instead of the kick in the *** feeling, it will be a smooth pull but feel quicker at higher rpm.

 

Ah ok

 

Very nice numbers! Where in MI do you live? I'm in Madison Heights, also with a white evo8.

 

I am in Pinckney about 45 mins north of a2

 

That sounds awesome... I may have you retune me next year what's a map ef4 turbo compared to an FP? Like an FP red?

Also, I know this has been discussed before, but is it completely possible to use like a grimmspeed 3 port to control the boost curve, then use like a hallman in cabin to control PEAK boost... that way you still have the ability to turn up the boost but still have the convenience of having the hallman at your fingertips

 

The EF4 is larger then a FP black.

 

So it would be safer to use a bigger turbo because youd have a higher powerband... than to use like an fp green which would produce more low range torque. That way you can take advantage of the higher powerband (5-8K right?) just wondering if its okay to rev to 8K with the stock bottom end. Even if you have cams+valve springs

I ask this because I see your graph only goes to around 7K. With that large of a turbo you'd want to be using the higher RPM range right?

Just being curious... I like to learn and be knowledgeable rather than to just guess and spread incorrect information.

 

R u sure that's a single walbro255? On e85 they run out of fuel way before that?

 

I would hope two, I ran out of fuel with my Green on a 2.0 and 2150's on E85 with one modded 255.

 

I only rev to 7k because I can't really do 130 mph on a 2 lane road that has woods and animals around me everywhere I look. I don't really have access of a road with nothin I don't live in the city at all. Thats why I am only at 7k.

 

Positive this car had the fuel pump in it way before they came out witht he double pumper for the evo. They had them for the dsm, but not at the point for the evo. Guy I got the car off of had it modded with only 3k miles on it and he auto x and road raced it. That and I have recepts for everything on the car.

 

Curt your car needs it hahaha. When I bought my car it only had 325whp mustang dyno on it. In the future the car will get a double pumper just have to get enough cash and stay working long enough to get it done.

 

530-540 is where its normally out of fuel on e85 with a single walbro + enough injector to compensate.. Brians car is running near 13 AFR's though, so the IDC is not entirely maxed out. we definitely need to get a double pumper in it though .. im pretty sure the pumps punched.

next mod = br double pumper or walbro 400.. personally id take the br double pumper anyday over any other fuel pump. been working like a clock on my car ever since i installed it.

 

Well you knew my b day was last sat do I see a late present hahaha?

 

Nice thread, my friend.
