2003 Cobra

[aldeezy87]

Hello all, I just recently bought an 03 Cobra about a week ago so I am new to this. The car only has 8,700 miles and the prev owner upgraded the supercharger pulley, BBK CAI, has a short throw shifter, and tuned on 91 octane, supposedly makes 500 HP...is there any other mods I would need starting off? I see alot of Cobras that get lowered, which springs are best for that? Thanks for any replies.

500hp might be a stretch. I'd look into sub frame connectors before springs. Unless it already has them.

Best is subjective. I prefer H&R springs personally. I had the race springs and I liked them better than the Eibachs I've had on previous cars. And now I'm on coilovers and prefer them over H&R's.

500 is stretch for sure, especially on 91. Is it possibly ported with a lower pulley too? I did cut stock springs on mine. No complaints.

Vert or coupe? Nice find with low miles.

Thank you all for replying, I'm not sure about ported, will just get it on a dyno some day and see lol

Hmmm, I remember that white vert in his showroom.

Congratulations on finding such a low mileage '03 Cobra. Based on your avatar, it's Oxford White. Nice!

Yeah, unless the Eaton is ported, you're not going to see 500whp on 91 octane. Likely not on 93 octane, as well. You should try to find out what size upper pulley you have, whether or not you have a larger lower pulley, and whether or not the blower is ported. For porting verification, depending on who did the port you might see a tag on the blower.

Your Cobra produces 436 horsepower to the wheels.

Closest to the actual number wins

I'll be. I think it is the same one. It's silver, not white.

Customer had a dyno that it put down 483rwhp or something like that.

Silver

Must be a ported blower.

Correct, a black 2009 GT500 with a built 5.6L with 845rwhp.

 

[13COBRA]

If it were mine... I'd lower it, pull the tint off the windshield and drive the hell out of it.

 

[robvas]

I'd add a Whipple or VMP!

Wait, do you work at Chuck Anderson Ford in Missouri? This is where I found it

Yes, I'm the General Manager. We didn't meet when you picked it up, I don't work Saturdays.

 

[aldeezy87]

yeah I definitely wanna lower it and that tint bar on the windshield is too wide!
