Ok. Got and elbow from Aaron at 6061. This thing looks great and it was at my door in just a few days. I opted for the seperating plate. Pics below. What are you high powered guys doing to seal up the TB and elbow at 20+psi. I was thinking about machining for an oring but if a flat gasket will work ill run with it.
Let me know what you think.


Hey guys,

I am looking at a twin setup this time and am curious what you guys think. I am looking at the cheap stuff right now out of curiosity. First of all this car is 90% track duty if not 100. Instant spool is not important. I just dont want a 6 plus second spool time at the light. Th400 with about a 4000 stall, 232/240 595/608 115lsa cam. I am going to swap this cam out most likely for something that matches whatever setup i end up with. This will definitely be e85 or racefuel only, no pumpgas here. Lol Goals are 1k-1250hp, mid 8 or quicker if possible.

Cx GT3582 t4, i think though they would spool well but they will not support that much power on this displacement.

So that means I'm probably looking at 70-78mm. The 78/75 my brother uses as single is a very nice turbo for the price. How do you guys think spool would be with something like that?

On a seperate note. I have the chance to pick up a PT101/106 cheap. I have no experience with a turbo of this size. If you have experience with a turbo this size and an engine around my displacement please share your experience.

Thanks for all the help guys.

9:1 compression.

Just stick a pair of BW 366's if you're on a tight budget.

And current cam would work fine.

No budget really. What would you recommend in place of 366 if budget isnt important?

I may have a pair of precision 6766's for sale brand new still in original packaging.

stevieturbo

I'd live to try a pair of the new Precision 6870's...but they're well outside my budget.

So the closest alternative for me would be a pair of the new 6973 SXE's or something close, although dont think you'd need to go that big for your goals.

eg a pair of these 66mm's would easily get you there and still on a sensible budget

look at Turbonetics T60 series turbos. They are in the $650 range and can be made into a million different sizes.

Those 6973 are sweet but overkill if I am raising the cost to where there are a lot of options. The 366s are a decent price for sure. What housing would you go with? 88t4?

stevieturbo

I cant really see any reason to use a housing other than the open 0.88

LJMSJohn

S366 with a 73.. turbine and the .88 or .91 housing.... for 699 each... Or if you were wanting a little growing room... there is the 69mm S300SXE for 999 each.

Is the $699 without turbine housing?

LJMSJohn

699 is a S366 with turbine housing.... its not an SXE model... its the old style compressor housing.

Thanks guys. Got two S366 73mm turbine .91AR from Jose at Forced Inductions.

Im also going back and forth on A2A or A2W intercooler. Im currently thinking A2W and maybe meth incase i want to turn it down and run pump fuel. Anyone have any opinions on this?

I am also going back and forth btn truck manifolds and fabbed tubular manifolds. Let me know what you think.

What can you make on pump gas on twin 6766s

nossty1

iTrader: (3)

I guess that mostly depends on bore size and heat. I personally won't push past 900 on pump just because I don't have a reason to do so. Aa big engine could easily go further.

387 lsx. I plan on pushing it to the max
