1985 GSL-SE

116 rwhp @ 6k rpm
116 rwtq @ 4-4.5k rpm

Stock intake, stock porting, FC header and pre-silencer, RB aluminum Flywheel

140k miles on the engine.

 

these are good sized numbers =) i love the sound of a rotary in the morning =P

 

Yeah I accomplished the rare feat of having more torque than horsepower in a rotary! (even if only by a few tenths)

Time to start looking at ways to improve the top end.

 

Approximately how much power @ the wheels should a 84 FB put down with the following specs?

Engine: PROFESSIONALLY STREETPORTED AND REBUILT 13B ENGINE W/ALL ATKINS SEALS INCLUDING APEX SEALS. RACING BEAT INTAKE W/HOLLEY CARB (I BELEIVE IT'S A 650CFM) RACING BEAT HEADER W/3" EXHAUST. COMPLETE MSD IGNITION SYSTEM W/2 MSD6 BOXES AND 2 BLASTER 2 COILS. HOLLEY ELECTRIC FUEL PUMP W/PRESSURE REGULATOR. ELECTRIC COOLING FANS.

Transmission/Differential: FRESHLY REBUILT 5 SPEED, 8.8 FORD GEARS IN LIMITED SLIP REAR END W/HEAVY DUTY AXLES, 6 PUCK CLUTCH.

 

1984 GSL-SE
165K on odo
Total stock
And I too managed to have higher RWTQ than RWHP

 

Directfreak, are you taking any correction factor into consideration for the Mustang vs. Dynajet dyno. The Mustang dynos put out numbers 8-10% lower.

 

doubt that he is, i don't think that this info is meant to be a battle of dyno queens

 

Well just pulled a 164.6 whp at 6900 and 132.2 tq at 6500.

 

1982 S2 RX7, 12AT Turbo, 1/2 bridgeport, stud kitted, gt4202

302rwhp @ 13psi.

Within 2 weeks, will be going E85, & 25psi

 

where have you been living? anything that sheds rotating mass is going to free up power.

 

446rwhp @ 23psi E85

 

Reducing rotating mass will allow the car to accelerate quicker... it will NOT make more horsepower.... PERIOD.

Lets make this simple analogy... If you were spinning a 50# kid around on a merry-go-round, would it be easier to get the kid "up to speed" than spinning a 400# fat *** man?? Yes it would be easier to move the 50# kid.

Does it mean you all of a sudden have more energy (power) because you are able to move the 50# kid faster??? NO... you are still the same.

 

Well I just made 393HP/315 torque @ 14 lbs of boost.
Streetported, 850/1600cc injectors, Precision Turbo, 46mm wastegate, Haltech E6K.
Engine was built @ Streetpower Peformance and tuned by Steve Kan on a Dyno Dynamics Dyno.

 

Mine:

 

all right boys
583 rwhp at 18 psi
399.6 rwtq
pump gas
76mm turbo

 

I will be updating this Shortly - Any last minute info - Post it now.

 

cool, thank direct ! one thing though can we keep old numbers with old configurations up on the board and just add a new set for a new configuration ?

thanks again

 

This is a SP 12a engine, Fuji Racing ITB, Megasquirt, SDJ headers, Custom exhaust with "expansion chamber" all tig welded, Racing beat light flywheel.

The only other number I'd like to see in there is my old holley carb one which is already on the list ....

 

I'd love to see what the torque curve looks like for that setup.

 

here's that graph

12aT 338 whp 1/2 bridge , fuel injected 1979 rx7

 

Let off at 6800rpms in 4th gear. Not totally tuned, ran out of time on the dyno. Money.

 

675? God Damn Chuck. What a Monster!

 

here is the dyno sheet
