I would agree that the pure Garrett gt3037r is not a laggy big turbo. But, your 200whp statement is NOT TRUE. I can frustrate a stage 3 owner all day at lower speeds due to almost immediate spool up and instantaneous boost response between shifts. It is not until the end of third gear (on race fuel) that the Stage 3 starts to walk away from me. This dyno (sorry to post it again friends) is of a Vishnu Stage 3 vs. a Vishnu Stage 1++:



Also, I'd be happy to race any regular stage 3's on pure 91 octane. You'll lose. On 91, you have all the lag but with only a 30hp advantage.

 

Bizzump for results of 3037 stage? on pump gas....

 

eh, thats not what the charts i compared looked like. although, they were DD dynos not dynojets. on your chart, the stock turbo hits 200hp 1000 rpms sooner than the 3037.

and 4th gear is long, if you are being caught in 3rd gear.....sounds like a pretty lengthy loss in the quarter.....

best 1++ ive seen is a what, 11.9? stage 3 is closer to 11.0, right?

 

Downshift.
I want a 3037. Badly.

 

The lowest times so far on a stage 3 have been on the Vishnu shop car. As far as customer cars, the fastest one so far would have been from Evotomig who ran, IIRC, a 11.5 on a GT35R turbo. However, his turbo was not a Vishnu setup. Other than that, no one has really hit the 11's with a stage 3 kit. At least not that I know of.

 

well, how many stage 3 kits have been sold and installed?

are you saying that people are running this kit and can't get into 11s? or are you saying you don't know of anyone who has run it?

 

Don't get me wrong folks. I love the stage 3 and still think about getting one. The top end power is intoxicating (almost as good as beer ).

However, if you think the tradeoff is minimal, you are wrong. Seth, when you say all one has to do is downshift, you are only right to a point. In the everyday, non race track world, If I get the jump on a Stage 3, I can usually pull away and then hold them off for a long enough time to "win," even in fairly long stretches. By the time they are spooled up, geared up, and on boost after a shift, I'm far enough ahead that it is time to shut down.

At 3500 rpm a 1++ has 90ft lbs more torque. The stage 3 is barely over 150 at that rpm. That is driving down the freeway and not needing to downshift into 4th at 65mph to pass a Toyota Tercel. Maybe I'm lazy, but I don't like downshifting all the time. My tranny doesn't like it either.

Also, you are looking at 4,000 more bucks than the 1++. That is coilovers, sway bars, wheels, tires, headwork, take your pick.

 

Of all the stg 3 kits that have been installed and tuned, I think IE is the only customer to have run it at the dragstrip. I dont know why... but that's the way it goes sometimes....

Someday when I can slip $4000 out of the bank without my wife knowing (read: never), I'll take a few dragstrip passes in my stage 3.

Seriously though, I do plan on doing it down the road and saving over time. By then, though, I'm sure a lot of people will have run theirs. I need to jump on a clutch and injectors to lay groundwork for that big sucker 3037.

 

well, smoggy, im familiar with bigger "laggy" turbos from upgrading on my Z. this shift lag that people talk about generally never had a big turbo car, because it really doesn't exist. not noticably to the human butt dyno atleast.

but either way, i won't be buying it. 5000 bucks over a stage 1+ is just crazy money. im serisously looking into the buschur 20g(if it all pans out)

 

Agreed ^^^. Anyone that comes in here and makes a claim that Stage 3's are slow will be VERY VERY owned in a short amount of time. They are fast, and as IE (in particular) and a few others get up and running, we will see some nice times for such a street-friendly turbo.

 

Really? Just talk to the folks that bought the 1st generation of the Buschur 500 turbo kit. Hell Shiv, you tell 'em. You've tuned 'em all.

However, the boost response between shifts on the top of the line Garrett ballistics type turbos is pretty amazing. And those are what Shiv uses in his stage 3s.

 

well, i don't know what kind of turbo buschur uses.....but, my experience is with power enterprise twin 1420 BB turbos and with a SP71 single supra....the twins had virtually no lag during shifts and the sp71 had a tiny bit.

 

Which turbo was used on the One Lap car and the Thunderhill car?

 

The One Lap car had a 30R. The T-hill enduro car had a stock MR turbo.
