I was thinking of getting Magnusson supercharger for my SS convertible, but the local shop said he recommended a Procharger as there would be heat saturation with any supercharger that sits atop the engine in Nevada or Arizona, and they lose about 50 hp once heated up.

It's currently around 115 degrees here but no idea how that affects what kind of supercharger is best. Does anyone know about this?

The reason I was thinking of a PD was since the convertible is a good 250 lbs heavier that the immediate boost would be an asset.

He's asking $2000 to install and tune.

The ProCharger will heat soak as well. But it also isn't "quite" as bad not being attached. But it is still contained under the hood.

The Magnuson supercharger has a constant supply of cool water running through it, Heat saturation would only be a problem if the water pump quit.

Feel free to call with any questions.

Mine has no problem with heat soak even with back to back runs at the track in 90 plus temps. I ran 10.78@129 when it was 92 degrees and DA was over 3600.

What is DA? I take it 3600 is good?

3600 sucks a lot. Good DA is 0 or negative, that's when the motor can make maximum hp and torque. Track becomes slick and greasy.

DA = Density Altitude

I own both, I have a tvs2300 on my denali pickup and a procharger on my camaro. the maggie is great and keeps the iat cool enough for what i do with the truck, but not sure it'll stay cool in a camaro under constant abuse. my procharger gets warm if i am constantly beating it, but cools rather quickly after i ease up.

Thanks, looks like I can expect between 4200 and 5900, estimating with this (http://airdensityonline.com/track-fo...otor_Speedway/)

I feel if the heat was such an issue then large auto manufactures wouldn't equip vehicles with PD blowers from the factory. Remember the Magnuson is built to OE specs and it's underdriven. I live in Los Angeles and haven't noticed any power drop with this heat wave. Not 120* only around 90* but I'd be more concerned with what type of sunscreen I was going to apply with a Vert in 120* weather

So I called another Las Vegas performance shop and he said that the first shop I called was completely wrong for the same reasons already mentioned above (the liquid cooling, the fact that Chevy uses a PD from the factory anyway). He also said that if anything the ProCharger would be hotter. I won't mention either shop's name until I know what's what but shop #2 seems to have a bit more reputation, especially in the Corvette forums.

IDK about a centri with an air-to-air intercooler being hotter, I think the majority consensus is that air-to-air is way more efficient and your IAT lower with centri - i mean it's one of the known pro's of a centri over a PD.

At least in my limited knowledge of the topic.

Let's not forget early C7 Z06 heat soak issues - just because OEM use them, doesn't mean they aren't hot.

There are many variables that affect which choice to make. My first question is how much power do you really want to make? The second question is where are you going to drive the car, specifically will you ever put the car on a road-racing track? You are really going to have to be driving gonzo on public roads to get these cars really hot. There is just too much airflow through the intercoolers in the grill on the highway for it to really be a problem. As soon as you coast for a little bit everything comes right back into normal ranges.

Honestly I favor the PD blower and as long as you plan to run the stock pulleys it should be fine but if you start to increase the blower speed that southern heat makes a huge difference and they get really hot if they can't get a rest..... like what happens on a road course.

Nothing against drag racing but 11 seconds of wide open throttle isn't much when you get several minutes of rest on the return road, try to run the return road wide open and hit the 1/4 wide open for 30 straight minutes and see what happens to your temps...and 1/4 mile times. That is what happens when you road race.

I do personally like air to water systems. ProCharger now has one as well.
ProChargers systems
HO air-to-air - Standard on the HO system (upgradeable at time of purchase to Stage 2)
Stage 2 air-to-air - Standard on STG2 system (upgradeable to "Race" unit at time of purchase)
Race air to air - Largest available air-to-air unit for maximum cooling of charge temps
Competition Race air to water - For competition use and power levels exceeding 1,000+ hp
