Opinions on 150 shot on stock bottom end
I just want some educated opinions on running a TNT F1 150 shot on a stock bottom ended car already making 400rwhp.
1.Are the stock hyperutictic pistons a problem with 550+ rwhp?
2.I've been told that if I ran a 150 shot at the level I'm at now, my motor is
on borrowed time. True?
3.What degree spark are you running with a 150 shot? Race gas?
I'd like to keep my motor running for a long time. So just give me what you guys run, or what you've seen or heard. Thanks.

I plan on spraying 200 on a stock bottom with 90k. actually probably 150 half the time, 200 the other. people say it wont work blah blah, its all in the tune, and if it breaks i wont be suprised. but I feel pretty safe about doing it.

I have run 200 shot on stock bottomend. See signature for times. This year only 116 octance, 28 degrees. Best 10.17 on 150 shot before I broke it doing the wheel stand in my signature. You next trip down the track could be its last. You shouldn't race unless you are willing to pay.

A lot of it is directly related to the tune. But if that thing dead hooks ~600rwhp you will probably want to start thinking about a new rear end, driveshaft, or tranny parts, haha

Well, I don't plan to hook at the track like most people. This is just for street use on 315 drag radials.
I mainly wanted to know how the bottom end of the engine would take it. When everyone says it's in the tune, give me some details. Like what timing your running when on race gas and 150shot. Stuff like that.
Also, by saying it's all in the tune, it sound like everyone is say that the bottom end of the motor can take over 600 rwhp...it's just in the tune... ....I know the factory wasn't thinking about the LS1 making over 600 rwhp and being able to handle it.

race gas isnt needed...most of us run a timing tuner which pulls the timing when nitrous is activated so you can run a good n/a tune and have the timing tuner pull the timing under a nitrous run. timing tuner pulls, i may be wrong, 2 degrees per 50shot??? (someone correct me if im wrong). thats running 94 octane fuel.
hope this helps.

Good insight Josh. I hardly drive the car but pretty much to race and for car shows. So it doesn't see too many miles. I've got the racetronix systeim and tr6 plugs. Right now I'm running a 100 shot with about 26* WOT spark. I only want to spray a 150 shot rarely, mainly for certain races, and stick with 100 shot the rest of the time. I was think around 24* timing and race gas would keep me safe.

Are you talking about the timing tuners and control boxs that run around 290 bucks? I went to a couple of sponsers and that's what I found. Didn't see Ramchargers though. Looks like a good product, pricey, but good. It also looks like a plug and play, no splicing.

We are all pretty much on borrowed time in some way or another. I've less than 400rwhp cars spin bearings and break parts. However, if your not spraying much you should be ok. Nothing is a deffinate or given though.
With a 150rwhp shot on 93 octane I run about 24* of timing and run that A/F ratio at 11.0-11.2. On a 200rwhp shot I run 24* of timing with a 93/104 octane mix with the same A/F ratio.

You'd probrably be ok but it might be border line. I used to run about 26* of timing at the track with Sunoco 93/100 octane mix and I would get 1-2* of KR sometimes (had a shitty tune at the time though). Just mix in more race gas than pump gas.

Yeah I ment leaner than the guys running 11.2-11.8 range. But that does answer my question. Thanks
With timing is it safe to work up to where you get 1* knock and back it down a few * past that? I wouldnt think about running above stock but if my car will handle -2* timing on a 150 w/o any sign of knock would that be ok? I know its kinda dangerous but im going w/ forged internals soon anyway. I know bigger things could happen but what do you suggest?

We reccomend and target our a/f @ 10.8-11.2, with our systems.. Especially if you want to keep a stock bottom end running for a long period of time.. That's my overly rich .02
