how much hp/tq would stage 2 heads and a good streetable cam add to a 6.0L whipple at 10lbs boost? at 8lbs boost and no inline fuel pump i made 372rwhp. now i fixed the fuel prob and went up to 11ish lbs boost. still not happy.

heads are a controversial subject in the boosted world. the answer i typicaly get is something like the same hp at few less psi or 40-50hp at the same boost keeping in mind you will have to pully up to keep the same boost level.

i question the value of heads on a whipple set up. i think you could get to the same hp with more alky and a smaller pully. you all ready have the kit, i would spray the hell out of it(alky) with lots of tuning and a little smaller pully.

edit.. heads or more cubes will do very little for you if your compresor is maxed out. going from a 6.0 up to a 6.7 gave me 0 more peek hp but it did give me a pile of more tq down low. i am prety sure puting heads on there would have not added any peek hp either. my compresor was just maxed out.

Very nice Crash Dummy,

I was looking at the pics you have linked and I noticed the nitrous bottle in the bed of your truck. Was Nitrous used for the 540HP. Also do you have any more pics of your truck? That thing is bad ***

P.S. Sorry for hijacking the thread.

That is not a picture of his truck....That is another guy at the track.

PS sorry for the highjack again.

Crash Dummy

Sorry not my truck it belongs to a friend of a friend and ya it is pretty bad ***, he ran a high 10 the first run out and the track banned the truck so it became a show truck for the rest of the weekend. I guess I will name the pic ( not my truck) I just thought you forum members would like to see it, It just might give ideas. I will look for pics of the 2" headers I know I have some, I just need to find them I think they are on my work computer.

FWIW, alot of fantastic things are going on this year! Big Turbos making tons of power, direct port N2O systems kicking ***, Kenne Bell MAY finally get Intercooled, and, once and for all around here, I believe we'll see the myth that an Auto LS Truck with a Radix is only good for a tick over 500rwhp put to bed

Crash Dummy

MYTH!

tell me about it......

if you do this simply, and take the 700fwhp from above, subtract whatever driveline loss you see fit, you'll see much more than the previosly stated "just a tick over 500rwhp".


then you have to decide if driveline loss is static or dynamic

Crash Dummy

Oh believe me I will be more than happy to explain some of my madness to you on the 17th. Everything good takes a little work! 550-600 rwhp is about all your gonna get out of this unit at this time due to airflow but options are TOP SECRET!.
