Whoa - 64* dyno temp is still GREAT conditions...9whp?!

Did you run the map that shiv made for these turbos?

No i didnt run the upgraded map for these just the same stock turbo 1-21 map... I didnt get an upgraded turbo map for the 1-21 from shiv, i'm not sure if he released one. Air/fuel were identical but Clap i think i may need to log cause there might be timing being pulled but i'll check this for you tomorrow cause its raining now.

[Clap135]

It looks liek you ran a upgraded turbo map cause the boost remained flat till the end of the pull. and i know for a fact the stock turbo does not have any trouble holding 15psi till redline. You def need to do some logging and talk with shiv, cause this is a little disappointing.

The only other thing i can say is that on the new runs the oil temp was 245-250 compared to the stock turbo runs that were around 210 because of the ambient temps.

That wont matter, you need to up the boost and talk with shiv. More importantly we need logs.

Ok guys i'm gonna try getting logs tonight... Whats a safe max boost level to run? 16psi?

My off the top math says that if correction was used the difference would be about +6% for the AWD turbo, which would be 381hp, or a 30hp gain.

Overboost, Do you happen to have the dyno files and can run both though corrected?

Are you on autotune maps?

I still run the old FW and Maps because it has auotune. I'm not using Shiv's DIC at the moment.

You should be OK with 16.

So you used Shiv's Dic before?
lol sorry, couldn't help it.

Neither were corrected... and no i dont have the files sorry guys... i just go a print out each time and scanned it.

No not running the autotune maps... the 1-21 maps have autotune disabled. Since air/fuel ratio was the same i'm guessing that the only difference could have been the ignition timing.

Yeah I know niether were corrected. I just used the temps and did some off the top math to estimate what the difference would be if SAE correction had been used.

Its a bit too wet outside to log... in this weather 4th gear wouldnt hook up so i won't bother trying until tomorrow. What i can say is that it definitely feels faster through 4th gear so i think the power is there. Temperature definitely has a lot to do with the difference. Almost 40F delta is alot interms of IATs and making power.

Exactly.

While 36* is substantial you are still talking about IATs in the 60s which for a turbo motor is conducive to good results.

I PM'd Mike a while back about these turbos and his selling point to me was that his customers love them. I am a technical person and I apologize if I don't want to spend money based off of people who "feel" they make good power when I see this forum is full of people who don't even understand how tuning works.

These dyno results showed what I feared. I hope not as 1900$ is a good price but for 1900$ I expect to be able to flow enough air to flirt with 500rwhp. I would say that any turbo upgrade here should efficiently be able to hit that as the stockers can get to the low to lower mid 400s. At redline I would like tq to not drop off tremendously and HP to still be climbing. If I am going to replace the turbos I want it to be worth it.

Can we see EGT data, can we see flow numbers, can we see 1/4 miles on the dyno so I can see how it plots, can we see logs of any and all parameters...I offered to help with this and pay (I have had real sponsored vehicles from large national/international companies in the past) to help out but Mike felt that customers saying they like it was enough. My offer was to help with all this including the use of tech like 5 gas analyzers and more to show any and all info that intelligent customers would want to see.

If I hadn't used up the disposal income I am willing to spend on mods on previous cars that I made big power with I would attempt to have a friend of mine who has a few huge BMW records make twin mani's for me to run twin 28r or 25r but I just don't feel like going the custom route anymore. Being the first is fun but tiring.

I want to give Mike a chance. I know someone who feels he deserves it as they did a great job on his 700awhp evox and my buddy is not one to let others do the work in the same light that I don't let others touch my car.

I am pulling for you Mike. Show me data though - I don't want someone's opinion that it feels better when these people don't know the first thing about cars (not saying everyone so if that was your review don't get all butt hurt please)...

anyways - heres to hopin...

I understand what you are saying, but as Clap said the stock turbos have no problem spinning to redline at 15psi, which may mean that they are still in their efficiency range at that point. Since the procede was also set to 15psi on these (exact same maps and settings, no autotune) then i'm guessing 15psi is not a gd boost level to compare these to the stock turbos. Since It was 64F IATs would probably be somewhere near 70F or more. At 26F that the stockers were tested, the IATs would be significantly less (more oxygen) and the car would also cool at a much faster rate which makes this test somewhat unfair. With this much difference in ambient temps I was actually surprised that they made more power at such at that boost level but i chose to stay at 15psi because i thought that was a safe level for me on pump gas. I'll do logs later today if the weather clears up, at 16psi. I'm happy with the performance increase that i perceived because i stayed with my buddies turbo 350z until 4th gear which i was never able to do on the stockers. Actually i was one car length ahead of him until we got into 4th. He makes 542whp on the same dyno, usually he pulled me in 3rd gear so we both felt the turbos were doing a gd job.

I realize your dyno sheet did not show great gains at 15psi.. I never tested them there.. However you are the 2nd person to compare real world results racing the same car after the turbo install..

The other was Creaminz who raced his brothers c63 over and over and over and could not pull him.. He swapped turbos and now says he pulls his brothers car like nothing.. These turbos move some air at 18-20psi vs stock for sure.. Every setup is different so I'm interested to see more dyno results along with real world results.. as long as your happy with them i am content with the results as well.. There is always an efficiency range for turbos and MAYBE the stockers are still ok at 15psi but i know 100% for fact they are dead at 20psi..

You guys need to up the boost.

Yeah i will turn it up... i'm still happy that they made more horsepower than the stock one with a 38F delta and the same boost level, that the stock turbos are known to handle easily. Turn it up a few more psi and i'm sure the gap will widen.

[creaminz]

Why dynoing at 15psi with upgraded turbos? Whole point of getting upgraded turbos are so we can run higher boost and wont choke like stockers, no? Im sorry Mike, my car is still in the Shop. I heard EAS is installing dyno in thier shop soon. I will dyno this thing as soon as i can. All i wanted was car doesnt die at higher rpm range, i was never after the higher horsepower numbers. And real life comparison showed me these turbos are far superior than stockers.

Dyno'd at 15 just as a comparison with the stock turbos to show that even at the same boost level they can out perform the stock turbos. On the stock turbos i misfired at over 16psi the only time i've ever ran them that high on just pump gas so i turned them down to 15 and never had any issues. Once the new meth kit from shiv is released i will get that and do more testing at higher boost levels. I can do a race gas dyno maybe next week at a higher psi if you guys would like.
