How can a dyno accuratly measure the HP of turbo car with a intercooler?

How does one simulate the air flow over/thru the intercooler on a wheel dyno? Especailly a FMIC.

Aint no way a fan or some **** is going to do it, so how do you tune the car and calculate hp??

thats always a problem, all you can really hope for is that the air temps stay down

or you can buy your own wideband like me and do a 4th gear pull and datalog the haltech and wideband and then pull over and read the maps and tune it https://www.nopistons.com/forums/pub...DIR#>/wink.png

so really if you dyno lets say 300 hp, you probably are making a bit more underway



Ill read that link tomoroww when I have more time, thanks Mike

making more power off the dyno is not an absolute, you could have a misdesigned intake that didn't work at high speeds.

your mixtures will also be slightly different on and off the dyno, so its best to be a little rich on the dyno.

tuning the car is one of those, the more you learn the less you know things, it can be a puzzle

Big fan or something in front of the car blowing cool air in on it? I saw one once, looked like the things that inflated the bouncy palace things.

You still havent gotten your car running 100% yet right?

haha, what tipped you off? i need to go back to the dyno and retune it, we are kinda wiating for the outside temps to drop



mike

I remember a while back you got 200hp or something, then not hearing anything more about it.

I was hoping for some better news.

i havent driven the car in a while, its got no heater and no wipers
