I'm not sure it matters... Just thinking out loud the temp decrease (therefore pressure decrease) is post IC where as in a way the blower only cares what pressure is pre IC at its outlet. Not positive how that effect would transfer to pre IC boost.

Right? Or am I over thinking that? Will the temp decrease make the air flow through the IC faster too because the lower manifold is, in a way, a low pressure zone making boost pre IC lower as well even without the temp decrease?

 

VERY nicely done. Feed the intercooler cooler coolant and more of it. It works! What's the GPM on your coolant pump? I'm running a really oversized h/e along with the standard Maggie h/e. That along with an 11gpm pump.

I see cruising IAT's around 10 degrees over ambient. Mine go up 25 to 30 degrees over ambient at 12psi. Recovery is immediate. Also inject low temp WW fluid. I think it's about a 50/50 mix of water and methanol. Secondary h/e is a full sized radiator with e-fans mounted in the bed. I know, just a little overkill....

 

I believe my pump is rated at 4.8 GPM but it maintains a strong flow rate under pressure also which many do not. At zero pressure its like 10gpm.

 

Yeah, the centrifugal pumps are notorious for that. A little back pressure and they go to ****. I had a couple of Mezierre pumps that were rated high, but were low on performance. Plus, they didn't last any time at all.

 

Mine has the same flow rating as the ZL1 pump.

 

Don't remember the brand of pump I'm using now, but did replace the impeller one time. It looks very similar to the impeller on the water pump used on my Yamaha outboard motor. I guess you'd call it an axial flow pump. Definitely not a centrifugal type pump.

 

Wow! Very extreme and I love it haha

 

here is some good info on pumps Intercooler pump flow test data - Yellow Bullet Forums

I was going to use a bilge pump in the water tank till I read that thread. I never even thought about how restrictive the Maggie intercooler/watermanifold is

 

I still cannot get my IATs down to what I would consider reasonable. I am usually 30-50* above ambient and if I go WOT they quickly increase. I have tried everything except a larger HX or a chiller. I don't really have the room for a larger HX as my Trucool is mounted up front as well, plus my radiator temps get up in the summer with the HX that I have now, but I am tempted by the chiller.

The newer TVS blowers are more efficient, I guess, or have a larger intercooler in the intake than the older MP122?
