I have successfully shot 175 dozens of times on stock bottom, single nozzle wet. I have also shot 180 dozens times with NXL, even with its large, long lean spike from launch. I even shot the 220 NXL Shot a couple times, but had straight C16 and only 12* timing, so I ran quicker with the 180shot mix C16 and 22*. You can shoot the LSx platform a lot, but you gotta have the tune for it. Yes everything has its limits, but I am sure much of the stated limits are way underrated.
GL with it.

Shiat, I sprayed 175 shot with 28* timing, 5.3L heads (higher compression) and 92 octane









Oh yeah, I melted my drivers side plugs, head and block between 5 and 7 cylinder, DON'T DO THAT

But, I still ran 11.1 @ 117

I'd like a little clarification on this. Are you saying that a 400-450 rwhp heads/cam/bolt-on LS1 can NOT handle a TnT 150 shot? I ask this because my car is being built this summer with ETP 215 heads, UD pulley, LS6 intake, moderate custom cam (228/232 114 or something close) and a TnT 150 wet kit. I would think the sponsor that is setting up my car (New Era Performance) would have warned me against this if in fact it was true. But all Mike said was that to run a 150 wetshot safely I want a traditional split on the cam, new fuel pump and a good dyno-tune (all ready have the plugs).

400 + 150 = 550 x 15% = 82.5 + 550 = 632 hp @ the flywheel...if it's a weekend warrior with occasional N2O use it will hold it... my statement was to the fact that a stock motor will easily handle a 150rwhp shot, a highly modified motor will handle it but at a cost of longevity and you're on borrowed time

i'm runnin h/c/bolt ons + 150 shot now with no problems but i cant expect it to last forever

I am running a 423hp h/c motor and spraying a 150 to the wheels dry shot.I have run 10 plus bottles thru it and it still runs fine.I dont know how much longer it will last but if I was that worried about it I wouldnt have sprayed it at all.once you start modding and beating on them they will break.might as well enjoy it till it does and not sweat it.

You technically couldn't expect a stock car to last forever. All motors die eventually. But what I was getting at is that if you run all the N20 safety equipment, have a good nitrous cam, have a good nitrous tune and don't spray every time you drive the car then shouldn't it hold up ok? If my motor is going to blow up after 1-2 years then that's 10K down the drain (so to speak). But if the motor lasts 3+ years (looking for more like 5+ to be honest) then the money was well spent (and time for a stroker ).

I know the transmission will fail and probably my 10 bolt as well. I am prepared for that. But I'm not prepared for a blown motor right out of the gate.

Sorry for all the posts but would a 100 shot be noticeably safer for a 400-430 rwhp H/C car?

please don't go there.. your comment is entirely off base.. i'm making right around 440 on motor.. and putting a 200 shot to it on PUMP gas with 25* of timing and a good rich tune.. been doing it for around 15k miles now.. bore scope shows perfect cylinders.. last compression check was perfect as well as leakdown..

the LSx based motor can take alot.. but its all in your tune.. if your scared to make 550 on juice you need a new tuner.. PERIOD

And what kind of times are you running?


I find that hard to believe, 25* of timing, pump gas, and you car didn't blow something up

What plugs are you running TR-6's or colder?

Ok guys, before anyone gets too ballsy....

blacktransam....a couple questions: What AFR are you saying is good and rich? And what kind of cam?

I ask that because you may have a cam that bleeds off more cylinder pressure than our post originator, or orange ss which will allow you to run 200 shot without spitting head gaskets or whatnot. Lower cylinder pressure longer life, fact. Also, afr, if your running it say 10.0:1, and then run a 150 shot at 11.5:1 I bet you'd be quicker, again, more cylinder pressure. Just my thoughts so far on this particular arguement.
I dont need a warning either, so try not to go to your nack

Andrew, you surely did split some internals.

H/C car here at 42k was spraying 150 and burnt the #7 piston and walls at the time dynoed 432 on the motor.Had sprayed 100-150 since 1200 miles. when H/C package was done second run blew it apart. Currently 225 dual wet/ dry kit with built 6.0 iron block no problems

I think how much these motors can take is relative to what you put into it. If you have a direct port system and jet the lean cylinders a little richer and use a good progressive controller and miltiple stages you could spray quite a bit on a stock short block. Also like mentioned above a cam that bleeds of cylinder pressure is going to help alot too. However all this stuff is going to be exspensive.

the cams a 242/242 595/595.. it runs an 11.1:1 on juice with TR7 irridium plugs.. OEM headgaskets AND bolts

i in no way think i am a legend.. i just can;t stand when someone with no PERSONAL experience gives an opinion on someones set up.. BURN'EM has been there done it..
I am on my 3rd motor experimenting with my nitrous dreams of 700+ reliably on a stock bottom end.. I have EGT bungs in every cylindar.. have spent countless hours on the dyno.. and some one who is scared cause of stories he has heard.

Hell NEXT on this board ran a 175 shot on a heads cam motor for a long time in the 9's on a stock bottom end..

all i'm saying to the starter of this thread.. look at the people who have PERSONAL experience in what you are trying to do.. everyone has opinion and on the internet everyone is a ******* tuning god.. thats why theres the go back and look at others peoples posts function

I tried ruuning the TR7 irridium, but they kept fouling out

Do you just street race, do it for the dyno #'s, or doing you have any 1/4 mile track times.

Sounds like you have a good setup

black....thanks for sharing. And I agree, there are lots of it going on, thats why I like to ask ppl to be more specific sometimes. Appreciate it.

the car has gone 11.002 with a 2.3 60' with a 132+ mph trap speed.. we'll just leave it at that..

orange i am very sorry i came across as a dick..its just here on the internet everyone has a 10second car and is a ******* tuning god..and i had just got out of an argument in another forum where some guy was trying to tell me that aftermarket heads are a waste of mony on these cars cause you can;t make heads flow better then factory and i was a little pissed off..
