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.
The block in the pics of my car is Nick's block. I got it from him, and he designed my bottom end.

a double pumper ID2000s with Fuel Rail/FPR and dual feed line have proven to work up to 900hp. And you wont hear the fuel pump when youre on the streets!

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

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?

I looked around and see what your were talking about as far as cars using the double pumper. When I started buying parts for this project, double pumpers were not making that kind of power. Maybe nobody pushed them enough? I bought the eliminator fuel pump and never really thought about it again. Thanks for the input. Jeff

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.

JB, does your system have a constant fuel pump whine? For me, that's a deal breaker on my DD. The Walbro is whiney enough

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.

Yeah but the 3.5" exhaust drowns it out above idle

It becomes unnoticeable on the highway even with the silencer in for road trips though.

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!

I'm pretty sure they are 156mm rods. The pistons are flat top 10:1 pistons. We used a factory evo water pump. No nothing special to the block other than tap it. Thanks for the interest, Jeff.

Any updates? Excited to see how this project is coming along!!!
