Here is what I'm going with my intercooler setup.

Everything is mock-up in the photo but will probably end up something along these lines.

 

Awesome man keep us updated! Im considering a vmount with my 20b but im not convinced of its ability to keep IAT down compared to a front mount quite yet. Im glad to see someone else is willing to be the guinea pig. Are you going to keep the factory hood?

 

I ran this setup on a T88/13B and the IAT was nothing out of the normal. The stock hood still fits just fine... got to keep my accessories in the stock location(s).

It'll be a while before I'm logging any data however.

 

V-mount on the 20b works really well. Air temps on a customers car we built were in the 88 degree range on a 86 degree day while cruising around. Under loads for extended periods it would get up to 94 degrees. Which was extremely good in my opinion. Water temps are the best benefit however, as they stayed at 86-89 Celsius the whole time. The hood on this car was vented, which really needs to be used for the full effect.

 

hwnd Have you started on the ducting yet? any pics?

 

piping & airflow are secrets! involves carbon graphite and wiggins/adel clamps :-)

 

uggh. come one secrets dont make friends lol! good luck with the build man

 

Decided to dry-fit the bumper (without the inner structure support)..







all in all, not bad.

 

not bad at all man but the pics would be better if they showed some ducting lol

 

I'm still learning about laying up graphite. This will be very interesting when I get to that point. I've still got miles of mil-spec cable to run throughout the car.


My main goal though is to log temps before & after the duct work.

 

not trying to be critical but why is the before and after temps something that needs to be monitored. obviously AIT are important but why are before and after intercooler so important. Or am I misunderstanding?

 

It'll let me know how well it is or isn't working. If "ducting" works then I'll know the next revision will need careful attention. Same idea with the oil coolers & ducting

I surely dont have any number / target goals but I can surely attempt to beat stock setup and get the intercooler to be as effective as possible.

 

Looks good man, What kinda power do you plan on making? will this be another 600+hp 20b monter?

 

I dont have a HP target in mind. Instead I've tried to think along the lines of using parts that fit with one another.

For example:
Quality turbo that will flow xxxx CFM @ 1.7 bar
(This is based on some theoretical CFM modeling of my port design)

Knowing roughly what I want out of the turbo, I'll be able to piece together fueling requirements for supporting that and having x% of room.. yada yada.

Another thought I have is I dont really want an undriveable car. I want something that'll idle below 1k revs. So a proper flywheel, tuning, etc come into play.
Sorry I can't give a "hell yeah I've got a GT55R turbo - mad power!!" type answer but that isn't really my goal (to obtain XYZ hp). The closet I can give you to that is I am using a GT47r on the engine.

The manifold design will have to change a little bit but like the mock up photos (showing a junk T66 or T72) it will sit pretty low. Now only if I could find a way to hit a 5gal oil tank in the car! :-)

 

since it's not a full-fledged racecar, this is exactly what you should focus on and spend your time trying to achieve. i still love my cars a bit on the obnoxious side, but i've definitely learned to appreciate (and admire) a car that one can simply drive.
there's nothing to be sorry about - at least, not in my eyes. you're doing an awesome job. i await its completion.
