We cant assume he is going to know? So we assume he cant drive and then go into the race with that on our minds? I personally prepare to race the fastest of whatever Im racing (whether it be an Fbody or a 10 speed) and in this case the best would know how to launch and would cut a MUCH better 60'.

With a stall and a gear vs a good driver he will be humiliated, as not only will he be out launched but he will get stomped on the top end. At least with the nitrous he has a chance to reel him in, and you dont have to tell him your spraying!

Oh well I would put a 125 shot car vs a stalled and geared one any day of the week!

.3 tenths wow man!!!

nitrous will knock more then that off, shut up, you're wrong...

Brodyscamaro, aside from your wonderful manners, kindly explain why you feel that dropping three tenths with just a stall, and gear swap, is bad? Is this some incoherent babble on your part disguised as some coherent point?

Maybe you didn't take the time to read the thread? Dunno, but I've stated many times that nitrous is an excellent power enhancer. However, on a stock LO3... exactly how much faster do you think it's going to go (from 25 seconds, to 23 )? Do you even have an opinion, or is "shut up" the way you justify such a response...?

25thmustang, I'm glad to see that your so ready to street race, and that preparation is a must in your book. You yourself have a very respectable ride, and you cut some very good times, but we're talking about an LO3 here. We all can sit here and speculate, but the race obviously needs to happen first....

brodyscamaro

Not too bad man, but please know that many people have dropped 5 tenths from just a converter.


I did.

Probably more then .3 seconds faster. 100 shots have been known to shave 1.5 seconds off the quarter. I know a 100 shot shaved 1.5 seconds off my quarter mile time in my 4100+lb truck.

Why won’t you just listen to what the more knowledgeable people are saying? A nitroused LO3 has a better chance then a stall/geared one. Period.

Let's recap for all you nitrous buffs;

Okay, I'm not too sure about that second shift launch, but this sounds about right even if he were in first. Five to six car lengths lmao, exactly what do you think nitrous is going to do for him? Okay, so maybe he loses by 3 or 4 car lengths next time using nitrous, this doesn't change the fact that he'll lose, again...

I never said that a stall and gearing will help him win, I merely said that at least he'll make it more interesting by keeping up with him in the sixty foot. Obviously, all three mods would be a big improvement over stock, but guess what, he's still going to lose...

It's been interesting though...

25thmustang

I dont street race, but know a lot of people who do. I just say dont go into a race expecting the other guy to run a slow time. If you do this your going to get beat.

If your set up to race a car that runs low 14s with a good driver or high 14s with a so so driver, what are you going to prepare for? You going to get your car ready to run a high 14 car or a low 14 car???

He is going to play catch up, might as well give himself the power to do so!

25th, understand that I agree with what you are saying. But try to understand what I'm trying to say. Putting the drag strip, as well as planned street races on the side... a lot of normal everyday street racing happens on the fly, especially in traffic. We live in a society with varying speed limits, and its rare for people to truly go the speed that they want (especially in major cities).

I don't think I ever hit the juice on the street, when it wasn't actually planned for that is. However, having a stall and steeper gears helped a great deal in launching with the AWD'ers (and their everywhere here). If this thread were titled, "LS1 vs Dodge Viper", then you better believe that nitrous would be my first suggestion. But with an LO3, well, if it isn't going to provide a win... might as well try to go after the AWD'ers for what they are known for, awesome launches...

Brodyscamaro, listen, it's all good. I know what you are saying, and I agree with your views. But try not to dismiss other people's views without knowing the true intensions behind them first....

I tried to be as elaborate as possible. Peace fella's...

i dropped 5 tenths when i dropped a deuce

CrazyBear

vinceanity92 that's pretty impressive how many times did you have to flush for that one?

lilbowilson

iTrader: (2)

A viper can put 5 or more lengths on a stock LS1 and you would use nitrous for that race but not a L03 vs a modded talon that might run low 13s? Why not put on gears and stall first for that race too so you could look better on your 60ft.?

Man just face it your not going to win this argument.

Blu91Z28

Street Lethal, Considering the LO3 is peak rated at an anemic 170 HP @ 4000 and 255 Ft. Lbs. @ 2400, what gears and stall would you suggest? You mentioned something deeper than my 3.23's. Maybe a 4.56? Of course you'd be stopping at the gas station as often as you'd have been filling the nitrous bottle.

first off i launch from a 50 roll in 2nd gear not from a stop in second.

i didnt race the kid yet.

i raced a G6 that used to beat me last night using my 100 shot and i put bus lengths on him this time so today im racing the tsi this afternoon.

25thmustang

I understand what your saying, but also remember this...

Most people wont street race from light to light, from what I have seen. Most street races happen from rolls (look at where Vipershark lives and see he talks about racing from rolls) or last more than a couple hundred feet. Personally I would build the car to run the nitrous first, but I am responding to this argument and in this case the nitrous is going to be smarter. The race is going to be about a 1/4 mile, and the AWD car is going to outlaunch the L03 no matter what!

In the real world Id drop a 5-speed in, but thats just me.

ok i was messing around with the tsi early this afternoon on my 100 shot bottle pressure at a low 800 psi. we launched at about 40mph so i had to wait till 50mph(3000rpms) to start spraying so he got a head then once i hit the button i started pulling hard on him.

after i raced an 01-02 rsx with an intake and exhaust. we did it from 50-110 and i beat him by about 5 car lengths. 2nd race we went from 30mph and i left at 4500 rpms so i could only spray 500 then i shifted into OD then sprayed through the weak at 4200 rpms shifts my car does and beat him by 4 cars

tomorrow is the big night im upping my jets tonight and ill let you know how i do against cars

lilbowilson

iTrader: (2)

Well did you beat the tsi or not you said you started pulling hard but did say how the race ended. How far did you beat him or lose to him?

1991CamaroRslow

iTrader: (3)

Race him from a dig! Are there no isolated roads you guys can go and have a flagger, or a passenger count down? And why are you waiting until 50mph to spray? That 3000 rpm thing is a suggestion, I've never waited that long to spray my car. From a roll you should be spraying it a SOON as the horns honk and you take off to take full advantage of it. What jet combo are you running in it now, and what're you moving up to out of curiosity?

vipershark11

iTrader: (6)

maybe ill spray at 2800 tonight i just dont wanna backfire that ****. but i was coming up on the tsi real hard after he got about 2 cars on me then we stopped at about 70 80ish. my old jetting combo was .030 fuel and .050 nitrous. my new combo is .031 fuel and .055 nitrous. i used a calculator and .031 is what i should use but last night i used .035 fuel with the .055 nitrous and it was running way way way rich so im stepping it down a lot

1991CamaroRslow

iTrader: (3)

How much fuel pressure are you running? Do you by chance have a TPI style pump in the car? By my calculator which I consider to be light on the fuel side a .055 jet should use a .040 jet at 15psi fuel pressure which would give you right at 100whp (nos jettin scale). I wouldn't be afraid to run up to a .065 jet. As for spraying at 2800 you'll be fine as long as the car has good plugs (non platinum!) that're gapped to about .035, decent plug wires, and good gas. It's not spraying to low that makes them backfire, it's usually over revving and hitting a rev limiter, something our cars don't have until WAY up in the RPM band. Also your lower RPM shifts will actually help you out on the bigger nitrous shots, nitrous makes more torque at lower RPM's. Good luck on the run man!

vipershark11

iTrader: (6)

i dunno im screwed up ive been told i have 45psi fuel pressure which would mean i need a .031 jet but then im told i have 11ish psi which requires a .4something which i did calculate i dunno which to use im gonna go pull some plugs and see whats up in there. then ill adjust according to that. i was told but a smart guy i was in the 45psi range and my injectors are 20something pounds each so i dunno test n tune.

1991CamaroRslow

iTrader: (3)

He's dead wrong. You're injectors are way bigger than the 21psi injectors on a TPI car and your fuel pressure should be around 15. The TBI injectors will run higher pressure but they're not supposed to. I would imagine your car has 15psi. For your .055 jet I would recommend a .041 jet or a tad bigger for safety. Nitrous will run lean, and make good power but you're risking your engine, especially as lean as that shot was. What jet's do you have for the kit?

1991CamaroRslow

iTrader: (3)

Your injectors are a pair of 44lbs/hour units, your fuel pressure could be anywhere from 9 to 20 depending on how the regulator came set from the factory and assuming it has the factory pump still. The specs he gave you were for a TPI car which has 8 21lbs/hour injectors for a 350, or 8 19lbs/hour injectors for a 305, those cars run the high pressure pumps that put out 45psi, most actually run closer to 35psi at idle and 40 at WOT.

UPDATE

i raced the tsi last weekend with 125 jets and no warmer so bottle pressure was at about 700-800psi after about 2 runs right before. he beat me by 2.5 cars. this weekend i got my 150 jets and a warmer and i raced him again first run he got a 2 second jump and i caught real fast and past him then hit speed limiter. second run was from a 35 which is his cars strong point. instantly i pulled a car on him and by 100 i had about 1.5 cars on him. boo ya to new jets and warmer

1991CamaroRslow

iTrader: (3)

Nitrous rules.

lilbowilson

iTrader: (2)

Well I guess it went from a 25 sec to a 13 sec car! You can come back on this thread and say you were completely wrong about stall and gears are better than nitrous on a LO3 anytime you feel like it.

I guess that TSI wasn't a 12 sec monster after all with that 150 shot at best you have about 250hp at the wheels. That should make your ride a mid 13 sec beater.

vipershark11

iTrader: (6)

sweet im going for some nice SHO payback tonight if i can if not itll be mustang killin for sure. nitrous does own worth every penny

1991CamaroRslow

iTrader: (3)

viper your jetting is actually what I would call a 130 shot. A 68 or a 70 jet would be closer to a 150 but with your setup I'de say you're at the safe limit's at the time so stick with it and keep kickin @ss.

z28z34man

My next mod would be dual exhaust if you don't have it already. More power, better gas mileage, and a nice exhaust note. Can it get any better?

vipershark11

iTrader: (6)

o well i thought it was a 150 cause i used an online calc and it said it was 160 hp at the crank and 140 at the wheels for the 61 but yea i dont plan on stepping up anymore unless a new fuel pump somehow magically gets in my tank. but thats ok you really think id run mid 13s?

freestylzz

1991CamaroRslow

iTrader: (3)

That would be my guess, high to mid 13's.

i raced an ls1 98 z28 with a lid, gears, catback, and a short throw shifter. we raced first was from a 30 and we were dead even he went to shift into 2nd im guessing and missed. second race from same speed we both jump hard and he pulls a little and at 90 hes a good 3 cars ahead and not pulling as much and i let off.

then i also went to race the 94 V6 5 speed SHO with solid motor mounts, 3.2 block with 3.0 cams, and catless y pipe. we go to go from a 45 and right as the race starts i get on it and we were dead even till i felt a major drop in power after 3 seconds. i think i ran out of liquid being siphoned the way the bottle is positioned so i just let off the button and hit it again and it didnt feel right just like i had it floored w/o the bottle open so next weekend im gettin it topped off running at 1000-1100 psi and i should beat him hopefully hes getting scared because everyone is bettin on me. i should win right?
