Here are the final results of the super controversial ATP 3076R Turbo Kit. We tuned the ATP turbo on 93oct, and at the same boost level as my baseline IX stock turbo graph.

Next we retuned the turbo for 100oct and 26psi. Using the same logic as the first test - and overlaying on my 382wtq stock IX turbo curve.

The point of all this was to compare the ATP turbo to the stock IX turbo - at the same boost levels, in basically the same conditions - AND at two different stages, high and low boost.


To get to these numbers on the IX, this is what I did -

Mods:

• Denso 720cc Injectors
• Walboro 255 FP
• Megan Manifold
• ATP GT3076R - .82 AR

STEP 1 - Porting
I ported the ATP turbine housing and did some minor porting to the Megan manifold (head side)

BEFORE




AFTER I didnt install that gasket!




STEP 2 - Install

Installed the ATP Kit, 720 injectors and Walboro FP








And those of you with a keen eye will pick up on why I chose the Megan header - to bolt up to the ATP housing





STEP 3 - Tuning

Had Doug @ TopSpeed tune the car



Results! - 23psi, 93oct

At 19psi - the car made 370hp. Basically untuned. It was amazing! We then moved to 22.7psi and Doug worked on the fuel maps. He then went to work on the Mivec. 10 pulls later and the ATP Kit put down 416whp and 342wtq!! Is that not one meaty torque curve? It holds the power so nice all the way to 7K. So much for the ATP housing being overly restrictive!






STEP 4 - 28psi, 100oct

We then did some crazy tuning with the Mivec turned off. Wow! It changed drastically - and not in peak hp or torque curve changes - but something we had never seen before. (more on that later). It was very shocking!

Anyway - we turned the boost up to 28psi, added 4gals of C16 and remapped the ECU. The ATP Kit easily went to 486whp and 411wtq!




We picked up some lag - but its directly related to the turbo spooling up higher than on the pump gas map.


STEP 5 - Stock Turbo v GT3076R - 23psi, 93oct

Next we overlaid my IX Stock Turbo Graph - at 23psi. The results are very impressive!! Although peak torque stayed the same - there was a 65wtq difference at 6.9K. After 4.5K we blew past the stock tq numbers. GT3076R in RED





STEP 6- Stock Turbo v GT3076R - 28psi, 100oct

Then we overlaid my IX Stock Turbo Graph - at 28psi. Again - really, really good numbers. This time a 80wtq improvement - at the same boost level. GT3076R in RED






STEP 7- Scorke v SmokinJoe - 23psi

For sh*ts & giggles - we overlaid Scorke's (Sam's) 23psi run - and his AMS GT3076R kit and his old 2.0L with my 23psi run. Scorke is in the BLUE. Look at the difference in spool. The ATP with the .82r housing spooled better than Scorke. And it made more power - across the entire curve. OH SNAP!

To be fair - this was Scorke's best dyno run on his 2.0L that Doug could find. We weren't biased or trying to be mean to Sam (seriously! haha). Also, look at our a/f curve - its identical.




STEP 8- Scorke v SmokinJoe - 28psi, 2.3 v 2.0L

Again - to be fair - we then overlaid Scorke's 2.3L run against my 2.0L run. I think he may have been at 30lbs according to Doug. Either way - clearly you see the benefit of the 2.3L. Scorke is in the BLUE again.
Hopefully he ego isnt so bruised now.

But hey - look close and you'll see we catch up to the 2.3L by 7K.. I know..like it maters






Not bad results at all. I am very pleased!

 

Awesome work!

 

nice write-up...

glad to see you were able to make some solid power...

 

Nice job.
Love the port work...really helps with smoothing things out and broadining the powerband just a bit inconjuction with the header...

 

Wow, very impressive. Unfortunately I cannot view the graphs. Where did you hit full boost @ 23psi and 93 octane?

Also, what do you think your total investment was into this project?

 

WOW! That is very impressive. Where is the bozo that claimed he had never seen an ATP kit make more whp than the sotck turbo? From 4600 rpm and up, the stock turbo is loosing ground.

 

Yea no kidding but thkz for this unbiased test you did I have always thought that for the bang for the buck I'd go with an atp but if I where a rich kid like some then fine ams or buschar but its nice to see how they compare great work man.

 

Very nice number. Topspeed can do some crazy stuff from what ive seen. Do you know Charles? I live in Kennesaw near you. Id be interested at taking a look at your setup in person if theres a meet around here. Sorta looking for a good street/road course setup and i dont want something laggy. Do you go to the Varsity meet? Congrats on the numbers BTW.

 

Looks good man! Good job with everything - install and power it's making look top notch.

 

Glad everything worked out for you man. Especially since you got such a good deal on the kit.

 

awesome, can't wait to dyno at topspeed friday!

 

nice post! i had my 3076r tuned on 93oct 2.5 years ago and i made 376whp and 324tq at 22 psi you beat me in power by alot!

 

Haha! Yeah - there were a lot of those. I got some nasty PM's too. Because the ATP housing wasnt divided and it looked really different, far more different than anything on the market - it immediately got a bad wrap. Without looking at other factors - a lot of naysayers were quick to point out that it was a bad, laggy design.

There are a lot of things that contribute to HP, or lack thereof. And it was these things that got me thinking. Maybe the porting did the trick. Or maybe taking my time on the build and ensuring every bolt was torque'd down. It took me 2 days to install it - working about 4hrs each day. That's a long time! But it paid off in the end.

Thanks for the kudos!

Maybe later I'll show you what happened when we turned the Mivec off.

 

Great numbers Joe, ::waits to see what scorke has to say:: lol.

Looks like the ATP kit may be on my future upgrade list

 

I love it. Shows how stupid the internet can be. So many where under the impression the turbo was junk just from looking at it. Maybe you should send your results to ATP. They deserve to get a boost in their kit sales.
