where do you work that you have access to a shop & machining tools?

I am interning at Ceriale's Automotive in Mt. Holly, NJ. I learned how to turn rotors today, but no one has done a flywheel so that'll be a first if we can figure it out with mine, the machine is made for it so it should be fine.

Thanks, I'm excited about this, in a second I'll have a gearing post and then the stuff I promised earlier,

Calculations done here and gear ratios retrieved here!

Thanks to andrew bense for the help here, for those of you that know him.

EDIT: Damn formatting, my eyes hurt!

Sounds like you broke the pintle cap on one of the injectors SVO. They are designed to protect the pintle...you'll be fine without it, as long as you don't drop it again.

If the injector pintle is clean, the spray pattern is already idealized. Honda injectors use a pintle (sort of like a solenoid operated needle valve) instead of a disk to open the fuel orifice. Essentially an injector is just a solenoid. Increasing fuel pressure won't do a whole lot for you. Increasing a little will allow more fuel to get through the orifice during PULSE ON. Increasing the fuel pressure too much can hinder the injector's ability to open (just think, if there is 100 psi, this injector first has to push back against that to open the orifice before it allows any fuel through) and actually cause a lean condition.

Didn't even have to search to find someone 10x cleverer than me. Too bad my auto to manual swap is gonna get done before his,

Thanks for the pintle information, Daxxxy, but I figure I'll replace it anyway since I can get a free set from a friend and the one does have a bad o-ring,

Ben your 5th is exactly like my 4th. Once I get some taller tires I'm hoping to be 2000rpm at 65mph instead of 2200rpm where I am right now with smaller tires. My stock tires allowed me to be at 2100rpm at 65mph. I should have never went with smaller tires.

[SVOboy]

Do you know what your final drive is? I knew we had the same gear size there but I never knew what your FD was.

[Compaq888]

It's 3.619

My current tire size is 205/60/15. As you can see by the calculator when you calculate I made it worse for me.

Woot! A 192 MPH car that gets 70MPG! Dood! you are my hero!

[Compaq888]

boost and lots of it. As a matter of fact I seriously doubt even with boost his car will achieve that. Gears tend to break up under a lot of power. The only gears that will hold up to a lot of power are the 1st 2 gears. They are built to withstand a lot of damage. The strongest gear in a car is actually the reverse. You ever notice that is makes a loud noise when you go backwards, it's because it's straight cut. The straight cut gives it the best durability and strenght, the problem is it's very loud. Race cars now only use straight cut forward gears. Gears are cut at an angle in common cars for the forward gears to reduce noise, plus most cars are not that powerful.

dude on reallly really super low speed technical auto-x courses, you would never have to get out of 1st gear!! im telling you race h stock!! hahaha
