2000 Trans Am Dyno THIS IS A TRANS AM THAT WAS DYNOED
IS THIS PRETTY GOOD??
IT IS A 5.7L--WORN OUT ENGINE,THE GUY WANTED TO RUN IT UNTIL IT BLEW UP.
IT HAS A VORTECH ON IT-- MAKING 8-9PSI [HAS AFTERCOOLER]
STAGE II JD'S CYLINDER HEADS
JD'S CUSTOM 220 CAM FOR SUPERCHARGER
STOCK INTAKE W/EGR
STOCK EXHAUST MANIFOLDS
STOCK CATYLITIC CONVERTORS
38LB INJECTORS--WHICH NEED TO BE CHANGED IN ORDER TO FINISH TUNING.
WITH NEW INJECTORS AND FINAL TUNE SHOULD BE 550+RWHP
JUST TRYING TO GET SOME INFO--I WILL POST THE FINAL DYNO SHEETS WITH A/F NEXT WEK WHEN COMPLETELY FINISHED.
THANKS
JOE D.
I AM TRYING TO POST THE DYNO SHEETS WHICH ARE IN .DOC FILES AND IT SAYS THEY ARE TOO LARGE--ANYONE KNOW HOW TO DO THAT??

I 'VE MADE THE NECESSARY CHECKS FOR THAT.
THANKS FOR YOUR INPUT THOUGH.
650 HORSE POWER AT THE ENGINE WITH A 20% LOSS WOULD BE APPROX.520-530 RWHP WHICH I AM AT.
BSFC OF 0.6 -- DUTY CYCLE OF 90% --- FUEL PRESSURE AT 60 PSI WOT
WOULD BE AN INJECTOR SIZE OF 46+ FOR AN 8 CYL SUPERCHARGED ENGINE.

JD our cars are funny. Most that tune FI cars without a mustang dyno's loading usually try to tune on the street first with a actual load and then tweak a/f on the dyno. I have seen cars dyno well on the dyno with the a/f dead on and blow a head gasket on the street. I know you know what you are doing when it comes to cars, but just in case you have not researched our finicky FI car setups I just wanted to share what others have learned tuning the FI LS1.
Can you please refrain from the "CAPS LOCK". It makes me not want to read anything you post. I understand that some are not good with computers but please let up on the "CAPS LOCK".
Thank you
Thank you

i guess it really depends on what you get used to.a dyno is only a tool--some people just get used to different tools.
i have tuned many s/c cars,fi cars,and carbureted cars.
thanks for your input--i appreciate it.
at least you are trying to say something pertaining to the thread and technical.
thanks again

I'm awaiting the results too as this is what this thread was made to show. I didn't realize you were asking for our advice on how to tune the car for more power hence I didn't feel it was a "tech" inquiring post. That's why I posted no "tech" advice. I was just asking for no "CAPS LOCK" in the interim.
When I read it I get the impression of the highschool bully yelling at everyone trying to get attention. Your results of the power so far are great and would still be well received without the CAPS LOCK. I know you're excited, as are we, so all I ask is a cutback of the CAPS LOCK. Your results speak for themselves and don't really need an entire post of CAPS LOCK.
If you are at 90 percent duty cycle then you do need bigger injectors for sure. One of the first FI cars MMS did 2 years ago dyno'd 597rwhp with 42lb injectors and stock shortblock. MMS has since duplicated that with several C5's. The weird part is back then no one believed the #'s. Actually 2 years ago one of MMS cars dyno'd 450rwhp NA, but no one believed it. Now that 450rwhp is common on a NA car it is FACT. JD your numbers are great. I expect with bigger injectors and tuning you will see close to 600rwhp. Please keep us posted.

Might as well give the customer what he asked for

Yep, 90% duty cycle is approaching the dire limits. Too risky however the owner said he wanted to run it till' it blew up

supercharged cars do require more fuel than n/a cars-you can see that.
take it easy
