[QUOTE=06black;3476377]then this Steve you speak of is an idiot.
He is talking about Psychostevo, or "Steve", is a well respected member of this community and has tuned many LNF cars, but not many with big turbos though because there are not many to speak of yet.

Today I went to Dejon Powerhouse and finshed my turbo swap! All I can say is WOW!
Though the tune is still under developement the car really feels strong! Here ar some specs on the turbo and related parts.
Percision 5457rb (its percision new "50 trim" replacement)
500hp rated
T31 series with better spool and less back pressure = more HP!
"54 refers to the compressor inducer
dia. and 57 to the turbine wheel inducer dia. It uses their latest billet
turbine wheel which is more aerodynamic for faster spoolup. R is for ball
bearing center-section and B is the compressor cover."
Full Kit Info will be aval. soon. Pics Monday!

Oh, it is hard to red people's emotions online. It just sounded to me like you had some kind of issue with him when you said it all makes sense now I guess to ment that you realize who Boostking is talking about. BTW you are knowledgable in this area why dont you suggest something to him that he may have overlooked becasue if the intake cam advance did not work I know of no other ways to get a faster spool.

not to mention advancing cam timing should work ... ... theres NO reason he should have that much lag... tuning can definitely take care of that
there are people that have bigger turbos ... with a better spool

I dunno. Unless he has too much intake cam advance that would cause the intake valves to open too soon before all the exhaust gas has escaped that would cause some issues. I think he just needs to find the correct balance of intake cam advance, A/F, and ignition timing for his setup so that it will build compression sooner. That will take some trial and error because as far as I know he is the only LNF with this setup.

any person for that matter, who thinks they have the knowledge to comment on the tune of this motor all while saying that cam timeing (phase) will have little to know effect on boost response is part of the growing group of people whom need to stop talking. educate ones self.
cam phase dictates air flow across the head, manipulate this to achieve max cylinder fill while running a late spark event along with the ext valves open will jump egt's witch will in turn add to boost response in a vary quick manor.
as for suggestions, its not my job to fix your set up. i engineered mine for a good long while, and its delivered amazing results.
i suggest you do the same. educate ones self for best results. relaying on other people will get you mixed reviews and an uncertain future.
your hotside is NOT the issue. that's a tiny guy.
I'D START PLAYING WITH THE BASICS!
one or the other at first. cam or spark. spark is harder to **** up thus start there.
bump mid range to get the cylinder pressure up to make more off boost power then start playing around with big lumps eaither positive or negative at the transition point.
work it out from there, then go to cam.
yes, the higher the gear, the more engine load, the QUICKER the turbo will spool.
all other things being equal.

I understand what cam phasing does. I am simply saying I am seeing no results up to this point. I changed the cam timing in 1 degree changes. and didn't see any results. Trust me I have spent hundereds of dollars on dyno time trying to teach myself..... once I find that bal. I will be SHARING MY RESULTS!!!!! I am not here to keep anything from anyone. thats what a forum should be.
If you wish not to help then stop posting... your not helping any! I know how to tune and what does what. I am stating that cam phasing up to this point has not worked. thats why I am asking for any recom. I have paid my dues now I am looking for some ideas!
I will def. be pushing 7000-7500rpm. I think the meth will give me what I need for the fueling on the top end.
I didn't before because I was have some plug issues. that is now fixed.
more dyno testing coming soon!

any who, why would you mess with the intake cam first? or much at all?
the exhaust cam defines the fluid flow that determines how the turbo reacts.

it not how much, but what direction, and at what ratio.
not my job to solve your poorly engineered system's flaws.
yet again, another point of direction for you.
slapping a different turbo on to a OE turbo car does not count as paying your dues, once again, average, and neither does averige results.
keep working, your a head of all those sheep whom only talk about turbo swaps.

playing with the cam phase can either increase, or decrease spool, and when set right it will increase power. hell a simple -3/-3 on it will pick up a smidge of power and decrease spool times.
there is also another apparent problem of running out of injector timing.
notice something between all the larger turbo lnf cars. they all seem to be around the same power levels, same boost. this right here. this is the answer to big numbers.

Not really
so u dont have a dp or exhaust right? So then after you get the dp and exhaust, after that you could be at 400whp 400wtq ..... what would be needed to see higher numbers after that? Also is this gonna benefit from the gm stage kit? Or should I get all the stuff and just tune it? I have alot of money saved and am SOOOOOO confused what I should buy

I've seen several others with LNF try it and it's not worth the $400 to gain 5 whp..... Just like Hahn makes a claim of 15-17 whp for their cool ram, that's power a person should definately feel and yet several cool ram owners say it just sounds better, more cool but no real power increase... This is why the CAI experts (K&N) have not made a CAI for this car..... just like below 330 whp it's pointless to upgraded your exhaust on these cars......

the more negative on the intake the more advanced it is right?
the more positive on the exhaust the more retarded right?
Thanks for posting Dave!
