Haha word. You've only seen it once? I actually use to service the entire town of Warrenton when I worked for Pepsi. I'd be at Bloom, Safeway, Sears and Giant on a regular basis everyday.

We'll have to meet up sometime. (no homo)

 

u guys are goofy man.. 58k is nothin..i ran my old cavy hard and i had 130k on it..58 k is just gettin used to the motor.

 

Yeah I know, but I probally won't get there early enough to get my car on the dyno w/o having to wait in a big line. Mind you, you live im MD....I live in VA. I'll probally roll up with the GMU wolfpack again this year.

Plus, i'd rather my dyno numbers be more personal........not exploited to everyone.........just in case they suck

lol well I mean I see so many damn SS and SS/SC's that are the same year as mine with like 20k-30k on them. I'm so damn jealous! I got mine brand new......but I drive it ALOT.

 

well sorry twice haha but if u see my car near frosts means im at work there at booth feeds...stop by anytime

 

Word, will do.

Also, are you coming to the giant D&B meet i'm hosting on April 26th?

 

i dont kno for sure yet. i didnt post anything in that thread yet because i wasnt postitive was goin to be able to make it

 

Oh alright, gotcha. Well let me know when you find out more. I'm trying to assemble a decent size wolfpack to roll up together. So far its me, Bad05SS, occsdude and theres two SS/TC's (one is thehov, can't remember the other's username) from Manassas that i'm trying to get to go with us too.

Oh, and sorry for thread jacking so bad Zdeuce!

Back on topic! lol

 

haha ill let you kno.....so wheres the cams at hahaha

 

today is supposed to be ship day.

 

Nice dude.

 

I really wanna see the numbers with the cams. If I every get it feeling good again then I may need to pick up a set.

 

I wanna see a before and after dyno with the cams. I know Justin (cobeeezy) made 212whp w/ his cams, but I don't know what his numbers were beforehand.

 

since i got a baseline it may work out still.. im goin back to the same dyno and they save all dynos.. if i dont get a chance to dyno just the bolt ons and tune then when i get the cams installed ill get that dyno afterward for sure.

im getting real annoyed with the shipping cuz i paid for them almost a month ago. jbp said theyre still waiting on the lifters to show up.

 

On our dyno testing we found that after a bit as we added mods, the vacuum in the intake manifold was increasing. This indicated that more power couldn't be made without a change to that system. It will be interesting to see how your dyno turns out.

 

God I wish that cars weren't so damn expensive. I'd like to do a new intake mani and cams on my car but regular maintenance is killing that right now. Also have the spray that might not even get hooked up this year.

 

On a 2.4?

Perhaps it was choked at the throttle body? The 5.4L envoy swap or SS/SC TB might correct it.

I wonder how the hahn would flow in a NA application.

 

if i stay NA i plan on getting the Vulcan intake w/velocity stacks..should cure that right up

 

Tell me about it man. And on top of that, I don't even have a job right now to do the regular maintenance

 

at 58 k u shouldnt be having too many issues...wuts the deal? Tires and brakes are the only things that actually put a dent on me for my previous car..you do got 19s tho..id hate to have to replace 19" tires.

 

Yes, on a 2.4. There appears to be an issue with port length and pulse tuning. Probably another with plenum size. We're working on solutions but it could be a bit before we get to dyno testing again.

The Vulcan 2.4 intake has 4" runners, that is very short and I'm not certain how that would perform. I'll see if there is a calculator for that.

*Edit*
For 2nd harmonic, RPM range is from 29370 to 35640 with a pulse strength of 10 percent
For 3rd harmonic, RPM range is from 22068 to 25220 with a pulse strength of 7 percent
For 4th harmonic, RPM range is from 17205 to 19240 with a pulse strength of 4 percent

Looks like the 4" runners won't work well.

**Edit #2**
I forgot to add the 4" of intake runner in the head and I have factory 2.4 intake #'s.
The factory runners appear to be approximately 17" long. So factory total is 21" compared to the Vulcan 8"
This puts the tuning here:

Stock
For 2nd harmonic, RPM range is from 5594 to 6789 with a pulse strength of 10 percent
For 3rd harmonic, RPM range is from 4203 to 4804 with a pulse strength of 7 percent
For 4th harmonic, RPM range is from 3277 to 3665 with a pulse strength of 4 percent

Vulcan
For 2nd harmonic, RPM range is from 14685 to 17820 with a pulse strength of 10 percent
For 3rd harmonic, RPM range is from 11034 to 12610 with a pulse strength of 7 percent
For 4th harmonic, RPM range is from 8602 to 9620 with a pulse strength of 4 percent

 

But what you have to remember is the pressure waves can travel up and down the runner numerous times before the valves open. So well they runners may not seem the right length at first as long as overall correct length is divided by an even number the pressure wave will still arrive back at the valve when the valve is opening. So the harmonic range is probably less then what you have posted. The only real problem with the Vulcan intake manifold is the plenum is to large an N/A application. Hell the factory manifold's plenum is to large for it's application. The real issue with these cars is the exhaust ports are hella to small creating the true restriction, not the intake manifold or anything before it.

That's a good simple read on intake manifolds. A lot more could be learned in books.

 

1. yes, i understand about the pressure waves. hence why my post lists 2nd, 3rd, and 4th harmonic. Beyond the 4th the gains are so small it wouldn't matter if you hit it right. Each time the wave travels up and down the runner it loses strength. That's what those percentages at the end of my chart indicate. You can extrapolate to a 5th pulse but you'd probably only have a 1 or 2 % gain. Not enough to make changing intakes worth it. not when the factory intake hits the 2nd wave when it does.

2. You cannot have too large an intake plenum. More is always better. Diminishing returns but there is no such thing as too large.

 

are u two telling me that im not gonna gain any power with cams?

i want the manifold to have something a bit stronger when i spray..ill be adding a 75 shot

 

i have no clue what you guys are talking about

 

The biggest gains would be from a port and polished head.

I slightly misunderstood what you posted at first zoomer. My apologies.
