Default Looking to make 800WHP !!!

So, i know i can push enough air...

BUT... what do i need for fuel ??

I have my barrels twised up and pump maxed out... 700cc's

i have been thinking about 7x.014 (yes 7holes) as i've been told they're more friendly for a daily driver and smoke less...

I have the HX40 on top of the HX60, so it spools up really quick... with the correct tuning ??

5x.018 should be in order, or do i need to go bigger ???

Remember, this is a daily driven truck, and it tows....

I picked the HX40 and HX60 setup solely for the purpose of towing, but now i'm going quartermile crazy and i really want to step my game up, as i've made some promises on ET that i really hope that i can stick by

I really didn't realize that the NV4500 would hold me back so much, but i will be looking to build a RH47 for next season, and i would then just swap that in and out for running down the track, the NV4500 would be used on a daily basis, and i would peg it back to 600 horses with a fuel plate when using it on the streets

That way i should be able to stick with my SB-13125FEK a little longer

an 800hp DD that tows is out of the question. it just aint gonna happen let alone its dangerous for everyone on the road.

what are your supporting mods? headwork? camshaft deminsions? this is a VERY VERY high number to get to and even try to street it.

I think it's possible

No LAW against it here...

No headwork yet... aside from studs... thinking i should ring it, have a BIG STICK cam, only have 60# valvesprings but am looking to change to 120# possibly...

I know i have the air for 900 HOT HP, just unsure what i should run for fuel..

good luck. you have a very expensive goal in front of you. towing with injectors that size wont work. you have to be boosted up to burn the fuel and generally while towing you are no more the 10lbs. engine melt down man. cant have it all you have to choose.

pullin street strip towing reliability price ect ect. no such thing as a a truck that does them all well.

Forget him

I'm going to 1200 on a 12v and it will be on the street. I say 5x.018s with your pump. Has it been on the flow bench? Set up correctly 800hp should be easy. Hope my cam goes in your engine. Should be fun!!

Thought that was sent towards me Dave

Well beyond just selling it I have come to that it won't hold up to fast shifts makin the power I will be making. I want to drag race it and have fun with rich souls on the street when roads are closed of course.

Sounds like only way to hold the power and be able to shift fast and frequently is to go zf6

You have waaay more fuel than you need. I'm North of 750hp with my little 160hp pump pushing just over 400ccs. The 5x18s would be the best choice, but I think the HX40 is going to hold you back.

750-800hp is fun to drive on the street occasionally, but it can be a pain other times. I certainly wouldn't want to tow with it. 550-600hp makes a nice street truck
