While we are talking fuel pumps, I have had great realiability with the fuellab 41402 in our engine dyno test cell at my day job. That thing has been run for as much as 100 hours straight at a time for the last 14 months and had not given me any trouble...We do use the speed control function as well with a constant pressure of 40psi.
Also those are sick numbers for a mustang dyno, congrats OP get some fuel and see what she's got left

 

Have you considered modding the fuel pump housing to be able to run dual Walbro 400's? I believe JMS is running this setup on a few of their 900+ whp cars, not sure on how much headroom they have on those setups though.

 

Its already done

The fuel system now has two Walbro 400s, going into -6 lines, to a Y-fitting, into a -8 line to the front of the car and a -6 return line.

We ought to have enough fuel now!

 

nice time for 800+whp lol i would be scared to drive that thing. have you drove it during the summer months while being hard blocked ?

 

Drove it most of last summer and it was just fine. Never had any overheating problems whatsoever.

 

Amazing Numbers

 

Hi from a fellow MI Evo owner. When are you going back on the dyno? I just had my car on SI's dyno last weekend, your car must be ridiculously loud in there haha

 

I'm not sure it will be going back on that dyno again...

 

Some awesome number!!

 

Put it on a Dynojet for giggles.

 

Thanks!

Yep. Its stupid loud in there

Thanks!

That would be fun. Would be over 1k I'm sure.

 

Crazy! You have any track times?
