Welcome BTW
Well what tires are you running? What boost are making? Give a little better description of your setup.

i think you just scared him away... :bored: :-D
My bad lol im running 18lbs right now running 315 nitto 555rs 10.5 rear rims 3lb pulley stock headers wat else do u want to know man
All performance mods including drivetrain would help.Not all about power,boost and tire size.
I think he's asking what the guys with the 2.3's are runnin, not what he's gonna run. I could be wrong
Think he wants an idea of what it will run with what he currently has. And maybe what else he should upgrade?
yes everything is stock besides motor and blower have some irs upgrades n upgraded clutch, and flywheel....just trying to see what other fellow cobras are running
I'm curious to know what people are running as well in the 1/4 with a 2.3L with the supporting mods
look's like most 2.3 whipple cobra's around 600rwhp, run high 10's 10.7-11.2, at 129-134, tires, suspension, and driver are key factors, but that is what I have seen posted, I think with a solid axle and weight reduction you could get low 10's.
I'll let you know in a month.

With slicks there are guys running mid to low tens... It's all driver as long as your car doesn't break.
With a 2.3 Whipple, 4 lb lower, 3.0 upper, Spec 3 Plus clutch, level 5 hs, CAI, Afco H/E, and M/T 315-35-18s, my best time was a 10.89 at 124 mph at Bristol during a Fun Ford Weekend.
10.50s blower only, low 10s on the bottle.
Is there a particular reason you guys chose to you lower pulley's compared to just using a smaller upper pulley (ie 2.65/2.75) to achieve the same boost level? I know you'll get more torque with a lower, but I heard a lower is a whole lot more dangerous. Just asking.. Thanks..
Thats not a true statement. boost is boost pretty much, A lower helps prevent belt slippage. Your getting more power just from the more psi youll add by changing your lower crank pulley to a larger size(ie 2#,4# ect.) Lowers are more popular with smaller blowers and boltons. When you have ported heads and headers you loose boost. So if u have a 3 inch upper and stock lower it usually makes 17 psi on stock combo's. add the headers and ported heads and you might only see 14/15psi , so less power at the wheels. With headers/porting you cant just add a 2.75 if u want 23 psi it will never happen so thats why people do lower pullies. There is no issues with lowers and small blowers. It when you run 3.4 whipples ive seen issues with the crank snout breaking off . The larger the blower the more stress and power it takes to turn. If your goal is fast street car small blower 2.3 or 2.9 ftw, All out i say 3.4. A 3.4 can be used daily but i dont see you being able to really use it on crappy roads.
Less belt slip
i recently ran a 11.22 @ 127.53 in the quarter mile. should have been a 10 sec pass but i bounced off the rev limiter from 2nd to 3ed gear. it was driver error, my first pass off the trailer with the new combo and tires. i also didnt have a cage so i was booted the next run. i went an 11.30 @ 123 and broke the blower belt half way through the run.
11.49 and slower a cage is needed.... decisions decisions...

I'll give you a worst case scenario.
I went on 275 street tires, was a last minute thing, friends called and wanted me to come.
On 275's I did 11.8@125. You should expect a better time then that with a clean run.
That was with stock clutch as well.

Funny that's what I ran on my street tires. Good to see we are consistent.
I drove my car to the track 25 miles on a 85 degree day and went 11.17 at 126.5. Got booted for not having a cage.
The combo should be good for a easy 10 second pass.
