Dyno Results
 

I'VE RESENTLY DYNO MY ENGINES, WE WERE LOOKING TO GET 1000HP, WE GOT 978HP AT 6200RPM 5# OF BOOST TIMING AT 32 GAS 110. HOW WOULD THESE COMPARE TO MERCURY, STERRLINGS OR KEITHICKET ENGINES 1000HP? DOES ANYONE HAVE DYNO RESULTS

THANKS RON

We need engine specs. On only 5 lbs of boost. I do not see why you could not top the 1000 mark with a little more boost.

632 CUBIC INCH, 8-71 BLOWER TWIN 1000CFM CARBS, NO INTERCOOLER, WE WANT RUN THE ENGINES AT A LOW RPM AND 5 TO 6# OF BOOST FOR LONGEVITY

HOW MUCH BOOST DO THEY RUN?

Motor should last forever at that boost. Any reason you did not install an intercooler? Intercooler may give you the extra 22HP to make 1000 & it will help to keep motor from detonating.

Merc 800SC's run 8 lbs of boost with a 420/671 blower.

My 10.5:1 632" made 900HP (@6700) tunnel ram (2X775 race demons) on 93 Octane. At 6200 power was around 870. My motor likes 32 degrees as well.

Cam is 280/288 @.050 with .730 lift on 115 C/L.

With 5# of boost you should easily be getting 1000HP, what heads and cam are you running.

Wow!!!

Ron, what`s your estimate on top speed?

Weren`t you running 118 with the 850`s?

Looking forward to see it on the lake soon :D :eek: :D

Kurt

Need a bigger Blower its trying to suck the guts out at 5lbs the heat would be lower also :D :D

Kurt, we only reached 104mph with 820hp were hoping to reach 118-120mph

the heads are 350 MAGNUM AFR , COMP CAM 715 LIFT DURATION AT .050 FOR INTAKE IS 264 EXHAUST 264 GROSS LIFT 215, THE REASON FOR NO INTERCOOLER WAS HEIGHT AND THE 8-71 BLOWER WE HAD NEW FROM OUR LAST ENGINES, TRING TO KEEP THE COST DOWN, WE WILL PUT 10-71 BLOWER SOMETIME THIS YEAR OR NEXT.
YES, WE NEED A BIGGER BLOWER
