New build at ASAP-EVO IX-4G69 on E-85

Nick @ JE has done a 10.5:1 4G69, he is the first one to tell me about the block. I do not know if its finished or not.
I have noticed my coolant temps during a pull barely move with the 4G64 block. From the research I have done I think the 69 will be about the same. Typically I start all pulls at 172* and on a 2.0 it will end up around 188-190. My car was 172 the whole pull at 584 and only barely hit 175.6* at 679.

Hoping to hear from CWill, JB, or Mikey why they choose a non-double pumper system.

I'd be very surprised if this was the reason for not going with a double pumper fuel system. I would speculate that taking the Hobbs switch/relay out of the equation and going with one or more inline fuel pumps provides for more linear and predicable (controllable) fuel flow. With the Hobbs or even MAP switching on a double pump systems you have one pump on or two pumps on. Is it possible that the trigger/boost point switching the second pump on/off can cause issues with fuel delivery and unwanted stress to injectors and FPR?

For what it would have cost for me to do a double pumper the way I wanted to I did this and saved money. The Magnafuel is only 470, so I sold my 255 (which was fairly new), my new filter, and did this fuel system. At 708whp on E85 I am only 76% IDC on the Evoscan 100% scale. It went up 3% over the 679whp pull for reference. I am using 2150s at 43.5psi base pressure.

First off the build is such an awsome setup. It is a very thought out build. I am very happy to be apart of it and i will see that it turns out to be everything its cracked up to be.
As for the headgasket ? someone asked. Were using a 4layer stock headgasket.
As for the block not being strong like the Evo, as jeff said earlyer i dont see thsat being a problem hondas, subraus etc make more power with weaker blocks. The car should be running this week and on the dyno soon.

Thanks again Chris for all of the effort and kind words, I only hope the car can live up to ASAP'S reputation for fast cars.

This is very interesting. I have a few questions since this is a shortdeck 2.4 block. I see you list the dimensions as 87x100 so I am guessing the rod size must be the x-factor. What length rod are you using with what compression height piston? Also what water pump? Did you have to do something similar to the 4g64 blocks? A lot of questions I know, but I like where this is headed!
