First OFFICIAL TWINCHARGED M20 BUILD

[Denny]

all I can hear in my head are cut gears, 80's music, and twin charged cars

Yeah and how about the music from my inspiration car (0-100mph in 2.5 Seconds)...lol... I have the exact same Twincharged system (not components of course..).

:D Oh I know!... I didnt take it any other way! :D LOL...Im pretty excited too!

Dude, I only joke. I am just so waffling excited to see this.

I'm checking out the GOPRO "white" camera for 200$ cant go wrong!

I know a lot of people have been very patient on the videos nothing I want more then to drive this car....its pure torture to have it sit in my garage and that I know I could be having serious fun right now!! But I also need a passenger to video...not easy to find all my friends 35-40 year old lol... busy with kids...wives... and damn life in general!! I will find a way to get some videos to really show you all the brutality of this car


I ordered the valve today as soon as I get it I am welding and adjust it for 17PSI. The beauty is I can always raise the boost if I want more....looks like I got plenty LOL... and no more worries of overboosting

You come in here with 11 posts and tell me I'm doing a hack job! Buddy YOU have no ideal what you are talking about ok read my thread and understand what my setup is.

Unless you show me your twincharged setup or understand the concept which you dont...I got no leason to learn from you.

12! (Now). Seriously though: I did not want to offend you, i just wanted to help. I do not own a twincharged car, but i DO understand the concept of twincharging with its multiplying pressure ratios very well. Well, maybe someone with a high enough post count to be heard will chime in...

[Denny]

GoPro is you passenger. Get one ;)

Cant fracking wait for video

Too funny thats Exactly what I'm surfing online for right now LOL... Plus I want footage when I go drag racing and I dont want extra weight of another passenger with me I am already 230 pounds lol...!!

I dont want to be an ass, but thats a bandaid/hackjob. No need to bleed off boost, just get your turbo boost control right...

In for vids.

no video?

Makes sense, since there is a slight pressure drop through the intercooler and piping. So?

wastegate will usually open 2-3psi later if plumbed to the manifold instead of the compressor housing in my experience.

I'm trying to understand :( first I will explain the signals on my setup.

• Turbo wastegate spring 8psi and signal comes from turbo compressor.
• MSII computer is getting signal from intake manifold left nipple
• Boost gauge and fuel pressure regulator from intake manifold right nipple
• BOV(before throttle body) signal from SC intake (after throttle body)

Everything is getting proper signal and works very well. Problem(not really a problem) is the multiplication of boost on a twincharged setup. Which 10 PSI from SC + 8 PSI on turbo = 23 PSI and all that boost hit hard and extremely fast :)

The size pulley I would need to bring down my boost would rub on my upper rad hose and I dont feel like having a new Crank pulley built again.

thats why the BLV looks like a good option as it would safe guard my engine and bleed boost at high rpm so I can keep the amazing low end torque I have now.

No need to install a bigger pulley, in a twincharged setup you want as much boost from your primary (the SC in your case) as possible, for the fat powerband you mentioned.
What happens if you plumb your wastegate line to the intake manifold is that the turbo always adds as much boost as you need to reach your pressure goal. In a nutshell: You dont tell your your turbo "always boost the SC inlet to 8psi", but instead "always add enough boost to make it (for example) 15psi in the intake manifold"
If you have a 15psi spring or a mbc, plz try it. No need for that strange 200$ bleed valve...
