Terror, thanks for the positive response!

We remain confident that these manifolds will make power competitive with anything outside a full-on race build...


This casting is based on the fabricated 304 SS manifolds from my original side mount TT system.

Let's take a look at this dyno graph and notice how the slope of the HP line is positive and still climbing especially when compared to other builds of the day that had fabricated tubular headers with merge collectors. The first graph is from a Gen II motor with rods/pistons/stryker street heads, 708 hydraulic cam/lifters with a 66mm cast compressor wheel turbo at 22 psi.



Here is a graph from a higher revving, fabricated tubular manifold with merge collector, big turbo build from a prominent Viper tuner. Engine is an Exotic engine build with GTS-R block, Stryker race heads, solid cam/lifters and a 74mm turbo (possibly billet) at 23 psi.



If you look at these two builds up to 6000 RPM, there is virtually no difference between them.

Latest on the build... They are mocking up the turbo's and as you can see the manifold fit's fantasic, plenty of clearance! CPE's been working around the clock on this system. Looking to have it installed/running by Feb so I can have it ready for March to drag a few cars up and down the track in TX2K.

Here's some latest pics for the mockup.

Looks good man!! Are the manifolds going to be cut so the plugs can be changed? Maybe it's the angle of the pictures..

Thanks!! Yeah they are cutting the flanges so the plugs/boots will have penty of clearance. The pictured manifolds are uncut and are just for mocking up the piping and turbo placement.

Yeah, manifolds were made for all generations, so they have to be trimmed to the particular generation onto which they are being installed. As was mentioned, this is just for mocking up the piping.

Not running a heat exchanger on my setup, just the water/air intercooler.

Me and Master P were talking about it a while back, I think were were going to do some testing with the setup as is and add one later on if needed. I really think it won't be necessary for my setup though. What's your thoughts on it?

since we both are going to use air to water here's what I gathered. The key is to size your reservoir properly according to pump size On average the most turbo cars on the street will see is around 20 Seconds of WOT at one time. That's 33% of a minute If your circulation pump moves 5 gal. per/min. Your reservoir should be minimum of 1.65 gal. (I'd shoot for 2 gallon) I do like your size by the way. By sizing it this way when you are at WOT there's always cool water running through the intercooler instead of trying to rely directly on the*radiator to transfer the heat out..

Since Eugene lives in New Mexico, we are first going to try no exchanger and to run the pump for the water only when in boost. This has worked well for Michael Brito in the Florida heat for some 20,000 miles. If this is not sufficient, we will add an exchanger later!


The heat exchanger will be 1" thick with a ton of frontal area. This wil not block much air to the front of the car for the radiator, but nothing will be the best for the coolant and the hot climate!

Turan, one other big consideration is sizing the pump's flow to the HP so it can circulate the water through the IC core quenching the heat build up.

Like I have previously stated, the pump will only be running when the car is in boost.

So for a given volume of water in the tank, the IC core and the lines, there will be a certain amount of water in the system available to absorb the heat generated by the FI power.

The other consideration is the car's cooling system. After several 1000+ RWHP highway pulls, I can guarantee you the oil and coolant will be very hot.

So all these things must be considered to determine how many pulls the car can make while maintaining safe coolant and oil temps as well as cool air intake temps!
