Twin turbo

[GLHNSLHT2]

looks sweet, any pics of the inside of the manifold?? curious how the air gets to each turbo.

Looks great.

I suspect you will have less issues with surge than I had with my twin turbo on the 8 valve engine.

I'll get some uploaded here in a bit

I'd love to hear/see more about that project for sure!

I'm excited, apprehensive, and a little scared of my project and I would love to hear from others that have tried similar setups.

For starters, I do know that the firing order is 1-3-2-4 so because the manifold is designed the way it is to 'work' but not provide evenly pulsed exhaust flow for the turbines.... with that said, on with the pics!

Exducer bores:


O2 flange ported to match a 3" housing:


Runners (you can see in runner #2 where a 'diverter' was installed to help guide exhaust flow to the new secondary turbine):


I'd love to hear about people's thoughts and feedback!

Took a nice look at your site. Nice results for sure. Definately unique fab work for these setups

I saw boost at 15psi when you were single turbo, what did you run with twins? Any dyno results?

[DblTrbl]

The twins only went up to 24 psi. Over 24 psi, I had surging issues. Never dynoed it.

I have surging issues with TE04H's on a 2.5 16 valve at all but WOT. Don't know about max boost, and I think the TT SRT-4's didn't have surge problems with stock turbos. Did you look into the ones someone was making on SRT forums? They recast a manifold for the second turbo, ended up much like yours.

Finally have some progress

Yes, I have seen some of the work on the srtforums and I made this one because I didn't like the design of theirs.... I don't believe it was recast though as I'm pretty sure it is welded as mine is.

I haven't heard about much of any surge issues in twin form, but some in single (insty-spool) situations.

I wanna see some ASSEMBLY pics as soon as you get going with that.
I wanna see how this turns out.
Sound wicked!

That is the reason I made the kit.... I can tell by looking at that pic that DCR has never designed a collector in his life. The inclusion angle of the manifold (post exducer bore) is terrible and actually has the exhaust flow directed partially AGAINST eachother, not good for best performance.

[BobsBlackACR]

Alright kiddies, here's the next installment. Porting, cryo, and ceramics are all done now Looks uber sexy IMO.

Just time to get some plumbing squared away and get it installed

Pics:



Starting to get ancy now!

looks good, you open up the wastegate hole a bit?
