Car rolls out damn hard for a crappy LT1 
diagnose my backfire
diagnose my backfire start off with car specks
cam only ? dont know the cam
ss3600 stall
22* timing
114 in the stand alone running the nitrous
nitro dave custom dual stage
ok went to tha track tonite havent been in a few weeks...finally got some new tires and wanted to see if i could make the car hook...its been a while ive been having problem hooking the 125 shot...
i made 2 good clean passes without issues on the 125 shot...the second one pop'd on the launch, but didnt affect the car at all? it was out the exhaust, i thought maybe too much fuel?
then i tried to bring in the second (75) kit about 20 feet out and it spun the tires...we were like huh? so we decited to hit both at the same time to hit the tires harder and set my window switch at 3600
hooked then poped and the car died? made sure nothing was wrong then restarted the car drove it it had no issues?
went back made a good motor pass no issues so we were goana try to hit it with it all again and stall it higher, and change the window to 3800...stalled it to 2500 instead of 2000 and went for it...it backfired and i think cracked the intake...but it also shot fire out the exhaust...heres a vid...why do yall think it did it?

what details? the first pop didnt affect the car at all...and it came out the exhaust i thought it was just a freak thing
made a clean pass after that without issues
then the next pass i thought the nitrous was just comming on too low or maybe my bottle was slightly low and it puddled..

Do you have a wideband on it? Is the fuel solenoid working? Did you verify the standalone pump is working? Is the window switch working correctly? To me it sounds like its going leeeaaann on the initial hit.
window works....
stand alone works...BUT i just saw it last night it had a little leak in the ribbed line...im goana have to call hsw tomaro...but still that pump should support 650hp it had a small leak...should have been able to take the 200 hit
no wideband but i have dynoed it and af was actualy great then got lean but the bottles were overdilled and pressure dropped 150psi
fuel noid is working because the car hauled *** all night

anyone else got any ideas?
i was thinking too much timing or fuel puddeling?
on a side note i notice the car gets hot during runs...sits and idles at 185 all day but end of a run it is about 210...i dont know if thats from pushing water or just hot from running...cant believe it gets that hot in 6 seconds...
any way to check that? its got stock heads with stock bolts and stock gaskets i think

Like mentioned above, pull the plgs and see what they look like. You may want to post a pic and have some members read them if you don't know how. If you've still got an LT1 in the car, why would you think you cracked the intake? Do you have an LS1? Usually only the plactic ones break?
ya ls1.....plugs i didnt look at before i started the car...i was dumb...nitro dave at first thought lean pop but my stand alone seems to be fine now he thinks i might have too much timing....
but i just remembered the way harris setup their tank the pump drawls from the front bottom of the tank...maybe the launch pushes the gas to the back of the tank and caused lean pop??????? anyone ahd something similar happen?

Fuel pressure safety switch hooked up? It shouldnt be getting hot after a single run. That tends to indicate its running a little lean. Do you know how to read spark plugs?
