my buddy's camaro that we just finished...644 hp @ flywheel... 541hp and 535 ft lbs torque at rear wheels! we think we can get 700hp with bigger heads and cam, but we want it to have streetable power throughout the entire rpm range. tried to post a dyno sheeet, but it won't let me,..file too big.

 

Good results. How did you get both FWHP and RWHP?

If you already have the dyno sheet in electronic form then just re-save it with less resolution. I have been taking 4Meg jpg images and re-saving them using MS photo editor at less than 100K. They look OK and upload fine. You should be able to get good quality at less than 50Kbytes. Not to mention huge files are a pain to download/view.

 

Justin-

Load your pic onto Photobucked and link it.

If you want me to do it, e-mail it to me real quick jbertellotti@yahoo.com and Ill do it.

 

thanks red, i figured out a way to do it!
it is saved at lower res below, cclick on it a couple of times to make it bigger. Anyway, the dyno gave the rwhp and rw torque, but they multiplied by like 1.2 or something and got the crank hp. power was there pretty much all the way through the rpms. 12.0:1 air/fuel all the way through also, dropped off to 12.7 all the way above 5,500rpm to 6,200. maybe need bigger injectors? they fattened the fuel curve up as much as they could during the tune.

 

ok here it is.

 

here it is on the dyno,...click on pic to make larger.

 

Not without spinning the blower faster…

 

the heads and cam are really small, not set up for peak hp. the blower was hot on the 644hp pass too. i'm sure we can get over 650 as it stands with a cool engine. but if we need more boost, the motor is only 8.5:1 compression now

 

that's the part that you're not getting... the blower is moving a set ammount of air now, increasing or decreasing the restriction behind it (making the engine flow more or less) may make the blower slightly more or less efficient, but will not significantly change the ammount of air that it is moving, but it will change the boost that you see on the guage.

if you increased the engine's airflow AND turn the blower faster you'll move more air and keep the boost level about the same and make more power, of course, you might get that same power more efficiently just by turning the blower faster and letting it make more boost, depending on where on it's compressor map you're on now.

 

cool...well, i guess it's plenty of power for now

 

how much boost were you running ? What were the turbo's ? did you fab it yourself ?

 

12 lbs intercooled ATI procharger (supercharger). 383, 8.5:1, AFR heads. 215/220 cam i think on a 116. It was a kit,..we did not fab the setup. LT4 motor (was LT1). 42lb inj. computer tune...1200cfm tb if i remember correctly and full length custom cooks headers. those numbers (644hp) is through cats. twin intercooled...numbers were also when head unit was hot.
