How much boost??

[KNOT-RIGHT]

Ok all you supercharged guys post your hot setups.
Static compression?
Boost pressure?
Displacement?
Heads?
Cam?
Intercooled?
Type of supercharger?
Engine Hours?
Trying to see how many actually run over 8lbs of boost? on 8 to 1 motors. Pump gas.
Thanks in advance.

[Craig]

* 9.3 to 1 compression
* 7 pounds boost
* 509
* GM iron sq port
* Crane hydraulic roller
* Superchiller
* B&M 420
* 50 hours
* 878 hp @ 6000 rpm
I do run av-gas because of the higher compression and I run 34 degrees advance

Is this your setup that you are running on pump gas, with no cooler. Thats some pretty good power if so.. KELLY

yup i pump whatever 91 octane gas i find at the dock or gas station. I forgot to mention that i do have a Superchiller on it though.
:)

nice info herehttp://www.kuhlsuperchargers.com/tech%20p05.htm

Nothing better then being able to buy gas anywhere :D :D Without my blower on right now I have 7.3-1 comp so it has been kinda nice to run 87 all the time.. I was thinking that you were not going to last long on 91 and 7 psi without a chiller, good numbers.. :cool: :cool:

[Fiat48]

Can I play?
12.5 static
509 Ci
Brodix BB4
Roller custom grind (all day, all night duration)
No intercooler needed
Littlefield 8/71
34 degrees locked Mallory Super Mag III
Dry sump oiling system
Enderle Injection
Boost 17 to 24 lbs depending on the pulley
Hours? 7 to 8 seconds at a time.
Octane? I dunno. I don't worry about it tho.
Fuel mileage? About 1/2 of what you get. But worth it. :D

[Dimarco21]

Fiat 48 is this motor in your family boat?..........:D

[Fiat48]

Yes. To me the boat is family. LOL. :D

i will tell you when it quits breaking parts and runns for a little longer!
vp c 12 fuel i dont know the motor octane off hand

Whipple intercooler
quad rotor whipple EFI
13lbs boost
timing at 29 degrees max
pump gas when not racing or on a poker run
will change to 16-17lbs real soon and run good gas, not sure if straight 110 or a mix. Depends on the egts.
runs 1350 egt on pump gas and
1200 egt mixed with race gas
30hrs so far

[don johnson]

I am running 2 Teague 1050 HP motors. Specs;
JE 8.5 to 1
11 lbs of boost
4.5 x 4.5 Merlin - 572 Cubic Inches
LA Enterprise Kryptonite Cranks and Carillo Rods
Brodex BB2-X Heads fully CNC ported
Crane Hydraulic Roller. Top secret Cam Grind so I do not know the spec's
Superchiller
Mooneyham 10-71 Blower
Running 32 Degress, advance locked out.
Twin 1150 3 circuit Dominators
85 Hours without a single problem. Rebuild at 250 Hours
I run pump gas and run this boat hard in the poker runs and at Havasu in the heat. These motors don't burn a drop of oil, in fact I have trouble building enough oil temperature. The oil temps never exceed 140 degress even after running at 6,000 RPM for over 20 minutes. Water temp runs 120 degrees. This is one of the reasons I can get away with pump gas at 11lbs of boost.

Some nice setups here.
Lets see some more. :cool:
