So I won't need the purge valve that I have now?

You will need to keep that to purge at idle, launch, and mid rpms. No valve float in those ranges.

It should sound like about 625hp/650ft lbs.

That sounds like traction problems to me.

Oh yeah. Good point.

Launch in 4 low, duh.

 

[rnaz]

I guess I could, but won't I hit the red-line before the end of the track?

No, LOL 4 lo launch in first, then shift to 4 hi/1st. Then 4lo/2nd followed by 4hi/2nd, then in 3rd keep it in 4hi.

I'll have to play around with that before I go to the track and embarrass myself by missing a hi/lo shift.

Get a Hi Lo Kitty Hawk shift timer.

 

[haulndak]

That Kitty Hawk timer is junk. I will never put one of those on any other vehicle I own. Kyles Kustoms sells one thats a alot better. It has 12v outputs to run a nitrous controller.

What the fuck is that?

Maybe I don't need a forged crank for my 390 that is going to get sprayed.
I should just use a cast crank, and let it flex under the added cylinder pressure from the nitrous.

absolutely!! Forged cranks are retarded!
Every crank has a tolerance spec. With a cast crank you can be out of round as much as .608580" due to the flex factor.
Plus my machinist told me since mopar spends a bazillion dollars on advertising they dont have enough money left on the table to develop a quality product. So instead of using exact tolerances they just give a range to use.

Race Pro Crankflex program!

Correction... Desktop Crankflex PRO version 3.8!!! The shareware version is not that good!

 

[TurboBlew]

it depends on which side of the vehicle you want to pull off the ground. most people get the right side of the block to produce most of the power so it will lift the right side tires.

dude why dont you just type up a small book and distribute if over the internet if youre going to give away speed secrets like that!! :argue:

That makes sense to me.

Or just run 1.7 rockers on the right side.

Actually if you run a 1.5/1.9 rocker ratio it equals a 1.7. And plus they cost 1/3 the price since those are standard chevy rocker ratios!

 

[Devilbrad]

What the fuck is that?

Some Japanese company owned by Hawk Brakes. Very popular in the Japanese market.

Good point! Rocker ratio averages should always be concidered in any build.

Well, my truck is a 4x4, so maybe I should be thinking about the left side instead of the right side.

Fuck. That changes everything.

Its all about math...

4x2 = 8 Now you take that number times 3.14489577794 (otherwise known as pie) Is it coincidental that dakotas have V8s? Not according to my math.
Anyway the final product cubed (this is where cubic $$ comes in) is going to be your horsepower rating

Jeeps are a whole different equation.

4x4 = 16. Obviously jeeps dont come with 16 cylinders. So you multiply by 3.14489577794 THEN find a prime number between 0 and 100 that is evenly divisible by 17. Remember to SHOW ALL WORK because if you go to the track, NHRA is very strict on enforcing these equations. If you have an iPhone there is an ap for calculating these numbers. Also Hughes engines has an excel program that does these computations as well!

My truck is not made by a Japanese company.:nono:
There will be no parts of that sort installed.

Ok, now I'm really fucking confused.
I'm just gonna say fuck it and have the motor done for me.
