Its only tephra v7 that has an option for 100% WGDC below a definable load.

 

ya im basing my experiences on tephra v7.

 

its not just me. its a lot of customers as well who have experienced the same as me. i am not here to make cars heavier or sell stuff that doesn't work. that is not me and never will be.

I don't know what else to say. if you want to continue thinking what you're thinking in the regards of the way they perform that is perfectly fine. im only trying to help. <-- i realize you can say the same for me.

I got really angry/upset though when i read what you posted that i highlighted in bold. I felt that was a very rude comment.

Its ok though. i made it clear that im very confident in what i said, and if need be have a ton of cars that can back my claims up. Im not going to have my customers flood this thread though just to prove a point.

At the end of the day you have experienced a different result on two cars, that i have not on probably 80 atleast off the top of my head on hybrid boost alone.

I've converted cars over to mbc that were on 3 ports alone that had serious boost creep, after adding the mbc the creep went away. why? because there was not enough boost being built soon enough downlow to avoid the creep. that alone should be enough proof to show that the mbc can do things the 3 port is not capable of on our ecu.

 

sure. Don't expect it to spool like an EF2 or anything...it's not that much different. But it will be noticeable. I was originally on the 3-port like you and made the switch based on Tom's recommendation. He wouldn't BS you. He prolly has more experience on the hybrid setup than anyone.

FYI the Forge UNOS according to boosted tuning's test is the best spooling, and holds boost the best out of all the ones he tested if you decide to go that route.

 

I still have my hallman mbc I'd probably use that one

 

also think about an external dump 02 as in the larger wheel'd turbos tend to yield significantly better spool.

 

tempting lol

 

I am installing the MAP o2 eliminator with recirculating o2 dump... think I'll still see good gains/better spool than my current downpipe/o2 housing setup?

 

I just installed the same... tune saturday Ill let you know

 

spool over the titek? maybe. More power compared to the titek+stock downpipe? yes definitely. I think map's 02 eliminator downpipes are the best setups out there at the moment, but the dump is going to be better, especially for spool. The stock turbine housings even with TD06/TD06H turbines machined in them are actually quite restrictive and the more airflow you try to stuff through them from larger stock framed turbos the more of a difference in spool and power an 02 dump is going to make as it doesn't disrupt the helix and releases back pressure off the turbine wheel. Ever wonder why 02 dump set-ups cause boost creep? ;-) The stock internal wastegate passageways are not really large enough to control turbine speed when it's free flowing(and the turbine aero has a huge part to play in this variable as well, but we won't go into that). You just don't ever creep on a recirculating setup because the added back pressure on the turbine wheel actually is like a bandaid and allows the internal wastegate to keep up. FYI It's an even bigger problem on the anemic 28MM flapper on the 7cm dsm housings.

 

so 02 dump = better spool?

 

in alot of cases yes. The FP black guys are reporting 200-400 RPM better spool just by going 02 dump. Look it up.

In my honest opinion I think the way forward for your goals is 4" intake+SD, 02 dump, and a hybrid setup, and if you happen to make more power along the way with the better spool and response then I don't think you will complain. my thoughts.

 

im definitely leaning toward a 02 dump and hybrid setup. The SD setup will probably wait til a built motor comes along

 

I have a 3" downpipe right now, getting rid of it and the Titek though.

And thanks for the lesson, will file it away in my 'boost knowledge' mental library.

 

OH BTW... thought I'd post this up. Guess what I got yesterday?
