Tuned by scotty at mainstream
all stock internal b18c1
stock gsr IM-butterflies disabled
drag gen 3 turbo kit-7psi
2.5 inch dp
walbro 255
ford racing sat. 440's (bosch green top)
invidia exhaust (2.3")
p28-crome pro

 

not bad
should of gotten a mbc and turn it up to 10psi

 

Well i had one and when i was getting it tuned, turning the boost controller **** any way didnt give higher boost so i just took it out. Gonna get a greddy BC soon

 

Butterflies disabled? so are they stuck open or shut?

also thats nice numbers with only 2.5" downpipe and 2" exhaust and do you have the E or B turbo?

 

Def. good numbers with the stock int. manny and tiny exhaust

 

not bad for 7 psi.. why dont u go ten?

Obviously they are open otherwise it would rob power...

 

Why is it that people think IABs rob power at any rpm? They actually help make a bit of low-end power. Its like all of HT has been brainwashed into thinking that higher flow ALWAYS equates to higher power. In the case of the p28, they should be open/removed, obviously.

Anyways, decent power from 7psi. About on par with my bro's last teg, drag kit/fmu at 7psi.

 

Bump for my friend! Well, having working butterflies in a forced induction setup wouldnt really help anything.At least we dont think so, i might be wrong but they are good for NA. But he's plannin on getting a single stage manifold anyways sometime soon.

 

using the p28 alone keeps them open right?

 

Well theres no vac. line hooked to it so i guess the pressure would keep them open. Or closed, i dunno..

Yes no vac source will put the butterflies in their default position which is open. I originaly thought you meant the entire system was removed. By disabling the butterfly valves, your losing midrange and gaining no top end. Removing the butterflies is what gains top end power because your eliminating 4 little throttle plates from the path of each runner.

 

It says you have a crushed bent exhaust too? Good numbers for the exhaust.

I have a very similar setup, and im hoping for numbers around there.

It's very simple to add IAB control to a p28, which im going to do. I'll post up numbers when it gets dyno'ed.

 

Ehh it isnt really crushbent, Maybe he just wanted to make the numbers sound better But its an Invidia SS exhaust, mandrel bent

 

nicely done by reddohcvtec and gsrdriver on the install too, i mite add.

so vac line on actualor = vaccum (butterflies closed all the time)
and vac line off actualor = no vaccum (butterflies open all the time)

is that right?

lol thanks


Yeap i belive that is right. With no vac line attached, default for the butterflies is open.

 

Scotty does some good work, the #'s show. He tuned my H22-T just 2 days before you, but it was damn near 100*s on the dyno.

 

Yea i will deffinately be using scotty for all my tuning needs it was 95degrees when i got my NA tuned.
