I ran a total of three times today. First off I just got my DynoMax 2.5" Cat-Back installed yesturday. My first run was with the exhaust and the stock air intake. The second was with the exhaust and the headlight taken out for better air intake. And the third was with the exhaust and a CCAI that I made last night with a huge K&N on it. Let me know what you think. My next mod though is the LSD from SLP and then the Cam kit.
1st Run:
R/T: 1.063
60': 2.366
330: 6.997
1/8: 10.841
MPH: 64.06

So what do you think?

1/4 times are great!!
Good for you
But the 1/4 mi. speed seems slow?
And you drove the car home, too!!!!
PS I really appreciate seeing how your speed increased with the increase of incoming air.
That seemed to ONLY WORK as you got over 60MPH

 

damn , thats great man ! ...is that a stick or auto ?

 

WOW

you got all the way down to the 16's!!!!!!!!! THATS AWESOME!!!!!!!!!!!

i gotta take mine sometime!!!!!!!

 

Great times! Mid 16's with only 2 mods. With a cam,catback,pullets,CAI,shift kit,Accell wires 8mm I ran a 16.18 @83. I later added 3.73's ad 3.4 headers, my 60 foot time got worse, and my time only went down a tenth to 16.09, but my mph wnt up to 85. Actually my best 60' was only like a 2.24 or something, so I think traction is keeping me out of the 15's, what do you think KED?

 

The car is a Auto. It also made a difference that when I first went to run my car was at about 190 degrees. That last two runs I pushed it and the car was running at around 120 degrees. Plus, living in Florida, it was hot out as well. Actually, they said it was the coolest day of the week, around 83-85, Though I do think the LSD from SLP will be the next mod I do. I want to get a little better traction. Then I will consider then engine mods.

GOOD IMPROVMENT. I THINK YOU SHOULD WORK ON THOSE R/T.
YOU WON'T WILL MANY RACES WITH .8 SEC. R/T.
LUCKY YOU. TRACK IN OHIO WON'T OPEN TILL APRIL AND I'M GETTING SHORT ON PROZAC.

Wow, those are some pretty solid times! Good job. Was the car a Firebird or a Camaro? Because if it is a Firebird how did you remove the head light? My best time with a Dynomax Cat-back, hypertech thermo-chip, MSD 6A, CAI, and Jet pulleys was:
Reaction.631
16.268@84.330

 

I wish I could quote ya.
I'm such a computer idiot.
What is a 3.4 header?
FROM MY UNDERSTANDING, the primary tube sizes are the same.
You are fitting that Header into a different chassis.
I THINK you lost bottom end torque at the expense of upper RPM/Horsepower.
Like adding a single palne manifold where there once was a dual plane manifold.
You loose bottom end torque at expense of upper RPM's & HP.
IN your case, also, this is the point of adding a higher stall torque convertor. Bringing the beginning launching RPMS into the engine TORQUE power range, INSTANTLY/QUICKER.
AND adding gears to your combo, took the engine outta the beginning power range. It launches ok, but, you note that your speed increased.
I'll bet if you put back in the 3:42, you'd be good. AS you want your end 1/4 mile speed to be in the PEAK HP power/RPM range (PEAK/RPM HP is @ 5250 RPMs)
BUT, I AM ONLY OFFERING WHAT I THINK, based on reading to many articles in my magazine library.

It really sucks to add all the things you've heard are "great" only to find, IN YOUR CAR COMBO, it didn't live up to the "others" claims.
PS only YOU know the traction answer. You can easily paint a WHITE LINE on the tire sidewall, have someone videotape launches to see results.
AND a COOLER ENGINE easily makes PRIMO power. Ice bag time, possibly?

 

I took the 3.4 headers made for 93-95 camaro's , heated them, and bent them with a pipe until they fit.

Is that the peak HP of the 3.1? My engine seems to be a little above 4000 RPM's when I cross the finish line in my 1:1 ratio in the transmission(3rd gear).

Sounds like a nice idea I know my car is much quicker than a stock 3.1, but I truely have no idea how well the mods did since I cant get traction. I think I will borrow my friends drag radials when the track opens up, so I can finally see if everything worked well. If my car hits a 15.90, or high 15.8 I would be happy.

I dont know why my car combo could be wrong? The headers ,exhaust, and intake should have opened the engine up to run better at mid -higher RPM's and the gears should have allowed me to stay in the power -band longer.

 

Thanks for the reply.
We'll have to let others gave input.
I could only offer what I felt was correct/a solid response/thought.
I THINK THAT
Icing down engine before a run will increase speed.
I think higher gears may be better
I do not know about your traction.
I do not believe you're generating enough torque to really make traction an issue.
How do you launch?
Trans brake the car?
Or just stab & drive?
These engines do not do well at RPMs abouve 4000+
Intake design limits them.
Anyone else have ideas to help our buddy?
How does the maifold to CC look? Smooth custom made or the original design?
What size are your intermediate exhaust pipes & the CC in & out?

 

you can really see the difference in the hook between the first run and the second and third runs. a little grip made a big difference. looks like the car is pretty consistant too, maybe yo shoudl bring it to the east coast nats hehe.
seriously though, those are good lookin times for such minor mods. give that car a big gear and a posi and you could prolly get into the low 16's.

good work

later
tim

 

hell if everybodys hiting mid to low 16's with minor mods i should be in the high 15's with all of my mods.

 

Yea your car looks solid. The Cold air intake you make dient do anything though. From what your numbers are I can see your reaction time "R/T" kept getting better thus an over all gain. If you could keep your RT similar then we could get an idea of what your mods are making.
a LIL shot of nos you could be 15's easy.

3.1 Firebird, those are pretty crappy time with all those mods on your car. Traction isn't that much of an issue for me I still have my stock 3.23s' in now, but I also have ZR rated tires also. I never got new times with my cam and rockers because as I said before the guy really messed up on installation, I lost to my brothers TBI after the cam. So when I get the cam fixed I have a TB, ported intake, Supercomp headers, custom burned super chip and 3.42s' ready too go. I figure my best before was a 16.268@84.330, when the cam gets straightened out and everything else gets put on I should be running low to mid 15's. Nitrous is a big possibility for a mod too.

3.1 Firebird, I think you should get an ignition set-up in your car and maybe a custom burned chip. Did you try to make CAI? Plus you should pull the 3.73's out and put 3.42's. You must be cruising at 3200 plus RPM in overdrive if you have an auto right. Those gears are way too much for a auto V6. Just trying too help, because I know what it feels like to be disapointed with modifications.

 

Well, the reaction time doesnt make any difference with the quarter mile time. If you were racing then yeah it would make a difference. But in the 1/4 time it doesnt make a diference. You could sit at the starting line for 10 minutes and the clock wont start until you leave the line. The R/T is the time from when the light goes off till you leave the line.

SETZER, you related to Ronnie Setzer? hell, id be excited to hear you guys are into third gen sixers. :lala: oh happy day!

 

Actually, I am surprised no one has ever asked me that before. Though, no I am not. Setzer is actually a character from Final Fantasy 3 on Super Nintendo. Sort of my favorite character.

~Josh~

 

And dont I know it

I was doing good with the cam,shift kit,pulleys,catback,intake,wires, because I was doing 16.18's. Add 3.73's and headers go 16.09. I;ve wasted so much money.

 

Tell me about it, the guy messed up on my cam and I wasted over 700 labor, but I'll get it fixed. I'm sure your car has more potential. I really think you need a new ignition set-up like custom chip and maybe put in stock 3.23's or 3.42's. Somethings gotta be done wrong. I'm sure you or someone else could find it out.

 

Setzer! The dice man! Yeah he was cool! :lala:

 

WTF??
i dont get it
my best time at Capitol was 17.1 in 1/4 mile bone stock
how come he does so much better then me when hes only got 2 mods?

(as of now i have CAI K&N and 2.5" Catback Flow 80 series new ignition coil new ignition module new timing adjustment and bald tires)

rock on third genz!!!:lala: :lala: :lala: :lala: :lala: :lala: :lala:

 

"My next mod though is the LSD from SLP and then the Cam kit."

SLP sells acid? Seriously though, it's 1am and for the life of me, what is the LSD that he's refering to?? ?

 

Limited-Slip

 

The third run is what I expect all yours should be... Believe it or not if you build up your traction, like LCA's, torque arm and pan hard rod you will drop down to 16.01-16.10 range...

 

So you are saying that if I build up my suspension I will get down to the 16.1 range? Well, I need to get new shocks and struts. Right now my car bounces when I go over a bump. Next week I am ordering KYBs. I think I am also going to let this machine shop place make me the custom tower brace.

~Josh~

 

Here is a little test we did.. Syxx put BFG Drag Radials on his car...He never broke under 17.03... 16.97 is what his runs were with them... Nothing else just a good set of tires designed for racin.. I now that is a lot to gain, but consider he runs 226 60 R15 and they are about half dead or half left however you wantto look at it..

My buddy with his 94 Z picked up time when he added LCA's and torque arm... Why cause hte car hooks up better.

You may not hear your tires slip, but even us little 2.8's are not getting all the power to making our cars move forward.. We loose some in bad suspension setups..

 

I completely agree with you on that!!!
