what will my cobra run in 1/4 mile?

90 notch · August 3rd, 2011, 04:05 PM

I got a 90 notchback 5 speed with cobra heads and intake ported for my 75mm throttle body. I have a bbk cold air intake and underdrive pulley kit including a smog delete. Also mac headers to dual 2.5 inch exhaust. Around 160k miles on motor but runs strong. I'm really interested as to what other readers have run with similar setups. My trans needs a rebuild so I have to wait for next year. Future involves a cam (still deciding), 24# injectors, 76mm maf, and 1.7 rrs. Help?lol

What Cobra?????

nolife · August 3rd, 2011, 08:35 PM

What gears? My wild a$$ guess, 14.35 at 95

HMERacing · August 3rd, 2011, 10:21 PM

14.68 @ 127 or so. It will MPH like a mofo with that setup... I am gonna say it will be a handfull out of the hole though.

gears will tell the story. what gears are in your "cobra"

90 notch · August 4th, 2011, 09:11 AM

I'm literal on the ''cobra'' thing. It's just to show the intake and heads. Basically same motor as a 93 cobra. Not exact but close. It's stock 3.08 I believe. I'm not sure if I wana upgrade the gears first or jus throw some cheater slicks on the back. The car stock runs 14.8

127???? I'm thinking more like maybe 100-105

ReverendDexter · August 4th, 2011, 03:09 PM

Yeah, I wouldn't call it a Cobra. You may as well try to justify calling it a "GT40" because they're called GT40 heads/intake.

I'd guess mid-14s in the mid-90s.

StangBanger302 · August 4th, 2011, 07:09 PM

With stock gears, stock cam and slicks, I'd say a 13.5 @103 ish. Bone stock cars with a GOOD driver on street tires should run low 14s or high 13s.

90 notch · August 4th, 2011, 07:11 PM

yea true. I think it would do better than 14.6. Now I'm not too smart about the stangs yet but if that's what it runs stock then I'm hoping for better. My trans am ran 14.9 and the mustang passes it up easy. Experiment between my buddy and I.

StangBanger302 · August 4th, 2011, 07:24 PM

If you can drive and shift well, it will run a mid 13 on slicks.

91sleeper · August 4th, 2011, 07:36 PM

if on slicks becareful not to choke it down on the line

JBIGBOOTSY · August 5th, 2011, 12:40 AM

14.5-13.2 depending on all kinds of stuff. Mainly the driver.

90 notch · August 6th, 2011, 04:24 PM

I'm pretty sure I'm a good driver. Not puttin myself up there but I can run it pretty well

Chris951 · August 7th, 2011, 12:44 AM

I'm gonna say 13.8 @ 101

69fastback · August 7th, 2011, 09:02 AM

Lol....everyone is a good driver. Just ask.
