Besides a lot of money obviously. I heard there's a guy with a mid 9 second 3rd Gen that has a 406 in it that runs partial pump gas. I'm wandering what kind of engine setup and how much boost you would need to make that kind of power and still be able to run pump gas.

 

One of my friends (Dean Lambson aka The Hog) has an 85 camaro with a 406 + 180 shot of N2O that ran a 9.97@137.6
It had V6 front springs and drag shocks in the rear, plus a 8 pt. cage( the cage is now in MY car :-) ), sub frame con. ,12 bolt w/ 4.11's (i think, maybe 4.56). The motor was built with mostly used circle track parts. However, now it is back halved, 12 pt cage, tublar K member, and most important more N2O (250 shot I think). He should have a timeslip in the next few weeks.

 

it takes big bucks for one


for 2 it will take alot of boost
let me elaborate.

suppose u start off with a 350 zz4 motor.u would have have to boost it a mininum of 19 pounds of boost.now thats alot of boost like race gas required boost.i dont think a zz4 motor would survive...so u would have to really put in strong parts forged everything,orings.or u could up the displacement(remember no replacement for displacment). so take a 400 sbc rev it to 6000 rpm u would only need a mininum of 9 pounds.now i say mininum because as u know superchargers takes hp to run it ,so u more than likely need more boost.

 

the way i see it cubes vs volumetric efficiency gives you a rough torque estimate, so from there you look at RPM to give you a rough horsepower estimate.

a 400 SBC at like 85% VE N/A can make about 470 Ft Lbs of torque at that peak VE i would suppose.

now shove 14.7 PSI of boost through it, and you double that number, minus the power required to drive the charger, and minus the air density lost from heat. a good intercooled setup can provide a very close to ambient temp, so figure around 16 PSI to actually doulbe a motors output.

thats nearly 850 Ft. Lbs of torque at that VE. spin the motor up a little past 5400 RPMS and your making over 850 horses, over 650 at the wheels. thats pretty far up there.

now just imagine a stout 427 cranking 25+ PSI. can we say 1800 horsepower? its that easy.

 

You don't need a lot of boost to make 800 HP?

Winston Cup cars do it easily lol.

For 800 hp, I'd say your looking at spending 20,000+ lol.

I know for our race cars 467 Big Block, it was $30k and it dyno'd 750+ hp from Kevin Enders.

 

saw an article in this months hot rod about a 454 small block crate motor (Bill Mitchell?), Im betting a decent bit of boost on that baby would get you where you are wanting to go.

 

You can build one for around 11k or so. Cheaper if you could get the setup to work with a carb.

Aftermarkter 400 block.
Eagle rods/crank
Wiseco or JE pistons dished
AFR 210s
Solid roller cam
8.5:1 compression
your choice of intake (just match it)
followed by a F1 or D1R

Local guy put down 700 to the rear with problems on this setup. Those are all off the shelf parts, with no modifications.

Th guy your speaking of is Tory Hess with a 9.27 or so run. He ran a very close setup as this one was above, except ran 9:1 compression and ran race gas mixed with pump gas.
