The throttle body flange is in the exact same place between this manifold and the OEM manifold. So yes, I see it working with everything else that fits the stock manifold.

How far would you have to cool the inlet charge to make a noticable bump in power? I dont want to do the math right now

Significantly cooler. It's a much bigger deal when forced induced as the possibility is there to get the temps down. With N/A, you'll always be a little over ambient.

A good rule of thumb, every 10 degree F, you gain or lose ~1% horsepower.

So whats to stop me from spraying something much colder over my intercooler other than water? Has anyone tried that yet? (Im assuming they have, but purely speaking of street terms, not race terms)

There are alcohol spray systems for intercoolers. Alcohol evaporates more quickly than water, which pulls more heat from the intercooler. I don't know if anyone's done it for this chassis yet though.

Hey @NotEric6....i found your next project.

Nitrous/propane spray bars for I/C. Not practical IMO but already done

Why not just do water/meth injection?

It's retarded if one has access to E85.
If not, I still wouldn't run it unless I have to.

[cdrazic93]

Not to mention it makes tuning that much more complicated.

If you guys want to start a thread related to cooling the intake charge, I will happily weigh in my thoughts in that thread. I have experience modifying and calibrating on my 500rwhp MR2 Turbo. I have used pump alone, e85 alone, pump with water, pump with meth, and E85 with meth.

Trying to keep this one dedicated to the intake manifold and construction of it .

Thanks guys,
Eric

My bad Eric. So in your opinion, how badly is the stock manifold preventing airflow? I guess another way to word it would be how much room for improvement was there?

All good! Please, start another thread and I'll weigh in with my opinions and experiences. Just don't want to derail this thread too much.

Hard question to answer. The stock design is unique. Ours is also unique. We believe it will make power but no idea how much. We're looking forward to the dyno as well.

I'm really not liking the math here.
Stock=unique.
Velox=unique.
∴ Velox=stock.
