Fast Intentions Stage 2 TT build by MA-Motorsports.

Well, that is my story. Like it or not I am the one responsible for the car. I won't be using SOHO ever again. Needless to say that new SOHO intercooler did nothing. The IAT's were about the same. They actually got to 168 degs at Pocono. The AFR's were 13.8. Lean big time. That intercooler does not work. It is way too small. I did miss 5th gear at Pocono. Revved the dang thing to 91xx rpms. Marks valvetrain mods held like a champ. I have dual valve springs on intake and exhaust since I have 1mm larger valves. I don't recommend doing that. I had never ever done that before.

So, what got my headgasket? Hard to say, I have no data. From pulling the engine apart, it is not conclusive. What did happen is this. At 28psi of boost it made 996whp. At 29psi of boost it made 1004whp. The turbine side was done on my turbos. For it to stop making power like that I hit a drive pressure (E MAP) limit. The other thing was high IAT's. You don't need to go over 150 deg. That is the danger zone. Mine was well above that. I would have made more power at lower boost levels with the correct intercooler setup. The tuner didn't know where to stop trying to make power. Nick at SOHO is just as guilty as what he claimed about someone else during the latest fiasco.

Glad you are sharing your recounts. I hate spending the proper $ and time, but still not getting the proper product. Hopefully this time is the charm. Good luck sir.

I have been holding this in for quite some time. I just want to be done with it and move forward. I would have switched over to a VR38 but I am too far down this rabbit hole. I might as well figure it out or get humbled again.

3rd mod that has never been done before is in the works. 2nd was done the other day. You will just have to wait and see what these are later. That's if MA posts them.

Spooler · 03-22-2023, 09:35 AM

Mod #3 is done. Moving on.

Can I suggest that you look to a PWR intercooler. If you have a design, they can make you one.

I sponsored a PWR radiator for a race 370Z as well (intended to cool 600hp but not 1000 so might be a bit under-spec'd). Happy if you email me (I think you have my email address - if not, PM me) and I'll provide details.

PWR work with F1 on cooling systems (intercoolers, battery and ICE cooling as well)

We are kicking around ideas now. I will let you know.

Made the decision to custom build a large one. It will be less stressful this way so I know it fits. May have to break out the Sawzall. LOL

New Intercooler is done. Moving on along.

Spooler · 04-06-2023, 04:42 PM

It's a big un. 28x12x4.5 Bell core.

Intercooler pipes are done and they were a challenge to get to fit properly.
