Saw an red F150 last night in Long Beach, it had black tribal flames on the side and a No2 sticker on it. I was in my ricer so I pull up next to him and ask him what he has done. Said it had a paxton blower, he revved the engine and it had a nice whine. Said he also had No2 and was getting the intercooler next week.

Is it anybody on this board?

I asked him if he had a chip tune or dyno and he said no.

What do you think, do the regular F150 have the the same lower end. Is this guy playing with fire without a tune?

Well anyway I see him around town and told him we are going to race next time I see him in my L. Will let you all know.

 

there's a guy around here that has a "boss" f-150 with a novi on it, and he says he can break'em loose at 40mph. he said he didn't have a dyno tune, didn't ask him if he purchased a chip to remap the fuel curve, but if he doesn't, it won't last to long.

its not going to have the lower end like the roots style, but once he gets moving around 50mph, if your not far enough out in front of him, he's liable to suck you up. thats the only thing i don't like about our blowers, they just get you goin, then the truck just falls on its face.
good luck
later

"thats the only thing i don't like about our blowers, they just get you goin, then the truck just falls on its face."

Not with a Kenne Bell!

 

With the dinky tires our F150 brothers have I think spinning the tires at 40 mph is no great feat.

The KB runs out of steam at 13K rpms. That is where the warranty goes so that is how fast I turn it. The Novi 2000 is capable of 1700 cfm.

 

As Easter and others are about to show, run a centrifugal at 25 PSIG and then come talk to me about the roots lower end.

Yes, a roots does have a flatter boost curve. But when you overlay the centrifugal curve, remember to shift it up to represent the massive boost levels that they can provide.

Centrifugal boost comes on gradually, which is just what you need in a traction-limited application like a truck. And after the truck is out of first gear, boost at 1,500 rpms is irrelevant.

 

when vortech aquired paxton, more vortech kits started getting chips because paxton was farther along with there chip program so i would think the paxton came with a chip. i got an autologic chip from vortech and it worked perfect the first time.

 

Exactly. My truck is driven mostly on the freeway. I can't get traction as it is with street tires down low. With the PI 2600 stall torque converter I'm around 3000rpms by the time I start to move. Also at WOT my truck shifts around 5500 rpm then drops to around 3500 when it goes into 2nd and third and OD. Besides most street races I'm involved in happen on the freeway at a roll anyway. That doesn't even take into account the lower discharge temps and less HP required to drive the centrifugals or that most centrifugals have a 3 yr warranty and you can spin them 50K rpm+.

 

Why not a nice ball bearing turbo? They take no horespower to drive and you can spin them to 160,000 rpm.

 

Those cost more than a couple of thousand dollars.
