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 FAX# 207-797-8950 |
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 |
