Hi Comp Twin Turbo Build So Thats what i'm trying to do.
370ci 6.0 LS with twin PT6766s CEA Turbos 11:1 compression No intercooler With Dual Fuel using 16 Injectors (Pump gas + Methanol) Controlled by Holley Dominator EFI.
The Idea is to have very Efficient Motor off boost with the small primaries and very powerful Motor taking advantage of the Methanol on the secondary injectors without the need for the intercooler even with the hi comp that will help spooling the turbos at low RPM.
I'm thinking of ramping the methanol injectors on when gas injector reach 80%DC and will try to size them to reach there at about 105 KPa. this way i should have the least amount of gas with boost just to be safe and i should be able to run a lot of boost with a lot of timing.
the reason i thought about that is i already have most of the stuff to make it happen.
11:1 370ci 6.0L LS short block with callies Rods and wiseco Pistons.
225 ETP Heads.
Moran 235 LB/HR Injectors.
Holley Dominator EFI.
built 4l80e Trans.
And access to cheap Methanol.
My goals are 1000rwhp street/strip beast.
What do you think guys?
What should I pay attention to?

I like the idea. But why not do an intercooler. It could only help and be more safe. You could probably do a fmic using a really good core for less than a grand.
That is a similar set up to what I am running, but E98 instead of methanol. 11:1 408, 16 inj with 87oct/E98 stock PCM. I am switching at about .5-1lb of boost. With E70 I was seeing some KR around 185* IATs with a BR7EF plug, on E98 the KR is gone. IATs end in the 220-230 range for me at 16lbs. On the previous 5.3l I was seeing 19-20lbs and 260-265* IATs w/ br7ef plugs. I started out using 30lb red top injectors, and 83lb injectors currently as this is my first dual fuel set up. I have a set of FIC2000cc on the way and will also be trying a -10 spark plug to help combat the high IATs. I may try methanol later this year.

we should compare notes man.
I like you setup, would you tell me more about it? how much power your making? any head lifting?
