You suck at math. Dynoflash = 269 whp peak XFlash= 295.5 whp peak which is a difference of 26.5whp peak, not 11. At redline the XFlash made 90whp more than the dynoflash.

 

I don't think I would even bother putting on an aftermarket turbo if I hadn't already upgraded the exhaust completely. You might as well go the extra dime!

 

But you must realize that the flash was a base tune to run safely till it could be properly mapped. This is the first ATP turbo to be installed that I have heard of period!!!! So how can Al tune it out properly without having the car in his hands? It was just a base map to get him around till the flash with the proper engine monitering devices where connected . I am surprised only 26whp more was made over the base line dynoflash with tuning !!!!!! The Atp should produce more than that but he still has the stock cat which kinda sucks he needs to chuck that junk.

 

Yeah, right now I'm not too impressed with the ATP kit, 295 is getting there, but I was hoping for low 300's. From ATP's website:
He needs to switch out that cat. Hows spool up?

 

The cat needs to go!!!!
Spoolup is about 600rpm slower than stock.

UPDATE: 315whp on 96-98 octane w/ Xede.

I just saw in the other post ( https://www.evolutionm.net/forums/sh...threadid=85629 ) that you're running crap 91. I really feel for you guys sometimes. When you put the exede on, you should throw some race gas in there so we can see a proper 93 octane tune.

Edit: Your about 30 secs and one step ahead of me

 

I calculated the octane and it was at between 97 and 98. We were all wishing Az3ar had brought up some good C-16. Shiv just finished tuning. It ended up making 323whp on what was otherwise a stock car before the kit. Yes, it had exhaust, but that with that stock cat. Basically, Az3ar picked up a full 100 horsepower with the kit and tuning. Not bad.

With mild cams and and a high flow cat or test pipe he should be able to hit 360whp on 100 octane, so it 's sounding like that 450 crank HP figure is about right.

good meeting you folks today, no doubt Az3ar will have a fun ride home

 

It still sounds like the spool is less than ideal for a daily driven car (at least for me). I want the spoolup faster than stock!

 

I think the numbers are good considering Az3ar is still running the most restrictive part of the exhaust system of his car. I believe the car is on the right track to make some real power w/ a relatively new setup, which still needs some work. Everyone here knows that if you want to make true power on a turbo vehicle, then it is necessary to get rid of the entire stock exhaust and put a good turbo back with either a high flow cat or no cat at all. For example, the Subaru WRX had three cats and in order for a lot of guys to make some numbers the entire stock exhaust has to go.

I think Az3ar will end up filling in the blanks such as cam gears, camshafts, and a cat delete pipe in the near future. I will be excited to see the results of his car running on the above additional mods and some c16 race gas...

 

EZ76, 323 whp on Shivs dyno is close to 450 crank and approx 370whp on an average dynojet . ATP reported 425 crank hp on pump gas with just an exhaust. That is why there was such high expectations not to mention the report of stock like spool-up. My question to Shiv and company is with stage 1+ with a bigger front mount,larger injecters, and a custom manifold is this thing capable of putting 380whp -400whp on race gas on the heartbreaker dyno. If not is the 3037r a better option. Also what was the spool-up difference between the 3071r,3037, and the stock turbo. OUT!

 

Oops Atp reported 450 crank. My bad. I believe 375 whp on their dynojet.

 

My take on the 3071:
The kit is laggy; no doubt. 200-300 rpm slower spool than the stocker is a pipe dream. More like 600-800 if the cat gets deleted. (w/ the stock cat it spooled close to 1000 slower;pretty much like the 3037)

However; considering that the exhaust was choked up, cams/camgears were stock it did not do too bad.
As EZ76 mentioned in another post, 350-370whp is not out of the question on racegas w/ those items rectified. About 310-320 whp on 91 pissgas.

The question is this: is it worth $3k+ to gain that much power w/ substantial lag??? If you have to put w/ that much lag why not go w/ the big boy GT35?

BTW
Nice meeting all of you guys. Smog, nextime we'll find the beer.

 

Well, we all know that Az3ar had a few less modifications than most of us have on our cars. For instance, if the cat was removed or replaced with a high-flo model...backpressure should be reduced and the spool should be faster. Do you think that this along with cam gears and possible cams there is a possibility of spool being reached within 300 rpm of stock?

What boost was actually being used in testing? was it still 20 psi??? Was the gains realized just from the efficiency of the turbo design or was more boost pressure a factor?


Was there any intake charge temperatures recorded of a stock EVO as compared with the ATP model? I realize different times on a dyno can be different, but the delta T should be similar.

Do you think that ATP turbo has purposely mislead EVO owners regarding the capabilities of this turbo? They claimed that they had used only a cat back exhaust and achieved spool 200-300 RPM above stock and 375 whp. I wonder what EMS was used for those numbers? MAP instead of MAF??????

I am just curious of opinions of the people that seen it with their own eyes.

Thanks in Advance for all of your opions. ATP may have another sale if I can get warm fuzzies about the 3071R's capabilities.

I guess patience is a virtue. I will look into the 3052r from another company. It sounded like it delivered the goods.
