P&P TB and Plenum

Willy Mo · November 24th, 2010, 01:58 PM

Is there a write up on the proper way to P&P a cobra throttlebody and plenum? I have searched and come up with nothing.

SWEET2KSTANG · November 24th, 2010, 02:07 PM

well, you wont find anything on that since the cobra's dont have a plenum. the t/b, not sure if there is an actuall write up for that.

Willy Mo · November 24th, 2010, 03:34 PM

terminators do have a plenum, between the Tb and the blower. I know I could just take teh dremel to them but i would like to know if there are certian things to watch out for like the IAC port, the IAC mounting knobs, ect.

SWEET2KSTANG · November 24th, 2010, 03:48 PM

oh, for some reason i was thinking you were looking into the 99-01 cobra's only. i can do a write up, but it will probably be kind of vague unless i took more pics than i thought. are you welding it up or just porting whats there?

Willy Mo · November 24th, 2010, 03:51 PM

may do both. I have a small build underway (making a new sheetmetal intake plenum for my kenne bell) and am debating using the 03/04 plenum, or just make it all out of sheet metal and just use an 03/03 style TB. I am porting the TB for sure. I may just sell the plenums.

But a write up on both porting and welding up the plenum would be nice.

SWEET2KSTANG · November 24th, 2010, 03:55 PM

i tig my plenum's up, so thats what i have as far as finished pics are. if you have time and ability to tig, you can modify the stock plenum to get fairly close to accufab or dragon. the short side benefits from a little tig and work no matter if its stock or aftermarket. depending on how much boost you are going to push, then the stock t/b will be next choking point.

Willy Mo · November 24th, 2010, 03:59 PM

at teh moment Im peaking at 11lbs. but hoping the new plenum will free up a little bit. Im thinking I am just gonna delete the plenum and make it all sheet metal. Would make it easier and have less parts. BUt still want to port the TB.

SWEET2KSTANG · November 24th, 2010, 04:01 PM

i dont have any pics of a stock plenum, just pics of tig and finished product. as for the t/b, i only have finished pics of them as well.

SWEET2KSTANG · November 24th, 2010, 04:24 PM

tig'd plenum

this is about as far as you can go before you bust thru

and

Willy Mo · November 24th, 2010, 04:38 PM

Thanks for the pics. That helps. what kind of bits do you use? the last tike i ported a cylinder head my bits grenaded.

SWEET2KSTANG · November 24th, 2010, 04:46 PM

i have a decent amount of money wrapped up in my porting stuff. i have a small cabinet that houses my porting grinders (still go more grinders to buy), cartridge rolls, mandrels, carbide bits, head stand, etc. i do quiet a bit of porting, so i constantly buying something to make porting easier on myself.

Willy Mo · November 25th, 2010, 03:02 PM

Yeah I would like to do more porting, but I dot have all of the right tools.

cc250r · November 25th, 2010, 08:42 PM

what did u tig weld? were there holes there or something?

Willy Mo · November 26th, 2010, 03:00 PM

If you look through a stock plenum. You can see dips in the casting that partrude into the inside of the plenum. You fill the dips on the outside by tig welding them. Then you can remove the restriction from the inside.

Everett · November 26th, 2010, 03:06 PM

i have read alot about gasket matching to remove material for more volume and better flow...i have started on my gt but have found i should buy stock in carbide grinding bits cause you can time the life of them on a stopwatch

SWEET2KSTANG · November 27th, 2010, 12:12 AM

you must have either cheap bits or just hardened bits. i dont have many go dull very often, but i also spend a decent amount of money on mine.

Willy Mo · November 27th, 2010, 03:54 PM

sweet where do you buy your bits from?

SWEET2KSTANG · November 28th, 2010, 12:08 AM
