Well, my nitrous still isn't working worth a F**K
But the day wasn't a total waste, I did beat FasterDamnit 2 out of 3 and out E.T.'d him on the last one (12.18 to his 12.19), but my reaction time SUCKED so I lost

Best pass of the day on motor was 12.07 @ 112.19
Best pass of the day on the bottle sucked ass 11.47 @ 116 ?!?!?!?!
For some reason my nitrous wasn't working in 3rd or 4th gear (at least that's what it felt like) I picked up a WHOPPING 4 mph on a 200 shot

Looks like I am going to rethink my plans (once again) May have to sell off the nitrous after I figure out what I am doing wrong (don't want to sell someone a kit that may be defective) Sell the GT-40 intake with both uppers (I have a Downs box for it too) Give in and finally buy an Edelbrock RPM intake and shoot for 11.80's on the motor all day long

We'll see, I change my mind more than a woman

what kit are you using ?

So is one of the uppers a stock one? What would you be looking to get for it? Let me know...

Yup. Brian can drive!

The track prep was good but the surface for the first 100ft had lots of rubber chunks coming up. It really needs work. My best run of the day was a 12.06 at 113.27 on a 1.70 60ft. Brian's launches on the 200 shot were forays into serious tire spin. Not to mention his escapades getting sideways on his shifts. Think we need to start calling him "Animal"! My last run of the day a damn chebby camaro went before me and hosed the top end w/ coolant so my right rear spun BAD in 4th and I got sideways at the lights. That was enough adrenaline for one day so I want back to the pits. LOTs of runs, no waiting. Just needed a better surface to race on.

Don't sell yourself short, that save after hitting the coolant @ 110+ was a damn good piece of driving !!!!

I got to thinking about proper runner length for your 331 Brian.
If you don't mind the advise, here it is.

Victor 5.0 intake with a 1 inch spacer.
This will give the optimum 14 inches of runner length for your setup. Another option is the RPM 2 intake with 14 5/8 inches of runner length & tappered runners (for higher velocity). The RPM has 15 inch runners & no tapper & it's my opinion that the ports are a little small for 185's. I believe the GT40/Cobra intakes have 18 inch runners without spacers, but I could be wrong....it may be as low as 16, I can't remember.

nah even for most 347's the victor is too aggressive for the RPM range in use here. making power to and through 7k rpms? sure go with the victor on your stroker.

Wasn't Camara using an RPM on his 347 w/185's? Seemed to work pretty damn well with his motor
The RPM II is, well.... Not worth $600
The other thing is that the Victor has no provisions for EGR. While there are other non smog legal components on my car, an EGR valve is a MUST when driving in Redding when it's 115 degrees outside

Posted by 93PONY (Member # 60) on :
 
Camara's motor peaked at the same RPM with every setup from the AFR165/X cam combo to the last one. The last setup would have made significantly more power with a Vic 5.0.

If you don't run a smog pump there is nothing going through the EGR valve anyway.

Just a suggestion.

not kidding at all, I could reference many-a 347 that lost power moving towards the victor intake (from a rpm or holley), but one person in this thread already has their mind made up and doesn't care.

edit: at least not without a cam swap, and some substantial reductions in sub 4k rpms performance

Shaun the statment about the air pump and egr is NOT correct. do a little more reading then it should be clear

LOL, I was thinking the same thing

The air injection system has absolutely NOTHING to do with the EGR system
The air pump adds air to the exhaust system to help aid in the reduction of emissions by promoting additional burning of the leftover CO and HC AFTER it has left the combustion chamber
The EGR (Exhaust Gas Recirculation) system allows a metered amount of exhaust (an inert gas) to enter the intake tract, be distributed into the cylinders, cooling the combustion chamber, reduce "pinging" and lower NOx emissions

Food for thought

Me think's somebody should take some smog classes to learn what components effect engine performance and emissions.

Mike's last setup with the RPM manilfold made peak power at 6k RPM.

and it was a fully ported rpm if i remember right, maybe not fully ported but it was ported

---

And it is FULLY ported

I can always count on those professional mechanics to rip me one when they get a chance! A, what the hell, I'd do it to them too! Hahahaha!

You guys are right. I got a bit confused with the pipe between the heads that runs to the smog pump. I forgot the one-way valve runs the OTHER way, not to the pump. LOL

Where do you get this tailwind stuff? Is this another of your false accusations or something? Don't worry about me running. I didn't plan on it. I was there to watch my buddy with his 01 SS. Like I said before, I'll be there the 17th and ready to run then You are going to make it right Oh, I will be trying my Nitto's as well as some ET Drags. Don't complain about my tires because the last I checked all the other mustangs were running slicks too!

depends on weather and if Brian goes. I don't have slics or ET streets for my 91. Just Nitto's I don't need to change anything on my car from how I drive it every day.

I know it overflowed from the corral to here. Let's hope they can play nice together at the track next week. Or it's timeout time

since when is exhaust gas inert?
there is unburned fuel (HC or Hydrocarbons), Nitrogen oxides (NOx), etc.

i WISH exhaust was inert...then i wouldn't need to get my car smogged...

Sac Raceway has a notorious tailwind which can have a pretty big effect on ET/mph. steady 20 mph winds with 30 - 40 mph gusts are fairly common at sac and would negate any record speed runs in REAL competition. that's why they run both directions at Bonneville Salt Flats...it helps negate outside influences like wind, slope, etc...

i got a 122.4 mph pass at sac... i think it was wind-influenced and several mph off what i typically run (116 mph) which makes it suspicious to me...what i ran yesterday makes little difference to how i'll run tomorrow, or in 5 minutes from now...wanna race?

Since that's what they teach us in Smog school

Due to the fact that the remaining HC and CO are not in the proper ratio to promote combustion, it is considered an inert gas. It is basically a "filler" used to reduce cylinder volume by taking up some on the room in the cylinder so less air and fuel will fill the cylinder.

After 11 years of being a smog tech, I have actually started to remember some of the sh*t I have been taught

I was at the track when Aaron's car ran it's best ET/MPH to date. There was no tailwind & the air was warmer then it is now.
On that same night Heather's car ran a best of 12.22 @111.3mph with Drew & a best of 12.4 @110.8mph with me. I have since backed that up with 12.18 @111.9mph & Drew with a 12.08 @111.8mph with no other mods aside from tune.

Aaron's car pulls Heather's on the street every time. His car dynoed 25hp higher then hers on the same dyno on the same day. Considering this & the track times on the same day at the same track, his car ran what it should have....& I can't wait to see what it does next time out!
