im looking at http://store.summitracing.com/partde...5&autoview=sku
and was wondering it's a good choice and what are actual gains on it. i read that stock cobra's are around 8-10 psi and that the 2.8 pulley adds about 4-5 psi to that is that correct? and also im looking IRS braces is there any brands i should look into? sorry for the noob questions i come from a place with 2v's less then what i have now (mods are on my sig btw)

hmmmm.... did it come that way when you bought it??? with 434hp/451tq? chances are that your already have a pulley on there... do you have any pictures of the motor????

MAD SVT

as far as the IRS brace goes... I have the Steeda one, alot of people go with the billetflow, its about the same cost... i dont see much of a difference other than the colors.

And you definately want to get one if your pushing 450tq... especially if you plan on running drag radials or slicks in your future

MAD SVT

btw.... Nice car! =)

Save your money and wait for FPW's IRS cover. It's finned billet aluminum with cap studs and o-rings...it's quite impressive.

How much boost are you seeing now? FWIW, careful with "sure grip" pulleys like that, they have a tendency to chew up blower belts.

MAD SVT

ok you already have an aftermarket pulley, measure it next time you have a chance, looks like it may be 2.8 already... compare pics

thats my old setup

<<<< i fail so hard thus the name of the thread, its a 2.93 would i benefit much switching to a 2.8?

MAD SVT

maybe 8hp... 12 with a good tune.....

i'd do it cause that pulley looks like crap LOL sorry.

(btw you'll need a re-tune)

yeah pulley looks like ****. i should be at 10-11 psi right now correct?
