Doug, What was the motor combo when you ran 8.50s?

I absolutely agree with this. I too am running a dual meth setup (100%).

Haven't had any cooling issues, I already have Dewitts rad and fans and it ran 190ish this summer, and at night it is in the low 180s. Id rather fix the problem then cover up the issue. Meth has a purpose, i would just rather spend 500 on an intercooler and not have to worry about it.

bp92gsr

So you are running the larger race intercooler or no?

ZincGT

I would assume not, just what ever they send in the kit.

bp92gsr

What power level are you at? It may be different for cars running over 1000rwhp.

Don't really understand this thread. It seems you got the answer from users and directly from ECS.
If it's not what you wanted to hear, than just ignore it and put a larger intercooler.

I'll bite. What's an Askhole?
Just want to avoid being one.....unless it's too late

Basically asking a question until they get the answer they want, regardless of all the better prior answers being closer to reality.

Sounds like my wife

So, basically the car is maxed out on boost at 14 psi making 921. Power curve starts falling off right around 5k rpm. JMS says there no indication of belt slip and IATs are right around 60 degrees WOT. They seem to think this base ECS intercooler is the limiting factor for efficiency and why the car wont build more boost. That was at 13* timing (low and safe) with E85 and 100% meth and he plans to ad a few more degrees later tomorrow for some added power. JMS is telling me they think the procharger race intercooler will be the key to reaching our power goals. I am likely not articulating this as well as it's being told to me over the phone however I think we are on the right path. Tomorrow they will be check the car for boost leaks and if they dont find anything, I will likely be ordering a larger intercooler.

What pulley and damper are on that thing ?

bp92gsr

2.75 upper and 10% OD IW balancer.

realcanuk

Makes great power for 14 lbs.

bp92gsr

Ty! We will be strapping on a procharger race intercooler soon to hopefully allow it to breathe to its full potential. Should make more boost and timing will be increased as well. Only at 13* right now.

realcanuk

I don't know how it compares but my standard A&A intercooler is good for over 1000 easily. I think you might have some other issue. Let us know how it goes. Curious myself.

NJ_phil

Would be interesting to do a little troubleshooting on this by putting a map sensor on the suction side of the blower to see what the curve looks like as boost builds.

I'm sure ECS has done this along with another sensor on the other side of the cooler to measure differential pressure across the intercooler...would be nice to see some data on that

GeneSch

Has anyone ever pulled the intercooler out and bypassed it for just one pull on the Dyno? I know you wouldn't want to do this on the street but for one pull before everything was heat soaked. This should tell you the restriction your getting. I don't think the intercoolers going to be as affective on the Dyno is it is on the street due to the volume of air. If you think the intercoolers to Small and restrictive you would find out really quick.
Then you'll be able to answer the question if $1000 is worth one or 2 pounds of boost.

95vettski

No way should the power curve be laying over at 5k and the timing is very low. Your combo should eclipse 1k with the provided intercooler...no upgraded needed.
Similar combos produce 20+ lbs of boost so I'm curious to see what you uncover.

schpenxel

Yeah, timing sounds really, really low but tuner should be able to figure that out. Usually when it's that low they pick up a ton of power when you start adding a few degrees.

I thought people had had issues with the procharger "race" intercooler really not flowing all that well? Maybe I just made that up.
