Wow, this just sounds to good to be true! Could it be!??!?!

 

BTW... I forgot to mention the spool characteristics. Not because I didn't think I should comment on it, rather the Rabbit spools so much like a stock turbo that it didn't occur to me to mention it. For what it's worth, I started the pulls from 2500 as to not mask any characteristics of the turbo. Also, all pulls were done in 3rd gear... this is my personal preference since it takes less time between pulls. If graphed by engine rpm, I can lay a 3rd gear and 4th gear pull over one another and there is no distinguishable difference.

If I think of anything else I left out, I will post it. However, if you guys have any questions regarding the testing or results... again, feel free to ask.

 

the numbers look good but without a baseline of the stock turbo on that vehicle its impossible to see how much was actually gained.

 

Great results but dam I wish if you had the MAF on there ....

You have stand alone which in all cases here on EVOm have resulted of 20~30WHP more than using MAF. Is there a way to see results with MAF?

You seem to have great spool on this turbo but in most cases stock turbo have hit 270~280WHP @ 4K RPM where this one hit 250 (NOT bad at all)

3071 was always @ 200 WHP @ 4K which is laggier than both.

More info would be great.

BTW every dyno is different but we have no other way to compare... Have you ran the stock turbo with AEM (Same EVO) on this dyno?

We would like to see 2 charts on top of each other if you can please.

 

Rock on. Thanks for all the hard work guys.

 

Remember he has no MAF... with MAF and stock ECU we would have seen no more than 350WHP which is still better than stock (~320 WHP no cams)

3071 have done the same thing in top end 350WHP with no cams with MAF but ... but this turbo has almost ZERO lag



I think we have a winner here.

 

Do tell. Any surging?

 

I agree with the no maf and the ems. I ain't buying it yet . I am gonna see what some reflash customers get out of her before I start throwing my benjamin's around.

 

Im not the one to be a search **** but you really need to search under "ATP". Hell, go to ATP's website and look at the graphs. Any member who's done the research with tell you that the ATP kits arent that impressive. The stock manifold holds those turbo's back. Not only that, the stock turbo set-up can put out just as much torque if not more than any of the ATP dyno's Ive seen here.

 

Stock manifold is not restrictive at all. You have wrong information.

 

Before everyone starts freaking out about the EMS, just think about it. Last time I checked I didn't see Switzer offer any flashes. I guess he could put the stock MAF back in and tune it with an SAFC but that is about it. Don't forget that Bushur's #'s for the "21G" were on a 2wd dyno and all of his final tuning was also done with an AEM EMS.

 

He's right. The stock exhaust manny isn't that restictive until about 500HP.

 

This would help me a lot. Then there wouldn't be any dyno A vs dyno B debates. We could just see the difference gained by the addition of the turbo.

 

I wasn't implying that the stock manifold was restrictive. We all know that the stock turbo/manifold setup is super efficient and has great potential. What I was saying was that the stock manifold, as proved by Shiv, does not work amazingly well with the ATP Garret GT turbos. I think if one is set on upgrading to one of these turbo's, a header that was made for the turbo would be much more practical instead of running the stock manifold with an adapter. Am I wrong?

 

The SEARCH option always works.
