I am toying with doing the 75mm throttle body and y pipe setup. Who has the best pricing on a setup like this?. I like the AP (Cayanne) throttle body/plenum setup and was thinking of pairing with a speedtech y pipe. Any other suggestions?

 

no go with IPD and speedtech

Not sure you gain much though without doing turbos.

Maybe look at the 68mm set up

I have a Vivid Racing Y pipe and 74mm IPD works well but I only bought it for use with future Turbo Mods gains are not huge without i dont think.

 

pics of my car and dyno sheets in shoot out more are in the garage if ur interested.

 

+1, OP... what other mods do you have?

 

Mods are umw stage 2a turbos, billet diverters, 997.2 gt2rs intercoolers, LWFW, clutch, gt2 clutch mod, evoms intake kit, AP intake box, europipe stage 2 exhaust. the ipd plenum I am not a big fan of and I would still need to get the throttle body as well.

 

I have one of these never installed (went different direction if your interested? $ 500.00 + shipping

Just for curiosity, what size are those 2a turbos? With your setup, I guess the bigger TB and plenum will help. I have 75mm plenum, TB, and Y-pipe; I got them when SharkWerks parted out their "Great White". The plenum was custom made by Turbo Mike and the Y-pipe was one of a kind custom made too.

 

I have mixed feelings about mine also, after pressure testing, and having that thing leak from about every connection, I would prefer a welded part instead of the threaded connectors. The leaks were not very substantial, but they were present, and I did my best to address them short of removing the plenum from the car.

If I go to a larger TB, I may go with the Agency Power setup, however, it appears as if the AP setup does not retain all three of the stock Y pipe mounting points, which I prefer, but may be able to live without.

I believe there was some data showing an improvement in spool and power with K24/18g's, need to re-read those threads.

 

I have a vivid y-pipe along with an AP plenum and cayenne throttle body I am selling. PM me if interested.

 

PM sent

 

HI,I have been thinking about that mod.for awhile also.....Now,I am waiting for Todd from Protomotive to finish up on a modified stock Y-pipe to match up to the 74mm TB with a modified IPD plenum TimNYC gave me(I sent to get thermal coated) to do a dyno comparison with....As soon as I get all the parts in,I will be off to the dyno.....

 

I assume you are going to dyno before the install also ?

 

Of course,back to back on the dyno,Thats the only right way.....Going to switch it out on the dyno...

 

HI,Just got my Modified stock Y-pipe, match up to the 74 mm TB, from Protomotive...It looks great...Have everything now,the thermal coated IPD plenum came in.....Now to call a dyno shop to let me do the back to back switch on there...Can not wait.....

 

I'd like to shift my torque curve around 400 RPMS to the left.
