what mods would it take for a type-s to run like a mid 13 in the 1/4 mile n/a and w/o the 3.5 swap?

spdy0001

Not gonna happen.

You need either the 3.5 swap or FI to make those numbers

Wasn't Allmotor_2000 running 13's with all boltons?

spdy0001

Ok I stand corrected it appears that Allmotor_2000 has these numbers '03 CL-S 6spd (NA), 13.572 @ 102.65. I have no clue what all he did to hit those numbers though. Plus it will be harder for you if you have a 5AT tranny

custom made larger TB and ported IM i believe

It would be impossible with a 5AT. Even with full on slicks. Assuming you mean mid 13s = ~13.5

i heard port and polish does not do much... but ported throttle body and intake manifold might. anyone confirm this? not too many people are doing it so i dont know how good it can be.

I think you can run 12's NA on a 6-speed. The issue is traction. If you can get out of the hole properly (1.8 60-foot time) and have about 270whp, you can hit very low 13's. The 3.5L will give you torque, so on an 5AT you can get out of the hole pretty well.

The 13.5x run was on a relatively shitty launch even with drags on (barely made a 1.9x 60-foot). The clutch busted so the mph was not that high - see thread on clutch issues at that time.

Mods were:

i. Extrude-honed intake with a nearly 80mm inlet
ii. Custom throttle-body (oversize, billet unit)
iii.Fuel mods
iv.Short-radius CAI (like a short-ram, but its a CAI)
v. Lightened flywheel + clutch (Comptech)
vi.Some weight reduction (took off the exhaust completely, but that's about it)

allmotor - what fuel mods did you do? im running out of boltons and im contemplating whether or not to go 3.5L, i was thinking a walboro fuel pump and fuel reg, and ill be replacing my plugs with fresh ones, but on NA i figure there isnt much more needed than that in terms of fuel.

If I had ALL the bolt-ons and some slicks I could probably see some mid 13's, but they would come at the expense of some serious driveline abuse.

power3dfx

i dont think anyone here has ran a 13.8 or less in a 5at NA 3.2
if you have a 6 speed, then its doable but will take time. If your auto, dont even think about it!

Our Cl's weigh far too much to expect low 13's with normal aspiration and without some very severe abuse of the drive line. Even if you did get a good launch, like a 1.7 or 1.8 sixty foot time.
I have had my LT5 'vette on the strip dozens of times with a best of 12.66 @ 114.9. Now I have to tell you, that under 13 sec ET did not come without some
drastic means and luck: a perfect launch (for me, which was not below 1.9) and some top of the power band power shifting, ouch if you miss! . And that is with a motor putting out over 330rwhp and moving 3,500 lbs of plastic and metal and running drag slicks. In other words, flogging it.
The 114.9 trap speed indicates my motor is making decent hp but I would need far more torque to max in at lower rpms to get better et's. For most heavy cars, you need that low end torque to post the good et numbers....higher hp will get you some decent trap speeds but you first have to get all that weight moving from a dead stop.

Didn't Matt G run like a 13.2?

typeR

really?

typeR

opps i meant ...REALLY?

typeR

and my 13.306 at 106 was prior to the TB/upper lower intake ,and prior to the thermoblok,and spoon t stat

don't forget that we can remove our front and rear cross beams, VSA, and a few minor other things to rack in 50+ lbs of weight reduction. some light wheels would also help in weight reduction along with the whole rotating mass thing. and don't forget that headers eight less than stock headers, and i believe that goes for the rest of the exhaust but im not positive. also im pretty sure my comptech icebox altogether weighs less than my stock intake system (whatever it may be). and don't forget there are carbon fiber hoods and trunks available for our cars. with all that, you can lighten the CL up enough.

taking all of that into consideration... beef up the suspension, all the boltons, and i mean ALL boltons... i believe a mid 13 is VERY doable.

i know its a long shot, but if typeR ran a 13.3 with the 3.5L upgrade and that wasn't including ported throttle body/intake manifold, spacers, and thermostat... get a good launch, and why not?

like someone said, its not going to come easy, but it can be done without 3.5L, turbo, or supercharger.

typeR

and im planning a 12.9 or better with the above mentioned,also plan on adding test pipe comptech B pipe and maybe magnaflow cans

typeR - were you forced to go with the 6MT Icebox after removing the VSA or are there more gains to be seen by it than the one designed for the 5AT? i would think they provide the exact same gains, but i was just curious since i believe you are the only AT running the MT icebox.

typeR

I DONT KNOW IF ID SAY FORCED...the only difference between the two is the length of the tube from the throttle body...so yes i went with that on purpose because i wanted to eliminate the VSA
