Purge Kit and Bottle Heater

[Silver3800V6FBodyKY]

Hey Guys, I just bought a NOS 5175 Kit and I need a couple more items before I install. I need the part numbers for a NOS Purge Kit, and NOS Bottle Heater that will work for the 5175 kit. I'm going to order an Ultra-Lite Autometer N2O PSI Gauge soon too. Do you guys have any suggestions as to what else I'll need - like maybe Plugs/Wires? What jet should I use at first, and how is the N2O going to like my 4.1:1 Rear End Gears?

Thanks

You have 4 10's and now you plan on juicing?
If you juice off the line and hook eventually you will grenade your rear.
Nitrous makes tons of torque!!!!
I've got weeney 323 gears and I need mickey thompson et streets to hook and I pull a 1.630 60 foot.
Just imagine what I could do with any higher gears?!?!?!?!
I'm not a fan of higher numerical gears with a nitrous car.
You might want to reconsider that.
All you will do is melt your street tires.
I can't get my nitto drag radials to hook for sh*t anymore.
Also remember, you have a speed limiter, I had 4 10's and when I had the speed limiter it would hit at 85 mph due to the speedo being off. My car came stock w/ 308 gears.
ngk tr6's
I like accel extreme 9000 8 mm
'stock' jets or the 85 hp shot is fine
As for part #'s, they are universal.
Check the nos web site and go from there

Didn't Magnus run TNT with 3.73:1 Rear End Gears with stock rims? Right now I have true 4.1:1 Gears, but once I put on my 18" rims I should simulate somewhere around a 16" rim with 3.73:1 Gears, right? Anyway, I'll be running Nittos, and I'm buying a Moser rear end this fall.

What's the maximum jet you guys have ran without killing the motor?

Thanks

i just bought a remote bottle opener for 100 and know another person selling one for 100 shipped if you need one

A quick fix would be to get a reinforced rear end girdle for now. I'd also get taller and wider rims and tires for the rear, unless you plan on swaping to drag radials at the track. since you already have huge rear gears, the bigger tires will allow you more traction as well as better top end pull. on stock tires though, 4.10's are a bit big I think. what size gearing will you get in the moser 12-bolt? take into consideration the tire diameter you'll run w/ it.

OK let me explain something here about tire height, gear ratio, tire width etc.
Here is an example
Stock my car came with 308 gears.
I played with different gears (4 10's, 342's, 323's) and found out that 323's work the best for my application.
I run 245 50 nitto extreme drag radials on a stock 16 x 8 rim.
Tire height is 25.64 inches
To figure out:
245 50 16
245 mm wide, aspect ratio is 50 (50% of 245), rim is 16 inches.
Aspect ratio: 50% of 245mm is 122.5 mm
122.5 mm is also 12.25 cm
12.25 cm is 4.82 in (12.25 / 2.54)
Take 4.82 inches for one side of tire from ground to rim then add rim diameter of 16 and then add the other side from rim to tire of 4.82 for a total of 25.64
This is the correct tire height to give the effective ratio of 323's to the ground.
I found myself passing the 1/4 in overdrive with these tires so I went to a taller tire at around 106 mph.
I bought taller tires. micker thompson et streets 26 x 11.5's (or maybe 10.5's, I forget) mounted on stock 16 x 8 f body rims.
Same rim size and diameter.
This tire is advertised as 26 inches tall but is really 26.1 inches tall.
Adding a taller tire to the back plus the same gears (323's) gave a 'fake' 308 gear to the ground.
I then found myself passing the end of the 1/4 at the same mph but in a different gear. I was no longer just in overdrive but maxing out drive.

Now please explain to me how you will make 18 inch rims like 16's with tire height and effectively change the gear ratio to the ground

Magnus made his nitrous runs w/ 342 gears.
He recently put 373's in and has done n/a runs but no nitrous runs.
He runs weld drag lites 15 x 8 I think.

If a shorter tire height simulates a shorter gear, such as a stock Firebird with 16" rims and 3.42s changes to 15" tires and a porportional tire height, that Firebird should simulate a numerically higher gear ratio such as 3.55. Now since my car's gear ratio has been changed from 3.42 to 4.1 but maintained stock tire height, when I changed my tires and put on taller tires, I should be simulating stock tire height with a numerically lower gear ratio. I'm not sure how much lower, but it won't be a true 4.1 to the ground. I'm hoping it will be somewhere around a stock tire height with 3.73 - 3.8 ratio, but I'll have to get my formulas back out from Precal and Physics and tell you for sure what I'll be simulating.

[12secondv6]

I hope you didn't take my post wrong, it wasn't a bash but an explanation.
Usually when you increase the rim you run a shorter sidewall
245 50 16 = 25.64 inches tall
275 40 17 = 25.66 inches tall
I run these sizes on my bird.
We are talking 0.02 inches difference in height.

[Silver3800V6FBodyKY]

My Tire Height now is 26.1".
(235/55/16)
My Tire Height with 18" rims will be 27.5".
(265/45/18)
1.4" is a considerable difference in diameter.
A 26.1" tire has a circumference of 81.95"
A 27.5" tire has a circumference of 86.35"
That means for every rotation the rear tires make, a 27.5" tire will move the car 4.4" farther than a 26.1" tire. I think that's enough to considerably change my overall gear ratio.

If I do end up changing my gear ratio, I'll move up to a 3.73:1, because with a 27.5" tire I should simulate a 3.42-3.55 gear w/stock rims.

[Silver3800V6FBodyKY]

Ok, I found out my simulated gear ratios. With 27.5" tires, I will be simulating a 3.9:1 gear ratio. That will be my street setup. When I go to the track, I'll put on 29" tires and I'll simulate 3.68:1 gear ratio. Both of these will simulate a stock tire height of 26.1" with different gear ratios. I think it's fairly safe to spray with 3.68:1, I could be wrong though.

[12secondv6]

Yeah but you are missing one important thing.
Have you ever looked at a pro stock car like john forces?
Small rims with really tall tires.
Huge amount of sidewall on the tire.
You are adding a bigger rim and smaller sidewall.
You can compensate all you want with a bigger rim but there is no way in hell you will ever get an 18 inch rim with such a small sidewall to grab w/ those gears and nitrous.
Take a look at the track next time.
Take a look at all the fast cars.
A majority of them are stuffing smaller diameter rims in the back with taller sidewall's on the tires.
This gives it a wrinkle effect.

What james its trying to explain is this...

Take a Rolling pin made of wood. and try to roll it on a rough surface.. you will notice since it is more rigid(the smaller sidewall doesnt flex) that it never makes full contact with the ground. Now take a rubber rolling pin and notice that it conforms more to the rough surface. This is what a taller sidewall does. it allows more conformity so that the tire contacts the ground with more force. I hope this makes sense. A smaller sidewall'ed tire would be ideal for autocross because the sidewall doesnt flex very much, but drag racing and so forth requires a tire that can flex and wrinkle so it will maintain maximum contact to the ground.. (look at dragsters)
