what hp are the flux 4.3s capable of with the right programming and air from twins on fuel only?

 

lmills did 8-- or so

 

Tim B. did a little over 900 rwhp with those on his '06.

 

4.3's are big injectors in the '06-'07 trucks.....For some reason they rattle pretty hard when installed in the can bus trucks....Something to do with rail pressure and the pilot event....

Tim Barber is working on a solution and I have a few ideas of my own, but unless you are fearless I wouldn't go there in a daily driver (right now).

The Flux 3.3's are supposed to run flawlessly and will easily produce over 800hp with a decent fuel setup and twins. There is probably 50hp between the 2 sizes.

Flux 2.5's are capable of at least 750hp in a well setup '06-'07. Flux 2.5's run smoother and quieter than stock in my truck yet they produce enough power to seriously test all but the best aftermarket transmissions.....Trust me on that one!

 

I did 875 with my 06 on 4.3, On 3.3s we did 824 uncorrected. The 3.3 is a much better injector for 06-07 street trucks. All my 900+ runs have been on the 04 with flux 6+. The 555 motors run better on really big injectors. Tim

 

Tim B did 875 with his 4.3's on his 06.
Lloyd Mills did 866 give or take with his 4.3's I believe
Rip Rook has some 4's ( the first ones I ever made actually ) and his truck ran a 10.91 in the 1/4 mile on Diesel Only last year.

So, roughly 850-875 is probabaly a fair number.

What is your combination? Looks like you did 855 already? What type/kind of dyno was that on? Was that the 4.3's?

 

863 on 4.3's

 

Don,
im running your 4.3s with a smarty 4.2 and mp8. 62/65/14 on top and s400 on bottom

 

Just an s400 and you got 855HP? Thats real good IMO.

Everyone I know has a S480 to make 850HP and up. They all have a larger top ( secondary ) turbo as well.

 

i use the truck to tow so thats the reason for the smaller setup. i thought about going with a bigger set but hate to lose the spool-up. i think with the new tnt/r i can improve on that number a little

any chance you can post up the dyno sheet on your 855.1 rwhp #2 run ?

64/65/14 - S400 855.1 on #2 ..... that's really good with that setup

 

I will try and help out with the dyno graph.

I thought with me having the 480 turbo on the bottom I would be able to put down some better numbers but i have yet to do so on fuel .

 

the top turbo is a 62/65/14

anyone know what kinda hp gains the tnt/r has over the 4.2?

 

my mistake ......... 855.1 with a 62/65/14 S400 ........

on #2 WOW sounds like a world record you got there congrats !

looks like you hit those #s on a mustang dyno


do you have any 1/4 mile time slips ?

be cool to see how fast 855.1 moves your truck down the track !

855.1 is amazing for a 5.9 cr 62/65/14 S400 set ( on just #2 )

 

it was a dynojet 248
