yeah it id those great cast pistons you have to worry about. Good job GM

 

Well Greg a little bird told me you needed some more help with your truck so i decided to return....So everyone....Daddy is back...Let the fun begin....Anyone know how to install Electric Fans?

 

I guess for now Ill stick with the 150 till I upgrade the fuel system. Eventualy I want to install my turbo and I will need an upgraded fuel system for that anyway. Where can I get wideband O2s and will my computer read them the same? Thanks for the fuel system advice parish.

 

Well Greg to make a long storie short ...it was a wet shot....Now Red2gay has it.....

 

PHUCKIN HYDE, HAHAHAHAHAHAHA


OH YEAH gonna be some MASS DESTRUCTION running that ghetto dry kit at 225hp HAHAHAHA. Better leave it at 100hp if you want to make it until your next oil change. These cast piston terds won't hold 150hp wet shot for long. Got one apart in my buddy's garage right now. Blew one piston into chunks and the pieces of it went from cylinder to cylinder. And it was setup a little fat even. 14.90 motor to 13.51@103 on the gas was the gain. Lasted about 6 bottles.

GOOD LUCK BRO.

 

i see people put a number on what these motors can take before they let go because that is when theirs let go. WERE YOU WATCHING AND LOGING FOR DETONATION? if you werent then your numbers dont mean much. you can blow up a motor with a 75 shot i bet if you let it detonate.

i still say based on my experience with a stock 6.0(cast pistons) and 250+hp worth of power adders that a stock 5.3/6.0 can take 200+hp worth of nitrous if properly set up, tuned, good gas.... unless there is some weekness in the 5.3 pistons that the 6.0 doesn't have.

i am making my deductions based on my one experience so maybe i had the fluke motor but i really think it is all about not leting it detonate(ever).

 

I agree with Parish....My ******* put down over 170 extra hp when sprayed...at the wheels which means it had to be making around 220 plus at the crank extra. Again I was just being stupid and having fun....Spraying mine from an idle on tires....I sprayed 2-10lb bottles and 1-15 every Friday and Saturday night for over three months through mine....Just the high cylinder pressure killed mine....lol...So I only have one thing to say,...Spray On

 

Went to the duct tape bakini contest Sunday and ran with the 86 NOS jet and emptied the bottle. My 1/8 times were 8.8s, 8.9s, and some 9.0s. It was over 100 degrees outside at noon when they had us running. Anyway, long story short the truck took it like a champ! I had to wait till I was up to @ 20mph to spray and even then the tires spun most of the rest of the track. It feels a little crazy going down the track and the back end being loose at 50-60mph. One weird thing too is my engine always made this slight piston slap noise since I had the heads done, but since Ive been spraying it runns smoother and quieter.
