It would be nice to know at what power level this car was at prior to the newer intercoolers. That would at least give some idea as to what level of power these things maxxed out. I too would be interested in knowing who made the intercoolers that were removed - I'm puzzled as to why this is some secret. If there's a product out there that's not built well throw the flag! More back to back kinds of tests would sure be nice.

As for heatsoak on the dyno - a little rubbing alcohol mixed in with some water sprayed onto the intercooler with a mister will help cool it FAST between runs

 

It feels good that I made the right decision going with EVOMs ICs.

 

i just dont wanna mention any name (just my respect to them) hope u understand.

 

oh yeah u certainly did congrats....

 

no it wasnt all 30 pulls wasnt on the same ic. Todd wanted to make that it was perfect...we also tested a few additional mods

 

Dude you finally get a tune dialed in for that meth kit?

 

for sure bro

 

Wow.
How hard is it to swap out the I/C units. I should have considered doing this when I upgraded to Kevin's Z/C turbos.

 

It is not surprising that inadequate IC's lose power on the top end. Especially as the ambient temperatures go up above 70 degrees.

Back when we were performing multiple dyno runs, the motor made it's peak power at 7500 rpm's. This was back when we were running stock internals.

I do not know what the efficiency rating of the EVO units are, however they appear to be nice. Did the EVO units you install have the optional heat dispersant coating? If not they can be made better yet.

 

With my stock IC's and Meth, the hottest IAT I saw at the Texas Mile was 109deg. I wonder how much better I could get?

 

New I/C and maybe you have a 200 mph car


(Do you have stock Intercoolers ?)

 

The only conclusion that can be drawn from this data is that Evoms is better than the ones you had. Period.

And since we don't know what you had for some reason, readers have nothing for comparison.

The whole "what is the metric for assessing intercoolers" and "Why are there no published technical specs for intercoolers" continues...

It's a safe bet that the intercoolers he had were probably better than stock. However since we also do not know power level the data is again useless. 40+HP gain on a car that had been making 900HP is a WAY different flow requirement than on a car that had been making 500HP. Obviously the previous intercoolers were choking things but at what level they run out of flow and who made them is a complete mystery. The take away here is that yes intercoolers can be restrictive so pay attention to them at some point.... Not enough info to learn anything else at this point.

P.S. We did learn the Blown 6 intercoolers are pretty restrictive though - thanks!

 

I was also presuming the OP has something better than stock. If you ever looked at the end tanks of the stock ICs, you'll have no second thought going with the upgraded ICs. They were so restricted!

Of course, the hp gain is also based on other mods that the OP has.

 

Yeah, the more I think about it intercoolers are probably going to be first on my list of parts to be updated. That and intake pipes once I find a set of those at a reasonable cost. Installing them will of course be "fun". With the intercoolers I at least feel like I can do them myself in my current tiny garage!
