whipple 4.0

[Namor]

Any more tips on 4ltr set up very much appreciated (eg will standard fuel pump suffice?).

How many have been installed so far? has anyone done any serious testing/mileage with it? is it to early to say whether the set up is now fully sorted? how long did it take for 3.4ltr set up to be perfected?

I really want to buy a 4.0ltr but cautious that set up is still work in progress.

I think there are solutions for all of the problems that have been encountered so far.

A custom tune is a must IMHO. This needs to be done by someone who knows the Ford software well and also looks at all of the variables. That will tell you the status of the fuel system. The 4.0L with a 19/20lbs pulley is teetering on the edge of the stock fuel supply system. It is likely beyond the stock air supply systems capability. What I mean is, you improve the stock air supply system I suspect you would see considerable HP gains.

The folks who have purchased the 4.0L Whipple are not the type to wait for these improvement so you can expect to see many different solutions.

It just depends on what you want to do with your car.

As an update to this thread. I believe I have solved my problems with boost loss at high RPM shifts. It was most likely the bypass valve device needing more tension in the closed position. I am sure that Whipple was having problems reproducing the problem as they instinctively load the spring on the bypass valve.

The intake could be freed up to find more power but I think that is true regardless of the 4.0L, 3.4L or stock blower. If you are on the fence about the Whipple because of previous issues, just write the check and enjoy the ride. You will not regret it. (unless you want to race a twin turbo)

I know Autograf (Autograph??) in Texas had a custom air intake on their Ford GT but I sent them an email about it months ago but got no response.
