No problem, someone has to be the guinea pig right? Right now, only 14 degrees. That will change soon.

If the tuneup was "full tilt"......maybe then I would be pissed. With that said, I'm pleased with the car...and that's really all that matters. Even though the car is slow by ls1 techs standards, it's still fun to drive....to me. I understand that your car is far superior to my junk, but I really couldn't care less about any of that. Just want a grocery getter that's fun....to me. See the theme here guy?

the404man

yeah thats what im talking about, i couldn't care less who is faster than the next, all's i want is fun, tire spinning fun ha man sweet

this makes me want to turbo my truck that much sooner.. sigh lol man lol

was wondering what rpm did you see around 12psi of boost and by what rpm did you see full boost ?

im wanting to go twins but money wise, it will take me longer, being iv got a 2500HD 4x4 i need that down low, its a work truck... ha but i so want turbo NOW lol so a single sounds good i pull a trailer though mostly junk and wood... maybe i should just wait for twin 61s or 67s or 70s or something..

neways again sweet sweet ride man.. thumbs up and peace

Game ova

Good question, to be honest...I didn't pay attention to where full boost hit. Was focused mainly on seeing if I was maintaining boost, and was seeing how the oil pressure was doing. But i see you are in Tyler, does the name cody bloodworth, mark Bewley ring a bell?

the404man

Seems like iv heard of a bloodworth before, did he run the old round D round dirt track out in rusk years back ?

And ah that's ok, i think i should wait for twins anyways as bad as i want to just get the 78/76 and be done with it.. but yeah thanks for all the data you put out on this On3 turbo all the trash talking about them almost discouraged me from even going with On3... for the money i really dont think you can bet them..

Game ova

Nah, cody has one of the fastest cars in the southern region, no dirt track. Not sure how much power you are trying to make, but twins for most.....really isn't necessary. Just more stuff to buy, and more things to break.

the404man

ahh yeah prob dont know him then sorry man .. But do you know if he has a youtube.. id like to have a look see at his car .. i searched his name but only came back with kids

And as for as power number nothing much really just maybe 2 to 300 extra out of a 01 5.3 or 04 6.0 just enough i can be running 50, 60mph and break the tires loose .. i love drifting .. BIG TIME

Game ova

Then I would recommend going with the 6.0, because it takes lots of torque to do 60+ mph rolling burnouts. It is fun, but very frustrating when you want to feel maximum pull...but you can't because it just spins.

Is the billet wheel a different design than the cast wheel or just a copy?

Game ova

After seeing the difference between the two, I'm beginning to wonder if billet is all its cracked up to be. I really think that if this on3 had just a higher flowing housing, it would have matched the precision in horsepower. On the street, It seems like the on3 actually spools faster even though it has a cast wheel. And no, I'm not just saying that to bash precision.

What does your car dyno and what does it ET/trap to back it up? What turbo do you have? Assume you easily make over 1000whp on 20lbs for this to be disappointing to the point of being pissed. Also, I would hardly call 14 degrees of timing and 20lbs full kill, sounds baby soft to me.

Also define a lot? I think the scaling and different rev range skews it a bit but once looking at the chart in detail it doesn't appear much if any further off then the 50-55 claimed difference.

Excellent comparison between the two turbos. I think all but the most hard core would agree that the little chinese turbo that could can deliver a ton of power for most peoples goals. This also gives me hope for the T7875 I just installed that replaced my TC78.

Game ova

You are right, and you will be able to make plenty of power with this turbo. But, there's always those, like that Drewsteen guy out there that no matter what will knock it because it's Chinese. Yes, you will take a lite hit in power, but 43rwhp is a very small price to pay....and can easily overcome that hit assuming your tune isn't already at the ragged edge. And I say 43 hp....because since I missed the boost dial in by .5psi the car likely would have made 775 at 21psi which is where the precision was.

Do both turbos have the same size turbine wheel and exhaust housing?

The difference in power could easily be different days different weather.

Game ova

The turbine wheel is 1mm bigger.....still .96 ar. I did think about the weather, but it was hot both days I tested....so it would be hard to say that the weather hurt me yesterday.

necrocannibal

Well the true test is going to be trap speed. If they are the same or with in a mph of each other then you will know for sure.

I like the fact that the power differences happen several hundred rpm earlier on the On3.....interesting. Might just be a different tune away from making the same or more power and torque.....oh, and that half pound of boost. LOL

The weather correction factor (WCF) numbers shows similar for both runs so I agree it was certainly warm both days.
