Compound turbo build and other updates

[12vCumminsFTW]

Nope I haven't messed with the fueling. I'm gonna tear into this weekend and hopefully figure something out. This thing sucks.

WG v-band langes still leaking like crazy. Probably the whole problem, dammit

see if you can find a small piece of flexpipe like used on ford/gm up pipes. I'd add a flex portion after the wastegate so the vband flanges have a bit of wiggle room to seat when they tighten up.

Yeah thats what I was thinking of doing. Just need to find time to tear it all apart again.

Well I machined some block off plates for the gate ports and it spooling a bit better. 20 psi at 1750 rpm now. This housing must flow good, drive pressure is not too bad even with no gate LOL
Still takes a while to brake boost but thats mostly cause the TC is too tight I think. so with some tuning it might be ok. I miss how fast the he351 spooled LOL

Bigger is always better, fast spool is over-rated..........


Hopefully you can get this new monstrous setup dialed-in, then I will have to eat my words...

oke:

Hey now, I like fast spool, and the he351 does just that. But as I and others have found the turbine side becomes a choke point. I'm trying to build an efficient setup and keep drive pressure in check and not peg my 2000* pyro everytime I floor it:badidea:

Don't floor it.

Guess PEAK boots can't take 80+ psi for long?

Made a nice popLOL Turbos seem ok. Need better boots.

 

[Ghostman]

Ouch.

Get straight boots if you want them to last

 

[DDually]

Straight as in no bends? Straight as in no change in diameter? Or straight as in both of the above?

 

[Lostnwalmart]

No bends

 

[mathews8pt]

That's hard to do at the intercooler

 

[ahale2772]

weld a 45* 4 inch bend on the end of the intercooler, wahlah straight boots

 

[Extended Power]

Who needs blow off valves when you can just use your boots...

Seriously...you didn't hear that "pop"?

Err wut? Just mimic the bots ben with a pipe and wala straight boot possible

I'd hate to weld to the IC, I was thinking maybe add a 3" bend to the IC pipes and use a straight reducer boot to hook up to the IC. Kinda like Spearco does it.

LOL

 

[TURBOLVR]

at what pressure are the boots blowing? what IATs?

That one blew at 80 psi, no idea on the IAT's
