65mm

99blkcobra · July 6th, 2008, 05:18 PM

is a 65 mm to big for a cobra, i was looking at a 65 mm bbk, thats ported?

DeMello · July 6th, 2008, 05:20 PM

i THINK 65 is stock

im pretty sure you at least want at least 70mm, and a 75 would probalby be even better since its a 4v

99blkcobra · July 6th, 2008, 05:23 PM

stock is 57, the biggest ive seen is 65mm

Is the throttle body really a choke point on that engine?

HMUSN · July 6th, 2008, 05:29 PM

65mm is ok for your car.

99blkcobra · July 6th, 2008, 05:30 PM

would a ported bbk still stick, i heard i could open the throttle body if its sticky and that will make it unsticky

HMUSN · July 6th, 2008, 05:33 PM

I would go with an ACCUFAB product before I would touch bbk's stuff.

Doc8224 · July 6th, 2008, 09:48 PM

The TB is not a big choke point. Don't think you need a twin 65mm or a big mouth unless you are going boost. twin 62 would be best for N/A

Mach Boy · July 7th, 2008, 02:23 AM

+1 and I would be hesitant on even buying an aftermarket throttle body as so many people have said that they have had problems with them. More have had problems with the BBK than the Accufab. If you do decide to switch TBs you won't see probably more than 2-3rwhp on a lightly modified Cobra/Mach. It's simply not worth the money and hassle unless you're going big power.

DeMello - Cobras and Machs have a different throttle body than your GT does. Learn more about these cars before you start spitting out suggestions and someone buys a $300 part only to find out it won't fit.

+1 A good P&P'd stock one will get you high single digits and going aftermarkt beyond that might get you 1-3 at the very peak

BizCutt · July 7th, 2008, 06:12 AM

Dont get the BBK......BBK SUCKS ACE!!!!!!!!!!!!!!! dont waste your money on a throttle body if your mods are what is in your sig....get something else for the money...youll notice jack with the 3bills for the TB............But Whatever You Do...Never Buy The BBK Throttle Body............BBK SUCKS ACE!!!!!!!!!

Doc8224 · July 7th, 2008, 06:14 AM

How about the BBk? Are they nice

99blkcobra · July 7th, 2008, 02:19 PM

im just trying to get all the bolt ons for next year, when i turn 18 im going with heads and cams, all engine, and im trying to wait on long tube because my car has never had the clutch changed so i dont want to do long tubes then clutch

other than that i want suspension but dont know much about it, havent decide wether to stay with the irs or go over to solid axle

Mach Boy · July 7th, 2008, 02:38 PM

Just beef up the IRS. Everyone here says oh swap it out, but if this is your DD you can't beat IRS. Just get an IRS brace. There are plenty of suspension mods to do and if LTs are going on you might look into a new K-member to help it fit. Take the $350 you would spend on the TB and beef up the suspension or get a new K-member.

99blkcobra · July 7th, 2008, 03:12 PM

ill look in to it, but im going to get the water pump instead of the tb im looking for another car so it wont be my dd anymore

If its the single blade big oval then its a shit load bigger than 65mm. They flow like 1700cfm. they are every bit of 140+mm

I guess so , I know the 1700cfm is right but couldnt tell you different about the 140mm+, but they describe and sell it as 65mm big oval and that is what I have.

I have 480 to the rear and 512 torque. I dyno'ed a little higher than most pulled cobras and I bet because a lot of people don't switch the TB.
