To be clear... It's not about how big it is...it's about how well it flows. IE: pressure drop across it. The KW intercooler doesn't seem to flow as well as the TTS piece...at least in our testing. Now it was only a 2psi difference but a difference none the less.

 

they should give about the same power about the same psi , event is its 10-15 whp less who care ?

 

True. We've seen that 1psi is worth approximately 10-12whp.

 

Well technicaly if all the pulleys are the same you should be seeing the same amount of power with no difference if your only changing the brackets.im sure if you replace the intercooler and piping as well itll increase the boost pressure because of efficiency.im seeing 16psi with my kw kit with 100mm blower pulley ap1

 

True!

 

Another thing to consider is using brake ducts for a track car. I have the KW kit and Wasp brake ducts in my car. The brake ducts work with the KW intercooler and piping but I doubt they would work with the TTS piping.

 

Not sure why you'd think that but first of all the piping is only on the passenger side (yes...both hot and cold sides route around the passenger side) and it's routed quite close to the frame rail.

 

The pictures of the TTS kit seem to show that the two pipes on the same side take up too much room to allow another 2.5 inch tube to be installed along with the TTS pipes. The KW kit with one pipe on each side is tight.

 

Oh wait...are you talking about where the brake ducting would go through the inside of the fender liner? ...yea...I guess that might be tight.

 

I am not sure I will have the patience to continue to post in this thread. Learn from other peoples mistakes. Both TTS equipped cars I have in my area (I managed the install on one, and looked at the other in person), both owners ended up having the charge piping redone.

Do not waste your time with buying the TTS charge piping and intercooler. If you do not have any experience with fabrication of intercooler piping or intercoolers, do not comment or speculate on what you think you could get away with. Financially, you are wasting your time.

Could you use the KW intercooler and piping? Yes.
Would you need to rework the hot side on the blower discharge outlet? Yes
Would a simple silicone hose extension work for this? Most likely not as the angles and distances away from one another do not match up
Would fabrication of the engine bay portion of the hot side charge piping need to be fabricated/welded/modified? YES

Keep in mind, this is all about flow, so having nice radius bends is critical to have optimum efficiency of the kit (more boost pressure = more HP!). The 90 degree bend on the KW kit blower output is hurting air flow and has a direct relation with potential power output.

A comment was made about how 10whp isnt a big deal. That is huge, do not underestimate the difference a single HP can make, do not forget that is actually close to 12 engine hp depending on the drivetrain loss percentage you use. 12 engine hp, that is equivalent to the gain normally seen from a Js header being installed on a car that is already making around 480 engine hp (405-420whp)
