plenum
 

i want to replace the oem T plenum since its blown,do i go with IPD 74mm +TB ?
Thanks

if your cranking out decent power, you can go with the TB and IPD plenum.

Good choice. You will like it.

Blown?

Do a search and you will see info on this..I just did a test on this on my car the other day , there is a thread..
Results may vary due to mods...:)

i purchased the 74mm plenum + TB from IPD,i hope they will add some hp.

+1 how?

the valve on the top of the plenum is blown

Can you get just that valve or do you have to do the whole assembly?

Generally the feedback on the new plenum is that it won't really give you any benefit unless you're up around 600 whp/wtq.

porsche sell the whole assembly.my gt2 has all bolt on parts,i think i am arround 800whp on high boost

Congrats bro :)
Can't wait for winter time :)

Do you have any 60-130 times?

i ran 5.7x on 1.65 bar when it was pure switzer(A28 and stock intake)but since i upgrade my turbos to A30/76 and proto mafless tune with the proto fender intake i didnt try it but i feel the car on 1.2bar much much faster than before on 1.5bar.

OK thanks. I would be interested in the new 60-130 with the upgrades.

If you are replacing the plenum you might want to think about doing the 997 intake manifolds as well. I believe this is what Protomotive, Switzer, etc are doing with all of their high power builds. I also have a fresh set for sale in the classifieds if you are interested.
