Does the 280 degree cams negatively effect at what rpm the 3071r spools?

 

i only say that the 3071 makes boost at the same time as stock because that's all i've heard. it's a similar to stock size turbo yet it has ball bearing center cartridge. this would make me think (or at least wanna think) that it's capable of spooling just as if not faster than stock.

with all the right stuff couldn't you get full boost by 3200-3400? that's the only question i'm asking... and you kinda answered it by saying it makes instant boost over 3500... well isn't that faster than stock (by the definition i gave already)?

if it's gonna boost slower than stock tit for tat whatever the mods then i guess that sucks... but does that put the final number under stock turbo's full boost with nothing changed (3600rpm)?

also... i kinda say this cuz i plugged ams about their turbo for a long time... they said it can make over 400 on pump and spool faster than stock. that is waht i want... any other takers?

 

the only thing i dont understand is the bad grammar and the broken english, but once we get past that, i think i can understand pretty well.

lets hear your explanation.

 

Ah, you just have to tune him out. He's just a kid.

 

A GT3071 isn't that much different then a GT3076. The only difference is the smaller 71mm compressor wheel. With the smaller wheel comes faster spool, but not as fast as the stock turbo.

 

The answer to this question is "Yes" or "No", depending on the cam timing.

 

oh oh the mad Shiv ... I will leave you guys alone.. After all Shiv did not believe in the WIK nor the 3071 for the longest time .


What’s there to explain the guy put his point in and I agreed with him. A lightly moded 3071 turbo spools better than bone stock EVO (dyno proven). However once parts get added to the stock EVO spools greatly improves..

Nothing to explain but Alex requires so much to explain as he is slow. Good luck with your turbo and your believes.

Alex, I really feel for you bud

 

hmmm... looks like the only choice for me then is the evo9 turbo with tme internals... boost sub3k after all the breathing goodies.

 

Doesn't this turbo push about 50% more air than stock? If that is the case, there is no way it can hit the same boost levels at the same rpm as stock with everything else the same. I think some of the confusion comes from people using the same terminology, but meaining different things.

Question for Shiv or David, At what rpm does the 30XX push more air than stock given stage 1+ mods?

 

He is stating that a properly modded 3071 will spool faster then a 100% stock Evo, considering how an Evo is stock, why not?

My guess is the 3076R is a better choice, that or the TT kit. You need to get rid of the cat, ESPECAILLY if it is stock, it kills the spool and topend.

 

The 3071 pushes considerably more air than stock by virtue of it's 71mm compressor wheel. It's big exhaust housing makes sure that it doesn't easily get choked up with backpressure either. The advantage of ball bearing turbos over standard oil bearing turbos is durability and transient boost response. The latter is very different from boost threshold. Transient boost response is the time it for the system to go from one pressure to another pressure (vacuum to boost, boost to higher boost, etc,.). Boost threshold is simply the amount of boost available at given RPM under fixed testing proceedures. Unfortunately, it is boost threshold that most people quote and tout.

It is rare that you will see a ball bearing turbo make full boost signficantly earlier than a compariable non-BB turbo. But what you will see is a near verticle rise in boost once a certain boost level is acheived. It is this that makes a good BB-turbo so responsive on the road. This is not illustrated in an inertial style, low to high RPM dyno pull. You will not overlook it on the street, however.

The 3071 will not spool quicker than the EVO 16G, all things held equal. Much of the advantage the 16G has over the 3071 is the fact that it is twin scroll which help spool up/response in a very big way.

az3ar has to be the most ignorant, childish, annoying person i have ever seen on this forum. How can one talk so much with so little knowledge behind his statements??? I am impressed.

 

I hear you. Their are pleanty of those in these forums. I wish i could get a can of raid and spray them off of the site .

 

dont feel for me because my believes are different


the last thing i would want to do is to **** off the mighty az3ar.

1) you've already threatened me physically

2) you're brother's already lashed out at me in your defense, as if his serving for the army is somehow related to or a defense for your idiocy

3) im still traumatized by 9/11, so i'll leave and your ATP 3071 alone. PM me next week when it spools.
