I have a 98 firebird 6.0 truck motor and 243 ported heads 585 cam flat top pistons 373 gears and longtube headers ls6 intake and lid with truck maf sensor. Ready to go 11.88 dial ins 114mph . I just put in a 150 shot of nos wet kit. with race tech fuel punp. 4 degrees out of the timing with tr-6 plug. I think it is ok but 10 bolt rearend I am afraid. 225psi cranking compression will it blow the heads off. thanks Let me know what you think

 

has the rear been beefed up in any way???
what tranny???
converter????

 

rearend is stock with 3.73 gears with auto and 2000 stall.

 

just wait till you hit 2nd and spray....

 

that is what I thought I should do so I hook up a switch on and a button switch so I can hit it for a short time and not when it is shifting. will the drive shaft make it ok I was 11.88 so with 150 shot will it go 11.25 and live.

 

Hit it....whats the worst thing can happen????? blow up??? chicken!!!!!! LOL!! J/K!

 

get AAA first then hit the button!

 

u should not have n2o if u don't want to use it?

i believe u should fix all the weak links if their is-if u are scared-

chicken-just hit it-best thing i bought- i go through 2 bottles a week-i want my moneys worth-and its well and paid off for me-

 

Maybe I will try 100 shot first. Will this car handle 550 at the wheels. I have heard the floor pan will blow up. Should I get frame connecters. I want to be ready and not explode something. Will the plastic intake hold up. I am ready to try it if you guys thing the car will hold it.

 

I've been spraying 150 running low 11's no problems. Left the line with just over a 200 shot. Pulled a 1.483 60 foot pulled around and staged again. BOOM!!!!!!!!! no more rearend



Just spray it.

 

if you break something, its a better excuse to buy something better!

 

200 shot blow out your rearend. Was the 150 shot ok for awhile. You have a lt1 with the alu intake. Or is it the plastic ls1 intake. thanks

 

I have a full weight h/c car(no **** 3450 without driver, still has everything it came with) It has went 10.4's @130 with a 150. I sprayed it as soon as the last yellow dropped and pulled a 1.48 60ft. I have a stock 10-bolt(all the way stock) with 3.23 gears and I think thats the trick. I dont trust the 3.73's. Plus if I had 3.73's and you might run into this problem as well, my car would shift into overdrive before the stipe, unless you ran a 28" tire. IMO 150 out the hole on 3.73's w/10bolt...........better bring a trailer. I know there will be a bunch of guys saying they run a 10-bolt with 3.73's and have no problem and thats great and probably true but just my opinion put some GM 3.23's in there, spray the 150 and run 10's all day and still be 20+ MPG.

 

pray and Spray!

 

225 psi cranking pressure? That is alot. What is the LSA on your cam? You need to pull at least 6 degrees out for a 150 shot. 2 degrees per 50hp is what I use. As for the 10 bolt, good luck.

 

cam is 226 at 585 lift 225 cranking compression is alot I thought. but alot of power I was 11.88 dail in full weight. may 100 shot on stock pistons is better.

 

just go 4 it man ull do some pretty nice numbers hitting of the whole, and if it breaks save some money 4 a 9 inch or a dana 60

 

The 150 shot alot last year and this year with the bigger stall and cam no problems. The yes a LT1 with alu.

 

UR CRAZY!!!

I only TRIED that much after I had a rear end and transmission. The motor liked it though.

 

uh, you are hoping to go from 11.80s to 11.20s with a 150 shot?

Try well into the 10s unless you're driving miss daisy.
