well I had it on the dyno and they tried to tune it but it just wasnt boosting past 6k, but at that rate they said 200whp before 6k, so im not sure. The tuner pretty much gave me a map thats more on the richer side so i could try to fix the problem and come back. I still am running the stock wastegate actuator, cause I dont know what other actuator I could possibly get? Thanks, any info is great help.

Could be a number of issues . You should start a new thread and ask for help . Include photos of your setup and to hurry things up do diagrams of how all the vacuum lines are hooked up .

Brian (from BNR) is working on an upgrade to the stock actuator but your issue sounds like something else as well .

has anyone had any updates to this topic?

Has anyone tried that CX intercooler? Is there still not a better replacement for the greddy one?

So IIRC, too small of an inter cooler and you get heat soak, too large and you get boost spikes right?

it seems pressure drop and engine temps(blocking rad) was the main concern with going bigger or taller, im wondering if staying within the same dimensions as the greddy but with a thicker core will net any significant benefits...are you going to run the stock greddy 9k?

Honestly I am considering a water-air inline intercooler like this. this guy was making 15lb of boost with it before heat soak was a problem and he needed a larger one.

To clarify :
For power levels below 300whp the stock IC is fine

Over that and there are benefits :Ie reduced charge temps and reduced pressure drop

As well as drawbacks : slower response and if you block the radiator , reduced engine cooling capacity .

It's a balancing act between power level/air cooling/response and engine cooling .

That's my problem, My single Fluidyne oil cooler works great and there is really no place to put it other than moving it back and putting the Greddy IC in front of it. I don't want to do that and block the radiator even more. I plan on using a stock oil cooler as a secondary radiator but I'm not sure if that would be enough to make up for blocking the radiator even more.

So, I am thinking of trying this air/water intercooler just to see if it will work. If not, I can always put the Greddy on.

Thats an interesting set-up, like what chris from esmeril was running, Im following your build so this would be a nice way to set your 8 apart from the rest. I just need a new one since the intercooler in the kit im getting looks pretty beat up.

Well if it works out, I will sell you mine cheap, it's in perfect condition. I did read some though about improperly cleaning intercoolers so if you get a used one clean it the right way or have it done professionally.

Tough to read but informative

What about laying the fluidyne on its side on top of the plastic undertray ? The Pettit guys have been putting a 2nd radiator in that position with some succes .

I thought about that but it is pretty thick. I am going to pull everything apart this weekend and do some real test fitting. What did you use to clean out your oil cooler before using it as a secondary rad?

Brettus

iTrader: (2)

hmmmm - that was like 3 years ago . Mineral spirits should do the trick .

Sites under constuction but yeah il definitely be looking into that...shoot me a pm whenever you are ready to part with the IC Didnt you just get an aluminum rad?shouldnt need a secondary rad or are you planning on running the oil cooler directly below the ic?

Link works for me

Yes, I did, but any inter cooler I use will have to go in the path of the radiator. Plus I have the cooler laying around and two empty spots where the stock oil coolers were so why not when temps on the track can reach 120F easy. If over cooling ever becomes an issue (highly doubtful in south Texas) I will easily be able to bypass.

Just fitted this slightly smaller IC than the first one i tried - no cooling issues this time (cross fingers)

600x260x75 (first try was 600x300x75)

Is that the Greddy one that comes with the kit?

Brettus

iTrader: (2)

The top one is the stock Greddy . I just fitted the bottom one .


Managed to get it high enough up so the bottom is in same spot as I had the Greddy - so still plenty of airflow underneath .

Sweet, I thought the top one looked like the Greddy but I have been looking at so many lately they all look the same now

RXPLODE

hey brettus i got that same filter, are you getting reduced airflow with it? i did a before and after check and i saw a 20 g/s loss with that filter.

RotaryMachineRx

^ I see 10-15 g/s less depending on the weather sometimes....

Brettus

iTrader: (2)

Have not tried any other - what did you compare it with ?

Brettus

iTrader: (2)

This is the approximate gains from the exercise .....

Nice. What do you think that equates too in performance?
