Hello all, My name is Patrick and Im new to these forums. Before now my life has revolved around 944 turbo's but now I'm starting to take interest in another engineering marvel, the S2000!

Ok first off I would like to say that I am in no way working for this company. many people in the 944 community have used this and it works amazingly and you can you them as your charge pipes. I plan on buying an Ap1 soon and building a turbo kit to incorporate these.

I personally think they are pretty badass and a great way to save space which seems to be somewhat needed on the s2000.

anyways, let me know what you think.

 

Looks cool Patrick. Do you have any data or links on this like charge temp drop or flow rate?

I have look at these thing on and off for a couple of years.

The theory is sound however I not seen any hard technical facts on the THP.

Even called them a couple of time to see of the shop can pick up a couple of them and do some independent testing.

It would be very easy to replace the PWR intercooler like what SOT using on there roots setup with 2x 6

 

Well so far Lindsey Racing hasn't released any hard facts as of yet. The reason behind this is because shortly after introducing the THP they moved to a different shop and bought a dyno so they are getting everything set up before they go into testing.

Hausbrauen has done some testing and found a 90 degree temperature drop on a car running 18psi when they mounted it right after the turbo and before an air to air intercooler. I also read on a porsche forum that a guy found a 50 degree temperature drop using only the THP.

That was also using coolant from the cars radiator, imagine if you could setup an independent cooling system for the THP. Another cool thing about having an independent system is that you can use whatever you want for cooling. You could even use R12 as long as you don't burn it, then it becomes mustard gas and you would literally kill your competition.

 

 

hummm 50 deg drop on the first THP using the cold side of the stock radiator. That water has go to be in the 120deg range so that

 

Givens:
3 cores
50% efficiency on each core
300deg F turbo outlet temps
90deg F cooling fluid (each core gets a independent input of the cooling fluid)


Turbo outlet temp of 300def F is really high but trying to prove a point and the inlet temps do not contribute to total efficiency numbers.

First core will remove 105 deg F of energy
Second core will remove52.5 deg F of energy
Third will remove 26.25 deg F of energy


IATs will be 116.25 deg F

That

 

You are a very smart man lol.

 

gee at least we know who went to college and payed attention in all those math classes.

You lost me with the ah hell im just lost in general.

 

LOL
Thanks for the complements

You should see the program I have made that can generate a base map for injector pulse and base timing based on some known factors of a piston motor

Displacement
Mass flow (NA or FI)
VE of the motor Vs RPM
BSFC Vs RPM
Desired A/F Vs RPM
IAT VS RPM
Conditions (IAT,A/F, EGT and spark timing conditions that cause the onset of inaudible knock VS RPM and load)

Just to name a few things that must be programmed in.


The results are usually within about 5-7% on the safe side of where they should actually be to extract the most power possible.
Some other factors that would improve the formulas would be piston/head design factors, thermal cooling factors of the combustion chamber that should be included in the equations to truly calculate the burn properties of the flame front; just to name a few things that the manufactures are just not going to give a random person.

Sorry guys I will not giving out this program it is something I did for my own amusement.
In the end, what the program accomplishes can be done on a loaded dyno with enough time. The program just cuts down on the time you need to spend on the dyno so you can spend more time on the track.


Yes I am a Gear Head S2000 nut how can you tell.


OK back on topic
