Didn't quite produce the results I expected.

I didn't have an AMSOIL filter element for the base I used for the ram air, so picked up a paper element. First run Friday night was a little slower than the 650 & open element. Took out the paper for the 2nd run, now it's back to the 650 times.

As I went rounds in eliminations and the air cooled off, kept getting quicker & quicker. Unfortunately, the guys who have weather stations that I mooch off of went out early and went home. So, no DA for comparison. At least there wasn't any wind. Last run at about 10 p.m. produced the new best as in sig (redlight loss).

Today, went out again. DA was similar to last week w/650. So were times. Got a little better after a couple of rounds, but I didn't go many rounds today.

I think the drop base is affecting the flow. I'm going to try back-to-back with the ram setup & open element at test & tune next week to see what's what.

I had so hoped for that first 13-sec timeslip at altitude...

man you are so close to the 13s .....nice work. any difference in 60 ft times? did you gain any mph?

i am thinking about getting a 650 DP for my TA with a 350, 700R4, and 4.11s. it has the stock q-jet right now.

With the new converter (majority of runs with the 650 were with 2200 stall), I was pulling 1.97's to 2.00 with the 650. With the Proform under similar conditions, 1.96-2.00. When the air got good Friday night, as low as 1.94. MPH no real difference under similiar conditions.

Quantitative comparision data is very hard to come by.

I picked up an air horn -> air cleaner spacer in an attempt to move the air cleaner lid away from the air horn and give a straighter shot into the air horn. I also picked up an AMSOIL filter element, which is slightly taller than the Fram CA136 and allowed me to use high density weather striping on the lid to seal it to the housing and provide more spacing between the base & lid (~1/2").

The filter element also fits my open element cleaner. So, tomorrow at Test & Tune, I'm going to make a run with ram air, switch to open element, back to ram air, back to open, etc. The only variable will be the cleaner housing type (I won't use the spacer on the open element, either). We'll see what that produces.

If the open turns out to run better than the ram air, I can only conclude that the reduced spacing between the base and lid (because of the drop base) is the cause. If so, then I'll have to consider grafting the open element base onto the ram air housing - ugh.

i look forward to seeing the results of that test. should be interesting. i attempted to do a similar test with my car, however my test was to see if my modified LG4 air cleaner (baffles removed, 2nd shorkel grafted on, and a K&N) was restricting me. so i did several runs with the air cleaner setup and then did several with no air cleaner. i know, i know, this is bad, but i have never done it before and i wanted to see if my air cleaner was choking my motor, so that if it was i could rig up something better that wouldnt choke the motor but still provide all the filtration i need.

as for the results.....traction is a huge problem and consistant lauches were no in the acrds, its was so tough to tell, but i dont think the air cleaner was holding me back. next time when i hit the track....hopefully this friday.....i will have my cascar slicks or even some real drag slicks to hopefully eliminate the traction issue somewhat (the new 4.11s wont help, but hopefully the new posi will).

I'm in the left lane for both of these runs.

The best open element run was a 14.125 w/ 1.977 60'. The worst ram air run was 14.085 with worst 60' of 1.962 (not same run).

Density altitude hovered around 7800-7900 today.

(Edit: Attaching is giving me fits again. Hope it'll work correctly soon.)

spartyon

you have some good reaction times. what were the cars that ran next to you? so by your timeslip the ram air ran better correct?

darbleinad

hey hey...congratulations on the 13 sec time slips. great job. looks like that ram air helped. you may notice more of a difference because you are at such a high altitude that all the extra air you can get is good.

I chose very carefully which time slips to scan & post.

They weren't next to me long enough for me to tell...

I forget, actually. Both were door slammers, one an early Chevelle, the other a --- I forget.

They were just plain stink fast.

Those were both ram air runs. The open element didn't break into the 13's.

The most surprising thing was my 60's were better with the ram air. I pointed that out to a racer buddy pitted next to me, he pointed out that I'm feeding the engine cooler air from the get-go, so it should have better power off the line, too. Okay, so I'll call it "cool air induction" from now on.

i've been thinking of hooking some kinda divider up for mine.. so the carb only feeds from the cowl... but.. i'm just plain lazy.

When i go racing the first thing that comes off is the aircleaner.. and the vac advance. then the cutout.. then the lil rubber tube with the hole cut in it goes from bowl vent to bowlvent and i'm ready to rock

Yup, it's not "ram air", it's "cold air induction". "Ram air" is advertising copy, not tech speak.

But it feeds from the very front of the car - so it must be "ram" air...

Car was a little slower today, but I didn't mind too much with TT RT's of .006 & .008. In the Jackpot race, took out a mid-11 sec 2nd gen and a mid-10 sec 1st gen (chewing up and spitting out a Shelby Colbra inbetween). Then I go and bulb against an 11-sec 2nd gen 'Bird - who ended up runner-up. Oh, well, I was in the money (doubled the entry fee).

More tomorrow of the "big weekend" - if the rain stays away (not a promising forecast).

Saturday was a near total rain-out. Got one TT with 70% humidity late afternoon, ran 14.010.

Sunday morning - COLD! 49 degrees when they called us to the staging lanes at 9 a.m. for 1st round (no TT). Density altitude was 6300', the lowest I've ever seen it at Bandimere. I was in about the last 1/3 of the 84-car field, saw a bunch of guys break out in the early runs. Dialed a 13.99, my first sub-14 dial-in at Bandimere. Other guy dialed 13.97, ran a 14.09 to my 14.04 (he treed me by .06), Win #1.

2nd round was in afternoon, much warmer, DA up 1000'. Dialed 14.07 against a 14.92 in the other lane. Treed him slightly, caught him at 1000', fender-raced to traps but he was starting to pull back around so I put it down again - double break-out, 14.90 to 14.03 - I lose.

Had I run those two out, I'd have two more 13-sec timeslips.

I'm liking this combo.

(Oh, I added a .006 & .008 RT in TTs Friday, and a .014 in Jackpot race eliminations. Took out a 11-sec 2nd gen 1st round, 14-sec Shelby Cobra 'Stang in 2nd, 10-sec 1st gen in 3rd before bulbing in 4th round against the eventual runner-up.)

wow, so many race track slang words! lol, mind clarifying them?

break out
dialed in
treed (beat him in R/T?)
traps (finish line?)
double break out

heh, im sure i sound dumb asking what they mean, but i wanna know what all the big guns are talking about when i hit the race track!

p.s. nice times btw!

Break out - going quicker (taking less time) than you said you would. Double break out is when both racers do this - the one closer to their dial-in wins in that case, regardless of who crossed the line first.

Dial-in - your declaration at the start of the race, to the hundreth of a second, on how much time you think it will take you to cover the 1/4 mile. Typically written on the windshield, side window, and back window with white liquid shoe polish-like stuff.

Treed - reference to the "christmas tree" starting lights. A better reaction time. Reaction time is the difference between the green light coming on and your front tires no longer breaking the staging beam. Since the clock doesn't start your time until your tire clears the beam, the reaction time is critical in the race.

Traps - a reference to a "speed trap". There is a beam at the finish line, and one 66' before the finish line. The clock calculates your speed based on the time it takes you to go between these two beams.
