Compound turbo build and other updates

Hmm. .7 Undivided gated housing. Interesting.

Theres a S300 housing like that as well from BW

 

[12vCumminsFTW]

Welll I'm going to try it. It looks very similar to the he351 exhaust housing.

I think it'll definitely spool slower mostly because of that undivided housing, but hopefully not as bad as the .88 LOL

Yea, I hope its not too bad. I can definitely see it spooling slower than a divided .7 housing. But it should flow better right? The ports on my old divided .7 t3 housing were pretty small. I can't see it being that much worse than the 351 cause I already have a t4 manifold with huge ports going to a undivided t4-t3 adapter. And it spools fine how it is now. But what do I know, I'm not a turbo engineerLOL

Hmmm got me interested, following along.

Just took the die grinder to a brand new turbo lol. Gasket matched the flange and hogged out the gate port quite a bit.

LOL im in negotioations with the wife right now on getting one as well.

Skip that pansy turbo cliff hahah

 

[ahale2772]

i cant wait to see someone use a 62/68/.84 as a secondary, that little billet wheel can handle some air.

Well it appears that with the way the turbo is clocked with my straight manifold the waste gate actuator is right smack in the way of the oil drain. So I'll have to relocate the bracket or build a spring gate I guess. Ic pipe might need to be modifyed too. Crap.

Why not just make another oil drain?

I would except the actuator is right below the oil drain outlet on the turbo.

Ah. That does present a problem.

 

[12vCumminsFTW]

Ok so finally got the turbo on, had to modify the wastegate actuator mount but everything else fit pretty good.

It spools a lot slower than the 351, but still better than the 66LOL. 20 psi or so at about 1750 rpm locked in OD. I'm pretty sure the gate is opening way to soon though and killing the secondary. At 40 psi total primary was at 20 and egt get toasty fast.

 

[12vCumminsFTW]

Blocked the gate line, big difference! Spools a bit faster, total boost around 80, 28 or so from the primary. But drive pressure went over 100 quick. egts are better, did some wot runs in OD and only hit 1500. HP might be up a bit.

I'm gonna put a boost controller or regulator or some something in the gate line and fiddle with the gate adjustment rod, hopefully I can the drive down and stuff.

Dang boots don't want to stay putLOL

First quarter of this year if everything continues to go well and we are not strapped with more taxes from the biggest group of idiots to have ever graced politics.

How long is the hot pipe.

 

[12vCumminsFTW]

How long is the hot pipe.

not sure, about the same as any other side-by-side compounds.

 

[NickTF]

Am I the only one that thinks the length of the hot pipe could possibly be a concern with primary on top twins? Could be off but it would seem the hot pipe should be kept as short as possible.
