Ok, and? You don't have to beat the hell out of the car to hit a decent trap speed with a few drag runs. He doesn't have to do anything for me anyway; it's just nice to see trap speeds to match dyno results. We see far more dynographs with big numbers than we see 1/4-mile results to match them, so it makes it hard to compare and keep tabs.

What it all boils down to is...what does it take for the rest of us to make that much power on pump gas with those mods? He's only got me beat by 75whp and 120wtq. Something tells me that a set of cams won't make up more than a 1/3 of that difference, haha. My MR is not worthy! :bow down:

 

The funniest thing about this story was as the car was being strapped to the dyno the customer, another customer (Henri from Evo-NY) and I were talking about his expectations and the customer was saying that we would be happy with 350 whp

I told him that it was highly unlikely that we would reach 350 whp as he still has the stock fmic, stock fmic pipes, had a high flow cat and was on pump gas with no alcohol.

I suggested that a mid 330's to 340 would be the ball park I would expect.

His first pull on the dyno tonight actually made more power than this one but his clutch slipped so bad that it looked like garbage.

On this pull, I kept the same tune and just lowered his boost a bit to avoid the clutch slpping.

After seeing how much power it was making and how smooth it was running it was deemed unwise to risk trashing a brand new clutch to try and sqeeze out some more power. I am sure that there was some more power left on the table.

Sometimes, its good to have to eat your own words. I was really happy that the car proved me wrong today.

After 2 1/2 years of working on evos every day, they never cease to amaze me.

 

Hey Al, so what it sounds like is that for whatever reason, his car is not knocking at high boost on pump gas. In essence, he's able to run race gas/meth-level boost while on 94oct without any knock and thus no timing pull, right? I know that when I run anything over 21psi on pump, I knock. Hell, it happened this past weekend in 60 degree weather en route to my 108.4 trap after an 87mph 1/8th. I know that if I tried running 23-24psi like when I'm on race gas, I would have knocked through the roof. You said this car was pushing more than 23psi when the clutch was slipping, so something must be allowing his car to run this extra boost w/o knock...

 

Not really, we typically can press 22 - 23 psi of boost peak - falling to 20.5 or 20 on the DYNO with pump gas and no knock

For some reason on the dyno I use at Pruven the loading charateristics require you to run about one psi more boost than on the street to closely repliocate real driving loads. After all, a dyno is just a tool which appoximates the conditions on the road.

Also, please NOTE that on race gas and alcohol I spike the boost up much HIGHER - to 26 - and even 27 psi peak

The shape of the curves on the dyno sheet speak volumes about the state of the tune. Its one of my best dyno sheets to date after I cant even count how many hundreds.

With the boost cranked all the way down and some race gas there is no doubt in my mind that this car would have easily gone over 400 whp.

 

Al, you think the power has anything to do with that UNOS MBC? Ive been looking to get one to replace my hallman just because its polished.

 

If we go all the way back to case study # 19 one of the first MR's I tuned when the 2005's 1st came out we can see what a typical MR would make with similar mods with my flash on pump gas

https://www.evolutionm.net/forums/sh...ght=case+study

Almost a year ago similar weather -also uncorrected



In some ways I have learned more ways to push the better 10.5 hot side turbo over the past year, but a lot of the gain is due to the particular car

 

GOOD point. There is no doubt that the Forge MBC with the supplied heavy spring is a MBC which holds the boost level more steady and longer than any other MBC. The Hallman is also very good, I just prefer the Forge.

 

Is this improved tuning ability with the 10.5 something you are able to duplicate on the dyno and in a street tune or just on the dyno? What about mail-in flashes? I think my 05 is more likely to match the MR from a year ago. In fact, if I could even get as high as 340whp/wtq after cams, I'd be happy, but that would be a gain of 45whp, which I'm not to confident about...

 

Interesting, I pretty much see knock anytime the boost spikes higher than 21psi and that was on 2 separate Dynojets, but it was also in the summer no lower than 80 degrees. I also taper to 18 or so by 7500. A 22-23psi spike with a taper no lower than 20 without any knock on pump gas would suit me quite well!

 

For example of what a dyno sheet with higher boost looks like, here is one going way back to case study # 4 with 100 octane fuel and higher boost peaking well over 25 psi.

You will note the area of max peak tq is much narrower and more pointed

The stock turbo is incapable of pushing 25 plus psi for very long and it qucikly falls flat as indicated in the sheet

On the dyno sheet of the MR in this thread it holds the tq much flater and smoother because the turbo is not being pushed as hard

 

Well then its time for some cams and a custom flash for you

 

Just out of curiosity, how are you logging knock ?

BTW - in the case of the dyno sheet I posted above, you can note the complete absence of knock induced ecu reactive response in the totally flat a/f curve and the smooth tq

 

I'm not logging it directly, but rather inferring through changes in timing much like your second comment. I see no indication of knock on this dynograph like you said...

 

so this guy is making 390wtq and 367whp on pump gas, no meth??? thast like 50 more tq and 30 more whp then any other car with the same mods. I've heard of factory freaks but this is just off the chart. AL, are you sure he didnt have race gas in the car?

 

Those numbers are unreal and congrats to the lucky owner. I would really love to know why this car is making so much power than others with similar mods.

Anybody else have any theories on how factory freaks are created (besides good combo of parts)?
