Here is something to look at. stock blower 14.7psi you are able to keep IAT's in check with bigger heat exchanger and maybe trunk tank.. keep in mind this is at probably a 65% efficiency level on the map.

Now the weistec blower setup is supposed to be more efficient than the factory blower At 14.7 psi I.E should be somewhere in the 72-75% efficiency range on the map which in turn should be a lot cooler IAT's than the stock blower at the same boost levels .

which leads me to the efficiency of the intercooler.
Does anybody know the pressure drop on the factory intercooler @14.7 psi ?
what about Weistec's? If the weistec intercooler is more restrictive it could change the the efficiency of the supercharger I.E. lets say @ 14.7 the intercooler as a pressure drop of 2-3psi that means your supercharger is no longer operating at 14.7 it is really operating @17.7 PSI but with the pressure drop it reads 14.7PSI on the gauge because the supercharger has to work that much harder.

Damn congrats Man.
Your car and the work is just plain sick

The factory intercooler is going to be signifigantly more restrictive than the Weistec one. The area the Weistec supercharger blows trough is more than 300% larger and less than half the thickness.

Soooo true. If I paid that money on a "production" kit then I would not be wanting to trouble shoot. I get things can arise as all cars are a little diff, just like some are fine with 82mm TB while some just keep having issues.

RBJ to me called it right, doing all this testing and sending things back to be checks just doesn't sound good. I do agree you need the testing results to get the tune right but this really seems outside the general "let me see how I'm performing with my new setup and see what kind of improvements I can make."

Side note: RBJ hurry up and get that TT setup done!!!

I agree, what's the pressure drop @xxx CFM and XX psi on the wiestec intercooler? cause the weistec is obviously flowing a lot more air.


I was more comparing it to .
If the factory stuff with a stock intercooler is sufficient up to a certain point. The weistec with a custom core should be plenty capable as the factory SC. Heck ,I dont know.

but i would like to see some hard data as I would like to purchase bigger charger.

why are the cars with the same boost levels as a stock SC having a problem with IAT's especially if it is an more efficient boost source?

Pretty difficult to ascertain the pressure drop since the whipple blows directly onto the core with Weistec's setup. For your question.. I don't have a definitive answer.

As the 63 series cars (156) use the same IC setup and they are not having heat issues like it seems the 55 is ?

More displacement+much better heads and cams=a lot less boost/heat.

It's coming brotha. Thanks!

Car likes more meth. I've become a meth junky. Maybe I'll change my ID to to RedMethJunky. (it's crack for SC'd heaters).

Congrats on the kit and thanks for doing all this research. Looking forward to your results.

Hotsoss

I believe he is selling the car.

MindBend

Here's a log from last SAT....note the AFR's and the IAT's dropping in 4th!
Yes selling. Went GT-R and wife is a bit restless!

Thanks for posting that up.

PACougar

Trade wifes and keep the cars

RedBullJnky

Can you post a data log in auto, letting the car shift on its own? Dyno?

MindBend

0-60: no problem
Cougar: that gets even more expensive than cars.
RedBull: What would those things accomplish?

RedBullJnky

My friend is trying to compare it with another car. And we race, so he wants to see WOT til redline. And to me it looks like your a little rich in a few spots.

MindBend

Gotcha...I can log some more (however you'd like) but the local dyno shop told me that they are booked 'til end of July.

RedBullJnky

Dont worry about the dyno. We know where the power would be. PMing.

chawkins2001

Pretty good log there and those IATS are damn nice. Would love to see it rev and shift on its own so we can see the iats, af and timing in the upper rpm range.

Thanks for sharing.

MindBend

Thanks...I've been careful and methodical to get it where I want it to be. When taking 'er to redline the temps and timing remains about the same. You can also see how the AFR's dip as it gets into the upper revs, which I think contributes to the cooling effect.

I am amazed and how linear the power-band is up top too--it pulls as hard at 150 as it does at 50. This is where the Weistec really shows itself -- in the mid/top-end: it just turns it on, and keeps pulling like a freight train. For me, it places the power right where I want it...third gear is EVIL. Thankfully, that P030 LSD really does it's job and hooks it up too. (I think even more-so than the Quaife in my previous car).

The fact that it's super-smooth, and a heavy car, it's deceptive feeling until you look at the speedo.

Should have put it on the dyno when you were down here and Weistec was trying to get my car to start
