Here is the final result of this car. This is where the tune will stay. Maybe if I decide to be generous i might give him a free C16 tune. If I do i will update with the numbers.

This car went to the track tonight and ran a 11.6 @ 130.90

Could not hook at all.

what was the 60ft?

You were running out of fuel on a wally 400 at under 600whp? Sounds like something else in his fuel system is holding him back, shouldn't run out that low to require a double pumper yet. The wally 450 on my car put down 775whp on e85 no less.

But regardless, glad you have it all tuned up, looks like a very potent pump gas car.

Had you bypassed the stock filter in the hanger and used an external filter? I was considering using a 450 with a Boost A Pump in stock housing but didn't want to run into a flow issue with the stock filter assembly.

I did a lot more than just slap it in there, so its not apples to apples.

I had the Wally 450 (e85 version for reference), I ran a new AN fuel feed line (-6AN, not too much bigger than stock), Adjustable fuel pressure regulator, boomba fuel rail, fuel lab fuel filter (the big *** one), fic 2150's and modified the return in the pump housing.

So yea, its a "bit" different. But i am on e85, so the extra pump room i have there should be neglected since hes on pump gas. I guess I am just saying he probably had other fuel constraints besides his pump that were holding the setup back and he was simply able to overcome those by getting A LOT of fuel pump in there.

He may be approaching the limit of the factory filter. Like I said I was going to use the stock hanger but thought I would run out of flow no matter what pumps capacity was before the filter.

It went all but 131 in 1/4. So ya it goes decent for a 94oct car. This is over 1500ft elevation.

I know some cars work good with the 450 and some not. The main key is to get a boost a pump or use a really good wire from battery to pump so it runs a lot of voltage. the pump will flow like crazy with lots of voltage. Then upgrade the feed line, and get an adjustable FPR, and it really flows. Most guys that run this pump don't have everything setup right and instead of making them jump through hoops, i just recommend the double pumper since its more convenient and guaranteed to work great with the car. But when a 450 setup is done right, they can flow quite a bit of fuel.

I believe my issue was the stock fuel lines... I could not get the base fuel pressure under something like 53psi with the walbro 400. Since I planned on switching to E85 in the future I figured the double pumper wouldn't hurt!

I believe the 11.6 run had a 1.83 60ft. I will have to look at the slips again.
