ass question about my formula I will just answer it with his same answer.  I used my knowledge of the LS platform and the turbo FD's we have seen to come up with that figure.  Chough nick want to chime in here?  Now go home we don't want you trolling here.

I can't say what boost Mike was running for sure, but these guys sure seem like they're mad that somebody stepped on their junk at this event.

There's always somebody faster.

[Sabre002]

Blake I bet he has a exotic car?  We ran into some of them at VIR this year they don't like it when a RX7 slaps them around lol.

[digitalsolo]

Kinda like when Porsche guys get beaten by a Spec Miata?

[Sabre002]

hahah yes.... we had some of that this last weekend.

Self Affliction-  You are responding to a thread from November 2012; however are arguing about the race that happened in Spring 2013.

If the engine makes 500rwhp/450rwtq all motor and you add 4psi its around 625rwhp/600rwtq.  At 1 bar (14.7psi) it should make around 1000rwhp/just under 1000rwtq.

425rwhp n/a FD's run 126-128mph in the 1/4 with under 400rwtq
450rwhp FD will do low 130's
500rwhp mid 130's
550rwhp high 130's (enuf to run a 9 second pass)
600rwhp low 140's with 550rwtq

So with 625rwhp/600rwtq Mike's car should run a mid 9.   His turbo can make 350rwhp+ more than that at full tilt.
That is 170mph+ in the 1/4.

The RX-7 has a small frontal area.... but similar aero .cd to the cars at the event.  The frontal area is what is allowing him to kick butt above 140mph because he simply needs less power to do it.   My car did it also... above 140mph I would reel in the higher HP cars albeit me with around 550-575rwhp and they had low/mid 600rwhp (supercharged V8 M3's).  I also had a widebody kit and massive tires on it.

If someone wants to be the fastest at the 1/2 mile and 1 Mile shootout events it isn't about having a 2000hp twin turbo Corvette with nitrous like LMR.... or a 1400awhp GTR..... it would be about having the smallest frontal area car with good aero and similar power.  Frontal area is more critical than aero .cd rating.  Traction is also key.

That is how Bill Warner increased his top speed big time with his turbo Hayabusa..... until he died this year.  http://thekneeslider.com/bill-warner-rides-his-hayabusa-to-311-945-mph/    does this bodywork look like a stock Hayabusa?

You take away his turbo, leave the motor alone with turbo manifolds as exhaust and his car wouldn't make anything CLOSE to 500whp. It's an ls9 with 9:1 compression, with the motor exactly how it is without the turbo it'd be lucky to make 370 whp.....adding 4psi will not yield 250whp! And yes I bumped this page because I came across it on google. I wasn't going to search for an updated one to comment on.

You are absolutely correct! There are many variables to consider and that's why I am saying there's no way that car should have performed in that manner on 4psi. More like 15+. I have seen very similar builds and in order to be as fast as this car was, they had substantially higher boost levels.  When I said more like 24psi it was exaggerated but not by a whole lot. I personally think the last run on this car would have been around the 17 or 18psi range, that's based on all my experience around the LS platforms.

10 psi on my last run 193.5mph. I turned it up for the TT ford gt. This motor has never seen a dyno but my last ls3 made max power at 14psi with 23* timing.  People forget that the rx7 does not need that much power to go fast.

I honestly don't even know why you are still talking.  Mike already said it goes low 170 at 4psi and was at 10 psi for the 193 mph run.

He's saying that now but at the airstrip he was not. All he kept telling everyone was 3 or 4psi. Even then 10psi just doesn't equate to how fast this car really was......all the parts just aren't adding up correctly.

It is run what you brung...........at no point did I say I was mad about him being so fast. I gave the guy props, it is a fast car. The thing that is annoying and pisses everyone off is him blatantly lying to everyone, especially the ones that are very experienced in the LS platform, about his actual set up. It's like you watching your neighbor fuck your wife, and then you question her about it and she denies it ever happening.

[Ls1-fd]

You are just too much. Unless you have built a rx7 with a built ls9 engine and run it you do not know anything.  You can not compare it to anything else with the same motor. The same motor will not run the same in any other car. I have raced other cars in the mile before and they need 3-400 more hp to run the same mph. So unless you own a turbo ls9 rx7 you do not know what the fuck you are talking about. So next time line up next to me and I will run 15 psi and over 200mph and try to keep up. And if you can out run me you will not see me crying like this about what you are running.

FWIW, my 5.3L (stock bottom end) with nominally higher compression, good, but not as good of heads and some really mediocre shorty headers did >400 RWHP.   I would think that properly setup Mike's combination should do better than that N/A.

Also realize that not all engines N/A vs. turbo behavior is a linear relationship of boost and power.

Again, I'm not saying that Mike couldn't have had a touch more boost, but 600 RWHP at 4 psi isn't really that shocking to me.   BeasTT's twin turbo car does over 600 RWHP on 6-7 psi all day long, and he's got hand ported heads on a 9:1 6.0 block.   It did ~1000 RWHP on 17 psi without everything really dialed in yet.

A 10:1 LS1 (346ci) with stock heads (260cfm approx) and a baby cam with ls6 intake/headers will make 380-400rwhp on 91 octane.

A 10:1 ls3/ls9 with medium size cam and 360cfm MAST heads, better flowing ls3 intake, and e85 will make close to 500rwhp n/a.   That would be mid 10s on the motor alone in an FD.  Now add some boost.

There is a reason many of us run the rx7.  Low weight, good aero, small frontal area are only a few of them.

See you this fall.  Mike is stepping up his game this next outing so it'll be a lot faster simply due to running a real boost controller and traction control.  Then throw on a bigger turbo on top of it.

Surprising to see that heavy ass Mustang pull on him like that... I'd have to turn it up to 5.

[Speedfab]

It's an ls9 with 9:1 compression, with the motor exactly how it is without the turbo it'd be lucky to make 370 whp

Saying you are a 'tard would be an insult to people with Down's.  You're on crack.  I dyno and tune cars all day for a living, and probably was when you wore diapers and played with Barbie dolls... you could take a pair of rocker arms off that motor and make 370 N/A.

Lmfao was waiting for the other shoe to drop.
